Life Minus Violence-Enhanced (LMV-E) with women in custody: single-case experimental design

Abstract

Purpose

The purpose of this single-case experimental design paper is to examine the efficacy of the high-dosage Life Minus Violence – Enhanced (LMV-E) programme with a small sample of four violent women in custody. All participants were undertaking LMV-E as one component of their treatment pathway in an Offender Personality Disorder (OPD) treatment service for women with personality disorder. The methodology employed an AB baseline design with a six-month baseline period, nine-month treatment period and six-month follow-up. Levels of direct and indirect aggression were recorded throughout the baseline, intervention, and follow-up period. In the follow-up period, women were engaging in further treatment. Psychometric measures linked to treatment domains were used to explore clinically significant and reliable change following the intervention. Clinical and reliable change was indicated in some treatment domains for each participant following the intervention. The pattern of these reductions varied between the women. The patterns of findings are discussed and recommendations presented.

Design/methodology/approach

The methodology employed an AB baseline design with a six-month baseline period, nine-month treatment period and six-month follow-up. Levels of direct and indirect aggression were recorded throughout the baseline, intervention and follow-up period. In the follow-up period, women were engaging in further treatment. Psychometric measures linked to treatment domains were used to explore clinically significant and reliable change following the intervention.

Findings

Clinical and reliable change was indicated in some treatment domains for each participant following the intervention. The pattern of these reductions varied between the female offenders. The patterns of findings are discussed and recommendations presented.

Practical implications

The LMV-E programme was associated with some positive improvements in treatment domains measured in a small sample of female violent offenders. Improvements to some degree were most commonly found in the domains of anger, emotional control and components of criminal thinking. It would be clinically useful to examine characteristics of individuals that appear to benefit most from particular interventions.

Originality/value

There are no existing published findings related to the implementation of LMV-E with females. Therefore, this paper provides preliminary contribution to the evidence base in this area.
