简介睡眠质量指数（PSQI）是一种广泛使用的标准化工具，用于评估临床和研究环境中的睡眠质量。本研究的目的是翻译成僧伽罗语的PSQI和验证使用相结合的定性和定量的approach.Methods每五个病人年龄在18-60岁谁参加了三级保健医院的门诊部被招募。PSQI采用定性和定量相结合的方法翻译成僧伽罗语。内部一致性采用Cronbach’s alpha进行测量。结构效度进行了评估，通过比较患者谁被确定为有抑郁症，根据流行病学研究中心抑郁量表（CES-D）和那些没有抑郁disorder.Results 46例抑郁症的参与者进行了比较，159名非抑郁症对照组的得分。抑郁症患者PSQI 5个分量表的平均得分均显著高于对照组。因子分析确定了一个单一的组成部分，解释53.53%的方差。Cronbach的α为0.85表示一个高的内部consistency.Conclusions PSQI的僧伽罗语翻译是一个有效的和可靠的工具，以评估睡眠质量。
Introduction Pittsburg Sleep Quality Index (PSQI) is a widely used standardized instrument to assess sleep quality in clinical and research settings. Objective of the study was to translate the PSQI into Sinhala language and validate using a combined qualitative and quantitative approach.Methods Every fifth patient aged 18-60 years who attended the out-patients department of a tertiary care hospital was recruited. PSQI was translated into Sinhala using a combined qualitative and quantitative approach. Internal consistency was measured using Cronbach's alpha. Construct validity was assessed by comparing the scores in patients who were identified as having depressive disorder according to the Centre for Epidemiologic Studies Depression Scale (CES-D) and those without depressive disorder.Results Forty-six participants with depression were compared with 159 non depressed controls. Mean PSQI component scores were significantly higher in depressed patients in 5 components. Factor analysis identified a single component explaining 53.53% of the variance. Cronbach's alpha of 0.85 indicated a high internal consistency.Conclusions The Sinhala translation of the PSQI is a valid and reliable tool to assess sleep quality.
