“…Our ST is mostly based and inspired by the work of Helm Stierlin and colleagues during the early 1980s, which has since continued to be refined and is comprehensively described in von Schlippe and Schweitzer (2012) and Hunger, Hilzinger and Schweitzer (2016). It integrates concepts and practices from post‐Milan circular interviewing and questioning to fluidize the presented symptoms (Boscolo, Cecchin, Hoffmann, & Penn, 1987; Penn, 1982), solution‐focused language and restoration of a dominant problem‐saturated narrative, externalization of symptoms based on the narrative‐solutions approach (de Shazer et al., 1986; Lund, Eron, & Dagirmanjian, 2016), genogram interviewing (Petry & McGoldrick, 2013) and symbolic action methods like sculpting (Duhl, Kantor, & Duhl, 1973) a variation of systems constellations which have been found to be effect in another RCT (Hunger, Weinhold, et al, 2015; Hunger, Bornhäuser, Link, Schweitzer, et al, 2014; Weinhold et al, 2013). Theoretically, it is grounded in communication (Watzlawick, Weakland, & Fisch, 1969) and social systems (Luhmann, 2017) theory, with strong ties to the autopoiesis concept (Maturana & Varela, 1987).…”
