Resumen
ANDREU, Mauro et al. Cross-cultural adaptation and content validity of a questionnaire to explore Argentine physical therapists’ perspectives on using contextual factors in musculoskeletal pain. Argentinian j. respiratory physical therapy [online]. 2022, vol.4, n.2, pp.20-31. ISSN 2618-4095. http://dx.doi.org/10.58172/ajrpt.v4i2.207.
Objective:
To describe the cross-cultural adaptation and content validity process of the Italian version of a questionnaire into Argentine Spanish to explore Argentine physical therapists´ knowledge, beliefs and attitudes towards the use of contextual factors (CFs) in musculoskeletal pain.
Materials and method:
This study comprises a mixed model including qualitative and quantitative methods through three stages: cross-cultural adaptation, content validity, and pilot testing. For content validity, a two-round modified Delphi method was applied. Content validity index (CVI), content validity ratio (CVR), and modified Kappa were calculated. Pilot testing was performed to confirm the feasibility and content validity of the final version.
Results:
Thirty physical therapists participated in the study. The translation and cross-cultural adaptation process was conducted following the recommended guidelines, and the new version maintained the main dimensions of the original questionnaire. According to the content validity assessment, performed by an expert panel and through cognitive interviews, the items of the revised version were clear, relevant, and comprehensive for the Argentine context. The results of the quantitative content validity analysis showed that the CVI, CVR, and Kappa values were equal to 1.0.
Conclusion:
Through a systematic and iterative approach, the cross-cultural adaptation and content validity process showed that the questionnaire was clear, relevant, and comprehensive to allow further research on its psychometric properties.
