“…The importance of developing and maintaining such multidimensional alliances has been robustly discussed in family and couple therapy research (e.g., Friedlander et al, 2018Friedlander et al, , 2022Rait, 2000). Recent studies point to the necessity of parallel collaboration with the entire family and couple system while building therapeutic alliances (Metcalfe et al, 2021;Whittaker et al, 2022). Therefore, investigating how this complex work is done interactively, that is how the alliance is discursively and interactionally accomplished was undertaken by interactional research (e.g., Horvath & Muntigl, 2018;Muntigl & Horvath, 2016;Sutherland & Strong, 2011).…”
