Testing a Positive Psychological Intervention for Osteoarthritis

Mapping review of pain management programmes and psychological therapies for community-dwelling older people living with pain

PURPOSE

Persistent pain is common in older people and people living with frailty. Pain or the impact of pain on everyday life is potentially modifiable. We sought to map research evidence and information from randomised controlled trials (RCTs) of pain management programmes and psychological therapies targeting community-dwelling older people, and explore appropriate strategies and interventions for managing or reducing the negative impact of pain for older people, particularly those with frailty.

METHOD

A mapping review of pain management programmes and psychological therapies for community-dwelling older people living with chronic pain. We searched for systematic reviews of randomised controlled trials and for individual randomised controlled trials and extracted data from eligible studies.

RESULTS

Searches resulted in 3419 systematic review records and 746 RCT records from which there were 33 eligible interventions identified in 31 eligible RCTs (48 reports). Broad aims of the interventions were to: improve physical, psychological, or social functioning; adjust the effects or sensation of pain psychologically; enhance self-care with self-management skills or knowledge. Common mechanisms of change proposed were self-efficacy enhanced by self-management tasks and skills, using positive psychological skills or refocusing attention to improve responses to pain, and practising physical exercises to improve physiological well-being and reduce restrictions from pain. Content of interventions included: skills training and activity management, education, and physical exercise. Interventions were delivered in person or remotely to individuals or in groups, typically in 1-2 sessions weekly over 5-12 weeks.

CONCLUSION

All the evaluated interventions appeared to show potential to provide some benefits to older people. None of the included studies assessed frailty. However, some of the included interventions appear appropriate for community-dwelling older people living with both frailty and pain.

Clinical value of ankle flexion and extension exercises combined with a psychological intervention in knee osteoarthritis

BACKGROUND

Considering the limited effectiveness of clinical interventions for knee osteoarthritis (KOA), it is necessary to continue to explore appropriate and effective treatment strategies to improve the condition of KOA patients.

AIM

To clarify the influence of ankle flexion and extension exercises combined with a psychological intervention on the psychological status and activities of daily living (ADLs) of patients with KOA.

METHODS

The research participants were 116 KOA patients admitted to The First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine between May 2019 and May 2022, including 54 patients receiving routine treatment, care and psychological intervention (control group) and 62 patients additionally treated with ankle flexion and extension exercises (research group). The two groups were comparatively analyzed in terms of psychological status (Self-rating Anxiety/Depression Scale, SDS/SAS), ADLs, knee joint function (Lysholm Knee Scoring Scale), pain (Visual Analog Scale, VAS), fatigue (Multidimensional Fatigue Inventory, MFI), and quality of life (QoL; Short-Form 36 Item Health Survey, SF-36).

RESULTS

After evaluation, it was found that the postinterventional SDS, SAS, VAS, and MFI scores in the research group were significantly reduced compared with the baseline (before the intervention) values and those of the control group, while the postinterventional Lysholm, ADL and SF-36 scores were markedly elevated.

CONCLUSION

Therefore, ankle flexion and extension exercises are highly effective in easing negative psychological status, enhancing ADLs, daily living ability, knee joint function and QoL, and relieving pain and fatigue in KOA patients, thus warranting clinical promotion.

Nonpharmacological approaches for pain and symptoms of depression in people with osteoarthritis: systematic review and meta-analyses

People with osteoarthritis often experience pain and depression. These meta-analyses examined and compared nonpharmacological randomized controlled trials (RCTs) for pain and symptoms of depression in people living with osteoarthritis. RCTs published up until April 2022 were sourced by searching electronic databases EMBASE, PUBMED & MEDLINE, Web of Science, CINAHL and PEDro. Random-effects meta-analyses were performed to calculate pooled effect sizes (ES) and 95% confidence intervals (CI) for pain and depression. Subgroup analyses examined intervention subtypes. For pain, 29 interventions (n = 4382; 65 ± 6.9 years; 70% female), revealed a significant effect on reducing pain (ES = 0.43, 95% CI [0.25, 0.61], p < 0.001). Effect sizes were significant (p < 0.001) for movement meditation (ES = 0.52; 95% CI [0.35, 0.69]), multimodal approaches (ES = 0.37; 95% CI [0.22, 0.51]), and psychological therapy (ES = 0.21; 95% CI [0.11, 0.31]), and significant (p = 0.046) for resistance exercise (ES = 0.43, 95% CI [- 0.07, 0.94]. Aerobic exercise alone did not improve pain. For depression, 28 interventions (n = 3377; 63 ± 7.0 years; 69% female), revealed a significant effect on reducing depressive symptoms (ES = 0.29, 95% CI [0.08, 0.49], p < 0.001). Effect sizes were significant for movement meditation (ES = 0.30; 95% CI [0.06, 0.55], p = 0.008) and multimodal interventions (ES = 0.12; 95% CI [0.07, 0.18], p < 0.001). Resistance/aerobic exercise or therapy alone did not improve depressive symptoms. Mind-body approaches were more effective than aerobic/resistance exercise or therapy alone for reducing pain and depression in people with osteoarthritis.Systematic review registration: PROSPERO CRD42022338051.

Positive psychology interventions can improve mental health for chronic pain patients: a systematic review and meta-analysis

OBJECTIVE

This study examines the efficacy of positive psychology interventions (PPIs) for patients with chronic pain through a systematic review and meta-analysis. PPIs are defined as strategies that involve focusing on positive emotions, thoughts, and behaviors that improve mental health by increasing mental well-being and reducing psychological distress.

DESIGN

The search was conducted using the PubMed, Scopus, PsycINFO, and Cochrane Library databases.

MAIN OUTCOME MEASURES

Subjective, psychological, and social well-being were used as indicators of mental well-being, and depression, anxiety, and stress symptoms were used as indicators of psychological distress. Results: Nine studies were included. Eight studies evaluated subjective well-being, seven evaluated depression, and three evaluated anxiety symptoms. No studies examined psychological well-being, social well-being, or stress. PPIs were found to be effective in promoting subjective well-being post-treatment (Hedges' g = 0.40; 95% CI [0.06, 0.73]) and reducing anxiety (Hedges' g = -0.32, 95% CI [-0.59, -0.06]), but no significant results were found for depression (Hedges' g = -0.23, 95% CI [-0.50, 0.04]).

CONCLUSION

The included investigations, while limited, suggest the utility of PPIs in mitigating the psychological consequences of chronic pain. Researchers and practitioners are encouraged to implement PPI practices.

Examining Physical and Cognitive Function in Chronic Low Back Pain Through the Use of a Multisystem Resilience Framework

OBJECTIVES

Chronic pain results in significant impairment in older adults, yet some individuals maintain adaptive functioning. Limited research has considered the role of positive resources in promoting resilience among older adults. Likewise, these factors have largely been examined independently. We aimed to identify resilience domains based on biopsychosocial factors and explore whether resilience phenotypes vary across sleep disturbance, fatigue, and cognitive function.

