Forensic psychologists play a vital role in the criminal justice system, especially within diversion programs. These programs aim to redirect offenders from traditional incarceration to alternative treatments or interventions. Forensic psychologists assess, diagnose, and recommend appropriate pathways for offenders, helping to ensure justice and rehabilitation. As the criminal justice system continues to evolve toward more evidence-based and therapeutic approaches, the expertise of forensic psychologists has become increasingly essential in creating effective pathways for individuals whose criminal behavior is linked to mental health conditions, substance abuse, or other underlying issues.
Understanding Diversion Programs in the Criminal Justice System
Diversion programs are initiatives designed to address the underlying issues contributing to criminal behavior. Instead of serving time in prison, offenders may participate in counseling, community service, or educational programs. These programs aim to reduce recidivism and promote positive societal reintegration. Diversion programs are initiatives in which persons with serious mental illness who are involved with the criminal justice system are redirected from traditional criminal justice pathways to the mental health and substance abuse treatment systems.
Diversion programs connect people to support and services that address underlying needs, and are best for people who need access to substance use or mental health treatment. Rather than focusing solely on punishment, these programs recognize that many individuals enter the criminal justice system due to circumstances that can be addressed through appropriate intervention and support.
The Evolution and Growth of Diversion Programs
Diversion emerged in the 1970s amid rising caseloads, with California's 1975 statute pioneering deferred entry of judgment. The 1980s crack epidemic spurred drug courts, starting with Miami's 1989 pilot. The Violent Crime Control Act (1994) funded initial expansion; Second Chance Act (2008) supported reentry variants. The evolution of these programs reflects a growing understanding that incarceration alone does not address the root causes of criminal behavior.
Diversion programs operate at federal, state, and local levels, but they are most prevalent in state systems, where they resolve 18–22 percent of felony arrests nationwide as of 2025. This significant percentage demonstrates the widespread adoption of diversion as a viable alternative to traditional prosecution and incarceration.
Types of Diversion Programs
Diversion programs can be categorized based on when they occur in the criminal justice process. There are two main forms of diversion programs: pre-booking (or prearrest) and postbooking (including mental health courts). Understanding these different types is crucial for forensic psychologists who work within these systems.
Pre-Booking (Pre-Arrest) Diversion
Prebooking programs divert the PMI from being arrested and charged and, thus, from criminal justice involvement entirely. That is, for PMIs involved in prebooking diversion programs, law enforcement has used their discretion to not arrest them. These programs represent the earliest possible intervention point and can prevent individuals from entering the criminal justice system altogether.
After an arrest, someone's fate is largely in the hands of the prosecutor, who has the power to divert them before they are charged with a crime. Pre-charge diversion programs, also referred to as prosecutor-led interventions, allow prosecutors to reduce incarceration by using their discretion to divert people away from the criminal legal system. This prosecutorial discretion is a critical component of effective diversion strategies.
Post-Booking Diversion
Post-booking diversion programs are the more common type of jail diversion program in the United States. After formal charges have been filed, post-booking programs screen individuals to determine the presence of mental or substance use conditions. These programs involve prosecutors, defense lawyers attorneys, courts and mental health providers in a deliberative process aimed at disposing of the case without additional jail time.
If someone has already been charged with a crime, pretrial diversion programs allow people to go through programs, like problem-solving courts, that have completion requirements and sometimes require them to enter a plea. These programs offer structured pathways for individuals to address their underlying issues while their criminal cases are pending.
Mental Health Courts and Specialized Diversion Programs
Mental health courts (MHCs) are postbooking jail diversion programs that aim to divert justice-involved individuals with serious mental illnesses out of the court system and into community-based treatment without jeopardizing public safety. These specialized courts represent a significant innovation in how the justice system addresses the intersection of mental illness and criminal behavior.
Mental health courts are an example of a post-booking jail diversion program. Mental health courts have been effective at diverting persons charged with non-violent crimes away from jail or prison to community mental health services. The success of these courts has led to their proliferation across the United States and other countries.
Beyond mental health courts, other specialized diversion programs have emerged to address specific populations. Military (or Veterans) Diversion Program (Penal Code 1001.80): defendants are often eligible for a treatment and diversion program for the following conditions: PTSD, sexual trauma, traumatic brain injury, substance abuse, or mental health problems. These specialized programs recognize that different populations may have unique needs requiring tailored interventions.
The Critical Role of Forensic Psychologists in Diversion Programs
Forensic psychologists serve as essential bridges between the mental health and criminal justice systems. Their specialized training allows them to understand both the clinical aspects of mental health conditions and the legal requirements of the criminal justice system. This dual expertise makes them uniquely qualified to contribute to diversion programs in multiple capacities.
Comprehensive Assessment and Evaluation
One of the primary functions of forensic psychologists in diversion programs is conducting thorough psychological evaluations. Diversion programs screen justice-involved individuals for the presence of psychiatric disorders, and after negotiations take place with attorneys and treatment providers, these programs link participants with community-based treatment programs in lieu of incarceration. These assessments go far beyond simple diagnostic screening.
