In search of the person in pain: A systematic review of conceptualization, assessment methods, and evidence for self and identity in chronic pain

Sexual Self Discrepancies, Sexual Satisfaction, and Relationship Satisfaction in a Cross-Sectional Sample of Women Who Experience Chronic Vaginal Pain during Sexual Intercourse

One out of three women may suffer from chronic vaginal pain during intercourse, a complex health issue that leads to lasting psychological, sexual, emotional, and relational difficulties even after initial relief. Women who experience this pain condition may compare their sexual selves to the societal norm of being pain-free. Comparisons that do not align with one's actual sexual self result in sexual self-discrepancies and may cause emotional distress. Sexual self-discrepancies may hinder sexual and relationship satisfaction for women who experience chronic vaginal pain during sexual intercourse. This mixed-method study examined the sexual self-discrepancies women reported and the degree to which their sexual self-discrepancies were related to their sexual and relationship satisfaction. Results from this cross-sectional study showed that the majority of participants experienced sexual self-discrepancies and that they experienced a significant inverse correlation between sexual self-discrepancies and sexual satisfaction. In multivariate models, sex frequency was the strongest predictor of sexual satisfaction. There were no correlations between sexual self-discrepancies and relationship satisfaction. Future measurement research should examine the role of sex frequency in the experience of sexual satisfaction. Education on maximizing pleasure and minimizing pain may aid women to cope with the negative impact of pain.

Entity theory of emotion was associated with more daily negative affect during quarantine: Evidence from a 14-day diary study among healthy young adults

During the COVID-19 pandemic, quarantine has been implemented as a physical distancing measure to reduce the risk of transmission. However, no studies have examined the relationship between quarantine and daily affective experiences. Few studies have examined the individual-level factors that may alleviate or strengthen the negative impact of quarantine on daily affective experiences. To this end, we conducted a diary study by comparing the affective experiences of people in quarantine with those of people not subject to quarantine. There were 201 participants in the study. After the pretest collecting responses on demographic information and entity theory of emotion, the participants completed a daily questionnaire measuring their daily positive and negative affect for 14 consecutive days. The results of hierarchical linear modeling showed that the participants in the quarantine condition reported less daily positive affect than those in the social interaction condition. We found that when the participants under quarantine believed more strongly that their emotions could not be changed, they reported a higher level of daily negative affect. These findings demonstrate the role of entity theory of emotion in understanding daily negative affect during quarantine.

Measuring 'self': preliminary validation of a short form of the Self Experiences Questionnaire in people with chronic pain

BACKGROUND

People with chronic pain often struggle with their sense of self and this can adversely impact their functioning and well-being. Acceptance and Commitment Therapy particularly includes a process related to this struggle with self. A measure for this process, the Self Experiences Questionnaire (SEQ), was previously developed in people with chronic pain.

PURPOSE

The aim of the current study was to validate a shorter version of the SEQ in people with chronic pain to reduce respondent burden and facilitate further research.

METHODS

Data from 477 participants attending an interdisciplinary pain management programme were included. Participants completed measures of treatment processes (self-as-context, pain acceptance, cognitive fusion and committed action) and outcomes (pain, pain interference, work and social adjustment and depression) at baseline and post-treatment. Confirmatory factor analysis was used for item reduction. Correlations between scores from the shorter SEQ and other process and outcome variables were calculated to examine validity. Change scores of the shorter SEQ and their correlations with changes in outcome variables were examined for responsiveness.

RESULTS

An eight-item SEQ (SEQ-8) scale including two factors, namely Self-as-Distinction and Self-as-Observer, emerged, demonstrating good reliability (Cronbach's α = .87-.90) and validity (|r| = .14-.52). Scores from SEQ-8 significantly improved after the treatment (d = .15-21), and these improvements correlated with improvements in most outcomes.

CONCLUSIONS

The SEQ-8 appears to be a reliable and valid measure of self. This shorter format may facilitate intensive longitudinal investigation into sense of self and functioning and well-being.

