Evaluation of Factorial Validity and Reliability of a Food Behavior Checklist for Low-Income Filipinos

Abstract

ObjectiveTo examine factorial validity, test-retest reliability, and internal consistency of a Tagalog-language food behavior checklist (FBC) for a low-income Filipino population. MethodsParticipants (n = 160) completed the FBC on 2 occasions 3 weeks apart. Factor structure was examined using principal component analysis. For internal consistency, Cronbach α was calculated. For test-retest reliability, Spearman correlation or intraclass correlation coefficient (ICC) was calculated between scores at the 2 points. ResultsAll but 1 item loaded on 6 factors: fruit and vegetable quantity, fruit and vegetable variety, fast food, sweetened beverage, healthy fat, and diet quality. Cronbach α was .75 for the total scale (range, .39–.76 for subscales). Spearman correlation was 0.78 (ICC, 0.79) for the total scale (range, 0.66–0.80 [ICC, 0.68–0.80] for subscales). Conclusions and ImplicationsThe FBC demonstrated adequate factorial validity, test-retest reliability, and internal consistency. With additional testing, the FBC may be used to evaluate the US Department of Agriculture's nutrition education programs for Tagalog speakers.