Diversion evaluations are a type of forensic mental health assessment (FMHA) conducted to assist the courts in making decisions regarding diversion eligibility. As a result, they should follow the general principles of FMHA and the American Academy of Psychiatry and Law Practice Guideline for Forensic Assessment. This standardization ensures that evaluations meet rigorous professional and legal standards.
Forensic psychologists conduct comprehensive evaluations that examine multiple dimensions of an individual's functioning. These assessments typically include clinical interviews, psychological testing, review of medical and criminal records, collateral interviews with family members or treatment providers, and assessment of the individual's current mental status. The goal is to develop a complete picture of the individual's mental health needs and how these needs relate to their criminal behavior.
Forensic psychologists conduct thorough evaluations that bridge the gap between clinical diagnosis and legal standards. As seasoned professionals with expertise in both legal and psychological arenas, Dr. Anderson and I ensure our evaluations are not only rooted in clinical science but also meet the stringent requirements of the court. This dual focus on clinical accuracy and legal relevance is what distinguishes forensic psychological evaluations from standard clinical assessments.
Establishing the Link Between Mental Illness and Criminal Behavior
A critical aspect of diversion evaluations is establishing whether and how a mental health condition contributed to the alleged criminal behavior. In California, Penal Code § 1001.36 permits diversion if the defendant can demonstrate that their mental illness substantially contributed to the offense. This requirement places significant responsibility on forensic psychologists to carefully analyze the relationship between mental illness and criminal conduct.
The first step is to explore the defendant's mental health history and assess how it relates to the alleged criminal behavior. Our task is to evaluate whether the mental illness contributed to the offense in a way that qualifies for diversion. This analysis requires both clinical expertise and an understanding of legal standards.
For example, a defendant with a history of Schizoaffective Disorder who engaged in criminal behavior during a psychotic episode may be a prime candidate for diversion. However, without a forensic psychologist to connect their psychiatric state to their actions, the court may not recognize this link. This illustrates the crucial role forensic psychologists play in helping courts understand the complex relationship between mental illness and behavior.
Risk Assessment and Public Safety Evaluation
Forensic psychologists play a vital role in assessing the risk of reoffending, which is essential for determining whether an individual is suitable for diversion rather than traditional prosecution. Risk assessment is a sophisticated process that involves evaluating multiple factors that may contribute to future criminal behavior. These assessments help courts make informed decisions about whether diversion is appropriate and what level of supervision and intervention may be necessary.
Forensic psychologists utilize validated risk assessment instruments and structured professional judgment to evaluate an individual's likelihood of reoffending. These tools consider factors such as criminal history, substance abuse patterns, mental health symptoms, social support systems, employment stability, and treatment compliance. The goal is to provide courts with an evidence-based assessment of risk that can inform decision-making about diversion eligibility and program placement.
Risk assessment in the diversion context differs from traditional criminal risk assessment in important ways. Rather than simply predicting the likelihood of future criminal behavior, forensic psychologists must also assess how treatment and support services might mitigate that risk. This requires understanding not only risk factors but also protective factors and the individual's capacity to benefit from intervention.
Public safety is a paramount concern in diversion programs, and forensic psychologists help ensure that diversion does not compromise community safety. Their assessments help identify individuals who can be safely managed in the community with appropriate treatment and supervision, while also identifying those who may require more intensive interventions or for whom diversion may not be appropriate.
Treatment Planning and Recommendations
Beyond assessment, forensic psychologists develop personalized treatment plans tailored to address the specific needs identified in their evaluations. These treatment plans are comprehensive and address multiple domains of functioning, including mental health symptoms, substance abuse issues, social support needs, housing stability, employment or educational goals, and any other factors that may contribute to criminal behavior.
Effective treatment planning requires forensic psychologists to have extensive knowledge of available community resources and treatment modalities. They must be familiar with evidence-based treatments for various mental health conditions, substance abuse treatment programs, supported housing options, vocational rehabilitation services, and other community supports. This knowledge allows them to make realistic and appropriate recommendations that can be implemented within the community.
Treatment plans developed by forensic psychologists typically include specific, measurable goals and objectives. These might include attending individual therapy sessions, participating in group treatment, taking prescribed medications as directed, maintaining sobriety, securing stable housing, obtaining employment or education, and developing healthy coping skills. The specificity of these plans helps ensure accountability and provides clear benchmarks for measuring progress.
Forensic psychologists also consider the individual's readiness for change and motivation for treatment when developing recommendations. They may recommend motivational interviewing or other engagement strategies for individuals who are ambivalent about treatment. Understanding stages of change and how to match interventions to an individual's readiness is crucial for developing effective treatment plans.
