Abstract

This study examined the impact of an intensive inpatient violent offender treatment programme, Life Minus Violence-Enhanced (LMV-E), on intermediary treatment targets, risk for violence, and aggressive behaviour during treatment in a sample of male mentally disordered offenders. Using quasi-experimental design, offenders who completed LMV-E and a comparison group showed reduced problems with impulsivity and anger regulation and improvements in social problem solving. Aggregate risk for future violence lessened in both treatment and comparison groups, although by a significantly greater degree for the comparison group. The aggressive behaviour of both groups reduced. Completion of the LMV-E conferred additional improvements in some facets of social problem solving and anger regulation. Neither group showed improvements in empathic responses, coping skills or problematic interpersonal style. Overall, these results suggest anger regulation, impulsivity and social problem solving are most amenable to change, that reductions in certain facets of these dynamic risk factors transpires with nonspecific psychiatric inpatient treatment, but that the LMV-E, a cognitive behavioural violence specific psychological treatment, confers greater change in some facets of social problem solving and anger regulation.
