Abstract:

Introduction Several US studies have investigated the criminal behaviour among homeless individuals with severe mental illness . But to date , no studies have been carried out in Spain . Method A retrospective observational study was conducted on a sample of 118 patients selected from a psychiatric care program for homeless individuals with severe mental illness . Factors associated with criminal behaviour were analysed by comparing 2 groups , with and without criminal records . Results Of the total sample studied , 24 .6% had a criminal record , and 58 .6% of them had entered prison . Significant differences between groups were found for the variables of gender , pending sentences , duration of homelessness , multiple substance use , disease awareness , and severity of psychotic symptoms . Conclusions In the population of homeless individuals with severe mental illness , regardless of gender , the co - existence of comorbidity with multiple substance use , and a prolonged duration of homelessness , is the most important risk factor for criminal behaviour .
