Brazilian version of “The Insulin Delivery System Rating Questionnaire”: translation, cross-cultural adaptation and validation

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, testretest) 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.

Psychometric properties of the Czech version of the Insulin Delivery System Rating Questionnaire

“…As part of the validity, the CVI of the Czech IDSRQ instrument was performed, which reached a value of 0.89. Compared to the study by Coelho et al (2021), this value is higher than the CVI of the Brazilian version of the IDSRQ instrument (0.87).…”

“…The lowest Cronbach's alpha value of 0.42 was for the psychological well-being subscale, and a low Cronbach's alpha value of 0.288 in the same subscale was also reported by Coelho et al (2021). In the study by Coelho et al (2021), the Cronbach's alpha values in the seven subscales ranged from 0.288 to 0.906. The Cronbach's alpha values were similar to the present study (0.42 to 0.92).…”

“…In the original validation study by Peyrot and Rubin (2005), the reliability for a set of respondents with T1DM and T2DM in individual subscales 1-7 was based on Cronbach's alpha values of 0.67-0.92. The results of this study present processed data for respondents with T1DM only, as do the results of the Coelho et al (2021) study. In that study, Cronbach's alpha values ranged from 0.42-0.92.…”

Questionários direcionados ao diabetes mellitus validados para o português do Brasil

“…Neste contexto, a temática Autocuidado, Autogestão, Autogerenciamento e Autoeficácia reuniu 12 publicações disponíveis 13,14,17,20,[25][26][27][31][32][33]36,39 , que abordam os diferentes aspectos relacionados ao tema e demonstram a relevância e a importância do manejo adequado do DM pelo próprio paciente. O uso de instrumentos de medida do autocuidado é uma ferramenta prática que pode facilitar profissionais da saúde para avaliar um construto subjetivo e que não é possível mensurar de forma direta; assim, auxilia e permite mensurações do quanto a pessoa realiza esses comportamentos conforme as recomendações das diretrizes de diabetes 1,2,13,37 .…”

“…No cuidado psicológico dos pacientes, é necessário identificar suas dificuldades em assumir o papel ativo no tratamento do DM para que ele alcance as metas do controle glicêmico e trace ações de saúde que levem à redução do estresse causado pelo DM. Na temática Aspectos psicológicos/Estresse emocional, dois questionários foram identificados para esta finalidade 23,37 A ulceração do pé é a complicação mais comum das pessoas com DM e está associada com altas taxas de morbimortalidade 60,61 . A taxa de incidência de úlceras nos pés entre pessoas com DM ao longo da vida varia de 19% a 34%, com recorrência 40% no primeiro ano e 65% em três anos 62 .…”