METHODS

Sixty adults (ages ≥60 years) with chronic low back pain completed measures of psychological, health, and social functioning. On the basis of previously published analyses, principal-components analysis was conducted to create composite domains for these measures, followed by cluster analysis to identify phenotypes.

RESULTS

Four profiles emerged: Cluster 1, with high levels of psychosocial and health-related functioning; Cluster 2, with high health-related functioning and low psychosocial functioning; Cluster 3, with high psychosocial functioning and poorer health; and Cluster 4, with low levels of functioning across all domains. Significant differences across cluster membership emerged for sleep disturbance (ηp2 = 0.29), fatigue (ηp2 = 0.29), and cognitive abilities (ηp2 = 0.47). Individuals with the highest levels of resilience demonstrated more optimal outcomes in sleep and fatigue (P values ≤0.001) than did individuals with a less resilient phenotype. Furthermore, the High-Resilience group (Cluster 1) and the High Psychosocial / Low Health group (Cluster 3) had lower cognitive impairment than did the High Health / Low Psychosocial group (Cluster 2) and the Low-Resilience group (Cluster 4) (P values ≤0.009).

CONCLUSIONS

A higher array of protective resources could buffer against the negative sequelae associated with chronic low back pain. These exploratory findings support the multidimensional nature of resilience and suggest that targeting resilience from a multisystem perspective might help to optimize interventions for older adults with chronic pain.

Surgeons Attitude toward Psychosocial Aspects of Trapeziometacarpal Osteoarthritis

Background  There is notable evidence that unhelpful thoughts (symptoms of anxiety and depression) increase symptom intensity among patients with trapeziometacarpal osteoarthritis (TMC OA). Surgeons may or may not be mindful of this line of evidence when interacting with patients. In a survey-based experiment, we randomized surgeons to be prompted about the psychosocial aspects of TMC OA. We aimed to measure the influence of mindfulness of mental health on treatment recommendations and willingness to discuss mental health interventions. Methods  We randomized 121 hand surgeons to read one of two paragraphs: (A) about biomedical treatment options for TMC OA, or (B) about the impact of mental and social aspects on TMC OA. Thereafter, surgeons were asked several questions about their opinions and treatment recommendations. Results  We found that prompting surgeons with information about the psychosocial aspects of TMC OA did not influence their attitudes or treatment recommendations. Most surgeons were willing to offer patients a workbook (92%) or psychologist referral (84%). Among the few surgeons declining to refer, their reasoning was "it would not be of any help" and "stigmatization." Conclusion  The observation that a paragraph to encourage mindfulness about the psychosocial aspects of TMC OA, which had no influence on surgeon opinions, suggests that awareness may not be a major factor accounting the relatively limited implementation of this evidence in practice to date. Surgeons seem aware of the importance of psychological influence and barriers may include availability, stigma, and a sense of futility. This is a diagnostic study that reflects level of evidence III.

Lessons in Affect Regulation to Keep Stress and Pain UndeR control (LARKSPUR): Design of a randomized controlled trial to increase positive affect in middle-aged and older adults with fibromyalgia

BACKGROUND

Fibromyalgia syndrome (FMS) is a leading cause of functional limitations and disability for which there is no cure. Positive psychological interventions for improving health have received increasing attention, but evidence of the feasibility, acceptability, and impact of such interventions in adult populations with FMS is limited.

OBJECTIVES

To describe the rationale and design of a 5-week, online positive affect skills intervention, LARKSPUR: Lessons in Affect Regulation to Keep Stress and Pain UndeR control.

METHODS

FMS participants (N = 90) will be randomized to one of two conditions: (1) LARKSPUR or (2) emotion reporting/attention control. LARKSPUR is an online multicomponent intervention that targets eight skills to help foster positive affect: (1) noticing positive events, (2) savoring positive events, (3) identifying personal strengths, (4) behavioral activation to set and work toward attainable goals, (5) mindfulness, (6) positive reappraisal, (7) gratitude, and (8) acts of kindness. The primary outcomes include feasibility (i.e., recruitment, retention, adherence) and acceptability (i.e., helpfulness, usability, satisfaction). Secondary outcomes include pain intensity and pain interference.

SIGNIFICANCE

If feasibility and acceptability metrics are met and reductions in pain outcomes are achieved, we will undertake future efficacy and effectiveness trials of LARKSPUR among older adults with FMS.

Long noncoding RNA H19 alleviates inflammation in osteoarthritis through interactions between TP53, IL-38, and IL-36 receptor

Aims

Osteoarthritis (OA) is a common degenerative joint disease characterized by chronic inflammatory articular cartilage degradation. Long noncoding RNAs (lncRNAs) have been previously indicated to play an important role in inflammation-related diseases. Herein, the current study set out to explore the involvement of lncRNA H19 in OA.

Methods

Firstly, OA mouse models and interleukin (IL)-1β-induced mouse chondrocytes were established. Expression patterns of IL-38 were determined in the synovial fluid and cartilage tissues from OA patients. Furthermore, the targeting relationship between lncRNA H19, tumour protein p53 (TP53), and IL-38 was determined by means of dual-luciferase reporter gene, chromatin immunoprecipitation, and RNA immunoprecipitation assays. Subsequent to gain- and loss-of-function assays, the levels of cartilage damage and proinflammatory factors were further detected using safranin O-fast green staining and enzyme-linked immunosorbent assay (ELISA) in vivo, respectively, while chondrocyte apoptosis was measured using Terminal deoxynucleotidyl transferase dUTP Nick-End Labeling (TUNEL) in vitro.

Results

IL-38 was highly expressed in lentivirus vector-mediated OA mice. Meanwhile, injection of exogenous IL-38 to OA mice alleviated the cartilage damage, and reduced the levels of proinflammatory factors and chondrocyte apoptosis. TP53 was responsible for lncRNA H19-mediated upregulation of IL-38. Furthermore, it was found that the anti-inflammatory effects of IL-38 were achieved by its binding with the IL-36 receptor (IL-36R). Overexpression of H19 reduced the expression of inflammatory factors and chondrocyte apoptosis, which was abrogated by knockdown of IL-38 or TP53.

Conclusion

Collectively, our findings evidenced that upregulation of lncRNA H19 attenuates inflammation and ameliorates cartilage damage and chondrocyte apoptosis in OA by upregulating TP53, IL-38, and by activating IL-36R.

Demographic and disease characteristics associated with pain intensity, kinesiophobia, balance, and fall self-efficacy among people with osteoarthritis: a cross-sectional study

BACKGROUND

Osteoarthritis (OA) is a common degenerative joint disease leading to significant pain, mobility limitation, economic burden, reduced quality of life, and disability among adults globally. Psychological factors related to pain intensity (PI), kinesiophobia, fall self-efficacy (FSE), and balance may lead to a poor OA prognosis. This study was designed to explore the association between PI, kinesiophobia, FSE, balance, and age, gender, marital status, site of OA, duration, symmetry, comorbidity, and adaptive behaviours among patients with knee or hip OA.

