A test of the hopelessness theory of depression in youth psychiatric inpatients.

Evaluated the hopelessness theory of depression among youth psychiatric inpatients. According to the hopelessness theory of depression, negative attributional style may cross-sectionally relate to an array of psychopathological symptoms. However, in the presence but not the absence of negative life events, negative attributional style relates to the onset and exacerbation of depressive (not other) symptoms. Moreover, negative attributional style relates to depression onset or exacerbation specifically via changes in hopelessness (not other mediators). This study of 60 youth psychiatric inpatients (22 boys and 38 girls; ages 9 to 17, M = 14.33, SD = 1.86), 34 of whom were assessed 2 months after leaving the hospital, tested hopelessness theory. At baseline, participants completed self-report questionnaires on attributional style, hopelessness, self-esteem, depression, and anxiety; at follow-up, questionnaires on negative life events and symptoms were completed. Chart diagnoses were available. Results were consistent with all hypotheses derived from hopelessness theory.
