The objective of this study was to report the construct validity and internal consistency reliability of the Food Behavior Checklist modified for children (FBC-MC), with low-income, Youth Expanded Food and Nutrition Education Program (EFNEP)-eligible children.
Using a cross-sectional research design, construct validity was assessed using confirmatory factor analysis (weighted least squares method), and internal consistency reliability for 3 subscales was assessed using Cronbach alpha.
Ninety-seven children from low-income families completed the FBC-MC. Indicator tests suggest adequate model fit (comparative fit index = 0.962; root mean square error of approximation = 0.064) and item factor loadings were significant for all subscales (P < .05). The instrument appeared to have adequate reliability for 1 subscale (fruit and vegetable consumption, alpha = 0.67), but not for the other 2 (milk consumption, alpha = 0.43; healthful eating behaviors, alpha = 0.56).
The FBC-MC may be a suitable instrument for evaluating dietary behaviors among Youth EFNEP-eligible children; however, more work is needed to establish internal reliability and criterion validity.
本研究旨在报告儿童食品行为检查表（FBC-MC）的结构效度和内部一致性信度，该检查表适用于低收入、符合青年扩大食品和营养教育计划（EFNEP）条件的儿童。
采用横断面研究设计，使用验证性因子分析（加权最小二乘法）评估结构效度，使用 Cronbach alpha 评估 3 个分量表的内部一致性信度。
97 名来自低收入家庭的儿童完成了 FBC-MC。指标测试表明模型拟合度良好（比较拟合指数=0.962；均方根误差近似值=0.064），所有分量表的项目因子负荷均具有统计学意义（P<0.05）。该工具在一个分量表（水果和蔬菜摄入，α=0.67）上似乎具有足够的可靠性，但在另外两个分量表（牛奶摄入，α=0.43；健康饮食行为，α=0.56）上则不然。
FBC-MC 可能是评估符合青年 EFNEP 条件的儿童饮食行为的合适工具；然而，还需要进一步的工作来建立内部可靠性和效标效度。
