Objective
Develop, refine, and test psychosocial scales for associations with whole-grain intake.Methods
A cross-sectional survey was conducted in a Minneapolis/St. Paul suburban elementary school with children in fourth through sixth grades (n = 98) and their parents (n = 76). Variables of interest were child whole-grain intake, self-efficacy, outcome expectations, preferences, knowledge regarding whole-grain food, and whole-grain availability at home. Correlation analysis and one-way analysis of variance were used to analyze data.
Results
Internal consistency and test-retest correlation coefficients for child psychosocial scales were modest or acceptable (¦Á = .55-.70). Parents reported a mean of 15 ¡À 7 whole-grain products available at home. Child mean daily intake of total grain was about 8 servings, and intake of products containing whole grain was slightly over 2 servings. Reported home availability and refined-grain intake were significantly related to whole-grain intake, whereas psychosocial variables were not.
Conclusions and Implications
Home availability may be a more important variable associated with whole-grain intake than psychosocial variables.
