Beyond pain intensity and catastrophizing: The association between self-enhancing humour style and the adaptation of individuals with chronic pain

VULNERABILITY FACTORS, ADJUSTMENT, AND OPIOID MISUSE IN CHRONIC NON-CANCER PAIN INDIVIDUALS

There are several person variables that pre-date injury or pain onset that increase the probability of maladjustment to pain and opioid misuse. The aim of this study was to evaluate the role of two diathesis variables (impulsiveness and anxiety sensitivity) in the adjustment of individuals with chronic noncancer pain and in the opioid misuse. The sample comprised 187 individuals with chronic noncancer pain. The hypothetical model was tested using correlation and structural equation modelling analyses. The results show a significant association between impulsiveness and anxiety sensitivity and all the maladjustment variables, and between impulsiveness and anxiety sensitivity and opioid misuse and craving. However, although the correlation analysis showed a significant association between adjustment to pain and opioid misuse, the SEM analysis showed a nonsignificant association between them (as latent variables). The findings support the hypothesis that both impulsiveness and anxiety sensitivity are vulnerability factors for maladaptive adjustment to chronic pain and opioid misuse. PERSPECTIVE: This article adds to the empirical literature by including anxiety sensitivity and impulsiveness as antecedent variables in a model of dual vulnerability to chronic pain maladjustment and to opioid misuse. The findings suggest the potential utility of assessing both factors in individuals in the first stages of chronic pain.

When It Hurts, a Positive Attitude May Help. The Moderating Effect of Positive Affect on the Relationship Between Walking, Depression, and Symptoms in Women with Fibromyalgia

BACKGROUND

Increased exercise is a marker of health in fibromyalgia (FM). However, patients frequently avoid physical activity as a way of minimizing the pain they feel. This deprives them of opportunities to obtain positive reinforcement, increasing functional impact.

AIMS

This study examines the mediating role of depressive symptoms between walking (as physical exercise), functional impact, and pain, at different levels of positive affect (PA) among women with fibromyalgia.

DESIGN

Cross-sectional correlational study.

SETTINGS

Mutual aid associations for fibromyalgia in Spain.

PARTICIPANTS

231 women diagnosed with FM.

METHODS

Moderate mediation analyses were conducted using PROCESS.

RESULTS

First, a simple mediation model showed that depression mediated the effect of walking on functional impact, but not on pain. Additionally, the moderated mediated model showed that this effect was significant at medium and high levels of PA, but not when levels of PA were low.

CONCLUSIONS

Provision of resources focused on positive affect seem to increase the positive effects of walking on functional impact through the reduction of depressive symptoms. Nurses can improve adherence of patients with FM to walking behavior through increasing positive affect.

The Influence of the Fear of Negative Evaluation on Activity Avoidance in Fibromyalgia: Exploring Pain Acceptance and Positive Affect as Resilience Variables

To examine the mediating role of pain acceptance (PAcc) between fear of negative evaluation (FNE) and activity avoidance (AV) at different levels of positive affect (PA) (moderator) among women diagnosed with fibromyalgia (FM) (moderate mediation model). This study was cross-sectional in design. A convenience sample of women with FM (n = 231) completed measures of pain severity, FNE, PAcc, AV, and PA. A simple mediation model and a moderate mediation model was constructed and analyzed using the SPSS macro-PROCESS. First, PAcc mediated the effect of FNE on AV (β = .02, SE = 0.008; [95% CI [0.0075, 0.0394]). Second, a mediated effect of PAcc between FNE and AV moderated by PA at medium and high levels of PA were found (m: 0.23; β = -.22, p = .0006; h: 9.59; β = -.34, p = .0002. Future work should seek to validate study findings in diverse samples of FM patients. Additionally, future work should explore how FM self-management interventions that include PAcc can promote increased activity among women suffering from FM with medium to high levels of PA.

Patient-to-Patient Interactions During the Pain Management Programme: The Role of Humor and Venting in Building a Socially Supportive Community

Objectives

Social support is most positively perceived when there is an optimal match between a patient's need for communication and the purpose of their interaction. Maladaptive communication patterns may inhibit social bonding or mutual support, negatively impacting clinical outcomes. This study aimed to identify how people with chronic pain naturalistically converse together about their pain in the context of a Pain Management Programme (PMP).

Methods

Seven participants (4 females; 3 males) with ongoing chronic pain who were attending a PMP in a regional hospital in the United Kingdom were audio/video recorded during breaks in their PMP. Interactions were transcribed using Jeffersonian Transcription and analyzed using Conversation Analysis.

