To develop and validate an instrument about nutritional knowledge and feeding practices to be used in children aged 7-11 years, based on the latest Brazilian Food Guide.
Review on the subject; instrument creation; content validity with two groups of judges: first, nutritionists and, after adjustments, a multidisciplinary group (content validity index [CVI]); FACE validity; reproducibility analysis (intraclass correlation coefficient [ICC], level of agreement, and kappa [k]); internal consistency analysis (Cronbach's alpha[α]) and construct validity (Kaiser-Meyer-Olkin and exploratory factorial analysis). The sample was calculated, considering at least ten subjects for each question of the questionnaire.
There was a final sample of 453 children (53.6% girls), with a mean age of 9.45 years (SD = 1.44). The content validity showed a CVI ≥ 0.80 for relevance in 62.3% of the items for nutritionists' group and 100% of the items for the multidisciplinary group, clarity (49.4%, 91.8%), and pertinence (58.8%, 98.4%), respectively. The test-retest showed a level of agreement of 84.3% and k = 0.740 for the Knowledge dimension and ICC = 0.754 for the Food Practices dimension. The internal consistency showed α = 0.589 for the Knowledge dimension and α = 0.618 for the Food Practices dimension. For the construct validity, Kaiser-Meyer-Olkin was 0.724 and exploratory factorial analysis showed a variance of 47.01 with varimax rotation and defined five factors for the Practices Dimension.
The Food Knowledge and Practices Questionnaire (Questionário de Conhecimento e Práticas Alimentares [QCPA]) instrument showed validity and reliability to assess nutritional knowledge and food practices in children aged 7-11 years.
根据最新的巴西食品指南，开发并验证一种适用于 7-11 岁儿童的营养知识和喂养实践的工具。
对该主题进行综述；仪器创建；内容有效性与两组裁判：首先是营养师，然后在调整后，是多学科小组（内容有效性指数 [CVI]）；正面有效性；再现性分析（组内相关系数 [ICC]、一致性水平和kappa [k]）；内部一致性分析（Cronbach 的 alpha [α]）和构念有效性（Kaiser-Meyer-Olkin 和探索性因子分析）。样本量根据问卷的每个问题至少有 10 个被试进行计算。
最终样本为 453 名儿童（53.6%为女孩），平均年龄为 9.45 岁（SD=1.44）。内容有效性显示，营养师组 62.3%的项目相关度 [CVI]≥0.80，多学科组 100%的项目均具有清晰性（49.4%，91.8%）和针对性（58.8%，98.4%）。测试-再测试显示，知识维度的一致性水平为 84.3%，kappa 值为 0.740，食物实践维度的 ICC 值为 0.754。内部一致性显示，知识维度的 alpha 值为 0.589，食物实践维度的 alpha 值为 0.618。对于构念有效性，Kaiser-Meyer-Olkin 为 0.724，探索性因子分析显示实践维度的方差为 47.01，采用最大方差旋转法定义了五个因子。
食物知识和实践问卷（Questionário de Conhecimento e Práticas Alimentares [QCPA]）工具具有有效性和可靠性，可用于评估 7-11 岁儿童的营养知识和食物实践。
