Development and Evaluation of the Infant Feeding Education Questionnaire for the Expanded Food and Nutrition Education Program

Abstract

Develop and evaluate the Infant Feeding Education Questionnaire (IFEQ) to measure the impact of the Expanded Food and Nutrition Education Program (EFNEP) infant-feeding education on knowledge, attitudes, and behavioral intent. Evaluation included content validity testing through expert reviews and cognitive interviews with low-income mothers (n = 37); construct validity using the known-groups technique (n = 679); convergent validity testing using the Infant Feeding Practices Study II questionnaire (n = 66); and test-retest reliability (n = 66). The IFEQ had strong construct validity for knowledge and attitudes; IFEQ scores were significantly higher for the high-knowledge/attitude group (29.6 ± 3.08) than the low-knowledge/attitude group (14.5 ± 5.81; P < .001). The IFEQ failed to show convergent validity. The percent agreement between baseline and retest questions was moderate to high, indicating reliability over time. This study represents the first steps in the development of the IFEQ. There's a need to perform further testing to establish convergent validity and pilot-test the questions following EFNEP infant-feeding education.
