By design, participants in the community-based sample were not excluded based on drug dependence and subsequently 19% (n=87) of these individuals met criteria for cocaine dependence. In addition, 71.3% of the cocaine dependent community-based sample (n=62) sought chemical dependency treatment. In part, the high prevalence of traumatic events experienced by the community cohort may be related to these cocaine dependent community participants. To address this, analyses were repeated with the community-based cohort separated into two groups: cocaine dependent and non-cocaine dependent. The cocaine dependent community-based individuals reported traumatic event rates similar to the cocaine dependent individuals recruited from treatment centers and there were no statistically significant differences between the groups. Trauma exposure rates in the non-cocaine dependent community-based participants decreased; however, the comparisons to the cases were similar to those seen before (see Table 2).
