More than one way home- Student raters' impressions of interventions and group processes in mentalisation based group psychotherapy and group analytic psychotherapy

In a study comparing mentalisation-based group therapy (MBT-G) and group analytic psychotherapy (GAP) in a day clinic, both group psychotherapy forms were found to be highly effective. But how did specific interventions and processes in both groups differ? The present article describes student raters impressions. Twelve psychology students listened to 100 audio recordings of 90 minutes group psychotherapy sessions of GAP and MBT-G. Each session was randomly assigned to two student raters, who were asked to write down their impressions. These were analysed. Group conductors in MBT-G used more ques-tions, had short shares of speech, used group dynamics and fos-tered multiple perspectives on issues discussed. Affect perception was stimulated by asking questions. In PDGT, con-ductors used more interpretations, confrontations and supportive interventions, and they had longer shared of speech. Handling of affects was based on 'allowing to get infected'. Discussion. It is hypothesized that symptom reduction in both groups oc-curred via different ways: in GAP the pathic (affective conta-gion) function of interactions was more relevant, while in MBT-G it was the phatic (contact keeping) function. Results are also discussed in relation to previous findings on group processes and interventions
