Measuring Self-Care in Persons With Type 2 Diabetes: A Systematic Review

Validation of the Arabic version of the diabetes self-management questionnaire in patients with type 2 diabetes mellitus: a cross-sectional study

BACKGROUND

The number of instruments available for measuring diabetes self-management activities in Arabic countries has been limited to date. To our knowledge, no multidimensional instrument suitable for measuring diabetes self-management is currently available in Arabic. This study assessed the validation of the Arabic version of the Diabetes Self-Management Questionnaire (A-DSMQ) in patients with type 2 diabetes mellitus (T2DM).

METHODS

This cross-sectional study was conducted from May to August 2022 at primary healthcare centers within the Riyadh region of Saudi Arabia. Four steps were followed during the translation and adaptation of the DSMQ: forward translation, consulting an expert panel, backward translation, and pilot testing on the target population. The data were collected using a convenience sample of 154 patients with T2DM. Cronbach's α coefficient, criterion validity, and known-group validity were determined.

RESULTS

Cronbach's α coefficient for internal consistency was 0.76. The A-DMSQ "sum scale" scores were negatively correlated with glycosylated hemoglobin (HbA1c) levels (Pearson's r =  - 0.48, p < 0.01) and body mass indices (r =  - 0.29, p < 0.01) and positively correlated with Self-Rated Health Scale scores (r = 0.41, p < 0.01). Mean A-DSMQ "sum scale" scores differed significantly among groups with adequate, partially adequate, and inadequate glycemic control (F = 23.193, p < 0.001).

CONCLUSIONS

These results indicate that the A-DSMQ is a reliable and valid tool for measuring diabetes self-management in patients with T2DM. The A-DSMQ can be used by researchers and healthcare providers interested in assessing diabetes self-management in this population. Healthcare providers should remain alert for suboptimal diabetes self-management, which may lead to significant economic costs in emergency and healthcare utilization.

Validation of the Portuguese version of the diabetes self-management questionnaire-revised (DSMQ-R) in people with type 2 diabetes mellitus

BACKGROUND

Reflecting people with diabetes' self-management activities is often required in both research and clinical practice. This study evaluated the measurement properties of the Portuguese version of the Diabetes Self-Management Questionnaire-Revised (DSMQ-R) on a sample of people with type 2 diabetes mellitus (T2DM).

METHODS

Translation and cultural adaptation were conducted according to guidelines for cross-cultural adaptation and validation of healthcare measurement instruments. A cross-sectional study was performed including 365 people with T2DM in primary care. Reliability, construct validity, and criterion validity were analyzed.

RESULTS

The total scale of the translated DSMQ-R revealed sufficient internal consistency (alpha = 0.82), and most of the subscales performed adequately. The exploratory factor structure was robust, and confirmatory analysis showed a good model fit with the scale structure of the original scale. The scale scores correlated with the participants' last HbA1c estimates, supporting convergent validity, and convergence was confirmed by the adequate average variance extracted.

CONCLUSIONS

The Portuguese version of the DSMQ-R is a reliable and valid tool for gauging self-management behaviors in people with T2DM and their relationship with glycemic values.

A cross-sectional study on diabetes self-management practice and its association with glycemic control among type 2 Diabetes patients

Context

Diabetes has emerged as a major chronic public health problem throughout the world. Self-management by diabetes patients is very important for controlling blood sugar levels and preventing complications of diabetes.

Aims

The present study was conducted to study self-management practices among diabetes patients and to analyse socio-demographic factors associated with them.

Methods and Materials

A cross-sectional analytical study was conducted among 230 randomly selected diabetes patients in the Andaman and Nicobar Islands. The self-management practices were measured by the diabetes self-management questionnaire (DSMQ).

Statistical Analysis Used

The association of the DSMQ score with socio-demographic factors and blood sugar level was analysed by statistical tests like the T-test, analysis of variance (ANOVA) test, Tukey's honestly significant difference, and Chi-square test.

Results

The mean DSMQ score of the diabetes patients was 29.55 ± 5.98. There was a significant difference between the mean DSMQ score and the educational level (P value = 0.009), residential status (P value = 0.037), and duration of diabetes (P value = 0.006). The subcomponent analysis of the DSMQ score revealed that the glucose management score of rural people (9.38 ± 3.36) was significantly higher (P value = 0.006) than that of urban people (8.32 ± 2.46), and the diet control score was significantly higher (P value = 0.02) in patients with normal post-prandial blood sugar (PPBS) (7.64 ± 2.18) than in patients with raised PPBS (6.96 ± 2.12).

Conclusions

Higher educational level, rural background, and long duration of diabetes were associated with better self-management practices. The patients with normal blood sugar levels showed higher diet control scores than the patients with raised blood sugar levels.

Turkish Validity and Reliability of Comprehensive Diabetes Self-Management Scale

Objectives

A self-care approach is very important in diabetes management. In this study, it was aimed to make the Turkish validity and reliability of the Comprehensive Diabetes Self-Management Scale (CDSMS), which examines the behaviors of diabetes patients.

Methods

The study is of methodological type. CDSMS, which was translated into Turkish from its original version and tested for language validity, was first included in the pilot application and then in the main study. The validity of the scale was evaluated by the Cronbach's alpha coefficient. Then, a Receiver Operating Characteristic (ROC) analysis was performed to determine the cut off score.

Results

The mean age of the study participants was 57.10 ± 11.20 years and the mean disease duration was 9.96 ± 7.79 years. The internal consistency of CDSMS was 0.73, which was measured using Cronbach's alpha. After the ROC analysis, the optimal cut-point score of CDSMS to predict good glycemic control was determined as 21.17 points.

Conclusion

With this study, it was found that the Turkish version of CDSMS is valid and reliable for use in the Turkish population. It is thought that CDSMS will be beneficial to physicians working in the clinic in terms of showing the disease management skills of diabetic patients.

Instruments for measuring self-management and self-care in geriatric patients - a scoping review

Introduction

With demographic changes, prioritizing effective care for geriatric patients to maintain functionality, independence, and quality of life is crucial. Well-developed self-management or self-care abilities, which can be maintained and improved through interventions, are of the utmost importance. To implement these interventions tailored and effectively, a thorough assessment of the individual's self-management and self-care abilities is required.

Objective

This scoping review aimed to identify self-management and self-care instruments suitable for geriatric patients, their underlying theories and definitions of self-management and self-care, and their similarities and differences in item content.

Methods

A systematic search of the PubMed and CINAHL databases was conducted to identify retrievable full-text articles published in English in the medical and nursing fields since the 1970s, which were validated on a sample with an average age of at least 70 years, used generic rather than disease-specific items, and addressed the broad range of self-management and self-care abilities.

Results

Of the 20 included articles, six instruments were identified that were based on different theories and offered varying definitions of self-management or self-care. Despite these differences, all emphasize empowered individuals taking an active role in their care. Most address actual behavior and abilities referring to lifestyle factors and (anticipated) adjustment behavior. However, crucial aspects, such as psychological factors, (instrumental) activities of daily living, and social environment are not fully addressed in these instruments, nor are the types of execution to which the items refer, such as wants, feelings, confidence, or attitudes.

Conclusion

To fully understand how geriatric patients implement daily self-management or self-care, a combination of instruments covering the important factors of self-management and self-care and addressing multiple types of item execution, such as behaviors, abilities, wants, or attitudes, is recommended. This review provides the first comprehensive overview of self-management and self-care instruments suitable for geriatric patients.

Quality of measurement properties of medication adherence instruments in cardiovascular diseases and type 2 diabetes mellitus: a systematic review and meta-analysis

BACKGROUND

Medication adherence has a major impact on reducing mortality and healthcare costs related to the treatment of cardiovascular diseases and diabetes mellitus. Selecting the best patient-reported outcome measure (PROM) among the many available for this kind of patient is extremely important. This study aims to critically assess, compare and synthesize the quality of the measurement properties of patient-reported outcome measures to assess medication adherence among patients with cardiovascular diseases and/or type 2 diabetes mellitus.

METHODS

This review followed the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). The searches were performed in Web of Science, SCOPUS, PubMed, CINAHL, EMBASE, LILACS, PsycINFO, and ProQuest (gray literature).

RESULTS

A total of 110 records encompassing 27 different PROMs were included in the review. The included records were published between 1986 and 2023, most of which reported studies conducted in the United States and were published in English. None of the PROMs were classified in the category "a", thus being recommended for use due to the quality of its measurement properties. The PROMs that should not be recommended for use (category "c") are the MTA, GMAS, DMAS-7, MALMAS, ARMS-D, and 5-item questionnaire. The remaining PROMs, e.g., MMAS-8, SMAQ, MEDS, MNPS, ARMS-12, MGT, MTA-OA, MTA-Insulin, LMAS-14, MARS-5, A-14, ARMS-10, IADMAS, MAQ, MMAS-5, ProMAS, ARMS-7, 3-item questionnaire, AS, 12-item questionnaire, and Mascard were considered as having the potential to be recommended for use (category "b").

CONCLUSION

None of the included PROMs met the criteria for being classified as trusted and recommended for use for patients with cardiovascular diseases and/or type 2 diabetes mellitus. However, 21 PROMs have the potential to be recommended for use, but further studies are needed to ensure their quality based on the COSMIN guideline for systematic reviews of PROMs.

