Validity and Reliability of the Turkish Version of Insulin Treatment Appraisal Scale for Type 2 Diabetes Patients

The reason is that negative perceptions of insulin use cause patients to show resistance to starting insulin treatment. Evaluation of diabetes patients' perceptions is thought to allow planning effective attempts to develop self-management and behavioral changes in these patients. The purpose is to evaluate the validity and reliability of the Turkish version of the Insulin Treatment Appraisal Scale. This study is a methodological study. The research sample included a total of 367 patients who received treatment for type 2 diabetes in one university hospital and one private hospital in Turkey between October 2015 and July 2016. The research data were collected with an Introductory Information Form and with the Insulin Treatment Appraisal Scale - Turkish Version fITASTr). For the analysis of the data, Kendall's coefficient of concordance, factor analysis, Cronbach alpha coefficient, Pearson correlation analysis and student t test were used. For the language validity of the scale, the translation-retranslation method was used. As for the content validity, the field experts reached consensus (KW = .114, p = .305). For ITASTr, the item-total score correlation coefficients ranged between .40 and .82. For the whole scale, the Cronbach alpha coefficient was calculated as .80, and the coefficients for the sub-dimensions were calculated as .83 and .64. Based on the results, ITASTr was found to be a valid and reliable tool that can be used to measure insulin-using and non-insulin-using type 2 diabetes individuals' negative and positive perceptions of insulin treatment.
