The reliability and validity of Stunkard's Figure Rating Scale (FRS) as a measure of current body size (CBS) was established in Western adolescent girls but not in non-Western population. We examined the validity and test-retest reliability of Stunkard's FRS in assessing CBS among Chinese adolescents. Methods. In a school-based survey in Hong Kong, 5666 adolescents (boys: 45.1%; mean age 14.7 years) provided data on self-reported height and weight, CBS, perceived weight status, and health-related quality of life using the Medical Outcomes Study Short-Form version 2 (SF-12v2). Height and weight were also objectively measured. Spearman's correlation was used to assess construct validity, concurrent validity and test-retest reliability.
Convergent and discriminant validity were good: CBS correlated strongly with weight and self-reported/measured BMI, but only weakly with SF-12v2. CBS correlated strongly with perceived weight status, showing concurrent validity. Spearman's correlation (r) for CBS was 0.78 for girls and 0.72 for boys indicating good test-retest reliability. Validity and reliability results did not differ significantly between senior and junior grade adolescents.
Our findings support the use of Stunkard's FRS to measure body size among Chinese adolescents.
斯唐卡德体型评定量表（FRS）作为当前体型（CBS）测量工具的信效度已在西方青春期女孩中得到确立，但在非西方人群中尚未确立。我们检验了斯唐卡德FRS在评估中国青少年CBS方面的效度和重测信度。方法。在香港一项基于学校的调查中，5666名青少年（男孩占45.1%；平均年龄14.7岁）提供了关于自我报告的身高、体重、CBS、感知体重状况以及使用医学结局研究简表第2版（SF - 12v2）的健康相关生活质量的数据。身高和体重也进行了客观测量。采用斯皮尔曼相关性分析来评估结构效度、同时效度和重测信度。
聚合效度和区分效度良好：CBS与体重以及自我报告/测量的BMI高度相关，但与SF - 12v2仅微弱相关。CBS与感知体重状况高度相关，显示出同时效度。女孩CBS的斯皮尔曼相关性（r）为0.78，男孩为0.72，表明重测信度良好。高年级和低年级青少年的效度和信度结果无显著差异。
我们的研究结果支持使用斯唐卡德FRS来测量中国青少年的体型。
