Interventions

  • Improving Engagement with Vaginal Dilator Therapy after Pelvic Radiation — BEHAVIORAL
    The intervention includes coping strategies from cognitive behavioral therapy (e.g., progressive muscle relaxation) and acceptance and commitment therapy (e.g., mindfulness), as well as psychoeducation (e.g., how to use dilators), to enhance engagement with vaginal dilator therapy.

Study Details

This study is testing a new program to help women who have had pelvic radiation therapy to use vaginal dilators more regularly. Vaginal dilators are important tools that can help prevent or treat vaginal narrowing (called vaginal stenosis), which can happen after radiation and make medical exams or sexual activity painful or difficult. Even though dilators are recommended, many women don't use them as often as needed. In this study, 88 participants will be randomly assigned to one of two groups: * One group will receive the new behavioral program, which includes support and strategies to help with regular dilator use. * The other group will receive written educational materials (enhanced usual care). The study will look at how often and how long participants use their dilators, and whether the program helps reduce symptoms like pain or emotional distress. Participants will complete surveys at the beginning of the study and again at 3, 6, and 9 months, plus short monthly check-ins. The goal is to see if the program is helpful and easy to use, and to prepare for a larger study in the future.

Arms

  • Experimental: Improving Engagement with Vaginal Dilator Therapy after Pelvic Radiation
    A 6-session (45 minutes each) behavioral intervention will be delivered individually and remotely via videoconferencing. The intervention will be designed to improve engagement with vaginal dilator therapy among female cancer survivors who underwent pelvic radiation therapy. The intervention includes coping strategies from cognitive behavioral therapy (e.g., progressive muscle relaxation) and acceptance and commitment therapy (e.g., mindfulness), as well as psychoeducation (e.g., how to use dilators), to enhance engagement with vaginal dilator therapy.
  • No Intervention: Enhanced Usual Care
    Written materials will highlight the purpose of dilator therapy and how to use dilators (including frequency and duration).
