Clinical Trial Summary

The investigators are conducting a randomised-controlled trial comparing high ventilation breathwork with retention (HVBR) to a breathwork placebo (paced breathing at 15breaths/min with brief retentions). The metric of 15b/min aligns with guidance from the British Journal of Nursing, Royal College of Physicians and Johns Hopkins Medicine which state that the average, healthy rate should range from: 12-20, 12-18 and 12-16b/min, respectively. The main questions the study attempts to address are: Does HVBR lead to improved state and trait mental health and wellbeing in a general population adult sample? The study will be conducted entirely online through the research platform Prolific, so participant data will be anonymous. The investigators will collect self-reports of mental health and wellbeing before and after the three-week breathwork period, in addition to a follow-up three weeks later. Pre-post intervention and follow-up questionnaires will be completed online via the survey platform Qualtrics which will be linked to Prolific. Data on self-reported adherence to, and credibility/expectancy of, the breathwork will also be collected, along with participants' experiences to gauge the safety and tolerability of the breathwork protocol.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Overall experience	Participants' perspectives and overall experience of the protocol/study-period	Post-intervention and follow-up (immediately after the intervention, and three weeks after the intervention)
Other	Hypothesis guessing	Whether participants can correctly guess which condition they were allocated to	Follow-up (three weeks after the intervention)
Primary	Subjective stress	Depression Anxiety Stress Scale-21 (DASS-21) - stress subscale (score range: 0-21; higher scores denote worse outcome). Score on DASS-21 then multiplied by two to convert it to the longer form DASS-42 final score	Pre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention). Primary timepoint is post-intervention
Secondary	Subjective anxiety	DASS-21 - anxiety subscale (score range: 0-21; higher scores denote worse outcome)	Pre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention)
Secondary	Subjective depressive symptoms	DASS-21 - depression subscale (score range: 0-21; higher scores denote worse outcome)	Pre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention)
Secondary	Subjective mental wellbeing	Short Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS) (score range: 7 to 35; higher scores denote better outcome). Total raw scores are then transformed into metric scores using the SWEMWBS conversion table on: www.warwick.ac.uk	Pre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention)
Secondary	Subjective sleep-related impairment	PROMIS Item Bank v. 1.0 - Sleep-Related Impairment - Short Form 4a (score range: 5-20; higher scores denote worse outcome). Data scored using a T-score transformation according to PROMIS Sleep scoring manual on: www.healthmeasures.net	Pre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention)
Secondary	Subjective positive affect	Positive and Negative Affect Schedule (PANAS) positive affect subscale (score range: 10-50; higher scores denote better outcome)	Pre-intervention (immediately before the intervention), post first breathwork session (immediately after starting breathwork), and post-intervention (immediately after the intervention)
Secondary	Subjective negative affect	PANAS negative affect subscale (score range: 10-50; higher scores denote worse outcome)	Pre-intervention (immediately before the intervention), post first breathwork session (immediately after starting breathwork), and post-intervention (immediately after the intervention)
Secondary	Subjective credibility and expectancy of protocol	Credibility/Expectancy Questionnaire (CEQ-6). Two Sets (Credibility of course/therapy [breathwork] and expectancy of course/therapy [breathwork]). Four items scored 1-9 and two items scored 0-100%. Scores for expectancy set then standardised via converting them to z-scores. Higher scores denote greater credibility and/or expectancy of specific breathwork technique	Immediately after starting breathwork intervention
Secondary	Negative side effects due to protocol	Whether participants experienced unpleasant/unwanted short-term effects and/or lasting bad effects from the breathwork	Post-intervention (immediately after the intervention)
Secondary	Self-reported adherence to protocol	Number of sessions participants self-report practicing out of 21 days assigned	Post-intervention (immediately after the intervention)
