Note: ^aParticipants were counted as “did not receive allocated intervention” if the intervention video was not started or was terminated in less than 18 mins (8 mins for booster intervention). ^bDue to a technical error, wait-list control participants were unable to complete the T2 assessment in some cases. ^cOne participant per condition did not complete the main outcome questionnaire and was thus excluded from the ITT analysis. ^dDue to a technical error during T2 of the WLC, sample size for the PP analysis differs between individual and parental stress analyses.
