Diabetes-related distress and quality of life among people with type 2 diabetes at primary care level in Brazil

PURPOSE

Living with diabetes can be challenging, particularly when it comes to dealing with psychological distress and requiring self-care directives. Patients may feel frustrated, angry, overwhelmed, and discouraged. This study aimed to investigate the diabetes-related distress and quality of life among people with type 2 diabetes mellitus (T2DM).

METHODS

A cross-sectional study carried out at the Clinical Research Centre at the University of Campinas, Brazil, between September 2020 and April 2021. Patients answered data regarding demographic and clinical variables, the Brazilian version of the Diabetes Distress Scale and the Diabetes Quality of Life (QOL) Measure by telephone contact. The data were managed using the RedCap System. For statistical analysis of the data, the Mann-Whitney and Kruskal-Wallis tests were applied for comparisons, and the Chi-square test for associations. The correlations were evaluated using the Spearman correlation coefficient.

RESULTS

Out of the 302 participants we recruited, 50.33% exhibited significant diabetes-related distress. Those with elevated diabetes-related distress scores had shorter education levels (p < 0.05), lower HbA1c levels (p < 0.05), and lower total scores in Diabetes QOL Measure (p < 0.0001), particularly in the QOL impact (p < 0.0001), social/vocational worry (p < 0.05), and diabetes worry (p < 0.0001) subscales compared to the group with the lowest diabetes-related distress.

CONCLUSION

Elevated diabetes-related stress scores significantly affect patients' QOL. Therefore, early screening of individuals at risk for this condition, using well-coordinated protocols, could mitigate adverse QOL effects and enhance their overall experience during disease management.

Revising the Diabetes Distress Scale for Use Among Adults in the Dominican Republic: Findings From Cognitive Interviews

PURPOSE

The purpose of this study is to assess the content validity of the Diabetes Distress Scale (DDS) among adults with type 2 diabetes mellitus (T2DM) living in rural Dominican Republic communities.

METHODS

Researchers conducted cognitive interviews with 20 adults with T2DM to assess how they answered a Spanish version of the 17-item DDS, a commonly used scale to measure diabetes distress. Interviews were done iteratively to allow for revisions and testing of those revisions with the participants. Analysis involved field notes, text summaries, and cognitive coding.

RESULTS

The sample was 55% women, had a mean age of 55 years, and came from 10 rural communities. The cognitive interviews highlighted needed changes across comprehension, judgment (clarity), recall, response process, and logical/structural issue domains. Participants generally understood the DDS; however, 4 items, the introduction, and response options were revised to improve participant response. The items were revised using wording from the participants themselves. By changing certain terms and splitting a couple of items, these items improved comprehension and judgment. The introduction was simplified from 2 paragraphs to 1 to reduce structural issues (ie, scale's features), and the response options were reduced from 6 options to 5 options to improve the response process.

CONCLUSIONS

Based on iterative study findings, the researchers propose expanding the 17-item DDS to 19 items to improve participant response. Revising the DDS to account for cultural and structural changes will improve clinical and public health understanding of the role of diabetes distress on T2DM management among Dominican adults.

Patient-reported outcome measures for assessing health-related quality of life in people with type 2 diabetes: A systematic review