METHODS

This cross-sectional study involved 70 purposively selected participants aged 59.91 ± 11.12 years. Numeric pain rating scale, Tampa scale for kinesiophobia, fall-efficacy scale, and timed up and go test were used to measure PI, kinesiophobia, FSE, and balance, respectively. Statistical analyses were completed with the Pearson correlation test, independent samples t-test, and multiple linear regression.

RESULTS

The participants were mainly women (n = 59, 84.3%). However, there was no gender difference in the reported PI, kinesiophobia, FSE, and balance. There was a significant correlation between FSE and balance (r = 0.422, p<0.001). Kinesiophobia was significantly associated with the presence of comorbidity (β = 0.240, p = 0.001) and knee OA (β = 0.208, p<0.042). There was an association between FSE and the use of a walking aid (β = -0.442, p<0.042), stop-for-rest during walking (β = -0.292, p = 0.002), presence of comorbidity (β = 0.209, p = 0.014), and bilateral lower limb OA (β = 0.167, p = 0.057). Balance was associated with the use of a walking aid (β = -0.421, p<0.001) and stop-for-rest during walking (β = - 0.294, p = 0.006).

CONCLUSION

Osteoarthritis-related psychological distress affects both men and women. This study support integration of psychological outcomes in the assessment, management, and follow-up of people with lower limb osteoarthritis. Moreover, comorbidity worsened psychological distress among people with osteoarthritis. Therefore, the traditional biomedical management of osteoarthritis can be optimised by timely diagnosis and treatment of comorbidities, and the inclusion of psychotherapy.

The Relationship Between Loneliness and Positive Affect in Older Adults

OBJECTIVE

To establish whether positive affect (PA) is uniquely associated with loneliness and other social functioning variables beyond negative affect (NA) among older adults.

METHODS

Four hundred and twenty-eight participants (aged 60+ years old, 82% White, and 48% female) were recruited using random digit-dialing and completed scales for loneliness (UCLA Loneliness Scale), companionship (PROMIS scale), satisfaction with discretionary social activities (PROMIS scale), PA (Center for Epidemiologic Studies [CES] Happiness Scale), and NA (CES-Depression scale and Brief Symptom Inventory-Anxiety Subscale).

RESULTS

Multiple linear regression models found PA to be a significant predictor of lower loneliness where the effect of PA on loneliness is dependent on the level of NA; a large effect size at the mean level of NA, which becomes attenuated when NA increases. Although the direction of effect of PA on loneliness will change for NA > 5.10, which is 5 standard deviations away from 0, based on the model estimates, the percent of subjects with this large NA levels is practically 0. Thus, higher PA is associated with lower loneliness, however this effect is attenuated for larger NA. Similarly, multiple linear regression models found that companionship was associated with PA and NA where the effect of PA is dependent on the level of NA; a medium effect size at the mean level of NA, which becomes attenuated when NA increases. As in the case of loneliness, the direction of effect of PA on companionship will change for NA > 3.52, which is 3.5 standard deviation away from 0, based on the model estimates, but the percent of subjects with this large NA levels is practically 0. Thus, higher PA is associated with increased companionship, aand this effect is attenuated with greater NA. Satisfaction with social activities was associated with PA only (medium effect size).

CONCLUSION

Results suggest PA appears to be uniquely associated with social functioning among older adults. These findings support the potential for treatments that target PA to decrease loneliness among older adults, or vice versa.

OUP accepted manuscript

BACKGROUND AND OBJECTIVES

Experiencing structural racism over the life course contributes to disproportionate pain-related disability among African American older adults. Positive STEPS, delivered by community health workers, is a culturally congruent chronic pain self-management intervention that incorporates positive psychology principles and gives attention to social determinants of pain and pain management.

RESEARCH DESIGN AND METHODS

We conducted a randomized pilot trial among older adults with chronic musculoskeletal pain in an underserved, primarily African American community (Detroit, Michigan). The 7-week intervention included weekly telephone sessions with a community health worker; web-based videos teaching pain self-management skills; positive activities (e.g., Life Review, Gratitude Jar); and use of wearable activity trackers. Outcomes were measured at baseline and 8-week follow-up. We assessed participant retention, engagement, and satisfaction.

RESULTS

Study completers (n = 46; 90% retention) were 93% African American, 89% female, mean 72 years, and completed 5.7 of 7 sessions. Intervention participants versus controls showed greater improvement in PROMIS Pain Interference (4.3-point T-score decrease vs. 0.4-point increase; p = .01) and the Pain Self-Efficacy Questionnaire (p = .007). Furthermore, compared with controls, significantly more intervention participants reported "better" or "much better" global functioning (86% vs. 25%; p = .000) and pain (67% vs. 21%; p = .003) since baseline. Improvements in physical functioning, social participation, and resilience were noted, but differences were not significant. Participant feedback on the intervention was overwhelmingly positive.

DISCUSSION AND IMPLICATIONS

A community health worker-led chronic pain self-management intervention combining positive activities with self-management skills training demonstrated the potential to enhance pain-related functioning among a vulnerable group of older adults.

Six-Week Online Multi-component Positive Psychology Intervention Improves Subjective Wellbeing in Young Adults

Improving mental wellbeing has a range of benefits for society, including increased productivity, longevity, and resiliency. However, interventions designed to improve mental wellbeing are often only compared to waitlist controls, leaving uncertainty regarding the mechanisms of their effectiveness. The current study in 326 participants assessed a six-week positive psychology intervention against an active control (n = 163) in an online randomized control trial. Outcome measures included life satisfaction, wellbeing (subjective and psychological wellbeing), stress, depression and anxiety symptoms, and self-compassion. The potential moderating effect of participating during the ongoing COVID-19 pandemic was also explored. The intervention group showed greater improvements in life satisfaction by week six (β = 0.18, p = .014) and were maintained through to 7 weeks post-baseline (β = 0.23, t = 3.07, p = .002) and remained significant when accounting for COVID-19 restrictions. An improvement in composite wellbeing from baseline to 7 weeks post-baseline was detected when accounting for COVID-19 restrictions. Composite wellbeing and total depression and anxiety symptoms improved significantly more in the intervention group for participants with low baseline resiliency resources. These findings support the efficacy of using online multi-component positive psychology interventions in boosting wellbeing and reducing distress symptoms particularly in individuals with fewer resiliency resources who may need added support.

Virtual Mind-Body Program for Obese Knee Osteoarthritis Patients with Comorbid Depression: Development and Feasibility Pilot (Preprint)

Background

Knee osteoarthritis (KOA) is the most common joint disorder in the United States and a leading cause of disability. Depression and obesity are highly comorbid with KOA and accelerate knee degeneration and disability through biopsychosocial mechanisms. Mind-body physical activity programs can engage biological, mechanical, and psychological mechanisms to improve outcomes in KOA, but such programs are not currently available.

Objective

This mixed methods study aims to adapt a mind-body activity program for the unique needs of patients with KOA, depression, and obesity (GetActive-OA) delivered via live video.

