The health effects of at-home written emotional disclosure in fibromyalgia: a randomized trial

Peer Support for Chronic Pain in Online Health Communities: Quantitative Study on the Dynamics of Social Interactions in a Chronic Pain Forum

BACKGROUND

Peer support for chronic pain is increasingly taking place on social media via social networking communities. Several theories on the development and maintenance of chronic pain highlight how rumination, catastrophizing, and negative social interactions can contribute to poor health outcomes. However, little is known regarding the role web-based health discussions play in the development of negative versus positive health attitudes relevant to chronic pain.

OBJECTIVE

This study aims to investigate how participation in online peer-to-peer support communities influenced pain expressions by examining how the sentiment of user language evolved in response to peer interactions.

METHODS

We collected the comment histories of 199 randomly sampled Reddit (Reddit, Inc) users who were active in a popular peer-to-peer chronic pain support community over 10 years. A total of 2 separate natural language processing methods were compared to calculate the sentiment of user comments on the forum (N=73,876). We then modeled the trajectories of users' language sentiment using mixed-effects growth curve modeling and measured the degree to which users affectively synchronized with their peers using bivariate wavelet analysis.

RESULTS

In comparison to a shuffled baseline, we found evidence that users entrained their language sentiment to match the language of community members they interacted with (t198=4.02; P<.001; Cohen d=0.40). This synchrony was most apparent in low-frequency sentiment changes unfolding over hundreds of interactions as opposed to reactionary changes occurring from comment to comment (F2,198=17.70; P<.001). We also observed a significant trend in sentiment across all users (β=-.02; P=.003), with users increasingly using more negative language as they continued to interact with the community. Notably, there was a significant interaction between affective synchrony and community tenure (β=.02; P=.02), such that greater affective synchrony was associated with negative sentiment trajectories among short-term users and positive sentiment trajectories among long-term users.

CONCLUSIONS

Our results are consistent with the social communication model of pain, which describes how social interactions can influence the expression of pain symptoms. The difference in long-term versus short-term affective synchrony observed between community members suggests a process of emotional coregulation and social learning. Participating in health discussions on Reddit appears to be associated with both negative and positive changes in sentiment depending on how individual users interacted with their peers. Thus, in addition to characterizing the sentiment dynamics existing within online chronic pain communities, our work provides insight into the potential benefits and drawbacks of relying on support communities organized on social media platforms.

Arts Therapy and Its Implications in Chronic Pain Management: A Narrative Review

Chronic nonmalignant pain is recognized as a complex, dynamic, phenomenological interplay between biological, psychological, and social factors that are individual to the person suffering from it. Therefore, its management and treatment ought to entail the individual's biopsychosocial aspects that are often addressed by collaborative, inter/multidisciplinary multimodal care, as there is no biologic treatment. In an effort to enhance inter/multidisciplinary multimodal care, a narrative review of arts therapy as a mind-body intervention and its efficacy in chronic pain populations has been conducted. Changes in emotional and physical symptoms, especially pain intensity, during arts therapy sessions have also been discussed in in the context of attention distraction strategy. Arts therapy (visual art, music, dance/movement therapy, etc.) have been investigated to summarize relevant findings and to highlight further potential benefits, limitations, and future directions in this area. We reviewed 16 studies of different design, and the majority reported beneficial effects of art therapy in patients' management of chronic pain and improvement in pain, mood, stress, and quality of life. However, the results are inconsistent and unclear. It was discovered that there is a limited amount of high-quality research available on the implications of arts therapy in chronic nonmalignant pain management. Due to the reported limitations, low effectiveness, and inconclusive findings of arts therapy in the studies conducted so far, further research with improved methodological standards is required.

The relationship of alexithymia to pain and other symptoms in fibromyalgia: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

People with fibromyalgia (FM) often report having difficulty with emotional identification and expression, and this "alexithymia" may contribute to their pain and other symptoms. Multiple studies have assessed alexithymia in FM, and we systematically reviewed and meta-analyzed this literature to: (a) describe the prevalence of alexithymia in people with FM; (b) compare the level of alexithymia in FM to both healthy controls and controls with other pain conditions; and (c) determine the association of alexithymia to pain intensity, depression, and anxiety in people with FM.

