Turkish Validation of the Adult Nutrition Literacy Tool

Turkish Validity and Reliability Study of the Adult Food and Nutrition Literacy Assessment Tool

This study evaluated the validity and reliability of the Food and Nutrition Literacy Assessment Tool (FNLAT) in a sample of 849 Turkish adults. Reliability was tested using Cronbach's alpha, test-retest, and Pearson correlation, while construct validity was analyzed via factor analysis. Data were processed with SPSS and AMOS software.

Study Overview

• Status: Completed
• Conditions: Nutrition

Detailed Description

Aim: The aim of this study is to evaluate the validity and reliability of the Food and Nutrition Literacy Assessment Tool in Turkey.

Subject and Methods: The study included 849 individuals aged 19-64 years (316 males, 563 females). A questionnaire containing socio-demographic characteristics and the " Food and Nutrition Literacy Assessment Tool (FNLAT)" and " General Nutrition Knowledge Questionnaire (GNKQ)" were used as data collection tools. Test-retest was performed on 60 individuals at 3-week intervals. Cronbach's alpha, test-retest, and Pearson correlation analyses were conducted to assess the reliability of the scale. The construct validity of the scale was determined using explanatory factor analysis. The data were analyzed using the SPSS (Statistical Package for Social Sciences) for Windows 25.0 and AMOS 21 programs.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
General Nutrition Knowledge Questionnaire (GNKQ) Assessment	The General Nutrition Knowledge Questionnaire was developed to measure general nutrition knowledge, with Turkish validity and reliability established. This questionnaire consists of 35 questions in four sub-components: nutrition recommendations (11 questions), nutrition knowledge (70 questions), food selection (11 questions), and diet-disease relationship (35 questions). Each correct answer within these sub-components is scored as '1,' while incorrect and unsure responses are scored as '0.' The total score ranges from a minimum of 0 to a maximum of 127, with higher scores indicating a greater level of nutrition knowledge. Permission was obtained from the authors	Basaline
Food and Nutrition Literacy Assessment Tool (FNLAT) Assessment	The Food and Nutrition Literacy Assessment Tool was designed to measure food and nutrition literacy, with an internal validity index of ≥90% confirming its content validity. The tool includes six factors: one in the knowledge domain (nutrition knowledge) and five in the skills domain (functional skills, interactive skills, advocacy, critical information analysis, and food label reading skills). Confirmatory factor analysis indicated acceptable model fit indices, validating the construct of FNLAT. Cronbach's Alpha and intraclass correlation coefficient (ICC) values confirmed the internal consistency and stability over time. Scoring: FNLAT scores are calculated by summing raw scores for each subscale or the total, then converting them to a 0-100 scale, where higher scores indicate greater food and nutrition literacy.
