Introducing the Expectations and Preference Scales for Couple Therapy (EPSCT): Development, Psychometric Evaluation,...

While it is known that client factors account for the largest proportion of outcome variance across treatment modalities, little is known about how clients' characteristics affect the process and effectiveness of couple therapy. To further knowledge in this area, we created a brief, practice-friendly measure, the Expectation and Preference Scales for Couple Therapy (EPSCT). Three self-report scales assess clients' Outcome expectations (e.g., I expect our relationship to improve as a result of couple therapy) and role expectations for Self (e.g., I expect to listen to my partner's concerns) and Partner (e.g., I expect my partner to blame me). Three Cognitive-Behavioral, Emotionally Focused, and Family Systems preference scales use a forced-choice format to measure the comparative strength of respondents' preferences for interventions broadly reflective of each approach. A large item pool was developed from relevant literature and clinical experience and refined based on face and content analyses with two panels of experienced couple therapists and researchers. Across four studies with 1,175 participants, the scales' internal consistency reliabilities were similar and their construct validity was supported with confirmatory factor analyses and significant correlations with several established measures, including expectation measures developed for individual psychotherapy and measures of attitudes toward professional help seeking and valuing personal growth. Across all studies, participants had stronger role expectations for themselves than their partners, although gender effects differed by sample. We discuss how to use the 15-item EPSCT in clinical practice and in future research as a predictor of couple therapy processes and outcomes.
