Brief Summary

Alcohol and/or drug abuse problems (ADAPs) have been consistently identified in the scientific literature as a risk factor of intimate partner violence against women (IPVAW). Around 50% of IPVAW offenders referred to batterer intervention programs (BIPs) have ADAPs. ADAPs are also one of the main predictors of BIPs dropout. In Spain, the majority of BIPs do not fit the intervention to specific needs or characteristics of IPVAW offenders, such as those with ADAPs. The aim of this research is to assess the effectiveness of a new motivational strategy adapted to IPVAW offenders with ADAPs, aiming to increase treatment adherence and to improve BIPs outcomes. The motivational strategy will include an individualized motivational plan (IMP) developed for each participant with ADAPs (IMP-ADAPs). In these IMPs one of the main aims will be to reduce alcohol and/or drug consumption. The current study will use a randomized control trial. Participants with ADAPs will be allocated to one of two treatment conditions: experimental condition: Standard batterer intervention program (SBIP) plus individualized motivational plan focused in ADAPs (SBIP+ ADAPs-IMP), and control condition: Standard batterer intervention program plus individualized motivational plan (SBIP+IMP). Primary/final outcomes will be recidivism and ADAPs reduction. Secondary/proximal outcomes will include treatment adherence related variables, violence related attitudes and attributions, self-control and psychological adjustment. Outcome variables will be assessed at baseline, at the end of the intervention, and at six months after the intervention will be finished.

Primary Outcome Measures

Name	Time	Method
Change in cannabis abuse problems	At baseline, at 12 months (end of intervention), and at 18 months (follow-up)	Severity Dependence Scale. Gossop et al., 1995. Total scale range: 0-15 (Higher values indicate worse outcome).
Change in cocaine abuse problems	At baseline, at 12 months (end of intervention), and at 18 months (follow-up)	Severity Dependence Scale. Gossop et al., 1995. Total scale range: 0-15 (Higher values indicate worse outcome).
Change in self-reported physical intimate partner violence against women	At baseline, at 12 months (end of intervention), and at 18 months (follow-up)	Self-reported physical violence sub-scale from the Conflict Tacticts Scale. Straus, Hamby, Boney-McCoy y Sugarman, 1996. Total scale range: 0-72 (Higher values indicate worse outcome).
Change in alcohol abuse problems	At baseline, at 12 months (end of intervention), and at 18 months (follow-up)	Alcohol Use Disorders Identification Test. Saunders, Aasland, Babor, De la Fuente, \& Grant, 1993. Total scale range: 0-20 (Higher values indicate worse outcome).
Change in self-reported psychological intimate partner violence against women	At baseline, at 12 months (end of intervention), and at 18 months (follow-up)	Self-reported psychological violence sub-scale from the Conflict Tacticts Scale. Straus, Hamby, Boney-McCoy y Sugarman, 1996. Total scale range: 0-72 (Higher values indicate worse outcome).

Police-reported recidivism	At 18 months (follow-up)	Ministry of Home Affairs' monitoring system for IPV. This system includes information on further incidents of violence by individuals convicted of IPV and reported by any of the institutions involved in victim protection services. Recidivism will be considered to have occurred when this information appear in the system in the 6 months after completing the intervention.

Secondary Outcome Measures

Name	Time	Method
