Additionally, the clients in the psychoeducational groups were assessed by a GoalAttainment Scaling procedure. The clients in the experienttial groups were considered to be a conservative cotntrol group rather than a comparison group because of the length of treatment. Additionzally, clienits in both types of group completed process evaluations selected by thle therapists of both cotnditions after every session. Results inidicated that the clients in the psychoeducational groups improved significantly more than the clients in the experiential grouips ont both measures and improved on the Goal Attainment Scaling measure when compared to goals not addressed in therapy. Each condition was significantly superior on the process measures chosen by the therapists of that condition; however, factor analysis of the process and outcome data indicated the relationshtip of process to outcome was not linear and was extremely complex.
