RESUMO

Diabetes is a public health problem. In Brazil, its prevalence is of 7,6% and it is included among the ten major mortality causes. Studies have shown that the appropriate glycemic control may either prevent or delay complications related to the disease, but the lack of adherence to treatment is high. Recently, self-efficacy has been pointed in literature as a predictor of health behaviors, especially for diabetes. Hence, there is an association between adherence to treatment and self-efficacy levels. Due to this reason, it is important to have an instrument adapted and validated for brazilian population, which was the objective of the present study: to adapt and validate IMDSES scale to brazilian reality. The original instrument is American and evaluates self-efficacy in the general management of diabetes, diet, and insulin. The sample comprised 213 patients carrying type 1 diabetes. The analysis of the major components, identified three subscales (diet, insulin and general management) which accounted for 53% of variance. Cronbachs α coefficient, used to evaluate reliability, was, respectively: diet subscale α=0,83,insulin α=0,92 and general management α=0,78. Criteria validity was investigated by two parameters: glycosilated 2 hemoglobin, through which it was possible to show a significant association with self-efficay in the insulin subscale (p=0,04), and adherence variable, that was significantly associated to self-efficacy in two subscales (p<0,05). Temporary stability of the instrument was not verified in a subscale. It was concluded that the instrument possesses appropriate psychometric properties to be used on its proposed goal.
