Positive emotional health and diabetes care: concepts, measurement, and clinical implications

Psychosocial predictors of short-term glucose among people with diabetes: A narrative review

Type 1 and type 2 diabetes are metabolic disorders that require one to manage one's blood glucose levels on a daily basis through a series of behaviorally complex tasks. Research shows that psychosocial factors, including mood, stress, and social relationships, have a significant influence on one's ability to maintain these disease management routines and achieve healthy blood glucose levels. However, researchers have typically approached these questions from a between-person perspective. Here, we argue for greater consideration of short-term, within-person links of psychosocial factors-including mood, stress, and social interactions-to glucose outcomes. Drawing from existing social and health psychology theories, we put forth an organizing theoretical framework describing how psychosocial experiences may operate on glucose outcomes over subsequent hours. We then review the small but burgeoning literature of intensive longitudinal studies that have examined the short-term effects of negative affect, positive affect, stress, and social interactions on glucose outcomes. Findings showed somewhat stronger links for negative affect and stress compared to positive affect and social interactions, but studies varied greatly in their methodologies, making direct comparisons challenging. A number of findings, particularly in the social interaction literature, depended on dispositional or contextual factors, further complicating interpretation. There was little investigation of the mechanistic pathways that may connect psychosocial factors to glucose outcomes, and few studies conducted lagged analyses to probe the directionality of these links. We conclude by proposing best practices for future research that will address the key weaknesses in the extant literature.

Evaluation of the Psychosocial Status of Patients With Type 2 Diabetes Mellitus and Their Treating Physicians Using the Glycemic Happiness Scale: A Multicentric, Cross-sectional Study

BACKGROUND

The purpose of this study was to evaluate the psychosocial status of patients with type 2 diabetes (T2D) and treating physicians using a novel Glycemic Happiness (GH) scale.

METHODS

This was a real-world, prospective, multicentric, cross-sectional observational study. Male and female participants aged ≥ 18 years with a clinical diagnosis of T2D were eligible to take part. Additionally, the physicians with extensive T2D patient experience were enrolled in the study.

RESULTS

The study included a total of 400 participants of T2D and 27 physicians. The patient population consisted of 213 (53.3%) men and 187 (46.7%) women, with a mean age of 54.29 ± 12.05 years. The proportions of patients and physicians who were found to be happy were 50.5% and 90.8%, respectively. A statistically significant difference was found in the mean value of the GH score of insulin and oral antidiabetic drugs (OAD) for the physician component (P=0.0160). Although no significant difference in GH score was observed between insulin and OAD usage among the patients (P=0.9564), a significant difference was observed for dosage frequency of OAD (Once daily (OD) vs. three times daily (TID) (P=0.0034) and twice daily (BID) vs. TID (P=0.0324)). In the multiple regression analysis, GH in patients was found to be associated with glycated hemoglobin (HbA1c) and postprandial glucose (PPG) values.

CONCLUSIONS

High glucose levels and OAD dosage frequency have been negatively associated with GH in patients with T2D. To achieve long-term happiness and well-being in diabetes management, there is a need to focus on various aspects of GH among patients and physicians.

Increases in Psychological Stress Are Associated With Higher Fasting Glucose in US Chinese Immigrants

BACKGROUND

The majority of Chinese Americans is foreign-born, and it is well-documented that immigration to the United States (US) leads to increased risk for chronic diseases including type 2 diabetes. Increased disease risk has been attributed to changes in lifestyle behaviors following immigration, but few studies have considered the psychosocial impact of immigration upon biomarkers of disease risk.

PURPOSE

To examine associations of psychological stress and social isolation with markers of type 2 diabetes risk over time among US Chinese immigrants.

METHODS

In this longitudinal study of 614 Chinese immigrants, participants completed assessments of perceived stress, acculturative stress, negative life events, and social isolation annually at three time points. Fasting blood samples were obtained at each time point to measure blood glucose, glycated hemoglobin, and insulin resistance. Mean duration between baseline and follow-up assessments was approximately 2 years.

RESULTS

Increases in migration-related stress, perceived stress and social isolation were associated with significant increases in fasting glucose at follow-up independent of age, body mass index, length of US residence, and other potential covariates. Moreover, increases in glucose varied depending on perceived stress levels at baseline, such that those with higher baseline stress had a steeper increase in glucose over time.

CONCLUSIONS

Psychological stress and social isolation are associated with increases in fasting glucose in a sample of US Chinese immigrants. Findings suggest that the unique experiences of immigration may be involved in the risk of developing type 2 diabetes, a condition that is prevalent among US Chinese despite relatively low rates of obesity.

Psychosocial Facilitators and Barriers to Type 2 Diabetes Management in Adults: A Meta-Synthesis

BACKGROUND

Globally, the cases of type 2 diabetes are increasing, and this is largely attributed to lifestyle changes. Though diabetes is primarily a metabolic disease determined by biological factors, psychosocial aspects play a crucial role in its progression and management. However, the literature on psychosocial dimensions of diabetes management is minuscule and scattered.

OBJECTIVE

This synthesis sought to understand the psychosocial facilitators and barriers to type 2 diabetes management and coping among adults.

METHODS

We have adopted a meta-synthesis to review available qualitative studies using Pub- Med and Scopus databases. Based on inclusion criteria, we have chosen 24 studies published between 2010 and 2023. We have considered studies across countries, among which 63% of the studies included were from Western countries, and most have employed qualitative descriptive design. The selected studies were analyzed thematically using a deductive framework.

RESULTS

Six themes emerged as the psychosocial barriers and facilitators of managing and coping with type 2 diabetes: 1) cognitive-emotional factors, 2) faith, 3) constraints to behavioural change, 4) social constraints and support, 5) healthcare provider-patient relationship, and 6) awareness. Further, a conceptual framework was developed from the synthesis.

CONCLUSION

The patients' experiences evident from this synthesis signify the crucial role of psychosocial factors in diabetes management and coping. This evidence emphasizes the need for integrated care so that psychosocial aspects are addressed by healthcare providers and behavioural health professionals, which may lead to the promotion of facilitators and the minimization of barriers.

Links of positive affect and stress to HbA1c: a prospective longitudinal study

While affect is linked to a number of diabetes outcomes, the specific role of positive affect (PA) in HbA1c remains unclear. The present study examined whether PA prospectively predicted lower HbA1c among adults with type 2 diabetes and whether this relation was moderated by stress. Participants were 123 adults (44.7% female; 60.2% White, 39.8% Black) recently diagnosed with type 2 diabetes. Perceived stress, diabetes-specific distress, and PA were assessed at baseline; HbA1c was assessed at baseline (T1), six months (T2), and five years (T3). PA was cross-sectionally associated with lower HbA1c at T1 and prospectively predicted lower HbA1c at T3. PA interacted with both measures of T1 stress to predict T1 HbA1c, and PA interacted with T3 perceived stress to predict T3 HbA1c. Interactions were consistent with stress buffering. Sensitivity analyses attentuated findings, but robust evidence remained for PA as a protective factor for blood glucose five years later and for a stress-buffering effect of PA on diabetes-specific distress. Findings suggest PA may be a clinically useful indicator among adults with type 2 diabetes and may be particularly important for those experiencing the greatest stress from their disease.

