Continuing Education Activity

The intersection of psychiatric illness and criminal behavior is a complex and often misunderstood area within mental health and legal systems. This educational activity delves into the relationship between mental health disorders and criminal activities, challenging prevalent misconceptions and exploring evidence-based realities. This activity addresses the impact of societal perceptions and media portrayals on the stigma surrounding psychiatric patients. It critically examines the overrepresentation of mental illness in criminal populations, often exacerbated by factors like substance use disorders, homelessness, and inadequate access to mental health care. Through a comprehensive review of psychiatric conditions that may increase the risk of criminal behavior, such as Antisocial Personality Disorder, and the role of substance abuse, participants will gain insight into the nuanced ways in which mental health and criminality intersect. This activity underscores the importance of an interprofessional approach, involving psychiatrists, social workers, legal professionals, and patient advocates, in identifying and mitigating risk factors, providing appropriate care, and navigating the legal implications. The article aims to equip healthcare professionals with a deeper understanding and more effective strategies to support patients at the intersection of psychiatric illness and criminality, ultimately contributing to more informed clinical and legal practices.

Objectives:

  • Identify misconceptions regarding mental illness and criminality.

  • Interpret the evidence that describes the frequency of untoward criminal events in psychiatric patients.

  • Determine the negative consequence of misconceptions regarding persons with mental illness and criminal violence.

  • Understand the role of the interprofessional team in evaluating patients with mental illness in the criminal justice system.

Introduction

The relationship between psychiatric illness and criminality has garnered public interest, particularly following numerous mass shootings in the United States. These events have driven a renewed emphasis on the importance of mental health. However, they have also inadvertently led to a misconception that often conflates mental illness with a predisposition to violence. This misunderstanding is further exacerbated by media portrayals, which frequently depict individuals with psychiatric illnesses as inherently dangerous. Such depictions not only stigmatize those with mental conditions but also deviate from reality: a significant body of research indicates that individuals with mental illnesses are more likely to be victims, rather than perpetrators, of violent crimes.[1] This misconception extends even to the criminal justice system, wherein individuals with mental health conditions often face disproportionate penalties and extended incarcerations compared to their counterparts in the general population. This article delves deep into the multifaceted relationship between psychiatric illness and criminality, challenging preconceived notions and advocating for a more nuanced understanding.[2]

Function

The public's tendency to equate psychiatric illness with criminality often stems from misunderstandings and societal norms. One significant factor contributing to this misconception is the mislabeling of criminals as persons with a mental illness. Such labeling is not always rooted in comprehensive medical or psychiatric evaluations but is influenced heavily by societal perceptions and stereotypes. This perspective is further reinforced when media and popular culture depict criminals as "crazy" or mentally unstable, thereby oversimplifying and misunderstanding the complexities of criminal behavior and mental health.[3]

Within correctional facilities, diagnoses such as Antisocial Personality Disorder (ASPD) are frequently and arbitrarily applied. This practice has sparked debates among professionals about whether ASPD should be regarded as a genuine psychiatric illness or merely a reflection of societal moral judgments. The danger lies in the overuse of such labels, which might be employed as a means for criminals to evade responsibility for their actions by claiming mental illness as a cover. This underscores clinicians' crucial responsibility to ensure that psychiatric diagnoses are based only on evidence-based criteria and rigorous assessments.[4] 

Furthermore, while a significant number of inmates might exhibit symptoms associated with mental disorders, it is essential to differentiate between behaviors resulting from genuine psychiatric conditions and those arising from other factors, such as environmental stresses or learned behaviors. To address these challenges and prevent further misconceptions, it is imperative that mental health professionals, legal authorities, and the media work collaboratively. Educating the public and re-evaluating and refining the diagnostic processes within correctional facilities can serve as initial steps toward resolving these misperceptions.