Ongoing Monitoring and Progress Reporting
The role of forensic psychologists extends beyond initial assessment and treatment planning. Many forensic psychologists provide ongoing monitoring of participants' progress in diversion programs and submit regular reports to the court or program administrators. This monitoring function is essential for ensuring accountability and identifying any emerging issues that may require intervention.
Progress monitoring typically involves regular contact with the diversion participant, coordination with treatment providers, review of treatment attendance and compliance records, periodic reassessment of mental health symptoms and functioning, and evaluation of progress toward treatment goals. Forensic psychologists synthesize this information into comprehensive reports that inform the court about the participant's engagement and progress.
When participants struggle with compliance or experience setbacks, forensic psychologists can provide valuable input about the reasons for these difficulties and recommend appropriate responses. Rather than simply reporting non-compliance, they can help courts understand whether difficulties stem from worsening mental health symptoms, substance use relapse, environmental stressors, or other factors. This nuanced understanding allows for more therapeutic and effective responses to challenges.
Forensic psychologists also play an important role in determining when participants have successfully completed diversion programs. They assess whether treatment goals have been achieved, symptoms have been adequately addressed, and the individual has developed skills and supports necessary for sustained success. Their recommendations help courts make informed decisions about case disposition and program completion.
Expert Testimony and Court Consultation
Forensic psychologists frequently provide expert testimony in diversion hearings, helping judges, prosecutors, and defense attorneys understand complex mental health issues and their relationship to criminal behavior. Their testimony can be crucial in determining whether an individual is eligible for diversion and what conditions should be imposed.
Expert testimony from forensic psychologists typically addresses several key issues: the nature and severity of the individual's mental health condition, how the mental health condition contributed to the alleged criminal behavior, the individual's amenability to treatment, the risk of reoffending with and without treatment, and recommended treatment interventions and supervision conditions. This testimony must be presented in language that is accessible to legal professionals and lay persons while maintaining scientific accuracy.
Beyond formal testimony, forensic psychologists often serve as consultants to diversion programs, helping to develop program policies and procedures, train staff on mental health issues, evaluate program effectiveness, and troubleshoot challenging cases. This consultative role allows them to contribute to the overall functioning and improvement of diversion programs.
The Prevalence of Mental Illness in the Criminal Justice System
Understanding the scope of mental illness within the criminal justice system helps contextualize the importance of diversion programs and the role of forensic psychologists. An estimated 900,000 persons with serious mental illness are booked into U.S. jails annually. This staggering number highlights the extent to which the criminal justice system has become involved in managing individuals with mental health needs.
Approximately 10% to 15% of jail and prison inmates have a serious mental illness compared with about 3% of the general population. This dramatic overrepresentation of individuals with mental illness in correctional settings reflects systemic issues in how society addresses mental health needs and the criminalization of mental illness.
Moreover, PMIs who are involved in the justice system tend to have repeated, "revolving-door" contact with law enforcement and the courts. This pattern of repeated justice involvement underscores the failure of traditional criminal justice approaches to address the underlying mental health needs that contribute to criminal behavior.
It has been said that U.S. jails and prisons have become de facto mental health institutions. This troubling reality has prompted increased attention to diversion programs as a more appropriate and effective response to individuals whose criminal behavior is linked to mental illness.
Evidence of Effectiveness: Do Diversion Programs Work?
The effectiveness of diversion programs has been the subject of considerable research, and the evidence generally supports their use, particularly for reducing incarceration and improving access to treatment. However, the evidence regarding recidivism reduction is more mixed and depends on various factors including program design, participant characteristics, and the quality of treatment provided.
Impact on Recidivism
They reduce recidivism by 38–50 percent compared to standard prosecution, saving an estimated $4–$12 for every $1 invested through avoided incarceration and court costs. These impressive figures demonstrate the potential of well-designed diversion programs to reduce repeat offending while also generating significant cost savings.
Meta-analyses show drug court graduates recidivate 38–50 percent less than traditional defendants, with mental-health courts reducing rearrests by 45 percent. These meta-analytic findings provide strong evidence for the effectiveness of specialized diversion courts in reducing recidivism among participants who successfully complete the programs.
A 2024 NIJ study found felony rearrest rates dropped from 40 percent to 12 percent in one county and 50 percent to 35 percent in another over two years. These recent findings continue to support the effectiveness of diversion programs in reducing recidivism, though the variation between counties highlights the importance of program quality and implementation.
However, not all research has found consistent evidence of recidivism reduction. The review revealed little evidence of the effectiveness of jail diversion in reducing recidivism among persons with serious mental illness. This finding suggests that while some diversion programs are effective at reducing recidivism, others may not achieve this outcome, highlighting the importance of program design and quality.
Reduction in Incarceration
Even when recidivism reduction is not consistently demonstrated, diversion programs have shown more consistent success in reducing incarceration. However, evidence was found that jail diversion initiatives can reduce the amount of jail time that persons with mental illness serve. This outcome is significant in its own right, as it reduces the harmful effects of incarceration on individuals with mental illness and alleviates jail overcrowding.