Influence of Family Social Support and Diabetes Self-Efficacy on the Emotional Wellbeing of Children and Adolescents with Type 1 Diabetes: A Longitudinal Study

Type 1 diabetes (T1D) is a chronic disease that is usually diagnosed in childhood, underscoring the importance of early disease control for overall wellbeing. Our aim was to design an explanatory model of subjective emotional wellbeing in children and adolescents with T1D. A longitudinal study was conducted at the Reina Sofia University Hospital in Cordoba (Spain). A total of 151 patients (mean age = 14.50, SD = 2.67; 41.1% girls) participated at T1, while 97 participated at T2 (mean age = 14.93, SD = 2.56; 39.2% girls). Participants completed a self-report questionnaire. Descriptive, reliability, correlation, path, and mediation analyses were performed. The explanatory model showed excellent fit indices [χ² (10) = 8.62, p = 0.57, RMSEA = 0.00, 95% [0.00, 0.10], CFI = 1.00, GFI = 0.98, AGFI = 0.93, and TLI = 1.01]. The results showed significant and positive relationships between family social support and subjective emotional wellbeing and improved self-care skills. Self-efficacy presented a mediating role between family social support and subjective emotional wellbeing. Given that self-efficacy is a self-regulatory mechanism and a determinant of health, it is argued that future psychoeducational interventions could aim to improve self-efficacy to manage chronic diseases, to achieve greater emotional wellbeing in children and adolescents with T1D.

Mediating Role of Depression Between Diabetes Management Self-Efficacy and Diabetes Self-Care Behavior Among Elderly Type 2 Diabetes Mellitus Patients in China

Objective

To investigate the current status of diabetes self-care behavior and the association between depression, self-efficacy and self-care in a sample of Chinese elderly type 2 diabetes mellitus (T2DM) patients.

Methods

A cross-sectional study with a convenient sample including 240 elderly T2DM patients collected the data of demographic characteristics, diabetes self-care behavior, self-efficacy and depression status. The difference of self-care behavior in different sample characteristics was compared by independent t-test. The Personal correlation analysis was employed to examine the correlation of study variables. The method of bootstrap was used to analyze mediating role of depression.

Results

Only 22.5% of patients reported better diabetes self-care behavior and depression partly mediated the association between self-efficacy and self-care behavior. The significant coefficient of path a (B = -0.052, p < 0.001) and path b (B = -0.423, p < 0.05) indicated negative associations of self-efficacy on depression, and depression on self-care behavior. The indirect effect (Path a × b) between self-efficacy and self-care behavior through depression was significant (B = 0.022, p < 0.05), the 95% bias-corrected bootstrap confidence interval was 0.004 to 0.006. Meanwhile, the mediating role of depression was not found significant among the participants reported 60-74 years old (B = 0.104, p < 0.001). But depression completely mediated this association among the participants reported 75-89 years old (B = 0.034, p > 0.05).

Conclusion

The level of diabetes self-care behavior among the elderly T2DM patients in Dahu community of Anqing city was hardly optimistic. The self-efficacy focused intervention could be encouraged for community and clinicians to improve diabetes self-care behavior. Moreover, the prevalence of depression and T2DM is increasing in younger population. More work is needed to confirm these findings, especially conducting cohort studies on different populations.

Flourishing mental health and lifestyle behaviours in adults with Type 1 and Type 2 Diabetes Mellitus: results from the Diabetes MILES - The Netherlands Study

OBJECTIVE

To examine the associations between mental health and lifestyle in adults with type 1 and type 2 diabetes mellitus (T1DM and T2DM).

METHODS

Online survey data from the cross-sectional Diabetes MILES - The Netherlands Study was analysed, including 270 adults with T1DM and 325 with T2DM. Mental health status (flourishing, moderate and languishing) in relation to diet, physical activity, alcohol consumption and smoking was analysed with ANCOVA and logistic regressions (adjusted for confounders).

RESULTS

47% of T1DM-, and 55% of T2DM participants reported flourishing mental health. Due to an insufficient number, participants with languishing mental health were excluded. In T2DM, participants with flourishing mental health had more optimal diet quality (mean ± SEM: 70 ± 1 vs 68 ± 1 diet quality score, p = 0.015), and physical activity levels (mean ± SEM: 3484 ± 269 vs 2404 ± 273 MET minutes/week, p = 0.001) than those with moderate mental health, but did not differ with respect to alcohol consumption and smoking. In T1DM, no significant associations were found.

CONCLUSION

Only in T2DM, people with flourishing mental health had more optimal lifestyle behaviours compared to people with moderate mental health. Further research is needed to determine if mental health is more important for specific lifestyle behaviours, and if the mental health effect differs across diabetes types.

Mental Resilience, Mood, and Quality of Life in Young Adults with Self-Reported Impaired Wound Healing

The purpose of this study was to evaluate the impact of self-reported impaired wound healing on quality of life, wellbeing, and mood. It was hypothesized that individuals with impaired wound healing report significantly poorer mood compared to healthy controls. An online survey was conducted among 2173 Dutch young adults (18-30 years old) to investigate mood, neuroticism, and mental resilience. Participants were allocated to a healthy control group (N = 1728) or impaired wound healing groups comprising a wound infection group (WI, N = 76), a slow-healing wounds group (SHW, N = 272), and a group that experienced both WI and SHW (the COMBI group, N = 97). The Kruskal-Wallis test was used to compare outcomes the groups. Compared to the healthy control group, the SHW and COMBI groups, but not the WI group, reported significantly poorer mood, increased neuroticism, reduced mental resilience, and reduced quality of life. An analysis evaluating sex differences found that negative effects on stress, mental resilience, and neuroticism were significantly more pronounced among women than among men. In conclusion, self-reported impaired wound healing is associated with poorer mood and reduced quality of life. To improve future wound care, these findings advocate for an interdisciplinary approach taking into account mood effects accompanying having impaired wound healing.

Health-risk behaviours among Indigenous Australians with diabetes: A study in the integrated Diabetes Education and Eye Screening (iDEES) project

AIM

To assess the prevalence of modifiable health-risk behaviours among Indigenous Australian adults with diabetes attending a regional Victorian Indigenous primary-care clinic.

DESIGN

A cross-sectional observational single-site study.

METHODS

As part of a multi-study project we administered the Smoking, Nutrition, Alcohol consumption, Physical activity and Emotional wellbeing (SNAPE) survey tool during the study baseline visit to methodically capture health-related behavioural data in the nurse-led integrated Diabetes Education and Eye Screening (iDEES) project in a regional Indigenous primary healthcare setting between January 2018 and March 2020. This descriptive SNAPE study helps address the lack of health behaviour data for Indigenous people with diabetes.

RESULTS

Of 172 eligible adults, 135 (79%) were recruited to the iDEES study, 50 (37%) male. All participated in at least one survey. Median (range) age was 56 (46-67) years; 130 (96%) had Type 2 diabetes of median [IQR] duration 6 (2-12) years. All 135 provided smoking data; 88 (65%) completed all surveys. Forty-nine (36%) and 29 (22%) were current or former smokers, respectively; 5 (6%) met vegetable intake guidelines, 22 (25%) met fruit intake guidelines; 38 [43%] drank alcohol in the past year. On average, participants walked for ≥10 min at a time 4 days/week and sat for an average of 8 h on weekdays; 35 (40%) had minimal-mild, and 30 (34%) had moderate-severe depressive symptoms.

CONCLUSION

Suboptimal modifiable health-risk behaviours and depressive symptoms are common in Indigenous Australian adults with diabetes.

