NCT02754557

Brief Summary

The purpose of the study is to compare the efficacy of a physiologically-augmented breath-focused mindfulness-based intervention to reduce symptoms of dissociation that are associated with psychological trauma, as well as symptoms of posttraumatic stress disorder (PTSD). The study will evaluate whether physiological augmentation produces a greater change in dissociative symptoms, meditative engagement and attentional control, compared to non-augmented mindfulness. The augmentation comprises physiological feedback in the form of a vibration on the wrist. Vibrations are delivered by a device that will be placed on a participant's arm; the device vibrates in proportion to the person's breath.

Outcome Measures

Primary Outcomes (4)

  • Multiscale Dissociation Inventory (MDI) Score

    The MDI is a 30-item self-report test of dissociative symptomology and it measures six different types of dissociative response. The scales of the MDI are disengagement, depersonalization, derealization, emotional constriction/numbing, memory disturbance, identity dissociation, and total dissociation. Items are scored from 1 to 5 where 1 = never and 5 = very often. Total scores range from 30 to 150 where higher scores indicate greater symptoms of dissociation.

    Baseline, Week 4 (post-treatment), Week 8 (one month post-treatment)

  • Modified PTSD Symptom Scale (MPSS) Score

    The MPSS is an 18-item instrument assessing the presence and severity of PTSD symptoms related to specific traumatic events in individuals with a known trauma history. Respondents indicate how frequently they experience each item on a scale of 0 to 3 where 0 = not at all and 3 = almost always. PTSD symptomatology over the prior 2 weeks is assessed, yielding a continuous measure of PTSD symptom severity ranging from 0 to 54. A higher score indicates greater symptom severity.

    Baseline, Week 4 (post-treatment), Week 8 (one month post-treatment)

  • Kentucky Mindfulness Scale Score

    The Kentucky Mindfulness Scale is a 39-item scale that assesses skills related to what one does while practicing mindfulness. Items are rated on a 5 point Likert scale ranging from 1 (never or very rarely true) to 5 (almost always or always true). Items reflect either direct descriptions of the mindfulness skills, or they describe the absence of that skill and are reverse scored. Total scores range from 39 to 195 and higher scores reflect more mindfulness.

    Baseline, Week 4 (post-treatment), Week 8 (one month post-treatment)

  • Multidimensional Assessment of Interoceptive Awareness Score

    This is a clinical measure that assesses various aspects of interoception, including ability to attend to body sensations, regulate distress by attending to body sensations, and experiencing body sensations as safe and trustworthy. The instrument includes 32 items and which are scored from 0 to 5, where 0 = never and 5 = always. Total scores range from 0 to 160 and higher scores indicate greater awareness of body sensations.

    Baseline, Week 4 (post-treatment), Week 8 (one month post-treatment)

  • Change in Clinician Administered PTSD Scale (CAPS) Score

  • Change in Mini International Neuropsychiatric Interview (MINI) Score

Other: Breath-Focused MeditationDevice: Physiological Feedback

Interventions

Participants will attend two breath-focused meditation sessions per week for three weeks. During the breath focus task, participants are asked to alternatively focus their breathing (1.5 minutes of breathing and 15 seconds of rest). Participants will be asked to "attend to the changing patterns of physical sensations as the breath moves in and out of your body. Focus your awareness on any sensations you may experience (e.g., your abdominal wall rising). Follow the sensations as you breathe in and all the way through until your breath leaves your body".

Breath-Focused MeditationBreath-Focused Meditation + Physiological Feedback

Participants will receive breath feedback, via dynamic velocity estimates from a respiration belt, which allows an analog of breath to be felt as vibration on their wrist via a tactile transducer on a table. The transducer is tuned to produce low frequencies so there is more vibration and less of an audible component than a regular speaker would produce.
