Although batterers' intervention programs (BIPs) constitute an important part of the coordinated response to intimate partner violence (IPV) and contribute to increasing the perpetrators' accountability and keeping victims safe, the effectiveness of these programs is still debated. Only recently has the focus of these debates shifted away from researching outcomes by measuring overall program effectiveness toward specific qualities of interventions across program models that may be effective for the distinct client (Babcock et al., Clinical Psychology Review, 23(8), 1023-1053, 2004; Zarling et al., Psychology of Violence, 9(3), 257-266, 2019). The discussion on the practical implementation of BIPs was supplemented by various significant concepts emerging from new empirical findings, such as differential treatment, motivational interviewing, and effective facilitator-client alliances (Hamel et al., Partner Abuse, 11(4), 387-414, 2020; Holtrop et al., Journal of Interpersonal Violence, 32(8), 1267-1290, 2017). This paper aimed to address some of the abovementioned concepts by identifying challenges that arise during the implementation of BIPs in Lithuania. Using qualitative data from semi-structured interviews and focus group discussions with BIPs facilitators, BIPs attendees, and various stakeholders, the paper discusses how to contribute to more effective BIPs outcomes. According to this study, the process of implementing BIPs in Lithuania should be systematized by incorporating existing instruments, such as motivational interviewing, risk-based assessment, and differential treatment, evidence-based programs focused on different theoretical approaches, and forms of implementation. The study found that the consistency and integrity of the entire BIP implementation process should be prioritized, and institutional cooperation in Lithuania needs to be improved to achieve a successful coordinated response to intimate partner violence.
