Psychometric properties of the Malay version of the Diabetes Empowerment Scale among Hospital Serdang type 2 diabetes mellitus patients using exploratory factor analysis

Abstract Background: Worldwide, type 2 diabetes mellitus (T2DM) is one of the most prevalent chronic diseases and one of those producing greatest impact on patients’ day-to-day quality of life. Our study aim is to validate the “Living with Chronic Illness Scale” for a Spanish-speaking T2DM population.Methods: In this observational, international, cross-sectional study, 582 persons with T2DM were recruited in primary care and outpatient hospital consultations, in Spain and Colombia, during the period from May 2018 to June 2019. The properties analysed were feasibility/acceptability, internal consistency, reliability, precision and (structural) content-construct validity including confirmatory factor analysis (CFA). The COSMIN checklist was used to assess the methodological/psychometric quality of the instrument.Results: The scale had an adequate internal consistency and test retest reliability (Cronbach’s alpha = 0.90; intraclass correlation coefficient = 0.96, respectively). In addition, the instrument is precise (standard error of measurement = 3.34, with values <½SD = 8.52) and correlates positively with social support (DUFSS) (rs = 0.56), quality of life (WHOQOL) (rs = 0.51-0.30) and satisfaction (SLS-6) (rs = 0.50-0.38). The original 26-items version of the scale did not support totally the CFA. The COSMIN checklist is favourable for all the properties analysed, although weaknesses are detected for structural validity.Conclusions: The LW-CI-T2DM is a valid, reliable and accurate instrument for use in clinical practice to determine how a person’s life is affected by the presence of diabetes. This instrument correlates well with the associated constructs of social support, quality of life and satisfaction. Additional research is needed to determine how well the questionnaire structure performs when robust factor analysis methods are applied.

Introduction: Type 2 diabetes mellitus is a non-communicating disease with an increasing trend in Malaysia. One of the most important aspects in the selfmanagement of diabetes mellitus is the assessment of knowledge among diabetes patients. This study aimed to translate and validate the Malay version of Modified Diabetes Knowledge Test (DKT) questionnaire. Methods: A standard back-to-back translation procedure was used to translate the simplified version of the DKT questionnaire from the original version. A total of 120 outpatients with type 2 diabetes mellitus from the government primary care clinic were selected to answer the questionnaire which consists of socio-demographic and diabetes characteristics questions as well as the 20-item DKT questions. Reliability and validity were tested with Cronbach’s alpha and Exploratory Factor Analysis. Results: The Cronbach’s alpha for the translated questionnaire was acceptable (α=0.573) with the Cronbach’s alpha excluding each item ranged from 0.517 to 0.602. Factor analysis with Varimax rotation identified 6 domains for the 18 items, with 2 to 6 items in each domain. Conclusion: This version of simplified DKT is proven to be valid and reliable, and can be used with caution as a brief assessment of knowledge among diabetic patients specifically tailored for Malaysian population.

The CFA supported the 5-domains structure, but a 23-item version showed better fit: CMIN/df= 3.11; goodness of fit index= 0.91; comparative fit index= 0.91 and root mean square error of approximation = 0.06 (90% confidence interval, 0.06-0.07). The COSMIN checklist is favourable for all the properties analysed, although weaknesses are detected for content validity.Conclusions: “Living with T2DM” (LW-T2DM) is a valid, reliable and accurate instrument for use in clinical practice to determine how a person’s life is affected by the presence of diabetes. This instrument correlates well with the associated constructs of social support, quality of life and satisfaction.
