Feasibility and Acceptability of a Positive Psychological Intervention for Patients With Type 2 Diabetes

Positive Psychology Interventions for Improving Self-management Behaviors in Patients with Type 1 and Type 2 Diabetes: a Narrative Review of Current Evidence

PURPOSE OF REVIEW

Interests have been emerging in using positive psychology interventions (PPIs) to improve diabetes self-management (DSM) behaviors (e.g., blood glucose monitoring, physical activity). To explore the impact of those interventions on DSM behaviors, we summarized the evidence of PPIs on self-management behaviors among both type 1 diabetes (T1D) and type 2 diabetes (T2D) patients between 2012 and 2022.

RECENT FINDINGS

Among the eight studies identified, different study designs and types of PPIs were apparent. Typical PPIs (e.g., activities enhancing positive affect/gratitude/self-affirmation/optimism) were usually applied to T1D patients (N = 5); PPIs were usually combined with motivational interviewing for T2D patients (N = 3). Contrary to expectations, PPIs did not consistently demonstrate positive effects on self-management behaviors' change regardless of the types of diabetes patients, compared to the control groups. Improvements in diabetes patients' self-management behaviors from PPIs are still unclear. Future studies should more rigorously evaluate and identify the active ingredients of PPIs for behavioral changes among diabetes patients.

Technology-Supported Integrated Care Innovations to Support Diabetes and Mental Health Care: Scoping Review

BACKGROUND

For individuals living with diabetes and its psychosocial comorbidities (eg, depression, anxiety, and distress), there remains limited access to interprofessional, integrated care that includes mental health support, education, and follow-up. Health technology, broadly defined as the application of organized knowledge or skill as software, devices, and systems to solve health problems and improve quality of life, is emerging as a means of addressing these gaps. There is thus a need to understand how such technologies are being used to support, educate, and help individuals living with co-occurring diabetes and mental health distress or disorder.

OBJECTIVE

The purpose of this scoping review was to (1) describe the literature on technology-enabled integrated interventions for diabetes and mental health; (2) apply frameworks from the Mental Health Commission of Canada and World Health Organization to elucidate the components, type, processes, and users of technology-enabled integrated interventions for diabetes and mental health; and (3) map the level of integration of interventions for diabetes and mental health.

METHODS

We searched 6 databases from inception to February 2022 for English-language, peer-reviewed studies of any design or type that used technology to actively support both diabetes and any mental health distress or disorder in succession or concurrently among people with diabetes (type 1 diabetes, type 2 diabetes, and gestational diabetes). Reviewers screened citations and extracted data including study characteristics and details about the technology and integration used.

RESULTS

We included 24 studies described in 38 publications. These studies were conducted in a range of settings and sites of care including both web-based and in-person settings. Studies were mostly website-based (n=13) and used technology for wellness and prevention (n=16) and intervention and treatment (n=15). The primary users of these technologies were clients and health care providers. All the included intervention studies (n=20) used technology for clinical integration, but only 7 studies also used the technology for professional integration.

CONCLUSIONS

The findings of this scoping review suggest that there is a growing body of literature on integrated care for diabetes and mental health enabled by technology. However, gaps still exist with how to best equip health care professionals with the knowledge and skills to offer integrated care. Future research is needed to continue to explore the purpose, level, and breadth of technology-enabled integration to facilitate an approach to overcome or address care fragmentation for diabetes and mental health and to understand how health technology can further drive the scale-up of innovative integrated interventions.