Instruments Measuring Self-Care and Self-Management of Chronic Conditions by Community-Dwelling Older Adults: A Scoping Review

Given the high prevalence of chronic conditions and multimorbidity in older adults, there is a need to better conceptualize and measure self-care and self-management to promote a person-centered approach. This scoping review aimed to identify and map instruments measuring self-care and self-management of chronic conditions by older adults. We searched six electronic databases, charted data from the studies and tools and reported the results in accordance with the PRISMA-ScR guidelines. A total of 107 articles (103 studies) containing 40 tools were included in the review. There was substantial variation in the tools in terms of their aims and scope, structure, theoretical foundations, how they were developed, and the settings in which they have been used. The quantity of tools demonstrates the importance of assessing self-care and self-management. Consideration of the purpose, scope, and theoretical foundation should guide decisions about tools suitable for use in research and clinical practice.

The relationship between self-care activities, social support, and glycemic control in primary healthcare patients with type 2 diabetes

Objective

Egyptian studies in assessing the relationship between diabetes self-care, social support, and glycemic control in primary healthcare (PHC) are limited. Therefore, this study aimed to assess this relationship, and to evaluate the associated factors of diabetes self-care, social support, and glycemic control in Egyptian PHC patients with type 2 diabetes (T2DM).

Methods

A cross-sectional study was conducted on 320 T2DM patients at four PHC settings in Port Said city, affiliated with the General Authority of Healthcare. A semi-structured questionnaire was used to collect data, including demographic characteristics, socioeconomic status scale, disease profile, the Arabic versions of the Summary of Diabetes Self-Care Activities, and the received social support scales. Data were collected from January 2020 to June 2020.

Results

Diabetes self-care activities, and self-monitoring of blood glucose had a very weak negative correlations with glycated hemoglobin (HbA1c) levels (rho = - 0.125, p = 0.025, rho = - 0.112, p = 0.044, respectively). Receiving social support on following a meal correlated positively and very weakly with HbA1c levels (rho = 0.145, p = 0.010). Hardly positive correlation was found between receiving emotional support on feelings about diabetes, and following a specific diet (rho = 0.169, p = 0.002). Diabetes self-care activities were positively associated with higher education levels, and elevated BMI. Received social support was negatively associated with having coronary artery disease, and marital status e.g. divorced and widow. Increased age, and female gender were the predictors of good glycemic control.

Conclusion

Diabetes self-care activities were linked with reduced HBA1c levels. Further studies are needed to evaluate the buffering effect of social support on glycemic outcomes in PHC patients with T2DM.

Diabetes self-management and its associated factors among patients with diabetes in central Vietnam: A cross-sectional study

Objective

Diabetes self-management (DSM) enables maintenance of optimal individualized glycemic control for patients with diabetes through comprehensive lifestyle, medication adherence, and self-monitoring glucose level. This study aimed to evaluate DSM and to find associated factors among Vietnamese diabetes patients by using the Vietnamese version of Diabetes Self-Management Instrument (DSMI).

Methods

A cross-sectional study was conducted at a single hospital in the central Vietnam. DSM was assessed using the DSMI. The participant’s socio-demographic and clinical features were obtained through face-to-face interviews and medical records. Multivariate linear regression was used to determine independent factors associated with total DSMI.

Results

The mean total DSM score based on DSMI self-administered questionnaire scores was 88.4 ± 22.1, with a range of 47 to 140. The mean self-integration, self-regulation, interaction with health professionals, self-monitoring blood glucose, and adherence to the prescribed regime were 24.8, 22.3, 21.6, 10.2, and 9.5, respectively. 48.1% of DM patients had good HbA1c control. Sex, educational status, BMI, waist circumference, medical nutrition therapy, and sufficient physical activities were factors independently predictive of DSMI total score.

Conclusion

This study emphasizes that the DSM situation is seen to be average among DM patients with mean DSMI score 88.4 ± 22.1 and sex, educational status, BMI, waist circumference, medical nutrition therapy, and sufficient physical activities were independently predictive factors of DSMI total score. This evidence suggests that there is a need to enhance the effectiveness of DSM education programs among diabetic patients.

Adaptation and Psychometric Evidence of the ARABIC Version of the Diabetes Self-Management Questionnaire (A-DSMQ)

(1) Background: Diabetic patients must engage in self-care practices in order to maintain optimal glycemic control, hence reducing the likelihood of developing complications, and enhance the overall quality of their lives. The Diabetes Self-care Management Questionnaire (DSMQ) is a tool for assessing self-management habits that may be used to predict glycemic control in people with diabetes. However, no Arabic language version of the instrument has been found. Therefore, we adapted an Arabic language version of the instrument in Tunisia. The purpose of the current research aimed to assess the psychometric features of the Tunisian version of the DSMQ in patients with type 2 diabetes. (2) Method: Two samples including both genders, one exploratory (n = 208, mean age 53.2 ± 8.3) and one confirmatory (n = 441, mean age 53.4 ± 7.4), completed an adapted Arabic language version of the DSMQ, a sociodemographic questionnaire and information about their HbA1C levels. (3) Results: The exploratory factor analysis revealed that the 15 items of the A-DSMQ fit well with the data. Likewise, the alpha coefficients for the A-DSMQ factors were above 0.80: for "Glucose Management" (GM), "Dietary Control" (DC), "Physical Activity" (PA), and "Heath-Care Use" (HU). The fit indices for the CFA were good, and the four-factor solution was confirmed. The Average Variance Extracted values and Fornell-Larcker criterion established the convergent and discriminant validity, respectively. The concurrent validity of the tool was established through the statistically significant negative relationships between the A-DSMQ factors and HbA1C, in addition to its positive association with the practice of physical activity measured by the IPAQ. (4) Conclusions: Given the high EFA factor loadings, the CFA fit indices, the correlation matrix, the sensitivity analysis, the convergent validity, and the excellent internal consistency of the A-DSMQ, it can be concluded that the A-DSMQ is an effective psychometric tool for diabetes self-management in Tunisia.

Assessing predictors of self-management intentions in people with type 2 diabetes

Background

Type 2 diabetes mellitus (T2D) is slowly turning into an international health emergency, evidenced by accelerated growth in prevalence rates worldwide. Experts have now called for greater integration of self-management interventions in clinical practice in light of these worrisome trends, supplanting the prevailing notion of a “glucocentric” approach. In this pilot study designed to complement a novel assessment program currently in development, we describe a concise screening tool designed to stratify the intention to follow through on self-management practices in people with T2D.

Methods

A cross-sectional survey was conducted at 3 regional primary care clinics. Individuals with T2D having the following characteristics were recruited into the study: (i) individuals with T2D between 18 and 65 years, (ii) fluent in English and, and iii) having been diagnosed with T2D for at least 2 years. We assessed the relevance of components in the Theory of Planned Behaviour (TPB) within the context of self-management behaviour in T2D. Participants were requested to complete a questionnaire containing questions related to intention, attitudes subjective norm and perceived behavioural control. Based on their responses, the psychometric properties of the scale were then evaluated using both reliability and validity analysis.

Results

The Cronbach α value for all direct measures of TPB was excellent: intention to adhere to self-management practices (0.98), attitude towards self-management behaviour (0.87), subjective norm (0.83), and perceived behaviour control (0.66). The correlation between intentions and all 3 constructs of TPB was excellent (p < 0.01). Structural equation modeling helped determine attitudes and subjective norms as important predictors of intentions to follow through self-management practices.

Conclusions

By first understanding the dimensions that influence intentions associated with self-management behaviour, clinicians have the opportunity to “triage” individuals with T2D who require greater involvement to bring about better self-care practices. Thus, our research attempts to bridge this gap by devising a psychometric tool suited to a regional setting which allows for an improved person-centered communication between clinicians and patients.

Development and evaluation of a new questionnaire to assess social cognitive factors of self-management in patients with type 2 diabetes: a psychometric study

Background

Self-care behaviors are essential to control blood sugar and to prevent mortality and complications of diabetes. The evidence suggests that social cognitive factors play a crucial role in adopting self-care behaviors. This study aimed to develop and examine the psychometric properties of the Diabetes Self-Management Questionnaire based on the social cognitive theory (DSMQ-SCT).

Methods

The present methodological cross-sectional study investigated 460 patients with T2DM referred to the Isfahan Endocrine and Metabolism Research Centre, Isfahan, Iran using the convenience sampling method. We assessed the reliability (internal consistency), content validity, convergent validity and construct validity. Construct validity was evaluated using exploratory factor analysis (calibration sample = 230) and confirmatory factor analysis (validation sample = 230).

Results

In the EFA with the varimax rotation, we extracted four factors that could explain 65.9% of the total variance of the DSMQ-SCT scale. The CFA exhibited a satisfactory fit level for the four-factor structure extracted from the EFA with the following measures. CFI: .971, IFI: .971, NFI: .942, TLI: .966, RMSEA: .046).Internal consistency was good (Cronbach's alpha coefficient for the whole scale: 0.88; the subscales: 0.85 to 0.92). The convergent validity showed significant negative correlations between DSMQ-SCT subscales and HbA1c.

Conclusion

DSMQ-SCT is a valid and reliable instrument to assess social cognitive factors associated with self-management behaviors in patients with T2DM. Therefore, this instrument can be used in both future research and clinical practices.

