Guided internet‐based acceptance and commitment therapy for provoked vestibulodynia: A randomized controlled trial

Abstract Background Provoked vestibulodynia (PVD) causes suffering in many women's lives due to its impact on relationships, sexual functioning and functioning in other key domains. Objective Here, we report a randomized controlled trial conducted to examine whether Acceptance and Commitment Therapy (ACT) with a focus on values‐based exposure, delivered online, benefits women with PVD. Methods Participants ( n = 88) were randomized to either guided online ACT for 10 weeks or a wait‐list control group. Outcomes were assessed at baseline, post treatment and 1 year later. Analyses were based on intention to treat using linear mixed models. Results There were significant group differences on the primary outcomes, Female Sexual Index and Female Sexual Distress Scale, in favour of online ACT with moderate effect sizes. Differences were also found on several secondary outcomes and therapeutic process measures, all in favour of ACT. No differences were found at post‐treatment for depression or anxiety. At the 1‐year follow‐up, results were maintained and a difference between baseline and follow‐up was also found for depression. Conclusion/Significance In summary, a relatively brief, guided, online version of ACT appears to produce benefits for women with PVD and related impacts on daily functioning. 50% to 60% of the women who participated in the treatment reliably improved in sexual functioning and distress.
