Sleep questionnaires
Results of the PROMIS Sleep Disturbance (N=53 self-report, N=65 proxy-report) and Sleep Related Impairment (N=53 self-report, N=65 proxy-report) questionnaires are presented in Table 2. Compared to norm data, parents reported significantly more sleep problems on the Sleep Disturbance questionnaire (mean T=53.7, P< .01). This was not reported by the children themselves (mean T=50.6, P =.64).
Severe sleep disturbance was experienced by 11% of the children compared to 5% in the general population, according to both parent and self-reports (P= 0.03 and P =.04, respectively). Moderate sleep disturbance was also frequently reported by parents: 31% compared to 20% in the general population (P =.03). Rates of severe sleep related impairment were not significantly elevated according to both parents and children themselves. However, moderate sleep related impairment was more prevalent according to parents (42% vs 20%P< .01).
