The Experience in Personal Social Systems Questionnaire (EXIS.pers): Development and Psychometric Properties.

Mid- and long-term effects of family constellation seminars in a general population sample: 8- and 12-month follow-up.

In a previous randomized controlled trial (RCT), short-term efficacy of family constellation seminars (FCSs) in a general population sample was demonstrated. In this article, we examined mid- and long-term stability of these effects. Participants were 104 adults (M = 47 years; SD = 9; 84% female) who were part of the intervention group in the original RCT (3-day FCS; 64 active participants and 40 observing participants).

Improving experience in personal social systems through family constellation seminars: results of a randomized controlled trial.

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).

Family constellation seminars improve psychological functioning in a general population sample: results of a randomized controlled trial.

The study examined the efficacy of nonrecurring family constellation seminars on psychological health. We conducted a monocentric, single-blind, stratified, and balanced randomized controlled trial (RCT). After choosing their roles for participating in a family constellation seminar as either active participant (AP) or observing participant (OP), 208 adults (M = 48 years, SD = 10; 79% women) from the general population were randomly allocated to the intervention group (IG; 3-day family constellation seminar; 64 AP, 40 OP) or a wait-list control group (WLG; 64 AP, 40 OP).
