Description

The Interpersonal Theory of Suicide (ITS) is one of the most intensively researched contemporary theories on the development of suicidal ideation and behavior. However, there is a lack of carefully conducted prospective studies. The project aimed to evaluate the main predictions of the ITS regarding the importance of perceived burdensomeness, thwarted belongingness, and capability for suicide in predicting future suicide attempts in a prospective design. In  total N=308 psychiatric inpatients admitted due to severe suicidal ideation or a suicide attempt completed self-report measures as well as interviews on suicide intent and suicide attempts and were followed up for 12 months. The interaction of PB, TB and CS was not predictive for future suicide attempts. The results challenge the theoretical validity of the ITS and its clinical utility – at least within the methodological limitations of the current study.
