Impact of marital and psychological distress on therapeutic alliance in couples undergoing couple therapy.

In this study, we describe the psychometric properties of the Couple Therapy Alliance Scale--revised (CTAS-r) and investigates the impact of marital and psychiatric distress on alliance. Seventy-nine couples in therapy completed a French version of the Dyadic Adjustment Scale and of the Psychiatric Symptoms Index at session one, and a French version of the CTAS-r at session three. Results indicate that the French version of the CTAS-r has adequate psychometric properties, although the subscales of the instrument are highly intercorrelated. Furthermore, marital adjustment predicts alliance scores, whereas psychiatric symptoms do not. Finally, male marital adjustment and female psychiatric symptoms are lower in couples where spouses have divergent perceptions of the alliance. Future research directions are discussed.