IMPACT

Orderly assessment and reporting of health-risk behaviours using a single multi-component survey instrument (SNAPE tool) during a nurse-led diabetes education clinical visit is feasible and efficient. Such data may facilitate personalised interventions and improve diabetes management at both individual and health service levels.

State of the science: A scoping review and gap analysis of adolescent insulin pump self-management

PURPOSE

Adolescent diabetes outcomes remain poor despite increased use of diabetes technologies such as insulin pump therapy. Meaningful research examining adolescent insulin pump self-management has been done, however, a summary of these self-management findings has not been published. The aim of this literature review is to map, evaluate, and summarize existing adolescent insulin pump self-management research.

METHOD

A scoping review of three databases was conducted to comprehensively report and synthesize relevant literature published before September 2019.

RESULTS

Of the 1295 titles identified, 18 articles met the inclusion criteria and were included in this scoping review. Key insulin pump self-management behaviors were featured in the literature, most notably self-monitoring of blood glucose (SMBG) and bolus frequency. Several factors were found to influence pump self-management including psychological factors, parental support and self-management transition, insulin pump education and knowledge acquisition, and environmental factors. We uncovered five gaps in the literature including: an unclear delineation of adolescent age; limited minority representation; variability in the definitions and reporting of self-management behaviors; the role of data sharing and remote monitoring was not addressed; and there remains limited inquiry into diabetes burden and distress associated with insulin pump self-management.

PRACTICE IMPLICATIONS

There exists a consensus that well-established behaviors, such as bolus and SMBG frequency, influence glycemic outcomes for adolescent insulin pump users, however, full insulin pump utilization and self-management is poorly understood. Diabetes clinicians should work to support adolescent insulin pump self-management practices by reinforcing bedrock behaviors while fostering supportive factors found to influence pump self-management.

Mental health and its associations with weight in women with gestational diabetes mellitus. A prospective clinical cohort study

OBJECTIVE

Despite the prevalence of depression in women with gestational diabetes mellitus (GDM) and the relationship between mental health (depression and well-being) and metabolic health, little is known about mental health or its metabolic impact in GDM pregnancy. This prospective clinical cohort study aimed to investigate associations between 1) well-being and depression, and 2) mental health and weight/weight gain in women with GDM.

METHODS

We included 334 pregnant women with GDM treated at a Swiss University Hospital between January 2016 and December 2018. They completed two self-report questionnaires: The World Health Organization well-being index (WHO-5) at the first (29 weeks of gestation) and last (36 weeks of gestation) GDM visits during pregnancy and the Edinburgh Postnatal Depression Scale (EPDS) at the first GDM visit. A cut-off of ≥11 was selected for this questionnaire to indicate the presence of elevated depression scores.

RESULTS

There was an inverse association between the well-being and depression total scores at the first GDM visit during pregnancy (r = -0.55; p < 0.0001). Elevated depression scores at the first GDM visit were associated with subsequent weight gain in GDM pregnancy (β = 1.249; p = 0.019).

CONCLUSION

In women with GDM, elevated depression scores during pregnancy are prospectively associated with weight gain. Depression symptoms should therefore be screened for and treated in women with GDM to reduce the risks associated with excessive weight gain during pregnancy.

Prevalence and Correlates of Positive Mental Health Among Canadian Adults With Type 1 or Type 2 Diabetes: Results From the Canadian Community Health Survey---Mental Health

OBJECTIVES

Current definitions of mental health are no longer limited to presence or absence of mental illness. Although dimensions of mental illness have been well studied among people with diabetes, little is known about positive mental health. Optimal positive mental health is referred to as "flourishing" and is characterized by happiness, psychological well-being and social well-being. Therefore, the purpose of this study was to examine the prevalence and correlates of flourishing mental health among Canadian adults diagnosed with diabetes.

METHODS

Data came from participants >19 years of age in the Canadian Community Health Survey---Mental Health 2012, a national, cross-sectional survey. Positive mental health was measured with the Mental Health Continuum---Short Form, which categorizes individuals into flourishing, moderate and languishing mental health.

RESULTS

Although the majority of participants with diabetes reported flourishing mental health (73.22%), flourishing mental health was more common among people without diabetes (76.56%). Among people with diabetes (n=2,024), those who were flourishing reported greater physical activity, better self-rated health, fewer comorbidities, less functional disability and were less likely to smoke compared with those who were not flourishing. Those who were flourishing were less likely to have a lifetime history of major depressive disorder or generalized anxiety disorder and were distinguished by some demographic characteristics.

CONCLUSION

Among people with diabetes, flourishing mental health was associated with distinct behavioural, health and sociodemographic correlates.

Mental health and its associations with glucose-lowering medication in women with gestational diabetes mellitus. A prospective clinical cohort study

AIMS

Mental health symptoms are frequent in women with gestational diabetes mellitus (GDM) and may influence glycemic control. We therefore investigated if mental health symptoms (high depression and low well-being scores) predicted a need for glucose-lowering medication and if this use of medication influenced the trajectory of mental health during pregnancy and in the postpartum period.

METHODS

We included 341 pregnant women from a cohort of GDM women in a Swiss University Hospital. The World Health Organization Well-being Index-Five was collected at the first and last GDM and at the postpartum clinical visits and the Edinburgh Postnatal Depression Scale at the first GDM and the postpartum clinical visits. Medication intake was extracted from participants' medical records. We conducted linear and logistic regressions with depression as an interaction factor.

RESULTS

Mental health symptoms did not predict a need for medication (all p ≥ 0.29). Mental health improved over time (both p ≤ 0.001) and use of medication did not predict this change (all p ≥ 0.40). In women with symptoms of depression, medication was associated with less improvement in well-being at the postpartum clinical visit (p for interaction=0.013).

CONCLUSIONS

Mental health and glucose-lowering medication did not influence each other in an unfavourable way in this cohort of women with GDM.

The Mental Status in Patients with Diabetes Mellitus Admitted to a Diabetes Clinic After Presenting in the Emergency Room: The Application of the SCL-90 Scale

BACKGROUND

Diabetes mellitus (DM) is one of the most serious public health problems, involving increasing costs worldwide. The mental state of a person with DM is varied and ever-changing, such as stress, the pressure to always do everything by the book, sadness, anger, and even denial of the disease, all these are feelings patients with DM will experience throughout their life.

AIM

The aim of our study was to assess the presence of mental and psychiatric disorders (anxiety, depressive states, paranoid ideation, phobia, obsessive-compulsive disorder) in a group of patients with DM after hospitalization in the Clinic for Diabetes, Nutrition, and Metabolic Diseases, for various exacerbations of the underlying condition, looking for possible correlations with other cardiovascular risk factors.

PATIENTS AND METHODS

Clinical and biological parameters, the presence of acute and chronic complications of the diabetic patients have been evaluated. To assess mental health, the symptom checklist (SCL)-90 questionnaire was conducted for all admitted patients.

RESULTS

We observed that the number of patients with obsessive-compulsive disorders was relatively high (23.3%), while depression was present in 17.1% of the patients. Also, 10.6% of patients had hostility and 15.6% had delusional ideation. The presence of psychiatric disorders was associated with a higher age (62 vs. 46.5 years; p <0.001), a longer diabetes duration (11 vs. 9 years; p <0.001), higher fasting glycemia (188 vs. 132 mg/dL; p <0.001) and postprandial glycemia (212 vs. 152 mg/dL; p <0.001), and triglycerides (125 vs. 110 mg/dL; p <0.001). Patients with altered mental status have shown statistically significantly more altered clinical and biological parameters compared to those without these mental disorders.

