This study examines whether change in dynamic risk factors and other treatment targets over the course of violent offender treatment is associated with a reduction in violent recidivism. Data from 82 adult male violent offenders who attended a prison-based violence treatment programme were collected via retrospective file review. Therapeutic change was assessed by comparing pre- and post-treatment Violence Risk Scale (VRS) scores, ratings of denial and minimisation of violence, level of victim awareness, and motivation to change. Completion of offender treatment is found to be associated with significant change on all proximal outcome measures (i.e. reduction in dynamic risk and minimisation of violence, and increased victim empathy). However, these changes do not translate into reductions in reoffending; only one measure of within-treatment change - enhancement of victim awareness - is (negatively) associated with recidivism. These results suggest that caution is required when considering the impact of change in a restricted range of treatment targets on violent recidivism. Future research should focus on identifying reliable indicators of within-treatment change to aid idiographic assessments of violence risk and to elucidate mechanism of change.
本研究探讨暴力罪犯治疗过程中动态风险因素及其他治疗目标的变化是否与暴力再犯率的降低相关。通过回顾性档案审查,收集了82名参加监狱暴力治疗项目的成年男性暴力罪犯的数据。通过比较治疗前后的暴力风险量表(VRS)得分、对暴力的否认和淡化程度、受害者意识水平以及改变动机来评估治疗变化。结果发现,罪犯治疗的完成与所有近端结果指标的显著变化相关(即动态风险降低、暴力淡化以及受害者同理心增强)。然而,这些变化并未转化为再犯率的降低;治疗过程中变化的唯一指标——受害者意识的增强——与再犯率(呈负)相关。这些结果表明,在考虑有限范围内治疗目标的变化对暴力再犯的影响时需要谨慎。未来的研究应侧重于确定治疗过程中变化的可靠指标,以辅助对暴力风险的个性化评估并阐明变化机制。
