The authors examined the follow-up data for 113 psychiatric outpatients who had been treated for up to a year in an outpatient community mental health center. Correlations between therapist and patient ratings of improvement were generally low, and anlayses were done separately for therapist and patient ratings. The strongest confirmed hypothesis was the relationship between therapist and patient ratings of improvement and therapist and patient evaluations of each other as likable, physically attractive, and either a good patient for treatment or a competent therapist. The authors discuss the advantages and disadvantages of multivariate statistics for the analysis of psychotherapy data.
