Multidisciplinary approach to the treatment of sexual dysfunction in couples using a biopsychosocial model

Given the complexity of the psychological and biological pathologies associated with sexual dysfunction, which affects at least a third of adult women and men worldwide, a multidisciplinary approach has been advocated.

To assess sexual functioning, relationship satisfaction, and mood stability pre- and post- treatment at the Loyola University Sexual Wellness Program.

Couples attending the 6-week multidisciplinary Sexual Wellness Program provided consent and completed pre- and post- intervention assessments. Linear mixed effects models were used to estimate the mean change from baseline to first follow-up. A covariance matrix was used to account for dependency.

All patients completed self-reported surveys: Dyadic Adjustment Scale, PROMIS Sexual Function and Satisfaction Measures Brief Profile (Patient-Reported Outcomes Measurement Information), and International Index of Erectile Function.

There were 85 respondents: 42 men and 43 women. The mean age was 49.82 years (range, 25-77). The largest improvement was on the total Dyadic Adjustment Scale score, which increased by approximately 5.18 points (95% CI, 2.55-7.81). PROMIS scores for global satisfaction with sex life, erectile function, and interest in sexual activity significantly increased from baseline, while the vaginal discomfort score significantly declined. Overall the score for global satisfaction with sex life increased from baseline by approximately 5.57 points (95% CI, 3.03-8.10). On average, men reported a 4.33-point increase (95% CI, 0.04-8.62) in their International Index of Erectile Function score from baseline.

A multidisciplinary treatment approach focused on the couple positively affects a couple's relationship, including global satisfaction with sex life, relationship satisfaction, interest in sexual activity, and erectile function.

This study is one of the few to document the effects of a multidisciplinary treatment approach for both members of a heterosexual couple-male and female. Limitations include the narrow demographics and lack of a control group in our population. Furthermore, this was completed at 1 academic center.

These findings emphasize that multidisciplinary sexual therapy programs aimed at the couple can help address multiple aspects of sexual well-being.