Borderline Personality Disorder Features and Risk for Prescription Opioid Misuse in a Chronic Pain Sample: Roles for Identity Disturbances and Impulsivity

Although borderline personality disorder (BPD) is associated with both chronic pain and substance abuse, little research examines how BPD features in chronic pain patients may constitute a risk factor for misuse of prescription opioids, and no prior research has examined which particular component(s) of BPD might put chronic pain patients at risk-an oversight that undermines prevention and treatment of such problematic opioid use. In a cross-sectional study of patients in treatment for chronic pain (N = 147), BPD features were associated with several measures of prescription opioid misuse, even controlling for pain severity and interference. Specifically, the identity disturbances and self-harmful impulsivity facets of BPD were most consistently associated with opioid misuse, and exploratory analyses suggested that these factors may be interactive in their effects. Together, these results suggest that BPD features-especially unstable identity and self-harmful impulsivity-play a unique role in problematic prescription opioid use in chronic pain settings.

Neural activations during self-related processing in patients with chronic pain and effects of a brief self-compassion training - A pilot study

Chronic pain negatively affects psychological functioning including self-perception. Self-compassion may improve self-related functioning in patients with chronic pain but understanding of the neural mechanisms is limited. In this study, twenty patients with chronic low back pain read negative self-related situations and were instructed to be either self-reassuring or self-critical while undergoing fMRI. Patients rated their feelings of self-reassurance and self-criticism during each condition, and brain responses were contrasted with neutral instructions. Trait self-compassion measures (SCS) were also acquired. Brain activations during self-criticism and self-reassurance were localized to prefrontal, self- and emotion-processing areas, such as medial prefrontal cortex, dorsolateral prefrontal cortex (dlPFC), dorsal anterior cingulate cortex and posterior cingulate cortex. Self-reassurance resulted in more widespread and stronger activations relative to self-criticism. Patients then completed a brief self-compassion training (8 contact hours, 2 weeks home practice). Exploratory pre-post comparisons in thirteen patients found that feelings of self-criticism were significantly reduced and brain activations were greater in the anterior insula and prefrontal cortical regions such as dlPFC. Pre-post increases in dlPFC activation correlated with increased self-compassion (SCS), suggesting that early self-compassion skills might primarily target self-criticism via dlPFC upregulation. Future controlled studies on self-compassion training in chronic pain populations should extend these results.

Acceptance and commitment therapy for chronic pain: protocol of a systematic review and individual participant data meta-analysis

BACKGROUND

Acceptance and commitment therapy (ACT) can be effective in treating chronic pain. Despite evidence supporting the effectiveness of ACT, uncertainties remain regarding which subgroups in the chronic pain population are likely to benefit most and least. This protocol describes the application for two meta-analytic approaches, one at the level of individual participant data and the other at the level of aggregated data, from randomized controlled trials of ACT for chronic pain (ACT-CP-MA).

METHODS

We will systematically conduct literature searches in CENTRAL, MEDLINE, EMBASE, PsycINFO, and trial registers. Two reviewers will independently select studies for inclusion and data extraction. ACT-CP-MA will include randomized controlled trials with ACT for chronic pain compared to control conditions for adults (≥ 18 years) with chronic pain (> 3 months). We will invite the authors of all eligible trials to share individual participant data. Outcomes will include standardized measures of pain interference, pain intensity, depression, anxiety, health-related quality of life, participants' rating of overall improvement, and ACT-related process variables. Using the Cochrane Collaboration's tool and GRADE, reviewers will independently check for risk of bias, quality of evidence, and strength of recommendations. In the individual participant data meta-analysis, we will use a one-step approach where participants are clustered with studies and data from all studies are modeled simultaneously. For analyses, we will use mixed-effects models. Additionally, we will employ a meta-analysis with aggregate data and compare the results of both meta-analyses.

DISCUSSION

This collaborative meta-analysis of individual participant data from randomized controlled trials of ACT for chronic pain versus control conditions will demonstrate how the known benefits of ACT for chronic pain vary across different subtypes of the chronic pain population. The results of the meta-analyses will be based on a comprehensive search of multiple databases and will help to inform future clinical trials and decision-making on the use of ACT in chronic pain and improve the quality, design, and reporting of future trials in this field.

Are We Speaking the Same Language? Finding Theoretical Coherence and Precision in "Mindfulness-Based Mechanisms" in Chronic Pain

Objective

Over the past 50 years, the field of chronic pain has witnessed an evolution of psychological approaches with some notable success. Some of this evolution has included "mindfulness-based interventions" (MBIs), now regarded as having encouraging partial support for their effectiveness. However, several theoretical challenges remain that may inhibit the progress of MBIs. These challenges include a lack of clarity surrounding the mindfulness construct itself, the proliferation of purported underlying mechanisms arising from different theories, and limited evidence for the mechanisms through which MBIs work. The current conceptual review provides a critique of existing theoretical models of mindfulness that have been applied to understanding and treating chronic pain.