CONCLUSION

Patients with DM represent a psychologically vulnerable population, which is why they should undergo early and regular screening for both psychological and psychiatric conditions, especially at admission.

Validation of a new instrument to measure disease-related distress among patients with haemophilia

INTRODUCTION

In patients with haemophilia, general psychological distress as measured by the National Comprehensive Cancer Network (NCCN) distress thermometer has been associated with pain, disability and increased healthcare utilization.

AIMS

To develop and validate a measure of haemophilia-related distress.

METHODS

After qualitative interviews, the Hemophilia-Related Distress Questionnaire (HRDq) was developed. To validate the HRDq, adults (≥18 years) with haemophilia were enrolled, reported demographic and clinical information, and completed the HRDq and other questionnaires that measured similar constructs. Analysis included factor analysis and assessment of internal consistency using Cronbach's α, convergent validity using Pearson's correlation coefficient, and discriminant validity by comparing subgroups of patients. Test-retest reliability was assessed using an intraclass correlation coefficient (ICC).

RESULTS

Among 130 enrolled participants, 126 (median age=32.7 years) completed the 24 item HRDq in a median time of 5.4 minutes with overall HRDq scores ranging from 2 to 83 (median score=31.5; higher scores indicating higher distress). Assessment of convergent validity demonstrated a strong correlation (ρ>.60) of the HRDq total score with the NCCN Distress Thermometer, Haem-A-QoL total Score, and PROMIS-29 Profile social role domain and a mild to moderate correlation with all other questionnaire domains (.3-.59, p < .05). Distress was higher among those who had less education, were not employed, and were disabled and was not significantly different among those with severe compared with non-severe disease. Assessment of test-retest reliability demonstrated an ICC value of .84 (95% CI .71-.91) for the total score.

CONCLUSIONS

The HRDq demonstrates good internal consistency, construct and discriminant validity, and retest reliability with a low responder burden.

Distress and Type 2 Diabetes Self-Care: Putting the Pieces Together

BACKGROUND

Conflicting research emphasizes depression, diabetes distress, or well-being in relation to diabetes self-care and risk for poor health outcomes.

PURPOSE

The purpose of this study was to test whether a latent variable for general psychological distress derived from shared variance of depression symptoms, diabetes distress, and well-being predicts a latent variable of diabetes self-care and to examine evidence for unique effects once shared effects are adjusted for.

METHODS

Adults with suboptimally controlled diabetes were recruited from the South Bronx, NY, for a telephonic diabetes self-management support trial. Baseline diabetes self-care, medication adherence, depression symptoms, diabetes distress, and well-being were measured by validated self-report. Structural equation modeling specified a latent variable for general psychological distress derived from shared variance of depression symptoms, diabetes distress, and well-being. Diabetes self-care was a latent variable indicated by diet, glucose self-monitoring, and medication adherence.

RESULTS

Participants (N = 627, 65% female) were predominantly ethnic minority (70% Hispanic; 45% Black) and 77% reported household income <$20K/year. Mean (standard deviation) age = 56 (12) years; A1c = 9.1% (1.9%); body mass index = 32 (8) kg/m2. The latent variable for psychological distress was a robust predictor of poorer diabetes self-care (coefficient = -0.59 [confidence interval = -0.71, -0.46], p < .001) with good model fit. Unique paths from depression symptoms, diabetes distress, and well-being (all ps > .99) to self-care were not observed.

CONCLUSIONS

In this population of disadvantaged adults with suboptimally controlled diabetes, general psychological distress was strongly associated with poorer diabetes self-care and fully accounted for the effects of depression, diabetes distress, and positive well-being. This suggests that general distress may underlie previously reported associations between these constructs and diabetes self-care.

Difficulties with health self-management by older adults: The role of well-being

The purpose of this study was to investigate the association between three aspects of well-being (positive and negative affect, self-realization, and self-efficacy and resilience) and disease self-management or difficulties in managing care. Logistic regression models were used to analyze data from a sample of community-dwelling Medicare beneficiaries 65-years or older who participated in the National Health and Aging Trends Study and responded to well-being and engagement in health care questions (n = 1663). All three aspects of well-being were significantly associated with reduced difficulties in care management for both the participants and their family and friends who assist them. Self-efficacy and resilience had the strongest association; older adults with higher levels of self-efficacy and resilience were more likely to handle care by self. Our findings highlight the importance of incorporating strategies to enhance well-being of older adults to reduce the difficulties of managing activities necessary to stay healthy.

Immediate and Long-Term Effects of an 8-Week Digital Mental Health Intervention on Adults With Poorly Managed Type 2 Diabetes: Protocol for a Randomized Controlled Trial

Background

Diabetes is a leading cause of years of life lost and accounts for approximately one-fourth of health care dollars spent in the United States. Many of these costs are related to poor medication adherence and lack of self-care behaviors and are thus preventable. Depression, which is more prevalent among people with diabetes than in the general population, predicts poorer management of one’s diabetes, whereas positive affect predicts engaging in more positive health behaviors. Consequently, interventions that improve depression and positive affect may also improve diabetes-related outcomes among people with diabetes. Although preliminary research on the impact of such interventions among people with diabetes is promising, these studies focused primarily on in-person interventions, have had small samples, and lack long-term follow-up.

Objective

This study aims to examine the short- and long-term effects of a digital therapeutic platform focused on mental health among adults with poorly managed type 2 diabetes and elevated levels of depression.

Methods

This is a randomized controlled trial in which adults with a type 2 diabetes diagnosis, elevated hemoglobin A_1c (HbA_1c) levels (≧7), and moderate to severe depressive symptoms will be randomly assigned to a positive emotion regulation skills intervention group or a sham digital intervention with only psychoeducational content. The study will take place over 14 months, including the 8-week intervention (or control) delivered via a digital therapeutic platform (Happify Health) and follow-up assessments at 3, 6, and 12 months postintervention. Throughout the intervention and for 1 week at each postintervention follow-up, participants will complete daily assessments of diabetes-related distress, diabetes regimen adherence, and mood. Our primary outcome, HbA_1c, will be self-reported every 3 months throughout the study. Secondary and exploratory outcomes will be assessed at baseline; at 8 weeks; and at 3, 6, and 12 months postintervention.

Results

Recruitment is expected to begin in June 2020. Participants will begin the study as they are recruited and will finish in waves. The final wave of data collection from the 8-week intervention is expected for winter 2020, with the completion of the 12-month follow-up in winter 2021.

Conclusions

Although previous research suggests that in-person psychological interventions have promising effects on both psychological and physical outcomes among adults with diabetes, digital interventions can be advantageous because they are easily scalable and reduce many barriers that prevent people from seeking treatment. This trial will provide important information about the effects of a digital mental health intervention among adults with type 2 diabetes, assessing both short- and long-term effects of this intervention on HbA1c, depressive symptoms, and other diabetes-specific outcomes. If successful, this may introduce a scalable intervention that would help reduce some of the preventable costs associated with diabetes.

Development and Preliminary Validation of a New Type 1 Diabetes Adjustment Scale (DAS-1)

BACKGROUND

This study focuses on the development and validation of a new Type 1 Diabetes Adjustment Scale (DAS-1).

