Abstract：
The purpose of this study was to investigate psychometric properties of the Greek translation of Pittsburgh Sleep Quality Index (GR-PSQI) in a Greek chronic non-specific low back pain (CNSLBP) sample, thus, providing insight on its clarity and acceptability as a widely used sleep assessment tool in clinical practice. Asymptomatic volunteers (n = 73) and CNSLBP volunteers (n = 47), participated in the study. For the assessment of construct validity, the known-groups method was used. Thus, all the participants (asymptomatic and CNSLBP) completed the GR-PSQI. For the assessment of concurrent validity, the CNSLBP participants additionally completed the following validated questionnaires for depression, insomnia and sleep quality: Beck Depression Inventory Questionnaire (BDI), Insomnia Severity Index (ISI), and Sleep Quality Numeric Rating Scale (SQNRS). For the assessment of test-retest reliability, the CNSLBP participants completed the GR-PSQI a second time, one week after the first time. The results showed excellent test-retest reliability (ICC = 0.969, SEM = 0.90, SDD = 2.49%) and internal consistency (Cronbach α = 0.985), moderate to good concurrent validity (from r = 0.556 to r = 0.860) among PSQI, BDI, SQNRS, and ISI, as well as excellent construct validity (p = 0.000) between the two groups. The Greek translation of PSQI could be a valuable tool for Greek healthcare professionals in both clinical and research environments.
摘要：
这项研究的目的是调查希腊慢性非特异性下腰痛（CNSLBP）样本中匹兹堡睡眠质量指数（GR-PSQI）的希腊语翻译的心理测量学特性，因此，提供其作为临床实践中广泛使用的睡眠评估工具的清晰度和可接受性的见解。无症状志愿者（n=73）和CNSLBP志愿者（n=47），参与研究。对于结构效度的评估，使用已知组方法。因此，所有参与者(无症状和CNSLBP)均完成GR-PSQI.对于并发有效性的评估，CNSLBP参与者还完成了以下经过验证的抑郁症问卷，失眠和睡眠质量：贝克抑郁量表(BDI)，失眠严重程度指数（ISI），和睡眠质量数字评定量表(SQNRS)。对于重测可靠性的评估，CNSLBP参与者第二次完成了GR-PSQI，一周后的第一次。结果显示了优异的重测可靠性(ICC=0.969,SEM=0.90,SDD=2.49%)和内部一致性(Cronbachα=0.985),PSQI中中等到良好的并发有效性(从r=0.556到r=0.860)，BDI,SQNRS,还有ISI,以及良好的结构效度(p=0.000)。PSQI的希腊语翻译可能是临床和研究环境中希腊医疗保健专业人员的宝贵工具。
