Psychometric evaluation of the Farsi version of the diabetes foot self-care bahavior scale

Validity and reliability of the English version of the Diabetic Foot Self-Care Questionnaire: a cross-cultural adaptation

Introduction

The objective of this study was to carry out the cross-cultural adaptation and validation of the Diabetic Foot Self-Care Questionnaire into the English language, broadening the applicability of this patient-reported outcome measure and improving the monitoring of patients with diabetic foot disease.

Methods

The validation study into English was conducted in two phases: cross-cultural adaptation and psychometric validation study. Short Form-12 Version 2, EuroQoL-5D and Foot Function Index were used to analyze the criterion validity. Item response, internal consistency, standard error of measurement, minimal detectable change and construct validity were calculated in the validation phase.

Results

An English version of the questionnaire (DFSQ-UMA-En) was successfully obtained. A total of n = 193 participants were tested to confirm the validity and reliability of the questionnaire. Internal consistency values ranged from very good to excellent (Cronbach's α =0.889-0.981), and reliability was excellent (ICC = 0.854-0.959). Standard error measurement value was =2.543. Criterion validity ranged from r = 0.429 to r = 0.844. For construct validity, Kaiser-Meyer-Olkin test was =0.752.

Conclusion

DFSQ-UMA-En is a valid and reliable tool with good readability and comprehension features. This questionnaire addresses foot self-care behaviors in patients with diabetic foot disease, standing out as essential for early diagnosis and prevention strategies in clinical and research settings.

Psychometric properties of the Farsi version of diabetes burnout scale in patients with type 1 diabetes

OBJECTIVE

Diabetes burnout refers to the feeling of exhaustion and frustration in the management of diabetes, which can lead to treatment non-adherence, poor glycemic control, and a high prevalence of diabetes complications. Measuring diabetes burnout requires accurate and standard instruments. The aim of this study was to evaluate the psychometric properties of the Farsi version Diabetes Burnout Scale (F-DBS).

METHODS

This cross-sectional study was performed on 550 patients with type 1 diabetes (262 men and 288 women) referred to diabetes centers in different cities of Hamedan province (Asadabad, Hamedan, Malayer, and Nahavand) in 2021. The mean age and duration of the disease in these patients were 35.58 (SD=14.32) and 15.02 (SD=10.60) years, respectively. Data were collected using the Diabetes Burnout Scale (DBS), Patient Health Questionnaire-9 and Kessler psychological distress scale. After forward-backward translation, face, content and convergent validity were performed. To evaluate the construct validity, convergent validity, exploratory and confirmatory factor analysis were performed. Internal consistency was examined with Cronbach's alpha coefficients.

RESULTS

In the exploratory factor analysis, two factors of exhaustion (five items) and detachment (seven items) were extracted, which together explained 46.58% of the total variance. In confirmatory factor analysis, the fit indices were appropriate. There was a significant positive correlation between diabetes burnout and depression (r = 0.30, p < 0.001) and psychological distress (r = 0.36, p < 0.001). Cronbach's alpha coefficient of diabetes burnout, exhaustion and detachment were 0.813, 0.846 and 0.812, respectively.

CONCLUSION

The Farsi version of the Diabetes Burnout scale has acceptable validity and reliability and can be used in various studies.

Psychometric evaluation of the Persian version of the diabetic foot self-care questionnaire in Iranian patients with diabetes

BACKGROUND

Diabetic foot self-care refers to a group of self-management behaviors that can reduce the incidence of foot ulcers and amputations. It is necessary to have a valid and reliable standard tool to measure foot self-care in diabetic patients. This study aimed to evaluate the psychometric properties of the Persian version of the Diabetic Foot Self-Care Questionnaire of the University of Malaga, Spain (DFSQ-UMA) in Iran.

METHODS

This cross-sectional study was conducted with 407 diabetic patients who were selected using a convenient sampling method. Construct validity was assessed by exploratory (with 207 patients) and confirmatory (with 200 patients) factor analyses. Internal consistency was calculated using Cronbach's alpha and McDonald's omega coefficients.

RESULTS

In the exploratory factor analysis, three factors with eigenvalues of 3.84, 2.41, and 2.26 were extracted that together explained 56.74% of the total variance of diabetic foot self-care. A Cronbach's alpha of 0.865 was found for the total instrument.

CONCLUSIONS

The Persian version of the DFSQ-UMA has good validity and reliability, and given its good psychometric properties, it can be used in future studies.
