Factorial Validity of the Delta Healthy Eating Attitudes Scale Related to Diet Quality
Nutrition and Food Systems
Objectives: The objective of this study was to establish factorial validity of decisional balance (DB), self-efficacy (SE) and social support (SS) psychosocial constructs and convergent validity related to diet quality. Methods: A sample (N = 319) of predominantly African-American women from the Mississippi Communities for Healthy Living intervention completed the Delta Healthy Eating Attitudes Scale (DHEAS) and diet questionnaires in 2011. Convergent validity was used to evaluate Diet Quality (DQ) DB, DQSE, DQSS latent variables and diet quality relationships. Results: Factor loadings and model fit indicators suggested latent constructs were reliable. DQDB and DQSE were associated with diet quality (r = .19-.27, p < .001), but not DQSS. Conclusions: DHEAS is a reliable, composite method to represent diet quality psychosocial constructs compatible with available diet quality measurements.