Results

Two conversational mechanisms were identified: (1) Conversational humor; and (2) A venting cycle. Participants used their pain-related experiences construct a motive for a joke, then proceeded to deliver the joke, which initiated a joke return from observers. The sequence was completed by a collaborative punchline. In the venting cycle, an initial complaint was escalated by the sharing of comparable experiences, after which the vent was concluded through a joke punchline, acting as a pivot to move the conversation forwards, terminating the venting.

Conclusions

Humorous interpersonal interactions about chronic pain provided a forum for social support-building within the PMP. Humor was affiliative and built social collaboration, helping individuals to together make sense of their pain in a prosocial atmosphere, approaching pain-related experiences with levity. Patient-to-patient interactions within the PMP were strongly prosocial and inclusive, potentially facilitating enhanced PMP clinical outcomes through collaboration.

Understanding Emotion Regulation and Humor Styles in Individuals with Callous-Unemotional Traits and Alexithymic Traits

Alexithymia is a personality trait which is characterized by impairments in identifying and describing emotions. Both psychopathic and alexithymic personality traits have been associated with impairments in emotion processing. This study aims to clarify the conceptual overlap between psychopathic traits (focusing on callous-unemotional traits) and alexithymic traits, with emotion regulation strategies and humor styles using a community sample. A battery of self-report measures was distributed through an online platform to 538 male and female participants between the ages of 18 to 65. Hierarchal linear regression analyses demonstrated that emotion regulation strategies were the strongest predictors and accounted for the largest variance of callous-unemotional traits and alexithymic traits. More specifically, expressive suppression arose as a positive predictor while cognitive reappraisal arose as a negative predictor for both personality traits. Aggressive humor (maladaptive) arose as a positive predictor while self-defeating humor (maladaptive) and affiliative humor (adaptive) arose as negative predictors for callous-unemotional traits. In contrast, self-defeating humor arose as a positive predictor for alexithymic traits while affiliative humor and self-enhancing humor arose as negative predictors. Findings indicate that there are similarities and differences between these personality traits. The implications regarding tailoring interventions that target specific deficits associated with each personality trait are discussed.

Development of the Pain Responses Scale: A measure informed by the BIS-BAS model of pain

BACKGROUND

The behavioural inhibition system and activation system (BIS-BAS) model of pain focusses on two clusters of responses to pain-escape/avoidance (BIS) and approach (BAS) behaviours. While the BIS-BAS model emphasizes active responses to pain, deactivation responses such as despondence and relaxation are also common. This study sought to develop self-report scales assessing cognitive, behavioural intentions and affective responses to pain consistent with this extended BIS-BAS framework. We also sought to develop short-forms of the emerging scales.

METHODS

Confirmatory factor analysis was performed to derive scales from a large item pool administered to a community sample with heterogeneous chronic pain (N = 476).

RESULTS

The items resulted in 16 scales assessing Thoughts, Affective responses, Behavioural Intentions and Valence-Associated Thoughts, which loaded on to the four theorized types of pain responses-Escape, Approach, Despondence and Relaxation-with the four emerging short-form scales assessing these overarching factors. The internal consistency reliabilities of the long-forms generally ranged from good to excellent (αs ≥ 0.83), with the exception of the Relaxation-Behavioural Intentions scale (α = 0.64). The four short-forms demonstrated at least adequate internal consistency reliability (αs ≥ 0.79). An initial test of the construct validity of the scales in relation to pain-related outcomes is also reported.

CONCLUSIONS

We anticipate that the Pain Responses Scale (PRS) developed from this research will be useful for assessing mechanisms targeted by many psychosocial pain treatments and will provide a nuanced understanding of the shared versus specific nature of these mechanisms.

SIGNIFICANCE

The Pain Responses Scale emerging from this research assesses four theorized, overarching responses to pain: Escape, Approach, Giving Up and Relaxation. This measure will afford the capacity to test a reconceptualized BIS-BAS model of pain and inform treatments that are adapted based on this framework.

Evaluation of a Humor Training for Patients with Chronic Pain: A Randomized Clinical Trial

Background

Humor and laughter are positively associated with psychological as well as with physical well-being. As there is little research examining to what extent patients suffering from chronic pain could benefit from a humor intervention, the goal of this study was to develop a pain-specific humor training and to evaluate its feasibility and effectiveness as component of regular, multimodal pain therapy.

