title: Examining the unique relations between anxiety sensitivity factors and suicidal ideation and past suicide attempts.
abstract: Anxiety sensitivity (AS) has recently been linked to suicidality. Specifically, AS cognitive concerns has been implicated as a risk factor, and AS physical concerns as a protective factor, for suicidal ideation and suicide attempts. However, no studies have used structural equation modeling (SEM) to address issues of skewed suicide variables and bifactor modeling of AS to address the high degree of overlap between the lower-order dimensions of AS that limit interpretation of these past findings. AS, suicidal ideation, past suicide attempts, and depression were assessed in a clinical sample of 267 individuals (M age=35.45 years, SD=16.53; 52.1% female). The global AS and AS cognitive concerns factors were positively, significantly associated with suicidal ideation, though these effects were nonsignificant controlling for depression. The global AS factor was positively, significantly associated with suicide attempts, controlling for depression. The current study demonstrated that the relations between AS and suicidal ideation are not maintained when accounting for depression, suggesting that the relation between AS and suicidal ideation may be mediated by depression. The positive relation between global AS and suicide attempts is consistent with theories positing suicide attempts as a consequence of an inability to cope with intolerable distress.
