Why and when social support predicts older adults' pain-related disability: a longitudinal study

Navigating the biopsychosocial landscape: A systematic review on the association between social support and chronic pain

The biopsychosocial model is widely used to explain chronic pain conditions. Yet, the role of social aspects including social support is not clear. Literature on social support and chronic pain is still sparse and results inconsistent. The aim of this review is to evaluate the association between social support and different aspects of chronic pain such as pain intensity, pain interference, quality of life, depression and anxiety. We performed a search on Pubmed, Embase, PsycINFO, Cochrane Library, Scopus and CINAHL database entries between January 1, 1980 and May 7, 2024. Two independent investigators selected all longitudinal (prospective or retrospective) and cross-sectional studies in adult populations investigating the effect of perceived social support, social support satisfaction or spousal responses on different aspects of chronic pain (persistent or recurrent pain lasting longer than 3 months). Out of 11,908 queried results, 67 studies met our inclusion criteria. After assessing for risk of bias (adapted version of the "JBI Critical Appraisal Checklist for Analytical Cross-Sectional Studies") and quality of evidence (adapted version of the quality assessment tool of Hawker and al.), 35 studies were included in the final analysis. We found that perceived social support was positively associated with quality of life and negatively associated with depression. Social support satisfaction was negatively associated with depression. Spousal responses were positively associated with pain intensity, pain interference and depression. This review found that, in patients with chronic pain, social support is mainly associated with psychological variables. However, most studies were cross-sectional, and most analyses were correlations. There is a need for higher quality longitudinal studies. The type of social support studied should be clearly defined in every study.

The Relationship of Pain Intensity, Perceived Injustice, and Pain Catastrophizing to Heart Rate Variability In Naturally Occurring Acute Pain

OBJECTIVES

Behavioral factors of pain catastrophizing and perceived injustice are associated with pain intensity in chronic pain. Diminished heart rate variability (HRV) is also strongly associated with chronic pain. These factors have been less explored earlier in the pain experience and it is unclear whether they play a role in the transition from acute to chronic pain. The aim of this study was to determine the relationship between pain catastrophizing, perceived injustice, pain intensity, and HRV in naturally occurring acute pain.

MATERIALS AND METHODS

Ninety-seven patients were recruited from local outpatient physical therapy clinics. Seated HRV was captured on 94 patients via Polar chest strap while patients were taking a survey via iPad. In addition to sociodemographic data, the survey included the Pain Catastrophizing Scale (PCS), Injustice Experience Questionnaire (IEQ), and Numeric Pain Rating Scale (NPRS). The natural log of high-frequency power (lnHFP) HRV was used in the statistical analysis.

RESULTS

Multiple linear regression modeling revealed that lower pain catastrophizing, higher perceived injustice, and lower pain intensity were associated with lower HRV, and accounted for 11.4% of the variance in HRV.

DISCUSSION

While greater chronic pain intensity is associated with lower HRV, the relationship is reversed in the setting of acute pain. These findings highlight the need to better understand the unique factors that contribute to lower HRV in the acute phase.

Assessing pain in persons with opioid use disorder: Approaches, techniques and special considerations

Pain and opioid use disorder (OUD) are inextricably linked, as the former can be a risk factor for the development of the latter, and over a third of persons with OUD suffer concomitant chronic pain. Assessing pain among people with OUD is challenging, because ongoing opioid use brings changes in pain responses and most pain assessment tools have not been validated for this population. In this narrative review, we discuss the fundamentals of pain assessment for populations with OUD. First, we describe the biological, psychological and social aspects of the pain experience among people with OUD, as well as how opioid-related phenomena may contribute to the pain experience in this population. We then review methods to assess pain, including (1) traditional self-reported methods, such visual analogue scales and structured questionnaires; (2) behavioural observations and physiological indicators; (3) and laboratory-based approaches, such as quantitative sensory testing. These methods are considered from a perspective that encompasses both pain and OUD. Finally, we discuss strategies for improving pain assessment in persons with OUD and implications for future research, including educational strategies for multidisciplinary teams. We highlight the substantial gaps that persist in this literature, particularly regarding the applicability of current pain assessment methods to persons with OUD, as well as the generalizability of the existing results from adjacent populations on chronic opioid therapy but without OUD. As research linking pain and OUD evolves, considering the needs of diverse populations with complex psychosocial backgrounds, clinicians will be better equipped to reduce these gaps.

