Abstract
Physical literacy is a multidimensional construct encompassing physical competence, motivation, confidence, knowledge, and understanding, enabling individuals to engage in lifelong physical activity. This study aimed to adapt the Physical Literacy Scale for Adults (PLAS), originally developed by Naylor, et al. (2024), into Turkish and to evaluate its psychometric properties. The study used a convenience sampling method to include 454 adult participants (40.1% female, 59.9% male; mean age = 30.38 years). The translation process employed the translation–back translation technique, ensuring semantic and conceptual equivalence. Construct validity was examined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while internal consistency was assessed using Cronbach's alpha. The EFA revealed a five-factor structure—Motivation, Social, Confidence, Physical (Coordination and Strength), and Knowledge—explaining 64.64% of the total variance. The CFA results indicated acceptable model fit (χ²/df = 2.062, RMSEA = .06, CFI = .90, GFI = .85, SRMR = .07). Cronbach's alpha coefficients ranged from .76 to .87 across subscales, with an overall reliability of .88. These findings suggest that the Turkish version of PLAS is a valid and reliable instrument for assessing physical literacy in adult populations.