Methods

Participants were adults (aged ≥45 years) from rural Kentucky with obesity (BMI≥30 kg/m²), idiopathic KOA with mild to moderate radiographic changes, and elevated depressive symptoms (9-item Patient Health Questionnaire ≥10) recruited from 2 orthopedic centers. In phase 1, we developed GetActive-OA and the study protocol using qualitative focus group feedback from the study population (N=9; 2 focus groups, 90 minutes) and multidisciplinary expertise from clinical psychologists and orthopedic researchers. In phase 2, we explored the initial feasibility, credibility, and acceptability of GetActive-OA, live video delivery, and study procedures via an open pilot with exit interviews (N=5; 1 group). This research was guided by National Institutes of Health (NIH) model stage IA.

Results

Phase 1 qualitative analyses revealed nuanced information about challenges with coping and increasing activity, high interest in a mind-body activity program, program participation facilitators (flexibility with technology) and barriers (amotivation and forgetfulness), and perceived challenges with data collection procedures (blood and urine samples and homework). Phase 2 quantitative analyses showed that GetActive-OA met most a priori feasibility markers: acceptability (80%), expectancy (100%), credibility (100%), clinician adherence (90%), homework adherence (80%), questionnaire data collection (100%), program satisfaction (100%), and safety (100%). Adherence to ActiGraph wear (80% baseline, 20% posttest) and collection of blood samples (60%) were low. Participation in GetActive-OA was associated with signals of improvements in general coping (Cohen d=2.41), pain catastrophizing (Cohen d=1.24), depression (Cohen d=0.88), anxiety (Cohen d=0.78), self-efficacy (Cohen d=0.73), pain (Cohen d=0.39), and KOA symptoms (Cohen d=0.36). Qualitative exit interviews confirmed quantitative findings and provided valuable information to optimize the program and protocol.

Conclusions

Patients with KOA, depression, and obesity from rural Kentucky were interested in a live video mind-body activity program. GetActive-OA shows promise; however, the program and protocol require further NIH stage I refinement before formal efficacy testing (NIH model stage II).

Adaptability and Resilience in Aging Adults (ARIAA): protocol for a pilot and feasibility study in chronic low back pain

Background

Chronic low back pain (cLBP) is the leading cause of disability among older adults and one of the top reasons for seeking healthcare, resulting in significant decrements in physical functioning. Because older adults are among the fastest growing cohorts in the USA, both the incidence and burden of cLBP are expected to increase considerably, rendering geriatric pain management a top health priority. Resilience is defined as a process allowing individuals to adapt and recover from adverse and stressful conditions, and it has been highlighted as a crucial factor in positive health-related functioning. While a growing body of literature supports the use of resilience-based interventions in chronic pain, research examining their effectiveness in older adults with cLBP remains limited. The primary aims of the study are to assess the feasibility and acceptability of a psychologically oriented resilience intervention among aging adults with cLBP.

Methods

In this article, we describe the rationale and design of the Adaptability and Resilience in Aging Adults (ARIAA) study, a single-arm intervention in which 60 participants (ages ≥ 60 years) with cLBP will be recruited to participate in a 7-week group-based program aimed at enhancing psychological resilience. Intervention sessions will target positive psychology concepts (e.g., positive affect, pain acceptance, hopeful thinking, pain self-efficacy) and cognitive behavioral techniques that have established benefits in pain management. Primary study outcomes include intervention feasibility and acceptability as measured by treatment engagement, intervention credibility and satisfaction, ability to meet recruitment and retention metrics, and the feasibility of questionnaire and home activity completion. Outcomes will be assessed at baseline, immediately at posttreatment, and at the 3-month follow-up period.

Discussion

This study will establish the feasibility and acceptability of a novel intervention aimed at enhancing positive, psychological functioning, and resilience in older adults with cLBP. Achievement of these aims will provide a rich platform for future intervention research targeting improvements in pain and disability among geriatric populations and will serve as a foundation for a fully powered trial to examine treatment efficacy of the proposed intervention.

Feeling Good Despite EDS: The Effects of a 5-Week Online Positive Psychology Programme for Ehlers-Danlos-Syndromes Patients

Ehlers–Danlos-Syndromes (EDS) is a group of hereditary, chronic and potentially disabling conditions. Few studies have tested the effects of psychological interventions to increase well-being in this population. We hypothesized that Positive Psychology Interventions (PPI), first applied to healthy and mentally ill subjects, can also be useful for people with somatic conditions and conducted a study to evaluate the efficacy of a 5-week online PPI designed to improve well-being in EDS patients. A sample of 132 EDS patients were allocated to three groups: assigned PPI, self-selected PPI, and waitlist control-group (WLC). Measures of positive and negative affect, pain disability, fatigue, and life satisfaction were administered before program start, 6 weeks later, and 1 month later. Satisfaction with the program was also evaluated. The results revealed that participants in the self-selected PPI-group, but not in the assigned PPI group, reported significantly lower levels of fatigue and higher levels of positive affect and life satisfaction compared to WLC after 6 weeks. There were no effects on negative affect and pain disability measures. Finally, 77% of the participants were satisfied or very satisfied with the program. These findings confirm and extend previous research by showing the efficacy of PPI for people with chronic illness under the condition that individuals can choose the program content. From a healthcare perspective, online PPIs could complement treatments aimed at symptom reduction and increase well-being in patients with EDS.

Are positive psychology interventions efficacious in chronic pain treatment? A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

Although positive psychology interventions are increasingly popular in chronic pain treatment their efficacy is still unclear. The objective is to summarize evidence on the effect of positive psychology interventions (PPIs) on pain, physical functioning, and emotional functioning in adults with chronic pain.

METHODS

Four electronic databases and additional references were searched for randomized controlled trials published between 1990 and 2020. Findings from included studies were qualitatively and quantitatively synthesized, and study quality was assessed for risk of bias. A random effects meta-analysis model was applied for outcomes with more than four findings.

RESULTS

Of 16 included randomized controlled trials, almost half delivered positive psychology interventions as self-help online interventions, and half conducted guided face-to-face interventions which lasted mostly eight weeks. Results from meta-analysis showed beneficial effects of positive psychology interventions compared to the control group on pain intensity and emotional functioning (i.e., less depressive symptoms, pain catastrophizing, negative affect; more positive affect) post-intervention. At 3-month follow-up, beneficial effects were maintained for depressive symptoms and positive and negative affect, but not for pain catastrophizing. However, the evidence on the long-term efficacy of PPIs and the efficacy of PPIs on physical functioning remains limited.

CONCLUSION

This review supports the notion that positive psychology interventions are beneficial to chronic pain treatment, although further, high quality research is needed to support this conclusion.

