Pain-Specific Resilience in People Living With HIV and Chronic Pain: Beneficial Associations With Coping Strategies and Catastrophizing

Group Intervention Program to Facilitate Post-Traumatic Growth and Reduce Stigma in HIV

Background: Research on post-traumatic growth (PTG) and HIV is scarce and the relationship between PTG and stigma is controversial. Group psychotherapeutic interventions to facilitate PTG in clinical samples are effective but none exist to simultaneously decrease stigma in the HIV population. The main objective was to evaluate the effectiveness of an intervention in increasing PTG and decreasing stigma in HIV, as well as to explore relationships between the variables. Methods: Quasi-experimental design with a sample of 42 HIV-positive adults (M = 46.26, SD = 11.90). The experimental group (EG) was subjected to a 9-week group intervention. Instruments: CBI, PTGI-X, PSS-10, HIV stigma, emotional expression, HIV stress indicators, HIV literacy, and skills. Multiple linear regression analysis was performed to assess the relationship between the variables. Results: There was an increase in PTG and a significant decrease in stigma in all domains and subscales in the EG. Compared to the control group, stigma (t(42) = -3.040, p = 0.004) and negative self-image (W = -2.937, p = 0.003) were significant, showing the efficacy of the intervention. Discussion: The intervention demonstrated success in facilitating PTG, attesting that in order to increase PTG, personal strength, and spiritual change, it is necessary to reduce stigma and negative self-image. The research provides more information on group interventions for PTG in HIV, relationships between variables, and population-specific knowledge for professionals.

Finding a path in a methodological jungle: a qualitative research of resilience

Qualitative research provides an in-depth understanding of lived experiences. However, these experiences can be hard to apprehend by using just one method of data analysis. A good example is the experience of resilience. In this paper, the authors describe the chain of the decision-making process in the research of the construct of "resilience". s The authors justify the implications of a multi-method, pluralistic approach, and show how the triangulation of two or more qualitative methods and integration of several qualitative data analysis methods can improve a deeper understanding of the resilience among people with chronic pain. By combining the thematic analysis, narrative analysis, and critical incident technique, lived experiences can be seen from different perspectives.Therefore, the thematic analysis describes the content and answers to "what" regarding resilience, the narrative analysis describes the dynamics of resilience, and answers to "how", while the critical incident technique clarifies the most significant experience and the answers to "why" changes happen. This integrative approach could be used in the analysis of other psychological constructs and can serve as an example of how the rigour of qualitative research could be provided.

Cognitive-Affective-Behavioral Pathways Linking Adversity and Discrimination to Daily Pain in African-American Adults

The tendency to ruminate, magnify, and experience helplessness in the face of pain - known as pain catastrophizing - is a strong predictor of pain outcomes and is associated with adversity. The ability to maintain functioning despite adversity - referred to as resilience - also influences pain outcomes. Understanding the extent to which pain catastrophizing and resilience influence relations between adversity and daily pain in healthy African-American adults could improve pain risk assessment and mitigate racial disparities in the transition from acute to chronic pain. This study included 160 African-American adults (98 women). Outcome measures included daily pain intensity (sensory, affective) and pain impact on daily function (pain interference). Adversity measures included childhood trauma exposure, family adversity, chronic burden from recent stressors, and ongoing perceived stress. A measure of lifetime racial discrimination was also included. Composite scores were created to capture early-life adversity (childhood trauma, family adversity) versus recent-life adversity (perceived stress, chronic burden). Increased pain catastrophizing was correlated with increased adversity (early and recent), racial discrimination, pain intensity, and pain interference. Decreased pain resilience was correlated with increased recent-life adversity (not early-life adversity or racial discrimination) and correlated with increased pain intensity (not pain-related interference). Bootstrapped multiple mediation models revealed that relationships between all adversity/discrimination and pain outcomes were mediated by pain catastrophizing. Pain resilience, however, was not a significant mediator in these models. These findings highlight opportunities for early interventions to reduce cognitive-affective-behavioral risk factors for persisting daily pain among African-American adults with greater adversity exposure by targeting pain catastrophizing.

