The present study expands upon the Interpersonal Psychological Theory of Suicide (IPTS), examining its relationship with the need for affect (NFA), a construct explaining attitudes toward seeking both positive and negative emotions. A sample of 576 emerging adults completed measures of NFA, IPTS, suicide proneness, and demographics online. Findings include NFA accounting for a small significant amount of suicide proneness, a positive association between approaching emotions and one indicator of suicide proneness, negative association between approaching emotions and thwarted belongingness, and positive associations between avoidance of emotions with both perceived burdensomeness and thwarted belongingness. Findings are discussed concerning NFA as a theoretically and practically relevant factor for understanding suicide.
Keywords: emotional avoidance; need for affect; perceived burdensomeness; suicide proneness; thwarted belongingness.
