Valid evaluation tools are needed, particularly for low‐literate participants of federal food assistance and education programs. Our objective is to provide evidence of convergent validity for a 9‐item pictorial vegetable behavioral assessment for use by these federal programs. Parents (n=144) from Head Start and Supplemental Food for Women, Infants and Children [WIC] provided parent self‐administered Healthy Kids (HK) and three child 24‐hour diet recalls. The 9‐scale [recoded to the healthy direction] produced an alpha of .83. This scale was positively related to a sum of the volume of vegetables in cup equivalents for dinner from the food logs. Linear regression identified the strongest predictor items using cup equivalents as the outcome [r=.54, p<.00001]. Spearman correlations produced significant unweighted results [r=.40, p<.0001]. The scale was significantly related to hypothesized nutrients: folate, Vitamin C, soluble fiber, beta‐carotene. The resulting short pictorial assessment with low‐respondent burden may be useful in evaluating vegetable behaviors among low‐literate program participants.
