Study summary

The goal of this clinical trial is to learn if a telemedicine-based virtual reality clinic (Doxy.me VR) works to treat dog, spider, and snake phobias in adults. The main questions it aims to answer are:

Does Doxy.me VR decrease the severity of phobias better than traditional telemedicine-based treatment? Does this work because it feels more realistic than telemedicine alone?

Study arms

  • Experimental
    Telemedicine-based Virtual Reality Exposure Therapy

    This group will receive exposure therapy in a telemedicine-based Virtual Reality Clinic using virtual reality snakes, dogs, or spiders. The VR stimuli range from small to medium to large and have four activity levels: idle, calm, energetic, and aggressive.

    Behavioral: Telemedicine-Based Virtual Reality Exposure Therapy

  • Active comparator
    Standard Telemedicine-Based Exposure Therapy

    This group will receive exposure therapy via Doxy.me telemedicine platform using photos and videos of snakes, dogs, or spiders. The photo/video stimuli range from small to medium to large and have four activity levels: idle, calm, energetic, and aggressive.

    Behavioral: Telemedicine-Based Exposure Therapy Using Photos and Videos

What researchers measure

Primary outcomes

  1. Phobia symptom severity

    The Severity Measure for Specific Phobia (SMSP) is a 10-item self-report questionnaire that assesses the severity of specific phobia symptoms relative to an individual's feared stimulus. Total scores range from 0 to 4 with higher scores indicating higher phobia severity.

    Time frame: Baseline, 4 Weeks Post-Baseline (Mid-Treatment), 7 Weeks Post-Baseline (Post-Treatment), and 28 weeks Post-Baseline (3-Months Post-Treatment)

  2. Dog Phobia Severity

    The Dog Phobia Questionnaire (DPQ) is a 27-item, self-report questionnaire assessing the severity of dog phobia symptoms. Scores range from 27 to 189 with higher scores indicating higher phobia severity.

    Time frame: Baseline, 4 Weeks Post-Baseline (Mid-Treatment), 7 Weeks Post-Baseline (Post-Treatment), and 28 weeks Post-Baseline (3-Months Post-Treatment)

  3. Snake Phobia Severity

    The Snake Anxiety Questionnaire (SNAQ) is a 30-item self-report questionnaire assessing the severity of snake phobia symptoms. Scores range from 0 to 30 with higher scores indicating higher phobia severity.

    Time frame: Baseline, 4 Weeks Post-Baseline (Mid-Treatment), 7 Weeks Post-Baseline (Post-Treatment), and 28 weeks Post-Baseline (3-Months Post-Treatment)

  4. Spider Phobia Severity

    The Fear of Spiders Questionnaire (FSQ) is an 18-item self-report questionnaire assessing the severity of spider phobia symptoms. Scores range from 18 to 126 with higher scores indicating higher phobia severity.

    Time frame: Baseline, 4 Weeks Post-Baseline (Mid-Treatment), 7 Weeks Post-Baseline (Post-Treatment), and 28 weeks Post-Baseline (3-Months Post-Treatment)

Secondary outcomes

  1. Specific Phobia Diagnosis

    The Diagnostic Assessment Research Tool (DART) is a modular semi structured interview corresponding with the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5). Study therapists administer the DART Specific Phobia Module, which provides designations of Absent, Subthreshold, and Present.

    Time frame: Baseline, 4 Weeks Post-Baseline (Mid-Treatment), 7 Weeks Post-Baseline (Post-Treatment), and 28 weeks Post-Baseline (3-Months Post-Treatment)

  2. General Anxiety

    The Generalized Anxiety Disorder-7 (GAD-7) is a 7-item self-report measure of anxiety symptom severity. Scores range from 0 to 15 with higher scores indicating higher anxiety severity.

    Time frame: Baseline, 7 Weeks Post-Baseline (Post-Treatment), and 28 weeks Post-Baseline (3-Months Post-Treatment)

  3. Depression Severity

    The Patient Health Questionnaire-8 (PHQ-8) is an 8-item self-report measure of depression symptom severity. Scores range from 0 to 27 with higher scores indicating higher depression severity.

    Time frame: Baseline, 7 Weeks Post-Baseline (Post-Treatment), and 28 weeks Post-Baseline (3-Months Post-Treatment)

  4. Quality of Life Level

    The Quality of Life Scale (QOLS) is a 16-item self-report measure of quality of life. Scores range from 16 to 112 with higher scores indicating better quality of life.

    Time frame: Baseline, 7 Weeks Post-Baseline (Post-Treatment), and 28 weeks Post-Baseline (3-Months Post-Treatment)

  5. Level of Telepresence

    The iGroup Presence Questionnaire (iPQ) is a 14-item self-report questionnaire of telepresence. Scores on each subscale range from 0-6 with higher scores indicating more presence.

    Time frame: Week 1, Week 2, Week 3, Week 4, Week 5, Week 6, Week 7; Averaged across weeks

  6. Cybersickness Severity

    The Cybersickness in Virtual Reality Questionnaire (CSQ-VR) is an 6-item measure of nausea, vestibular, and oculomotor cybersickness experienced in virtual reality. Scores range from 6 to 27 with higher scores indicating higher levels of cybersickness.

    Time frame: Week 1, Week 2, Week 3, Week 4, Week 5, Week 6, Week 7; Averaged across weeks

  7. Level of Working (Therapeutic) Alliance

    The Working Alliance Inventory (WAI-SR) is a 12-item client-rated measure of therapeutic alliance. Total scores range from 1 to 5 with higher scores indicating a better therapeutic alliance.

    Time frame: 4 Weeks Post-Baseline (Mid-Treatment), 7 Weeks Post-Baseline (Post-Treatment)

  8. Satisfaction with Therapy

    The Satisfaction with Therapy and Therapist Scale-Revised (STTS-R) is a 13-item self-report questionnaire that assesses client satisfaction with treatment. Scores range from 0 to 60 with higher scores indicating higher satisfaction.