Community-Based Evaluation of the Associations Between Well-Being and Cardiovascular Disease Risk

Background Although the effects of psychological health and optimism have been extensively investigated, data from community-based cohorts assessing the association between psychological health and cardiovascular disease risk factors are sparse, and the concurrent relationship between subjective well-being and cardiovascular health has not been studied. Methods and Results The current cross-sectional study examined the association between well-being and cardiovascular risk factors among 719 individuals living in a middle- to low-income neighborhood. After adjusting for age, sex, race, body mass index, education, smoking status, and exercise status, we found that higher levels of well-being were significantly associated with lower odds of dyslipidemia (odds ratio [OR], 0.7 [95% CI, 0.55-0.85]) and hypertension (OR, 0.8 [95% CI, 0.63-0.92]). Greater well-being was also significantly associated with lower triglyceride levels (mean difference [Mdiff], 7.6 [-14.31 to -0.78]), very low-density lipoprotein (Mdiff, 0.9 [-1.71 to -0.16]), total cholesterol to high-density lipoprotein ratio (Mdiff, 3.9 [-6.07 to -1.73]), higher high-density lipoprotein levels (Mdiff, 1.6 [0.46-2.75]), and lower Framingham Risk Scores (Mdiff, -7.1% [-10.84% to -3.16%]). Well-being also moderated the association between age and arterial stiffness. The strongest association between arterial stiffness and age was found for those with the lowest well-being scores; there was no association between age and arterial stiffness at high levels of well-being. Conclusions In a community-based cohort, individuals reporting higher levels of well-being have lower odds of hypertension and dyslipidemia as well as lower rates of age-dependent increase in vascular stiffness.

Introducing the Postpartum Toolkit: An Examination of the Feasibility, Acceptability and Pilot Efficacy of an Online Clinical Tool to Enhance Postpartum Functioning and Emotional Wellbeing

During the postpartum period, a birth parent's level of functioning (ability to perform the activities and roles required to maintain wellbeing) is critical in determining the health of parents and their infants. However, existing approaches to support postpartum parents are insufficient, especially in the United States, and these individuals face barriers to care. The utilization of internet-based intervention may be an effective solution allowing access to resources for this population. In this study, we developed a patient-centered online tool to bolster postpartum functioning, and collected data on the feasibility, acceptability, and initial impact of this tool on functioning and emotional wellbeing. Data collection took place between February and June 2021 from a sample of 124 individuals who were within the first ten months postpartum and living in the US. Results suggest that the tool is acceptable, though there are barriers to feasibility of use. Additionally, pilot-efficacy data suggest that this tool may be effective in improving postpartum emotional wellbeing, though further controlled testing is warranted. A future iteration of the tool that incorporates participant feedback to improve feasibility of use could prove an effective means of delivering support to an at-risk population.

A positive psychology-motivational interviewing program to promote physical activity in type 2 diabetes: The BEHOLD-16 pilot randomized trial

BACKGROUND

The majority of persons with type 2 diabetes (T2D) do not meet recommended levels of physical activity, despite clear links between physical activity and superior medical outcomes in this population. The objective of this trial was to assess the feasibility and impact of a novel 16-week combined positive psychology-motivational interviewing (PP-MI) program to promote physical activity among inactive persons with T2D.

METHODS

This pilot randomized trial compared the 16-week, phone-delivered PP-MI intervention to an attention-matched diabetes counseling condition among 70 persons with T2D and low levels of baseline moderate to vigorous physical activity (MVPA; <150 min/week). The primary study outcomes were feasibility (assessed via rates of session completion) and acceptability (assessed via mean participant ratings [0-10] of the ease and utility of weekly sessions). Key secondary outcomes included between-group differences in improvement in positive affect, other psychological outcomes, and accelerometer-measured physical activity, assessed using mixed effects regression models, at 16 and 24 weeks.

RESULTS

Participants completed a mean 11.0 (SD 4.4; 79%) of 14 PP-MI phone sessions, and composite mean ratings of ease/utility were 8.6/10, above our a priori benchmarks for feasibility/acceptability (70% session completion; 7.0/10 mean ratings). PP-MI participants had small to medium effect size (ES) difference improvements in MVPA (ES difference = 0.34) and steps/day (ES difference = 0.76) at 16 weeks, with sustained but smaller effects at 24 weeks (ES difference = 0.22-0.33).

CONCLUSIONS

Next-step studies of this PP-MI program in T2D patients can more rigorously explore the intervention's effects on physical activity and clinical outcomes.

