Effects of COVID-19 Social Distancing Measures in Individuals with Chronic Pain Living in Spain in the Late Stages of the Lockdown

Economic Evaluation of Videoconference Group Acceptance and Commitment Therapy and Behavioral Activation Therapy for Depression Versus Usual Care Among Adults With Chronic Low Back Pain Plus Comorbid Depressive Symptoms

Chronic pain and depression are frequently comorbid conditions associated with significant health care and social costs. This study examined the cost-utility and cost-effectiveness of videoconference-based group forms of Acceptance and Commitment Therapy (ACT) and Behavioral Activation Therapy for Depression (BATD), as a complement to treatment-as-usual (TAU), for patients with chronic low back pain (CLBP) plus depressive symptoms, compared to TAU alone. A trial-based economic evaluation (n = 234) was conducted from a governmental and health care perspective with a time horizon of 12 months. Primary outcomes were the Brief Pain Inventory-Interference Scale (BPI-IS) and Quality Adjusted Life Year. Compared to TAU, ACT achieved a significant reduction in total costs (d = .47), and BATD achieved significant reductions in indirect (d = .61) and total costs (d = .63). Significant improvements in BPI-IS (d = .73 and d = .66, respectively) and Quality Adjusted Life Year scores (d = .46 and d = .28, respectively) were found in ACT and BATD compared to TAU. No significant differences in costs and outcomes were found between ACT and BATD. In the intention-to-treat analyses, from the governmental and health care perspective, no significant differences in cost reduction and incremental effects were identified in the comparison between ACT, BATD, and TAU. However, in the complete case analysis, significant incremental effects of ACT (∆BPI-IS = -1.57 and -1.39, respectively) and BATD (∆BPI-IS = -1.08 and -1.04, respectively) compared with TAU were observed. In the per-protocol analysis, only the significant incremental effects of ACT (∆BPI-IS = -1.68 and -1.43, respectively) compared to TAU were detected. In conclusion, ACT and BATD might be efficient options in the management of CLBP plus comorbid depression symptoms as compared to usual care. However, no clear difference was found in the comparison between the 2 active therapies regarding cost-effectiveness or cost-utility. PERSPECTIVE: The economic evaluation of psychological therapies for the management of complex conditions can be used in decision-making and resource allocation. This study provides evidence that ACT and BATD are more effective and involve a greater reduction in costs than usual care in the management of CLBP plus comorbid depressive symptoms.

The Silhouettes Fatigue Scale: further validation in Spanish-speaking university students and adults with chronic pain

PURPOSE

The aim of this study was to evaluate the psychometric properties of the Silhouettes Fatigue Scale (SFS) when used to assess fatigue in undergraduates and middle-aged adults with chronic pain.

MATERIALS AND METHODS

A total of 426 undergraduates and 207 middle-aged individuals with chronic pain participated in this study. Participants were asked to respond to a survey including the SFS as well as another validated measure of fatigue, questionnaires about pain catastrophizing and pain interference, and questions about pain (i.e., location, duration, and intensity). Convergent, discriminant, criterion and known-groups validity were evaluated.

RESULTS

Convergent validity was supported by a strong association between the two scales measuring fatigue. Discriminant validity was supported by stronger associations between the two fatigue scales scores compared to those between the SFS and pain catastrophizing scores. Criterion validity was supported by moderate associations between the SFS and measures of pain intensity and pain interference. Finally, known-groups validity was supported by significant differences in the SFS scores between students without chronic pain, students with chronic pain, and middle-aged individuals with chronic pain.

CONCLUSIONS

The findings support the validity of the SFS scores when used to assess fatigue in undergraduates and middle-aged adults with chronic pain.

Comparing the prevalence of chronic pain in school-aged children in the United States from 2019 to 2020: a nationally representative study examining differences associated with the COVID-19 pandemic

