Subjective reports of patients with insomnia often show a discrepancy with their objective assessments of sleep. We aimed to assess subjective-objective sleep discrepancy in subjects with insomnia disorder as well as the psychological factors associated with the discrepancy.
This study is a secondary analysis of the baseline data of a randomized controlled study on 110 adults aged 18 years to 59 years with insomnia disorder. Subjective reports on sleep and the objective measures acquired by an overnight polysomnography were used to measure the sleep discrepancy. Smartphone Addiction Proneness Scale (SAPS), Center for Epidemiologic Studies Depression Scale (CES-D), beck anxiety inventory (BAI), and Global Assessment of Recent Stress (GARS) were used to evaluate the psychological factors associated with the sleep discrepancy.
Mean total sleep time (TST) discrepancy of the participants was -81.65±97.41 minutes. Multivariable logistic regression analyses revealed that age (adjusted OR=1.07, 95% CI=1.01-1.13, p=0.027), years of education (adjusted OR=0.69, 95% CI=0.48-0.91, p=0.017), and smartphone addiction proneness (adjusted OR=1.14, 95% CI=1.04-1.27, p=0.008) were independent predictors of TST misperception. Mean sleep onset latency (SOL) discrepancy of the participants was 41.28±45.01 minutes. Only anxiety was an independent predictor of SOL misperception (adjusted OR=1.16, 95% CI=1.05-1.31, p=0.006).
The present study provides empirical evidence to increase our understanding of the various factors that are associated with subjective-objective sleep discrepancy. Screening insomnia patients with smartphone addiction proneness may help predict the potential discrepancy between the patients' subjective reports and objective measures of sleep duration.
失眠患者的主观报告往往与其睡眠客观评估结果存在差异。我们旨在评估失眠症患者的主观 - 客观睡眠差异以及与该差异相关的心理因素。
本研究是一项针对110名年龄在18岁至59岁之间的失眠症成年患者的随机对照研究基线数据的二次分析。通过睡眠主观报告和夜间多导睡眠图获得的客观测量数据来衡量睡眠差异。使用智能手机成瘾倾向量表（SAPS）、流行病学研究中心抑郁量表（CES - D）、贝克焦虑量表（BAI）和近期压力总体评估（GARS）来评估与睡眠差异相关的心理因素。
参与者的平均总睡眠时间（TST）差异为 - 81.65±97.41分钟。多变量逻辑回归分析显示，年龄（调整后的OR = 1.07，95% CI = 1.01 - 1.13，p = 0.027）、受教育年限（调整后的OR = 0.69，95% CI = 0.48 - 0.91，p = 0.017）和智能手机成瘾倾向（调整后的OR = 1.14，95% CI = 1.04 - 1.27，p = 0.008）是TST误判的独立预测因素。参与者的平均睡眠起始潜伏期（SOL）差异为41.28±45.01分钟。只有焦虑是SOL误判的独立预测因素（调整后的OR = 1.16，95% CI = 1.05 - 1.31，p = 0.006）。
本研究提供了实证依据，有助于我们进一步了解与主观 - 客观睡眠差异相关的各种因素。筛查有智能手机成瘾倾向的失眠患者可能有助于预测患者主观报告与睡眠时长客观测量之间的潜在差异。
