Acquired capability for suicide, pain tolerance, and fearlessness of pain—validation of the pain tolerance scale of the German Capability for Suicide Questionnaire

Résumé

The interpersonal theory of suicide (Joiner, 2005) postulates that for a serious suicide attempt, one has to possess the acquired capability to commit suicide. Acquired capability includes higher pain tolerance, which is further assumed to comprise both an elevated physical pain tolerance and fearlessness of pain. Recently, the German Capability for Suicide Questionnaire (GCSQ) was validated. The aim of this study is further validation of the GCSQ's Pain Tolerance scale by investigating the scale's association with objective pain tolerance and fearlessness of pain in two undergraduate samples (N = 81; N = 76). Both associations were found indicating a strong criterion validity of the Pain Tolerance scale.
