Using data from five Spouse Assault Replication Program (SARP) sites, this study examined the extent to which domestic violence offenders exhibit a specialized proclivity toward violence and the extent to which attack severity escalates, de-escalates, or stays about the same over time. The specialization question was examined using official arrest records from the Charlotte, North Carolina, Colorado Springs, Colorado, Milwaukee, Wisconsin, and Omaha, Nebraska sites. Escalation was examined using victim interview data from the Charlotte, Milwaukee, Omaha, and Miami-Dada, Florida sites. This collection consists of 18 SAS setup files used to recode the variables from the original datasets, organized in five groups, by city of each data collection site. This collection does not contain the original data files, themselves.
