Contemporary MFT Models' Alignment with Relational Common Factors

Common factors theorists believe that therapy is effective, not only because of model specific elements, but also, because of common factors that cut across various treatment models. Common factors include extra-therapeutic factors such as treatment setting, therapeutic alliance, therapist variables and client variables. Common factors researchers have proposed a set of relational common factors that are unique to the practice of marriage and family therapy, including the ability to conceptualize difficulties relationally and the ability to disrupt dysfunctional relationship patterns. In this paper, I analyze and compare relational common factors in three contemporary models: narrative therapy, solution-focused therapy and cognitive-behavioral therapy. Finally, I discuss significant implications for theorizing, training and supervision.
