title: Testing the main prediction of the Interpersonal Theory of Suicide in a representative sample of the German general population.
abstract: To evaluate the main prediction of the Interpersonal Theory of Suicide (IPTS): 3-way-interaction of perceived burdensomeness (PB), thwarted belongingness (TB), and acquired capability (AC) for the prediction of suicidal behavior in a representative population sample.
  
  
  
  A total of 2513 participants completed measures of suicidal behavior, TB, PB, acquired capability (AC-FAD), and symptoms of depression and anxiety.
  
  
  
  The two-way-interaction of TB and PB, and the three-way interaction of TB, PB and AC-FAD predict suicidality.
  
  
  
  Given the cross-sectional nature of the data, conclusions on causality should be handled carefully.
  
  
  
  The main prediction of the IPTS has been proven in a general population sample.
