Association of Resilience and Social Networks with Pain Outcomes Among Older Adults

Repeated social defeat stress differently affects arthritis-associated hypersensitivity in male and female mice

Chronic stress enhances the risk of neuropsychiatric disorders and contributes to the aggravation and chronicity of pain. The development of stress-associated diseases, including pain, is affected by individual vulnerability or resilience to stress, although the mechanisms remain elusive. We used the repeated social defeat stress model promoting susceptible and resilient phenotypes in male and female mice and induced knee mono-arthritis to investigate the impact of stress vulnerability on pain and immune system regulation. We analyzed different pain-related behaviors, measured blood cytokine and immune cell levels, and performed histological analyses at the knee joints and pain/stress-related brain areas. Stress susceptible male and female mice showed prolonged arthritis-associated hypersensitivity. Interestingly, hypersensitivity was exacerbated in male but not female mice. In males, stress promoted transiently increased neutrophils and Ly6Chigh monocytes, lasting longer in susceptible than resilient mice. While resilient male mice displayed persistently increased levels of the anti-inflammatory interleukin (IL)-10, susceptible mice showed increased levels of the pro-inflammatory IL-6 at the early- and IL-12 at the late arthritis stage. Although joint inflammation levels were comparable among groups, macrophage and neutrophil infiltration was higher in the synovium of susceptible mice. Notably, only susceptible male mice, but not females, presented microgliosis and monocyte infiltration in the prefrontal cortex at the late arthritis stage. Blood Ly6Chigh monocyte depletion during the early inflammatory phase abrogated late-stage hypersensitivity and the associated histological alterations in susceptible male mice. Thus, recruitment of blood Ly6Chigh monocytes during the early arthritis phase might be a key factor mediating the persistence of arthritis pain in susceptible male mice. Alternative neuro-immune pathways that remain to be explored might be involved in females.

Combined effects of social isolation and loneliness on patient-reported outcomes in older adults with HIV

Social isolation exists when one has limited contact with others and is distinct from loneliness, an affective state on the perception of isolation. Less is known about the combined effects of social isolation and loneliness (SI/L) in older persons with HIV (OPWH). Using cross-sectional data on OPWH (age ≥50; N = 146), we assessed the overlap between SI/L and the separate and combined effects of SI/L on patient-reported outcomes (quality-of-life [QoL], HIV-related stigma, and depressive symptoms). Social isolation and loneliness were assessed using Social Network Index and the PROMIS-Social Isolation Scale, respectively, and based on each score, participants were grouped into four categories: "lonely only", "isolated only", "lonely+isolated", or "neither". Among participants (mean age = 56.53), 26.7% were considered "lonely only", 12.3% were "isolated only", 15.1% were "lonely+isolated", and 45.9% were "neither". Adjusted regression models showed that lonely+isolated group had more depressive symptoms and lower QoL than those considered "neither" or "isolated only" (p < .001) and that. The adjusted proportional odds model showed that the odds of stigma were 1.22 and 6.06 higher than those considered "neither" (p < .001) or "lonely only" (p = .016). Results demonstrate the combined effects of SI/L on patient-reported outcomes among OPWH. Findings highlight the need for approaches targeting OPWH who are lonely and isolated.

Broadening the Scope of Resilience in Chronic Pain: Methods, Social Context, and Development

PURPOSE OF REVIEW

A wellspring of new research has offered varying models of resilience in chronic pain populations; however, resilience is a multifaceted and occasionally nebulous construct. The current review explores definitional and methodological issues in existing observational and clinical studies and offers new directions for future studies of pain resilience.

RECENT FINDINGS

Definitions of pain resilience have historically relied heavily upon self-report and from relatively narrow scientific domains (e.g., positive psychology) and in narrow demographic groups (i.e., Caucasian, affluent, or highly educated adults). Meta-analytic and systematic reviews have noted moderate overall quality of resilience-focused assessment and treatment in chronic pain, which may be attributable to these narrow definitions. Integration of research from affiliated fields (developmental models, neuroimaging, research on historically underrepresented groups, trauma psychology) has the potential to enrich current models of pain resilience and ultimately improve the empirical and clinical utility of resilience models in chronic pain.

