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.
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.
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.
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.
本研究旨在为巴西用户翻译和跨文化调适胰岛素输送系统评定问卷（IDSRQ），并对其进行测量评估。
采用前瞻性翻译、综合、回译、专家委员会评估、预测试和验证的方法进行研究。我们遵循了测量工具翻译和跨文化调适的国际准则。验证数据提供了有关 IDOSRQ 信度（内部一致性、重测）和结构有效性的信息。
专家评估的内容验证成功，内容效度指数平均为 0.87（±0.2）。IDSRQ 的验证研究共纳入 113 例 T1DM 患者，其中男性占 46%，平均年龄为 32.61（±12.59）岁，糖尿病诊断时的平均年龄为 17.51（±12.41）岁。该量表具有良好的内部一致性（克朗巴赫 α =0.786）。通过计算组内相关系数 0.885（0.834-0.921）对仪器的可靠性进行了分析，这表明所有指标的一致性都足够高。
经翻译和跨文化调适后的巴西葡萄牙语版 IDSRQ 可用于评估巴西 T1DM 患者的健康相关生活质量（HRQOL）和胰岛素输送系统的治疗偏好。