ABSTRACT

The coronavirus disease 19 (COVID-19) pandemic negatively affected children's health in the United States (US), with more severe disruption for marginalized groups. However, potential impact on pediatric chronic pain has not been assessed at the population level. This study aimed to (1) estimate differences in the US national prevalence of pediatric chronic pain during the first year of the COVID-19 pandemic (2020), relative to one year earlier (2019); (2) determine whether differences in prevalence varied across sociodemographic groups; and (3) explore changes in child, caregiver, and family factors associated with chronic pain prevalence. Using data of children 6 to 17 years from the National Survey of Children's Health 2019 and 2020 (n = 50,518), we compared weighted percentages of sample characteristics by year and conducted a series of directed-acyclic graph-informed survey-weighted Poisson regressions. The estimated national prevalence (95% CI) of pediatric chronic pain was 10.8% (9.9, 11.9%) in 2019, decreasing to 7.6% (6.9, 8.3%) in 2020. Contrary to hypotheses, the adjusted prevalence of chronic pain was 31% lower in 2020 than in 2019 (aPR = 0.69, 95% CI: 0.61, 0.79), adjusting for child age, sex, race or ethnicity, caregiver education, neighborhood park or playground, and census region. The 2019 to 2020 change in chronic pain prevalence was similar by age ( P = 0.34), sex ( P = 0.94), race or ethnicity ( P = 0.41), caregiver education ( P = 0.49), neighborhood park or playground ( P = 0.22), and census region ( P = 0.20). Exploratory analyses identified 3 potential contributors to the unexpected decrease in the national prevalence of pediatric chronic pain: lower prevalence of bullying, more frequent family meals, and higher family resilience.

Efficacy of Videoconference Group Acceptance and Commitment Therapy (ACT) and Behavioral Activation Therapy for Depression (BATD) for Chronic Low Back Pain (CLBP) Plus Comorbid Depressive Symptoms: A Randomized Controlled Trial (IMPACT Study)

This study examined the efficacy of adding a remote, synchronous, group, videoconference-based form of acceptance and commitment therapy (ACT) or behavioral activation therapy for depression (BATD) to treatment-as-usual (TAU) in 234 patients with chronic low back pain (CLBP) plus comorbid depressive symptoms. Participants were randomly assigned to ACT, BATD, or TAU. Compared to TAU, ACT produced a significant reduction in pain interference at posttreatment (d = .64) and at follow-up (d = .73). BATD was only superior to TAU at follow-up (d = .66). A significant reduction in pain catastrophizing was reported by patients assigned to ACT and BATD at posttreatment (d = .45 and d = .59, respectively) and at follow-up (d = .59, in both) compared to TAU. Stress was significantly reduced at posttreatment by ACT in comparison to TAU (d = .69). No significant between-group differences were found in depressive or anxiety symptoms. Clinically relevant number needed to treat (NNT) values for reduction in pain interference were obtained at posttreatment (ACT vs TAU = 4) and at follow-up (ACT vs TAU = 3; BATD vs TAU = 5). In both active therapies, improvements in pain interference at follow-up were significantly related to improvements at posttreatment in psychological flexibility. These findings suggest that new forms of cognitive-behavioral therapy are clinically useful in improving pain interference and pain catastrophizing. Further research on evidence-based change processes is required to understand the therapeutic needs of patients with chronic pain and comorbid conditions. TRIAL NUMBER: NCT04140838. PERSPECTIVE: Group videoconference-based ACT and BATD showed greater efficacy than TAU for reducing pain interference and pain catastrophizing in patients with CLBP plus clinically relevant depression. Psychological flexibility appeared to be the main contributor to treatment effects for both ACT and BATD.

Stronger association of perceived health with socio-economic inequality during COVID-19 pandemic than pre-pandemic era

Objective

The COVID-19 pandemic has changed peoples’ routine of daily living and posed major risks to global health and economy. Few studies have examined differential impacts of economic factors on health during pandemic compared to pre-pandemic. We aimed to compare the strength of associations between perceived health and socioeconomic position (household income, educational attainment, and employment) estimated before and during the pandemic.

Methods

Two waves of nationwide survey [on 2018(T1;n = 1200) and 2021(T2;n = 1000)] were done for 2200 community adults. A balanced distribution of confounders (demographics and socioeconomic position) were achieved across the T2 and T1 by use of the inverse probability of treatment weighting. Distributions of perceived health [= (excellent or very good)/(bad, fair, or good)] for physical-mental-social-spiritual subdomains were compared between T1 and T2. Odds of bad/fair/good health for demographics and socioeconomic position were obtained by univariate logistic regression. Adjusted odds (aOR) of bad/fair/good health in lower household income(< 3000 U.S. dollars/month) were retrieved using the multiple hierarchical logistic regression models of T1 and T2.

