Men court-mandated to attend a batterer's intervention program (BIP) were evaluated to determine whether pre-BIP readiness to change and the presence of partner violence subtypes predicted BIP completion, criminal recidivism, and postadjudication partner violence 6 months post-BIP. Of the 199 subject sample, 40% did not complete BIP. Four readiness-to-change clusters were found, with most men (76%) reporting change-resistant stages-of-change profiles. The partner violence typology reported by Holtzworth-Munroe et al. (2000) was supported with clustering into four subtypes: family only (FO), low-level antisocial (LLA), borderline/dysphoric (BD), and generally violent/antisocial (GVA). BIP completion was predicted by violence subtype (with BD and GVA more likely to drop out) but not by pre-BIP readiness to change. Men rearrested scored higher on the precontemplative stage of change and were more likely to be in the BD and GVA subtypes. Implications for counseling strategies are discussed.
