Patient suitability and outcome in short-term individual psychotherapy

The effects of short-term (time-limited), dynamically oriented individual therapy and the patient characteristic quality of object relations (QOR) were studied in a controlled clinical trial involving 8 experienced therapists and 144 psychiatric outpatients. A comprehensive set of outcome scores was monitored at 5-month intervals including a follow-up assessment. A strong treatment effect that was maintained at follow-up was found. The effect was evident in terms of statistical significance, effect size, and clinical significance. Evidence for an additive effect of the combination of treatment and QOR was also found. The best results were attained by high QOR therapy patients, and the worst results were attained by low QOR control patients. The results were suggestive of an optimal match between type of patient and type of therapy.
