Quality of life (QoL) outcomes are useful in the assessment of physical, mental and social well-being and for informed healthcare decision making. However, few studies have evaluated QoL issues among Asian children due largely to the lack of culturally valid and reliable QoL questionnaires. Hence, we aimed to report the psychometric properties, in particular factor structure, of KINDL (Singapore) questionnaires among school-going children.
Students aged 8-16 years from participating schools were selected by convenience sampling. Subjects self-completed KINDL-Kid (Singapore) and KINDL-Kiddo (Singapore) questionnaires, which were cross-culturally adapted from KINDL (Germany English) for use in Singapore. We evaluated floor and ceiling effects, internal consistency and performed factor analysis.
A total of 328 respondents (mean (SD) age: 9.6 (1.31) years; 67% female; 75% Chinese, 16% Malays, 9% Indians and others) completed KINDL-Kid while 1,026 respondents (mean (SD) age: 14.0 (1.00) years; 82% female; 82% Chinese, 12% Malays; 6% Indians and others) completed KINDL-Kiddo. Mean (SD) TOTAL QoL score was 65.5 (12.76) and 56.6 (11.92) for KINDL-Kid and KINDL-Kiddo, respectively. Floor and ceiling effects were important in five of six KINDL-Kid and two of six KINDL-Kiddo subscales. Reliability coefficients ranged from 0.40 to 0.71 (KINDL-Kid) and 0.44 to 0.84 (KINDL-Kiddo). Factor analysis generated eight and seven factors in KINDL-Kid and KINDL-Kiddo, respectively.
KINDL-Kiddo exhibited good psychometric properties and may be used to assess QoL in this multi-ethnic English-speaking Asian population. However, psychometric properties of KINDL-Kid may need to be improved either by developing new items or modifying existing items.
生活质量（QoL）结果有助于评估身体、心理和社会福祉，以及为明智的医疗保健决策提供依据。然而，由于缺乏文化上有效且可靠的生活质量问卷，很少有研究评估亚洲儿童的生活质量问题。因此，我们旨在报告适用于学龄儿童的KINDL（新加坡）问卷的心理测量特性，特别是因子结构。
通过便利抽样从参与学校中选取8至16岁的学生。受试者自行完成KINDL-Kid（新加坡）和KINDL-Kiddo（新加坡）问卷，这两份问卷是从KINDL（德国英语版）跨文化改编而来，用于新加坡。我们评估了地板效应和天花板效应、内部一致性并进行了因子分析。
共有328名受访者（平均（标准差）年龄：9.6（1.31）岁；67%为女性；75%为华人，16%为马来人，9%为印度人及其他）完成了KINDL-Kid问卷，1026名受访者（平均（标准差）年龄：14.0（1.00）岁；82%为女性；82%为华人，12%为马来人；6%为印度人及其他）完成了KINDL-Kiddo问卷。KINDL-Kid和KINDL-Kiddo的平均（标准差）总生活质量得分分别为65.5（12.76）和56.6（11.92）。在KINDL-Kid的六个子量表中有五个以及KINDL-Kiddo的六个子量表中有两个存在明显的地板效应和天花板效应。信度系数范围为0.40至0.71（KINDL-Kid）和0.44至0.84（KINDL-Kiddo）。因子分析在KINDL-Kid中产生了八个因子，在KINDL-Kiddo中产生了七个因子。
KINDL-Kiddo表现出良好的心理测量特性，可用于评估这个多民族英语亚洲人群的生活质量。然而，KINDL-Kid的心理测量特性可能需要通过开发新项目或修改现有项目来加以改进。
