Implementing Virtual Reality Exposure Therapy for Vaginismus: From Efficacy to Clinical Integration (VIVID 3) (VIVID 3)

30 juli 2026 bijgewerkt door: Lori Brotto, University of British Columbia
Vaginismus, a condition characterized by involuntary tightening of the pelvic floor muscles due to strong fear of vaginal insertion, impact ≥6% of the female population and can make vaginal intercourse and medical exams difficult. This project explores virtual reality exposure (VRE) as a new treatment approach. Building on our two previous studies showing that VRE is feasible and effective in helping patients to gradually face feared sexual encounters in a virtual environment, we aim to implement our VRE protocol at the BC Centre for Vulvar Health (BCCVH). We will assess barriers/facilitators to implementation, clinician uptake, and patients' outcomes and engagement.

Gedetailleerde beschrijving

PURPOSE: Vaginismus is a gynecologic condition characterized by involuntary tightening of the pelvic floor muscles. It is defined by intense fear of vaginal insertion, leading to persistent difficulties with vaginal intercourse and gynaecological exams The anticipation of pain provokes hypervigilance, negative cognitions, and avoidance behaviour, leading vaginismus to be conceptualized as a phobia. Equipped with data from Studies 1 and 2 from our 3-stage program for VRE to treat vaginismus, we have demonstrated that our VRE paradigm is feasible to deliver, usable, satisfactory to participants, and highly efficacious. We are now ideally positioned to evaluate the implementation of our VRE paradigm at VCH's BCCVH, which offers multidisciplinary treatment for individuals with chronic and distressing vulvo-vaginal pain and fear of vaginal insertion. Our goal is to use implementation science to study the phased implementation of our VRE protocol within the BCCVH, ultimately leading to better treatment options for women with vaginismus.

JUSTIFICATION: Lack of effective treatments: While vaginismus is common, believed to impact 6% of the female population, it remains underdiagnosed, effective treatment options are limited, and patients often feel dismissed by care providers. Available psychological treatments for vaginismus rely on gradual self-insertion of vaginal dilators at home combined with psychological therapy. However, many individuals experience severe fear and avoidance that make it difficult to engage with these exercises, reducing treatment success. VRE Theoretical approach: This project uses a theoretical approach recognizing that the psychological fear of pain drives hypervigilance to sexual stimuli, leading to physiological responses such as tightening of the pelvic floor muscles which in turn causes physical pain. Thus, addressing fear is a key piece of managing this condition and can be achieved through fear extinction approaches such as exposure therapy. Traditionally, this approach involves repeatedly exposing an individual to the fear-inducing stimulus until their fear decreases (habituates). When exposure is successful, a new association develops and inhibits the retrieval of the original fear memory. Our VRE paradigm is built upon this theory. VRE immerses people in 3D simulations of feared situations and is as effective as real-life exposure for specific phobias. VRE for vaginismus is gradual exposure to feared sexual encounters in a virtual environment and can diminish phobic responses to vaginal insertion. Given that people with vaginismus cope via intense avoidance and often do not perform recommended at-home exposure exercises, the "immersive" nature of VRE ideally target this avoidance.

PROOF OF CONCEPT: Findings from Study 1 & 2 of this 3-stage VRE research program showed that: 1) VR sexual stimuli elicit a greater fear in individuals with vaginismus relative to individuals without, 2) most participants would participate in a VRE intervention in clinic if it was available, and 3) participants strongly support the efficacy of the VRE approach. Together, these findings support the readiness to move forward with preparing for clinic implementation of this approach. The BCCVH is a provincial referral centre providing interdisciplinary, evidence-based care for vulvar and pelvic pain conditions, seeing 250 new patients each year. Its established clinical infrastructure, patient volume, and commitment to innovation make it an ideal setting to evaluate the implementation of VRE within existing clinic workflow.

OBJECTIVES: Our goal is to use implementation science to study the phased implementation of our VRE protocol within the BCCVH. The specific aims are to: (1) Conduct a barriers/facilitators assessment; (2) Evaluate clinician uptake, feasibility, and acceptability with pilot implementation of VRE; and (3) Assess patient reported outcomes of anxiety, sexual distress, pain, and home treatment engagement after VRE.

Beschrijving

Inclusion Criteria:

  • Diagnosis of vaginismus defined by a "marked fear or anxiety about vulvovaginal or pelvic pain in anticipation of, during, or because of vaginal penetration" (criterion from the DSM-5 definition of Genito-Pelvic Pain Penetration Disorder)
  • Aged >19 y, of any sexual orientation
  • Fluent in English (psychoeducational materials and questionnaires delivered in English)
  • Normal or corrected-to-normal vision (to view the VR scenes during exposure)
  • Able to travel to Vancouver

Exclusion Criteria:

  • Presence of: unprovoked vaginal pain
  • Vulvar skin condition (i.e., lichen sclerosus)
  • Epilepsy characterized by photosensitive seizures.

Note: provoked vulvar pain is not an exclusion criterion because at least 40% of people with vaginismus report pain with attempted penetration.

Experimenteel: Implementation of Virtual reality exposure
The investigators designed the VRE protocol based on our two studies: one proof-of-concept study, and a second study measuring VRE efficacy (both manuscripts under review). We found our VRE protocol to be highly feasible, usable, satisfying, and to lead to significant improvements in our outcomes focused on ease of vaginal insertion and associated vaginal pain. Participants will take part in a one-time 120-minute session, in addition to standard clinical care at the BCCVH, and complete study questionnaires before the VRE session and at follow-up time points to evaluate clinical outcomes. The VRE session will adhere to 3 key principles: (i) Exposure is prolonged; patients view a sexual scene multiple times; (ii) Treatment proceeds gradually, with the sexual activities depicted moving from non-penetrative (low fear) to penetrative (high fear); and (iii) Exposures are repeated, with participants re-watching the videos until their fear response has habituated.
Gedragsmatig: Implementation of Virtual Reality Exposure

To inform implementation, clinicians at BCCVH (n=6) will participate in individual semi-structured interviews prior to implementation to identify barriers and facilitators. Findings from these interviews will refine the implementation protocol. Following implementation, clinicians will complete questionnaires assessing implementation outcomes, including adoption, implementation, and maintenance.

Participants (n=167) will receive a single VRE session in addition to standard clinical care at the BCCVH. The VRE session is designed to support treatment of vaginismus and will be delivered according to the study protocol. Participants will complete study questionnaires at baseline and follow-up.
