CBT Group Treatment for Women With Dyspareunia

Study Overview
=================
Brief Summary
-----------------
The current study will employ a group CBT treatment program of 10 group sessions and 3 individual couple sessions targeting the thoughts, emotions, behaviors and couple interactions associated with the experience of dyspareunia. Women with superficial dyspareunia and their partners will be randomized to the CBT group program-plus or a waiting list control period at one treatment location in Sweden and two treatment locations in the Netherlands. The waiting-list control period will be comparable to the treatment duration of six months. It is hypothesized that the group program-plus is more effective in improving pain during intercourse in women with superficial dyspareunia compared to women on a waiting-list control period.

Detailed Description
-----------------
Rationale: Superficial dyspareunia, a frequent form of chronic genital pain, is associated with decreased sexual function for afflicted women, as well as impoverished sexual satisfaction for women and their partners. While recent research has showed that cognitive-behavioral therapy (CBT) interventions have effects in regards to reducing pain, enhancing sexual function and improving relational aspects, randomized controlled trials are still sparse. Despite recommendations in the literature to include the partner in the CBT treatment targeted at improving pain and sexuality outcomes, there are no published randomized CBT controlled trials incorporating the partner in the treatment. Primary objective: To evaluate whether the group program-plus improves pain during intercourse in women with superficial dyspareunia compared to women in a waiting-list control condition. Secondary Objective(s): are to evaluate a) women (and partners) sexuality (sexual function, distress & satisfaction), b) women's psychological adjustment (negative and positive penetration beliefs, pain/penetration coping behavior); c) relationship factors (partner responses and relationship satisfaction), and whether an improvement in pain during intercourse is moderated by pre-treatment patient characteristics, such as age, sexual functioning, relationship satisfaction, abuse history, and mediated by a) reduction of negative penetration beliefs, avoidance behavior and/or improvement in positive penetration beliefs and sexual function (i.e. sexual arousal). Study design: Eligible women and their partners in one of the participating centers (n=3, in two countries) will be randomized to either the CBT group program-plus or waiting-list control group (WLC), using a block randomization design stratified for each center. The waiting-list period of 6 months is comparable to the period from the start of the active treatment until the post-treatment measurement. After the WLC, the patients from the WLC will receive the active treatment. Data of these participants will be included in the repeated measures analyses to test the temporal stability of treatment gains. Within-subjects repeated measures comparisons will be conducted for data of participants and their partners at pre-treatment, post-treatment, follow-up at 3 months and 6 months following treatment termination. In addition, participants complete monthly questionnaires at home during the first 6 months. Participants in the active treatment group will also complete weekly measures. These extra measurement are necessary for the mediation analyses. The total study duration (including follow-up) for the participants and their partners is 12-18 months. Intervention: The CBT group program-plus consists of 3 1-hr CBT couple sessions and 10 2-hr CBT group sessions over a period of 6 months. The manualized treatment comprise, pain- and sexual education, relaxation and gradual exposure exercises as well as sensate focus and sexual communication exercises for the couple. 6-8 women participate in each group. Two psychologists will conduct the couple and group sessions.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean level of pain during penile/vaginal intercourse (PI) | Pain intensity is measured on a scale between 0-10 | 6 months; 9 months; 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Penetration behavior questionnaire (PBQ) | The PBQ has seven questions inquiring about the woman's experience during the last month with the following aspects of vaginal penetration: full vaginal penetration with the penis of the partner, self-insertion in the vagina of one finger by the woman, self-insertion in the vagina of two fingers by the woman, insertion in the vagina of one finger by the partner, insertion in the vagina of two fingers by the partner, and self-insertion in the vagina of another object (such as a tampon or a dildo) by the woman and by the partner. Answering categories are as follows: (a) not attempted; (b) attempted, but unsuccessful; (c) attempted and sometimes successful; and (d) attempted and always successful. The total of the scale is calculated and ranges between 4-28. | 6 months; 9 months; 12 months | 
