INTRODUCTION The Lack of a Link between Behavioral Health Disorders and Violence or Other Crimes Although this paper highlights the association between behavioral health disorders and criminal justice system involvement, readers should be mindful that the majority of people with mental illnesses are not violent and do not commit crimes.12 Such misconceptions have led to stigmatization and barriers to supports and services.* These myths must be countered with available research that does not find such a link between mental illness and violence.13 Research does suggest that some people under the influence of drugs and other substances are more likely to be violent—whether or not they have a mental illness.14 Moreover, the nation’s prisons and jails do hold large numbers of individuals convicted for nonviolent crimes of possession and distribution and for property crimes committed to support their addictions. It is also important to remember that some individuals who are arrested and incarcerated—including those with no mental illnesses—are all more likely to be violent than the general population.15 Traditionally, both criminal justice and behavioral health practitioners believed that mental illnesses are the direct cause of criminal justice involvement (e.g., the voices an individual hears tells him or her to commit a crime), and many local programs targeting people with behavioral disorders who have had encounters with police and other criminal justice officials were designed with this in mind.16 There is also the belief that many individuals are involved in the criminal justice system because their behaviors associated with a mental health disorder bring them into contact with law enforcement for such low-level crimes as trespassing and disturbing the peace. Recent studies, however, have demonstrated that the relationship of mental illness to criminal activity is more nuanced and complex. Researchers looking at the relationship of mental illness and recidivism have found that changes in an individual’s psychiatric symptoms do not necessarily relate to whether or not he or she is rearrested or revoked from community supervision.17 This suggests that interventions to reduce recidivism among people with mental illnesses in the criminal justice system need to not only include traditional mental health treatment, but also incorporate new multifaceted strategies. *The authors, however, in no way suggest that simply having a mental illness diminishes accountability for individuals’ criminal acts. 5
