Abstract

Highlights: Provoked vestibulodynia is a vulvar pain condition causing sexual dysfunction. Predictors/moderators of outcomes after couple vs. medical intervention are unknown. Demographics, clinical and interpersonal variables predicted pain outcomes. Anxiety and sexual motivations moderated treatment efficacy for women's sexual function. Findings will assist clinicians in determining who benefits most for which treatment. Abstract: Provoked vestibulodynia is a vulvar pain condition causing sexual dysfunction, affecting 8% to 10% of women. Our recently published randomized clinical trial ( N = 108 couples) found that cognitive behavioral couple therapy (CBCT) and topical lidocaine reduced women's pain and associated sexual symptoms, with CBCT showing more benefits. Little is known about pretreatment predictors of treatment outcomes in couples sex therapy. In the current study, we examined women and their partners' pretreatment demographic (age, relationship length), clinical (pain duration, anxiety) and interpersonal (partner responses to pain, sexual goals) predictors/moderators of women's pain intensity, pain unpleasantness, and sexual function at posttreatment and 6-month follow-up. Longer relationship duration, lower anxiety in women, partner higher solicitousness and partner higher approach sexual goals predicted better pain outcomes for women with PVD irrespective of treatment condition. CBCT was more effective than lidocaine for improving women's sexual function at posttreatment when, at pretreatment, women had partners with higher anxiety and women reported lower approach sexual goals, whereas lidocaine was more effective for improving women's sexual function at follow-up when partners had higher approach sexual goals. Findings can assist clinicians in determining what treatment will be most beneficial for whom.
