Systems-centered training groups' process and outcome: a comparison with AGPA institute groups

In this quasi-experimental study we compared the process and outcome of six experiential Systems-Centered Training (SCT) groups to those of American Group Psychotherapy Association (AGPA) Institute groups from two prior studies (MacKenzie, Dies, Coche, Rutan, & Stone, 1987; Tschuschke & Greene, 2002). The SCT training compared well overall and the results provided preliminary, indirect support for the usefulness of "functional subgrouping" - SCT's conceptual and methodological bridge between the group-as-a-whole and the individual member. However, quasi-experimental design limitations make other interpretations equally plausible. Within-group change in the process variables for the SCT groups was also explored, as well as the relative contributions of these variables to post-training learning outcomes and anxious and depressive experience. The results partly corroborated prior studies, but also suggested that SCT may alter training group dynamics, learning, and emotional experience in ways consistent with SCT theory.