Mental health courts in the four studied cities were shown to have statistically significant reductions in participants' rates of arrests and incarceration days at the 18-month follow-up. This finding from a multi-site study provides robust evidence that mental health courts can effectively reduce both arrests and time spent incarcerated.
Such programs reduce arrests, jail days, hospital stays and total criminal justice expenditures. The reduction in jail days and hospital stays represents tangible benefits both for participants and for the systems involved, freeing up resources that can be redirected to more appropriate interventions.
Improved Access to Treatment and Services
Beyond criminal justice outcomes, diversion programs are effective at connecting participants with needed mental health and substance abuse treatment. Typically, diversion programs are premised on the notion that PMIs who access and engage in community treatment will be less likely to have police contact and less likely to be charged with crimes, thereby reducing the repeated cycling. This connection to treatment is a primary mechanism through which diversion programs are expected to achieve their goals.
Preliminary research on the effectiveness of the programs is equivocal but promising, in that diversion can improve the lives of PMIs involved in the criminal justice system. Even when specific criminal justice outcomes are not consistently achieved, the improvement in participants' lives through access to treatment and services represents an important benefit of diversion programs.
Cost-Effectiveness
Cost savings reach $4–$12 per $1 invested, primarily through avoided incarceration. This impressive return on investment makes diversion programs attractive from a fiscal perspective, in addition to their humanitarian benefits. The cost savings come from multiple sources including reduced jail and prison costs, reduced court processing costs, reduced emergency room visits, and improved employment and productivity among participants.
Beyond the benefits to individuals with mental health conditions, diversion programs also benefit the criminal justice system, allowing it to focus on more serious offenders. Such programs are cost-effective; they save courts time, keep dockets from becoming too large, and reduce prison overcrowding. These systemic benefits extend beyond direct cost savings to improved functioning of the criminal justice system as a whole.
Challenges and Limitations of Diversion Programs
While diversion programs offer significant promise, they also face important challenges and limitations that must be acknowledged and addressed. Understanding these challenges is essential for forensic psychologists working within these systems and for policymakers seeking to improve diversion programs.
Access and Equity Issues
However, access remains uneven, with barriers for rural residents and those with prior records. Geographic disparities in access to diversion programs mean that individuals in rural areas may not have the same opportunities for diversion as those in urban areas with more developed programs and resources.
Critics note racial disparities in referrals (Black defendants 20 percent less likely to be offered entry) and "net-widening," where minor offenders face more scrutiny than standard prosecution. These racial disparities raise serious concerns about equity and fairness in how diversion programs are implemented. Forensic psychologists and other professionals involved in diversion must be aware of these disparities and work to ensure that their assessments and recommendations do not perpetuate bias.
The availability of diversion programs depends on the jurisdiction, the nature of the crime (usually non-violent offenses), and, in many cases, the exercise of prosecutorial discretion. This variability means that similarly situated individuals may have very different opportunities for diversion depending on where they are prosecuted, raising questions about fairness and consistency.
Program Completion and Dropout Rates
High dropout rates (40–50 percent) stem from treatment barriers, and funding shortages limit rural access to programs. These high dropout rates represent a significant challenge for diversion programs, as participants who fail to complete programs may face more severe consequences than they would have faced without entering diversion.
People who have substance use disorders or other mental disorders and who are very poor often struggle to meet requirements and are much less likely to complete programs successfully. When they are sent back to court, they often face penalties that are more severe than those they would have received if they had not entered diversion in the first place. This reality highlights the importance of ensuring that diversion programs are designed with realistic requirements and adequate support for participants facing multiple challenges.
Forensic psychologists can play an important role in addressing completion challenges by conducting thorough assessments of participants' capacity to meet program requirements, recommending appropriate accommodations or modifications for individuals with significant barriers, identifying and addressing obstacles to compliance early in the process, and helping programs develop more flexible and individualized approaches to supervision and support.
Program Quality and Fidelity
Some programs lack fidelity to evidence-based models, reducing effectiveness. Not all diversion programs are created equal, and programs that do not adhere to evidence-based principles may not achieve the intended outcomes. This variability in program quality underscores the importance of ongoing evaluation and quality improvement efforts.
Forensic psychologists can contribute to improving program quality by staying current with research on effective diversion practices, advocating for evidence-based approaches in program design and implementation, participating in program evaluation efforts, and providing training and consultation to enhance program staff's understanding of mental health issues and effective interventions.
Balancing Treatment and Accountability
Diversion programs must balance therapeutic goals with accountability and public safety concerns. This balance can be challenging, particularly when participants struggle with compliance or experience relapses. Forensic psychologists help navigate this balance by providing informed perspectives on when therapeutic responses are appropriate versus when more structured accountability measures may be necessary.