Development and Validation of an Instrument for Assessing Nurses' Control Sources of Resilience in the COVID-19 Pandemic

Background

Nurses' resilience in the care of patients with Coronavirus Disease 2019 (COVID-19) is essential. This study aimed to develop and validate an instrument for assessing nurses' resilience control resources in the COVID-19 pandemic.

Methods

In this qualitative study, with a conventional content analysis based on a literature review and semi-structured interviews conducted with 20 nurses, the initial draft of the instrument was prepared in different aspects based on a 5-point scale. The instrument's face validity and content validity were examined in 15 nurses and 15 experts, and construct validity was obtained in 482 nurses using the available sampling method. Data were analyzed in SPSS software Version 24 using indexes and analytic tests.

Results

Out of 54 items, 18 items were confirmed by the expert panel and the items had content validity ratio and content validity index scores higher than 0.79. According to the results of an exploratory factor analysis, this tool has 4 dimensions: God, chance, internal locus of control, and powerful others. They accounted for 48.06% of the total variance. CFA showed the indices confirmed the model fit (χ2/df = 1.846, comparative fit index = 0.921, incremental fit index = 0.923, root mean square approximation error = 059, goodness of fit index = 0.905). The reliability of the instrument was acceptable (Ω > 0.70, α > 0.7, CR >0.60, and intra-class correlation coefficients > 0.70).

Conclusion

The developed tool is used to measure the control resources of nurses' resilience in caring for COVID-19 patients. It can help recognize the focus areas for developing appropriate interventions.

Social network size and its relationship to domains of quality-of-life among older persons living with HIV

Gerontological research suggests that social network characteristics are key elements of successful aging as they are related to a positive quality-of-life (QoL). Less is known about the social networks of persons aging with HIV. To describe social network characteristics and assess the effect of social network size on QoL, a sample of 146 OPWH (age ≥50) was recruited from an outpatient HIV clinic in Atlanta, GA. Social network size was assessed using Cohen's social network index (SNI). Domains of QoL (physical, emotional, and social) were assessed using the RAND-36. Descriptive analyses were used to determine the frequency of contact within social networks and multivariable regression models were used to assess the relationship between SNI and three domains of QoL controlling for potential covariates. Participants were predominantly male (60%), heterosexual (63%), and African American (86%). Regular contact occurred most frequently with friends (82%) and relatives (77%). Multivariable modeling revealed that SNI explained 58% of the variance in emotional QoL (R2 = 0.58, F(8, 137) =  25.48, p < .001). Findings provide basis for potential interventions focused on the specific social network to improve emotional QoL of this vulnerable population.

The association of resilience, social connections, and internal locus of control with pain outcomes among older adults

Our objective was to investigate the hypothesis that psychological resources, including resilience, social connections, and internal locus of control, separately and in additive combinations, would be associated with selected pain outcomes: 1) days of opioid use and 2) medical/drug expenditures over 2 years. A mailed survey was sent to a stratified sample of older adults age≥65 with diagnosed back pain, osteoarthritis, and/or rheumatoid arthritis. Each of the resources was dichotomized as high/low and/or counted with equal weighting. Among respondents (N=3,131), the prevalence of mild/no and moderate/severe pain severity was 59% and 41%, respectively. As hypothesized, each resource was associated with lower levels of pain; additively, reported pain severity decreased as the number of resources increased. For moderate/severe pain, there was reduced opioid use among those with more resources; and, for mild/no pain, decreased medical/drug expenditures among those with ≥2 resources. Interventions that integrate psychological resources may enhance their effectiveness.

Resilience as a protective factor in face of pain symptomatology, disability and psychological outcomes in adult chronic pain populations: a scoping review

OBJECTIVES

Patients suffering from chronic pain experience significant disability and disease burden. Resilience has been understood to be a protective factor in face of adversity, eventually contributing to positive outcomes. As such, the current review sought to summarize the existing literature focusing on the roles of resilience in relation to pain phenomenology, pain outcomes (including function and mental health), amongst relevant clinical correlates in a bid to promote holistic management of debilitating chronic pain conditions from a resilience-oriented psychotherapeutic approach as an adjunct to pharmacological treatment.

