Occupational Health Literacy Scale: Turkish Validity and Reliability Study.

Background and Purpose: Occupational health literacy is a key determinant of workplace safety and employee well-being, yet Turkish measurement tools are limited. This study aimed to adapt the Occupational Health Literacy Scale (OHLS) into Turkish and evaluate its psychometric properties. Methods: A methodological design was used with 187 jewelry sector employees. The process included forward-backward translation, expert review, and pilot testing. Validity was tested with exploratory and confirmatory factor analyses (CFA), and reliability with Cronbach's alpha, test-retest, and intraclass correlation coefficient (ICC). Results: CFA showed acceptable fit indices (χ²/df = 2.15, comparative fit index = .93, goodness-offitindex = .91, adjusted goodness-of-fit index = .90, root-mean-square error of approximation = .07). Cronbach's alpha was .822, and test-retest confirmed strong stability (ICC = .89). Conclusions: The Turkish OHLS is a valid and reliable tool for assessing occupational health literacy.
