ABSTRACT
ABSTRACT Objective The aim of this study was to translate and cross-culturally adapt the Insulin Delivery System Rating Questionnaire (IDSRQ) for Brazilian users. Validation and reliability analysis of measures were also performed. Materials and methods Methodological study comprising the following stages forward translation, synthesis, back-translation, assessment by Expert Committee, pre-test and validation. International guidelines for translation and cross-cultural adaptation of measurement tools were followed. Validation data provided information about reliability (internal consistency, test-retest) and construct validity of the IDSRQ. Results Content validation by Experts' assessment was successful, with a mean Content Validity Index of 0.87 (±0.2). The IDSRQ validation study involved 113 T1DM patients, 46% male, mean age 32.61 (±12.59) years and mean age at diagnosis of diabetes of 17.51 (±12.41). The scale presented good internal consistency (Cronbach's alpha =0.786). The reliability analysis of the instrument was conducted by calculating the Intra-class Correlation Coefficient 0.885 (0.834-0.921), which indicated adequate concordance in all measures. Conclusion The translated and cross-culturally adapted Brazilian Portuguese version of the IDSRQ may be used to assess health-related quality of life (HRQOL) and treatment preferences for insulin delivery systems in T1DM Brazilian patients.
