OBJECTIVE
To extend the health-related quality of life assessment literature by examining the reliability and validity of Sizing Me Up in a community sample of nontreatment-seeking overweight and obese children.
METHODS
Participants included 302 students (M age = 10.34) recruited from 6 elementary schools, who completed self-report measures of health-related quality of life and weight-related health.
RESULTS
134 overweight and obese children were included in the analyses to establish validity for the measure. Confirmatory factor analyses supported a 5-factor first-order factor structure with 1 second-order factor representing a total score. Convergent and criterion-related validity was established among overweight and obese children. Estimates of internal consistency for the 5-factor Sizing Me Up factor structure indicated that the subscales are not acceptable outside of a structural equation modeling approach.
CONCLUSION
Outside of a structural equation modeling framework, only the total score appears to be appropriate in this population.
目的
通过考察非治疗性超重和肥胖儿童样本中对自我形象感知量表的信度和效度，来扩展健康相关生活质量评估文献。
方法
参与者包括从 6 所小学招募的 302 名学生（M 年龄=10.34），他们完成了健康相关生活质量和与体重相关健康的自我报告测量。
结果
对 134 名超重和肥胖儿童进行分析以确立该测量方法的有效性。验证性因子分析支持一个 5 因素一阶因子结构，其中 1 个二阶因子代表总分。在超重和肥胖儿童中建立了收敛和标准相关的有效性。5 因素自我形象感知量表因子结构的内部一致性估计表明，在结构方程建模方法之外，这些分量表是不可接受的。
结论
在结构方程建模框架之外，在该人群中似乎只有总分是合适的。