Brain system segregation and pain catastrophizing in chronic pain progression

Pain processing involves emotional and cognitive factors that can modify pain perception. Increasing evidence suggests that pain catastrophizing (PC) is implicated, through pain-related self-thoughts, in the maladaptive plastic changes related to the maintenance of chronic pain (CP). Functional magnetic resonance imaging (fMRI) studies have shown an association between CP and two main networks: default mode (DMN) and dorsoattentional (DAN). Brain system segregation degree (SyS), an fMRI framework used to quantify the extent to which functional networks are segregated from each other, is associated with cognitive abilities in both healthy individuals and neurological patients. We hypothesized that individuals suffering from CP would show worst health-related status compared to healthy individuals and that, within CP individuals, longitudinal changes in pain experience (pain intensity and affective interference), could be predicted by SyS and PC subdomains (rumination, magnification, and helplessness). To assess the longitudinal progression of CP, two pain surveys were taken before and after an in-person assessment (physical evaluation and fMRI). We first compared the sociodemographic, health-related, and SyS data in the whole sample (no pain and pain groups). Secondly, we ran linear regression and a moderation model only in the pain group, to see the predictive and moderator values of PC and SyS in pain progression. From our sample of 347 individuals (mean age = 53.84, 55.2% women), 133 responded to having CP, and 214 denied having CP. When comparing groups, results showed significant differences in health-related questionnaires, but no differences in SyS. Within the pain group, helplessness (β = 0.325; p = 0.003), higher DMN (β = 0.193; p = 0.037), and lower DAN segregation (β = 0.215; p = 0.014) were strongly associated with a worsening in pain experience over time. Moreover, helplessness moderated the association between DMN segregation and pain experience progression (p = 0.003). Our findings indicate that the efficient functioning of these networks and catastrophizing could be used as predictors of pain progression, bringing new light to the influence of the interplay between psychological aspects and brain networks. Consequently, approaches focusing on these factors could minimize the impact on daily life activities.

Mitochondrial reactivity following acute exposure to experimental pain testing in people with HIV and chronic pain

Background: Physical stressors can cause a physiological response that can contribute to an increase in mitochondrial dysfunction and Mitochondrial DNA damage (mtDNA damage). People living with HIV (PWH) are more likely to suffer from chronic pain and may be more susceptible to mitochondrial dysfunction following exposure to a stressor. We used Quantitative Sensory Testing (QST) as an acute painful stressor in order to investigate whether PWH with/without chronic pain show differential mitochondrial physiological responses. Methods: The current study included PWH with (n = 26), and without (n = 29), chronic pain. Participants completed a single session that lasted approximately 180 min, including QST. Blood was taken prior to and following the QST battery for assays measuring mtDNA damage, mtDNA copy number, and mtDNA damage-associated molecular pattern (DAMP) levels (i.e., ND1 and ND6). Results: We examined differences between those with and without pain on various indicators of mitochondrial reactivity following exposure to QST. However, only ND6 and mtDNA damage were shown to be statistically significant between pain groups. Conclusion: PWH with chronic pain showed greater mitochondrial reactivity to laboratory stressors. Consequently, PWH and chronic pain may be more susceptible to conditions in which mitochondrial damage/dysfunction play a central role, such as cognitive decline.

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.

Exploring prevention and management of secondary health conditions in people with spinal cord injury in South Africa

Background/Aims

Preventative care for people with spinal cord injury is neglected, even though secondary health conditions are prevalent among this group. There is limited information on preventative care for secondary health conditions among people with spinal cord injury. This study aimed to explore how people with spinal cord injury prevent and manage secondary health conditions.

Methods

A total of 17 individuals with spinal cord injury attending an outpatients clinic at a public rehabilitation hospital were interviewed face to face. All the interviews were transcribed verbatim and analysed using thematic content analysis.

Results

The participants used different strategies to prevent and manage secondary health conditions, such as medication, assistive devices, self-management, resilience coping strategies and therapeutic approaches. The participants found prevention of secondary health conditions ‘challenging’ and some of the strategies were ineffective.

Conclusions

Although many strategies are used by people with spinal cord injury to prevent and manage secondary health conditions, the experience is difficult. To minimise the occurrence and the consequence of secondary health conditions among people with spinal cord injury, health professionals must promote and support preventative care for secondary health conditions.

