Abstract: | Few studies have examined the relation between depressive vulnerability factors and the duration of symptom disturbance, defined as the length of time during which mood states are elevated above a certain threshold. We examined the duration of mood disturbances in male (N=31) and female (N=71) college-aged individuals who completed mood checklists twice weekly for 10 weeks. Results showed that dependency and self-criticism were related to the mean severity of ratings across all checklists and the mean duration of disturbances, as well as the number of disturbances lasting at least 7 or 14 days. Some evidence for the congruency model was found. Dependency and self-criticism moderated the relation between vulnerability congruent hassles and mood. Sensitivity analyses showed that altering the threshold at which symptom scores were designated as symptom disturbances did not affect the pattern of results for dependency and self-criticism. Results have implications for the debate concerning the relation between vulnerability factors and depressive severity. |
