Reliability and Validity of a Nutrition Self-Efficacy Scale
Abstract
Self-efficacy is a powerful predictor for some health behaviors. The purpose of this study was to examine the reliability and validity of a nutrition self-efficacy scale measuring knowledge, skills, and motivation associated with low-fat eating. The self-administered surveys were completed by 263 university students. The Nutrition Self-Efficacy Scale and subscales demonstrated high reliability. The results of the profile analysis were consistent with theory, providing support for scale validity. Measuring outcomes beyond knowledge can demonstrate the impact of nutrition curriculum and interventions.