A spotlight on the surfacing of self-management of employees with diabetes seen by professional nurses in selected occupational health clinics in Cape Town

Background

Diabetes is considered one of the largest global health challenges of this century and one of the top 10 causes of death across the world. Studies indicate an increased economic burden in relation to diabetes, not only on government revenue but also within private industries. Exploring the perceptions of employees with diabetes mellitus as related to their self-management practices could assist in encouraging behaviours that are associated with positive management outcomes.

Aim

The purpose of this study was to explore and describe the perceptions of employees with diabetes mellitus, seen by professional nurses in selected occupational health clinics, about the self-management of their disease.

Methods

A qualitative, exploratory, descriptive contextual design was followed through 17 individual interviews with 17 employees working in various industries in Cape Town, using a semi-structured interview schedule. Open coding of the data followed, and four themes emerged. Measures to ensure trustworthiness were also adhered to in the study, and approval for the study was granted.

Results

The study findings gave insight into the manner in which employees perceived their behaviour changes in terms of their self-management practices. Various emotions were expressed by employees relating to the disease as well as the lifestyle adaptations required for self-management thereof. Employees noted that knowledge acquisition and greater understanding of the motivators for lifestyle changes could improve aspects of their day-to-day living as well as the disease outcomes.

Conclusion

Employees expressed an awareness of the changes and lifestyle adaptations needed but found aspects thereof to be an ongoing challenge. The areas of challenge varied amongst employees. A consciousness of the possible consequences of poor self-management practices and self-modification behavior to address these was observed.

Exploring the feasibility and impact of positive psychology-motivational interviewing interventions to promote positive affect and physical activity in type 2 diabetes: design and methods from the BEHOLD-8 and BEHOLD-16 clinical trials

BACKGROUND

Physical activity among those with type 2 diabetes (T2D) is independently associated with superior medical outcomes, but existing behavioral interventions have not led to widespread increases in activity in this population. A remotely delivered intervention that targets well-being constructs associated with greater activity and assists in the creation of specific physical activity goals has the potential to improve activity and outcomes in T2D.

OBJECTIVE

To outline the rationale and methods of two studies designed to assess the impact and optimal duration of a combined positive psychology-motivational interviewing (PP-MI) intervention for inactive persons with T2D.

METHODS

We conducted trials studying 8-week (BEHOLD-8;) and 16-week (BEHOLD-16;) phone-delivered interventions, compared to attention-matched control conditions. In a two-step randomization design, participants were allocated randomly first to study (BEHOLD-8 or BEHOLD-16), then to study condition within study. The primary aims in both trials were feasibility (rates of session completion) and acceptability (participant session ratings), with additional aims examining intervention effects on accelerometer-measured physical activity, psychological measures, and health-related metrics (e.g. vital signs). Main analyses, currently being conducted, will utilize mixed effects models between study conditions, and secondary analyses will utilize the same models to compare the 8- and 16-week PP-MI interventions on feasibility and impact.

RESULTS

Enrollment and data collection have been completed for both trials (BEHOLD-8: N = 60; BEHOLD-16: N = 70), and data analysis is ongoing to assess feasibility and acceptability within study, as well as the relative feasibility and acceptability of the PP-MI interventions across the two studies. We will also explore impact on clinical outcomes between groups.

CONCLUSIONS

This design will address how intervention content (i.e. PP elements vs. no PP elements) and intervention duration (8 weeks vs. 16 weeks) affect feasibility, acceptability, and impact, allowing intervention optimization before a next-step larger clinical trial.

An At-home Positive Psychology Intervention for Individuals with Multiple Sclerosis: A Phase 1 Randomized Controlled Trial

Background

Positive psychology (PP) uses targeted activities to increase the frequency and intensity of positive feelings and may improve overall well-being in medically ill populations. In this phase 1 randomized controlled trial, we examined the feasibility, acceptability, and potential impact of a 5-week, telephone-delivered PP intervention for individuals with multiple sclerosis (MS).

