In the present study, RA was associated with attempted suicide in the univariate test and showed nonsignificant but trend level associations in the multivariate models before (p=.17) and after (p<.10) inclusion of the sex by PA interaction term. Given these results, in which other variables appear to have accounted for a portion of the association between RA and suicide attempts, it would be premature to dismiss the role of RA in attempt among individuals with substance dependence. Interestingly, the data support that RA is relevant to ideation among individuals with substance dependence, a question on which there are meager data. Thus, RA may contribute to suicidality broadly, insofar as suicide-related cognitions are more prevalent than suicidal behavior and may be assumed to precede such behavior (Conner et al., 2007a; Kessler et al., 1999).