These features include sharing a common goal of reducing recidivism rates of PMIs, relying on a therapeutic jurisprudence model, having predefined target populations, using a carrot-and-stick approach to achieve compliance, maintaining collaborations across multiple systems of care, and sometimes mandating treatment. The "carrot-and-stick" approach reflects this balance between support and accountability, though the optimal balance may vary depending on individual circumstances.
The Broader Impact of Forensic Psychologists on the Justice System
The involvement of forensic psychologists in diversion programs has several positive impacts that extend beyond individual cases to influence the broader criminal justice system and society.
Reducing Prison Overcrowding
By identifying appropriate candidates for diversion and supporting their successful completion of programs, forensic psychologists contribute to reducing the number of individuals incarcerated in jails and prisons. This reduction in incarceration helps address the serious problem of prison overcrowding that affects many jurisdictions. Overcrowded facilities are associated with increased violence, reduced access to programs and services, and poorer outcomes for incarcerated individuals.
The work of forensic psychologists in diversion programs helps ensure that jail and prison beds are reserved for individuals who truly require incarceration for public safety reasons, rather than being occupied by individuals whose primary need is mental health or substance abuse treatment. This more appropriate use of correctional resources benefits both the individuals diverted and the overall functioning of the correctional system.
Addressing Mental Health Needs
Forensic psychologists play a crucial role in ensuring that individuals with mental health needs receive appropriate treatment rather than being warehoused in correctional facilities ill-equipped to address those needs. Additional costs are saved when those with mental illnesses are removed from prisons and provided with appropriate treatment instead. Beyond cost savings, this shift represents a more humane and effective approach to addressing mental illness.
By connecting justice-involved individuals with community-based mental health services, forensic psychologists help address gaps in the mental health system and ensure that individuals who might otherwise fall through the cracks receive needed care. This connection to treatment can have lasting benefits for individuals' mental health, functioning, and quality of life.
Promoting Rehabilitation and Reducing Recidivism
The treatment-oriented approach supported by forensic psychologists' work in diversion programs promotes rehabilitation rather than mere punishment. Studies show that diversion of persons with mental and substance use conditions accused of misdemeanor crimes into appropriate, community-based mental health treatment programs allows for better long-term results for offenders. This focus on rehabilitation aligns with evidence showing that treatment and support are more effective than punishment alone in reducing recidivism.
Forensic psychologists' expertise in developing individualized treatment plans and matching individuals with appropriate interventions is essential for achieving rehabilitative goals. Their understanding of what works in reducing criminal behavior allows them to recommend interventions most likely to promote lasting change.
Supporting Fairer and More Individualized Justice
The detailed assessments and individualized recommendations provided by forensic psychologists support more nuanced and individualized justice decisions. Rather than applying one-size-fits-all approaches, courts can make decisions informed by a thorough understanding of each individual's circumstances, needs, and potential for rehabilitation.
Participants find diversion fairer than the traditional court system. In a 2018 study in Harris County, Texas, researchers found positive outcomes for diversion programs in criminal courts. This perception of fairness is important not only for participants' engagement with the process but also for the legitimacy of the justice system more broadly.
Forensic psychologists help ensure that justice decisions account for the role of mental illness, trauma, cognitive impairments, and other factors that may have contributed to criminal behavior. This more comprehensive understanding supports justice that is both fair and effective in addressing the root causes of criminal behavior.
Advancing Therapeutic Jurisprudence
The work of forensic psychologists in diversion programs advances the principles of therapeutic jurisprudence, which seeks to use the law and legal processes to promote the psychological and emotional well-being of individuals involved in the legal system. Therapeutic jurisprudence recognizes that legal processes can have therapeutic or anti-therapeutic consequences and seeks to maximize therapeutic outcomes while maintaining justice.
Forensic psychologists embody therapeutic jurisprudence principles by focusing on treatment and rehabilitation rather than punishment alone, considering the psychological impact of legal processes and decisions, promoting participant engagement and empowerment in treatment planning, and advocating for approaches that support long-term well-being and successful community reintegration.
Training and Qualifications of Forensic Psychologists
The complex and specialized work that forensic psychologists perform in diversion programs requires extensive training and expertise. Understanding the qualifications of forensic psychologists helps contextualize the value they bring to these programs.
Educational Requirements
Forensic psychologists typically hold doctoral degrees (PhD or PsyD) in psychology with specialized training in forensic psychology. This training includes coursework in psychological assessment, psychopathology, research methods, ethics, and specialized forensic topics such as criminal behavior, risk assessment, competency evaluation, and the intersection of psychology and law.
Many forensic psychologists complete specialized internships and postdoctoral fellowships in forensic settings, gaining supervised experience conducting forensic evaluations, providing expert testimony, and working within criminal justice and legal systems. This intensive training ensures that forensic psychologists have both the clinical skills and the legal knowledge necessary to function effectively in forensic contexts.
