Validation of the Greek Version of the Diabetes Management Self-Efficacy Scale (GR-DMSES).

ABSTRACT:

Introduction

Self-efficacy has been found to have a direct relation with self-care in diabetes. Several tools have been developed and used for evaluating self-efficacy of diabetic patients, the most widely used being the Diabetes Management Self-Efficacy Scale (DMSES). The aim of the present study was to translate, culturally adapt, and validate the Greek DMSES (GR-DMSES) in order for it to be used in the ATTICA pilot study of the SmartCare EU-funded project.

Methods

Using standard procedures, the original version of DMSES was translated and culturally adapted into Greek. Content validity was assessed by an expert panel with the calculation of a content validity index of the overall scale. Α convenient sample was recruited to complete the questionnaire. Psychometric testing of the produced instrument included internal consistency test (Cronbach's alpha), construct validity (factor analysis), and stability (intraclass correlation coefficient).

Results

One hundred and sixteen patients, aged 36-86 years, with type 2 diabetes (T2D) participated in the study. There were no items excluded from the original scale after the content validity procedure. The coefficient Cronbach's alpha for the internal consistency was 0.93 and the intraclass correlation coefficient for the stability with a 5-week time interval was 0.87 (P < 0.001). Factor analysis yielded four factors related to diet, medical therapy, medication and feet check, and physical activity.

Conclusion

The findings supported that the GR-DMSES was reliable and valid in measuring self-efficacy related to diabetes self-management, thus providing a quick and easy-to-use tool for health professionals dealing with Greek adults with T2D.

Project description:Being highly self-efficacious is a key factor in successful chronic disease self-management. In the context of measuring self-efficacy in type 2 diabetes management, the Diabetes Management Self-Efficacy Scale (DMSES) is the most widely used scale. The aim of this study was to adapt the English version of the scale to Italian and to evaluate the psychometric properties of the Italian version of DMSES in type 2 diabetes (IT-DMSES).We conducted a cross-sectional study of people with type 2 diabetes attending the Endocrine-Metabolic Disease Care Unit of the Internal Medicine Department of San Marino State Hospital between October 2016 and February 2017. Patients completed a socio-demographic and clinical data form, the IT-DMSES and 3 self-report questionnaires measuring diabetes distress (PAID-5), psychological well-being (WHO-5) and depression (PHQ-9). Psychometric testing included construct validity (principal component analysis), internal consistency (Cronbach's ? coefficient) and convergent/discriminant validity (Spearman's correlation coefficient). Decision tree analysis was performed to classify patients into homogeneous subgroups of self-efficacy based on their demographic and clinical characteristics.Participants were 110 males and 55 females, mean age of 65.2 years (SD?±?9), 56.9% had been diagnosed for 1-15 years, 63% had HbA1c level?>?53 mmol/mol. Two main factors underlain the construct of self-efficacy in diabetes management: 'Disease Management' and "Lifestyles Management". Disease Management had a good reliability (??=?.849) and Lifestyle Management had an excellent reliability (??=?.902) indicating that the instrument is internally consistent. A negative and weak correlation was found between Lifestyle management, PAID-5 (r?=?-?0.258, p?=?<?0.01) and PHQ-9 (r?=?-?0.274, p?=?<?0.01) and a positive one with WHO-5 (r?=?0.325, p?<?0.01) supporting convergent validity. Disease management was uncorrelated with PAID-5 (r?=?-?0.142, p?=?0.083), PHQ-9 (r?=?-?0.145, p?=?0.076) and weekly correlated with WHO-5 (r?=?0.170, p?=?0.037) confirming discriminant validity. Higher levels of self-efficacy in lifestyle management were found in patients diagnosed for at least 1 year up to 15 years and aged >?65 years and the poorest self-efficacy was found in males <?65 years.Results support the validity and reliability of IT-DMSES. The scale can be used in research and clinical practice to monitor type 2 diabetes self-management over time.
