It has been proposed that domestic violence offenders can be classified into distinct subgroups based on psychopathology and generality and severity of violence. This study examined a clinical sample of batterers to identify whether there were differences across batterer subtypes in regard to treatment completion, immediate treatment response, and recidivism. Indices of pathology, partner violence, and generalized violence were used to cluster analyze a sample of 175 batterers. The resulting three-cluster solution produced three different groups of batterers identified as generally violent/antisocial, borderline/ dysphoric, and family-only batterers. Results suggest that there are differences in treatment-related variables across batterer subtypes but that these differences also depend on the specific outcome variables and are not always consistent.

The ways that Iowa farm operators and extension educators perceive potential hazards in agricultural operations significantly affects the potential for behavioral change. Data gathered through separate surveys of farm operators and extension educators in Iowa were compared with agricultural injury and fatality data collected by the Iowa Department of Public Health's SPRAINS project. Statewide results indicated that educators' and operators' perceptions about farm dangers did not correspond to each other and their perceptions did not correspond to the injury records. Results indicated that although many educators and operators in some regions of the state have similar perceptions about farm dangers, their perceptions do not agree with actual injury records. The analysis provides insight into the management of future efforts to promote safety education and to bring about behavioral changes that can reduce risks.
