BACKGROUND
The concept Health related Quality of life (HRQOL) is increasingly recognized as an important health outcome measure in clinical and research fields. The present study attempted to evaluate the psychometric properties of the Sinhala version of the Pediatric Quality of Life Inventory™ 4.0 (PedsQL™ 4.0) Generic Core Scales among adolescents in Sri Lanka.
METHODS
The original US PedsQL™ was translated into Sinhala and conceptually validated according to international guidelines. A cross-sectional study was conducted among 142 healthy school going adolescents (12-14 years), their parents (n = 120) and a group of adolescents with asthma who attended asthma clinics (n = 115). Reliability was assessed using Cronbach's alpha and validity by examining scale structure, exploring inter-scale correlations and comparing across known groups (healthy vs. chronically ill).
RESULTS
The PedsQL™ Sinhala version was found to be acceptable with minimal missing responses. All scales demonstrated satisfactory reliability. Cronbach's alpha for the total scale scores was 0.85 for adolescent self-report while for the parent proxy-report for the healthy group it was 0.86. No floor effects were observed. Ceiling effects were noticed in self-report and parent proxy-report for the healthy group. Overall results of the multi trait scaling analysis confirmed the scale structure with 74% item-convergent validity, 88% item-discriminant validity and an overall scaling success of 72%. Moderate to high correlations were shown among the domains of teen self-report (Spearman rho = .37-.54) and between teen self-report and parent proxy-reports (Spearman rho = .41-.57). The PedsQL™ tool was able to discriminate between the quality of life in healthy adolescents and adolescents with asthma.
CONCLUSION
The findings support the reliability and validity of the Sinhala version of the PedsQL™ 4.0 Generic Core Scales as a generic instrument to measure HRQOL among early adolescents in Sri Lanka in a population setting.
背景
健康相关生活质量（HRQOL）的概念越来越被认为是临床和研究领域中重要的健康结果衡量标准。本研究试图评估斯里兰卡青少年使用的儿科生活质量量表 4.0（PedsQL 4.0）通用核心量表的心理测量特性。
方法
根据国际指南，将原始的美国 PedsQL 翻译成僧伽罗语并进行概念验证。对 142 名健康上学的青少年（12-14 岁）、他们的父母（n=120）和一组在哮喘诊所就诊的青少年哮喘患者（n=115）进行了横断面研究。使用 Cronbach's alpha 评估信度，通过检查量表结构、探索量表间相关性以及比较已知组（健康组与慢性病组）来评估效度。
结果
PedsQL 僧伽罗语版本被认为是可接受的，仅有少量缺失响应。所有量表的可靠性均令人满意。青少年自我报告的总量表得分为 0.85，父母代理报告的健康组得分为 0.86。未观察到地板效应。健康组的自我报告和父母代理报告中均观察到天花板效应。多特质量表分析的总体结果证实了量表结构，具有 74%的项目聚合效度、88%的项目区分效度和 72%的总体量表成功度。青少年自我报告的各个领域之间（Spearman rho=.37-.54）以及青少年自我报告和父母代理报告之间（Spearman rho=.41-.57）显示出中度到高度相关性。PedsQL 工具能够区分健康青少年和哮喘青少年的生活质量。
结论
研究结果支持 PedsQL 4.0 通用核心量表的僧伽罗语版本的可靠性和有效性，是在人群环境中衡量斯里兰卡青少年健康相关生活质量的通用工具。
