Prevalence of technical delusions in a homeless population sample 

 547 adults with mental illness were homeless at baseline. In the year prior to randomization, 55.8% of participants interacted with police, while 51.7% and 43.0% interacted with police in Study Years 1 and 2, respectively. Of 2,228 charges against participants, 12.6% were due to acts of living and 21.2% were for administration of justice. Of 518 occurrences, 41.1% were for victimization, 45.6% were for mental health assessment, and 22.2% were for suicidal behavior. The odds of any police interaction during the past 90 days was 47% higher for those who were homeless compared to those who were stably housed (95% CI 1.26 to 1.73).
