Development and Preliminary Validation of Diabetes Adjustment Assessment Scale (DAAS): a New Measure of Adjustment with Type 2 Diabetes.

Abstract

Several adjustment scales are available for Diabetes, but, unfortunately most of them focused on the limited dimensions of diabetes and are not specific for type 2 diabetes. The aim of this study was to develop a multidimensional scale for Diabetes type 2 Adjustment Assessment and to test preliminary validity, reliability and clinical utility of the scale for this population.In this methodological design study, the Diabetes Adjustment Assessment Scale was developed and the psychometric properties of this scale was assessed in patients with Type 2 diabetes. This study included internal consistency, content validity and exploratory factor analysis.1000 patients with type 2 diabetes completed the 45-item Diabetes Adjustment Scale. After eliminating two item, the 43-item measure demonstrated good internal consistency (Cronbach's ?= 0.75). Factor analysis identified eight factors including; reshape (11 questions), seek to acceptance of illness (7 questions), normal life with the disease (6 questions), initial self-management (2 questions), comparing (4 questions), initial imaging of illness (4 questions), return to resources(3 questions), and advanced self- management (6 questions).Considering that validity and reliability indexes of the scale are reported in an appropriate level, it can be used as a valid and reliable tool in measuring level of adjustment with type2 diabetes.
