The authors studied some traits of social adaptation in 92 patients with involutional depressions. It was established that the level of social adaptation in the majority of patients with involutional depression (46 cases) correlates with the affect during psychopharmacotherapy, expressed in an alleviation of psychopathological disturbances, with an eventual transition of depressions to a pseudoneurotic level. In such cases there was significant improvement of adaptation. Only in 5 cases, despite the treatement there was an expressed drop of social adaptation on the background of a formed stereotyped "frozen" melancholic state.
