Enhanced Adaptive Capacities After Brief Treatment for Depression

Using data from the National Institute of Mental Health-sponsored Treatment of Depression Collaborative Research Program, the authors examined predictors of the intensity of depressive symptoms after the brief treatment of depression. Multilevel modeling was applied to measures of depression and stress assessed at termination and at 6-, 12-, and 18-month follow-ups. The slope of depression on stress was used to index stress reactivity. Patients with high mean levels of stress experienced more intense depressive symptoms, but this effect was moderated by patients' reports of the extent to which they had acquired enhanced adaptive capacities (EACs) in treatment. Patients who reported high EAC early in the follow-up were more resilient in the face of stress than those with low EAC. Greater EACs were found for patients who received psychotherapy than medication or placebo and, across all treatments, for patients with a stronger therapeutic alliance. These findings suggest that treatments should be evaluated in terms of their impact on patients' developing adaptive capacities as well as the reduction of symptomatology.
