title: Improving experience in personal social systems through family constellation seminars: results of a randomized controlled trial.
abstract: This study examined the efficacy of family constellation seminars (FCSs) on individuals' experience in their personal social systems, especially the experience of belonging, autonomy, accord, and confidence. We conducted a single-blind, stratified and balanced, randomized controlled trial. Participants were 208 adults (M = 48 years, SD = 10, 79% women) who were randomly allocated either to the intervention group (3-day FCSs; 64 active participants, 40 observing participants) or to the wait-list group (64 active participants, 40 observing participants). Change was measured short-term (2-week and 4-month follow-up) using the Experience In Social Systems Questionnaire, personal domain (EXIS.pers). EXIS.pers is a new outcome measure being applied for the first time in evaluation research. In addition, we used interpersonal scales derived from established measures (Outcome Questionnaire, OQ-45; Tool for the Evaluation of the Psychotherapeutic Progress, FEP). The average person in the intervention group showed improved experience in personal social systems, as compared with approximately 73% of the wait-list group after 2 weeks (total score: Cohen's d = .61, p = .000) and 69% of the wait-list group after 4 months (total score: d = .53, p = .000). The results were confirmed in per-protocol analyses (n = 191) by the results of the EXIS.pers dimensions (Belonging, Autonomy, Accord, and Confidence) and the interpersonal scales derived from the OQ-45 and FEP. No adverse events were reported. This RCT provides first evidence that FCSs tend to positively influence participants' experience in their social systems.
