Bm. Dykman, NEGATIVE SELF-EVALUATIONS AMONG DYSPHORIC COLLEGE-STUDENTS - A DIFFERENCE IN DEGREE OR KIND, Cognitive therapy and research, 20(5), 1996, pp. 445-464
The tendency to engage in globally negative self-evaluations (i.e., ov
ergeneralization) is quite prevalent in depression but the precise nat
ure of this tendency is little understood. This research examined whet
her the self-evaluations of dysphoric individuals differed in ''degree
'' or ''kind'' from those of nondysphoric individuals. Dysphoric and n
ondysphoric students imagined themselves in various hypothetical situa
tions and rated how they would evaluate themselves an 49 trait dimensi
ons that varied in globality. Subjects also rated how depressed or hap
py each situation would make them feel. Subjects then estimated how th
ey would feel and evaluate themselves 3 days after the original negati
ve events. Results showed that the self-evaluations of dysphoric and n
ondysphoric subjects differed in both degree and kind. That is, dyspho
ric subjects rated themselves more negatively than nondysphorics acros
s both global and specific traits, but this negativity was particularl
y pronounced for global traits. Moreover; supporting the position that
globally negative self-evaluations influence the persistence of a dep
ressive episode, globally negative thinking by dysphoric subjects pred
icted their estimated mood 3 days after the imagined negative events,
as well as predicting their actual recovery from depression over the c
ourse of a 5-week period. Results are discussed as supporting Teasdale
's (1988) differential activation hypothesis regarding the onset and p
ersistence of depression.