METHODS

A scoping review was conducted on empirical studies surrounding the theme of resilience in adult chronic pain populations published before 9th May 2021. The following main inclusion criteria was applied; (a) adults diagnosed with chronic pain disorders, (b) use of quantifiable pain measures, (c) use of quantifiable resilience measures. A total of 32 studies were then selected for the review.

RESULTS

First, higher levels of resilience were associated with a reduced likelihood of experiencing any chronic pain, fewer pain sites, better psychological response towards nociception and reduced need for analgesia. Second, higher levels of resilience correlated with better daily and physical function, quality of life, psychosocial functioning and lower likelihood of co-morbid mental health disorders. Third, resilience was an intermediary variable in the pathways from pain phenomenology leading to pain interference, depression and post-traumatic growth.

CONCLUSIONS

The findings were contextualized using pain-disability and resilience frameworks (The Pain and Disability Drivers Model, O'Leary's Resilience models) with suggestions to enhance resilience and contextual factors in the holistic management of adult chronic pain conditions. Future research should examine the differences in resilience between pain types as well as evaluate the efficacy of streamlined resilience-oriented interventions.

Cumulative effect of loneliness and social isolation on health outcomes among older adults

OBJECTIVES

Loneliness and social isolation are described similarly yet are distinct constructs. Numerous studies have examined each construct separately; however, less effort has been dedicated to exploring the impacts in combination. This study sought to describe the cumulative effects on late-life health outcomes.

METHOD

Survey data collected in 2018-2019 of a randomly sampled population of US older adults, age 65+, were utilized (N = 6,994). Survey measures included loneliness and social isolation using the UCLA-3 Loneliness Scale and Social Network Index. Participants were grouped into four categories based on overlap. Groups were lonely only, socially isolated only, both lonely and socially isolated, or neither. Bivariate and adjusted associations were examined.

RESULTS

Among participants (mean age = 76.5 years), 9.8% (n = 684) were considered lonely only, 20.6% (n = 1,439) socially isolated only, 9.1% (n = 639) both lonely and socially isolated, and 60.5% (n = 4,232) neither. Those considered both lonely and socially isolated were more likely to be older, female, less healthy, depressed, with lower quality of life and greater medical costs in bivariate analyses. In adjusted results, participants who were both lonely and socially isolated had significantly higher rates of ER visits and marginally higher medical costs.

CONCLUSION

Results demonstrate cumulative effects of these constructs among older adults. Findings not only fill a gap in research exploring the impacts of loneliness and social isolation later in life, but also confirm the need for approaches targeting older adults who are both lonely and socially isolated. As the COVID-19 pandemic continues, this priority will continue to be urgent for older adults.

Mental Health and Social Support Are Key Predictors of Resilience in German Women with Endometriosis during the COVID-19 Pandemic

Background: Endometriosis is a multifaceted chronic pain disorder that can have an impact on both physical and mental health. Women suffering from chronic pain may be more susceptible to various health disorders, especially during adversity, such as the COVID-19 pandemic. Previous research has identified resilience as a mediator between internal or external stressors and well-being. Methods: An online survey was conducted during the first wave of the COVID-19 pandemic in Germany through patient support groups of women with endometriosis. The Brief Resilience Score (BRS) was employed to evaluate resilience, while the PHQ-4 questionnaire was used to assess self-reported mental health. Univariate and multivariate logistic regression analyses were applied to determine resilience’s independent risk and protective parameters. Results: High educational level was found to be an independent supportive moderator of high resilience in women with a resilience score greater than the study population’s median (BRS > 2.66; OR 2.715; 95% CI 1.472−5.007; p = 0.001) but not in women in the highest resilience score quartile (BRS > 3.33). A decrease in perceived social support was detected to be the most powerful independent risk factor for low resilience: OR 0.541, 95% CI 0.307−0.952, p = 0.033 for predicting BRS > 2.66, and OR 0.397, 95% CI 0.189−0.832, p = 0.014 for predicting scores > 3.33 on the BRS scale. A high burden of mental health symptoms, as measured by the PHQ-4 scale, was negatively associated with resilience. Conclusions: Satisfying social support and good mental health were shown to be key resources for resilience. The results of this study may assist in the identification of women at risk for low resilience and the development of resilience-building strategies in patients with endometriosis.

