Abstract

Biphasic sleep, characterized by nighttime sleep plus daytime napping, has demonstrated some cognitive, health and performance impacts when compared with consolidated monophasic sleep. This motivated the development and validation of the Biphasic Sleep Scale, reported in this paper. Scale development involved a literature review, expert input and individual interviews. The 16-item Biphasic Sleep Scale was then administered to an international online sample (n = 6965) alongside well-established validated sleep scales. To ensure a robust evaluation of the Biphasic Sleep Scale, the sample was divided into two parts: with 15% (n = 1000) of the participants allocated to the exploratory analytic phase; and the remaining 85% (n = 5965) reserved for confirmatory analyses. Psychometric evaluation included both exploratory and confirmatory factor analysis, reliability analysis, correlations, network analysis, and item response theory. Exploratory factor analysis indicated a three-factor structure assessing daytime napping as to likelihood, consequences and effect on nighttime sleep. Confirmatory factor analysis largely confirmed this model with no sex invariance. The three-factor structure showed adequate fit. The Biphasic Sleep Scale demonstrated good internal consistency (α = 0.88, Ω = 0.89). Network analysis revealed varying centrality and connectivity of items. Item response theory found items covering a range of biphasic sleep levels. Significant positive correlations with sleep criteria provided evidence for convergent validity. Further testing is warranted to confirm the factor structure, refine model parsimony, and establish clinical utility. With additional validation, it is hoped that the Biphasic Sleep Scale will become a widely utilized tool.

评估双相睡眠量表(BiSS)的心理测量特性:一种新颖的16项自我报告量表。
与巩固的单相睡眠相比,以夜间睡眠加白天小睡为特征的双相睡眠已经显示出一些认知、健康和表现方面的影响。这推动了双相睡眠量表的发展和验证,在本文中报道。量表的开发包括文献回顾、专家意见和个人访谈。然后对国际在线样本(n = 6965)进行16项双相睡眠量表,以及完善的有效睡眠量表。为了确保双相睡眠量表的可靠评估,样本被分为两部分:15% (n = 1000)的参与者被分配到探索性分析阶段;其余85% (n = 5965)留作验证性分析。心理测量学评价包括探索性和验证性因子分析、信度分析、相关分析、网络分析和项目反应理论。探索性因素分析显示了一个三因素结构来评估白天小睡的可能性、后果和对夜间睡眠的影响。验证性因子分析在很大程度上证实了该模型不存在性别不变性。三因子结构吻合良好。双相睡眠量表具有良好的内部一致性(α = 0.88, Ω = 0.89)。网络分析揭示了不同项目的中心性和连通性。项目反应理论发现,项目涵盖了一系列双相睡眠水平。与睡眠标准的显著正相关为趋同效度提供了证据。进一步的测试是必要的,以确认因子结构,完善模型的简约性,并建立临床应用。通过进一步的验证,希望双相睡眠量表将成为一个广泛使用的工具。

期刊介绍: The Journal of Sleep Research is dedicated to basic and clinical sleep research. The Journal publishes original research papers and invited reviews in all areas of sleep research (including biological rhythms). The Journal aims to promote the exchange of ideas between basic and clinical sleep researchers coming from a wide range of backgrounds and disciplines. The Journal will achieve this by publishing papers which use multidisciplinary and novel approaches to answer important questions about sleep, as well as its disorders and the treatment thereof.