Issues of Concern

Historically, the interaction between psychiatric illness and criminality traces back to significant shifts in mental health care systems. For instance, the deinstitutionalization movement that began in the 1960s led to the closure of numerous state psychiatric hospitals. Consequently, many psychiatric patients found themselves on the streets, unshielded and unsupported, which naturally led to increased interactions with law enforcement. One glaring manifestation of this interplay is the disproportionate arrest and incarceration of individuals with mental illnesses. These arrests often arise from minor infractions such as jaywalking or displays of wandering behavior, which are misconstrued as threats to public order. A striking study noted that 12 percent of adult psychiatric patients receiving treatment in the San Diego County health system had histories of incarceration. Even more alarming, 28 percent of Connecticut residents treated for schizophrenia and bipolar disorder had experienced arrest or detention at some point.[5]

For many individuals with psychiatric illnesses, encounters with the police lead to entanglements with the courts and subsequent incarcerations. This is exacerbated by a widespread lack of training in the justice system to accurately recognize and respond to mental illness, leading to mischaracterizations and misguided judgments.[6] Furthermore, behaviors that are symptomatic of certain psychiatric illnesses, such as wandering or vocal outbursts, are sometimes wrongfully interpreted as criminal or antisocial. This misperception has fueled an unjustified and inaccurate belief in the causative relationship between psychiatric illness and criminality. This narrative, coupled with a lack of adequate mental health resources, has positioned persons with mental illness in a precarious situation, often at the intersection of health and justice, with the scales tilted unjustly against them.[7]

Clinical Significance

Research suggests that untreated mental illness, especially when combined with active symptoms such as delusions or long-standing paranoia, may increase the potential for violent behavior. Cases in point include individuals experiencing command hallucinations, which may drive them to act in ways they would typically not. However, it's vital to differentiate between actions driven by psychiatric distress and those stemming from criminal intent.[8]

Another notable concern is the presence of comorbidities. Substance use disorder, for instance, stands out as a prominent risk factor. A comorbid substance use disorder can amplify the risk of engaging in violent or criminal behavior among individuals with major psychiatric conditions. Some studies even posit that the rise in violent crimes associated with mental illness might be predominantly attributed to a history of alcohol or drug use.[9]  In patients with a major psychiatric illness with comorbid substance use disorder, there is a four-fold increase in the risk of committing a crime or violence.[10]

Beyond the direct influence of psychiatric symptoms and substance use, other external factors also play a role. Socioeconomic factors such as unemployment and homelessness, combined with secondary effects of mental illness like cognitive impairments, can further compound the risk. For instance, individuals with untreated severe mental illness might find themselves in dire situations, leading them to commit crimes out of desperation or as a response to their environment.

It is also paramount to address the systemic challenges surrounding mental health care. Many individuals with mental illnesses grapple with accessing timely and appropriate treatment. Funding cuts and budgetary constraints in public health sectors have further strained the already limited resources, leading to an unfortunate scenario where individuals might be more likely to engage in criminal activity due to lack of adequate support. In fact, current mental health facility capacities in the U.S. are reminiscent of the severely lacking infrastructure from the 1850s. To address these concerns, we must understand the intricate balance between mental health and potential criminal behavior, ensuring that individuals receive the care they need while dispelling unfounded fears and misconceptions.

Other Issues

A far-sighted national mental health policy with expanded availability and access to treatment, while costly in the short run, could be a cost-effective and sensible approach. By some estimates, a ninety-day treatment in a mental hospital might prevent the 10-year imprisonment of an individual with mental illness. Expanded availability and access to mental health treatment would provide significant savings to society and crime victims. More importantly, it would improve a person with mental illness' quality of life and transform these individuals into productive members of society.

The link between psychiatric illness and criminality is complex and has profound societal implications. There is a great need for in-depth research and imaginative solutions for access and availability to mental health treatment. Currently, there is scant evidence to suggest that mental illness can independently predict criminal behavior. On the contrary, there is ample evidence that shows that persons with mental illness are far more likely to be the victim of violent crime rather than the perpetrator.

Enhancing Healthcare Team Outcomes

To break the links between mental illness and criminality requires an inter-professional team of psychiatrists, social workers, and patient advocates to detect and reduce or eliminate risk factors that lead persons with mental illness to commit a crime. This team approach includes a multi-tiered system that would identify at-risk patients early on and provide resources to prevent situations that bring the persons with mental illness in contact with the criminal justice system such as medical non-compliance and lack of food and shelter. For those individuals already inside the criminal justice system, there needs to be a targeted approach that includes rehabilitation, education, and empowerment. Finally, a concerted effort is required to educate the public at large and those in the criminal justice system, in particular, to dispel misperceptions and prevent mischaracterization, mislabeling of criminals as persons with mental illness and vice versa.