Complementary and integrative health approaches to manage chronic pain in U.S. military populations: Results from a systematic review and meta-analysis, 1985-2019

The objective of this study was to examine the efficacy of complementary and integrative health (CIH) approaches for reducing pain intensity (primary outcome) and depressive symptoms (secondary outcome) as well as improving physical functioning (secondary outcome) among U.S. military personnel living with chronic pain. Studies were retrieved from bibliographic databases, databases of funded research, and reference sections of relevant articles. Studies that (a) evaluated a CIH approach to promote chronic pain management among military personnel, (b) used a randomized controlled trial design, and (c) assessed pain intensity were included. Two coders extracted data from each study and calculated effect sizes. Discrepancies between coders were resolved through discussion. Comprehensive searches identified 12 studies (k = 15 interventions) that met inclusion criteria. CIH practices included cognitive-behavioral therapies (k = 5), positive psychology (k = 3), yoga (k = 2), acupuncture (k = 2), mindfulness-based interventions (k = 2), and biofeedback (k = 1). Across these studies, participants who received the intervention reported greater reductions in pain intensity (d+ = 0.44, 95% CI [0.21, 0.67], k = 15) compared to controls. Statistically significant improvements were also observed for physical functioning (d+ = 0.36, 95% CI [0.11, 0.61], k = 11) but not for depressive symptoms (d+ = 0.21, 95% CI [-0.15, 0.57], k = 8). CIH approaches reduced pain intensity and improved physical functioning. These approaches offer a nonpharmacological, nonsurgical intervention for chronic pain management for military personnel. Future studies should optimize interventions to improve depressive symptoms in military populations experiencing chronic pain. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

A systematic review and meta-analysis of psychological interventions to improve mental wellbeing

Our current understanding of the efficacy of psychological interventions in improving mental states of wellbeing is incomplete. This study aimed to overcome limitations of previous reviews by examining the efficacy of distinct types of psychological interventions, irrespective of their theoretical underpinning, and the impact of various moderators, in a unified systematic review and meta-analysis. Four-hundred-and-nineteen randomized controlled trials from clinical and non-clinical populations (n = 53,288) were identified for inclusion. Mindfulness-based and multi-component positive psychological interventions demonstrated the greatest efficacy in both clinical and non-clinical populations. Meta-analyses also found that singular positive psychological interventions, cognitive and behavioural therapy-based, acceptance and commitment therapy-based, and reminiscence interventions were impactful. Effect sizes were moderate at best, but differed according to target population and moderator, most notably intervention intensity. The evidence quality was generally low to moderate. While the evidence requires further advancement, the review provides insight into how psychological interventions can be designed to improve mental wellbeing.

Update on pain in arthritis

PURPOSE OF REVIEW

Osteoarthritis is a degenerative joint disease that features pain as a hallmark symptom. This review summarises progress and obstacles in our understanding of pain mechanisms in arthritis.

RECENT FINDINGS

Pain phenotypes in osteoarthritis are poorly characterized in clinical studies and animal studies are largely carti-centric. Different animal models incur variable disease progression patterns and activation of distinct pain pathways, but studies reporting both structural and pain outcomes permit better translational insights. In patients, classification of osteoarthritis disease severity is only based on structural integrity of the joint, but pain outcomes do not consistently correlate with joint damage. The complexity of this relationship underlines the need for pain detection in criteria for osteoarthritis classification and patient-reported outcome measures.

SUMMARY

Variable inflammatory and neuropathic components and spatiotemporal evolution underlie the heterogeneity of osteoarthritis pain phenotypes, which must be considered to adequately stratify patients. Revised classification of osteoarthritis at different stages encompassing both structural and pain outcomes would significantly improve detection and diagnosis at both early and late stages of disease. These are necessary advancements in the field that would also improve trial design and provide better understanding of basic mechanisms of disease progression and pain in osteoarthritis.

Development of a mind body program for obese knee osteoarthritis patients with comorbid depression

Knee osteoarthritis (OA) is the most common joint disorder in the U.S. and a leading cause of disability. Depression and obesity are highly comorbid among knee OA patients, and the combination of obesity and depression is associated with decreased physical activity, higher pain and disability, and more rapid cartilage degradation. Depression, obesity and OA exacerbate one another and share a common pathophysiology involving systemic inflammation and pro-inflammatory cytokines, reflecting a complex mind-body interaction. Current treatments for knee OA offer little to no benefit over placebo, and do not emphasize mind-body practices or physical activity to target the underlying pathophysiology. Mind-body interventions to lessen depressive symptoms and increase physical activity offer the ability to target biological, mechanical and psychological mechanisms of OA progression. Our long-term goals are to evaluate the mechanisms by which the Relaxation Response Resiliency Program (3RP) delivered via secure telehealth, and adapted for patients with depression, obesity and knee OA (GetActive-OA) promotes increases in physical activity and improved knee health. We hypothesize that the synergistic interaction between mindfulness, adaptive thinking, positive psychology and healthy living skills of the GetActive-OA will slow the progression of symptomatic knee OA by reducing pro-inflammatory cytokine expression and promoting optimal mechanical loading of the cartilage. Here we present the protocol for a mixed methods study that will adapt the 3RP for the needs of knee OA patients with depression and obesity with a focus on increasing physical activity (GetActive-OA), and iteratively maximize the feasibility, credibility and acceptability of the programs and research procedures.

Bouncing back after lumbar spine surgery: early postoperative resilience is associated with 12-month physical function, pain interference, social participation, and disability

BACKGROUND CONTEXT

Positive psychosocial factors early after surgery, such as resilience and self-efficacy, may be important characteristics for informing individualized postoperative care.

PURPOSE

To examine the association of early postoperative resilience and self-efficacy on 12-month physical function, pain interference, social participation, disability, pain intensity, and physical activity after lumbar spine surgery.

STUDY DESIGN/SETTING

Pooled secondary analysis of prospectively collected trial data from two academic medical centers.

PATIENT SAMPLE

Two hundred and forty-eight patients who underwent laminectomy with or without fusion for a degenerative lumbar condition.

OUTCOME MEASURES

Physical function, pain inference, and social participation (ability to participate in social roles and activities) were measured using the Patient Reported Outcomes Measurement Information System. The Oswestry Disability Index, Numeric Rating Scale, and accelerometer activity counts were used to measure disability, pain intensity, and physical activity, respectively.

METHODS

Participants completed validated outcome questionnaires at 6 weeks (baseline) and 12 months after surgery. Baseline positive psychosocial factors included resilience (Brief Resilience Scale) and self-efficacy (Pain Self-Efficacy Questionnaire). Multivariable linear regression analyses were used to assess the associations between early postoperative psychosocial factors and 12-month outcomes adjusting for age, sex, study site, randomized group, fusion status, fear of movement (Tampa Scale for Kinesiophobia), and outcome score at baseline. This study was funded by Patient-Centered Outcomes Research Institute and Foundation for Physical Therapy Research. There are no conflicts of interest.

RESULTS

Resilience at 6 weeks after surgery was associated with 12-month physical function (unstandardized beta=1.85 [95% confidence interval [CI]: 0.29; 3.40]), pain interference (unstandardized beta=-1.80 [95% CI: -3.48; -0.12]), social participation (unstandardized beta=2.69 [95% CI: 0.97; 4.41]), and disability (unstandardized beta=-3.03 [95% CI: -6.04; -0.02]). Self-efficacy was associated with 12-month disability (unstandardized beta=-0.21 [95% CI: -0.37; -0.04].