METHOD

A total of 204 participants aged 15-65 with type 1 diabetes completed the self-report measures of the DAS-1, which includes clinical and psychological variables.

RESULTS

Robust confirmatory factor analysis detected a unidimensional structure of the item scores. The omega coefficient was 0.91 and test-retest reliability was 0.87. Classifying subjects as in a Positive or Negative mood state, ROC analysis yielded an optimal cut-off of 50 for the DAS-1 scores, with a clinical accuracy of AUC = 0.85. The DAS-1 demonstrated evidence of good reliability and acceptable construct validity.

CONCLUSION

The DAS-1 demonstrated good clinical utility, good sensitivity and adequate specificity. Clinical and theoretical implications of these results are discussed.

The Association between Diabetes-Related Distress and Medication Adherence in Adult Patients with Type 2 Diabetes Mellitus: A Cross-Sectional Study

BACKGROUND

Type 2 diabetes mellitus (T2DM) is a major public health problem associated with distress. T2DM can affect health outcomes and adherence to medications. Little is however known about the association between diabetes distress and medication adherence among patients with T2DM in Ghana.

OBJECTIVE

The objective of the present study is twofold: to estimate distress associated with T2DM and to examine its association with medication adherence.

METHODS

A hospital-based cross-sectional study was conducted among 188 patients with T2DM recruited from a diabetes specialist outpatient clinic at the Pantang Hospital in Accra, Ghana. Data were obtained using the Problem Areas In Diabetes (PAID) scale and the Medication Adherence Report Scale.

RESULTS

The findings showed that about 44.7% of the patients showed high levels of diabetes-related distress. Poor adherence to medications was recorded in 66.5% of the patients. Patients who were highly distressed had 68% lower odds of adhering to their medications compared to those who were not (OR: 0.32, 95% CI: 0.15-0.65). A principal component analysis revealed four areas of T2DM distress which were conceptualized as negative emotions about diabetes, dietary concerns and diabetes care, dissatisfaction with external support, and diabetes management helplessness.

CONCLUSION

Our findings suggest that diabetes distress is a significant determinant of medication adherence behaviour in patients with T2DM. Thus, incorporating routine screening for distress into the standard diabetes care within the Ghanaian health system and having health practitioners adopt holistic approaches to diabetes management will be important context-specific interventions to improve adherence and health outcomes of people living and coping with T2DM.

Factors influencing participation in physical activity after dysvascular amputation: a qualitative meta-synthesis

Purpose: Identifying factors associated with physical activity after dysvascular lower limb amputation (LLA) could provide targets for improving rehabilitation outcomes. The purpose of this meta-synthesis was to identify modifiable factors that may influence physical activity after LLA, a condition characterized by amputation in the setting of older age, diabetes mellitus (DM), and/or peripheral artery disease (PAD).Methods: A systematic search of the literature identified qualitative studies exploring the perceptions of physical activity in people with lower limb amputation, older age, DM, or PAD. Qualitative rigor was assessed using the McMaster University's Guidelines for Qualitative Review. Meta-synthesis was undertaken to analyze the findings of included studies.Results: Fourteen studies of variable methodological quality were included for analysis. Three overarching factors that may influence physical activity after LLA emerged: 1) educational experiences and motivation, 2) support and self-efficacy, and 3) special concerns after lower limb amputation (e.g., prosthesis, equipment, and environment).Conclusions: Physical activity after LLA is influenced by relationships among health understanding, motivation, support, and self-efficacy in the presence of disability. Themes from this meta-synthesis can be used to develop and test behavior-based interventions to improve physical activity after LLA.Implications for rehabilitationPhysical activity participation after dysvascular lower limb amputation is complicated by the presence of chronic conditions, severe disability, and unaddressed psychosocial factors.Addressing a patient's self-efficacy, social support, motivation, and understanding during physically focused rehabilitation may improve participation in physical activity after dysvascular lower limb amputation.Rehabilitation professionals can address self-efficacy, motivation, and understanding by using collaborative, empathetic communication strategies known to enhance a patient's sense of support.

Management of patients with type 2 diabetes in cardiovascular rehabilitation

The clinical benefits of rehabilitation in cardiovascular disease are well established. Among cardiovascular disease patients, however, patients with type 2 diabetes mellitus require a distinct approach. Specific challenges to clinicians and healthcare professionals in patients with type 2 diabetes include the prevalence of peripheral and autonomic neuropathy, retinopathy, nephropathy, but also the intake of glucose-lowering medication. In addition, the psychosocial wellbeing, driving ability and/or occupational status can be affected by type 2 diabetes. As a result, the target parameters of cardiovascular rehabilitation and the characteristics of the cardiovascular rehabilitation programme in patients with type 2 diabetes often require significant reconsideration and a multidisciplinary approach. This review explains how to deal with diabetes-associated comorbidities in the intake screening of patients with type 2 diabetes entering a cardiovascular rehabilitation programme. Furthermore, we discuss diabetes-specific target parameters and characteristics of cardiovascular rehabilitation programmes for patients with type 2 diabetes in a multidisciplinary context, including the implementation of guideline-directed medical therapy.

The Role of Affect and Coping in Diabetes Self-Management in Rural Adults with Uncontrolled Diabetes and Depressive Symptoms

Many patients with diabetes have poorly controlled blood sugar levels and remain at risk for serious diabetes complications, despite access to effective diabetes treatments and services. Using the transactional model of stress and coping framework, the study investigated the contributions of affect (Positive and Negative Affect Schedule) and coping (maladaptive and adaptive coping from the Brief Cope) on diabetes self-management behaviors, namely diet and exercise. One hundred seventy-eight rural adults with uncontrolled diabetes and moderate depressive symptoms completed the measures. Multiple regression analyses demonstrated that positive affect and negative affect were significantly associated with diet and exercise, even after adjusting for diabetes severity, illness intrusiveness, and diabetes knowledge. However, two path analyses clarified that adaptive coping mediated the relationships between affect (positive and negative) and self-management behaviors (diet and exercise). Comprehensive diabetes treatments that include self-management support can assist patients in recognition and use of adaptive emotion-focused coping skills.

Affect, inflammation, and health in urban at-risk civilians

Positive and negative affect are both associated with health outcomes. Using validated measures, we examined associations between affect, self-reported measures of health, and objective measures of systemic inflammation in a cross-sectional sample of outpatient subjects recruited from an urban county hospital. Participants (n = 1055) recruited from the Grady Trauma Project in Atlanta, GA underwent standardized interviews including self-report measures of psychiatric symptoms and physical health. A subset (n = 246) consented to an assay of serum C-reactive protein (CRP). Regression models including positive affect as the predictor variable with covariates of age, gender, income, trauma load, depression and PTSD symptoms, were significantly associated with physical health domain scales of the Short Form-36 Health Survey (SF-36) of general health (R2 = 0.212; p < 0.001) and physical functioning (R2 = 0.154; p = 0.013). No association was observed using negative affect as the predictor variable. While greater serum CRP concentrations were associated with less positive affect (r = -0.137; p = 0.038), this relationship did not remain significant (p = 0.250) when controlling for demographic variables, body mass index, trauma load, and psychiatric symptoms. Future studies using larger samples or samples with more variance for CRP and positive and negative affect may be helpful in investigating the relationship between CRP and positive and negative affect. Our results support the hypothesis that positive affect contributes beneficially to physical health. Development of strategies to enhance positive affect in at-risk populations may be a meaningful way to improve their health.

