Overarousal interacts with a sense of fearlessness about death to predict suicide risk in a sample of clinical outpatients.
Ribeiro, J.~~Silva, C.~~Joiner, T.
Converging evidence suggests that acute states of overarousal are common prior to suicidal behavior. Yet, there has been very little theory-driven research of these phenomena. We consider two competing theoretical perspectives. The first is consistent with the interpersonal theory of suicide, which suggests that the prospect of engaging in lethal suicidal behavior should elicit some degree of arousal; however, the effect of arousal will be particularly relevant when considered in the context of an individual׳s capability for suicide. The second perspective draws from escape-based models, which would suggest that arousal alone should result in increased suicide risk, given the distress associated with high arousal states.
