Table 2. Twelve month prevalence rates of victimisation of patients with depression, substance use disorder and severe mental illness, psychiatric patients overall and the general population.

Criminal victimisation prevalence was measured in 300 outpatients living in Amsterdam, The Netherlands. Face-to-face interviews were conducted with outpatients with depressive disorder (n=102), substance use disorder (SUD, n=106) and severe mental illness (SMI, n=92) using a National Crime Victimisation Survey, and compared with a matched general population sample (n=10865).

Statistical analyses were conducted using SPSS Statistics for Microsoft Windows, a computer software package for statistical analysis. Between group analyses were conducted using the Pearson Chi-square test for dichotomous variables, and ANOVA for continuous variables, Effect sizes for dichotomous variables were obtained with Cramer’s V test. The Bonferroni Test was used as a post hoc test for continuous variables. For comparison of the patient group with the general population we also used a Pearson Chi-square test. To correct for differences between the two samples, IVM data of the general population was weighed for age, gender, ethnicity, level of education and living area.