Patients and Methods

Patients from inpatient treatment groups for chronic pain in a German hospital were randomly assigned to the training group (final n = 62) and the control group (final n = 65). The training consisted of four sessions that were implemented in the usual therapy throughout two weeks. Outcomes were divided into primary (perceived current pain intensity and depression) and secondary ones (quality of life impairment by pain, cheerfulness, and self-enhancing humor) and were assessed prior to and after intervention.

Results

Results showed improvements in all outcomes for both groups. For primary outcomes, a trend for a greater reduction in current pain intensity was found for the training group compared to the control group (p = 0.060, η²_p = 0.02), as well as, for secondary outcomes, a trend for greater reduction of quality of life impairment by pain (p = 0.079, η²_p = 0.02) and a trend for greater increase in self-enhancing humor (p = 0.086, η²_p = 0.02). Depression and cheerfulness remained unaffected. Feedback indicated feasibility of the training within multimodal therapy, showing overall acceptance as well as providing specific suggestions for improvement.

Conclusion

As the first study evaluating a specific humor training for patients with chronic pain within a randomized controlled trial, its results are promising regarding an additional contribution that humor interventions can make towards multimodal pain therapy.

The Silhouettes Fatigue Scale: a validity study with individuals with physical disabilities and chronic pain

PURPOSE

Fatigue is known to interfere with function in individuals with physical disabilities. In order to monitor changes in fatigue over time and evaluate the efficacy of treatments, psychometrically sound measures of fatigue are needed. The aim of this work was to evaluate the validity of the Silhouettes Fatigue Scale with English instructions (SFS-EN) in a sample of adults with physical disabilities living in the USA.

METHODS

Individuals with medical conditions associated with physical disabilities responded to an online survey that included the SFS-EN as well as another validated measure of fatigue (PROMIS short form-4a Fatigue Scale), and measures of pain intensity and pain catastrophizing.

RESULTS

523 individuals participated (mean age = 59.1 years; SD = 11.4). Most participants were Caucasian (89%), women (59%) and unemployed (71%). Results showed strong positive correlations between both measures of fatigue, supporting the convergent validity of the SFS-EN. In addition, the magnitude of this association was significantly greater than the association between the scores of the SFS-EN and the measures of pain intensity and pain catastrophizing, supporting the former's discriminant validity.

CONCLUSIONS

The findings extend previous results supporting the SFS as a brief, easy to administer and understand, and valid measure of fatigue.IMPLICATIONS FOR REHABILITATIONFatigue is common in adults with physical disabilities and chronic pain.The Silhouettes Fatigue Scale (SFS) is a new single-item measure of general fatigue.Findings show that the SFS with English instructions (SFS-EN) is an easy to understand measure.Results support the convergent and discriminant validity of the SFS-EN score in adults with physical disabilities and chronic pain.

The Impairment and Functioning Inventory Revised-English version: A validation study in individuals with disabilities and bothersome pain

BACKGROUND

Despite the relevance of daily function in individuals with chronic pain, few questionnaires have been designed to assess this domain in individuals with musculoskeletal pain. In addition, the Impairment and Functioning Inventory-Revised (IFI-R) is the only instrument that assesses perceived decreases in levels of daily activity after the onset of pain.

OBJECTIVE

To evaluate the psychometric properties of the English version of the IFI-R.

DESIGN

Cross-sectional study.

SETTING

A database of individuals with medical conditions commonly associated with chronic pain maintained by the University of Washington.

PATIENTS

A total of 470 individuals with chronic pain.

METHODS

Factorial validity was analyzed by conducting a confirmatory factor analysis via structural equation modeling. Internal consistency was evaluated by calculating Cronbach's α coefficients. Convergent validity was assessed by calculating Pearson correlation coefficients between the two scales of the IFI-R and the Patient Reported Outcome Measurement Information System (PROMIS) Pain Interference Scale. Criterion validity was analyzed by regression analysis via structural equation modeling.

MAIN OUTCOME MEASURES

The English version of the IFI-R (IFI-R-EV) for individuals with chronic pain.

RESULTS

The IFI-R-EV consists of 30 items with two related subscales: The Daily Function subscale (α = .86). and the Impairment subscale (α = .89). A significant correlation was found between these subscales and a measure of pain interference (r's = - .33, and .35 respectively; p's < .01). We also found statistically significant associations (p < .05) between daily function and depression (β = -.14) and pain intensity (β = -.13), between impairment and depression (β = .14) and pain intensity (β = .16), and between daily function and pain acceptance (β = .14).

CONCLUSIONS

The findings indicate that the IFI-R-EV provides valid and reliable measures of daily function and impairment in English-speaking individuals with a disability and chronic pain. These results are consistent with those obtained with the Spanish version.
