The frequency and effect on outcome of different types of interpretation in psychodynamic and cognitive-behavioral...

The therapeutic effects of interpretations by both therapists and other clients were recorded by observers in three cognitive-behavioral and three psychodynamic groups over a period of thirty one-and-one-half-hour group therapy sessions. There was no significant difference in the overall frequency of interpretations made in the two different therapy modalities; however, there was the expected difference in the types of interpretations made. Cognitive-behavior therapists and group members tended to interpret patterns of behavior or impact on others more frequently than did psychodynamic therapists and group members; while psychodynamic therapists and group members made more historical cause interpretations. However, contrary to expectations, both therapy modalities made more interpretations of patterns of present behavior than any other type. When these interpretations were converted into problem statements that were sent to outside raters after the termination of the groups, the outside raters judged that clients improved most when interpretations of a pattern of behavior were made; next most when interpretations of impact on others were made; and did not improve when interpretations of motive were employed in either modality.