A Self-Report Measure of Diabetes Self-Management for Type 1 and Type 2 Diabetes: The Diabetes Self-Management Questionnaire-Revised (DSMQ-R) – Clinimetric Evidence From Five Studies

Aims

Measurement tools to evaluate self-management behavior are useful for diabetes research and clinical practice. The Diabetes Self-Management Questionnaire (DSMQ) was introduced in 2013 and has become a widely used tool. This article presents a revised and updated version, DSMQ-R, and evaluates its properties in assessing self-management practices in type 1 diabetes (T1D) and type 2 diabetes (T2D).

Methods

The DSMQ-R is a multidimensional questionnaire with 27 items regarding essential self-management practices for T1D and T2D (including diabetes-adjusted eating, glucose testing/monitoring, medication taking, physical activity and cooperation with the diabetes team). For the revised form, the original items were partially amended and the wording was updated; eleven items were newly added. The tool was applied as part of health-related surveys in five clinical studies (two cross-sectional, three prospective) including a total of 1,447 people with T1D and T2D. Using this data base, clinimetric properties were rigorously tested.

Results

The analyses showed high internal and retest reliability coefficients for the total scale and moderate to high coefficients for the subscales. Reliability coefficients for scales including the new items were consistently higher. Correlations with convergent criteria and related variables supported validity. Responsiveness was supported by significant short to medium term changes in prospective studies. Significant associations with glycemic outcomes were observed for DSMQ-R-assessed medication taking, glucose monitoring and eating behaviors.

Conclusions

The results support good clinimetric properties of the DSMQ-R. The tool can be useful for research and clinical practice and may facilitate the identification of improvable self-management practices in individuals.

Validation of the revised Diabetes Self-Management Questionnaire (DSMQ-R) in the primary care setting

Background

Available tools measuring self-management in diabetes are often improperly validated or do not correlate with glucose metabolism. The Diabetes Self-Management Questionnaire (DSMQ-R) is a valid tool, that showed strong relationship with glucose metabolism in tertiary care among people with mostly type 1 diabetes.

Aim of the study

To validate the translated DSMQ-R questionnaire in a Hungarian sample of people with predominantly type 2 diabetes in primary care.

Methods

We enrolled 492 adults from 38 practices in this cross-sectional cohort study, who filled out the self-administered questionnaire, consisting of DSMQ-R and the Summary of Diabetes Self-Care Activities (SDSCA) questionnaires. Family doctors provided clinical data. The translation process was performed in six steps, reaching the expert committee appraisal. The validity of the questionnaire was evaluated by assessing reliability and construct validity.

Results

Cronbach’s alpha showed the questionnaire to reach good reliability (α = 0.845), although subscales had lower alphas. Contrary to the SDSCA questionnaire, the DSMQ-R sum scale differed significantly between persons on target vs not on target (median (interquartile range): 7.23 (6.17–8.44) vs 6.91 (5.91–8.02), and the DSMQ-R sum scale correlated significantly with BMI, HbA1c and SDSCA sum scale. In multivariate analysis higher DSMQ-R scores were significant predictor of achieving glycemic target goal.

Conclusion

The Hungarian translation of the DSMQ-R is a comprehensible tool to assess self-management of persons with diabetes. The questionnaire is valid and reliable in family practice, although its association with achievement of diabetes HbA1c target is weaker in primary than in tertiary care.

Association analysis of SOCS3, JAK2 and STAT3 gene polymorphisms and genetic susceptibility to type 2 diabetes mellitus in Chinese population

AIM

The association of polymorphisms in the three genes of SOCS3, JAK2 and STAT3 with genetic susceptibility to type 2 diabetes mellitus (T2DM) was explored, and its interaction with environmental factors such as hypertension and triglycerides was analyzed.

METHODS

The Hardy-Weinberg balance test was used to analyze the random balance of genes in the population. The analysis of the association of SNPs with T2DM was performed using Pearson's chi-square test. Haplotype frequency distribution, SNPs-SNPs interaction and environmental factors were analyzed by chi-square test and logistic regression.

RESULTS

The genotype distribution of SNPs rs2280148 of the SOCS3 gene was statistically significant. The allele frequency distribution of SNPs (rs4969168/rs2280148) was statistically different. After covariate correction, the SOCS3 gene locus (rs4969168) showed an association with T2DM in additive model, while the rs2280148 locus showed an association with T2DM in all three models. The locus (rs10974914/rs10815157) allele and genotype frequency distribution of JAK2 were statistically significant. After covariate correction, two SNPs in the gene showed association with T2DM in both additive and recessive models. The distribution of genotype frequencies of SNPs rs1053005 locus in gene STAT3 was statistically significant between the two groups. In recessive genetic models, rs1053005 locus polymorphisms was associated with T2DM. Haplotype S3 (G G)/S 4 (G T) of the SOCS3 gene as well as haplotype J2 (A G)/J 3 (G C) of the JAK2 gene were closely associated with T2DM. There was an interaction between SNPs rs4969168 and SNPs rs2280148 in the SOCS3 gene. There was an interaction between the SOCS3, JAK2 and STAT3 genes and hypertension/triglycerides.

CONCLUSION

The SOCS3 and JAK2 genes may be associated with T2DM in the Chinese population, in which SNPs carrying the A allele (rs4969168)/G allele (rs2280148)/C allele (rs10815157) have a reduced risk of T2DM. Haplotype S3 (G G)/S 4 (G T) of the SOCS3 gene and haplotype J2 (A G)/J 3 (G C) of the JAK2 gene may be influencing factor for T2DM. The interaction between SNPs rs4969168 and SNPs rs2280148 increases the risk of T2DM. Hypertension and triglycerides may interact with SNPs of T2DM susceptibility genes.

Behavior change interventions in patients with type 2 diabetes: a systematic review of the effects on self-management and A1c

PURPOSE

This study aimed to identify the characteristics of interventions employed to promote behavior change in people with type 2 diabetes mellitus (T2DM) and their impact on disease self-management and glycated hemoglobin (A1c).

METHODS

The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used to guide the protocol development for this systematic review. Randomized controlled clinical trials which compared behavior change interventions to controls in adults with T2DM and investigated disease self-management and glycated hemoglobin (A1c) measured by validated methods were eligible for this study. The risk of bias and quality of evidence was assessed respectively by Cochrane's tool and grading of recommendations, assessment, development, and evaluation (GRADE).

RESULTS

A total of 27 studies were included involving 4464 participants. Behavior change was mainly promoted by education sessions on diabetes care delivered face-to-face, monthly, or every other month, lasting more than 60 min, involving blood glucose monitoring, healthy eating, exercise, and medication. Four studies showed significant improvement in both disease self-management and A1c. The risk of bias was classified as high in most studies. A meta-analysis could not be performed for A1c and self-management due to the high differences in intervention parameters (delivery mode, number, duration, and frequency) and self-management assessments.

CONCLUSION

Low evidence of improvement in disease self-management and A1c considering only validated assessment methods were found for behavior change interventions, mainly promoted by education sessions on diabetes care. The quality of studies and probably the differences in intervention protocols contributed to this finding.

Assessment of diabetes self-management amongst Nigerians using the diabetes self-management questionnaire: a cross-sectional study

INTRODUCTION

self-management is probably the most important factor contributing to achieving euglycaemia. The Diabetes Self-Management Questionnaire (DSMQ) is an instrument that shows favourable prospects compared to older measures. This study aimed to investigate the association between self-management and glycaemic control using the DSMQ, and determine factors that affect glycaemic control in patients living with diabetes mellitus.

METHODS

a cross-sectional analytic study of 103 patients, carried out in a public tertiary health institution located in a Southern Nigerian City. An interviewer administered DSMQ was used to assess self-management among the patients. Data analysis was performed using SPSS 22.0.0, and AMOS 22.0.0 (IBM SPSS Statistics, New York, USA).

RESULTS

females had significantly lower DSMQ scores compared to males (40 vs. 36, P=0.015) while median DSMQ score was highest in participants with tertiary level of education (P=0.017), and those who earned the highest annual income (P=0.007). The DSMQ´s behaviour scales showed a notable negative correlation with HbA1c (-0.565, P < 0.001). More females (80.3%) than males (56.3%) had high HbA1C (X2=6.44, P=0.016).

CONCLUSION

diabetes self-management using DSMQ showed significant correlation with glycaemic control. Male sex, higher income, and higher level of education are associated with better self-management and glycaemic control.

Psychometric Properties of the Persian Version of the Diabetes Self-Management Questionnaire for Patients with Type 2 Diabetes in Iran

Background:

Diabetes self-management questionnaire (DSMQ) is among the relatively new tools with comprehensive structure measuring various dimensions of self-care behaviors in diabetic patients. This study was carried out to evaluate psychometric properties of Persian version of DSMQ.

Methods:

A cross-sectional study was carried out from January to March 2017 among patients with type 2 diabetes mellitus (T2DM) referred to urban health centers, in Kerman, southeastern Iran. Data were collected from 589 patients using DSMQ. The DSMQ was translated into Persian by forward and backward translation method. Cronbach's alpha method and intraclass correlation coefficient (ICC) were used to measure internal consistency and test-retest reliability, respectively. In addition, construct validity was assessed by confirmatory factor analysis and exploratory factor analysis (EFA).

