In school-based samples of children, the Children's Eating Attitudes Test (ChEAT) has a four-factor structure; however, previous studies have not examined its factor structure in samples restricted to overweight youth.
The ChEAT was administered to 220 overweight (BMI>or=95th percentile) and 45 at-risk for overweight (BMI 85th-<95th percentile) children and adolescents. Factors were identified by a principal component analysis with varimax rotation. ChEAT factor scores of children with BMI>or=85th percentile were contrasted with those of 152 non-overweight (BMI 5th to <85th percentile) children and adolescents.
Factor analysis generated four subscales described as 'body/weight concern,' 'food preoccupation,' 'dieting,' and 'eating concern.' ChEAT total score, body/weight concern, and dieting subscale scores were positively related to BMI-Z and body fat mass (p's<.05). Compared to non-overweight children, overweight and at-risk for overweight children had higher ChEAT total (9.9+/-7.4 vs. 6.6+/-7.8, p<.001), body/weight concern (3.2+/-3.1 vs. 1.3+/-3.0, p<.001), and dieting (1.8+/-2.2 vs. .8+/-2.3, p<.001) subscale scores.
The previously elucidated factor structure of the ChEAT was primarily supported in a sample of overweight children. The emergence of separate body/weight concern and dieting subscales may relate to these children's experiences with attempted weight reduction.
在以学校为基础的儿童样本中,儿童饮食态度测试(ChEAT)具有四因素结构;然而,以往研究尚未在仅限于超重青少年的样本中检验其因素结构。
对220名超重(BMI≥第95百分位数)和45名超重风险儿童(BMI第85至<第95百分位数)进行了ChEAT测试。通过主成分分析和方差最大化旋转确定因素。将BMI≥第85百分位数儿童的ChEAT因素得分与152名非超重(BMI第5至<第85百分位数)儿童和青少年的得分进行对比。
因素分析产生了四个子量表,分别描述为“身体/体重关注”、“食物专注”、“节食”和“饮食关注”。ChEAT总分、身体/体重关注和节食子量表得分与BMI-Z和体脂量呈正相关(p值<.05)。与非超重儿童相比,超重和超重风险儿童的ChEAT总分(9.9±7.4对6.6±7.8,p<.001)、身体/体重关注(3.2±3.1对1.3±3.0,p<.001)和节食(1.8±2.2对0.8±2.3,p<.001)子量表得分更高。
ChEAT先前阐明的因素结构在超重儿童样本中得到了主要支持。单独的身体/体重关注和节食子量表的出现可能与这些儿童尝试减肥的经历有关。
