Abstract

Diabetes Distress (DD)—an emotional or affective state arise from challenge of living with diabetes and the burden of self-care—negatively impact diabetes management and quality of life of T2DM patients. Early detection and management of DD is key to efficient T2DM management. The study aimed at developing a valid and reliable instrument for Bangladeshi patients as unavailability such a tool posing challenge in diabetes care. Linguistically adapted, widely used, 17-item Diabetes Distress Scale (DDS), developed through forward–backward translation from English to Bengali, was administered on 1184 T2DM patients, from four diabetes hospitals in Bangladesh. Psychometric assessment of the instrument included, construct validity using principal component factor analysis, internal consistency using Cronbach’s α and discriminative validity through independent t-test and test–retest reliability using intraclass-correlation coefficient (ICC) and Kappa statistics. Factor analysis extracted 4 components similar to original DDS domains, confirms the construct validity. The scale demonstrated satisfactory internal consistency (α = 0.838), stability (test–retest ICC = 0.941) and good agreement across repeated measurements (Kappa = 0.584). Discriminative validity revealed that patients with complication (p < 0.001) and those are on insulin (p < 0.001) had significantly higher distress scores in all domains. Bengali version of DDS is a valid and reliable tool for assessing distress among Bangladeshi T2DM patients.

Highlights

Their implementation[18,19]
Periodic assessment of DD should be enshrined in the management protocols of DM13,17
Generic tools can be used for diagnosing type 2 DM (T2DM) related distress, a Diabetes mellitus (DM)-specific and psychometrically validated instrument may increase the precision of detection and help in choice of most appropriate intervention thereof

Summary

Introduction

Their implementation[18,19]. periodic assessment of DD should be enshrined in the management protocols of DM13,17. There are a handful of instruments available for assessing diabetes distress[20,21,22,23,24], of which the Diabetes Distress Scale (DDS) is considered most efficient among the most widely used globally[24]. Generic tools can be used for diagnosing T2DM related distress, a DM-specific and psychometrically validated instrument may increase the precision of detection and help in choice of most appropriate intervention thereof. The primary goal of the study is to develop a linguistically validated DD detection tool for Bangladeshi patient population which can be used clinical and research setting. The current study, aimed to translate the DDS-17 in Bengali and to perform psychometric validation in Bangladeshi T2DM patient population
