This paper outlines the development and psychometric evaluation of the Manifestations and Vulnerabilities of Behavioural Insomnia in Childhood Scale (MAVBICS), an instrument intended to assess the manifestations of, and factors underpinning, child behavioural insomnia. The MAVBICS comprises two sections: a more general sleep and bedtime information section (Section 1), and a psychometric measure of six theoretically derived factors that underlie, contribute to, and are manifestations of, child sleep problems (Section 2), that is the focus of this research. Study 1 comprised an exploratory factor analysis of Section 2 items (EFA; n = 328 parents of children aged 3-12 years), with a final 25 items found to load highly onto 6 factors; Sleep Maintenance Problems (4 items, α = 0.88), Co-Sleeping Behaviours (4 items, α = 0.93), Bedtime Routines (5 items, α = 0.82), Bedtime Resistance (5 items, α = 0.88), Bedtime Worries (3 items, α = 0.85) and Bedtime Fears (4 items, α = 0.86). Study 2 comprised a confirmatory factor analysis (CFA) of Section 2 items and tests of convergent validity (n = 313), with results confirming the factor structure and providing evidence for convergent validity through correlations in expected directions between MAVBICS scores and other sleep, anxiety and behaviour measures. Study 3 tested the test-retest reliability of Section 2 items (n = 53), and found support for the temporal stability of the MAVBICS over a 2-week period. Overall, the results provide strong preliminary evidence for the validity of the MAVBICS total score and its subscales, although the Bedtime Routines subscale may be less useful.
本文概述了儿童行为性失眠的表现与易感性量表（MAVBICS）的开发及心理测量学评估。该量表旨在评估儿童行为性失眠的表现及相关因素。MAVBICS由两个部分组成：一个更通用的睡眠和就寝时间信息部分（第1部分），以及一个对六个理论推导因素的心理测量部分（第2部分），这六个因素是儿童睡眠问题的基础、成因及表现，也是本研究的重点。研究1对第2部分的项目进行了探索性因素分析（EFA；n = 328名3至12岁儿童的父母），最终发现25个项目高度载荷于6个因素上：睡眠维持问题（4个项目，α = 0.88）、同睡行为（4个项目，α = 0.93）、就寝常规（5个项目，α = 0.82）、就寝抗拒（5个项目，α = 0.88）、就寝担忧（3个项目，α = 0.85）和就寝恐惧（4个项目，α = 0.86）。研究2对第2部分的项目进行了验证性因素分析（CFA）和收敛效度检验（n = 313），结果证实了因素结构，并通过MAVBICS分数与其他睡眠、焦虑和行为测量指标之间预期方向的相关性为收敛效度提供了证据。研究3测试了第2部分项目的重测信度（n = 53），并发现MAVBICS在两周内具有时间稳定性。总体而言，研究结果为MAVBICS总分及其子量表的效度提供了有力的初步证据，尽管就寝常规子量表可能用处较小。