Patient-Reported Outcome Measures (PROMs) are important tools to assess outcomes relevant to patients, with Health-Related Quality Of Life (HRQOL) as an important construct to be measured. Many different HRQOL PROMs are used in the type 2 diabetes field, however a complete overview of these PROMs is currently lacking. We therefore aimed to systematically describe and classify the content of all PROMs that have specifically been developed or validated to measure (aspects of) HRQOL in people with type 2 diabetes. A literature search was performed in PubMed and EMBASE until 31 December 2021. Studies on the development or validation of a PROM measuring HRQOL, or aspects of HRQOL, in people with type 2 diabetes were included. Title and abstract and full-text screening were conducted by two independent researchers and data extraction was performed independently by one of the researchers. Data were extracted on language in which the PROM was developed, target population, construct(s) being measured, names of (sub)scales and number of items per (sub)scale. In addition, all PROMs and subscales were classified according to specific aspects of HRQOL based on the Wilson & Cleary model (symptom status, functional status, general health perceptions) to aid researchers in PROM selection. In total 220 studies were identified that developed or validated PROMs that measure (aspects of) HRQOL in people with type 2 diabetes. Of the 116 unique HRQOL PROMs, 91 (of the subscales) measured symptom status, 60 measured functional status and 26 measured general health perceptions. In addition, 16 of the PROMs (subscales) measured global quality of life. 61 of the 116 PROMs (subscales) also include characteristics of the individual (e.g. aspects of personality, coping) or environment (e.g. social or financial support) and patient-reported experience measures (PREMs, e.g. measure of a patient's perception of their personal experience of the healthcare they have received, e.g. treatment satisfaction), which are not part of the HRQOL construct. Only 9 of the 116 PROMs measure all aspects of HRQOL based on the Wilson & Cleary model. Finally, 8 of the 116 PROMs stating to measure HRQOL, measured no HRQOL construct. In conclusion, a large number of PROMs are available for people with type 2 diabetes, which intend to measure (aspects of) HRQOL. These PROMs measure a large variety of (sub)constructs, which are not all HRQOL constructs, with a small amount of PROMs not measuring HRQOL at all. There is a need for consensus on which aspects of HRQOL should be measured in people with type 2 diabetes and which PROMs to use in research and daily practice. PROSPERO: CRD42017071012.

Content Validity of Patient-Reported Outcome Measures Developed for Assessing Health-Related Quality of Life in People with Type 2 Diabetes Mellitus: a Systematic Review

PURPOSE OF REVIEW

We aimed to systematically evaluate the content validity of patient-reported outcome measures (PROMs) specifically developed to measure (aspects of) health-related quality of life (HRQOL) in people with type 2 diabetes. A systematic review was performed in PubMed and Embase of PROMs measuring perceived symptoms, physical function, mental function, social function/participation, and general health perceptions, and that were validated to at least some extent. Content validity (relevance, comprehensiveness, and comprehensibility) was evaluated using COSMIN methodology.

RECENT FINDINGS

We identified 54 (different versions of) PROMs, containing 150 subscales. We found evidence for sufficient content validity for only 41/150 (27%) (subscales of) PROMs. The quality of evidence was generally very low. We found 66 out of 150 (44%) (subscales of) PROMs with evidence for either insufficient relevance, insufficient comprehensiveness, or insufficient comprehensibility. For measuring diabetes-specific symptoms, physical function, mental function, social function/participation, and general health perceptions, we identified one to 11 (subscales of) PROMs with sufficient content validity, although quality of the evidence was generally low. For measuring depressive symptoms, no PROM with sufficient content validity was identified. For each aspect of HRQL, we found at least one PROM with sufficient content validity, except for depressive symptoms. The quality of the evidence was mostly very low.

Translation, cross-cultural adaptation, and validation of the Canadian Diabetes Risk Questionnaire for the Brazilian population

OBJECTIVE

The aim of this study was to translate, cross-culturally adapt, and validate the Canadian Diabetes Risk Questionnaire for use in Brazilian Portuguese.

METHODS

This is a Questionnaire validity study conducted at a private university. The Brazilian version of the Canadian Diabetes Risk Questionnaire was developed by means of the processes of translation, back-translation, committee review, and pretesting. Test-retest reliability was measured using the intraclass correlation coefficient and kappa coefficient. Internal consistency was measured using Cronbach's alpha. For construct validity, the total score of the Canadian Diabetes Risk Questionnaire was correlated with the Diabetes Knowledge Scale and the Diabetes Mellitus Risk Questionnaire. Ceiling and floor effects were also evaluated in the present study.

RESULTS

For construct validity and floor and ceiling effect measurements, a total sample of 100 participants was used. For reliability, a subsample of 34 participants out of the total sample was used. We identified adequate values for reliability (kappa between 0.46-1.00 and ICC 0.96) and internal consistency (Cronbach's alpha 0.80). There were significant correlations between the Canadian Diabetes Risk Questionnaire and the Diabetes Mellitus Risk Questionnaire (rs=0.370, p<0.001), but not the Diabetes Knowledge Scale (rs= -0.162). No ceiling or floor effects were found.

