Treatment compliance and motivation to change are among the main challenges to improving batterer intervention program (BIP) effectiveness. This study examined whether adding an individualized motivational plan (IMP) to a standard BIP (SBIP) increased intervention effectiveness relative to BIP alone.
One hundred sixty males convicted of intimate partner violence were randomly assigned to receive 70 hr of either SBIP or SBIP plus IMP. The IMP is based on motivational interviewing, stages of change, and strength-based theory principles. We collected the data at baseline, at the end of the 9-month program and at 6-month follow-up. Final outcome was recidivism (recidivism data obtained from official databases, self-reported recidivism, and therapists' assessment of recidivism risk), and proximal outcomes included treatment compliance (dropout and intervention dose), and stage of change. We analyzed the results using both intent-to-treat (ITT) and per-protocol (PP) approaches.
Findings indicated that the SBIP plus IMP participants received significantly more intervention dose (R² = .08), finished the intervention in a more advanced stage of change (ITT, R² = .17; PP, R² = .22), reported less physical violence after treatment (ITT, odds ratio = .63; PP, odds ratio = .34), and had a higher reduction in recidivism risk (ITT, R² = .64; PP, R² = .56) than SBIP participants.
These results highlight the relevance of alternative approaches, including strategies to increase treatment compliance and motivation for change, in BIPs. (PsycINFO Database Record
治疗依从性和改变动机是提高施虐者干预项目(BIP)效果的主要挑战之一。本研究考察了在标准 BIP(SBIP)中添加个体化动机计划(IMP)是否相对于单独 BIP 提高了干预效果。
160 名因亲密伴侣暴力而被定罪的男性被随机分配接受 70 小时的 SBIP 或 SBIP 加 IMP。IMP 基于动机访谈、改变阶段和基于优势的理论原则。我们在基线、9 个月项目结束时和 6 个月随访时收集数据。最终结果是累犯(累犯数据从官方数据库、自我报告的累犯和治疗师评估的累犯风险中获得),近端结果包括治疗依从性(辍学和干预剂量)和改变阶段。我们使用意向治疗(ITT)和方案(PP)方法分析了结果。
研究结果表明,SBIP 加 IMP 参与者接受了显著更多的干预剂量(R² =.08),在更高级的改变阶段完成了干预(ITT,R² =.17;PP,R² =.22),在治疗后报告的身体暴力较少(ITT,优势比=.63;PP,优势比=.34),累犯风险降低幅度更大(ITT,R² =.64;PP,R² =.56)比 SBIP 参与者。
这些结果强调了替代方法的相关性,包括增加治疗依从性和改变动机的策略,在 BIP 中。