Psychological interventions for behavioral adjustments in diabetes care - a value-based approach to disease control

Psychological aspects of a person, such as the personal value and belief systems, cognition and emotion, form the basis of human health behaviors, which, in turn, influence self-management, self-efficacy, quality of life, disease control and clinical outcomes in people with chronic diseases such as diabetes mellitus. However, psychological, psychosocial and behavioral interventions aimed at these groups of patients have yielded inconsistent effects in terms of clinical outcomes in clinical trials. This might have been due to differing conceptualization of health behavioral theories and models in the interventions. Assimilating different theories of human behavior, this narrative review attempts to demonstrate the potential modulatory effects of intrinsic values on cognitive and affective health-directed interventions. Interventions that utilize modification of cognition alone via education or that focuses on both cognitive and emotional levels are hardly adequate to initiate health-seeking behavior and much less to sustain them. People who are aware of their own personal values and purpose in life would be more motivated to practice good health-related behavior and persevere in them.

The Impact of a Mobile Diabetes Health Intervention on Diabetes Distress and Depression Among Adults: Secondary Analysis of a Cluster Randomized Controlled Trial

Background

Diabetes is a complex, demanding disease that requires the constant attention of patients. The burden of self-management, including different medication regimens, routine self-care activities, and provider visits, has an impact on patients’ emotional well-being. Diabetes distress and depression are two important components of emotional well-being that may negatively affect diabetes outcomes.

Objective

The aim was to determine the impact of the 1-year Mobile Diabetes Intervention Study cluster randomized clinical trial on emotional well-being measured by diabetes distress and depression among adults with type 2 diabetes (T2D).

Methods

A total of 163 adults with not-well-managed T2D were enrolled from community primary care practices. Primary care practices were cluster randomized into either a usual care control group or intervention group. Intervention participants were given a mobile phone with coaching software including a Web portal to communicate with providers. A priori established secondary outcomes included distress measured by the Diabetes Distress Scale (DDS), with subscales measuring emotional burden, interpersonal distress, physician-related distress, and regimen-related distress, as well as depression measured by the Patient Health Questionnaire (PHQ-9). Linear mixed models were used to calculate the effect of the intervention on diabetes distress levels over time, both overall and separately by sex, and to determine if the intervention affected distress or depression. The impact of total DDS on changes in HbA_1c was also studied.

Results

There were no significant treatment group effects for DDS total (baseline: P=.07; differences over time: P=.38) or for depression (P=.06 over time). Significant declines in total DDS were observed over the 12-month intervention period (P=.01). Regimen-related distress significantly decreased for all study participants (P<.001), but no significant change over time was observed for emotional burden (P=.83), interpersonal distress (P=.64), or physician-related distress (P=.73). Women in both the usual care and intervention groups were more likely to have higher overall DDS, emotional burden, physician-related distress, and regimen-related distress, but not interpersonal distress. Women also reported higher baseline depression compared to men (P=.006). Overall, depression decreased over the treatment period (P=.007), but remained unaffected by group assignment (P=.06) or by sex (P=.97). Diabetes distress had no effect on the change in HbA_1c (P=.91) over the treatment period.

Conclusions

Although we found no definitive overall or sex-specific effect of the intervention on diabetes distress or depression, this study makes an important contribution to the understanding of mobile health interventions and the impact on emotional health. Our study verified previous work that although diabetes distress and depression are highly correlated, these measures are not evaluating the same construct. Design of future mobile technology provides an opportunity to personalize, contextualize, and intervene in the emotional well-being of persons with diabetes.

Psychological Well-Being and Type 2 Diabetes

Positive psychological characteristics such as optimism, positive affect, gratitude, and related constructs may play an important role in health. In patients with type 2 diabetes (T2D), positive psychological constructs have been associated with superior medical outcomes, including better glucose control and lower mortality rates. The beneficial effects of positive psychological states in T2D are most likely mediated through health behaviors such as increased physical activity and adherence to a healthier diet. Furthermore, numerous studies with non-diabetic populations have shown that performing various positive psychological exercises (e.g., writing gratitude letters, performing acts of kindness) have led to greater well-being. Compared to other available treatments, these activities are simple and involve constructs that have been associated with superior adherence and diabetes-related outcomes. However, there has been minimal research on the use of positive psychological interventions in T2D, though small studies of related interventions have been linked to improvements in positive affect and, in some cases, greater health behavior adherence and lower blood sugar. Continued work is needed to ascertain whether positive psychology interventions can truly impact functioning, blood sugar, and overall health in this key population.

Psychological interventions for diabetes-related distress in adults with type 2 diabetes mellitus

BACKGROUND

Many adults with type 2 diabetes mellitus (T2DM) experience a psychosocial burden and mental health problems associated with the disease. Diabetes-related distress (DRD) has distinct effects on self-care behaviours and disease control. Improving DRD in adults with T2DM could enhance psychological well-being, health-related quality of life, self-care abilities and disease control, also reducing depressive symptoms.

OBJECTIVES

To assess the effects of psychological interventions for diabetes-related distress in adults with T2DM.

SEARCH METHODS

We searched the Cochrane Library, MEDLINE, Embase, PsycINFO, CINAHL, BASE, WHO ICTRP Search Portal and ClinicalTrials.gov. The date of the last search was December 2014 for BASE and 21 September 2016 for all other databases.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) on the effects of psychological interventions for DRD in adults (18 years and older) with T2DM. We included trials if they compared different psychological interventions or compared a psychological intervention with usual care. Primary outcomes were DRD, health-related quality of life (HRQoL) and adverse events. Secondary outcomes were self-efficacy, glycosylated haemoglobin A1c (HbA1c), blood pressure, diabetes-related complications, all-cause mortality and socioeconomic effects.

DATA COLLECTION AND ANALYSIS

Two review authors independently identified publications for inclusion and extracted data. We classified interventions according to their focus on emotion, cognition or emotion-cognition. We performed random-effects meta-analyses to compute overall estimates.

MAIN RESULTS

We identified 30 RCTs with 9177 participants. Sixteen trials were parallel two-arm RCTs, and seven were three-arm parallel trials. There were also seven cluster-randomised trials: two had four arms, and the remaining five had two arms. The median duration of the intervention was six months (range 1 week to 24 months), and the median follow-up period was 12 months (range 0 to 12 months). The trials included a wide spectrum of interventions and were both individual- and group-based.A meta-analysis of all psychological interventions combined versus usual care showed no firm effect on DRD (standardised mean difference (SMD) -0.07; 95% CI -0.16 to 0.03; P = 0.17; 3315 participants; 12 trials; low-quality evidence), HRQoL (SMD 0.01; 95% CI -0.09 to 0.11; P = 0.87; 1932 participants; 5 trials; low-quality evidence), all-cause mortality (11 per 1000 versus 11 per 1000; risk ratio (RR) 1.01; 95% CI 0.17 to 6.03; P = 0.99; 1376 participants; 3 trials; low-quality evidence) or adverse events (17 per 1000 versus 41 per 1000; RR 2.40; 95% CI 0.78 to 7.39; P = 0.13; 438 participants; 3 trials; low-quality evidence). We saw small beneficial effects on self-efficacy and HbA1c at medium-term follow-up (6 to 12 months): on self-efficacy the SMD was 0.15 (95% CI 0.00 to 0.30; P = 0.05; 2675 participants; 6 trials; low-quality evidence) in favour of psychological interventions; on HbA1c there was a mean difference (MD) of -0.14% (95% CI -0.27 to 0.00; P = 0.05; 3165 participants; 11 trials; low-quality evidence) in favour of psychological interventions. Our included trials did not report diabetes-related complications or socioeconomic effects.Many trials were small and were at high risk of bias for incomplete outcome data as well as possible performance and detection biases in the subjective questionnaire-based outcomes assessment, and some appeared to be at risk of selective reporting. There are four trials awaiting further classification. These are parallel RCTs with cognition-focused and emotion-cognition focused interventions. There are another 18 ongoing trials, likely focusing on emotion-cognition or cognition, assessing interventions such as diabetes self-management support, telephone-based cognitive behavioural therapy, stress management and a web application for problem solving in diabetes management. Most of these trials have a community setting and are based in the USA.

