Validating and investigating reliability of comprehensive feeding practices questionnaire

ABSTRACT

The present research aims to validate and discuss the reliability of Comprehensive Feeding Practices Questionnaire [CFPQ]. In this cross-sectional study, 150 mothers with 3-6 year old children in the city of Rasht were selected through cluster random sampling from the public and private kindergartens in 2010. After being confident about the translation validity, the degree of validation [content and structure] and validity [test-retest reliability and internal consistency] of the questionnaire was examined. The degree of validation of questionnaire content, except questions 2, 16 and 46, was at a high level and these three questions were omitted. The method of the consistency of factors and total scores of the questionnaire was used to study the validation of structure, which was satisfactory and varied between 0.30-0.72. The validity of questionnaire was examined through test-retest and Cronbach's alpha methods. The Intraclass Correlation Coefficient [ICC] was between 0.80-0.91 and Cronbach's alpha was between 0.80-0.90. In general, the Comprehensive Feeding Practices Questionnaire [CFPQ] was proved to be valid and with respect to the results obtained from the present research, it can be used in the research on child diet