Methods

Participants were randomized 1:1 to a 5-week at-home PP intervention or a waitlist control condition. Participants engaged in weekly telephone calls with a study trainer and completed one PP exercise, such as recalling a past success, each week. Feasibility was determined by the number of sessions completed, and acceptability was assessed by weekly postexercise participant ratings of ease and utility. Efficacy was explored by examining between-group differences in changes from baseline on psychological variables, health-related quality of life, and self-reported functional activities at 5 and 10 weeks.

Results

Of 30 patients enrolled in the study, 28 (93%) completed all exercises. Ease scores ranged from 7.7 to 8.7 of 10 and utility scores ranged from 8.2 to 8.7 of 10. The PP intervention was associated with significantly greater increases (P < .05) in positive affect, optimism, state and trait anxiety, general health, and resilience in the intervention group versus the control group. Approximately half of the PP participants maintained at least 50% of the improvement at 10 weeks.

Conclusions

This 5-week, telephone-based PP intervention was feasible and acceptable to individuals with MS. Larger randomized controlled trials are warranted to further investigate the utility of this intervention to improve well-being and other health outcomes in MS.

Implementation of a Multi-Component School Lunch Environmental Change Intervention to Improve Child Fruit and Vegetable Intake: A Mixed-Methods Study

Nudge interventions are widely used to promote health in schools, yet implementation metrics are seldom used to understand intervention outcomes. A multi-component intervention consisting of cafeteria decorations, creative names, social norming taste tests, and flavor station components was implemented in three rural elementary school cafeterias by school nutrition services (SNS) and extension staff. Selection and consumption of fruits and vegetables at lunch were measured through monthly plate waste assessments over eight months (n = 1255 trays). Interviews were conducted with SNS staff (n = 3) upon completion of the intervention to assess implementation outcomes using validated acceptability and feasibility metrics. Consumption findings were generally inconsistent across schools and time points, yet fruit consumption increased at School 1 (p < 0.05) during the taste test and flavor station intervention months and School 2 (p < 0.001) during the creative names intervention months compared to baseline. Odds of selecting a vegetable at School 3 were three times higher than baseline during the taste test intervention months (odds ratio (OR), 3.0; 95% confidence interval (CI), 1.3–6.5). Cafeteria decorations and taste tests had higher reported implementation metrics for acceptability and feasibility than other interventions. Thematic analysis underscored the facilitating role of extension support, as well as systems factors, which served as facilitators and barriers across schools and interventions. These findings suggest that nudge interventions are a promising strategy to improve vegetable selection and fruit consumption in school meal programs.

Variability in sleep disturbance, physical activity and quality of life by level of depressive symptoms in women with Type 2 diabetes

AIMS

To examine (1) the prevalence of depressive symptoms in women with Type 2 diabetes, (2) the associations between depressive symptoms and the following dependent variables: sleep disturbance; physical activity; physical health-related; and global quality of life, and (3) the potential moderating effects of antidepressants and optimism on the relationship between depressive symptoms and dependent variables.

METHODS

Participants in the Women's Health Initiative who had Type 2 diabetes and data on depressive symptoms (N=8895) were included in the analyses. In multivariable linear regression models controlling for sociodemographic, medical and psychosocial covariates, we examined the main effect of depressive symptoms, as well as the interactions between depressive symptoms and antidepressant use, and between depressive symptoms and optimism, on sleep disturbance, physical activity, physical health-related quality of life; and global quality of life.

RESULTS

In all, 16% of women with Type 2 diabetes reported elevated depressive symptoms. In multivariable analyses, women with depressive symptoms had greater sleep disturbance (P<0.0001) and lower global quality of life (P<.0001). We found evidence of significant statistical interaction in the models for quality-of-life outcomes: the increased risk of poor physical health-related quality of life associated with antidepressant use was stronger in women without vs with depressive symptoms, and the association between greater optimism and higher global quality of life was stronger in women with vs without depressive symptoms.

CONCLUSIONS

To improve health behaviours and quality of life in women with Type 2 diabetes, sociodemographic and medical characteristics may identify at-risk populations, while psychosocial factors including depression and optimism may be important targets for non-pharmacological intervention.

