Daily parent/teacher ratings of behaviour and sleepiness were obtained. Mixed linear modelling was used to explore associations between total sleep time and daytime naps and behaviour.Results: Sleep in children with SMS was characterised by shorter total sleep time (TST), extended night waking, shorter sleep onset, more daytime naps and earlier morning waking compared to the TD group. Considerable inter-daily and inter-individual variability in sleep quality was found in the SMS group, so caution in generalising results is required. An expected inverse association between age and TST was found in the TD group, but no significant association was found for the SMS group. No between group differences in sleep hygiene practices were identified. A bidirectional negative association between TST and nap duration was found for the SMS group. In the SMS group increased afternoon sleepiness was associated with increased irritability (p=.007) and overactivity (p=.005).Conclusion: These findings evidence poor sleep quality in SMS and the need to implement evidence-based interventions in this population.",