Influencing factors of kinesiophobia in knee arthroplasty patients under the social cognitive theory: A structural equation model

OBJECTIVE

To analyze the path relationships among influencing factors for kinesiophobia in knee arthroplasty patients through a structural equation model.

BACKGROUND

The occurrence of kinesiophobia significantly impacts the rehabilitation process of knee arthroplasty patients. However, there is still a need to determine factors that contribute to reducing kinesiophobia.

DESIGN

A cross-sectional study was conducted and reported following the STROBE guideline.

METHODS

Between February 2022 to October 2022, 162 total knee arthroplasty (TKA) patients and 81 unicompartmental knee arthroplasty (UKA) patients completed a survey. A structural equation modeling (SEM) approach was utilized to analyze the relationships between kinesiophobia and influencing factors (social support, pain resilience, and rehabilitation self-efficacy). Furthermore, multi-group SEM analysis was conducted to examine whether the model equally fitted patients in different types of knee arthroplasty.

RESULTS

The direct negative effects of rehabilitation self-efficacy (β = -0.535) and pain resilience (β = -0.293) on kinesiophobia were observed. The mediating effect (β = -0.183) of pain resilience and rehabilitation self-efficacy between social support and kinesiophobia was also significant. The SEM model achieved an acceptable model fit (χ2 = 35.656, RMSEA = 0.031, χ2/df = 1.230, GFI = 0.972, NFI = 0.982, IFI = 0.997, CFI = 0.996). In multicohort analysis, no significant differences were observed among knee arthroplasties (TKA, UKA) (Δχ2 = 4.213, p = 0.648).

CONCLUSIONS

Satisfactory social support enhances pain resilience and rehabilitation self-efficacy, so as to reduce kinesiophobia. Future interventions that directly target the assessment and management of kinesiophobia, available social support may help reduce kinesiophobia, and pain resilience and rehabilitation self-efficacy may be critical factors in managing kinesiophobia.

RELEVANCE TO CLINICAL PRACTICE

Reducing kinesiophobia in knee arthroplasty patients requires satisfactory social support, pain resilience, and rehabilitation self-efficacy. Therefore, healthcare organizations may implement initiatives to reduce kinesiophobia by taking these factors into account.

Is Social Support Associated With Clinical Outcomes in Adults With Nonspecific Chronic Low Back Pain? A Systematic Review

OBJECTIVES

Nonspecific chronic low back pain (NSCLBP) is associated with psychological and social factors such as social support. However, little research has focused on the latter. This article aimed to review the literature on the association between social support and clinical outcomes of patients with NSCLBP, particularly regarding differences in sex, gender, and types of social support.

METHODS

MEDLINE, EMBASE, Web of Science, PsycINFO, and CENTRAL were searched until April 19, 2024, without restrictions of time or language. Eligible articles were observational studies reporting measures of association between social support and clinical outcomes among adults with NSCLBP. Risk of bias was assessed using the QUIPS tool, and findings were analyzed qualitatively. This systematic review was registered on PROSPERO (CRD42022363210).

RESULTS

Of the 3528 identified studies, 11 were included in the review (1290 patients), showing a moderate to high risk of bias. Of the 5 studies showing a significant finding for pain, 4 reported a negative correlation (r=-0.18, -0.32, -0.35, -0.36) and 1 did not report any association index. Of the 6 studies showing a significant finding for disability, 2 reported a negative correlation (r=-0.29, -0.42), 2 reported a positive association (r=0.322; β=0.29), and 2 did not report any association index. No data was available for the investigated subgroups or secondary clinical outcomes.

DISCUSSION

Small associations were found between social support and clinical outcomes of individuals with NSCLBP. Further research is needed to establish its clinical relevance according to types of social support, sex, and gender.

A secondary analysis of three types of social support in relation to self-efficacy, disease impact, and depression in fibromyalgia

OBJECTIVE

Fibromyalgia (FM) is a chronic pain condition associated with depression. However, self-efficacy (belief in own ability to manage symptoms) and social support may be protective. This study tested three types of social support (emotional, tangible, and instrumental) for moderation of the mediating effect of self-efficacy on the relationship between FM impact and depression over time.