Results

Perceived health of excellent/very good at T2 was higher than T1 for physical(T1 = 36.05%, T2 = 39.13%; P = 0.04), but were lower for mental(T1 = 38.71%, T2 = 35.17%; P = 0.01) and social(T1 = 42.48%, T2 = 35.17%; P < 0.001) subdomains. Odds of bad/fair/good health were significantly increased at T2 than T1 for household income (physical-mental-social; all Ps < 0.001) and educational attainment (social; P = 0.04) but not for employment (all Ps > 0.05). AORs of bad/fair/good health in lower household income were stronger in T2 than T1, for mental [aOR (95% CI) = 2.15(1.68–2.77) in T2, 1.33(1.06–1.68) in T1; aOR difference = 0.82(P < 0.001)], physical [aOR (95% CI) = 2.64(2.05–3.41) in T2, 1.50(1.18–1.90) in T1; aOR difference = 1.14(P < 0.001)] and social [aOR (95% CI) = 2.15(1.68–2.77) in T2, 1.33(1.06–1.68) in T1; aOR difference = 0.35(P = 0.049)] subdomains.

Conclusions

Risks of perceived health worsening for mental and social subdomains in people with lower monthly household income or lower educational attainment became stronger during the COVID-19 pandemic compared to pre-pandemic era. In consideration of the prolonged pandemic as of mid-2022, policies aiming not only to sustain the monthly household income and compulsory education but also to actively enhance the perceived mental-social health status have to be executed and maintained.

The COVID-19 pandemic and its consequences for chronic pain: a narrative review

The COVID-19 pandemic transformed everyday life, but the implications were most impactful for vulnerable populations, including patients with chronic pain. Moreover, persistent pain is increasingly recognised as a key manifestation of long COVID. This narrative review explores the consequences of the COVID-19 pandemic for chronic pain. Publications were identified related to the COVID-19 pandemic influence on the burden of chronic pain, development of new-onset pain because of long COVID with proposed mechanisms and COVID-19 vaccines and pain interventions. Broadly, mechanisms underlying pain due to SARS-CoV-2 infection could be caused by 'systemic inflammatory-immune mechanisms', 'direct neuropathic mechanisms' or 'secondary mechanisms due to the viral infection or treatment'. Existing chronic pain populations were variably impacted and social determinants of health appeared to influence the degree of effect. SARS-CoV-2 infection increased the absolute numbers of patients with pain and headache. In the acute phase, headache as a presenting symptom predicted a milder course. New-onset chronic pain was reportedly common and likely involves multiple mechanisms; however, its prevalence decreases over time and symptoms appear to fluctuate. Patients requiring intensive support were particularly susceptible to long COVID symptoms. Some evidence suggests steroid exposure (often used for pain interventions) may affect vaccine efficacy, but there is no evidence of clinical repercussions to date. Although existing chronic pain management could help with symptomatic relief, there is a need to advance research focusing on mechanism-based treatments within the domain of multidisciplinary care.

The Role of Resilience, Happiness, and Social Support in the Psychological Function during the Late Stages of the Lockdown in Individuals with and without Chronic Pain

There is mounting evidence to suggest that individuals with chronic pain adjusted poorly to and were impacted negatively by social distancing measures during the lockdown. However, there is limited data on the factors that might protect against the negative effects associated with social distancing measures, as most research has been conducted in the general population and in the initial stages of the lockdown. The aim of this study was to improve the understanding of the role that resilience, happiness, and social support, all factors that are thought to have a protective role, played in the psychological function (measured as anxiety, depression, and stress) to the social distancing measures during the late stages of the lockdown in a sample of adults with and without chronic pain living in Spain. A group of 434 adults responded to an online survey and provided information on sociodemographic issues, which included measures of pain, perceived health and quality of life, depression, anxiety, stress, resilience, happiness, and social support. The data showed that individuals with chronic pain (N = 200; 46%) reported statistically significant worst psychological function, that is to say, they reported higher levels of anxiety, depression, and stress (all ps < 0.001). Resilience, social support, and happiness proved to be significant predictors of anxiety, depression, and stress, after controlling for the effects of age, gender, and chronic pain. Although the effect sizes were small to medium, they are consistent with the findings of other studies. The findings from this study provide important additional new information regarding the associations between resilience, happiness, and social support and the adjustment to the social distancing measures during the late stages of the lockdown. These findings can be used to develop programs to improve adjustment to and coping with the demands of social distancing measures.
