Psychometric Properties of Diabetes Management Self-Efficacy in Thai Type 2 Diabetes Mellitus Patients: A Multicenter Study

Influencing factors of care dependence in patients with coronary heart disease after percutaneous coronary intervention-A cross-sectional study

AIM

Care dependence has been scarcely investigated in coronary heart disease patients after percutaneous coronary intervention. This study aimed to investigate the association between frailty, self-efficacy, combined effects of frailty and self-efficacy, mental health, and care dependence in coronary heart disease patients after percutaneous coronary intervention.

DESIGN

Cross-sectional study.

METHODS

Data from 400 patients after percutaneous coronary intervention were collected from 2017-2020. Logistic regression model and mediating analysis were used to identify the association between frailty, self-efficacy, combined effects of frailty and self-efficacy, and care dependence.

RESULTS

Patients with frailty and self-efficacy tended to have severe care dependence symptoms. There was no correlation between frailty symptoms, self-efficacy, and care dependence in patients without symptoms of anxiety or depression. But in patients with anxiety or depression symptoms, there is a strong correlation between frailty symptoms, lower self-efficacy, and care dependence. Mental health played an inhibitory effect on frailty and care dependence.

Validity and reliability of the Arabic version of the Self-Efficacy for Managing Chronic Disease scale in rheumatoid arthritis patients

BACKGROUND AND OBJECTIVES

Rheumatoid arthritis (RA) is an autoimmune inflammatory condition that causing disability and affection of patient's quality of life (QoL). Self-efficacy investigation helps us to detect the requirements of chronically affected patients and evaluation of self-care management programs. The aim of our study was to test validity and reliability of Self-Efficacy for Managing Chronic Disease (SEMCD-Arabic) in RA patients.

METHOD

This study included 248 RA patients, carried out at Rheumatology and Rehabilitation Department. The SEMCD-Arabic Validity was assessed by correlating the SEMCD-Arabic scale with the validated Arabic version of the modified Health Assessment Questionnaire HAQ (MHAQ), the Arabic version of the Multidimensional Assessment of Fatigue (MAF) scale, and the Arabic version of Short Form 36 version 2 for quality of life (SF QoL). Internal consistency, test-retest reliability was assessed.

RESULTS

Convergent validity was confirmed by a positive correlation between (physical, mental) component of SF QoL and SEMCD-Arabic (r = 0.918, r = 0.925) respectively, and negative correlation between MAF and SEMCD-Arabic (r =  - 0.657) and MHAQ with SEMCD-Arabic (r =  - 0.595). Discriminant validity confirmed by a significant negative correlation between visual analogue scale (VAS) for pain, disease activity scale (DAS28), Morning stiffness, patient health, physician health, age, duration, and SEMCD-Arabic (r =  - 0.1-0.7) (P < 0.001). Test-retest reliability was estimated which revealed a high interclass correlation coefficient (ICC = 0.87-0.997) indicating excellent agreement and internal consistency is acceptable as the Cronbach's alpha value (0.660 to 0.78).

CONCLUSION

The SEMCD-Arabic questionnaire can be used as a valid and reliable measure for assessment of patient's self-efficacy in RA. Key Points • The SEMCD-Arabic questionnaire has a statistically significant validity in correlation with different clinical manifestations MHAQ, SF QoL, and MAF. • The Arabic SEMCD is highly reliable with a Cronbach's alpha of 0.660 to 0.78.

Psychometric properties of the general self-efficacy scale among Thais with type 2 diabetes: a multicenter study

Background

Type 2 diabetes (T2D) is one of the most common chronic diseases in the world. In recent decades the prevalence of this disease has increased alarmingly in lower to middle income countries, where their resource-limited health care systems have struggled to meet this increased burden. Improving patient self-care by improving diabetes knowledge and diabetes management self-efficacy represents a feasible way of ameliorating the impact of T2D on the patient, and the health care system. Unfortunately, the relationships between self-efficacy, diabetes self-management, and thereafter, patient outcomes, are still far from well understood. Although a domain-specific measure of diabetes management self-efficacy, the Diabetes Management Self-Efficacy Scale (DMSES), has been validated in the Thai T2D population, more general measures of self-efficacy, such as the General Self-Efficacy scale (GSE) have not been validated in this population. In this paper we translate and examine the psychometric properties of the GSE in Thais living with T2D.

Methods

In this nation-wide study we examined the psychometric properties of the GSE in 749 Thais diagnosed with T2D within the last five years, and evaluated its relationship with the DMSES along with other patient characteristics. Reliability of GSE was assessed using Cronbach's alpha, and the construct validity was examined using confirmatory factor analysis, along with GSE's convergence and discrimination from DMSES.