Predictors of Psychological Distress in Women with Endometriosis during the COVID-19 Pandemic

Background: Endometriosis is a multifaceted chronic pain condition that can have a negative impact on mental health. Patients suffering from chronic pain may face an additional psychological burden during adversity, such as the COVID-19 pandemic. The main aim of this research was to evaluate the prevalence of self-reported depression and anxiety, the influence of demographic, endometriosis-specific, pandemic-specific factors, and resilience on mental health outcomes of patients with endometriosis. Methods: An online survey was conducted through patient support groups of women suffering from endometriosis during the first wave of the COVID-19 pandemic. The PHQ-4 questionnaire, which combines two items of the Patient Health Questionnaire for Depression (PHQ-2) and two items from the Generalized Anxiety Disorder Scale (GAD-2) was used to assess self-reported mental health. The Brief Resilience Score (BRS) was employed to evaluate resilience. Independent risk and protective factors for mental health were investigated by multivariate logistic regression analyses. Results: The PHQ-4 questionnaire was completed by 274 respondents. More than 40% reached depression (PHQ-2) and anxiety (GAD-2) scores of ≥3, and more than 20% achieved PHQ-2 and GAD-2 scores of ≥5. High resilience was found to be a reliable and strong independent protector for the probability of developing adverse psychological outcomes: OR 0.295, p < 0.001 for developing generalized anxiety disorder (GAD-2 ≥ 3), and OR 0.467, p < 0.001 for having major depression (PHQ-2 ≥ 3). Conclusions: Pain-induced disability is an independent risk factor for developing major depression and anxiety, while resilience was identified as a potential protective parameter in terms of positive psychological outcomes in women with endometriosis. The results of this study may help to identify women at risk for adverse mental health outcomes and should encourage healthcare practitioners to establish strategies for the reduction of negative psychological and psychiatric impacts on patients with endometriosis.

The moderating effects of social support and depressive symptoms on pain among elderly multimorbid patients-data from the multicentre, prospective, observational cohort study MultiCare

OBJECTIVES

Depressive symptoms and chronic pain are common among patients with multimorbidity creating a complex medical condition for both the patient and the general practitioner. Perceived social support may function as a protective measure.

To examine the impact of perceived social support as a potential moderator between depressive symptoms and pain intensity and pain disability in daily activities in multimorbid patients aged 75+.

METHOD

Data from 3,189 patients of the German longitudinal cohort study MultiCare were obtained at baseline and follow-ups during 5 years. Multilevel linear mixed-effects analyses were conducted for pain intensity (model 1) and pain disability in daily activities (model 2). The interaction term social support by depression score was included to test for moderation.

RESULTS

The interaction between social support and depressive symptoms was significantly associated with the pain intensity score 0.41 (SE=.17; 95-CI[.08;.74]) but not with the pain disability score 0.35 (SE=.19; 95-CI[-.01;.72]). Additionally, men and individuals with medium or higher educational level showed reduced pain intensity and disability scores. Pain disability scores increased with age and depressive symptoms. Increased pain scores were also found for body mass index and burden of multimorbidity.

CONCLUSION

Perceived social support amplified the association of depressive symptoms on pain intensity and did not show a protective function. The high scores of perceived social support among the participants may point to the practice of secondary gain due to the patients immense health burden.

Loneliness, Social Isolation, and All-Cause Mortality in a Large Sample of Older Adults

Objectives

Using data from a large random sample of U.S. older adults (N = 7982), the effect of loneliness and social isolation on all-cause mortality was examined considering their separate and combined effects.

