Rapid Eating Assessment for Participants [shortened version] scores are associated with Healthy Eating Index-2010 scores and other indices of diet quality in healthy adult omnivores and vegetarians

^aP represents Oneway analysis of variance test; means with different superscripts differ significantly (LSD test, p < 0.05). r represents Pearson correlation; asterisk indicates significant correlation (p < 0.05). HEI-2010 analyses adjusted for energy intake, body weight, and gender. Overall, the absolute average level of correlation for diet quality indices and REAP-S is higher than for diet quality indices and HEI-2010 (0.406 and 0.321 respectively)
