The purpose of this study was to determine whether certain self-discrepancies predicted the extent to which individuals experienced suicidal ideation. The Selves Questionnaire (an idiographic measure of self-beliefs) was administered to 152 undergraduate participants, who also completed measures of hopelessness, depression, and suicidal ideation. Three kinds of self-discrepancies were associated with suicidal ideation: actual:ideal, actual:ought, and actual:ideal:future. Covariance structure analyses indicated a best-fitting model suggesting that, actual:ideal and actual:ideal:future self-discrepancies contribute to hopelessness, which in turn contributes to depression and suicidal (...) ideation. The findings suggest that self-discrepancy, as a form of negative self-evaluation, may contribute to an individual's risk for suicidal ideation. Moreover, the findings point to an integration of self-discrepancy theory with hopelessness theory. (shrink)

This commentary examines the implications of the Depue & Collins model for the etiology and treatment of depression, specifically, whether it can account for findings concerning neurobiological, behavioral, and phenomenological facets of depression. Drawing upon the construct of self-regulation, I explore the fit of the model to current knowledge about depression, conceptualized as a dysfunction within a hypothetical brain/behavior system for maximizing positive outcomes.
