Given ID:p0310 the research on IPV that shows relatively high rates of mental health issues and substance use among perpetrators (Bell & Orcutt, 2009;Brasfield et al., 2012;Lipsky et al., 2005;Moore & Stuart, 2004;Rhodes et al., 2009;Shorey et al., 2012;Stuart et al., 2008), it is not surprising that we found a high overlap between IPV perpetration and mental health, and drug and alcohol issues.

In general, this research has found positive outcomes in terms of reductions of abusive behaviors, and underscored the need to offer substance use treatment alongside batterer intervention (Easton et al., 2007;Goldkamp et al., 1996;Gondolf, 1999;O'Farrell et al., 2004;Schumacher et al., 2003;Stuart et al., 2003). ...
