November 15, 2018 updated by: University of Florida
The purpose of this study is the evaluate the extent to which an intervention aimed at reducing pain-related fear affects sexual function and pain sensitivity compared to usual care.

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The overarching goal of this work is to identify the mechanisms underpinning sexual pain in women. Women with sexual pain exhibit higher vaginal pain sensitivity and lower levels of sexual desire and arousal compared to pain-free women. As a result of pain, sexual intercourse is avoided. Previous work in this area has examined a wide variety of interventions for sexual pain but has not examined how vaginal pain sensitivity and resulting sexual dysfunction may be mediated by pain-related fear. The study team proposes that a standardized exposure intervention that directly targets pain-related fear will in turn reduce vaginal pain sensitivity and translate to clinically meaningful changes in sexual function. The study team will assign women with sexual pain to receive a home-based, patient-controlled exposure intervention or standardized home-based home program. The specific aims of this proposal are: 1) To evaluate the extent to which pain-related fear mediates vaginal pain sensitivity in women with sexual pain; 2) To evaluate the extent to which graded exposure translates to changes in sexual function and partner dynamics. The completion of this work will provide us with a better understanding of the mechanisms underpinning sexual pain and specifically, how pain-related fear influences vaginal pain sensitivity and sexual function.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Inclusion Criteria:

  • Females with sexual pain >= 6 months
  • Appropriate to use vaginal dilators

  • The ability and willingness to follow all requirements of the study including following all directions and completion of daily pain reports
  • Signed informed consent
  • Are sexually active (have had intercourse at least twice in the last 30 days)
  • Pain-related fear of intercourse greater than 50 on the numerical fear rating scale

Exclusion Criteria:

  • Physical, psychological and medical issues, encountered during routine care that are felt insufficient for trial participation (physician discretion), such as poor mental status or neurological deficit limiting participation physically or cognitively (Mini-mental state exam less than 20).
  • Women with sexual pain who are not sexually active (have not had intercourse at least twice in the last 30 days)
  • Participants who use narcotic pain medication
  • Participants diagnosed with a major depressive disorder
  • Participants who exhibit signs and symptoms of infection, malignancy, or other conditions identified by a member of the study team that may be contraindications to the use of dilators

  • Pain-related fear of intercourse less than 50 on the numerical fear rating scale
  • Women who are pregnant
  • Participants who report a history of sexual abuse or trauma.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Fear-based Dilator Progression group
Participants in this group will complete a home dilator program using levels of pain-related fear to progress through the program.
Device: Dilator
Both groups will have a home program consisting of dilators which are progressive in size. The standard care group will use manufacturer instructions to progress in size of dilators, while the experimental group will use self-reported levels of fear to progress in size of dilators.
Behavioral: Fear-Based Questionnaires
Series of questionnaires used to facilitate emotional awareness associated with vaginal and decreased sexual arousal.
Active Comparator: Standard Dilator Progression Group
Participants in this group will complete a standard home program based on dilator manufacturer instructions for use.
Device: Dilator
Both groups will have a home program consisting of dilators which are progressive in size. The standard care group will use manufacturer instructions to progress in size of dilators, while the experimental group will use self-reported levels of fear to progress in size of dilators.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Vaginal Pain sensitivity
Time Frame: 40 days
A change in pressure pain sensitivity at the vagina using a Wagner Digital Algometer.
40 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Sexual function
Time Frame: 40 days
Assessed using the Female Sexual Function Index (FSFI), a 19- item questionnaire that measures desire, arousal, lubrication, orgasm, satisfaction, and pain in women with pelvic pain. This measure has high internal consistency (Cronbach's alpha 0.91-0.97) and good test-retest reliability (r=0.79-0.90).
40 days
Sexual Distress
Time Frame: 40 days
Assessed using the Female Sexual Distress Scale-Revised (FSDS-R), a 13-item questionnaire that evaluates negative emotions about sexuality and sexual relations. The internal consistency of this measure is high (Cronbach's alpha 0.86- 0.94) with good test retest reliability (ICC= 0.74).
40 days
Partner dynamics
Time Frame: 40 days
Assessed using the Revised Dyadic Adjustment Scale(RDAS), a 14-item questionnaire that assesses three overarching dimensions of relationships, including Consensus, Satisfaction, and Cohesion. This measure has high internal consistency (Cronbach's alpha= 0.90).
40 days
