目的：阻塞性睡眠呼吸暂停（Obstructive sleep apnea，OSA）是多民族人群中常见的睡眠障碍. OSA患者的健康相关生活质量（HRQOL）受损。研究设计和设置：106名中国OSA患者的横断面样本和51名香港患者的纵向样本完成了一项中国的研究，（广东话）版本，以评估其可接受性、分级假设、信度、效度及反应性。结果：97%的受试者理解该工具并认为其相关。内部一致性、重测信度、项目量表的聚合效度、区分效度和结构效度均为良好到优秀。结构效度与SF-36分量表得分显著相关。然而，因素分析显示，只有日常功能和症状领域的项目都加载在假设的量表。纵向数据显示，SAQLI是更敏感的SF-36治疗后的变化。结论：因此，这个版本的SAQLI是一个可接受的，心理测量学有效的，并响应HRQOL措施，用于评估中国OSA患者的疾病和治疗效果的影响。(C)2004爱思唯尔公司All rights reserved.
Objective: Obstructive sleep apnea (OSA) is a common disorder in many ethnic populations. Patients with OSA have impaired health-related quality of life (HRQOL). No sleep apnea-specific HRQOL measure has been validated in Chinese patients.Study Design and Setting: A cross-sectional sample of 106 Chinese OSA patients and a longitudinal sample of 51 patients in Hong Kong completed a Chinese (Cantonese) version of SAQLI for assessment of its acceptability, scaling assumptions, reliability, validity, and responsiveness.Results: The instrument was understood and seen as relevant by 97% of subjects. Internal consistency, test-retest reliability, item-scale convergent validity and discriminatory validity, and construct validity were good to excellent. Construct validity was confirmed by significant correlations with SF-36 subscale scores. However, factor analysis showed that only items of daily functioning and symptom domains all loaded on the hypothesized scales. Longitudinal data showed that SAQLI was more responsive than SF-36 to changes after treatment.Conclusion: Hence, this version of SAQLI was an acceptable, psychometrically valid, and responsive HRQOL measure for evaluating impact of illness and treatment effectiveness in Chinese OSA patients.
