Webinar Details:

Recent reviews of evaluations of domestic violence and abuse (DVA) perpetrator programmes in Europe highlighted variations in the methodological designs used to evaluate programmes, as well as a myriad of quantitative tools to measure outcomes (Akoensi et al., 2013; Hester et al., 2014). The inconsistencies across design and measures limited the conclusions that could be drawn about the effectiveness of programmes. The IMPACT Project - Evaluation of European Perpetrator Programmes developed The Toolkit, in an effort to harmonise the methods and tools used. The starting point for developing The Toolkit was the survey Comparing Heterosexual and Same-sex Abuse in Relationships (COHSAR; Hester & Donovan 2009; Hester, Donovan & Fahmy, 2010; McCarry, Hester and Donovan, 2008). The authors of COHSAR developed a survey that was sensitive to gender and power dynamics, captured a range of DVA behaviours and took into account the context and consequences of DVA. COHSAR provided not only the type of information commonly reported by the Conflict Tactics Scales (CTS – 2; Straus et al., 1996) but also information necessary to address the substantial critiques of the CTS – 2 (e.g. Dobash et al., 1992). In the webinar, the development and content of COHSAR will be reviewed first followed by a discussion of how COHSAR was adapted for The Toolkit.