Results:

The sum-scale Cronbach's α of DSMQ was equal to 0.82 for 30 participants. The mean inter-item correlation and mean item-total correlation of “Sum Scale” (SS) were equal to 0.21 (standard deviation (SD) = 0.22) and 0.53 (SD = 0.19), respectively. All items had item-total correlations higher than 0.30 except items 7, 11, and 15. For “SS,” ICC was obtained as 0.93. EFA revealed a four-factor model accounting for 62.5% of the total variance. All indices were acceptable for the modified DSMQ with four factors (χ² = 134.33, degrees of freedom = 89, P = 0.001, comparative fit index = 0.97, root mean square error of approximation = 0.044, Tucker-Lewis index = 0.96, and normal fit index = 0.92).

Conclusions:

The Persian version of DSMQ was found to have acceptable reliability and validity for assessing self-management among patients with T2DM.

Further Evidence of Psychometric Performance of the Self-care of Diabetes Inventory in Adults With Type 1 and Type 2 Diabetes

BACKGROUND

The Self-care of Diabetes Inventory (SCODI) is a theory-based tool that measures self-care, a key strategy in the appropriate treatment of diabetes. However, despite the clinical differences between people with Type 1 Diabetes Mellitus (T1DM) and Type 2 Diabetes Mellitus (T2DM), the psychometric properties of the SCODI were only tested in mixed samples.

PURPOSE

This study aims to test the psychometric performances of the SCODI in two separate groups of adults with T1DM and T2DM.

METHODS

This is a secondary analysis from two previous multicentre cross-sectional observational studies involving patients with T1DM (n = 181) and T2DM (n = 540). We tested dimensionality with confirmatory factor analysis and reliability with a multidimensional model-based coefficient for every scale of the SCODI: self-care maintenance, self-care monitoring, self-care management, and self-care self-efficacy.

RESULTS

We found that the SCODI showed the same dimensionality, with minimal variation in factor loadings for each factor and each scale among T1DM and T2DM groups. High reliability for each scale in both groups was also found (self-care maintenance: T1DM = 0.86, T2DM = 0.83; self-care monitoring: T1DM = 0.84, T2DM = 1.00; self-care management: T1DM = 0.87, T2DM = 0.86; self-care self-efficacy: T1DM = 0.88; T2DM = 0.86).

CONCLUSION

The SCODI can be used for measuring self-care in people with T1DM, T2DM, or mixed groups using identical scoring procedures. Considering the well-known differences between Type 1 and Type 2 diabetes diseases and patients' characteristics, our results support the generalizability of the self-care theory on which the instrument is based.

Analysis of the Impact of Disease Acceptance, Demographic, and Clinical Variables on Adherence to Treatment Recommendations in Elderly Type 2 Diabetes Mellitus Patients

This project aimed to analyze the impact of disease acceptance and selected demographic and clinical factors on the adherence to treatment recommendations in elderly type 2 diabetes mellitus patients. The observational study was performed using standardized research questionnaires: the Acceptance of Illness Scale (AIS), the Self-Care of Diabetes Inventory (SCODI), and the Adherence in Chronic Diseases Scale (ACDS). Two hundred patients with T2DM were studied (age M = 70.21 years, SD = 6.63 years). The median degree of disease acceptance was 29 (min-max = 8-40) and the median level of adherence was 24 (min-max = 13-28). Disease acceptance was a significant (p = 0.002) independent predictor of the odds of qualifying for non-adherence OR = 0.903, 95% CI = 0.846-0.963. The respondents gave the lowest scores for glycemic control (Mdn = 38.99, min-max = 8.33-150), and health control (Mdn = 55.88, min-max = 11.76-100). A one-way ANOVA showed that the non-adhering patients were significantly older compared to the adherence group and were taking significantly more diabetes pills per day. The level of disease acceptance was average, but it turned out to be an independent predictor of adherence. Therefore, it is justified to use psychological and behavioral interventions that are aimed at increasing the level of diabetes acceptance in elderly people with T2DM. It is important to have a holistic approach to the patient and to take actions that consider the patient's deficits in the entire biopsychosocial sphere. The obtained result confirmed the legitimacy of interventions aimed at increasing the level of disease acceptance in this group of patients.

Psychometric properties of medication adherence instruments in cardiovascular diseases and type 2 diabetes mellitus: systematic review protocol

BACKGROUND

The pharmacological treatment of cardiovascular diseases and type 2 diabetes mellitus reduces the risk of cardiovascular events.; however, most patients do not adhere to the treatment. There are several self-reported measures for assessing medication adherence. Identifying the instruments with the best psychometric evidence is essential for selecting an accurate measure. The aim of this study is to critically assess, compare and synthesize the quality of the measurement properties of patient-reported outcome measures to access medication adherence among patients with cardiovascular diseases and/or type 2 diabetes mellitus.

METHODS

This protocol is reported according to Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) and the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines. The following databases will be searched: Web of Science, SCOPUS, PubMed, CINAHL, EMBASE, LILACS, PsycINFO and ProQuest.

DISCUSSION

This review will provide a detailed assessment of the measurement properties of self-reported medication adherence instruments in patients with cardiovascular diseases and/or type 2 diabetes mellitus to support clinical practice and research.

The internal realities of individuals with type 2 diabetes-Psychological disposition in self-management behaviour via grounded theory approach

BACKGROUND

A paradigm shift in the disease management of type 2 diabetes is urgently needed to stem the escalating trends seen worldwide. A "glucocentric" approach to diabetes management is no longer considered a viable option. Qualitative strategies have the potential to unearth the internal psychological attributes seen in people living with diabetes that are crucial to the sustenance of self-management behaviour. This study aims to identify and categorize the innate psychological dispositions seen in people with type 2 diabetes in relation to self-management behaviour.

METHODS

We adopted a grounded theory approach to guide in-depth interviews of individuals with type 2 diabetes and healthcare professionals (HCP) at a regional primary care clinic in Malaysia. Twenty-four people with type 2 diabetes and 10 HCPs were recruited into the study to examine the inner narratives about disease management. Two focus group discussions (FGD) were also conducted for data triangulation.

RESULTS

Participants' internal dialogue about the management of their disease is characterized by 2 major processes- 1) positive disposition and 2) negative disposition. Optimism, insight, and awareness are important positive values that influence T2D self-care practices. On the other hand, constructs such as stigma, worries, reservations, and pessimism connote negative dispositions that undermine the motivation to follow through disease management in individuals with type 2 diabetes.

CONCLUSIONS

We identified a contrasting spectrum of both constructive and undesirable behavioural factors that influence the 'internal environment' of people with type 2 diabetes. These results coincide with the constructs presented in other well-established health belief theories that could lead to novel behavioural change interventions. Furthermore, these findings allow the implementation of psychosocial changes that are in line with cultural sensitivities and societal norms seen in a specific community.

Effect of patients beliefs about medications on adherence to drugs in diabetic patients attending family medicine outpatient clinic in Ismailia, Egypt

Background

Adherence affected by many factors in the patient or in the treatment. One of these factors is beliefs about medicine, which is modifiable. This study aimed to assess the effect of beliefs about medicines on adherence to medications in diabetic patients.

Methods

It is a cross-sectional descriptive-analytic study, conducted between March 2019 and June 2019, in Family medicine outpatient clinic, Suez Canal University, Egypt. A consecutive sample of diabetic patients presented to the clinic in the period of study was included until fulfilling sample size (82 patients). They filled validated questionnaires of the Morisky Medication Adherence Scale, Beliefs about Medicine, and socio-demographic characteristics.

Results

About half of the patients were non-adherent (54.9%). The necessity beliefs mean was 18.6, while the median was 20, concerns beliefs mean was 14.2, while the median was 14, overuse beliefs mean was 12.2, while the median was 13, finally mean and median of harm score was 11.0. There was a statistically significant relationship between age, education, concern, and harm score with adherence (p = 0.04, 0.02, < 0.001, and 0.03). Age was a positive predictor of adherence; and concern beliefs score was a negative predictor of adherence.

Conclusions

Physicians should inquire about their patient medication beliefs and its effect on patient adherence to discover and solve concerns of diabetic patients to improve non-adherence.

Self-care in Iranian patients with diabetes: A systematic review and meta-analysis

OBJECTIVES

Self-care is a major factor in managing diabetes. This study aimed to determine the self-care status of Iranian patients with diabetes and to estimate the percentage of self-care in these individuals through a systematic review and meta-analysis.

METHODS

In this systematic review and meta-analysis 53 domestic articles published in Farsi and English were evaluated. We conducted database searches in domestic and foreign databases of Scientific Information Database (SID), MagIran, Google Scholar, Web of Science, Pub Med, and Scopus with no time limit. Data analysis was performed in Stata version 12 using meta-analysis method and the random effects model.

RESULTS

A total of 50 articles (53 groups) with a sample size of 9565 were systematically reviewed. The percentage of self-care in patients with diabetes was reported to be 48.86 (95% confidence interval [CI]: 43.79-53.94). According to the results, the percentage of self-care score was higher in patients with type I diabetes (55.53) when compared with patients with type II diabetes (49.26).

CONCLUSIONS

Since patients with diabetes obtained only half of the self-care score and given the importance of self-care in controlling and treating diabetes, it is necessary to perform actions to improve self-care such as benefiting from health facilities, and social and family support.

