Overview
Brief Summary
The current pilot study aims to assess the feasibility and preliminary efficacy of a novel, 12-week targeted couple intervention (CBCT) for women with vulvodynia and their partners.
Detailed Description
Chronic pain problems involving the female reproductive system are major health concerns in women of all ages. As conditions which are poorly understood, they entail a great personal cost to patients and a significant financial cost to society. One such condition is vulvodynia, or chronic unexplained vulvar pain, which has a prevalence of 16%. Despite its negative impact on psychosexual and relationship satisfaction, there has been a paucity of research to provide empirically validated treatments for afflicted couples. The proposed research draws on findings from our work focusing on the influence of romantic relationships in the experience of vulvodynia as well as on our past studies evaluating the efficacy of group cognitive-behavioral therapy for this problem. The proposed pilot study aims to assess the feasibility and preliminary efficacy of a novel, 12-week targeted couple intervention (CBCT) for women with vulvodynia and their partners. The primary research question is: Is there a significant difference between pre- and post-treatment measures of pain during intercourse? We hypothesize that CBCT will yield pain reduction from pre- to post-treatment. The secondary research question focuses on pre- and post-treatment differences in 1) the multidimensional aspects of pain, 2) sexuality outcomes, 3) psychological adjustment, 4) relationship factors, and 5) patient self-reported improvement and treatment satisfaction. We hypothesize that the CBCT will result in significantly greater improvements on all outcome measures, and that the intervention will demonstrate adequate feasibility. Results of this study may improve the health and quality of life of patients afflicted with vulvodynia by helping us further develop this intervention for future clinical trial testing. For exploratory purposes, a 3-month follow-up assessment of treatment outcomes will also be conducted. This pilot trial addresses the urgent need for empirically validated treatments for vulvodynia, and will help refine an intervention for future clinical trial testing. Results may improve the health and quality of life of couples afflicted with this highly prevalent women's health care problem. Findings will generate information about the feasibility and preliminary efficacy of a frequently recommended intervention for PVD, counselling targeting the couple. The findings will help provide women with PVD and their partners with scientifically based treatment options and may allow them to reduce the pain experienced during intercourse, in addition to improving their sexual functioning, overall well-being, and romantic relationship.

Eligibility Criteria
Inclusion Criteria
- •pain during intercourse which is a) subjectively distressing, b) occurs on 80% of intercourse attempts, and c) has lasted for at least one year

- •having been sexually active as a couple in the last three months (intercourse, manual or oral stimulation)
- •in a committed relationship for at least six months
Exclusion Criteria
- •vulvar pain not clearly linked to intercourse or pressure applied to the vestibule
- •presence of one of the following: a) major medical and/or psychiatric illness, b) active infection, c) deep dyspareunia, d) vaginismus (as defined by DSM-IV), e) dermatologic lesion, f) pregnancy or planning a pregnancy

Outcomes
Primary Outcomes
Pain during intercourse (Visual analog scale)
Time Frame: change in the VAS scores from pre- to post-treatment, and from pre-treatment to 3-month post-treatment
Pain during intercourse will be assessed using a visual analog scale (VAS) ranging from 0 to 10, where 0 is no pain at all, and 10 is the worst pain ever. The main outcome will be the change in the VAS scores from pre- to post-treatment. This method for measuring pain has been shown to detect significant treatment effects in women with PVD and demonstrates a significant positive correlation with other pain intensity measures. Pain during intercourse is the main symptom of PVD and the one that most interferes with quality of life, hence the most relevant measure of functional outcome.
Secondary Outcomes
- Sexual function (Derogatis Interview for Sexual Functioning - Self-Report)(change in the DISF-SR scores from pre- to post-treatment, and from pre-treatment to 3-month post-treatment)
- Global Measure of Sexual Satisfaction scale(change in GMSEX scores from pre-to post-treatment, and from pre-treatment to 3-month post-treatment)
- Pain Catastrophizing Scale (PCS)(changes in PSC scores from pre-to post-treatment, and from pre-treatment to 3-month post-treatment)
- Beck Depression Inventory (BDI-II)(changes in BDI-II scores from pre- to post-treatment, and from pre-treatment to 3-month post-treatment)
- West Haven-Yale Multidimensional Pain Inventory - Significant Other Response Scale (MPI)(changes in MPI scores from pre- to post-treatment, and from pre-treatment to 3-month post-treatment)
- Couple Satisfaction Index (CSI)(changes in CSI scores from pre- to post-treatment, and from pre-treatment to 3-month post-treatment)
- Spielberger State-Trait Anxiety Inventory (STAI)(changes in STAI from pre-to post-treatment, and from pre-treatment to 3-month post-treatment)
- Self-reported improvement and satisfaction(Reported at the end of treatment)
- Painful Intercourse Self-Efficacy Scale (PISES)(Changes in PISES scores from pre-to post-treatment, and from pre-treatment to 3-month post-treatment)