A positive psychology-motivational interviewing intervention for patients with type 2 diabetes: Proof-of-concept trial

OBJECTIVE

Eighteen million Americans with type 2 diabetes (T2D) do not follow recommended guidelines for physical activity. Motivational interviewing (MI) has had modest effects on activity and related behaviors in T2D. Positive psychological attributes (e.g., optimism) are associated with superior medical outcomes in T2D, and positive psychology (PP) interventions promote such attributes. There had been no study in T2D of a combined PP-MI intervention to promote well-being and health behavior adherence. We developed a novel, telephone-delivered, 16-week PP-MI intervention and explored its feasibility and impact in T2D patients in a single-arm, proof-of-concept trial.

METHOD

Participants completed PP-based exercises and MI-based physical activity goal-setting activities and reviewed these activities weekly with a study trainer for 16 weeks. Feasibility and acceptability were assessed via exercise completion rates and post-exercise ratings of ease/utility (0-10 scales). Impact was explored by examining changes in physical activity (via accelerometers and self-report), other health behaviors, psychological measures, and medical outcomes (e.g., hemoglobin A1c (A1C)) from baseline to 16 weeks, using paired t tests.

RESULTS

Twelve participants enrolled, and 10 provided follow-up data. Seventy-eight percent of PP-MI activities were completed, and participants rated the PP-MI content and sessions as easy (mean = 8.2/10, standard deviation (SD) = 1.9) and useful (mean = 9.1/10, SD = 1.5). PP-MI was associated with improved adherence to health behaviors and overall self-care, variable effects on accelerometer-measured activity and psychological outcomes, and modest beneficial effects on body mass index and A1C.

CONCLUSION

Further testing of this intervention is warranted in a larger, controlled trial to assess its effects on important health outcomes.

Well-being interventions for individuals with diabetes: A systematic review

In patients with diabetes, psychological well-being constructs (e.g., optimism, positive affect) have been associated with superior medical outcomes, including better glucose control and lower mortality rates. Well-being interventions may be well-suited to individuals with diabetes, as they are simple to deliver, broadly applicable across a range of psychological distress, and may help increase self-efficacy and motivation for diabetes self-care. This systematic review, completed using PRISMA guidelines, examined peer-reviewed studies indexed in PubMed, PsycINFO, and/or Scopus between database inception and October 2017 that investigated the effects of well-being interventions (e.g., positive psychology interventions, mindfulness-based interventions, resilience-based interventions) on psychological and physical health outcomes in individuals with Type 1 or Type 2 diabetes. The search yielded 34 articles (N = 1635 participants), with substantial variability in intervention type, measures used, and outcomes studied; the majority found the intervention to provide benefit. Overall, results indicate that a range of well-being interventions appear to have promise in improving health outcomes in this population, but the literature does not yet provide definitive data about which specific interventions are most effective. The variability in interventions and outcomes points to a need for further rigorous, controlled, and well-powered studies of specific interventions, with well-accepted, clinically relevant outcome measures.

Longitudinal associations between psychological well-being and the consumption of fruits and vegetables

BACKGROUND

Psychological well-being is associated with longevity and reduced risk of disease, but possible mechanisms are understudied. Health behaviors like eating fruits and vegetables may link psychological well-being with better health; however, most evidence is cross-sectional.

PURPOSE

This study investigated psychological well-being's longitudinal association with fruit and vegetable consumption across as many as 7 years.

METHOD

Participants were 6,565 older adults from the English Longitudinal Study of Ageing, which includes men and women aged 50 years or older. Psychological well-being was assessed with 17 items from the Control, Autonomy, Satisfaction, Pleasure Scale. Fruit and vegetable consumption was initially assessed during 2006-2007 and then approximately every 2 years through 2012-2013. Covariates included sociodemographic factors, health status, and other health behaviors.

