Design outcomes

Primary

MeasureTime frame
Sleep Onset Latency is measured using a parent-completed 10-day sleep diary at Baseline and month 3

Secondary

MeasureTime frame
1. Sleep Onset Latency is measured using a parent-completed 10-day sleep diary at Baseline and Month 6 2. Sleep Quality is measured using a parent-completed SASS-Y at Baseline, Month 3 and Month 6 3. Subjective report of child sleep is measured using SNAP-IV parent report at Baseline, Month 3 and Month 6 4. Irritability is measured using the Affective Reactivity Index (ARI) at Baseline, Month 3 and Month 6 5. Mental well-being is measured using the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) at Baseline, Month 3 and Month 6 6. Sleep problem score (parent report) is measured using the Omnibus Sleep Questionnaire (OSQ) at Baseline and Month 6 7. Quality of life of parent is measured using EQ-5D-5L at Baseline, Month 3 and Month 6 8. Quality of life of child is measured using the Child Health Utility 9D index (CHU-9D) proxy for children aged 7 to 12 at Baseline, Month 3 and Month 6 9. Working memory is measured using a 2-back working memory task at Baseline, Month 3 and Month 6 10. Selective attention and motor response inhibition are measured using a Go/No-Go task at Baseline, Month 3 and Month 6 11. Sustained attention and vigilance on detection of rare signals are measured using the Mackworth Clock task at Baseline, Month 3 and Month 6 12. Continuous performance variables are measured using a CPT task at Baseline, Month 3 and Month 6 Process Evaluation 1. Parent enablement will be measured using the Patient Enablement Instrument (PEI) at Baseline, Month 3 and Month 6 2. Intervention acceptability will be measured using the Theoretical framework of acceptability (TFA) at Month 3 3. Engagement with the intervention will be measured by intervention usage over the 6-month intervention period Qualitative Interviews Qualitative process interviews will be carried out with 25-30 trial participants to provide in-depth understanding of participant experiences within the trial and provide a better understanding of factors that may influence eng