CONCLUSIONS

Postoperative resilience and pain self-efficacy were associated with improved 12-month patient-reported outcomes after spine surgery. Future work should consider how early postoperative screening for positive psychosocial characteristics can enhance risk stratification and targeted rehabilitation management in patients undergoing spine surgery.

What General and Pain-associated Psychological Distress Phenotypes Exist Among Patients with Hip and Knee Osteoarthritis?

BACKGROUND

Psychological distress can negatively influence disability, quality of life, and treatment outcomes for individuals with hip and knee osteoarthritis (OA). Clinical practice guidelines recommend a comprehensive disease management approach to OA that includes the identification, evaluation, and management of psychological distress. However, uncertainty around the best psychological screening and assessment methods, a poor understanding of the heterogeneity of psychological distress in those with OA, and lack of guidance on how to scale treatment have limited the growth of OA care models that effectively address individual psychological needs.

QUESTIONS/PURPOSES

(1) Across which general and pain-related psychological distress constructs do individuals seeking conservative care for hip or knee OA report higher scores than the general population of individuals seeking conservative care for musculoskeletal pain conditions? (2) What common psychological phenotypes exist among nonsurgical care-seeking individuals with hip or knee OA?

METHODS

The sample included participants from the Duke Joint Health Program (n = 1239), a comprehensive hip and knee OA care program, and the Optimal Screening for Prediction of Referral and Outcome (OSPRO) cohort studies (n = 871) comprising individuals seeking conservative care for knee, shoulder, low back, or neck pain. At the initial evaluation, patients completed the OSPRO Yellow Flag (OSPRO-YF) Assessment Tool, which assesses 11 general and pain-related psychological distress constructs (depression, anxiety, fear of movement, self-efficacy for managing one's own pain). We used OSPRO-YF scores to compare levels of psychological distress between the cohorts. Cohen's d effect sizes were calculated to determine the magnitude of differences between the groups, with d = 0.20, d = 0.50, and d = 0.80 indicating small, medium, and large effect sizes, respectively. We used a latent class analysis to derive psychological distress phenotypes in people with OA based on the 11 OSPRO-YF psychological distress indicators. Psychological distress phenotypes are characterized by specific mood, belief, and behavioral factors that differentiate subgroups within a population. Phenotyping can help providers develop scalable treatment pathways that are better tailored to the common needs of patients.

RESULTS

Patients with OA demonstrated higher levels of general and pain-related psychological distress across all psychological constructs except for trait anxiety (that is, anxiety level as a personal characteristic rather than as a response to a stressful situation, like surgery) with small-to-moderate effect sizes. Characteristics with the largest effect sizes in the OA and overall OSPRO cohort were (Cohen's d) general anxiety (-0.66, lower in the OA cohort), pain catastrophizing (the tendency to ruminate over, maginfiy, or feel helpless about a pain experience, 0.47), kinesiophobia (pain-related fear of movement, 0.46), pain self-efficacy (confidence in one's own ability to manage his or her pain, -0.46, lower in the OA cohort), and self-efficacy for rehabilitation (confidence in one's own ability to perform their rehabilitation treatments, -0.44, lower in the OA cohort). The latent class analysis yielded four phenotypes (% sample): high distress (52%, 647 of 1239), low distress (26%, 322 of 1239), low self-efficacy and acceptance (low confidence in managing and willingness to accept pain) (15%, 186 of 1239), and negative pain coping (exhibiting poor pain coping skills) (7%, 84 of 1239). The classification error rate was near zero (2%), and the median of posterior probabilities used to assign subgroup membership was 0.99 (interquartile range 0.98 to 1.00), both indicating excellent model performance. The high-distress group had the lowest mean age (61 ± 11 years) and highest levels of pain intensity (6 ± 2) and disability (HOOS JR: 50 ± 15; KOOS JR: 47 ± 15), whereas the low-distress group had the highest mean age (63 ± 10 years) and lowest levels of pain (4 ± 2) and disability (HOOS JR: 63 ± 15; KOOS JR: 60 ± 12). However, none of these differences met or exceeded anchor-based minimal clinically important difference thresholds.

CONCLUSIONS

General and pain-related psychological distress are common among individuals seeking comprehensive care for hip or knee OA. Predominant existing OA care models that focus on biomedical interventions, such as corticosteroid injection or joint replacement that are designed to directly address underlying joint pathology and inflammation, may be inadequate to fully meet the care-related needs of many patients with OA due to their underlying psychological distress. We believe this because biomedical interventions do not often address psychological characteristics, which are known to influence OA-related pain and disability independent of joint pathology. Healthcare providers can develop new comprehensive hip and knee OA treatment pathways tailored to these phenotypes where services such as pain coping skills training, relaxation training, and psychological therapies are delivered to patients who exhibit phenotypes characterized by high distress or negative pain coping. Future studies should evaluate whether tailoring treatment to specific psychological phenotypes yields better clinical outcomes than nontailored treatments, or treatments that have a more biomedical focus.

Positive Psychological Factors and Impairment in Rheumatic and Musculoskeletal Disease: Do Psychopathology and Sleep Quality Explain the Linkage?

OBJECTIVE

Little is known about potential mechanisms of action linking protective positive psychological variables and functional disability in patients with rheumatic and musculoskeletal disease. The present study was undertaken to examine symptoms of psychopathology, including stress, depression, anxiety, and sleep quality, as serial mediators of the association between gratitude, self-compassion, self-forgiveness, and functional impairment.

METHODS

We assessed risk and protective factors for functional disability in patients with fibromyalgia (FM), osteoarthritis (OA), rheumatoid arthritis (RA), and ankylosing spondylitis (AS) who were recruited from an Austrian health care facility. Respondents completed online surveys, including the Gratitude Questionnaire 6-item form, the Self-Compassion Scale short form, the Self-Forgiveness and Forgiveness of Others Index, the Perceived Stress Scale 4, the Patient Health Questionnaire 2, the 2-item Generalized Anxiety Disorder Scale, the Sleep Condition Indicator, and the Health Assessment Questionnaire. Bivariate and serial mediation analyses were conducted.

RESULTS

For our sample of 1,218 patients (52% female, n = 632; AS [37%], OA [34%], RA [14%], and FM [24%]), stress, depression, and anxiety, in parallel as first-order mediators, and sleep quality as a second-order mediator, explained the association between positive psychological variables and functional disability.

CONCLUSION

Positive psychological factors exert a beneficial downstream effect on mental well-being, sleep health, and health-related functional impairment. Therapeutic promotion of gratitude, self-compassion, and self-forgiveness may improve mental and physical health in patients with rheumatic and musculoskeletal disease.