Licensure and Certification
Forensic psychologists must be licensed to practice psychology in their jurisdiction, which requires completing doctoral education, supervised clinical experience, and passing a comprehensive examination. Beyond basic licensure, many forensic psychologists pursue board certification in forensic psychology through the American Board of Professional Psychology (ABPP), which requires demonstrating advanced competence in forensic practice through examination and peer review of work samples.
Continuing education is essential for forensic psychologists to stay current with evolving research, legal standards, and best practices. Professional organizations such as the American Psychology-Law Society provide resources, training opportunities, and practice guidelines to support ongoing professional development in forensic psychology.
Specialized Knowledge and Skills
Effective work in diversion programs requires forensic psychologists to possess specialized knowledge in several areas including mental health disorders and their treatment, substance abuse and addiction, risk assessment methodologies and instruments, criminal justice system processes and procedures, legal standards for diversion eligibility, community resources and treatment options, cultural competence and awareness of diversity issues, and trauma-informed approaches to assessment and intervention.
Beyond knowledge, forensic psychologists must develop skills in communicating complex psychological concepts to legal professionals and lay persons, maintaining objectivity and avoiding bias in evaluations, managing ethical dilemmas that arise at the intersection of clinical and legal roles, collaborating effectively with multidisciplinary teams, and providing testimony that is both scientifically sound and legally relevant.
Ethical Considerations in Forensic Psychology and Diversion Work
Forensic psychologists working in diversion programs navigate complex ethical terrain that requires careful attention to professional standards and values. The dual role of serving both clinical and legal functions creates unique ethical challenges that must be thoughtfully managed.
Maintaining Objectivity and Avoiding Bias
Forensic psychologists must maintain objectivity in their evaluations and recommendations, even when they may personally believe that diversion is in an individual's best interest. This requires basing opinions on thorough assessment and evidence rather than advocacy for a particular outcome. Forensic psychologists must be willing to provide opinions that may not favor the party who retained them and to acknowledge limitations in their data or conclusions.
Awareness of potential sources of bias is essential, including confirmation bias, cultural bias, and bias related to the evaluator's own experiences or values. Forensic psychologists must actively work to identify and mitigate these biases through use of structured assessment methods, consultation with colleagues, and ongoing self-reflection about their own assumptions and perspectives.
Informed Consent and Role Clarification
Forensic evaluations differ from traditional clinical relationships in important ways, and forensic psychologists must clearly explain these differences to individuals being evaluated. This includes clarifying that the evaluation is being conducted for legal purposes rather than treatment, explaining the limits of confidentiality and how information will be used, informing individuals that the psychologist's primary obligation is to provide objective information to the court rather than to advocate for the individual, and ensuring that participation is truly voluntary or, if court-ordered, that individuals understand the consequences of non-participation.
Confidentiality and Privacy
Confidentiality in forensic evaluations is limited in ways that differ from traditional clinical practice. Information obtained during forensic evaluations is typically shared with the court, attorneys, and other parties involved in the legal proceedings. Forensic psychologists must clearly explain these limitations and ensure that individuals understand how their information will be used and disclosed.
At the same time, forensic psychologists must protect privacy to the extent possible by limiting disclosures to information relevant to the legal questions at hand, storing records securely and in compliance with applicable laws and regulations, and being mindful of the potential impact of disclosures on individuals' dignity and reputation.
Competence and Scope of Practice
Forensic psychologists must practice within the boundaries of their competence, which requires ongoing education and training in relevant areas. They should decline cases that fall outside their areas of expertise and seek consultation when facing unfamiliar issues or populations. This commitment to competence protects both the individuals being evaluated and the integrity of the legal process.
Future Directions and Innovations in Diversion Programs
The field of diversion programs continues to evolve, with ongoing innovations and reforms aimed at improving effectiveness and expanding access. Forensic psychologists will play important roles in these developments.
Expansion and Standardization
The expansion of diversion reflects a shift toward evidence-based reforms, with federal programs growing rapidly since 2022 and state initiatives incorporating specialized courts for veterans, youth, and trafficking survivors. This expansion represents growing recognition of the value of diversion approaches and the need to address the diverse needs of different populations involved in the justice system.
Reforms include 2025 DOJ equity grants and telehealth integration. These recent reforms address some of the challenges facing diversion programs, including equity concerns and access barriers. Telehealth integration, in particular, has potential to expand access to services for individuals in rural areas or those facing transportation or other barriers to in-person services.
Addressing Equity and Access
Ongoing efforts to address racial and socioeconomic disparities in access to diversion programs will be crucial for ensuring that these programs fulfill their promise of providing fairer and more effective justice. This includes examining and addressing bias in referral processes, expanding programs to underserved geographic areas, reducing financial barriers to participation, and ensuring that program requirements are realistic and achievable for individuals facing multiple challenges.
Forensic psychologists can contribute to equity efforts by being aware of and addressing potential bias in their own assessments and recommendations, advocating for program policies that promote equitable access, conducting research on disparities and effective strategies for addressing them, and providing training to other professionals on cultural competence and bias reduction.
