Motivational Strategies in Batterer Intervention Programs for Offenders With Alcohol/Drug Abuse Problems (IMP-ADAPs) (IMP-ADAPs)

Motivational Strategies in Batterer Intervention Programs for Intimate Partner Violence Offenders With Alcohol/Drug Abuse Problems: An Experimental Study

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: SBIP+ ADAPs-IMP; Experimental condition: Standard batterer intervention program (SBIP) plus individualized motivational plan (IMP) focused in alcohol and/or drugs abuse problems (ADAPs).	Behavioral: SBIP+ ADAPs-IMP; Standard batterer intervention program plus Individualized Motivational Plans adapted to alcohol and/or drug abuse problems. The SBIP consist of 70 hr of a cognitive-behavioral intervention including discussion topics such as sexism, sex roles, and gender equality. The intervention phase consisted of six modules in which different intervention techniques were applied (i.e., group dynamics, roleplaying, videos, training in cognitive restructuring, emotion management skills). The IMP included a set of motivational strategies to increase treatment compliance and motivation for change and had four main strategies: (a) five individual motivational interviews, to identify IPV related personal goals and follow up their achievement (in this case, one of the goals has to be related to ADAPs); (b) three group sessions where participants share their goals; (c) therapists follow-up and reinforcement of participants' goals; and (d) use of retention techniques.