AUTHORS' CONCLUSIONS

Low-quality evidence showed that none of the psychological interventions would improve DRD more than usual care. Low-quality evidence is available for improved self-efficacy and HbA1c after psychological interventions. This means that we are uncertain about the effects of psychological interventions on these outcomes. However, psychological interventions probably have no substantial adverse events compared to usual care. More high-quality research with emotion-focused programmes, in non-US and non-European settings and in low- and middle-income countries, is needed.

Development and Validation of a Novel Generic Health-related Quality of Life Instrument With 20 Items (HINT-20)

Objectives

Few attempts have been made to develop a generic health-related quality of life (HRQoL) instrument and to examine its validity and reliability in Korea. We aimed to do this in our present study.

Methods

After a literature review of existing generic HRQoL instruments, a focus group discussion, in-depth interviews, and expert consultations, we selected 30 tentative items for a new HRQoL measure. These items were evaluated by assessing their ceiling effects, difficulty, and redundancy in the first survey. To validate the HRQoL instrument that was developed, known-groups validity and convergent/discriminant validity were evaluated and its test-retest reliability was examined in the second survey.

Results

Of the 30 items originally assessed for the HRQoL instrument, four were excluded due to high ceiling effects and six were removed due to redundancy. We ultimately developed a HRQoL instrument with a reduced number of 20 items, known as the Health-related Quality of Life Instrument with 20 items (HINT-20), incorporating physical, mental, social, and positive health dimensions. The results of the HINT-20 for known-groups validity were poorer in women, the elderly, and those with a low income. For convergent/discriminant validity, the correlation coefficients of items (except vitality) in the physical health dimension with the physical component summary of the Short Form 36 version 2 (SF-36v2) were generally higher than the correlations of those items with the mental component summary of the SF-36v2, and vice versa. Regarding test-retest reliability, the intraclass correlation coefficient of the total HINT-20 score was 0.813 (p<0.001).

Conclusions

A novel generic HRQoL instrument, the HINT-20, was developed for the Korean general population and showed acceptable validity and reliability.

Positive Psychological Interventions for Patients with Type 2 Diabetes: Rationale, Theoretical Model, and Intervention Development

Most patients with type 2 diabetes (T2D) have suboptimal adherence to recommended diet, physical activity, and/or medication. Current approaches to improve health behaviors in T2D have been variably effective, and successful interventions are often complex and intensive. It is therefore vital to develop interventions that are simple, well-accepted, and applicable to a wide range of patients who suffer from T2D. One approach may be to boost positive psychological states, such as positive affect or optimism, as these constructs have been prospectively and independently linked to improvements in health behaviors. Positive psychology (PP) interventions, which utilize systematic exercises to increase optimism, well-being, and positive affect, consistently increase positive states and are easily delivered to patients with chronic illnesses. However, to our knowledge, PP interventions have not been formally tested in T2D. In this paper, we review a theoretical model for the use of PP interventions to target health behaviors in T2D, describe the structure and content of a PP intervention for T2D patients, and describe baseline data from a single-arm proof-of-concept (N = 15) intervention study in T2D patients with or without depression. We also discuss how PP interventions could be combined with motivational interviewing (MI) interventions to provide a blended psychological-behavioral approach.

Psychological aspects of diabetes care: Effecting behavioral change in patients

Patients with diabetes mellitus (DM) need psychological support throughout their life span from the time of diagnosis. The psychological make-up of the patients with DM play a central role in self-management behaviors. Without patient’s adherence to the effective therapies, there would be persistent sub-optimal control of diseases, increase diabetes-related complications, causing deterioration in quality of life, resulting in increased healthcare utilization and burden on healthcare systems. However, provision of psychosocial support is generally inadequate due to its challenging nature of needs and demands on the healthcare systems. This review article examines patient’s psychological aspects in general, elaborates in particular about emotion effects on health, and emotion in relation to other psychological domains such as cognition, self-regulation, self-efficacy and behavior. Some descriptions are also provided on willpower, resilience, illness perception and proactive coping in relating execution of new behaviors, coping with future-oriented thinking and influences of illness perception on health-related behaviors. These psychological aspects are further discussed in relation to DM and interventions for patients with DM. Equipped with the understanding of the pertinent nature of psychology in patients with DM; and knowing the links between the psychological disorders, inflammation and cardiovascular outcomes would hopefully encourages healthcare professionals in giving due attention to the psychological needs of patients with DM.

Personal accounts of the negative and adaptive psychosocial experiences of people with diabetes in the second Diabetes Attitudes, Wishes and Needs (DAWN2) study

OBJECTIVE

To identify the psychosocial experiences of diabetes, including negative accounts of diabetes and adaptive ways of coping from the perspective of the person with diabetes.

RESEARCH DESIGN AND METHODS

Participants were 8,596 adults (1,368 with type 1 diabetes and 7,228 with type 2 diabetes) in the second Diabetes Attitudes, Wishes and Needs (DAWN2) study. Qualitative data were responses to open-ended survey questions about successes, challenges, and wishes for improvement in living with diabetes and about impactful experiences. Emergent coding developed with multinational collaborators identified thematic content about psychosocial aspects. The κ measure of interrater reliability was 0.72.

RESULTS

Analysis identified two negative psychosocial themes: 1) anxiety/fear, worry about hypoglycemia and complications of diabetes, depression, and negative moods/hopelessness and 2) discrimination at work and public misunderstanding about diabetes. Two psychosocial themes demonstrated adaptive ways of coping with diabetes: 1) having a positive outlook and sense of resilience in the midst of having diabetes and 2) receiving psychosocial support through caring and compassionate family, friends, health care professionals, and other people with diabetes.

CONCLUSIONS

The personal accounts give insight into the psychosocial experiences and coping strategies of people with diabetes and can inform efforts to meet those needs and capitalize on strengths.

Relationships of diabetes-specific emotional distress, depression, anxiety, and overall well-being with HbA1c in adult persons with type 1 diabetes

OBJECTIVE

Emotional problems are common in adults with diabetes, and knowledge about how different indicators of emotional problems are related with glycemic control is required. The aim was to examine the relationships of diabetes-specific emotional distress, depression, anxiety, and overall well-being with glycosylated hemoglobin (HbA1c).

