Sommaire de l'article

PURPOSE
Assess the psychometric properties of the Self-Efficacy Consumption of Fruit and Vegetable Scale (F/V scale) in African American women.

SETTING
Midwestern Health Maintenance Organization.

SUBJECTS
221 African American women age 40-65 with BMI≥30 MEASURES: F/V scale was compared to eating efficacy/availability subscale reported on the WEL and mean micronutrient intake (vitamins A, C, K, folate, potassium, and beta-carotene reported on 3-day food records.

RESULTS
F/V scale construct validity and internal consistency were assessed and compared to: 1) the original scale validation in Chinese women, 2) WEL scale, and 3) to micronutrient intake from 3-day food records. Total scale scores differed between African American women (μ=1.87+/-0.87) and Chinese (μ=0.41). In a Chinese population, F/V scale factored into two subscales; the F/V factored into one subscale in African American women. Construct validity was supported with correlation between the F/V scale and the eating efficacy WEL subscale (r(2)=-0.336, p=0.000). There was not a significant correlation between dietary consumption of micronutrients representative of fruit and vegetable intake and the F/V scale.

CONCLUSION
The F/V scale developed for Chinese populations can be reliably used with African American women.
