This thesis sought to address critical gaps in the literature on the interpersonal theory of suicide. First, three core assumptions regarding the theory's two putative causes of suicidal desire, perceived burdensomeness and thwarted belongingness, were tested experimentally. Key predictions about the theory's third pillar, the acquired capability for suicide, in transforming suicidal thoughts into lethal behavior were next examined longitudinally. Finally, the protective influence of zest for life was tested against the adverse effects of the theory's three risk factors. Findings support key predictions of the theory though some modifications to the model are indicated.