RESULTS

Mixed linear models showed that higher baseline levels of psychological well-being were associated with more fruit and vegetable consumption at baseline (β = 0.05, 95% confidence interval [CI] [0.02, 0.08]) and that fruit and vegetable consumption declined across time (β = -0.01, 95% CI [-0.02, -0.004]). Psychological well-being interacted significantly with time such that individuals with higher baseline psychological well-being had slower declines in fruit and vegetable consumption (β = 0.01, 95% CI [0.01, 0.02]). Among individuals who initially met recommendations to consume 5 or more servings of fruits and vegetables (N = 1,719), higher baseline psychological well-being was associated with 11% reduced risk of falling below recommended levels during follow-up (hazard ratio = 0.89, 95% CI [0.83, 0.95]).

CONCLUSIONS

Findings suggest that psychological well-being may be a precursor to healthy behaviors such as eating a diet rich in fruits and vegetables. (PsycINFO Database Record

A Positive Psychology Intervention to Promote Health Behaviors in Heart Failure: A Proof-of-Concept Trial

Patients with heart failure (HF) frequently struggle to adhere to health behaviors, and psychological factors may contribute to nonadherence. We examined the feasibility and acceptability of a 10-week, positive psychology (PP)-based intervention to promote health behavior adherence in patients (N = 10) with mild to moderate HF and suboptimal health behavior adherence. Participants engaged in weekly phone sessions, completed PP exercises (e.g., writing a gratitude letter, using a personal strength), and set goals related to diet, medication adherence, and physical activity. Feasibility was assessed by the number of sessions completed, and acceptability by participant ratings of ease and utility. Preliminary efficacy was measured by changes in psychological and adherence outcomes. The intervention was feasible (87% of exercises completed) and acceptable. Furthermore, in exploratory analyses, the intervention was associated with improvements in psychological and health behavior adherence outcomes. Larger, randomized trials are needed to further investigate the utility of this intervention.

Positive Psychological Well-Being and Cardiovascular Disease: JACC Health Promotion Series

Facets of positive psychological well-being, such as optimism, have been identified as positive health assets because they are prospectively associated with the 7 metrics of cardiovascular health (CVH) and improved outcomes related to cardiovascular disease. Connections between psychological well-being and cardiovascular conditions may be mediated through biological, behavioral, and psychosocial pathways. Individual-level interventions, such as mindfulness-based programs and positive psychological interventions, have shown promise for modifying psychological well-being. Further, workplaces are using well-being-focused interventions to promote employee CVH, and these interventions represent a potential model for expanding psychological well-being programs to communities and societies. Given the relevance of psychological well-being to promoting CVH, this review outlines clinical recommendations to assess and promote well-being in encounters with patients. Finally, a research agenda is proposed. Additional prospective observational studies are needed to understand mechanisms underlying the connection between psychological well-being and cardiovascular outcomes. Moreover, rigorous intervention trials are needed to assess whether psychological well-being-promoting programs can improve cardiovascular outcomes.

Effect of a Positive Psychological Intervention on Pain and Functional Difficulty Among Adults With Osteoarthritis: A Randomized Clinical Trial

IMPORTANCE

Positive psychological interventions for improving health have received increasing attention recently. Evidence on the impact of such interventions on pain, and racial disparities in pain, is limited.

OBJECTIVE

To assess the effects of a positive psychological intervention on pain and functional difficulty in veterans with knee osteoarthritis.

DESIGN, SETTING, AND PARTICIPANTS

The Staying Positive With Arthritis Study is a large, double-blinded randomized clinical trial powered to detect race differences in self-reported pain in response to a positive psychological intervention compared with a neutral control intervention. Data were collected from 2 urban Veterans Affairs medical centers. Participants included non-Hispanic white and non-Hispanic African American patients aged 50 years or older with a diagnosis of osteoarthritis. Mailings were sent to 5111 patients meeting these criteria, of whom 839 were fully screened, 488 were eligible, and 360 were randomized. Enrollment lasted from July 8, 2015, to February 1, 2017, with follow-up through September 6, 2017.

INTERVENTIONS

The intervention comprised a 6-week series of evidence-based activities to build positive psychological skills (eg, gratitude and kindness). The control program comprised similarly structured neutral activities. Programs were delivered via workbook and weekly telephone calls with interventionists.

MAIN OUTCOMES AND MEASURES

The primary outcomes were self-reported pain and functional difficulty measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC; range 0-100). Secondary outcomes included affect balance and life satisfaction.

