Year: 2025

Type: article

Abstract: Background: The increasing global prevalence of asthma necessitates effective disease management, with patients and their families playing a central role. Enhancing health literacy (HL) among caregivers is critical to improving asthma outcomes. Purpose: This study aimed to validate the Arabic version of the Asthma Numeracy Questionnaire (Ar-ANQ) to address the gap in HL assessment tools for Arabic-speaking populations. Patients and Methods: A total of 400 parents of children with asthma completed the Ar-ANQ at an outpatient respiratory clinic. Confirmatory factor analysis (CFA) and Rasch analysis were employed to evaluate the psychometric properties of the instrument. Results: CFA supported the unidimensional structure of the Ar-ANQ, with excellent model fit indices (χ²/df = 4.6, SRMR = 0.02, CFI = 0.99, GFI = 0.99, TLI = 0.96) and high internal consistency (Cronbach's α = 0.82). Rasch analysis further demonstrated psychometric robustness, with high person and item separation reliabilities (0.74 and 0.99, respectively) and acceptable infit and outfit statistics. Conclusion: The Arabic version of the Asthma Numeracy Questionnaire (Ar-ANQ) is a reliable and valid instrument for assessing health literacy among parents of children with asthma.