The Effect of Pain Resilience on Experimental Pain Experience Across Different Stimuli

OBJECTIVE

Pain resilience, one's ability to maintain behavioral engagement and adaptively regulate cognitions and emotions despite intense or prolonged pain, has been shown to protect against negative pain-related outcomes in experimental settings. A weakness of this research, and much of experimental pain research in general, has been the lack of rationale behind the selection of noxious stimuli, which can activate different nociceptive fibers. The present study sought to determine if the relationship between pain resilience and pain ratings differed across stimuli based on the stimulated nociceptors.

METHODS

Healthy undergraduate students (N = 100; mean [SD] age = 19.4 [1.2] years; 60% female) completed the Pain Resilience Scale and provided continuous pain ratings during exposure to three different tasks, each selected based on their ability to stimulate specific combinations of nociceptive fibers: pinprick (Aδ fibers), cold water immersion (Aδ and C fibers), and ischemic tourniquet (C fibers).

RESULTS

Participants with high pain resilience reported lower pain ratings over time during cold water immersion than did those with low pain resilience (F(1, 39) = 8.526, p = .006); however, there was no relationship between pain resilience and pain ratings during either of the pinprick or ischemic tourniquet stimuli.

CONCLUSIONS

This study provides further support for the use of multiple pain stimuli for pain assessment given their unique characteristics and concludes that outcome variables aside from pain ratings may provide additional insight into the role of resilience on pain adaptation.

Differences in Psychosocial Factors and Experimental Pain Sensitivity between Hispanics and non-Hispanic Whites from the U.S.-Mexico Border

PURPOSE

Research suggests that ethnicity is a predictor of pain-related outcomes; however, studies comparing the differences in experimental pain sensitivity between Hispanics and non-Hispanic Whites (NHW) are scarce. This study investigated these differences between Hispanics and NHW from the U.S- Mexico border.

METHODS

Fifty-eight healthy subjects completed the survey packet, which included a demographic and a psychosocial factors questionnaire. Participants underwent quantitative sensory testing which included heat pain threshold, heat pain tolerance, Suprathreshold Heat Pain Response (SHPR), and Conditioned Pain Modulation (CPM). SHPR was induced by repeated thermal stimuli in both thenar eminences. CPM was assessed using SHPR as the experimental stimulus, and cold pressor task as the conditioning stimulus.

RESULTS

Analyses showed significant differences in experimental pain measures believed to be representative of facilitatory pain processing including SHPR, and heat pain threshold, where Hispanics reported significantly higher pain ratings than NHW. Hispanics also reported higher levels of ethnic identity and acculturation. However, these factors were not significantly associated with experimental pain sensitivity.

CONCLUSION

The experimental pain sensitivity and psychosocial factors included in this study differed by ethnic group, where Hispanics reported significantly higher pain ratings, when compared to NHW. However, ethnic identity and acculturation were not associated with these pain-related outcomes. Overall, enhanced understanding by clinicians of pain sensitivity and disparities in the pain experience between ethnic groups allows for increased cultural sensitivity and can be used to optimize pain treatment on an individual-by-individual basis.

Insomnia severity and depressive symptoms in people living with HIV and chronic pain: associations with opioid use

Chronic pain commonly occurs in people living with HIV (PLWH). Many PLWH in the United States obtain opioids for chronic pain management. Whether insomnia severity and depressive symptoms are exacerbated by chronic pain and opioid use in PLWH remains to be determined. This study examined insomnia severity and depressive symptoms in 85 PLWH with chronic pain and 35 PLWH without chronic pain. Among PLWH with chronic pain, reported opioid use was examined in relation to insomnia severity and depressive symptoms. PLWH with chronic pain reported significantly greater insomnia severity (p = .033) and depressive symptoms (p = .025) than PLWH without chronic pain. Among PLWH with chronic pain who reported opioid use (n = 36), insomnia severity was greater compared to those who denied opioid use (n = 49), even after controlling for pain severity and number of comorbidities (p = .026). Greater pain severity was significantly associated with greater insomnia severity (p < .001) and depressive symptoms (p = .048) among PLWH with chronic pain who reported opioid use. These associations were not significant among those PLWH with chronic pain who denied opioid use. Findings suggest that PLWH with chronic pain are likely to experience poor sleep and depressed mood. Furthermore, poor sleep was associated with opioid use among PLWH with chronic pain.