RESULTS

The sample included 180 non-Hispanic white patients and 180 non-Hispanic African American patients (mean [SD] age, 64.2 [8.8] years; 76.4% were male). Mean (SD) baseline scores for WOMAC pain and functional difficulty were 48.8 (17.6) and 46.8 (18.1), respectively. Although both decreased significantly over time (pain: χ23 = 49.50, P < .001; functional difficulty: χ23 = 22.11, P < .001), differences were small and did not vary by treatment group or race. Exploratory analyses suggested that the intervention had counterintuitive effects on secondary outcomes.

CONCLUSIONS AND RELEVANCE

The results of this randomized clinical trial do not support the use of positive psychological interventions as a stand-alone treatment for pain among white or African American veterans with knee osteoarthritis. Adaptations are needed to identify intervention components that resonate with this population, and the additive effect of incorporating positive psychological interventions into more comprehensive pain treatment regimens should be considered.

Adherence to dietary recommendations in diabetes mellitus: disease acceptance as a potential mediator

BACKGROUND

Adherence by diabetic patients to dietary recommendations is important for effective therapy. Considering patients' expectations in case of diet is significant in this regard. The aim of this paper was to analyze the relationship between selected independent variables (eg, regular blood glucose testing) and patients' adherence to dietary recommendations, bearing in mind that the degree of disease acceptance might play a mediation role.

SUBJECTS AND METHODS

A cross-sectional study was conducted in 91 patients treated for type 2 diabetes mellitus in a public medical facility. Paper-and-pencil interviewing was administered ahead of the planned visit with a diabetes specialist. Two measures were applied in the study: the Acceptance and Action Diabetes Questionnaire and the Patient Diet Adherence in Diabetes Scale. Additionally, data related to sociodemographic characteristics, lifestyle-related factors, and the course of the disease (management, incidence of complications, and dietician's supervision) were also collected. The regression method was used in the analysis, and Cohen's methodology was used to estimate partial mediation. Significance of the mediation effect was assessed by the Goodman test. P-values of <0.05 were considered statistically significant.

RESULTS

Patients' non-adherence to dietary recommendations was related to a low level of disease acceptance (standardized regression coefficient =-0.266; P=0.010). Moreover, failure to perform regular blood glucose testing was associated with a lack of disease acceptance (standardized regression coefficient =-0.455; P=0.000). However, the lack of regular blood glucose testing and low level of acceptance had only partially negative impacts on adherence to dietary recommendations (Goodman mediation test, Z=1.939; P=0.054). This dependence was not seen in patients treated with diet and concomitant oral medicines and/or insulin therapy.

CONCLUSION

Effective dietary education should include activities promoting a more positive attitude toward the disease. This may be obtained by individual counseling, respecting the patient's needs, and focus on regular blood glucose testing.

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.

Testing a Positive Psychological Intervention for Osteoarthritis

OBJECTIVE

Osteoarthritis is a leading cause of disability for which there is no cure. Psychosocial-oriented treatments are underexplored. We developed and tested an intervention to build positive psychological skills (e.g., gratitude) to reduce osteoarthritis symptom severity, including pain and functioning, and to improve psychosocial well-being in patients with knee or hip osteoarthritis.

DESIGN

Two-arm randomized design with six-month follow-up.

SETTING

An academic Veterans Affairs Medical Center.

SUBJECTS

Patients aged 50 years or older with knee or hip osteoarthritis and pain ratings of 4 or higher.

METHODS

Patients (N = 42) were randomized to a six-week program containing positive skill-building activities or neutral control activities tailored to the patient population. Adherence was assessed by telephone each week. We assessed osteoarthritis symptom severity (WOMAC Osteoarthritis Index) and measures of well-being (positive affect, negative affect, and life satisfaction) at baseline and by telephone one, three, and six months after the program ended. We used linear mixed models to examine changes over time.

