A longitudinal investigation of information processing and cognitive organization in clinical depression: stability of schematic interconnectedness

J Consult Clin Psychol. 2001 Dec;69(6):914-25.


This study longitudinally investigated information processing and cognitive organization in clinical depression. The main hypothesis was that individuals whose depression had remitted would show a significant cognitive shift on information processing (e.g., deactivation of negative processing) but not on cognitive organizational tasks, Forty-five individuals with clinical depression completed 2 information processing and 2 cognitive organizational tasks at initial assessment. At 6-month follow-up, the sample (23 remitted, 22 stable depressed) was readministered the tasks. As expected, information processing shifted significantly in individuals who had improved symptomatically, whereas negative cognitive organizational indices remained stable. The implications of these results are discussed as they pertain to the cognitive vulnerability, maintenance, treatment, and recurrence of depression. Directions for future research are suggested.
