Patient activity and outcome in group psychotherapy: new findings. 
The relation of patient verbal activity to pretherapy symptom status and outcome was examined for ninety patients in time-limited group psychotherapy.  For each half-hour segment the most verbally active member, or main actor (MA), was identified.  Verbal activity was measured by counting the number of times each patient was MA during the course of the group.  Outcome was assessed by administering a battery of instruments pre- and posttherapy and by obtaining direct ratings of patient benefit from the patient, therapist, and an independent rater: the number of times MA was found to be significantly correlated with four pretherapy measures, indicating that the most disturbed patients were most active in these groups; the number of times MA was also correlated with patient and therapist benefit ratings, indicating that therapists and patients themselves agreed that those who spoke the most benefited the most.  However, partial correlations between number of times MA and other outcome measures did not produce any significant relationships.  Thus, it does not appear that patient verbal activity is related to outcome, as measured by objective instruments.
