Reliability and Validity of Mongolian Version of Diabetes Quality of Life Brief Clinical Inventory for Type II Diabetes

Abstract

Background: Diabetes mellitus (DM) is a global health challenge affecting patient well-being and quality of life (QoL). This study aimed to validate the Mongolian version of the Diabetes Quality of Life Brief Clinical Inventory (MVD-QOL-BCI) in patients with type II DM in Mongolia. Methods: Data were collected from 197 participants across three hospitals in Ulaanbaatar. Reliability was assessed using Cronbachʼs alpha and the intraclass correlation coefficient (ICC). Pearsonʼs correlation was used for criterion-related validity and discriminant validity were examined using demographic, disease-specific, and general QoL questionnaires. Results:The MVDQOL-BCI demonstrated strong internal consistency (α＝0.853) and satisfactory test-retest reliability (ICC＝0.842). Criterion-related validity was confirmed with the Asian DQOL total score, EQ-visual analog scale score, short-form 36 total scores, 8 subscales, and HbA1c percentage (p＜0.05). Discriminant validity revealed better QoL was associated with females, higher education, higher income, shorter diabetes duration, and non-insulin therapy use. Conclusions:The MVDQOL-BCI is a reliable and valid tool for assessing QoL in adult Mongolian patients with DM. Our findings support the extensive utilization of the MVDQOL-BCI and facilitates a deeper understanding of the impact of diabetes and its management on patient well-being.
