旨在改善饮食行为的健康促进干预措施经常将自我效能作为一种促进行为改变的结构。本文介绍了建立儿童健康食品选择自我效能感量表的心理测量特性的研究结果。作为为儿童和青少年心血管健康试验（CATCH）开发仪器的一系列试点研究的一部分，收集了三年级和四年级学生的数据（n = 1,127）。进行数据分析以估计内部一致性、重测信度、析因效度和标准相关效度。结果显示饮食自我效能量表的内部一致性估计是可接受的（系数α = 0.84）。自我效能感与儿童通常的食物选择密切相关，约占方差的34%（多重R = 0.58）。研究结果支持使用这种工具来评估针对营养行为的干预方案，并用于确定自我效能感与饮食行为或相关结构之间关系的研究。
Health promotion interventions intended to improve dietary behavior frequently incorporate self-efficacy as a construct to enhance behavior change. This paper presents results from a study to establish psychometric properties of a scale to measure children's self-efficacy for selecting healthful food. As part of a series of pilot studies to develop instrumentation for the Child and Adolescent Trial for Cardiovascular Health (CATCH), data were collected on third and fourth grade students (n = 1,127). Data analyses were conducted to estimate internal consistency, test-retest reliability, factorial validity, and criterion related validity. Results revealed acceptable estimates of internal consistency for the dietary self-efficacy scale (coefficient alpha = .84). Self-efficacy was strong associated with the children's usual food choices, accounting for about 34% of variance (Multiple R = .58). Findings support using such an instrument for evaluating intervention programs addressing nutrition behavior and for studies to determine the association of self-efficacy to dietary behavior or related constructs.
