Abstract

BACKGROUND: Recent work suggests that the social component of anhedonia is more associated with suicide ideation than the other component of pleasure. The present study investigated the differential effects of state and trait social anhedonia on suicidal ideation across two undergraduate samples based on the Interpersonal Theory and Three-Step Theory of Suicide.

METHODS: State social anhedonia was assessed with a single item (Loss of Interest in People) extracted from the Beck Depression Inventory, while trait social anhedonia was assessed using the Anticipatory and Consummatory Interpersonal Pleasure Scale. Suicidal ideation was re-administered at a 3-month follow-up.

RESULTS: In Study 1, higher state social anhedonia was associated with greater levels of suicidal ideation, while trait social anhedonia moderated the relationship between thwarted belongingness, perceived burdensomeness and suicidal ideation. In Study 2, state social anhedonia was margin significant predictor of suicidal ideation, while trait social anhedonia moderated the relationship between psychological pain and suicidal ideation.

CONCLUSIONS: These findings confirmed the presence of two different effects on suicidal ideation in state and trait social anhedonia: state social anhedonia directly was associated with suicidal ideation, while trait social anhedonia was indirectly related through their effects on other risk factors of suicidality.