CONCLUSION

We concluded that in accordance with the best international recommendations, the Brazilian version of the Canadian Diabetes Risk Questionnaire has adequate psychometric properties.

Psychometric Evaluation of the Diabetes Distress Scale in Patients with Type 2 Diabetes in Turkey

The objective of the research was to evaluate the validity and reliability of the Diabetes Distress Scale in patients with type 2 diabetes in Turkey. Materials and Methods. Our study was conducted between September 2016 and January 2017 and included 170 patients with type 2 diabetes. The Personal Information Form and Diabetes Distress Scale were used as a data collection tool. Statistical analysis was performed using SPSS 23.0 and SAS package program. Results. According to the results of the research, Cronbach’s alpha reliability for the total scale was 0.91. The model fit indices for the revised confirmatory factor analysis model failed to meet the criteria for acceptability: the GFI was 0.8185, the CFI was 0.9316, the Bentler - Bonett (1980) NFI was 0.9005, and the RMSEA was 0.1067. In our study, exploratory factor analysis provided support for the three-factor model: [I] emotional and regimen-related distress, [II] health professional-related distress, [III] diabetes-related interpersonal distress. Conclusions. When the translation and cultural adaptation process have been considered, the Diabetes Distress Scale is a valid and reliable tool for the Turkish community. It is recommended to be used in the studies and clinical trials.

Translation, cross-cultural adaptation and validation of the Finnish Diabetes Risk Score (FINDRISC) for use in Brazilian Portuguese: questionnaire validity study

BACKGROUND

The Finnish Diabetes Risk Score (FINDRISC) is a questionnaire that was developed by Finnish researchers to track the risk of diabetes.

OBJECTIVE

To translate, cross-culturally adapt and validate the FINDRISC for use in Brazilian Portuguese.

DESIGN AND SETTING

Questionnaire validity study conducted at a private university.

METHODS

The Brazilian version of the FINDRISC was developed through the processes of translation, back-translation, committee review and pre-testing. Test-retest reliability was measured using the intraclass correlation coefficient (ICC), kappa coefficient, standard error of measurement (SEM) and minimum detectable change (MDC). Internal consistency was measured using Cronbach's alpha. For construct validity, the total score of the FINDRISC was correlated with the Diabetes Knowledge Scale (DKN-A) and Diabetes Mellitus Risk Questionnaire (QRDM). Ceiling and floor effects were also evaluated in the present study.

RESULTS

For construct validity and floor and ceiling effect measurements, a total sample of 107 participants was used. For reliability, a subsample of 51 participants out of the total sample was used. We identified adequate values for reliability (kappa ≥ 0.79 and ICC = 0.98) and internal consistency (Cronbach's alpha = 0.84). Regarding the error inherent in the FINDRISC, we found SEM = 8.02% and MDC = 22.44%. There were significant correlations between the FINDRISC and the QRDM (r = 0.686) and DKN-A (r = -0.216). No ceiling or floor effects were found.

CONCLUSION

The Brazilian version of the FINDRISC has adequate psychometric properties that are in accordance with the best international recommendations.

Diabetes-Specific Questionnaires Validated in Brazilian Portuguese: A Systematic Review

Two researchers conducted independent searches on five different electronic databases: PubMed/MEDLINE, Embase, SciELO, LiLACS and Web of Science. Studies were selected that covered cross-cultural adaptation methodology and validation in Brazil with type 1 and type 2 diabetes patients of any age. After reading the full-text articles, data related to psychometric characteristics were extracted from each study selected. Reliability was assessed with Cronbach's α (Cα). The initial searches identified 2,211 studies. After exclusions, 26 were included, covering a total of 31 questionnaires. Questionnaires were grouped into 11 domains based on their main focus of interest: adherence (n = 8), quality of life (n = 7), diabetes knowledge (n = 3), hypoglycemia (n = 3), self-efficacy (n = 3), satisfaction with pharmaceutical services (n = 1), emotional stress (n = 2), hope (n = 1), attitude towards diabetes (n = 1), perception of disease severity (n=1), and risk of developing diabetes (n = 1). This study identified and reviewed all of the diabetes-specific questionnaires that have been validated for Brazilian Portuguese, which should facilitate selection of the most appropriate instrument for each domain of interest in future research and clinical settings.

