Lead Sponsor
University of Sussex
Brief 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.

Placebo HVBRPlacebo HVBRGuided audio of placebo HVBR pre-recorded by a trained breathwork facilitator for \~20min/day over 21 days (three weeks). Delivered remotely through audio link, comprising music and four rounds of paced breathing at 15b/min (equal inhale:exhale) with four separate brief retentions, progressively increasing in length (from \~10secs to \~25secs).

Primary Outcome Measures
NameTimeMethod
Subjective stressPre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention). Primary timepoint is post-intervention

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

Secondary Outcome Measures
NameTimeMethod
Subjective anxietyPre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention)

DASS-21 - anxiety subscale (score range: 0-21; higher scores denote worse outcome)

Subjective positive affectPre-intervention (immediately before the intervention), post first breathwork session (immediately after starting breathwork), and post-intervention (immediately after the intervention)

Positive and Negative Affect Schedule (PANAS) positive affect subscale (score range: 10-50; higher scores denote better outcome)

Subjective sleep-related impairmentPre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention)

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

Subjective depressive symptomsPre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention)

DASS-21 - depression subscale (score range: 0-21; higher scores denote worse outcome)

Subjective mental wellbeingPre-post intervention and follow-up (immediately before the intervention, immediately after the intervention, and three weeks after the intervention)

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

Negative side effects due to protocolPost-intervention (immediately after the intervention)

Whether participants experienced unpleasant/unwanted short-term effects and/or lasting bad effects from the breathwork

Subjective negative affectPre-intervention (immediately before the intervention), post first breathwork session (immediately after starting breathwork), and post-intervention (immediately after the intervention)

PANAS negative affect subscale (score range: 10-50; higher scores denote worse outcome)

Subjective credibility and expectancy of protocolImmediately after starting breathwork intervention

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

Self-reported adherence to protocolPost-intervention (immediately after the intervention)

Number of sessions participants self-report practicing out of 21 days assigned
