Background: Schools are important arenas for the promotion of critical health literacy (CHL) among adolescents. Key domains of CHL are information appraisal, understanding social determinants of health, and abilities to act on determinants of health. In this paper, we examine the psychometric properties of the Critical Health Literacy for Adolescents Questionnaire (CHLA-Q).
Methods: A cross-sectional survey study was performed at 5 schools in Norway. Respondents included 522 pupils aged 13-15 years old. Confirmatory factor analysis (CFA) was conducted to examine the structural validity. Internal reliability was assessed using ordinal Cronbach's alpha.
Results: The estimated model had acceptable closeness of fit. Five of 6 scales displayed adequate internal reliability.
Conclusion: The results indicate acceptable fit of the CHLA-Q framework and that 5 of the 6 scales are applicable to inform future research and interventions. More research is needed on measurement of the second domain of CHL.
Keywords: adolescents; critical health literacy; measurement; psychometric properties.
