The studies were both undertaken by the authors and used information present in databases held by the police and the courts. Finally, they examine what role behavioral analysis of rape provides and how the behavioral profile found in the study differs from that which is described from members of the community who have experienced rape firsthand. The first study they examined used data gathered from the police records of the Victoria Police on perpetrators of sexual assault on adult women. In total, information was gathered on 130 men who were charged with the crime. These records include the responses to a 263 question survey which is used to track violent crimes in Australia. The study used the responses from 28 of these questions which focused on the behavioral characteristics of rapists. All of the men whose information had been used had been charged within the previous 12 months. The second study that the authors examined used transcripts from court cases that had occurred within the past five years. A total of 50 transcripts were used, and these represented men accused of sexual assault of an adult woman.
In both cases the studies were non-experimental and as a consequence there was no independent and dependent variables as traditionally described in experimental procedures. Rather, the behavior of the offender and the relationship between the offender and the victim could be considered dependent, while the individual offenders constitute independent variables. Five behavioral themes were examined throughout the two studies, and the prevalence of these in each of the cases was examined. The themes were: brutal or physical, oral, vaginal, kissing or fondling and anal. These were determined by examination of the questions used in the survey for the first study and what the common themes were. The authors found that the most
