This qualitative focus group study was conducted to evaluate the effectiveness of Crisis Intervention Team (CIT) training for police officers. Thematic analysis of transcripts of focus group discussions revealed that officers report increased knowledge of mental illnesses (which manifests as an improved ability to recognize and respond, reduced stereotyping/stigmatization, greater empathy toward consumers and their caregivers, more patience when dealing with consumers, and fewer arrests/more redirection toward treatment), as well as practical application of learned skills (evidenced by an ability to put individuals with mental illnesses at ease, reduced unpredictability of the crisis situation, and reduced risk of injury). Results highlight the potential for collaboration between law enforcement (and other public safety/criminal justice professions) and the mental health professions in the expanding CIT collaborative model.