Relatively young T1D adults using fixed doses of insulin have higher diabetes distress levels in a sample of patients from a Brazilian tertiary hospital

BACKGROUND

Elevated rates of anxiety and depressive symptoms in Type 1 Diabetes patients (T1D) and high rates of diabetes-specific distress (DD) have been shown. Several factors may be responsible for increase the DD levels such as age, life changes, lack of familiar support, education, insulin regimens (IRs) and chronic complications. The goals of this study were: 1-to compare DD levels, anxiety and depressive symptoms according to age (< and ≥ 25 years old), 2-to evaluate the association between DD levels, anxiety and depressive symptoms and IRs, and 3-to evaluate the association between DD levels, anxiety and depressive symptoms and chronic complications.

METHODS

In a cross-sectional study, T1D patients receiving outpatient care at Unicamp tertiary hospital were included. Inclusion criteria were age at least 18 years old and diagnosis of T1D for 6 months. Exclusion criteria were cognitive impairment, major psychiatric disorders, severe diabetes-related complications, and pregnancy. Depressive symptoms were evaluated by the depression subscale of the Hospital Anxiety and Depression Scale (HAD-D) and the anxiety symptoms by the anxiety subscale of the same instrument (HAD-A). DDS scale assessed DD. Glycemic control was evaluated by HbA1C. The latest lipid panel results were recorded and IRs and chronic complications were obtained through chart review.

RESULTS

Of all 70 patients, 70% were younger than 25 years old. No differences were found between two groups according to gender, education, and income (p = 0.39, p = 0.87, and p = 0.52, respectively). HbA1c mean was 10% in both groups (p = 0.15). Older patients had higher levels of total DD and physician DD than younger (p = 0.0048 and p = 0.0413; respectively).Total DD and DD on subscales 1 and 2 were higher in patients using fixed doses of insulin compared to variable doses according to carbohydrates count (p = 0.0392, p = 0.0383 and p = 0.0043, respectively). No differences were found between anxiety and depressive symptoms and age and IRs. Similarly, no differences were found among DD levels, anxiety and depressive symptoms in patients with and without chronic complications.

CONCLUSIONS

When providing education and care for T1D patients, health providers should consider age, patient's developmental stage, with its related demands and the burden of insulin regimen.

Low empowerment and diabetes regimen distress are related to HbA1c in low income type 1 diabetes patients in a Brazilian tertiary public hospital

BACKGROUND

Adults with type 1 diabetes (T1D) have a high risk of developing depressive symptoms and diabetes-related distress (DD). Low socioeconomic level is associated with increased risk of poor self-management, treatment difficulties and psychological distress. The goals of this study were to document the frequency of major depressive disorder (MDD), high depressive symptoms and high DD, to assess levels of empowerment and to determine the association with each of these measures and glycemic control in a low-income Brazilian sample of adults with T1D.

METHODS

In a cross-sectional study, inclusion criteria were age > 18 years and diagnosis of T1D > 6 months. Exclusion criteria were cognitive impairment, history of major psychiatric disorders, severe diabetes-related complications and pregnancy. Diagnoses of MDD were made using interview-based DSM-5 criteria. Depressive symptoms were evaluated by the depression subscale of the Hospital Anxiety and Depression Scale (HAD-D). The Diabetes Distress Scale (DDS) assessed DD. Empowerment levels were evaluated by the Diabetes Empowerment Scale short form (DES-SF). Glycemic control was measured by HbA1c. The latest lipid panel results were recorded. Number of complications was obtained from medical records.

RESULTS

Of the 63 T1D patients recruited, 36.5% were male, mean age was 31.5 (± 8.9), mean number of complications was 1 (± 1.1), and mean HbA1c was 10.0% (± 2). Frequency of MDD was 34.9% and 34.9% reported high depressive symptoms. Fifty-seven percent reported clinically meaningful DD. High diabetes regimen distress and low empowerment were associated to HbA1c (p = 0.003; p = 0.01, respectively). In multivariate analyses, lower empowerment levels were associated to higher HbA1c (beta - 1.11; r-partial 0.09; p value 0.0126). MDD and depressive symptoms were not significantly correlated with HbA1c in this expected direction (p = 0.72; p = 0.97, respectively).