Integration of Technology
Technology offers opportunities to enhance diversion programs through telehealth services that expand access to treatment, electronic monitoring and communication tools that support supervision and engagement, data systems that facilitate coordination among providers and tracking of outcomes, and risk assessment tools that incorporate machine learning and artificial intelligence.
However, technology integration also raises important considerations about privacy, equity of access to technology, and the appropriate role of algorithmic decision-making in justice contexts. Forensic psychologists will need to engage with these issues as technology becomes increasingly integrated into diversion programs.
Enhanced Focus on Trauma-Informed Approaches
Growing recognition of the role of trauma in criminal behavior has led to increased emphasis on trauma-informed approaches in diversion programs. These approaches recognize the prevalence of trauma among justice-involved individuals, understand the impact of trauma on behavior and functioning, avoid re-traumatization through program policies and practices, and incorporate trauma-specific interventions when appropriate.
Forensic psychologists are well-positioned to advance trauma-informed practices in diversion programs through their expertise in trauma assessment and treatment, their understanding of how trauma affects behavior and decision-making, and their ability to train other professionals in trauma-informed approaches.
Improved Outcome Measurement and Program Evaluation
As diversion programs continue to expand, there is increasing emphasis on rigorous evaluation to determine what works, for whom, and under what conditions. This includes developing standardized outcome measures, conducting randomized controlled trials and other rigorous evaluation designs, examining cost-effectiveness and return on investment, and identifying program components and practices associated with better outcomes.
Forensic psychologists contribute to evaluation efforts through their research expertise, their understanding of appropriate outcome measures for justice-involved populations, and their ability to interpret findings and translate them into practice recommendations.
Collaboration and Multidisciplinary Teamwork
Effective diversion programs require collaboration among multiple stakeholders and disciplines. Mental Health America recognizes that the development of diversion programs involves negotiation between the mental health system, law enforcement officers, public defenders, prosecutors, court personnel and others in the criminal justice system. Forensic psychologists function as key members of these multidisciplinary teams.
Successful collaboration requires forensic psychologists to communicate effectively with professionals from different disciplines and backgrounds, understand the perspectives and constraints of different system partners, build relationships based on mutual respect and shared goals, and navigate disagreements or conflicts constructively.
The multidisciplinary nature of diversion work enriches the process by bringing diverse perspectives and expertise to bear on complex cases. Judges bring legal expertise and authority, prosecutors and defense attorneys represent different interests and perspectives on appropriate case resolution, treatment providers offer clinical expertise and knowledge of available resources, probation officers provide supervision and monitoring, and peer support specialists offer lived experience and unique insights into recovery and reintegration.
Forensic psychologists serve as bridges between the clinical and legal worlds, translating psychological concepts for legal professionals and helping clinicians understand legal requirements and constraints. This bridging function is essential for effective collaboration and program functioning.
Case Examples: Forensic Psychology in Action
To illustrate the practical application of forensic psychology in diversion programs, consider several hypothetical case examples that demonstrate the range of situations forensic psychologists encounter and the contributions they make.
Case Example 1: Mental Health Diversion for Psychotic Disorder
A 28-year-old individual with a history of schizophrenia is arrested for trespassing and disturbing the peace after entering a business and making threatening statements. The defense attorney requests a forensic evaluation to determine eligibility for mental health diversion. The forensic psychologist conducts a comprehensive evaluation including clinical interview, review of psychiatric records, psychological testing, and collateral interviews with family members and the individual's psychiatrist.
The evaluation reveals that the individual had stopped taking antipsychotic medication several months prior to the incident due to unpleasant side effects and lack of insight into the need for treatment. At the time of the offense, the individual was experiencing active psychotic symptoms including paranoid delusions that led to the threatening behavior. The forensic psychologist's report establishes the link between untreated mental illness and the criminal behavior, assesses the individual as appropriate for diversion based on low risk when stabilized on medication, and recommends a treatment plan including psychiatric medication management, case management services, and supported housing.
Based on this evaluation, the court grants diversion. The forensic psychologist provides ongoing monitoring, submitting quarterly reports on the individual's progress. When the individual struggles with medication compliance, the psychologist recommends switching to a long-acting injectable medication and increasing the frequency of case management contacts. These interventions help the individual successfully complete the diversion program, resulting in dismissal of charges and improved mental health stability.
Case Example 2: Substance Abuse Diversion
A 35-year-old individual with opioid use disorder is arrested for theft after shoplifting to support their addiction. The prosecutor's office screens the case for drug court eligibility and requests a forensic evaluation. The forensic psychologist assesses the individual's substance use history, mental health status, motivation for treatment, and risk factors.
