Abstract

Interpersonal needs are associated with suicide. However, no interpersonal needs questionnaire has been validated in Asia. The psychometric properties of the Interpersonal Needs Questionnaire were examined in a sample of 340 young male adults in Singapore. This questionnaire measures proximal causes of desire for suicide using the extent to which individuals believe that they are a burden to others (perceived burdensomeness) and the extent to which they believe their needs are not met (thwarted belongingness). Confirmatory factor analysis found that a two-factor model of perceived burdensomeness and thwarted belongingness provided an adequate fit for the data. Internal consistency was excellent. Concurrent, convergent, predictive, and discriminant validity was demonstrated. The findings showed that the Interpersonal Needs Questionnaire provides a valid measure of interpersonal needs in young Asian males. Thus, the instrument can be utilized to test the interpersonal psychological theory of suicidal behavior.