Methods

The UCLA-3 Loneliness Scale and the Social Network Index (SNI) were used to define loneliness and social isolation. Cox proportional hazards regression models were performed.

Results

Among study participants, there were 548 deaths. In separate, adjusted models, loneliness (severe and moderate) and social isolation (limited and moderate social network) were both associated with all-cause mortality. When modeled together, social isolation (limited and moderate social network) along with severe loneliness remained significantly associated with mortality.

Discussion

Results demonstrate that both loneliness and social isolation contribute to greater risk of mortality within our population of older adults. As the COVID-19 pandemic continues, loneliness and social isolation should be targeted safely in efforts to reduce mortality risk among older adults.

Aging-related Resiliency Theory Development

As a dynamic developmental process, the older population further displays the capacity to resist change over time, improve resilience, and keep a basis for the continuity working and progress over positive management of detrimental consequences of life risks and difficulties. This study aims at developing a theory that endeavors to explore the process of developing aging-related resiliency in people's later in life that can lead to a successful aging experience. In the development of a theory, this study utilized a deductive reasoning approach specifically, using the axiomatic approach. Aging-related Resiliency Theory was efficaciously developed by three propositions generated from four axioms that were derived after reviewing several sets of literature and studies. This developed theory implies that various deleterious events in life activate older persons to respond, adapt, and recover effectively. Acceptance emerges as they acknowledge the natural effects of aging while taking adaptive strategies and supportive resources to be resilient to one's environment. In this sense, it impacts their optimistic outlook towards successful aging. Based on the extraction of axioms, such propositions denoted those older adults call to respond with their total capacity to accept, adapt, recover, and continuously resist deleterious life experiences while using enriched coping strategies and resources towards an optimistic outlook in achieving successful aging. Therefore, emphasizing to improve their capacity to respond to natural decline to essential processes could benefit them at promoting a healthier life span.

Resiliência para uma Velhice Bem-Sucedida: Mecanismos Sociais e Recursos Pessoais de Proteção

Resumo O contexto de modificações e de adversidades decorrentes do envelhecimento exige flexibilidade na adaptação e no ajustamento às situações, a fim de proporcionar um desenvolvimento equilibrado e saudável na velhice. Objetivou-se analisar a compreensão de idosos acerca dos fatores de proteção que promovem resiliência, em resposta aos desafios advindos do processo de envelhecimento e da velhice. Participaram de grupos focais 15 idosos (com idades de 63 a 81 anos), que resultaram em três categorias de análise qualitativa: a) Mecanismos sociais de proteção; b) Recursos pessoais; e c) Processos adaptativos para uma velhice bem-sucedida. O apoio social, dado, principalmente, por grupos de convivência, e a percepção de interações positivas entre familiares, permeadas por afeto e reciprocidade, foram essenciais para manter o bem-estar dos idosos. Os recursos pessoais que exprimem estados e processos emocionais, cognitivos e comportamentais positivos permearam os discursos sobre o bem-envelhecer. Ademais, a adaptação às mudanças ocorridas com o avançar do envelhecimento, o amadurecimento, a aceitação e a construção de uma identidade positiva sobre a velhice denotaram processos de resiliência, pautados no equilíbrio entre as perdas e os ganhos ao longo do desenvolvimento. Conclui-se que o enfrentamento das adversidades do envelhecimento atrelado à valorização e à intensificação de qualidades humanas propicia modos de envelhecer com resiliência.

Does Resiliency Mediate the Association of Psychological Adaptability with Limitations and Pain Intensity after Upper Extremity Trauma?

BACKGROUND

Given the influence of psychosocial factors on musculoskeletal symptoms and limitations, this study assessed if the ability of resilience (an individual's ability to adapt under stress) mediates the association of psychological adaptability with magnitude of physical limitations and pain intensity during recovery from an upper extremity injury.

