About this trial
This NIH-funded single-arm pilot tests the feasibility, acceptability, and preliminary effects of embedding brief guided mindfulness practice (via the Waking Up smartphone app) into the inter-session intervals of clinically administered accelerated intermittent theta-burst stimulation (aiTBS) for major depressive disorder (MDD). Participants receive aiTBS as standard clinical care at MUSC; the research intervention is daily guided mindfulness practice during the aiTBS course. Outcomes include feasibility/acceptability, changes in state mindfulness and hedonic tone (Day 0 to Day 5), perceived ease of meditation, trait mindfulness at 4 and 12 weeks, and durability of antidepressant response (PHQ-9) at 4 and 12 weeks.

Treatments tested in this trial
Guided Mindfulness Practice using a study created web app that links to the commercially available Waking Up app
Behavioral5-15 minutes of mindfulness exercises during aiTBS inter-session intervals (9 total per day) for five consecutive treatment days; optional additional practices allowed. App analytics (with permission) and self-reports quantify engagement.
Treatment groups
Trial outcomes
Primary outcomes
Feasibility of Guided Mindfulness Practice During aiTBS (Adherence Rate)
Proportion of participants who complete all mandatory guided practice on each of the five aiTBS treatment days. Calculated as: number completing all five days ÷ total enrolled. Higher values indicate better feasibility.
Tolerability of Guided Mindfulness Practice During aiTBS (Adverse Events)
Number and severity of meditation-related adverse events recorded via participant report and study staff observation. Higher values indicate worse tolerability.
Secondary outcomes
Change in State Mindfulness (Toronto Mindfulness Scale Total Score)
Change in Toronto Mindfulness Scale (TMS) total score from baseline to Day 5. Higher scores indicate greater state mindfulness.
Change in Hedonic Tone (Snaith-Hamilton Pleasure Scale Total Score)
Change in Snaith-Hamilton Pleasure Scale (SHAPS) total score from baseline to Day 5. Lower scores indicate improved hedonic tone.
Change in Perceived Ease of Meditation (0-10 Rating)
Change in meditation ease rating on a 0-10 numeric scale (0 = not at all easy; 10 = extremely easy). Higher scores indicate greater perceived ease.
Change in Trait Mindfulness (CAMS-R Total Score)
Change in Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) total score from baseline to Week 12. Higher scores indicate greater trait mindfulness.
