Effect of time-limited psychotherapy on patient dropout rates.

The authors conducted an archival study of 149 new clinic patients at a large community mental health center. The dropout rate for patients in brief psychotherapy in which the length of therapy was specified at the outset of treatment (time-limited psychotherapy) (32%) was about one-half the dropout rate for patients in brief (67%) and long-term (61%) individual psychotherapy. The difference in dropout rates could not be explained by patient demographic or diagnostic variables or by therapist characteristics measured in the study. The results suggest that setting a specific time limit on individual psychotherapy at the outset of treatment can reduce the patient dropout rate in a public mental health clinic.