METHODS

Six hundred participants with FM were randomly assigned to no intervention, social support group, or combined self-management and social support. The Fibromyalgia Impact Questionnaire, Norbeck Social Support Questionnaire, FM-modified Arthritis Self-Efficacy Scale, and Center for Epidemiological Studies-Depression surveys were administered at baseline, 6, 12, and 18 months. There were no significant intervention effects on the variables of interest, however, participants' scores were used to assess four longitudinal models.

RESULTS

Self-efficacy showed mediation both between (b = 0.104, p < .001, 95% CI = [0.071, 0.137]) and within (b = 0.89, p < .001, 95% CI = [0.073, 0.106]) individuals. Only tangible support demonstrated moderation of the relationship between FM impact and self-efficacy, and only between individuals (b = 0.154, p = .022, 95% CI = [0.022, 0.287]).

CONCLUSION

The results indicated that self-efficacy attenuated a portion of the effect of FM impact on depression over time. Additionally, higher levels of tangible support (the belief that your social network can provide you with assistance) were related to weaker influence of FM impact on self-efficacy over time. These factors may be important targets for the prevention of depression in people with FM.

Assessing family social support for functional autonomy and dependence in pain: A psychometric study

Assessing family supportive responses to pain behaviors is paramount, as these may help or hinder chronic pain (CP) adjustment. Current self-report measures of pain-specific family supportive dynamics are scarce, covering a limited range of responses. To address this gap, this paper aimed at the psychometric validation of a (revised) novel measure - the Informal Social Support for Autonomy and Dependence in Pain Inventory (ISSADI-PAIN). Three-hundred and three adults participated in this study (53.3% women; M_age = 49.31), 53.5% with current CP, 20.1% with acute pain (AP) in the previous week and 26.4% with no current pain. All participants completed the revised ISSADI-PAIN. Participants reporting AP/CP in the previous week also filled out measures of pain coping/outcomes. Exploratory and confirmatory factor analyzes supported a 3-factor structure: Perceived Promotion of Dependence (PPD; 5 items; α = .82), Perceived Promotion of Autonomy-Emotional (PPA-Emot; 3 items; α = .78), PPA-instrumental (PPA-Inst; 3 items; α = .82). Higher PPD was associated with higher AP disability and less wellness-focused coping; higher PPA-Emot was associated with more wellness-focused CP coping; PPA-Inst was associated with better/worse AP/CP outcomes and more frequent use of wellness-focused CP coping. Men with AP reported more PPD than women. The revised ISSADI-PAIN is an innovative, valid, and reliable measure of relevant functions of pain-related social support, which may influence pain persistence and adaptation. PERSPECTIVE: This article presents a novel self-report measure (ISSADI-PAIN) that assesses family support for functional autonomy and dependence in pain contexts. This measure may contribute to further research on the complexities of family supportive dynamics surrounding individuals with AP/CP, clarifying their role on pain persistence and adaptation processes.

The Informal Social Support for Autonomy and Dependence in Pain Inventory Spanish version

Social support plays a crucial role in the quality of life of people with chronic pain. The Informal Social Support for Autonomy and Dependence in Pain Inventory assesses two functions of received social support: the promotion of autonomy and the promotion of dependence. The aim of this cross-sectional study was to adapt this instrument for its use in the Spanish population. The sample comprised 256 individuals with chronic pain. Participants were recruited through two local associations of people with fibromyalgia, a physiotherapy unit and a hospital pain unit. The data were collected in Spain between October 2018 and January 2020. The structure of the questionnaire was analysed using confirmatory factor analysis, average variance extracted, composite reliability and internal consistency indexes, and inter-correlations between the scales. The criterion-related validity of the instrument was analysed by investigating its relationship with pain intensity, positive and negative affect, daily functioning, activity impairment, wellbeing and satisfaction with life. The structure with the best fit had four related factors: emotional social support for the promotion of autonomy; instrumental social support for the promotion of autonomy; emotional social support for the promotion of dependence and instrumental social support for the promotion of dependence. The scales showed adequate internal consistency. An association was found between higher levels of instrumental social support for the promotion of dependence and higher levels of pain-related disability and decreased daily functioning. An association was also found between the promotion of autonomy and increased satisfaction with life. The Spanish version of the inventory shows appropriate psychometric properties. In the setting of disability prevention, this instrument is useful in assessing the support relationships between people with chronic pain and their relatives.

