BACKGROUND
Psychometrically robust questionnaires to assess self-reported sleep problems in children are important since sleep problems can have a major impact on child development. The Sleep Self Report (SSR) is a 26-item self-report tool measuring different sleep domains in children aged 7-12 years. This study aims to evaluate the psychometric properties of the SSR and to provide Dutch norm scores.
METHODS
Children aged 7-12 years from the general population were recruited through a professional market research agency. In this population, structural validity was assessed with confirmatory and exploratory factor analyses, internal consistency was assessed with the Cronbach's alpha coefficient and norm scores were provided. Additionally, children attending outpatient sleep clinics (clinical population) were invited to participate. SSR scores of the general population and the clinical population were compared to establish discriminative validity.
RESULTS
In total, 619 children (mean age: 9.94 ± 1.72 years) from the general population and 34 children (mean age: 9.21 ± 1.63 years) from sleep clinics participated. The 1-factor structure of the SSR was not confirmed with factor analysis. Exploratory analyses did also not yield an appropriate multidimensional structure. Internal consistency of the total score was adequate (Cronbach's alpha: 0.76). The total score distinguished the clinical population from the general population (39.07 ± 5.31 versus 31.61 ± 5.31; P < 0.01).
CONCLUSIONS
An appropriate structure of the SSR was not found with factor analyses in this Dutch population. The adequate internal consistency indicates that the total score can be interpreted as a measure of overall sleep problems. The SSR also shows good discriminative validity. We recommend the total score to assess overall sleep problems and item scores to evaluate specific sleep issues and to follow up children's sleep longitudinally, as opposite changes in different item scores may not reflect in the total score. Further research on the development of multidimensional psychometrically sound pediatric sleep self-reports is of major importance.
背景
评估 7-12 岁儿童自我报告睡眠问题的心理测量学上可靠的问卷非常重要，因为睡眠问题会对儿童的发展产生重大影响。睡眠自我报告（SSR）是一种 26 项自我报告工具，用于测量 7-12 岁儿童的不同睡眠领域。本研究旨在评估 SSR 的心理测量特性，并提供荷兰的常模分数。
方法
通过专业的市场研究机构招募了 7-12 岁的普通人群儿童。在该人群中，使用验证性和探索性因素分析评估结构效度，使用克朗巴赫的 alpha 系数评估内部一致性，并提供常模分数。此外，还邀请了在门诊睡眠诊所就诊的儿童（临床人群）参加。将普通人群和临床人群的 SSR 分数进行比较，以建立判别效度。
结果
共有 619 名普通人群儿童（平均年龄：9.94±1.72 岁）和 34 名睡眠诊所儿童（平均年龄：9.21±1.63 岁）参加了研究。SSR 的 1 因素结构未通过因子分析得到证实。探索性分析也没有产生适当的多维结构。总分的内部一致性是足够的（克朗巴赫的 alpha：0.76）。总分能够区分临床人群和普通人群（39.07±5.31 与 31.61±5.31；P<0.01）。
结论
在荷兰人群中，通过因子分析未发现 SSR 的适当结构。足够的内部一致性表明总分可以作为衡量整体睡眠问题的指标。SSR 还具有良好的判别效度。我们建议使用总分评估整体睡眠问题，并使用项目得分评估特定的睡眠问题，并对儿童的睡眠进行纵向随访，因为不同项目得分的相反变化可能不会反映在总分中。进一步研究开发多维心理测量可靠的儿科睡眠自我报告具有重要意义。