Factors associated with current and severe pain among people living with HIV: results from a statewide sample

Background

People living with HIV (PLHIV) are more likely to suffer from pain compared to the general public. Pain often clusters with mental health symptoms and substance use. This study sought to evaluate mental health and substance use factors associated with any pain and severe pain intensities among PLHIV.

Methods

Data were derived from HIV+ adults (N = 733) recruited from community health centers across Florida who completed questionnaires regarding demographics, chronic pain, HIV clinical outcomes, mental health symptoms, and substance use information. Pain was assessed using the Brief Pain Inventory (BPI) short form. Multivariate logistic regression analysis was utilized to assess the relationship between selected covariates and pain.

Results

Approximately half (45.0%) of participants reported having any current pain while 16.1% reported severe pain. The odds of having any current pain were 2.49 (CI 95% 1.48, 4.18, p <  0.01) times greater among PLHIV reporting anxiety and 1.69 (CI 95% 1.11, 2.57, p = 0.01) times greater among PLHIV reporting PTSD compared to those without those factors. The odds of having severe pain were 2.03 (CI 95% 1.03, 4.01, p = 0.04) times greater among PLHIV reporting anxiety and 2.02 (CI 95% 1.26, 3.24, p <  0.01) times greater among female participants compared to PLHIV without those factors respectively. Factors including depression, alcohol consumption, and marijuana use were not statistically associated with any current pain nor with severe pain.

Conclusion

The relationship between pain and mental health is complex. Thus, future research is needed to determine if pain treatments may reduce mental health symptoms or if treatments can be targeted to address both issues simultaneously.

Pain resilience, pain catastrophizing, and executive functioning: performance on a short-term memory task during simultaneous ischemic pain

Among pain researchers there is a growing interest in the relationship between psychological resilience and pain experience. Whereas much of this work has focused on individual differences in pain perception or sensitivity, an equally important dimension of resilience is the capacity to persist with goal-directed activity despite experiencing pain. Consistent with this latter focus, the current study examined how pain resilience and pain catastrophizing combine to moderate the effects of ischemic pain on short-term memory task performance. Using a within-subjects design, 121 healthy participants completed four trials of a Corsi block-tapping task with pain exposure during the second and fourth trials. Results indicated that a combination of high pain resilience and low pain catastrophizing was associated with better task performance during the second pain exposure. These findings confirm existing evidence that resilience can moderate performance during pain, and offer new evidence that resilience and catastrophizing interact to shape this effect.

Pain Acceptance Partially Mediates the Relationship Between Perceived Injustice and Pain Outcomes Over 3 Months

OBJECTIVES

Perceived injustice is a maladaptive cognitive appraisal of pain or injury, characterized by attributions of blame, unfairness, severity of loss, and irreparability of loss. Research suggests that perceived injustice may negatively affect pain outcomes by inhibiting the development of pain-related acceptance. The current study aimed to extend cross-sectional research by testing whether pain acceptance mediates the effects of perceived injustice on pain-related outcomes longitudinally.

MATERIALS AND METHODS

Data was analyzed from a prospective study to examine the potential mediating role of pain acceptance on recovery 3 months after an episode of low back pain. Using Mechanical Turk, we recruited participants who experienced an episode of back pain within the preceding 2 weeks, 343 of whom completed measures of perceived injustice, pain acceptance, pain ratings, and quality of life at each of 3 timepoints (recruitment, 1 mo later, and 3 mo later). Path analyses were conducted to examine pain acceptance at 1 month as a potential mediator of the relationship between perceived injustice at recruitment and pain intensity, disability, and depressive symptoms at 3 months.

RESULTS

Results indicated that perceived injustice at recruitment was directly related to pain intensity, disability, and depressive symptoms 3 months later, and that pain acceptance partially mediated these relationships.

DISCUSSION

Although these findings provide further support for pain acceptance as a buffer for the deleterious effects of perceived injustice, they also highlight that adjunctive mechanisms should be investigated to provide more comprehensive clinical insight.