Measuring Positive Emotion Outcomes in Positive Psychology Interventions: A Literature Review

Accumulating evidence for the unique social, behavioral, and physical health benefits of positive emotion and related well-being constructs has led to the development and testing of positive psychological interventions (PPIs) to increase emotional well-being and enhance health promotion and disease prevention. PPIs are specifically aimed at improving emotional well-being and consist of practices such as gratitude, savoring, and acts of kindness. The purpose of this narrative review was to examine the literature on PPIs with a particular focus on positive emotion outcomes. We evaluated the evidence on the effects of PPIs on positive emotion specifically, and discussed the range of evidence regarding the relative responsiveness of emotion measures to PPIs in order to gain a better understanding of the specific emotional pathways through which PPIs influence psychological and physical well-being. We conclude with recommendations for best evaluating effects of PPIs on positive emotion outcomes.

Positive affect and chronic pain: a preregistered systematic review and meta-analysis

Chronic noncancer pain (CNCP) is a significant health burden among adults. Standard behavioral therapies typically focus on targeting negative affect (NA) and yield only modest treatment effects. The aims of this study were to systematically review and investigate the association between positive affect (PA) and pain severity among adults with CNCP. Databases that were searched included MEDLINE (PubMed), PsycINFO, CINAHL, ProQuest Dissertations and Theses, OLASTER, Open Grey, and PsyArXiv (inception to July 23, 2019). We analyzed studies that: (1) used observational, experimental, or intervention study designs; (2) enrolled individuals with CNCP (pain ≥ 12 weeks); and (3) reported full quantitative results on outcomes. Two researchers independently screened articles, extracted data, and assessed the risk of bias. The main meta-analysis was followed by subgroup analyses. All analyses were performed using random-effects models. Formal tests for heterogeneity (Q-statistic; I) and publication bias (p-curve and p-uniform*) were performed. We meta-analyzed 29 studies with 3521 participants. Results demonstrated that PA inversely impacts pain severity in people with CNCP (r = -0.23). Subgroup analyses showed a significant effect for gender and marginally significant effects for age in studies that adjusted for NA. On average, effect sizes for observational studies were larger in studies with a higher proportion of female respondents and in studies that did not adjust for NA. Finally, larger effect sizes were found in intervention studies with older compared with younger samples.

Improving Quality of Life in Hematopoietic Stem Cell Transplantation Survivors Through a Positive Psychology Intervention

Despite advances in transplantation medicine, psychological distress and quality of life and functional deficits continue to compromise survivorship after hematopoietic stem cell transplantation (HSCT). With increasing numbers of HSCT survivors, supportive oncology interventions that target health-related outcomes in HSCT survivorship are needed. Here we aimed to test the feasibility and acceptability of a group format phone-delivered positive psychology (PP) intervention in HSCT survivors. This is a one-arm pilot study design that adapted and tested an individual PP intervention used in cardiac disease to a phone-delivered group-based program for HSCT survivors who were .4 to 39 years post-transplantation. All participants received an 8-session weekly PP intervention. We assessed feasibility by the enrollment and intervention completion rates. We examined acceptability on a 10-point Likert scale of ease and utility. Unstructured qualitative interviews were used to obtain participant feedback on the intervention for future application in a larger trial. Self-reported assessments on psychological, functional, and quality of life outcomes were administered at baseline and at follow-up (the end of the intervention). Of 64 eligible participants, 29 (45%) enrolled in the study. For the main aim of intervention feasibility and acceptability, participants completed 96% of all PP sessions and rated the ease (7.6 ± 1.7) and utility (8.1 ± 1.1) of sessions highly. Of the self-reported assessments obtained, the PP intervention resulted in improvements in the resilience scale (mean difference, 2.4 ± 5.4; P = .03). From unstructured qualitative interviews, participants reported the PP exercises and intervention helped them to focus on positive emotions and the group format fostered a sense of community and social support. An 8-week phone-delivered group format PP intervention is feasible and acceptable in HSCT survivors. The piloted intervention could be tested with minor modifications in a randomized study to definitively examine the impact of the group format PP intervention on health-related outcomes.

The Effects of a Digital Well-Being Intervention on Patients With Chronic Conditions: Observational Study

BACKGROUND

Chronic conditions account for 75% of health care costs, and the impact of chronic illness is expected to grow over time. Although subjective well-being predicts better health outcomes, people with chronic conditions tend to report lower well-being. Improving well-being might mitigate costs associated with chronic illness; however, existing interventions can be difficult to access and draw from a single theoretical approach. Happify, a digital well-being intervention program drawing from multiple theoretical traditions to target well-being, has already been established as an efficacious means of improving well-being in both distressed and nondistressed users.

OBJECTIVE

This study aimed to compare change in well-being over time after using Happify for users with and without a chronic condition.

METHODS

Data were obtained from Happify users, a publicly available digital well-being program accessible via website or mobile phone app. Users work on tracks addressing a specific issue (eg, conquering negative thoughts) composed of games and activities based on positive psychology, cognitive behavioral therapy, and mindfulness principles. The sample included 821 users receiving at least 6 weeks' exposure to Happify (ranging from 42 to 179 days) who met other inclusion criteria. As part of a baseline questionnaire, respondents reported demographic information (age and gender) and whether they had any of the prespecified chronic conditions: arthritis, diabetes, insomnia, multiple sclerosis, chronic pain, psoriasis, eczema, or some other condition (450 reported a chronic condition, whereas 371 did not). Subjective well-being was assessed with the Happify Scale, a 9-item measure of positive emotionality and life satisfaction. To evaluate changes in well-being over time, a mixed effects linear regression model was fit for subjective well-being, controlling for demographics and platform usage.

RESULTS

At baseline, users with a chronic condition had significantly lower subjective well-being (mean 38.34, SD 17.40) than users without a chronic condition (mean 43.65, SD 19.13). However, change trajectories for users with or without a chronic condition were not significantly different; both groups experienced equivalent improvements in well-being. We also found an effect for time from baseline (b=0.071; SE=0.010; P<.01) and number of activities completed (b=0.03; SE=0.009; P<.01), and a 2-way interaction between number of activities completed and time from baseline (b=0.0002; SE=0.00006; P<.01), such that completing more activities and doing so over increasingly longer periods produced improved well-being scores.

CONCLUSIONS

Data from this study support the conclusion that users with a chronic condition experienced significant improvement over time. Despite reporting lower subjective well-being on the whole, their change trajectory while using Happify was equivalent to those without a chronic condition. Consistent with past research, users who completed more activities over a longer period showed the most improvement. In short, the presence of a chronic condition did not prevent users from showing improved well-being when using Happify.

Recent advances in understanding the phenotypes of osteoarthritis

Recent research in the field of osteoarthritis (OA) has focused on understanding the underlying molecular and clinical phenotypes of the disease. This narrative review article focuses on recent advances in our understanding of the phenotypes of OA and proposes that the disease represents a diversity of clinical phenotypes that are underpinned by a number of molecular mechanisms, which may be shared by several phenotypes and targeted more specifically for therapeutic purposes. The clinical phenotypes of OA supposedly have different underlying etiologies and pathogenic pathways and they progress at different rates. Large OA population cohorts consist of a majority of patients whose disease progresses slowly and a minority of individuals whose disease may progress faster. The ability to identify the people with relatively rapidly progressing OA can transform clinical trials and enhance their efficiency. The identification, characterization, and classification of molecular phenotypes of rapidly progressing OA, which represent patients who may benefit most from intervention, could potentially serve as the basis for precision medicine for this disabling condition. Imaging and biochemical markers (biomarkers) are important diagnostic and research tools that can assist with this challenge.

