The results of an uncontrolled study of Gottman Method Couples Therapy in changing relationship satisfaction with 106 gay and lesbian couples is reported in this paper. Measurement of relationship satisfaction was conducted at five separate time points. The data show significant improvements in relationship satisfaction following eleven sessions of therapy for both gay male and lesbian couples. Effect sizes suggest that this therapy was highly effective, compared to the usual 0.5 standard deviation effect size in couples therapy. Initial co-morbidities did not affect the size of the changes; in fact, some changes were significantly larger for three initial co-morbidities.