Relationship between social support, physical symptoms, and depression in women with breast cancer and pain

PURPOSE

Fatigue and pain are common among women with breast cancer, and often related to depressive symptoms. Social support may influence levels of fatigue, pain interference, and depressive symptoms. We tested a theory-based, structural model examining the relationship between social support (i.e., emotional and instrumental) and depressive symptoms via fatigue and pain interference in women with breast cancer.

METHODS

Women (N = 327) with stages I-III breast cancer were enrolled in a randomized trial investigating a behavioral pain intervention. Measures of social support, fatigue, pain interference, and depressive symptoms were completed at enrollment. Data were analyzed using structural equation modeling to test direct and indirect pathways relating social support, fatigue, pain interference, and depressive symptoms.

RESULTS

Our model evidenced good fit. Significant direct effects emerged linking higher levels of emotional support with lower levels of fatigue (β = -.30), pain interference (β = -.32), and depressive symptoms (β = -.31). More instrumental support was significantly associated with more depressive symptoms (β = .11), but not fatigue or pain interference. Higher levels of fatigue (β = .30) and pain interference (β = .34) were significantly related to higher levels of depressive symptoms. More emotional support related to less depressive symptoms via lower levels of fatigue (β = -.09) and pain interference (β = -.11).

CONCLUSION

Women reporting higher levels of emotional support endorsed fewer depressive symptoms, and that relationship was driven by lower levels of fatigue and pain interference. Our results highlight novel pathways that healthcare professionals can leverage to optimize social support topics in psychosocial interventions targeting breast cancer symptoms. This model should be replicated using longitudinal data.

The role of physical, cognitive and social factors in pain interference with activities of daily living among individuals with chronic cancer pain

OBJECTIVES

The aim of this study was to better understand the role that physical, cognitive and social factors play in pain interference with activities of daily living among individuals with cancer and chronic pain.

METHOD

In this cross-sectional study, interviews with 156 patients with chronic cancer pain were conducted across five tertiary level hospitals in the province of Tarragona (Spain). Participants were interviewed individually and provided information about the presence and characteristics of pain, fatigue, catastrophic thinking, social support and the impact of pain on their daily activities.

RESULTS

Pain intensity (β = 0.23, p = .003), fatigue (β = 0.26, p < .001) and pain catastrophising (β = 0.39, p < .001) were significantly and positively associated with pain interference in daily activities. Pain interference scores were not explained by social support (β = 0.12 p = .090) or socio-demographic factors (R²  = .005; p = .94).

CONCLUSION

This study provides important new findings regarding the association between physical, cognitive and social factors and function of individuals with cancer and chronic pain, thus supporting a biopsychosocial approach to the management of chronic pain in individuals with cancer.

The Effects of Partners' Helping Motivation on Chronic Pain Patients' Functioning Over Time

To understand when and why the provision of help by a partner of an individual with chronic pain (ICP) yields benefits, it is critical, according to self-determination theory, to consider the extent to which partners' helping responses are supportive of the basic psychological needs of the ICP, as well as the motivations underlying these helping responses. The present study (N = 141 couples), spanning 3 measurement moments over 6 months, investigated temporal associations between partners' helping motivation, ICPs' psychological needs, and ICPs' functioning across time (ie, well-being, psychological distress, and disability). Results showed that partners' autonomous or volitional helping motivation (time 1) predicted decreases in ICPs' need frustration (time 2) and ICPs' need frustration (time 2) predicted increases in ICPs' psychological distress (time 3). Further, ICPs' need satisfaction (time 2) predicted increases in well-being (time 3) and decreases in psychological distress (time 3). The link between need frustration and ICPs' well-being (time 1-time 2) was bidirectional, with both relating reciprocally to one another over time. Finally, the associations between ICPs' disability and both partners' helping motivation and ICPs' need-based experiences were nonsignificant. Implications for research and clinical practice are discussed. Perspective: Partners' helping motivations and ICPs' psychological needs seem to be important to consider when investigating the role of spousal responses, because they could (indirectly) predict changes in the well-being and psychological distress of ICPs over time.