The evaluation reveals a long history of opioid use beginning with prescription pain medication following an injury, progression to heroin use, multiple previous treatment attempts with limited success, co-occurring depression and anxiety, and strong family support. The forensic psychologist determines that the individual is appropriate for drug court and recommends a comprehensive treatment plan including medication-assisted treatment with buprenorphine, intensive outpatient treatment, individual therapy for co-occurring mental health issues, and family therapy to strengthen support systems.
During participation in drug court, the individual experiences a relapse after several months of sobriety. Rather than recommending termination from the program, the forensic psychologist helps the court understand the relapse as part of the recovery process and recommends increased treatment intensity and additional supports. This therapeutic response allows the individual to re-engage with treatment and ultimately achieve sustained recovery and successful program completion.
Case Example 3: Veterans Diversion
A 42-year-old military veteran is arrested for assault following an altercation at a bar. The veteran's attorney requests evaluation for veterans court. The forensic psychologist conducts an evaluation that includes assessment of military service history, trauma exposure, current mental health symptoms, and the relationship between service-related issues and the alleged offense.
The evaluation reveals that the veteran served multiple combat deployments, experienced significant trauma including witnessing the death of fellow service members, has been diagnosed with PTSD and traumatic brain injury, has struggled with anger management and alcohol use since returning from service, and the assault occurred during a PTSD-triggered flashback while intoxicated.
The forensic psychologist's report establishes eligibility for veterans court and recommends a treatment plan specifically tailored to the veteran's needs including trauma-focused therapy such as Cognitive Processing Therapy or Prolonged Exposure, substance abuse treatment with focus on the relationship between PTSD and drinking, anger management and skills training, and connection with VA services and veteran peer support. The veteran successfully completes the program, achieving significant reduction in PTSD symptoms, sustained sobriety, and improved functioning.
Resources and Support for Diversion Programs
Numerous resources are available to support the development and implementation of effective diversion programs. Professional organizations such as the American Psychology-Law Society, the American Academy of Psychiatry and the Law, and the National Association of Forensic Counselors provide training, practice guidelines, and networking opportunities for professionals working in forensic settings.

Conclusion
Forensic psychologists are essential to the success of diversion programs in the criminal justice system. Their expertise ensures that offenders receive appropriate treatment, reducing the likelihood of reoffending and fostering a more effective and humane approach to justice. Through comprehensive assessment and evaluation, risk assessment, individualized treatment planning, ongoing monitoring and support, expert testimony and consultation, and collaboration with multidisciplinary teams, forensic psychologists make invaluable contributions to diversion programs.
The evidence supporting diversion programs continues to grow, demonstrating their effectiveness in reducing incarceration, connecting individuals with needed treatment, and in many cases reducing recidivism. They reduce recidivism by 38–50 percent compared to standard prosecution, saving an estimated $4–$12 for every $1 invested through avoided incarceration and court costs. For defendants, participation offers a pathway to rehabilitation and reintegration, while for the justice system, it alleviates overcrowding and promotes efficient resource allocation.
As diversion programs continue to expand and evolve, forensic psychologists will play increasingly important roles in ensuring that these programs are evidence-based, equitable, and effective. Their work at the intersection of psychology and law helps create a criminal justice system that is more therapeutic, more individualized, and more focused on addressing the root causes of criminal behavior rather than simply punishing it.
These programs recognize that incarceration will not solve homelessness, job and food insecurity, substance use disorders, or other factors that contribute to harm. Working to remedy these problems improves community safety and the health of the community in the long-term. This recognition reflects a fundamental shift in how society approaches criminal justice, moving from a purely punitive model to one that recognizes the complex factors contributing to criminal behavior and seeks to address them through treatment and support.
The future of diversion programs is promising, with ongoing innovations in program design, expanded access through technology and policy reforms, increased focus on equity and addressing disparities, and growing evidence base supporting their effectiveness. Forensic psychologists will continue to be at the forefront of these developments, contributing their expertise to create more effective, humane, and just responses to individuals whose criminal behavior is linked to mental health, substance abuse, or other treatable conditions.
For individuals facing criminal charges who may be eligible for diversion, the involvement of a qualified forensic psychologist can make a critical difference in accessing these programs and achieving successful outcomes. Mental health diversion offers an invaluable opportunity for individuals whose mental illness has played a significant role in their criminal behavior to receive treatment and rehabilitation rather than face the full weight of the criminal justice system. However, successfully navigating the diversion process requires more than a diagnosis—it requires a nuanced understanding of both mental health and the law. That's why hiring a competent forensic psychologist is essential.
Ultimately, the role of forensic psychologists in diversion programs exemplifies the potential for psychology to contribute to social justice and positive social change. By helping to redirect individuals from incarceration to treatment, by promoting rehabilitation over punishment, and by supporting more individualized and therapeutic approaches to justice, forensic psychologists are helping to create a criminal justice system that better serves both individuals and communities. Their work represents a crucial investment in human potential and a recognition that even those who have committed crimes deserve opportunities for healing, growth, and redemption.
