In this study we examine the role that pressure to attend therapy, dyadic adjustment, and adverse childhood experiences (ACEs) play in developing the therapeutic alliance. A total of 351 couples received treatment as usual at three family therapy training clinics. Participants rated predictor variables at intake and alliance at the fourth session. Results of a path analysis indicate that each partner's dyadic adjustment is directly associated with the quality of her or his own alliance. In addition, when male partners report more ACEs and pressure to attend treatment, their own alliance scores decrease. Additionally, when one partner reports feeling pressure to attend therapy, the other partner's alliance decreases. Finally, for males, there is an indirect effect of dyadic adjustment on alliance through pressure to attend therapy. These results suggest that clinicians should routinely assess relationship adjustment, how pressured each partner is feeling to attend treatment, and ACEs; as these may impact alliance quality.
BACKGROUND AND SIGNIFICANCEThe therapeutic alliance is one of the most robust predictors of therapeutic outcomes across individual, couple, and family therapy (Barber et al., 2001;Friedlander, Escudero, Heatherington, & Diamond, 2011). A recent meta-analysis of the alliance-outcome link in couple and family therapy provides strong evidence for this relationship, with a medium effect size (d = 0.6; Friedlander, Escudero,Welmers-van de Poll, & Heatherington, 2018). Despite the importance of the alliance to successful therapeutic outcomes, we know surprisingly little about factors that predict successful alliance formation with couples. As a result of this knowledge gap, clinicians who hope to improve outcomes by improving the alliance have little guidance regarding how to do so, what elements of a client's individual history to pay attention to, or what elements of the client's relationship to address.
