Depression; Mental--Care and treatment


The time relationship between depression-associated thoughts and depressed mood was assessed by administering questionnaires every other day over the course of a psychoeducational treatment program for depression. Two groups of moderately depressed adult outpatients, an immediate treatment (IT) group (N=9) and a delayed treatment (DT) group (N=6) were examined. Of six hypotheses tested, three were supported. Almost all subjects experienced a reduction in depression following treatment. Further, that reduction was maintained at a one-month follow-up. "Explanatory style" changes occurred after the program such that participants produced fewer internal, stable and global explanations of negative outcomes. However, 1) depression did not appear to be alleviated more rapidly in the IT group than the DT group, as expected from past research. The small sample size and short waiting period were suggested as reasons for the failure to replicate previous results. 2) Reductions in the frequency of depressive cognitions did not precede or predict improvements in mood for the participants. It was suggested that the time interval of two days might have been too long, that the index of depression-associated cognitions may not assess cognitions which lead to depression, and that the relationship between depression—associated cognitions and mood may be reciprocal. 3) Reductions in the reported frequency of depression-associated cognitions were not specific to training in techniques to change cognitions. This finding was contrasted with that of a recent pharmacological study which found that changes in depression-associated cognitions followed a drug treatment for depression.