METHODS

A total of 107 patients were enrolled in this prospective, longitudinal, observational cohort study. Patients completed the Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS PF), an 11-point ordinal measure of pain intensity, the Brief Resilience Scale (BRS), and the Psychological Adaptation Scale (PAS). We used structural equation modeling to assess the mediation effect by resiliency and psychological adaptability on patient-reported disability and pain at initial assessment and after three months.

RESULTS

PAS and BRS were not independently associated with PROMIS PF or pain intensity at enrollment or after three months, so it was not possible to assess if resiliency mediated the association of psychological adaptability with physical function or pain. There were no factors independently associated with resilience.

CONCLUSION

General measures of psychological adaptability and resiliency do not correlate with symptoms and limitations as well as specific measures of adaptiveness in response to nociception.

Resilience in women with primary Sjögren's syndrome

To assess the relationship between resilience and several diseases and individual features in primary Sjӧgren's Syndrome (SS) patients. Resilience was assessed using the Resilience Scale (RS-14). Disease activity, damage, and reported symptoms were assessed by means of ESSDAI (EULAR Sjögren's syndrome disease activity index), SSDDI (Sjӧgren's Syndrome Disease Damage Index) and ESSPRI (EULAR Sjӧgren's Syndrome Patient Reported Index). EuroQol, HADS (Hospital Anxiety and Depression Scale), SF-12 (Short-form 12 health survey), FAS (Fatigue Assessment Scale), FACIT-F (Functional Assessment of Chronic Illness Therapy - Fatigue), and IPAQ (International Physical Activity Questionnaire) questionnaires were submitted to evaluate physical and mental well-being of the recruited patients. Data about the autoimmune profile, systemic manifestations, and current therapy were collected. Educational qualifications and work activities were also considered. Descriptive, correlational, and linear regression analysis were performed. 74 consecutive women with primary SS and 74 sex and age-matched healthy subjects as a control group were recruited. SS patients displayed a moderate value of resilience (median 78.5) with no significant difference compared to controls (p = 0.38). An inverse relationship was found between resilience and mood disorders such as anxiety (p = 0.038) and depression (p < 0.001). Greater resilience was associated with a better perception of the quality of life (p = 0.02) and general health (p < 0.001), as well as with less fatigue (p = 0.008) and a more physically active lifestyle (p = 0.001). No significant relationship was found neither between resilience and age, socio-demographic and disease characteristics, nor with ESSDAI (p = 0.26), ESSPRI (p = 0.83) and SSDDI (p = 0.67). This is the first study assessing resilience in a large group of unselected primary SS patients. Most resilient primary SS patients are less depressed and show a better perception of their health. Greater resilience tends to correlate with less anxiety, physical and mental fatigue, and a more active lifestyle, while no association with disease activity and duration, damage, and socio-demographic features was detected. Considering the well-known role of resilience in helping to better cope with chronic illnesses, its assessment in SS patients should not be overlooked and the possible strategies for its improvement should be better explored and further implemented.

Psychosocial Factors Associated with Sleep Quality and Duration Among Older Adults with Chronic Pain

Sleep complaints are common among older adults with chronic pain. Because of the risk of significant side effects, sleep medications are not recommended as first-line treatments. Little is known about the association between positive psychosocial factors and sleep, but further awareness could support non-drug strategies to minimize poor sleep. The purpose of this study was to (1) determine the prevalence of self-reported poor sleep quality and short/long sleep duration in a population of older adults with chronic pain, and (2) examine the associations of negative risk factors, sleep-inducing medications, and positive psychosocial characteristics on sleep outcomes in this population. This study analyzed survey responses from 4201 adults ages ≥65 years with diagnosed back pain, osteoarthritis, and/or rheumatoid arthritis, and at least 1 year of continuous medical and drug plan enrollment. The most commonly reported sleep outcome was short sleep duration (39%), followed by poor sleep quality (22%), and long sleep duration (9%). Based on pharmaceutical claims, prescriptions for opioids (59%) or benzodiazepines (22%) were common. Perceived stress, depression, and pain or sleep prescription medications were independently associated with poor sleep quality and short or long sleep durations. The positive psychosocial factors of higher resilience and more diverse social networks were independently associated with good sleep quality and optimal sleep duration. These results underscore the importance of social and coping factors to sleep, which may provide new opportunities to improve sleep and well-being in older adults with chronic pain.

