Entrapment, perceived burdensomeness and thwarted belongingness as predictors of suicide ideation.

The Integrated Motivational-Volitional (IMV) Model of suicide posits that perceived burdensomeness and thwarted belongingness moderate the association between perceptions of entrapment and suicide ideation. However, the proposed moderation is yet to be tested. Possible moderator effects were investigated in an online sample (N = 480; 74% female; Mage = 28.5, SDage = 11.1). Entrapment and perceived burdensomeness predicted suicide ideation. However, neither perceived burdensomeness nor thwarted belongingness moderated the association between entrapment and suicide ideation. The present results do not support a key assumption of the IMV-Model. Nonetheless, they underscore the importance of perceived burdensomeness and entrapment in the prediction of suicide ideation.
