青少年睡眠质量的异质性:基于潜在剖面分析

Heterogeneity in Adolescent Sleep Quality:A Latent Profile Analysis

目的:探索青少年睡眠质量的潜在类型,分析睡眠信念、年龄和性别与睡眠质量潜在类型的关系。方法:采用匹兹堡睡眠质量指数及简式睡眠失功能信念及态度量表对1996名青少年进行调查,运用潜在剖面分析进行异质性检验。结果:(1)青少年睡眠质量存在四种潜在类型:睡眠良好型、日间功能障碍型、睡眠一般型和睡眠不足且低效型。(2)睡眠信念较差的青少年的睡眠质量较差,日间功能障碍组多为女性青少年,睡眠不足且低效组多为年龄较小的青少年。结论:青少年睡眠质量具有明显的分类特征,为预防和干预青少年睡眠质量提供了实证依据。

Objective:The main purpose was to explore the latent profiles of sleep quality in Chinese adolescents,and analyze their associations with sleep belief,age and gender.Methods:A total of 1996 Chinese adolescents were recruited,and they completed the Pittsburgh Sleep Quality Index Scale(PSQI)and a 16-item abbreviated version of the Dysfunctional Beliefs and Attitudes about Sleep Scale(DBAS-16).The data was analyzed with the latent profile analysis.Results:(1)Four latent profiles of sleep quality among adolescents were found:good sleep group,daytime dysfunction group,moderate type group,insufficient and inefficient sleep group.(2)Adolescents with poor sleep beliefs had relatively poor levels of sleep quality;daytime dysfunction group and insufficient and inefficient sleep group were mostly younger adolescents;the daytime dysfunction group was mostly female adolescents.Conclusion:The sleep quality of adolescents has obvious classification characteristics.It provides an empirical basis for the prevention and intervention of adolescent sleep quality.
