Objectives: This study examined the structural family therapy model and the integrative behavioral couple therapy model from the perspective of common factors, exploring the integrative applicability of the two theoretical models, thus attempting to derive implications for family therapy. Methods: The study analyzed the common factors in family therapy of: “working with family system”, “working with the individual as a relationship change agent”, “evaluating couple system”, “training knowledge and skills for problem solving”, “facilitating experiential acceptance and communication within couples”, and “providing structure and safety for change”. Results: First, both models included common factors suggested in the study. Second, for the integration of the two models, a four-stage model of marriage and family counseling in structural family therapy was set as a counseling process, and the techniques of integrated behavioral couple therapy were integrated to reinforce the therapeutic effect at each step. Conclusions: The results of this study enhance the areas that should be addressed in family therapy research and clinical sites. The integrated approach of the two models will also enable more scientific and effective family therapy.