Results

The Thai version of the GSE was shown to have good psychometric properties in Thais living with T2D. Cronbach's alpha was shown to be 0.87 (95% CI [0.86, 0.88]). We also demonstrated the structural validity of the GSE (Tucker-Lewis Index = 0.994, Cumulative Fit Index = 0.995, Adjusted Goodness of Fit Index = 0.998, Root Mean Square Error of Approximations = 0.025, 95% CI [0.06-0.039]), and that this instrument has a similar structure in Thais as in other populations. GSE was also shown to have some overlap with the DMSES with correlations among GSE and the DMSES domains ranging from 0.18 to 0.26, but also the GSE has substantial discrimination from DMSES (Disattenuated correlation coefficient = 0.283, 95% CI [0.214-0.352], p < 0.001). This suggests that while general and diabetes management self-efficacy are somewhat associated, there are aspects of diabetes management self-efficacy not captured by the more stable general self-efficacy.

Conclusions

We demonstrate that the Thai GSE is a reliable and valid measure. We believe the GSE may represent a useful tool to examine the efficacy of proposed and existing diabetes self-management, and management self-efficacy interventions.

Translation and psychometric validation of the Arabic Gestational Diabetes Management Self-Efficacy Scale (GDMSES)

INTRODUCTION

The assessment of self-efficacy for adherence to healthy behaviours among women with gestational diabetes (GDM) is undermined by the unavailability of validated tools. Therefore, this study aimed at translating, culturally adapting and assessing the psychometric properties of the Arabic version of Gestational Diabetes Management Self-Efficacy Scale (GDMSES).

MATERIALS AND METHODS

This methodological study was conducted in the Antenatal Clinic at Sultan Qaboos University Hospital in Oman between October 2016 and January 2017. A total of 90 forms of the Arabic GDMSES tool were completed by Omani pregnant women with gestational diabetes. The study has a multiphase design: (1) cultural and linguistic validation; (2) content and face validity; (3) construct validity; (4) internal validity.

RESULTS

The Arabic GDMSES showed satisfactory content validity (CVI between .8 and 1), acceptable overall scale internal consistency reliability (Cronbach's alpha=0.85) and stability overtime (Pearson correlation coefficient>.6). Four factors emerged for construct validity using exploratory factor analysis: nutrition and body weight, adaptation to healthy eating, physical activity and treatment and blood sugar. Our sample size of 90 was considered adequate in determining these factors (Kaiser-Meyer-Olkin=.78).

CONCLUSIONS

GDMSES is a valid and reliable tool, thus providing a quick and easy self-efficacy assessment tool for antenatal nurses dealing with pregnant women with GDM.

Development and evaluation of self-care intervention to improve self-care practices among people living with type 2 diabetes mellitus: a mixed-methods study protocol

INTRODUCTION

The management of diabetes mellitus (DM) depends on medication adherence, self-care and regular follow-up to prevent complications and premature mortality. This study aims to develop and implement the behavioural change theory and model based diabetes self-care intervention package to improve self-care practices among people living with type 2 DM.

METHODS AND ANALYSIS

An exploratory sequential mixed-method study design wherein, quantitative follows qualitative will be used to develop, implement and evaluate the effect of diabetes self-care intervention package among people living with type 2 diabetes. The qualitative research method will be used to identify barriers and facilitators for self-care practices among people living with type 2 DM and will also provide the basis for the development of the diabetes self-care intervention package. The quasi-experimental with control study design will be used to evaluate the developed intervention package among 220 randomly selected people living with type 2 diabetes in both intervention and control arms. Baseline, follow-ups and endline data will be collected using same prevalidated and structured questionnaire for each self-care activity. Difference-in-difference analysis will be used to measure for changes in the proportion of people living with type 2 DM doing different component of self-care practices, preintervention and postintervention in both arms.

ETHICS AND DISSEMINATION

Permission for conducting the study has been taken from Institutional Ethical Committee of PGIMER, Chandigarh (Ref no. NK/4538/PhD/226, Dated 18.08.18). The findings of the trial will be disseminated through publication in peer-reviewed journals.

Impact of diabetes self-management, diabetes management self-efficacy and diabetes knowledge on glycemic control in people with Type 2 Diabetes (T2D): A multi-center study in Thailand

We investigate the relationship of diabetes knowledge, diabetes management self-efficacy and diabetes self-management with blood glucose control among people with Thai type 2 diabetes mellitus (T2D). Seven hundred outpatients from diabetes clinics from large university and small community hospitals in two provinces of Thailand (Khon Kaen and Bangkok) were interviewed to evaluate their diabetes knowledge (DK), diabetes management self-efficacy (DMSE) and diabetes self-management (DSM). In addition, patient medical records were accessed to obtain other patient characteristics including patients’ HbA1c levels. Bivariate and multivariable logistic regression modelling was conducted and unadjusted and adjusted odds ratios obtained, respectively. Over half (52.4%) of the patients in our sample failed to control their blood glucose (HbA1c > 7%). All three psychometric measures (DK, DMSE and DSM) were identified as associated with blood glucose control in the bivariate analysis (OR_DK(unadj) = 0.89, 95%CI: 0.82, 0.96; OR_DSM(unadj) = 1.64, 95%CI: 1.46, 1.82; OR_DMSE(unadj) = 2.84; 95%CI: 2.43, 3.32). However, after mutual adjustment and adjustment for other patient characteristics, of the three psychometric measures, only diabetes management self-efficacy remained associated with blood glucose control (OR_DMSE(adj) = 2.67; 95%CI: 2.20, 3.25). Diabetes management self-efficacy is shown to be strongly associated with blood glucose control in the Thai Type 2 diabetes population. Current early diabetes interventions in Thailand tend to focus on disease knowledge. A stronger emphasis on enhancing patients’ disease management self-efficacy in these interventions is likely to lead to substantial improvement in both diabetes self-management and blood glucose control, thereafter reducing the risk, or prolonging the development, of chronic diabetes complications.

