Validation of the Amharic version of the summary of diabetes self-care activity scale among type 2 diabetes patients in Addis Ababa, Ethiopia, 2023

Abstract

Introduction: Measuring what it tends to measure makes a tool powerful and useful for decision-making. As the Amharic version summary of the diabetes self-care activity scale construct hasn't yet been validated, there is an urgent need for validation. This study aims to validate the Amharic version of the summary of the diabetes self-care activity scale among type 2 diabetes mellitus patients in Addis Ababa hospitals. Methods: A facility-based cross-sectional study design was used to recruit 600 participants. The data was collected using open-data-kit and exported to SPSS and STATA for analysis. Both exploratory and confirmatory factor analysis was performed on 300 randomly allocated separate samples. Result: A total of four factors with an eigenvalue greater than one, constituting nine items, were identified. The average variance executed (AVE) becomes 0.78, with a composite reliability of 0.97. Hence there is convergence between the items and the new construct. The overall internal consistency of the new construct was 0.853, which is greater than 0.7, affirming the reliability of the construct. Conclusion: We can conclude that this 4-factor structure with a 9-item Amharic version of SDSCA is highly valid and reliable. Researchers and clinicians are highly recommended to use this validated tool.