Multisystem Resiliency as a Predictor of Physical and Psychological Functioning in Older Adults With Chronic Low Back Pain

Evidence supports the benefits of resilience among older adults with chronic pain. While numerous factors confer resilience, research has largely examined these measures in isolation, despite evidence of their synergistic effects. Conceptualizing resilience from a multisystem perspective may provide a deeper understanding of adaptive functioning in pain. Sixty adults (ages 60+ years) with chronic low back pain completed measures of physical function, pain intensity, disability, and a performance-based task assessing back-related physical functioning and movement-evoked pain (MEP). Depressive symptoms, quality of life, and general resilience were also evaluated. To examine multisystem resiliency, principal components analysis (PCA) was conducted to create composite domains for psychological (positive affect, hope, positive well-being, optimism), health (waist–hip ratio, body mass index, medical comorbidities), and social (emotional, instrumental, informational support) functioning measures, followed by cluster analysis to identify participant subgroups based upon composites. Results yielded four clusters: Cluster 1 (high levels of functioning across psychological, health, and social support domains); Cluster 2 (optimal health and low psychosocial functioning); Cluster 3 (high psychological function, moderate-to-high social support, and poorer health); and Cluster 4 (low levels of functioning across the three domains). Controlling for sociodemographic characteristics, individuals with a more resilient phenotype (Cluster 1) exhibited lower levels of disability, higher quality of life and psychological functioning, and greater functional performance when compared to those with a lower degree of personal resources (Cluster 4). No significant cluster differences emerged in self-reported pain intensity or MEP. These findings signify the presence of resiliency profiles based upon psychological, social, and health-related functioning. Further examination of the additive effects of multiple adaptive behaviors and resources may improve our understanding of resilience in the context of pain, informing novel interventions for older adults.

The Role of Pets in Supporting Cognitive-Behavioral Chronic Pain Self-Management: Perspectives of Older Adults

Cognitive-behavioral self-management strategies are recommended for older adults with chronic pain. The goal of this study was to explore how pet ownership promotes use of these strategies in everyday life. We conducted four focus groups (N = 25) with dog and cat owners aged ≥70 years with persistent pain. Participants described how their pets affect their daily routines and health, including pain and its management. We analyzed transcripts for salient themes, categorizing them according to their alignment with recommended pain self-management strategies: Mood Management (e.g., increases positive affect), Relaxation/Distraction (e.g., soothing presence), Physical Activity (e.g., dog-walking), Behavioral Activation (e.g., motivates activity even when pain present), Social Activation (e.g., facilitates socializing), and Sleep (e.g., encourages routine). Some participants described negative impacts of pet ownership. Having pets can facilitate behaviors and thoughts that may enhance coping with pain. Testing formal ways of leveraging pets' role may expand nonpharmacological options for chronic pain management.

Optimizing resilience in orofacial pain: a randomized controlled pilot study on hope

Introduction:

Over recent years, there has been growing interest in the role of positive, psychological resources that promote resilience and optimal functioning in chronic pain. Although multiple factors comprise resilience, hope is a strength-based motivational state known to contribute to positive psychosocial adjustment and adaptive pain coping. Emerging evidence supports the viability of therapeutic approaches that foster resilience; however, interventions designed to target hope in the context of pain have been remarkably understudied.

Objectives:

The objectives of this pilot study were to test the feasibility and preliminary efficacy of a resilience-oriented hope intervention for clinical pain, as well as psychosocial outcomes and experimental pain sensitivity in individuals with orofacial pain.

Methods:

Twenty-nine participants with temporomandibular disorder were randomized to a 3-session intervention intended to increase hope or a control intervention (EDU) involving education about pain and stress. Before and after the intervention, participants attended 2 laboratory sessions whereby they completed psychosocial questionnaires and sensitivity to heat, cold, and pressure pain was assessed. Hope was measured using the Adult State Hope Scale.

Results:

Compared with EDU, the Hope group exhibited an increase in state hope, lower heat pain sensitivity, higher pressure pain thresholds at the temporomandibular joint, and reductions in pain catastrophizing.

Conclusion:

Although preliminary, results suggest that a resilience-based hope intervention may be beneficial in reducing pain sensitivity and catastrophizing and could serve as a target for pain management.

Race/Ethnicity Moderates the Association Between Psychosocial Resilience and Movement-Evoked Pain in Knee Osteoarthritis

Objective

Racial/ethnic disparities in pain are well‐recognized, with non‐Hispanic blacks (NHBs) experiencing greater pain severity and pain‐related disability than non‐Hispanic whites (NHWs). Although numerous risk factors are posited as contributors to these disparities, there is limited research addressing how resilience differentially influences pain and functioning across race/ethnicity. Therefore, this study examined associations between measures of psychosocial resilience, clinical pain, and functional performance among adults with knee osteoarthritis (OA), and assessed the moderating role of race/ethnicity on these relationships.

Methods

In a secondary analysis of the Understanding Pain and Limitations in Osteoarthritic Disease (UPLOAD‐2) study, 201 individuals with knee OA (NHB = 105, NHW = 96) completed measures of resilience (ie, trait resilience, optimism, positive well‐being, social support, positive affect) and clinical pain, as well as a performance‐based measure assessing lower‐extremity function and movement‐evoked pain.

Results

Bivariate analyses showed that higher levels of psychosocial resilience were associated with lower clinical pain and disability and more optimal physical functioning. NHBs reported greater pain and disability, poorer lower‐extremity function, and higher movement‐evoked pain compared with NHWs; however, measures of psychosocial resilience were similar across race/ethnicity. In moderation analyses, higher optimism and positive well‐being were protective against movement‐evoked pain in NHBs, whereas higher levels of positive affect were associated with greater movement‐evoked pain in NHWs.

Conclusion

Our findings underscore the importance of psychosocial resilience on OA‐related pain and function and highlight the influence of race/ethnicity on the resilience‐pain relationship. Treatments aimed at targeting resilience may help mitigate racial/ethnic disparities in pain.

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.

Positive affect skills may improve pain management in people with HIV

Non-opioid pain management strategies are critically needed for people with HIV. We therefore conducted a secondary analysis of pain-related outcomes in a randomized controlled trial of a positive affect skills intervention for adults newly diagnosed with HIV (N = 159). Results suggest that, even if pain prevalence rises, positive affect skills may reduce pain interference and prevent increased use of opioid analgesics by people living with HIV. Future research should replicate and extend these findings by conducting trials that are specifically designed to target pain outcomes.

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.
