Treatment utility of the sociotropy/autonomy distinction: implications for cognitive therapy

The treatment utility of the Sociotropy/Autonomy Scale was evaluated by matching or mismatching subjects to either individual or group cognitive therapy according to their dominant personality dimension. Both groups of subjects obtained statistically significant, but equivalent, reductions in depression. Consistent with Beck's (1983) interactional model, tests of clinical significance indicated a higher proportion of matched subjects who displayed marked improvement at follow-up. Implications for cognitive therapy and further research on the assessment of personality dimensions relevant to depression are discussed.
