To determine the reliability and validity of a 10-item questionnaire, the Food Label Literacy for Applied Nutrition Knowledge questionnaire.
Participants were elementary school children exposed to a 90-minute school-based nutrition program. Reliability was assessed via Cronbach α and intraclass correlation coefficient (ICC). Validity was assessed comparing the questionnaire's food choices using an objective metric of nutrition quality, the Overall Nutritional Quality Index (ONQI), via t test. Statistical significance was set at .05.
Four hundred ninety-nine children participated, 51% were female, and the average age was 8.6 (± 0.9) years. Cronbach α = .77 and ICC = 0.68 (between administrations) were observed. ONQI scores of correct responses were significantly higher when compared to the ONQI scores of incorrect responses (27.4 ± 9.4 vs 16.2 ± 9.4; P = .01).
The Food Label Literacy for Applied Nutrition Knowledge questionnaire was found to be both reliable and a valid measure of food label literacy in children taught the Nutrition Detectives program.

    ABSTRACT: Identification of low levels of health literacy is important for effective communication between providers and clients. Assessment instruments for general health literacy are inadequate for use in nutrition education encounters because they do not identify nutrition literacy. The primary objective of this 2-part study was to assess content validity for the Nutrition Literacy Assessment Instrument (NLAI). This study included a 35-item online survey of registered dietitians (134 of whom answered all questions) and a pilot study in which 5 registered dietitians used the NLAI among 26 clients during nutrition education consultations. To assess agreement with the NLAI by survey participants, we used the following scale: "necessary" (70% agreement), "adequate" (80% agreement), or "good" (90% agreement); comments were analyzed by using content analysis. For the pilot, we made comparisons between subjective assessments, the Rapid Estimate of Adult Literacy in Medicine (REALM), and the NLAI. Registered dietitians also completed a postpilot-study survey. For the online survey, we found good agreement (average, 89.7%) for including each section of the NLAI. All sections accomplished their purpose (average, 81.5%). For the pilot, REALM and NLAI correlation (r = 0.38) was not significant; the subjective assessment of clients by dietitians and NLAI lacked agreement 44% of the time, and registered dietitians provided instruction on deficient knowledge and skills identified by the NLAI 90% of the time. The NLAI is a content-valid measure of nutrition literacy. Additional validation of the NLAI is important because an objective instrument is needed for identifying nutrition literacy, a construct that appears to be different from health literacy.

    ABSTRACT: Objectives: We assessed the feasibility of a 15-week nutrition education, physical activity, and media literacy program for children living in urban family homeless shelters. Methods: We developed a qualitative monitoring tool to evaluate program process and impact at 2 shelter sites in the Bronx, New York, from 2009 to 2012. Facilitators recorded indications of participants' understanding of intended messages and demonstrations of changes in attitudes and behaviors. Comments, insights, and actions were recorded as they occurred. Facilitators also documented barriers to delivery of content and activities as intended. We used content analysis to examine data for patterns and identify themes. Results: A total of 162 children participated at the 2 shelter sites. Analysis of qualitative data yielded 3 themes: (1) children's knowledge and understanding of content, (2) children's shift in attitudes or intentions, and (3) interpretations through children's life experience. Food insecurity as well as shelter food service and policies were important influences on children's choices, hunger, and sense of well-being. Conclusions: Children's experiences highlighted the need to advocate for shelter policies that adequately provide for children's nutritional and physical activity requirements and foster academic development.