Assessment of Psychological Distress in Adults With Type 2 Diabetes Mellitus Through Technologies: Literature Review

Background

The use of technological devices can support the self-management of individuals with type 2 diabetes mellitus (T2DM), particularly in addressing psychological distress. However, there is poor consistency in the literature regarding the use of psychological instruments for the web-based screening of patients’ psychological distress and subsequent monitoring of their psychological condition during digital interventions.

Objective

This study aims to review previous literature on the types of psychological instruments delivered in digital interventions for assessing depression, anxiety, and stress in patients with T2DM.

Methods

The literature review was conducted using the PsycINFO, CINAHL and PubMed databases, in which the following terms were considered: diabetes mellitus, measure, assessment, self-care, self-management, depression, anxiety, stress, technology, eHealth, mobile health, mobile phone, device, and smartphone.

Results

In most studies, psychological assessments were administered on paper. A few studies deployed self-reporting techniques employing automated telephonic assessment, a call system for screening and monitoring patients’ conditions and preferences, or through telephone interviews via interactive voice response calls, a self-management support program leveraging tailored messages and structured emails. Other studies used simple telephone interviews and included the use of apps for tablets and smartphones to assess the psychological well-being of patients. Finally, some studies deployed mood rating scales delivered through tailored text message–based support systems.

Conclusions

The deployment of appropriate psychological tools in digital interventions allows researchers and clinicians to make the screening of anxiety, stress, and depression symptoms faster and easier in patients with T2DM. Data from this literature review suggest that mobile health solutions may be preferred tools to use in such digital interventions.

Psychometric properties of patient-reported outcome measures of self-management for cancer survivors: a systematic review protocol using COSMIN methodology

INTRODUCTION

Self-management is an important strategy for cancer survivors. Evaluating self-management is essential for planning nursing interventions that promote self-management and for measuring the contribution of nursing to health outcomes. Many patient-reported outcome measures (PROMs) have been designed and used to assess self-management in cancer survivors. However, it is unclear which PROM has the best reliability and validity. Therefore, the goal is to systematically review the psychometric properties of existing self-management PROMs and determine which PROM is best for cancer survivors.

METHODS AND ANALYSIS

This systematic review will be conducted according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines for systematic reviews of PROMs. Ten electronic literature databases (PubMed, EMBASE and so on) and two websites for PROMs will be searched from inception to 1 March 2020. Studies testing the psychometric properties of PROMs assessing self-management for cancer survivors, published in either English or Chinese, will be included. Two independent reviewers determined the eligibility of the studies and will independently extract the data. Risk of bias will be assessed using the COSMIN risk-of-bias checklist, and the quality of the results will be assessed using specific COSMIN quality criteria.

ETHICS AND DISSEMINATION

It is not necessary to obtain ethical approval for this systematic review protocol. The results will be published in a peer-reviewed journal and presented at a relevant conference.

Risk assessments and structured care interventions for prevention of foot ulceration in diabetes: development and validation of a prognostic model

BACKGROUND

Diabetes-related foot ulcers give rise to considerable morbidity, generate a high monetary cost for health and social care services and precede the majority of diabetes-related lower extremity amputations. There are many clinical prediction rules in existence to assess risk of foot ulceration but few have been subject to validation.

OBJECTIVES

Our objectives were to produce an evidence-based clinical pathway for risk assessment and management of the foot in people with diabetes mellitus to estimate cost-effective monitoring intervals and to perform cost-effectiveness analyses and a value-of-information analysis.

DESIGN

We developed and validated a prognostic model using predictive modelling, calibration and discrimination techniques. An overview of systematic reviews already completed was followed by a review of randomised controlled trials of interventions to prevent foot ulceration in diabetes mellitus. A review of the health economic literature was followed by the construction of an economic model, an analysis of the transitional probability of moving from one foot risk state to another, an assessment of cost-effectiveness and a value-of-information analysis.

INTERVENTIONS

The effects of simple and complex interventions and different monitoring intervals for the clinical prediction rules were evaluated.

MAIN OUTCOME MEASURE

The main outcome was the incidence of foot ulceration. We compared the new clinical prediction rules in conjunction with the most effective preventative interventions at different monitoring intervals with a 'treat-all' strategy.

DATA SOURCES

Data from an electronic health record for 26,154 people with diabetes mellitus in one Scottish health board were used to estimate the monitoring interval. The Prediction Of Diabetic foot UlcerationS (PODUS) data set was used to develop and validate the clinical prediction rule.

REVIEW METHODS

We searched for eligible randomised controlled trials of interventions using search strategies created for Ovid® (Wolters Kluwer, Alphen aan den Rijn, the Netherlands), MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials. Randomised controlled trials in progress were identified via the International Standard Randomised Controlled Trial Number Registry and systematic reviews were identified via PROSPERO. Databases were searched from inception to February 2019.

RESULTS

The clinical prediction rule was found to accurately assess the risk of foot ulceration. Digital infrared thermometry, complex interventions and therapeutic footwear with offloading devices were found to be effective in preventing foot ulcers. The risk of developing a foot ulcer did not change over time for most people. We found that interventions to prevent foot ulceration may be cost-effective but there is uncertainty about this. Digital infrared thermometry and therapeutic footwear with offloading devices may be cost-effective when used to treat all people with diabetes mellitus regardless of their ulcer risk.

LIMITATIONS

The threats to the validity of the results in some randomised controlled trials in the review and the large number of missing data in the electronic health record mean that there is uncertainty in our estimates.

CONCLUSIONS

There is evidence that interventions to prevent foot ulceration are effective but it is not clear who would benefit most from receiving the interventions. The ulceration risk does not change over an 8-year period for most people with diabetes mellitus. A change in the monitoring interval from annually to every 2 years for those at low risk would be acceptable.

FUTURE WORK RECOMMENDATIONS

Improving the completeness of electronic health records and sharing data would help improve our knowledge about the most clinically effective and cost-effective approaches to prevent foot ulceration in diabetes mellitus.

The validity of the diabetes self-management questionnaire (DSMQ) in Hungarian patients with type 2 diabetes

BACKGROUND

A wide range of measuring instruments are available for diabetes self-management. According to several studies, a relatively new instrument, the diabetes self-management questionnaire (DSMQ), shows a consistent relationship with outcomes of diabetes treatment as well, such as glycated hemoglobin (HbA1c). Furthermore, the questionnaire is short, but covers the main aspects of diabetes management. Given the increasing prevalence of diabetes in Hungary, our goal was to adapt this user-friendly questionnaire and analyze its validity.

METHODS

After the standard translation process, we analyzed a sample of 221 people. The construct validity of the questionnaire was tested with HbA1c and body mass index. Morisky Medication Adherence Scale-8 values were tested via Pearson correlations. Known-groups validity of the DSMQ in relation to groups based on glycemic control levels was investigated using one-way ANOVA.

RESULTS

The "sum scale" of the questionnaire and the HbA1c values show an inverse relationship (r = - 0.253, p < 0.01). Body mass index was related to the "sum scale" (r = - 0.214, p < 0.01) and to the "physical activity" (r = - 0.219, p < 0.01), while questionnaire results reflecting medication adherence correlated with the "glucose management" (r = - 0.291, p < 0.01), "health-care use" subscale (r = 0.236, p < 0.01) and the "sum scale" (r = 0.281, p < 0.01). A significant difference (F = 6.225, p = 0.002) was found between the DSMQ mean scores of the three groups, defined by good, medium, and poor glycemic control levels.

CONCLUSIONS

The Hungarian version of the DSMQ was considered a valid tool for the measurement of diabetes self-management. With its help, problematic areas of self-management could be uncovered, and interventions can be improved.

Psychometric Testing of an Indonesian-Version Diabetes Self-Management Instrument

Background

Self-management is one of the vital elements in diabetes management for adults with Type 2 diabetes mellitus (T2DM). Although the number of people with T2DM in Indonesia has risen, clinical understanding of the problems related to practicing diabetes self-management (DSM) is limited because of the lack of a valid measurement instrument. The 35-item Diabetes Self-Management Instrument (DSMI-35) is one instrument widely used in research to assess DSM-related behavior among patients with diabetes.

Purpose

This study was designed to translate the psychometric properties of the Indonesian version of the DSMI-35 and evaluate the efficacy of this instrument in a sample of Indonesian adults with T2DM.

Methods

Forward and backward translation processes were used to translate the DSMI-35 into Indonesian (IDN-DSMI). Then, the translation equivalence, content validity, face validity, construct validity, and internal consistency were assessed using a sample of 222 Indonesian adults with T2DM from eight public health centers. Confirmatory factor analysis was used to test the data.

Results

The confirmatory factor analysis confirmed that the 35 items all had acceptable goodness of fit. Although the analysis supported removing several of the items, removal of these items was not theoretically justified. The average variance extracted was acceptable, and composite reliability was satisfied. The Cronbach's alpha was .96 for the IDN-DSMI and .84–.93 for the subscales. The significant interitem correlations between some items were consistent with the findings of other previous studies.

Conclusions/Implications for Practice

The IDN-DSMI is a valid and reliable instrument that may be used to measure DSM behavior in Indonesian patients with T2DM in primary healthcare settings.

How do self-care maintenance, self-care monitoring, and self-care management affect glycated haemoglobin in adults with type 2 diabetes? A multicentre observational study

PURPOSE

To evaluate how self-care maintenance, self-care monitoring, and self-care management affect glycated haemoglobin in type 2 diabetes mellitus patients and to set cut-off points of the Self-Care of Diabetes Inventory scales using glycated haemoglobin as outcome of interest.

