Journal Club: Reliability and Construct Validity of a Questionnaire

Using valid and reliable outcome measures is critical to assessing the effectiveness of nutrition education programs but, oftentimes, measures do not exist for the outcomes of interest. In this presentation, we will discuss psychometric analysis methods for validity and reliability testing of infant feeding education questions for the Expanded Food and Nutrition Education Program (EFNEP). Specifically, we will discuss why we selected the particular construct validity and reliability tests used, how the research was designed for each test, and the strengths and possible limitations of each test. Finally, we will share how we analyzed and reported our results for the construct validity and reliability tests and the lessons we learned from this psychometric analysis study.