Scalable solution for delivery of diabetes self-management education in Thailand (DSME-T): a cluster randomised trial study protocol

INTRODUCTION

Type 2 diabetes mellitus is among the foremost health challenges facing policy makers in Thailand as its prevalence has more than tripled over the last two decades, accounting for considerable death, disability and healthcare expenditure. Diabetes self-management education (DSME) programmes show promise in improving diabetes outcomes, but this is not routinely used in Thailand. This study aims to test a culturally tailored DSME model in Thailand, using a three-arm cluster randomised controlled trial comparing a nurse-led model, a peer-assisted model and standard care. We will test which model is effective and cost effective to improve cardiovascular risk and control of blood glucose among people with diabetes.

METHODS AND ANALYSIS

21 primary care units in northern Thailand will be randomised to one of three interventions, enrolling a total of 693 patients. The primary care units will be randomised (1:1:1) to participate in a culturally-tailored DSME intervention for 12 months. The three-arm trial design will compare effectiveness of nurse-led, peer-assisted (Thai village health volunteers) and standard care. The primary trial outcomes are changes in haemoglobin A1c and cardiovascular risk score. A process evaluation and cost effectiveness evaluation will be conducted to produce policy relevant guidance for the Thai Ministry of Public Health. The planned trial period will start in January 2020 and finish October 2021.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from Thailand and the UK. We will share our study data with other researchers, advertising via our publications and web presence. In particular, we are committed to sharing our findings and data with academic audiences in Thailand and other low-income and middle-income countries.

Cross-Cultural Reliability of an Arabic Version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale in Arab Patients with Diabetes mellitus

INTRODUCTION

Arab nations have the second highest diabetes mellitus (DM) prevalence in the world. There is a growing interest in self-management programs that emphasize patient's central role in managing type 2 DM.

AIM OF THE STUDY

To validate an Arabic version of the Self-Efficacy for Managing Chronic Disease 6-Item Scale (SEM6S) among Arab type 2 DM patients and to explore factors associated with self-efficacy measured with the SEM6S.

METHODS

Cross-sectional study on 302 Arab patients with T2DM of three different nationalities (Egyptian, Saudi, Kuwaiti).The SEM6S was translated using forward-backward method, and its reliability was determined by calculating Cronbach's alpha. A regression model was used to examine variables associated with self-efficacy in Arab patients with T2DM.

RESULTS

Questionnaire was successfully translated without language or content-related problem. The mean age of participants was 47.71±14.7 years with equally represented sexes. The mean total score of the SEM6S was 5.99±1.86. The scale psychometric properties was reproducible (ICC=0.61-0.71) with good reliability (Cronbach's alpha=0.79). Statistically significant increase in self-efficacy was observed in patients <30 years, uncomplicated DM, DM with hypertension, and in patients who had physical activity > 60min per day. Also, a bimodal increase in self-efficacy was detected in patients with DM<5 years and 10.1-15 years. After regression analysis, physical activity was significantly positively correlated with self-efficacy (β=0.8, P=0.01), and duration of diabetes was significantly negatively correlated with self-efficacy (β = -0.23, P=0.03).

CONCLUSION

Arabic SEM6S is acceptable, reliable and repeatable metric for self-efficacy.

Correlations among Psychological Resilience, Self-Efficacy, and Negative Emotion in Acute Myocardial Infarction Patients after Percutaneous Coronary Intervention

OBJECTIVE

We investigated the influencing factors of the psychological resilience and self-efficacy of acute myocardial infarction (AMI) patients after percutaneous coronary intervention (PCI) and the relationships of psychological resilience and self-efficacy with negative emotion.

METHODS

Eighty-eight participants were enrolled. Psychological resilience, self-efficacy, and negative emotion were assessed with the Psychological Resilience Scale, Self-Efficacy Scale, Zung Self-Rating Anxiety Scale (SAS), and Zung Self-Rating Depression Scale (SDS), respectively. Furthermore, the relationships of psychological resilience and self-efficacy with negative emotion were investigated.

RESULTS

The average scores of psychological resilience, self-efficacy, anxiety, and depression were 70.08 ± 13.26, 21.56 ± 9.66, 53.68 ± 13.10, and 56.12 ± 12.37, respectively. The incidences of anxiety and depression were 23.90% (21/88) and 28.40% (25/88), respectively. The psychological resilience and self-efficacy scores of AMI patients after PCI varied significantly with age and economic status. SAS scores and SDS scores were significantly negatively correlated with psychological resilience and self-efficacy.

CONCLUSION

Negative emotions in AMI patients after PCI are closely related to psychological resilience and self-efficacy. Therefore, anxiety and depression could be alleviated by improving the psychological resilience and self-efficacy of patients undergoing PCI, thus improving patients' quality of life.
