title: Evidence for the Propositions of the Interpersonal Theory of Suicide Among a Military Sample.
abstract: OBJECTIVE
  Although the interpersonal theory of suicide may explain the elevated suicide risk among military service members, past explorations have been equivocal. This study aimed to investigate the propositions of the interpersonal theory in a sample of U.S. Army recruiters.
  
  
  METHODS
  Participants (N = 3,428) completed self-report measures assessing the interpersonal theory's constructs (i.e., thwarted belongingness (TB), perceived burdensomeness (PB), acquired capability for suicide), current suicidal ideation, agitation, and insomnia. History of depression was obtained from medical records.
  
  
  RESULTS
  Hierarchical multiple regression analyses revealed that the interaction between TB and PB was associated with current suicidal ideation, controlling for depression, agitation, and insomnia. This effect was especially notable among those with high capability for suicide.
  
  
  CONCLUSIONS
  Findings provide support for the interpersonal theory in a large, diverse military sample. It may be advantageous to assess and therapeutically address TB and PB among at-risk service members.