METHODS

A secondary analysis of a previous multicentre observational cross-sectional study was conducted. Overall, 540 adults with type 2 diabetes mellitus confirmed diagnosis were involved. Socio-demographic and clinical data were collected. Self-care maintenance, self-care monitoring, and self-care management were measured by the Self-Care of Diabetes Inventory. Linear regression models were performed to assess the relationship between self-care maintenance, self-care monitoring, and self-care management and glycated haemoglobin. Receiver operating characteristics curves were carried out to identify the best cut-off score for each self-care scale considering glycated haemoglobin >7% as outcome of interest.

RESULTS

Self-care monitoring and self-care management were associated to glycated haemoglobin in both patients without (self-care monitoring p = 0.0008; self-care management p = 0.0178) and with insulin therapy (self-care monitoring p = 0.0007; self-care management p = 0.0224). Self-care maintenance was associated to glycated haemoglobin in patients without insulin therapy (p = 0.0118). Cut-off scores providing the best performance were 70 points for self-care maintenance and self-care monitoring, and 60 points for self-care management.

CONCLUSIONS

Self-care maintenance, self-care monitoring, and self-care management differently affect glycated haemoglobin in patients with type 2 diabetes mellitus. Clinicians could implement tailored interventions to improve glycaemic control considering the lacking area of self-care.

A New Self-management Scale with a Hierarchical Structure for Patients with Type 2 Diabetes

PURPOSE

The aims of this study were to develop a new instrument for measuring self-management with a hierarchical structure [the Diabetes Self-Management Scale (DSMS)] in patients with type 2 diabetes, and evaluate its psychometric properties.

METHOD

The DSMS instrument was developed in three phases: (1) conceptualization and item generation; (2) content validity and pilot testing; and (3) field testing of its psychometric properties. A convenience sample of 473 participants was recruited in three university hospitals and one regional health center, South Korea.

RESULTS

Exploratory and confirmatory factor analyses yielded two second-order component models explaining the common variance among six first-order factors. Principal axis factoring with a varimax rotation accounted for 60.88% of the variance. Confirmatory factor analysis of the hierarchical structure revealed the following fit indices: χ²/df = 1.373, standardized root-mean-square residual = .050, goodness-of-fit index = .935, incremental fit index = .975, comparative fit index = .974, and root-mean-square error of approximation = .039. All Cronbach' α values for internal consistency exceeded the criterion of .70. All of the intraclass correlation coefficients for test-retest reliability exceeded .70 except that for the taking-medication subscale. The components of the DSMS were moderately correlated with the comparator measures of self-efficacy and health literacy administered for convergent validity.

CONCLUSION

The DSMS is a new instrument for measuring the complex nature of self-management in patients with type 2 diabetes, comprising 17 items scored on a five-point Likert scale. The DSMS exhibits satisfactory psychometric properties for five reliability and validity metrics, and so is a suitable instrument to apply in both research and clinical practices.

Factors Associated with High Patient Activation Level among Individuals with Metabolic Syndrome at a Primary Care Teaching Clinic

Background: High activation level has been associated with higher education background, better self-rated health status, and having adequate health literacy. However, there is a gap in the literature regarding the level of activation and the factors associated with it among patients with metabolic syndrome (MetS) in the Malaysian primary care setting. Objectives: This study aims to determine activation levels and the factors associated with high activation among individuals with MetS in primary care. Methods: A cross-sectional study was conducted at a university primary care clinic. Patient activation was measured using the Patient Activation Measure®-13 Malay version. Activation levels were dichotomized into "low activation" (levels 1 and 2) and "high activation" (levels 3 and 4). To determine the factors associated with high activation, simple logistic regressions (SLogR) followed by multiple logistic regressions (MLogR) were performed. Results: Of 333 participants, 280 (84.1%) were included in the final analysis. The mean activation score was 59.4 (SD ±10.20) and 61.8% had high activation level. Two variables were found to be significant on MLogR. Those who were employed have the odds of 3.135 (95% CI 1.442-6.816) of having high activation compared with those who were unemployed. Those with good self-reported health status have the odds of 6.482 (95% CI 1.243-33.792) of having high activation compared to those with poor self-reported health status. Conclusions: The majority of participants had high activation levels. Those who were employed and those who had good self-reported health status were more likely to have high activation levels. Findings of this study could be used to develop patient activation interventions to improve self-management skills among individuals with MetS in primary care. These may include problem solving support, individualized care plans, peer or family support, and skill building. Those in high activation group can be trained to become mentors to support their peers who have low activation level.

Association between subthreshold depression and self-care behaviours in adults with type 2 diabetes: A protocol for a cross-sectional study

AIMS AND OBJECTIVES

To examine the association between subthreshold depression and self-care behaviours in adults with type 2 diabetes (T2D) attending a tertiary healthcare service.

BACKGROUND

Diabetes is a global public health problem. Self-care behaviours are a fundamental element in managing diabetes as adherence to self-care activities is associated with improved glycaemic control. Depression in T2D is associated with decreased adherence to self-care behaviours. Adults with subthreshold depression in diabetes may have difficulties in achieving metabolic control. Further, people with subthreshold depression have an increased risk of developing major depression. Few studies have examined the association between subthreshold depression and self-care behaviours.

DESIGN

A cross-sectional study.

METHODS

The study will be conducted among 384 adults diagnosed with T2D for at least a year attending their routine outpatient appointment at Tribhuvan University Teaching Hospital in Nepal. Convenience sampling will be used to recruit study participants. Data will be collected via face-to-face interviews and a medical record review. Self-care behaviours will be assessed using the Summary of Diabetes Self-care activities and subthreshold depression will be determined using the Patient Health Questionnaire- 9. Covariates in the study include sociodemographic and clinical factors, diabetes knowledge, perceived social support and self-efficacy. This paper complies with the STROBE reporting guideline for cross-sectional studies.

RESULTS

We will use multiple linear regression to examine the association between subthreshold depression and each self-care behaviours (i.e. diet, physical activity, foot care, blood glucose testing and medication) and total self-care behaviour.

CONCLUSIONS

Effective management of diabetes requires adherence to self-care behaviours. The findings of the study will help in identifying an effective way to improve diabetes self-care.

RELEVANCE TO CLINICAL PRACTICE

Our observations will inform nursing research and practice by providing evidence about how subthreshold depression may influence self-care behaviours.

A systematic review of nudge theories and strategies used to influence adult health behaviour and outcome in diabetes management

BACKGROUND

Diabetes is a chronic disease associated with a variety of complications, and nudging may be a potential solution to improve diabetes control. Since nudging is a new concept, no review of literature on nudging diabetic patients into improving their health behaviour has been done. Therefore, we aim to collate a list of nudge intervention and determine the context in which nudging is successful.

METHODS

We adopted a two-arm search strategy comprising the search of literature databases and snowballing using relevant search terms. We summarized patient characteristics, the nudge intervention, according to nudging strategies, delivery mode and their outcomes. The conditions present in effective nudge interventions were assessed and reported.

RESULTS

We retrieved 11,494 studies from our searches and included 33. An additional five studies were added through snowballing. Studies included utilized framing (n=5), reminders (n=10), gamification (n=2), social modelling (n=5) and social influence (n=16). Studies on reminders and gamification were more likely to have a statistically significant outcome. The targeted health behaviours identified were medication adherence, physical activity, diet, blood glucose monitoring, foot care, self-efficacy, HbA1c and quality of life. Of these, studies with adherence to medication, foot care practice and quality of life as targeted health behaviours were more likely to show a statistically significant outcome.

CONCLUSION

Nudging has shown potential in changing health behaviour of patients with diabetes in specific context. We identified two possible factors (delivery mode and patient characteristics) that may affect the effectiveness of nudge intervention.

Polish Adaptation of the Self-Care of Diabetes Inventory (SCODI)

PURPOSE

As the guidelines indicate, education and self-care in diabetic patients are essential elements in the treatment process. The efficient evaluation of the level of self-care will enable the patient's needs to be identified and education and care to be optimised. The Self-Care of Diabetes Inventory (SCODI) is a valid and reliable tool which can measure self-care behaviours among patients with diabetes. The purpose of this study was to assess the reliability of the Polish version of the SCODI.

METHODS

The World Health Organization (WHO) translation protocol was used for the translation and cultural adaptation of the English version of the SCODI into Polish. The study included 276 Polish patients with type 2 diabetes (mean age 61.28±12.02 years). There were 145 men and 131 women in the study. The internal consistency of the SCODI was evaluated using Cronbach's Alpha.

RESULTS

The original four actor tool structure was confirmed. The mean overall levels of self-care in the four SCODI scales in the study group were self-care maintenance (67.66 pts; SD=18.55), self-care monitoring (61.81 pts; SD=24.94), self-care management (54.65 pts; SD=22.98) and self-care confidence (62.86 pts; SD=20.87). The item-total correlations were positive, so there is no need to change the scales of any of the questions. The overall consistencies for individual scales were assessed using Cronbach's Alpha: self-care maintenance (0.759), self-care monitoring (0.741), self-care management (0.695) and self-care confidence (0.932). Exploratory factor analysis and item factor loadings of the individual items ranged from 0.137 to 0.886 and, with two exceptions (questions number 23 and 32), were statistically significant (p<0.05).

