Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Feasibility outcome: Feasibility and acceptability of the intervention are measured by recording the numbers of eligible participants following screening in proportion to those willing to take part but are ineligible, recruitment rate of both schools and participants, retention rate, assessment and outcome measure completion rate, data completeness, attendance of intervention, incidence of unexpected adverse events throughout the trial, feedback questionnaires post-intervention and interviews post-intervention. | — |
Secondary
| Measure | Time frame |
|---|---|
| Principle clinical outcome: 1. Insomnia will be measured using the Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI). These will be administered at baseline, post-intervention and at 3-month follow-up. Other measures: 2. Sleep patterns will be measured using the Consensus Sleep Diary (CSD) during the week following baseline assessment, post-intervention assessment and at the 3-month follow-up. 3. Symptoms of major DSM-IV anxiety disorders and depression in youth will be measured using the Revised Children's Anxiety and Depression Scale (RCADS) at baseline, post-intervention and at 3-month follow-up. 4. Depressive interpretation bias will be measured using the Ambiguous Scenarios Test for Depression in Adolescents (AST-DA) at baseline, post-intervention and at 3-month follow-up. 5. Cognitive and somatic arousal in the pre-sleep period will be measured using the Pre-Sleep Arousal Scale (PSAS) at baseline, post-intervention and at 3-month follow-up. 6. Dysfunctional beliefs about sleep will be measured using the Short Version of the Dysfunctional Beliefs About Sleep (DBAS) for use with Children at baseline, post-intervention and at 3-month follow-up. 7. Factors associated with behavioural treatments for depression will be measured by the Behavioural Activation for Depression Scale (BADs) - Social and School impairment subscales. This will be administered at baseline, post-intervention and at 3-month follow-up. 8 Frequency and intensity of negative thoughts which may contribute to emotional distress will be measured using the Persistent and Intrusive Negative Thoughts Scale (PINTS) at baseline, post-intervention and at 3-month follow-up. 9. Sleep hygiene practices will be measured using the Cognitive/Emotional subscale of the Adolescent Sleep Hygiene Scale (ASHS) at baseline, post-intervention and at 3-month follow-up. | — |
