Individuals with diverse and traditionally underrepresented sexual orientations – those who identify as lesbian, gay, or bisexual (LGB) – experience compounded stress due to their marginalized identity in a heteronormative society. Such stressors, which include but are not limited to discrimination and internalized heterosexism, increase risks for various affective disorders and negatively impact relationship functioning. Empirically supported relationship education programs, including the Couples Coping Enhancement Training (CCET), have been found efficacious in increasing psychological and relationship well-being; however, the original CCET and related education programs do not specifically target how couples can identify, communicate, and cope with sexual minority stressors. The purpose of this pilot study was to test the feasibility, acceptability, and preliminary evidence of effectiveness of the Couples Coping Enhancement Training – Sexual Minority Stress (CCET-SMS) relationship education program. Results from nine couples showed trends in decreased reports of sexual minority stress and general distress, and significant increases in reports of positive dyadic coping and relationship satisfaction. Additional results based on the program feasibility and acceptability along with limitations and suggestions for future directions are presented.
