Abstract: <h4>Objective</h4>There is a paucity of sleep questionnaires that have been psychometrically validated for use in school-aged children. Due to the limitation regarding the psychometric properties and the great variety in question design, there remains a need for a robust omnibus questionnaire that assesses sleep problems in community populations. This study aimed to develop such a questionnaire for school-aged children by assessing the construct validity and reliability of a questionnaire based on a combination of children's sleep domains from two frequently used and validated questionnaires (Habits Questionnaire and Sleep Disorders Scale for Children) and author devised questions.<h4>Patients/methods</h4>Parents of 1904 children aged 5-10 years (mean 7.7 ± 1.7 years) from 32 elementary schools in Adelaide, South Australia, completed the questionnaire.<h4>Results</h4>Principal axis factoring revealed six unique sub-scales--Sleep Routine, Bedtime Anxiety, Morning Tiredness, Night Arousals, Sleep Disordered Breathing, and Restless Sleep--containing a total of 26 items. Internal consistency for sub-scales were moderate to strong (range α = 0.6-0.8) and test-retest reliability was adequate (>0.4). T-score cut-offs were devised for age and sex.<h4>Conclusion</h4>The new questionnaire provides a robust set of sleep problem sub-scales which can be used for assessment of sleep concerns in a community sample as well as provide for optimal analysis of associations with other measures of childhood daytime functioning such as neurocognition and behaviour.