CONCLUSIONS

This study showed high rates of MDD, high depressive symptoms and high DD and low levels of empowerment in this low income population. Empowerment and diabetes regimen distress were linked to glycemic control. The results emphasize the need to incorporate the psychological and psychosocial side of diabetes into strategies of care and education for T1D patients.

Clinical and sociodemographic variables associated with diabetes-related distress in patients with type 2 diabetes mellitus

Objective:

To evaluate the relation between diabetes-related distress and the clinical and sociodemographic characteristics of type 2 diabetes mellitus patients.

Methods:

A cross-sectional study based on a secondary analysis of data collected at a specialized care outpatient center in Brazil. Participants completed a questionnaire on sociodemographic and clinical characteristics and the Brazilian version of the Diabetes Distress Scale (B-DDS).

Results:

About 31% of the 130 eligible patients reported diabetes distress, and the mean B-DDS score was 2.6. Multiple regression analysis showed the B-DDS score was positively correlated with marital status (p=0.0230), use of diet and physical activities for diabetes management (p=0.0180), and use of insulin therapy (p=0.0030). The "emotional burden", "regimen-related distress", and "interpersonal distress" domains from B-DDS were associated with the use of insulin therapy (p=0.0010), marital status (p=0.0110), and the presence of three or more comorbidities (p=0.0175).

Conclusion:

These findings suggest the clinical and sociodemographic variables are relatively weak predictors of diabetes-related distress. The highest scores in the B-DDS were observed in the emotional burden domain, indicating the presence of diabetes distress among the participants of the study.

Objetivo:

Avaliar a relação entre o estresse relacionado ao diabetes e as características clínicas e sociodemográficas de pacientes com diabetes mellitus do tipo 2.

Métodos:

Estudo transversal com base na análise secundária de dados coletados em um ambulatório de atendimento terciário no Brasil. Os participantes preencheram um questionário sobre as características sociodemográficas e clínicas, e a versão brasileira da Diabetes Distress Scale (B-DDS).

Resultados:

Aproximadamente 31% dos 130 pacientes elegíveis relataram estresse relacionado ao diabetes, e a média do escore da B-DDS foi de 2,6. O modelo de regressão múltipla mostrou que a pontuação B-DDS foi positivamente correlacionada com o estado civil (p=0,0230), realização de dieta e atividades físicas (p=0,0180), e uso de insulina (p=0,0030). Os domínios da B-DDS "carga emocional", "estresse relacionado ao regime terapêutico" e "estresse nas relações interpessoais" foram associados a uso de insulina (p=0,0010), estado civil (p=0,0110) e presença de três ou mais comorbidades (p=0,0175).

Conclusão:

Estes resultados sugerem que as variáveis clínicas e sociodemográficas são preditores relativamente fracos para o estresse relacionado ao diabetes. No domínio "carga emocional", foi observada a maior pontuação da B-DDS, indicando a presença do estresse relacionado ao diabetes entre os pacientes deste estudo.

Diabetes distress: understanding the hidden struggles of living with diabetes and exploring intervention strategies

Diabetes distress is a rational emotional response to the threat of a life-changing illness. Distinct from depression, it is conceptually rooted in the demands of diabetes management and is a product of emotional adjustment. Diabetes distress has been found to be significantly associated with glycated haemoglobin (HbA1c) level and the likelihood of an individual adopting self-care behaviours. The lack of perceived support from family, friends and healthcare professionals significantly contributes to elevated diabetes distress, and this issue tends to be overlooked when designing interventions. Pioneering large-scale research, DAWN2, gives voices to the families of those with diabetes and reaffirms the need to consider psychosocial factors in routine diabetes care. Structured diabetes education programmes are the most widely used in helping individuals cope with diabetes, but they tend not to include the psychological or interpersonal aspects of diabetes management in their curricula. The need for health practitioners, irrespective of background, to demonstrate an understanding of diabetes distress and to actively engage in discussion with individuals struggling to cope with diabetes is emphasised.