RESULTS

The majority (64%) of patients completed more than 80% of their weekly activities. Patients in the positive (vs neutral) program reported significantly more improvement over time in osteoarthritis symptom severity (P = 0.02, Cohen's d = 0.86), negative affect (P = 0.03, Cohen's d = 0.50), and life satisfaction (P = 0.02, Cohen's d = 0.36).

CONCLUSIONS

The study successfully engaged patients with knee or hip osteoarthritis in a six-week intervention to build positive psychological skills. Improving osteoarthritis symptom severity and measures of psychosocial well-being, the intervention shows promise as a tool for chronic pain management.

Rationale and design of the Staying Positive with Arthritis (SPA) Study: A randomized controlled trial testing the impact of a positive psychology intervention on racial disparities in pain

Knee osteoarthritis is a painful, disabling condition that disproportionately affects African Americans. Existing arthritis treatments yield small to moderate improvements in pain and have not been effective at reducing racial disparities in the management of pain. The biopsychosocial model of pain and evidence from the positive psychology literature suggest that increasing positive psychological skills (e.g., gratitude, kindness) could improve pain and functioning and reduce disparities in osteoarthritis pain management. Activities to cultivate positive psychological skills have been developed and validated; however, they have not been tested in patients with osteoarthritis, their effects on racial differences in health outcomes have not been examined, and evidence of their effects on health outcomes in patients with other chronic illnesses is of limited quality. In this article we describe the rationale and design of Staying Positive with Arthritis (SPA) study, a randomized controlled trial in which 180 African American and 180 White primary care patients with chronic pain from knee osteoarthritis will be randomized to a 6-week program of either positive skill-building activities or neutral control activities. The primary outcomes will be self-reported pain and functioning as measured by the WOMAC Osteoarthritis Index. We will assess these primary outcomes and potential, exploratory psychosocial mediating variables at an in-person baseline visit and by telephone at 1, 3, and 6months following completion of the assigned program. If effective, the SPA program would be a novel, theoretically-informed psychosocial intervention to improve quality and equity of care in the management of chronic pain from osteoarthritis.

Disease activity, resilience and health-related quality of life in Chinese patients with rheumatoid arthritis: a multi-center, cross-sectional study

Background

Positive psychological constructs that can moderate or mediate the negative impact of disease activity on health-related quality of life (HRQOL) in patients with rheumatoid arthritis (RA) have not been explored widely. This study aimed to assess the associations of disease activity, resilience with HRQOL and the moderating and mediating roles of resilience among Chinese RA patients.

Methods

A multi-center, cross-sectional study was conducted in RA inpatients in northeast of China. A total 298 subjects completed the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) and Ego-Resiliency Scale (ERS) to measure HRQOL and resilience. For the SF-36, physical function, physical role limitation, bodily pain and general health perception are gathered into physical component summary (PCS), while vitality, social functioning, emotional role limitation and mental health are gathered into mental component summary (MCS). Disease activity was evaluated by the Disease Activity Score 28-C-reactive protein (DAS28-CRP). Hierarchical regression analysis was applied to examine the associations of disease activity, resilience and the disease activity*resilience interaction with PCS and MCS, respectively. Asymptotic and resampling strategies were utilized to examine the mediating role of resilience.

Results

The mean scores of PCS and MCS were 40.67 and 59.14, respectively. Disease activity was negatively associated with both PCS and MCS, and resilience was only positively associated with MCS. The disease activity*resilience interaction term were significantly associated with MCS (β = 0.144, P = 0.003). The associations between disease activity and MCS were gradually reduced in low (1 SD below the mean, β = −0.369, P < 0.001), mean (β = −0.218, P < 0.001) and high (1 SD above the mean, β = −0.068, P = 0.369) groups of resilience. Resilience acted as a partial mediator in the disease activity-MCS association (effect size was −0.085, BCa 95% CI: −0.159, −0.028).

Conclusions

Disease activity was negatively associated with both physical and mental HRQOL, and resilience was only positively associated with mental HRQOL. Resilience could attenuate and mediate the association between disease activity and mental HRQOL. In addition to controlling disease activity, targeted intervention strategies designed for resilience should be strengthened to improve the HRQOL of this population.
