Hypotheses
depression, sleep disturbance, anxiety
SECONDARY
For our primary hypothesis, we posited that CB for ~ 10 min/day over a 4-week period would lead to a greater reduction in self-reported (subjective) stress than practise of a breathwork placebo at post-intervention. We proposed the same at follow-up as a secondary hypothesis. Further secondary hypotheses included that CB would lead to greater improvement in subjective anxiety, depression, wellbeing and sleep disturbance than placebo at the same timepoints. As exploratory hypotheses, we postulated that greater self-reported adherence (in the intervention arm) and credibility/expectancy would be associated with greater improvements on the outcome measures at post-intervention.