Developing the Resilience Framework for Nursing and Healthcare

Despite four decades of resilience research, resilience remains a poor fit for practice as a scientific construct. Using the literature, we explored the concepts attributed to the development of resilience, identifying those that mitigate symptoms of distress caused by adversity and facilitate coping in seven classes of illness: transplants, cancer, mental illness, episodic illness, chronic and painful illness, unexpected events, and illness within a dyadic relationship. We identified protective, compensatory, and challenge-related coping-concept strategies that healthcare workers and patients use during the adversity experience. Healthcare-worker assessment and selection of appropriate coping concepts enable the individual to control their distress, resulting in attainment of equanimity and the state of resilience, permitting the resilient individual to work toward recovery, recalibration, and readjustment. We inductively developed and linked these conceptual components into a dynamic framework, The Resilience Framework for Nursing and Healthcare, making it widely applicable for healthcare across a variety of patients.

Relationships Between Pain, Life Stress, Sociodemographics, and Cortisol: Contributions of Pain Intensity and Financial Satisfaction

Objective

The relationship between psychosocial stress and chronic pain is bidirectional. An improved understanding regarding the relationships among chronic pain, life stress, and ethnicity/race will inform identification of factors contributing to health disparities in chronic pain and improve health outcomes. This study aims to assess relationships between measures of clinical pain, life stress, sociodemographics, and salivary cortisol levels.

Methods

A cross-sectional analysis involving data from 105 non-Hispanic White (NHW) and non-Hispanic Black (NHB) participants aged 45–85 years old with or at risk for knee osteoarthritis. Data included sociodemographics, clinical pain, psychosocial stress, and salivary cortisol across five time points over an approximate 12-hour period. Non-parametric correlation analysis, sociodemographic group comparisons, and regression analyses were performed.

Results

Clinical pain and psychosocial stress were associated with salivary cortisol levels, particularly morning waking and the evening to morning awakening slope. With the inclusion of recognized explanatory variables, the Graded Chronic Pain Scale characteristic pain intensity and financial satisfaction were identified as the primary pain and psychosocial measures associated with cortisol levels. Sociodemographic group differences were indicated such that NHB participants reported higher pain-related disability, higher levels of discrimination, lower financial and material satisfaction, and showed higher evening salivary cortisol levels compared to NHW participants. In combined pain and psychosocial stress analyses, greater financial satisfaction, lower pain intensity, and lower depression were associated with higher morning waking saliva cortisol levels while greater financial satisfaction was the only variable associated with greater evening to morning awakening slope.

Conclusion

Our findings show relationships among clinical pain, psychosocial stress, sociodemographic factors, and salivary cortisol levels. Importantly, with inclusion of recognized explanatory variables, financial satisfaction remained the primary factor accounting for differences in morning waking cortisol and evening to morning awakening cortisol slope in an ethnic/racially diverse group of middle aged and older adults with or at risk for knee osteoarthritis.

The impact of internal locus of control on healthcare utilization, expenditures, and health status across older adult income levels

Our objectives were to 1) determine the prevalence of locus of control (LOC) dimensions stratified by older adult income levels; 2) characterize internal LOC attributes within income subgroups; and 3) investigate LOC associations with healthcare utilization and expenditures; self-rated health and functionality. The survey sample was identified from adults age ≥65 years with diagnosed pain conditions. Internal LOC characteristics were determined from logistic regressions; outcomes regression-adjusted. Among respondents, internal prevalence for low (N = 554), medium (N = 1,394) and high income (N = 2040) was 27%, 30% and 30%, respectively. Internal was associated with high resilience, less stress, exercise and less opioid use across income levels. Lower-income internal was additionally associated with diverse social networks, physical therapy and less drug use. Those with high internal generally had lower healthcare utilization and expenditures; better self-rated health and functionality. Internal LOC is a powerful positive resource associated with better health outcomes, especially influential for lower income.
