Violence in women with psychosis in the community: prospective study

摘要

Background Little is known about the determinants of violence in women with psychosis. Aims To identify predictors of violence in a community sample of women with chronic psychosis. Method The 2-year prevalence of physical assault was estimated for a sample of 304 women with psychosis. Baseline socio-demographic and clinical factors were used to identify predictors of assault. Results The 2-year prevalence of assault in the sample was 17%. Assaultive behaviour was associated with previous violence (OR=5.87,95% CI 2.42a€“14.25), non-violentconvictions (OR=2.63,95% CI 1.17a€“5.93), victimisation (OR=2.46, 95% CI1.02a€“5.93), Africana€“Caribbean ethnicity (OR=2.24,95% CI1.02a€“4.77), cluster B personality disorder (OR=2.66, 95% CI1.11a€“6.38) and high levels of unmet need (OR=1.17,95% CI1.01a€“1.35). An interaction between Africana€“Caribbean ethnicity and cluster B personality disorder was identified in relation to violent outcome. Violent women were found to be more costly to services. Conclusions Nearly a fifth of community-dwelling women with chronic psychosis committed assault over a period of 2 years. Six independent risk factors were found to predict violence.
