OBJECTIVE
Examine intentions to buy and eat dark green leafy vegetables (DGLV).

DESIGN
Cross-sectional survey assessing demographics, behavior, intention, and Reasoned Action Approach constructs (attitude, perceived norm, self-efficacy).

SETTING
Marion County, Indiana.

PARTICIPANTS
African American women responsible for buying and preparing household food.

MAIN OUTCOME MEASURE(S)
Reasoned Action Approach constructs explaining intentions to buy and eat DGLV.

ANALYSIS
Summary statistics, Pearson correlations, and multiple regression analyses.

RESULTS
Among participants (n = 410, mean age = 43 y), 76% and 80%, respectively, reported buying and eating DGLV in the past week. Mean consumption was 1.5 cups in the past 3 days. Intentions to buy (r = 0.20, P < .001) and eat (r = 0.23, P < .001) DGLV were positively associated with consumption. Reasoned Action Approach constructs explained 71.2% of the variance in intention to buy, and 60.9% of the variance in intention to eat DGLV. Attitude (β = .63) and self-efficacy (β = .24) related to buying and attitude (β = .60) and self-efficacy (β = .23) related to eating DGLV explained significant amounts of variance in intentions to buy and eat more DGLV. Perceived norm was unrelated to either intention to buy or eat DGLV.

CONCLUSIONS AND IMPLICATIONS
Interventions designed for this population of women should aim to improve DGLV-related attitudes and self-efficacy.