Design

A conceptual narrative review was conducted.

Setting

Treatment programs for people with chronic pain.

Patients

Individuals with any type of chronic pain.

Interventions

MBIs for chronic pain.

Outcome Measures

Mindfulness-based mechanisms explored in relation to several domains of functioning.

Results and Conclusions

Based on this assessment, a summary of available evidence for a particular contextual behavioral theory of "mindfulness"-psychological flexibility-is outlined. Findings show the need for further integration of existing mindfulness constructs to better guide development and evaluation of mindfulness-based treatment methods in the future.

What Works and Does Not Work in a Self-Management Intervention for People With Chronic Pain? Qualitative Systematic Review and Meta-Synthesis

BACKGROUND

Self-management interventions fostering self-efficacy improve the well-being of people with chronic pain.

PURPOSE

The purpose of this study was to synthesize the enablers (what works) and barriers (what does not) of incorporating self-management strategies for people in everyday life after completion of a pain self-management intervention.

DATA SOURCES

Major electronic databases (MEDLINE, AMED, PsycINFO, Cochrane Library, PubMed, CINAHL, Scopus, and Google Scholar) were searched from inception to July 2016.

STUDY SELECTION

Study selection included qualitative and mixed-method studies that explored the perceptions of individuals with chronic pain after completion of a self-management intervention.

DATA EXTRACTION

A thematic analysis approach was used to synthesize the review findings, and a Confidence in the Evidence from Reviews of Qualitative Research (CERQual) Approach was used to assess the level of confidence.

DATA SYNTHESIS

Thirty-three studies with 512 participants were included. Enablers to self-management included self-discovery-the ability to distinguish self (ie, body, thoughts, and feelings) from pain; feeling empowered by incorporating self-management strategies into practice; and supportive ambience via collaborative relationships with clinicians and support from family and friends. Barriers to self-management included difficulty with sustaining motivation for pain self-management; distress experienced from ongoing pain, anxiety, and depression; and unsupportive relationships with clinicians, family, and friends.

LIMITATIONS

This review only included interventions that involved at least 4 self-management skills; thus, informative studies may have been missed. The follow-up period varied from immediately after the intervention to 72 months following the intervention; therefore, it is uncertain which of the key enablers and barriers were most influential long term. Only articles published in the English language were included; studies conducted in low- and middle-income countries could not be located.

CONCLUSIONS

The sustained effort to self-manage chronic pain could be exhausting, and motivation could wane over time following intervention. Providing intermittent support in the form of booster sessions and peer support groups may be important. Person-centered care via shared decision making and guided problem solving is essential to facilitating ongoing self-management.

Preliminary investigation of self-as-context in people with fibromyalgia

Acceptance and commitment therapy (ACT), based on the Psychological Flexibility (PF) model, has been recently applied to fibromyalgia (FM), and appeared effective in improving functioning. However, evidence for some of the processes within the PF model, self-as-context (SAC) in particular, is lacking within this population. The current study validates a measure of SAC, the Self Experiences Questionnaire (SEQ), and preliminarily investigates the role of SAC in relation to functioning in FM. Participants (N = 298, 93.3% women) self-reporting a diagnosis of FM were recruited via the Internet and completed an online survey. Measures included pain, pain acceptance and SAC, as processes, and pain interference, work and social adjustment, depression and depression-related interference, as outcomes. Confirmatory factor analysis of the SEQ suggested a bi-factor structure, with a general factor underlying all items and two sub-factors, self-as-distinction and self-as-observer (χ2 = 46.55, p = .06, comparative fit index (CFI) = .99, Tucker-Lewis Index (TLI) = .99, root mean square error of approximation (RMSEA) = .04). Component factors showed good reliability, Cronbach's α = .90, and construct validity, supported by significant Pearson's correlations between SEQ scores, acceptance and outcomes (r = -.14 to -.33). In multiple regression analyses, SEQ scores significantly predicted pain-related interference (β = -.17, p < .05), work and social adjustment (β = -.14, p < .05) and depression (β = -.21, p < .01), but not depression-related interference, after controlling for pain, but only significantly predicted depression after controlling pain acceptance. These preliminary results show potentially important associations between SAC and functioning in people with FM.
