ABSTRACT
OBJECTIVES:
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.METHODS:
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.RESULTS:
There was a final sample of 453 children (53.6% girls), with a mean age of 9.45 years (SDâ¯=â¯1.44). The content validity showed a CVIâ¯≥â¯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 kâ¯=â¯0.740 for the Knowledge dimension and ICCâ¯=â¯0.754 for the Food Practices dimension. The internal consistency showed αâ¯=â¯0.589 for the Knowledge dimension and αâ¯=â¯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.CONCLUSION:
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.Palavras-chave