CONCLUSION

The SCODI questionnaire has acceptable internal consistency and reliability in assessing self-care among diabetic patients in the Polish population. This reliable research tool can be managed in planned studies of Polish patients with diabetes.

Self-care in People with Type 2 Diabetes Mellitus Research Protocol of a Multicenter Mixed Methods Study (SCUDO)

About 11% of the adult global populations is estimated to be living with type 2 diabetes mellitus (T2DM) by 2040. T2DM requires people to make decisions regarding complex therapeutic regimes, to maintain their well-being and quality of life, to manage symptoms and to reduce disease complications. All these behaviours, requiring knowledge, motivation, experience, and skills, have been referred to the concept of self-care. The intricacy and multidimensionality of T2DM self-care requires a complex approach to its overall comprehension. This Embedded Mixed Method study aims to investigate the experience of self-care in Type 2 Diabetes Mellitus adult patients. It comprises a prospective observational design, and an interpretive description. Quantitative data will be collected with validated questionnaires from 300 patients at baseline and once a year for two years on: diabetes self-care, quality of life, diabetes related distress, and sleep quality. Socio-demographic and clinical data will be collected from medical records. Qualitative data will be collected using semi-structured interviews on circa 10-20 patients, at baseline and once a year for two years, analysed according to interpretive description. Quantitative and qualitative data will be analysed separately and then merged and interpreted. This study will expand our understanding of self-care in people with T2DM. The expected outcome will be a better understanding of the effect of self-care on glycaemic control and therefore clinical outcomes and costs.

Patient-reported outcome measures for diabetes self-care: A systematic review of measurement properties

OBJECTIVES

The aims of the present systematic review were to identify currently available patient-reported outcome measures for diabetes self-care that have been psychometrically evaluated and to evaluate their measurement properties.

DESIGN

A systematic literature review with a meta-analysis.

DATA SOURCES

A systematic literature search was conducted of the MEDLINE, EMBASE, and CINAHL databases.

REVIEW METHODS

The updated COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) was applied using the following steps to evaluate the measurement properties of the diabetes self-care measures: (1) evaluating the methodological quality, (2) evaluating either quantitatively summarized or quantitatively pooled data against criteria for good measurement properties, and (3) the evaluating the quality of evidence by applying the modified Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

Among 8434 articles yielded by the database search, 27 full-text articles that reported 34 studies of 13 different patient-reported outcome measures were included in this systematic review. The Diabetes Self-Management Instrument demonstrated the best content validity, with sufficient moderate-quality evidence for relevance, comprehensiveness, and comprehensibility. The Diabetes Self-Management Instrument exhibited sufficient moderate-quality evidence for structural validity and internal consistency, and sufficient high-quality evidence for convergent validity of hypothesis testing and sufficient low-quality evidence for reliability. The eight-item Summary of Diabetes Self-Care Activities-Revised was the most frequently investigated and shortest instrument with sufficient high-quality evidence for structural validity and internal consistency. However, the sufficient but very-low-quality comprehensiveness and the inconsistent very-low-quality comprehensibility for content validity, and the insufficient low-quality evidence for reliability must be considered when selecting this instrument.

CONCLUSIONS

None of the identified diabetes self-care instruments appears to be universally superior to the others. The Diabetes Self-Management Instrument might be the best based on current evidence, but this requires further evaluation of the measurement of invariance across languages. The eight-item Summary of Diabetes Self-Care Activities-Revised is the shortest instrument, but current evidence with regards to its content validity and reliability needs to be considered before applying this instrument. Further studies are recommended to evaluate the reliability, measurement error, and responsiveness of the diabetes self-care measurements.

The impact of provision of self-monitoring of blood glucose supplies on self-care activities among patients with uncontrolled Type 2 diabetes mellitus: A prospective study

AIMS

Self-monitoring of blood glucose (SMBG) is an important self-care activity for patients with Type 2 diabetes mellitus (T2DM) to achieve glycaemic control. The aim of this study was to evaluate the impact of providing SMBG supplies on self-care among patients with uncontrolled T2DM.

METHODS

This was a six-month, prospective study conducted in two primary care institutions. Patients ≥21 years old with uncontrolled T2DM (HbA1c > 7.0%) and polypharmacy (≥5 chronic medications) were included. All participants were given a free blood glucometer, test strips, and lancets, and were invited to consult pharmacists to learn about SMBG. The Summary of Diabetes Self-Care Activities questionnaire was administered at baseline and at six months.

RESULTS

A total of 167 patients were recruited and 150 (89.8%) completed the study. At six months, significant improvements from baseline were observed for overall self-care (+0.58, p = 0.008), glycemic control (-0.41%, p < 0.001) and all specific self-care activities. The mean change in the SMBG score in all the participants was found to have a strong positive correlation with the mean change in the overall self-care score (r_s = 0.580, p = 0.01).

CONCLUSIONS

Provision of SMBG supplies was effective in improving self-care among patients with uncontrolled T2DM, including non-insulin-treated patients.

Development and Psychometric Validation of an Instrument to Identify Barriers to Self-Care Among Spanish Patients With Type 2 Diabetes on the Basis of Theory of Planned Behavior

BACKGROUND

Several instruments are available to evaluate barriers to self-care in people with type 2 diabetes, but with significant psychometric weaknesses and poor theoretical background.

OBJECTIVES

To develop and psychometrically validate a questionnaire to identify barriers to self-care in this population on the basis of the theory of planned behavior.

METHODS

The study was carried out in 15 primary healthcare centers belonging to the Public Health Care System in Andalusia (Spain). After content validity was confirmed, an initial pilot study was undertaken (n = 54) and the model was evaluated in 2 samples of 205 subjects each to test its configural and metric invariance by confirmatory factor analysis. Internal consistency, test-retest reliability, criterion validity, and interpretability were carried out following COSMIN standards.

RESULTS

A 4-factor instrument (intention, subjective norms, perceived control, and attitudes) with 15 items was obtained with a good fit: goodness-of-fit index = 0.92, comparative fit index = 0.93, and root mean square error of approximation = 0.043 (90% confidence interval 0.034-0.052). Cronbach α was 0.78, and test-retest reliability was adequate (intraclass correlation coefficient 0.73; P < .0001). The instrument revealed an adequate criterion validity depending on the treatment complexity and level of metabolic control. Thus, participants with poor self-care scores were more likely to suffer from diabetes-related complications (odds ratio 1.91; 95% confidence interval 1.15-3.1).

CONCLUSIONS

A theory-driven instrument is suitable for its use with Spanish people with type 2 diabetes to assess their self-care needs and make tailored recommendations for lifestyle modifications on the basis of their behavioral determinants.

Literacy in health and self-care in people with type 2 diabetes mellitus

ABSTRACT Objective: To evaluate the effect of educational intervention in the adherence to self-care activities and functional health literacy and numeracy in people with type 2 diabetes mellitus. Methods: This was a quasi-experimental study conducted in two units of the Brazilian Family Health Strategy, involving people with diabetes. Educational interventions occurred in three meetings, weekly, lasting 60 minutes on average. Data were collected using the Questionário de Autocuidado com o Diabetes, before and after the interventions. Results: 55 people participated in the study. After the interventions, the greatest difference for a better adherence to self-care was the item “inspecting the inside of the shoes before putting them on”, with 3.29 days in the week delta at analytical level. The worst was “taking insulin shots as recommended”, with 0.00 days a week delta at basic level. Conclusion: Educational interventions had a positive effect on adherence to self-care and functional literacy in health.

Generalizability of the Self-Care of Diabetes Inventory Across Cultures and Languages: Italy and the United States

Measuring self-care behaviors is crucial in diabetes research worldwide. Having a common measure of self-care represents an unmet need limiting the development of the science. The Self-Care of Diabetes Inventory was developed to address limitations of previous tools that were not theoretically grounded, strong in psychometrics, and clinically validated. However, the generalizability and comparability of the Self-Care of Diabetes Inventory has not been tested across cultures and languages. The aim of this study was to test the invariance of the Self-Care of Diabetes Inventory measurement model between Italy and the United States. Data from two multicenter cross-sectional studies were used. Two diabetes clinics and two hospitals in Italy and the United States were involved. We enrolled 200 adults in Italy and 226 in the United States, all with a confirmed diagnosis of type 1 or type 2 diabetes. The Self-Care of Diabetes Inventory was used to measure self-care maintenance, monitoring, and management behaviors as described in the middle range theory of self-care of chronic illness. Configural, metric, scalar, and strict invariance were tested for each scale. Three of the four measurement equivalence levels were supported in the three Self-Care of Diabetes Inventory Scales, whereas strict invariance-the highest level-was reached only by the Self-Care Maintenance and Self-Care Monitoring Scales. Clear support for the use of the Self-Care of Diabetes Inventory in diabetes research was provided. Cross-national comparisons of self-care between groups of Italian and U.S. patients are supported, based on the invariance of the measurement model. Aggregation of research data obtained using the Self-Care of Diabetes Inventory across countries could support knowledge development in the field of diabetes self-care.

Clinical and socio-demographic determinants of inadequate self-care in adults with type 1 diabetes mellitus: the leading role of self-care confidence

AIMS

To describe self-care maintenance, monitoring, and management behaviors in adults with type 1 diabetes (T1DM), and to identify clinical and socio-demographic determinants of inadequate self-care.

