Objective: The purpose of study to adapt the Weight Literacy Scale (WLS) into Turkish and to evaluate its psychometric properties in Turkish adults. Methods: This cross-sectional methodological study included linguistic validation along with comprehensive validity and reliability analyses. Internal consistency was evaluated using Cronbach’s alpha, McDonald’s omega, and item-total correlations.
The test-retest method was applied at a two-week interval to evaluate temporal stability. Test-retest reliability was assessed using the intraclass correlation coefficient (ICC), and construct and structural validity were examined through exploratory factor analyses (EFA) and confirmatory factor analyses (CFA).
Results: Data were collected from 322 participants aged-19-64 years. According to the results of the Kaiser-Meyer-Olkin (KMO) test, the sample size was adequate (KMO=0.784). The Bartlett’s test of sphericity indicated that there were sufficient correlations among the items to conduct factor analysis (χ² =1997.3, p
