Joiner’s (2005) interpersonal-psychological theory of suicidal behaviour proposes an individual will not die by suicide unless he or she has both the desire to & the ability to do so. 3 studies tested these hypotheses. In Study 1, the interaction of thwarted belongingness & perceived burdensomeness predicted current suicide ideation. In Study 2, greater levels of acquired capability were found among individuals with greater numbers of past attempts. Painful & provocative experiences significantly predicted acquired capability scores. In Study 3, the interaction of acquired capability & perceived burdensomeness predicted clinician-rated risk for suicidal behaviour. (42 refs.)