METHODS

A cross-sectional study was conducted in two diabetes outpatient clinics in Italy. Clinical and socio-demographic characteristics were collected from the medical records of 181 consecutively enrolled T1DM patients. The Self-Care of Diabetes Inventory was used to measure self-care maintenance, self-care monitoring, self-care management and self-care confidence. A standardized 0-100 score was used for each self-care dimension. A score < 70 was considered inadequate self-care. Three multiple logistic regression models were run to find determinants of inadequate self-care maintenance, monitoring, and management.

RESULTS

The majority of patients had adequate self-care maintenance (74%; n = 134), self-care monitoring (68.5%; n = 124) and self-care confidence (87.3%; n = 158), while self-care management was adequate for only a minority (34.8%; n = 63). The odds of inadequate self-care maintenance increased by 4.5 times when self-care confidence was inadequate (OR adjusted 4.589; 95% CI 1.611-13.071; p = 0.004). The odds of inadequate self-care monitoring increased four times when patients had inadequate self-care confidence (OR adjusted 4.116; 95% CI 1.457-11.628; p = 0.008). Inadequate self-care confidence increased the odds of performing inadequate self-care management more than five times (OR adjusted 5.313; 95% CI 1.143-24.686; p = 0.033).

CONCLUSIONS

Self-care management is commonly inadequate in adults with T1DM. Self-care confidence is the most important determinant of self-care behaviors in this population. Educational interventions are recommended to improve self-care confidence in adults with T1DM.

Psychometric Evaluation of the Farsi Version of the Self-Care of Diabetes Inventory in Iranian Patients with Diabetes

BACKGROUND

Lifelong self-care is important in particular for patients with diabetes, because preventing diabetes complications can help maintain the quality of life and independence of diabetic patients. Currently, there are 16 self-care tools, the majority of which focus on one part of self-care. Therefore, the aim of this study was to evaluate the psychometric properties of the Farsi Self-Care of Diabetes Inventory (F-SCODI) in Iran.

METHODS

A cross-sectional study was performed on 400 diabetic patients who were selected by convenience sampling to complete the F-SCODI. In this regard, construct validity was assessed using exploratory factor analysis. Additionally, the internal consistency of the F-SCODI was evaluated by McDonald's omega coefficient and Cronbach's alpha; whereas its stability was assessed by a test re-test approach.

RESULTS

In total, four factors were extracted (activity-nutritional behavior, smoking avoidance behavior, illness-related behaviors, and health-promoting behaviors) in the dimension of self-care maintenance, three factors (symptom monitoring, symptom assessment, and symptom recognition) in the dimension of self-care monitoring, two factors (autonomous self-care and consultative self-care) in the self-care management dimension, and two factors (task-specific self-care confidence and persistence self-care) in the dimension of confidence. In this regard, the overall consistencies of the four dimensions were 0.809, 0.767, 0.590, and 0.886, respectively.

CONCLUSION

This study indicated that the Farsi version of SCODI had acceptable internal consistency and reliability as well as content and construct validity. Given the acceptable psychometric properties, this tool can be used in future studies in Iranian patients with diabetes.

Beliefs and Practices of Patients with Diabetes toward the Use of Herbal Therapy

This study aimed to assess the prevalence of using herbal therapy and the beliefs toward the use of this type of therapy among patients with diabetes. It also aimed to identify the significant predictors of these beliefs and the factors that increase the likelihood of using herbal therapy. A descriptive cross-sectional design was used. A convenience sample comprised 310 patients with diabetes. Sixty-seven (21.6%) of the participants used herbal therapy. The mean beliefs score was 3.72 and ranged from (0–12). Linear regression showed that beliefs were significantly predicted by self-care, attending workshops, education level, and number of complications. The logistic regression showed that the lower the self-care and the higher the beliefs, the more likelihood the patient uses herbal therapy. Informing patient through individualized diabetes education influences the patient's beliefs and promotes self-care. This education program should target mainly those patients with low self-care, high number of complications, lower educational level and having more complications.

Exercise intervention alleviates nerve injury by the suppression of inflammatory mediator expression via the TLR4/NF-κB signaling pathway

Spinal cord injury (SCI) may cause changes that have damaging effects on sensation and functionality. However, methods for the significant amelioration of SCI-reduced nerve injury are lacking. Previous studies have indicated that reasonable and effective exercise may promote the recovery of injured nerves. Therefore, the aim of the present study was to investigate the ability of exercise to improve recovery following SCI and the underlying mechanism. A rat model was used to evaluate the effects of two different periods of exercise intervention on recovery following SCI. The exercise intervention comprised 15 or 30 min/day passive walking for 30 days. ELISA measurements were used to analysis the plasma levels of inflammatory cytokines. Reverse transcription-quantitative polymerase chain reaction and western blot analyses were performed to examine the levels of proteins and mRNAs associated with nuclear factor (NF)-κB-related signaling. In addition, histological examination and immunostaining were used to evaluate the neural injury and associated indicators. The results indicated that severe SCI induced a peripheral inflammatory response and increased the expression of inflammatory cytokines. In addition, the SCI-induced nerve injury was associated with increased glial fibrillary acidic protein (GFAP) expression and the upregulation of Toll-like receptor 4 (TLR4)/NF-κB signaling, which may further aggravate the inflammatory responses induced by SCI. However, the exercise intervention decreased SCI-induced GFAP expression and reduced the activation of the TLR4/NF-κB signaling pathway compared with that of SCI model rats that did not exercise. Furthermore, the exercise intervention inhibited the release of inflammatory cytokines into the serum. These results indicate that exercise treatment reduces inflammation and glial activation, and may be beneficial to recovery following SCI.

Socio-demographic and clinical determinants of self-care in adults with type 2 diabetes: a multicentre observational study

AIMS

To describe self-care as defined by the Middle Range Theory of Self-Care of Chronic Illness and to identify clinical and socio-demographic determinants in a T2DM population.

METHODS

A multicentre observational cross-sectional study was conducted involving 540 adults with a confirmed diagnosis of T2DM from six outpatient diabetes services in Italy. Socio-demographic and clinical data were collected from medical records. The Self-Care of Diabetes Inventory (SCODI) was used to measure self-care maintenance, monitoring, management, and confidence dimensions. For each separate scale, scores were standardized 0-100 with higher SCODI scores indicating better self-care; a score ≥ 70 is adequate. Multiple quantile regression models were performed to identify determinants of each self-care dimension.

RESULTS

Self-care maintenance (median = 81.3) and self-care confidence (median = 79.5) were adequate in most of the subjects. Self-care monitoring was adequate in only half of the sample (median = 70.6). Self-care management was poor (median = 59.4). Lower self-care maintenance was associated with lower self-care confidence (p < 0.001). Lower self-care monitoring was associated with being male (p < 0.001), having lower self-care confidence (p < 001), and having diabetes for < 10 years (p < 0.001). Lower self-care management was associated with being male (p = 0.002), being older (p = 0.005), having a low income (p = 0.030), being employed (p = 0.008), having missed diabetes education in the last year (p = 0.002), and lower self-care confidence (p < 0.0001). Lower self-care confidence was associated with having diabetes for < 10 years (p = 0.008), and having at least one comorbid condition (p = 0.006).

CONCLUSIONS

Determinants of self-care maintenance, monitoring, management and confidence include both clinical and socio-demographic variables. Modifiable determinants such as self-care confidence and diabetes self-care management education could be used to tailor interventions to improve diabetes self-care.

A randomized controlled study to evaluate the effect of pharmacist-led educational intervention on glycemic control, self-care activities and disease knowledge among type 2 diabetes patients: A consort compliant study protocol

BACKGROUND

Diabetes self-care activities, like, healthy diet, regular exercise, self-monitoring of blood glucose, and rational use of medicines are considered to play a vital role in establishing euglycemia. Health literacy among type 2 diabetes mellitus (T2DM) patients in Pakistan is very low, which is the most likely cause for poor clinical outcomes. This study is designed to investigate the impact of pharmacist-led educational intervention on glycemic control, self-care activities and disease knowledge among T2DM patients in Pakistan.

METHODS

In this randomized controlled trail, effectiveness of a 6-month pharmacist-led educational intervention will be examined on glycemic control, diabetes self-care activities and disease knowledge of 80 adult T2DM patients (age >30 years) with poorly controlled T2DM (HbA1c> 7%), after randomizing them into intervention and control groups, at diabetes care clinic of Capital Hospital Islamabad, Pakistan.

RESULTS

The primary outcome is change in patients' HbA1c, whereas, changes in self-care activities and patients' disease knowledge are the secondary outcomes. After baseline assessment of their self-care activities and disease knowledge by using validated Urdu versions of Diabetes Self-management Questionnaire (DSMQ) and Diabetes Knowledge Questionnaire (DKQ), respectively, interventional group patients will be supplemented with a face-to-face pharmacist-led educational intervention, whereas, the control group will receive usual care. Intervention arm patients will be educated successively at their first follow-up visit (12th week) and telephonically after every 4 weeks. All assessments will be made at baseline and end of trail for both intervention and control groups. Multivariate general linear model will be applied to analyze the effects of the intervention.

CONCLUSION

Glycemic control in T2DM patients requires optimum self-care activities. This study is an attempt to improve self-care behaviors among poorly controlled T2DM patients who are at higher risk of diabetes-associated late complications.
