PDB36 - Translation, Adaptation And Validation Of The Diabetes Distress Scale For Indonesian Diabetic Outpatients With Various Types Of Complications

Abstract

To translate, adapt and validate the Diabetes Distress Scale (DDS) instrument for Indonesian type 2 diabetes mellitus (T2DM) outpatients with various types of complications. Participants were recruited from four hospitals and two primary healthcare facilities. The procedure of the study included forward and backward translations, an adaptation testing with a small subset of participants, and a validation test. Factor analysis with maximum likelihood estimation and promax rotation was used to investigate the instrument structure. Internal consistency among the items was estimated using Cronbach’s alpha for each of the four domains of the DDS. The instrument form resulting from this study was labeled DDS17 Bahasa Indonesia. 324 participants (246 from hospitals and 78 from primary healthcare facilities) were involved in this study. Understanding of the exact meaning of questions by study participants was improved by adding T2DM daily activity examples (e.g. diet, exercise and adherence to therapy) to several questions after the translations and adaptation procedure. The factor analysis showed correlation among the four factors ranging from 0.40 to 0.67. The order in the factor analysis was first interpersonal distress, followed by emotional burden, physician distress, and regimen distress. The internal consistency for the four domains ranged from 0.78 to 0.83. The DDS17 Bahasa Indonesia provides a valid and reliable scale for assessing distress of Indonesian T2DM outpatients. The use of this instrument in future research and clinical trials is recommended for the Indonesian context.
