Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in each of two treatment conditions will receive therapy based on principles of Cognitive Behaviour Therapy for Insomnia. Treatment will be provided by a Psychologist, Clinical Psychologist, or Provisional Psychologist.
1. Sleep restriction: reducing time-in-bed to 30 mins less than the usual average total sleep time. This will be achieved by shifting the child's usual bed time later by 30 minutes.
2. Bedtime restriction: reducing time-in-bed to match usual average total sleep time.
In both of these interventions, participants will attend two therapy sessions (one week apart, 1 hour on each occasion) and will implement their given schedule for a period of two weeks. Adherence to the intervention will be monitored using a 7-day sleep diary and wrist actigraphy.

Behaviour
Comparator / control treatment
Control participants will attend two therapy sessions (one week apart, 1 hour on each occasion). They will receive psycho-education (e.g., information about sleep architecture, REM sleep, circadian rhythms) and implement a regular & consistent bedtime schedule. This will be achieved by calculating their average time-in-bed across the baseline week, and then planning a schedule that involves being in bed for that amount of time each night (using a bed time and rise time that works for their household). This schedule will be implemented for a period of two weeks.
Adherence to the planned sleep schedule will be monitored using a 7-day sleep diary and wrist actigraphy. Treatment will be provided by a Psychologist, Clinical Psychologist, or Provisional Psychologist.
