Development and Validation of the Satisfaction with the Intervention for Intimate Partner Violence Perpetrators Scale (SIIPVS)

Abstract Purpose Although research in the intimate partner violence (IPV) field has significantly advanced in recent decades, important challenges remain in intervention effectiveness terms. Some authors point out that satisfaction with intervention could be an indicator of effectiveness. However, this variable has not been thoroughly explored in the scientific literature. This study aimed to develop and validate a scale to measure the satisfaction with the intervention of participants attending an intervention program for IPV perpetrators. Methods A panel of experts developed the Satisfaction with the Intervention for Intimate Partner Violence Perpetrators Scale (SIIPVS) items. A sample of 646 male perpetrators was employed. Exploratory and confirmatory factor analyses, and a reliability analysis, were conducted. Scale validity was examined in relation to other relevant variables to the intervention, such as recidivism, working alliance, motivation to change and state of change. Results The findings indicate that the factor structure with the best fit consisted of three factors: Satisfaction with the facilitators and program delivery, Satisfaction with the learning-process, and Satisfaction with the peer group. All the factors demonstrated adequate internal consistency. Participant satisfaction with various intervention elements was associated with the key variables of these interventions. Conclusions The validation analysis results indicated that the SIIPVS is a suitable scale to analyze the satisfaction of the participants attending an intervention program for IPV perpetrators due to its adequate psychometric properties. Understanding participant satisfaction could provide a more comprehensive approach to evaluate the effectiveness of these interventions.
