| description | ABSTRACT This study cross-culturally adapted the Knowledge of Disease Management-CF-Adolescent (KDM-CF-Adolescent) questionnaire into Brazilian Portuguese and tested its measurement properties. Cross-cultural adaptation followed five standardized steps: translation, consensus on the translated version, back translation, consensus on the back translation version, and application of the final version to 35 adolescent patients aged 11 to 20 years with cystic fibrosis (CF). Due to the COVID-19 pandemic and social distancing measures, the questionnaire was delivered online using the Google Forms platform. Data underwent Rasch analysis using the WINSTEPS software. Since no issues regarding understanding were reported, we made no changes in any of the translated items. KDM-CF-Adolescent divided the sample into two levels of knowledge and the items into three levels of difficulty, leading to person and item reliability indices of 0.67 and 0.81, respectively, and internal consistency of 0.69. All items fit the Rasch model expectations since all infit/outfit and associated z values were within the expected range. Principal component analysis confirmed the existence of two dimensions; however, they did not function as independent scales. Analysis showed no duplication of any content and no floor and/or ceiling effects. The Brazilian Portuguese version of the KDM-CF-Adolescent questionnaire showed satisfactory measurement properties in measuring the knowledge of adolescents with CF about the disease. |