METHODS

Of the 319 adults with type 1 diabetes attending the endocrinology outpatient clinic at a university hospital in Norway, 235 (74%) completed the Diabetes Distress Scale, the Problem Areas in Diabetes Survey, the Hospital Anxiety and Depression Scale, and the World Health Organization-Five Well-Being Index. Blood samples were taken at the time of data collection to determine HbA1c. Regression analyses examined associations of diabetes-specific emotional distress, anxiety, depression, and overall well-being with HbA1c. The relationship between diabetes-specific emotional distress and HbA1c was tested for nonlinearity.

RESULTS

Diabetes-specific emotional distress was related to glycemic control (DDS total: unstandardized coefficient=0.038, P<.001; PAID total: coefficient=0.021, P=.007), but depression, anxiety, and overall well-being were not. On the DDS, only regimen-related distress was independently related to HbA1c (coefficient=0.056, P<.001). A difference of 0.5 standard deviation of baseline regimen distress is associated with a difference of 0.6 in HbA1c. No significant nonlinearity was detected in the relationship between diabetes-specific distress and HbA1c.

CONCLUSIONS

To stimulate adequate care strategies, health personnel should acknowledge depression and diabetes-specific emotional distress as different conditions in clinical consultations. Addressing diabetes-specific emotional distress, in particular regimen distress, in clinical consultation might improve glycemic control.

Association between extraversion personality and abnormal glucose regulation in young Korean women

Depression and psychological distress are known to be associated with diabetes development as well as the disease progression including glycemic control and chronic complication, but relationship of personality with diabetes is controversial. We examined whether personality trait and the presence of abnormal glucose regulation (AGR; diabetes and pre-diabetes) are associated in young women. A total of 1,617 young women aged 19-39 years without previously diagnosed diabetes were participated voluntarily. Personality trait was assessed by self-reported questionnaire using the five-factor model (neuroticism, extraversion, openness to experience, agreeableness and conscientiousness) consisting of five-point scale ranging from 'strongly disagreeable' to 'strongly agreeable.' Glucose tolerance status was assessed by standard 75-g oral glucose tolerance test. One hundred and eleven women were newly diagnosed with AGR (6.9 %). Among five factors, only extraversion trait was significantly associated with AGR. Multiple linear regression analysis showed significant negative association between extraversion trait and 2-h post-load glucose after adjustment for age, BMI, systolic blood pressure, triglycerides, HDL cholesterol and family history of diabetes (β = -0.16, P = 0.026). Multiple logistic regression showed extraversion trait having a significant association with the presence of AGR after adjustment for the same covariates (OR 0.97, 95 % CI 0.95-0.99, P = 0.011). The frequency of AGR was significantly increased according to the decrease in extraversion score (P for trend with exact test = 0.047). In conclusion, extraversion may be an important personality trait having a beneficial effect on decreasing the risk of AGR.

The association between resilience and diabetic neuropathy by socioeconomic position: cross-sectional findings from the KORA-Age study

We investigated whether older adults with diabetes mellitus and lower resilience have an increased risk of diabetic neuropathy as compared to older adults with higher resilience, and whether this association varies by socioeconomic position. In total, 3942 individuals took part in a health survey in Augsburg, Germany, in 2008-2010 (KORA-Age study). We found that among participants with low socioeconomic position, those with higher resilience had a lower probability of suffering from neuropathy as compared to participants with lower resilience (absolute risk reduction = 10%). Adjusted odds ratio with 95% confidence intervals for the outcome diabetic neuropathy also showed that lower resilience scores had an independent effect in increasing the risk of diabetic neuropathy among elderly individuals with a low socioeconomic position (odds ratio: 1.83; confidence interval: 1.09-3.08). Health-promoting strategies focussing on resilience should be further explored.

Effect of comorbid depression on quality of life in adults with Type 2 diabetes

This review outlines the effect of depression on quality of life (QoL) in patients with Type 2 diabetes mellitus (T2DM). The prevalence and medical, psychological and financial burden of T2DM in the USA are briefly discussed, similar to the findings related to patients living with T2DM and depression in terms of health-related QoL. Recommendations for future research include studying mechanisms by which depression affects the QoL of T2DM patients, outlining effects of positive emotions on managing consequences of distress and depression in these patients, and developing interventions to address both depression and diabetes that minimize the treatment burden and costs for patients.

Affective symptoms and change in diabetes self-efficacy and glycaemic control

AIMS

To examine the role of baseline depression, anxiety and stress symptoms on post-intervention diabetes self-efficacy and glycaemic control (HbA(1c)).

METHODS

The current study analysed data from patients (n = 85) with treated but uncontrolled Type 2 diabetes who participated in a comparative effectiveness study of two diabetes self-management interventions. Hierarchical linear regression was used to examine the relationships between baseline affective symptoms and post-intervention diabetes self-efficacy and the moderating effects of baseline affective symptoms on the relationship between changes in diabetes self-efficacy and post-intervention HbA(1c).

RESULTS

Baseline depression was inversely associated with post-intervention diabetes self-efficacy (P = 0.0001) after adjusting for baseline characteristics including diabetes self-efficacy. In contrast, normal-mild levels of stress were associated with higher post-intervention diabetes self-efficacy (P = 0.04). Anxiety and stress symptoms significantly and independently moderated the relationship between changes in diabetes self-efficacy and post-intervention HbA(1c) (P = 0.02 and P = 0.03, respectively). Further evaluation of these interactions demonstrated that changes in diabetes self-efficacy were associated with lower post-intervention HbA(1c), but only among those with higher baseline affective symptoms.

CONCLUSIONS

We found a moderating effect across affective symptoms on the relationship between diabetes self-efficacy changes and post-intervention HbA1c in the context of a self-management intervention. Results suggest that patients with poorly controlled diabetes who have higher levels of depression, anxiety and stress symptoms may derive greater benefits from self-management interventions known to improve diabetes self-efficacy.

Improvement of diabetic or obese patients' erythrocyte deformability by the program of the brain-oriented obesity control system (BOOCS)

Diabetes is characterized by absolute or relative insulin deficiency complicated with microangiopathy, whereas obesity stems from insulin resistance. A psychosomatic approach to obesity and diabetes has been highlighted, including the brain-oriented obesity control system (BOOCS). Impaired deformability of erythrocytes in obese or diabetic patients is closely linked to disturbed microcirculation, and improvement of abnormal erythrocyte rheology is a prerequisite for the prevention and treatment of microangiopathy. Therefore, erythrocyte filterability, whole cell deformability defined as flow rate of erythrocyte suspension relative to that of saline, was assessed by the nickel-mesh-filtration technique. Subjects included healthy controls (group A, n = 14), diabetic, non-obese participants (group B, n = 29), and non-diabetic, obese participants (group C, n = 32) in the 6-month BOOCS program, and most patients in groups B and C (86.9 %) completed this program. Baseline mean erythrocyte filterabilities were 89.4 ± 1.7 % in group A, 82.8 ± 5.2 % in group B, and 84.1 ± 5.6 % in group C, showing significant intergroup differences (p < 0.001). This program significantly improved (p < 0.001) the impaired erythrocyte filterability in groups B (87.9 ± 4.4 %) and C (88.5 ± 3.7 %). Declines in HbA1c (p = 0.387) and body mass index (p = 0.479) were not correlated to this improvement. These findings indicate that the mechanisms of BOOCS-induced improvement of diabetic or obese patients' erythrocyte deformability are multifactorial, and that the BOOCS program for these patients is a holistic, cost-effective, and highly compliant approach possibly ameliorating microcirculation.
