“…Evidence for the causal effects of homework ( d = 0.53; 95% confidence interval [CI] = 0.35–0.72, p < 0.0001 in Kazantzis, Whittington & Dattilio, 2010) and for homework adherence as a predictor of symptom reduction (correlational effects, r = 0.26; 95% CI = 0.19–0.33 in Mausbach, Moore, Roesch, Cardenas & Patterson, 2010) is compelling, but perfect adherence is not expected because CBT supports change through a process of experimentation (i.e., collaborative empiricism, see discussion in Dozois, 2010). Prior surveys have confirmed that rates of homework adherence are often less than 100% in clinical practice (Helbig & Fehm, 2004; Kazantzis, Lampropoulos & Deane, 2005), and guidance has been provided for maximizing homework adherence in couples and family therapy work (Bevilacqua & Dattilio, 2001; Dattilio, 2002, 2005; Dattilio & Dickson, 2007; Dattilio, L'Abate & Deane, 2005; Epstein & Baucom, 2007; Newcomb & Lebow, 2007; Robbins, Szapocznik & Perez, 2007; Schumm & Renno, 2022). However, little research has surveyed couples and family therapists' experiences of CBT, and no prior study has examined the potential for positive or negative impact of homework non‐completion (IHN) on the working alliance (see reviews in Mutschler, Malivoire, Schumm & Monson, 2022; Sibley, Link, Torres Antunez & Greenwood, 2022).…”
