Previous research findings have shown that suicide rates have significantly increased within the past few years in Mexico. However, there is a limited amount of evidence available regarding suicidal behaviors in Mexico. The main purpose of the present study is to (1) identify who is at risk of experiencing suicidal ideation, (2) examine the generalizability of the model proposed by the interpersonal theory of suicide to other cultures, and (3) examine the relationship between depression, hopelessness, interpersonal needs, and the acquired capability to die regarding suicidal behaviors, as dictated by the interpersonal theory of suicide in an inpatient adult sample in Mexico. A total of 199 adults receiving inpatient treatment for substance use participated in the present study. The participants completed a survey packet of self-report questionnaires in a paper-pencil format. The survey included the Personal Resources Questionnaire (PRQ-85; Weinert, 1987), the Beck Hopelessness Scale (BHS; Beck et al., 1974), the Beck Depression Inventory-II (BDI-II; Beck, Steer & Brown, 1996), the Interpersonal Needs Questionnaire (INQ; Van Orden et al., 2008), the Acquired Capacity for Suicide Scale (ACSS; Van Orden et. al., 2008), and the Suicide Behaviors Questionnaire-Revised (SBQ-R; Osman et al., 2001). The findings showed that depression, hopelessness, thwarted belongingness, and perceived burdensomeness had a significant association with suicidal behaviors. On the other hand, social support had a significant negative association with suicidal behaviors. Additionally, the acquired capacity to die was not associated with suicidal behaviors. Two hierarchical regressions were conducted to further examine these relationships. The results revealed that the interaction between the interpersonal needs did not predict suicidal ideation. However, the main effects for depression were significant predictors of suicidal ideation. In the second set of analyses, the interaction between perc (open full item for complete abstract)
