Frequency of treatment and change in psychotherapy.

To test the hypothesis that frequency of weekly interview has a selective effect on psychological changes in patients in individual psychotherapy, 133 VA outpatients were randomly assigned to 3 schedules: twice, once, and bi-weekly. Changes were measured by tests based on objective evaluation of personality characteristics and assessed after 4 mo., 8 mo., and 12 mo. of therapy. The results failed to confirm that there was any major support for the hypothesis that frequency of contact produced differences in personality changes.