| Genital pain rating questionnaire (GPQ) | Genital pain experienced by touch and penetration of the vagina will be assessed with the 7- item Genital Pain rating Questionnaire (GPQ). Response categories vary from 0 (not at all) to 10 (worst pain imaginable). The questionnaire consist of two sub-scales: the first sub-scale 'pain on touch and finger insertion'' consists of 6 items (pain by touch of the vulva by the patient herself, pain by touch of the vulva by the patient's partner, pain during insertion of one/two own finger(s) into the vagina, and pain during insertion of one/two finger(s) of the patient's partner) into the vagina. The range of the sub-scale is 0-60. The second sub-scale is 1 item related to pain during intercourse (0-10). | 6 months; 9 months; 12 months | 
| Female Sexual Function Index (FSFI) | Female Sexual functioning will be assessed with the 19-item Female Sexual Function Index (FSFI). It covers six domains of sexual functioning: sexual desire, sexual arousal, lubrication, orgasm, sexual satisfaction, and sexual pain. The answers are given on a Likert scale ranging from 0 or 1 to 5, depending on item. For the current study, the total FSFI score will be used, excluding the three items on sexual pain, which gives an indication of the sexual functioning during the past four weeks. The total score ranges between 2-30 with higher scores indicating higher sexual function. | 6 months; 9 months; 12 months | 
| Female Sexual Distress scale (FSDS) | Sexual related personal distress will be assessed with the 12-item Female Sexual Distress scale (FSDS). Questions are answered on a 0-4 Likert scale and the total score ranges from 0-48 with higher scores indicating higher sexual distress. | 6 months; 9 months; 12 months | 
| Global Measure of Sexual Satisfaction Scale (GMSEX) | Sexual satisfaction will be assessed with the 5-item Global Measure of Sexual Satisfaction Scale (GMSEX). GMSEX consist of five 7-point dimensions of sexual satisfaction ranging from Good to Bad, Pleasant to Unpleasant, Positive to Negative, Satisfying to Unsatisfying, and Valuable to Worthless. Total scores range from 5-35, with higher scores indicating greater sexual satisfaction. | 6 months; 9 months; 12 months | 
| Vaginal Penetration Cognition Questionnaire (VPCQ) | Positive and negative cognitions and beliefs regarding vaginal penetration will be assessed with the 22-item Vaginal Penetration Cognition Questionnaire (VPCQ). The VPCQ is a 22-item self-report measure using positive and negative statements about vaginal penetration and is answered on a 7-point Likert scale. Possible answers range from 0 = not at all applicable to 6 = very strongly applicable. The VPCQ consists of 5 subscales: Control Beliefs (4 items), Catastrophic and Pain Beliefs (5 items), Self-Image Beliefs (6 items), Positive Beliefs (5 items), and Genital Incompatibility Beliefs (2 items). | 6 months; 9 months; 12 months | 
| Painful Intercourse Self-Efficacy Scale (PISES) | Pain self-efficacy beliefs will be assessed using the 20-item Painful Intercourse Self-Efficacy Scale (PISES), it consists of three sub-scales: self-efficacy for controlling pain during intercourse, for sexual function, and for other symptoms. Answers are given on a 10-point scale ranging from (10) very uncertain to (100) very certain. | 6 months; 9 months; 12 months | 
| CHAMP Sexual Pain Coping Scale (CSPCS) | Avoidance and endurance coping behaviors during penetration will be assessed with the 12-item CHAMP Sexual Pain Coping Scale (CSPCS). This measure consists of three sub-scales: avoidance, endurance and alternative strategies. Respondents rate their agreement of each statement between 1 (Never true) and 7 (Always true). Total scores range from 4-28 on each sub-scale. | 6 months; 9 months; 12 months | 
| Maudsley Marital Questionnaire (MMQ) | Relationship satisfaction will be assessed with the 10 items of the marital dissatisfaction subscale of the Maudsley Marital Questionnaire MMQ. Possible range 0-80 with higher scores indicating greater dissatisfaction. | 6 months; 9 months; 12 months | 
| Approach and Avoidance Sexual Goals (AASG) | To assess sexual motives and goals the 15-item Approach and Avoidance Sexual Goals (AASG) measure will be used. Participants can rate the importance of 9 approach and 6 interpersonal goals in influencing their decision to engage in sex on a 7 point scale. | 6 months; 9 months; 12 months |
