Integrative Behavioral Couple Therapy vs. Traditional Behavioral Couple Therapy: A theoretical review of the differential effectiveness

The purpose of this review is to compare the differential effectiveness of two couple therapies, the Traditional Behavioral Couple Therapy (TBCT) and the Integrative Behavioral Couple Therapy (IBCT).
Although the latter can be seen as an evolution of the first, both are based on different theoretical concepts. Starting from the analysis of 12 studies comparing TBCT and IBCT, conclusions about effectiveness and future perspectives of both approaches are discussed. Our results show that TBCT and IBCT have distinct courses of change and differ fundamentally in what the therapist does in-session, impacting couple behavior both in and out of session. Currently, in line with the most important randomized trials in this field, a slight advantage for IBCT over TBCT in treating distressed couples at two points in time —when treatment is completed and in the first years post-therapy— can be confirmed, although at a five-year follow-up results equalize. Furthermore, some studies cannot confirm significant changes, but clinically relevant ones, which point toward a higher impact of IBCT. Lastly, the article includes limitations of the review as well and offers some orientations, which should be considered for future research.