DATABASES AND DATA TREATMENT

Following PRISMA guidelines, we searched multiple databases (Scopus, PubMed/MEDLINE, Embase, Web of Science, PsycINFO and Google Scholar) from inception to May 31, 2022. Study quality was assessed with The Joanna Briggs Institute (JBI) tools for cross-sectional studies, and STATA:17 was used for meta-analysis. A total of 32 studies met eligibility criteria and were included in meta-analyses.

RESULTS

The prevalence of alexithymia in FM averaged 48%. People with FM had substantially higher alexithymia than healthy controls (SMD = 1.00; 95% CI: 0.79 to 1.22), as well people with other pain-related conditions (SMD = 0.35, 95% CI = 0.04 to 0.65), particularly rheumatoid arthritis (SMD = 0.49; 95% CI: 0.08-0.91). Alexithymia was positively associated with pain intensity (r = 0.24), anxiety (r = 0.50), and depression (r = 0.41) among people with FM.

CONCLUSIONS

Due to the high level of alexithymia in people with FM and the positive relationship of alexithymia with pain and psychological distress, interventions to improve emotional awareness, expression, and processing in FM are recommended.

Research on Expressive Writing in Psychology: A Forty-year Bibliometric Analysis and Visualization of Current Status and Research Trends

This study offers a systematic review of global academic publications of studies on expressive writing in psychology to date. By using two visualization tools VOSviewer and CiteSpace, we analyzed 1,429 articles on expressive writing from the Web of Science (WoS) Core Collection database. This study might be the first attempt at providing a visualized analysis of the existing expressive writing research. It discusses the results from the following three aspects: (1) the descriptive analysis of general results based on publications, (2) the content analysis based on highly cited articles and keyword analysis, (3) the thematic evolution based on co-word analysis and bursts detection. It is found that the application of expressive writing to minority ethnic groups might be one of the future research interests. The study proposes the necessity of conducting research in the context of positive psychology, argues for a combined use of creative and expressive writing in future studies, and suggests the potential of second/foreign language expressive writing research. The study can be used to enhance researchers’ understanding of expressive writing research and provide insights into future research opportunities in this area.

Efficacy of nonpharmacological interventions for individual features of fibromyalgia: a systematic review and meta-analysis of randomised controlled trials

ABSTRACT

Fibromyalgia is a highly heterogeneous condition, but the most common symptoms are widespread pain, fatigue, poor sleep, and low mood. Nonpharmacological interventions are recommended as first-line treatment of fibromyalgia. However which interventions are effective for the different symptoms is not well understood. The objective of this study was to assess the efficacy of nonpharmacological interventions on symptoms and disease-specific quality of life. Seven databases were searched from their inception until June 1, 2020. Randomised controlled trials comparing any nonpharmacological intervention to usual care, waiting list, or placebo in people with fibromyalgia aged >16 years were included without language restriction. Fibromyalgia Impact Questionnaire (FIQ) was the primary outcome measure. Standardised mean difference and 95% confidence interval were calculated using random effects model. The risk of bias was evaluated using the modified Cochrane tool. Of the 16,251 studies identified, 167 randomised controlled trials (n = 11,012) assessing 22 nonpharmacological interventions were included. Exercise, psychological treatments, multidisciplinary modality, balneotherapy, and massage improved FIQ. Subgroup analysis of different exercise interventions found that all forms of exercise improved pain (effect size [ES] -0.72 to -0.96) and depression (ES -0.35 to -1.22) except for flexibility exercise. Mind-body and strengthening exercises improved fatigue (ES -0.77 to -1.00), whereas aerobic and strengthening exercises improved sleep (ES -0.74 to -1.33). Psychological treatments including cognitive behavioural therapy and mindfulness improved FIQ, pain, sleep, and depression (ES -0.35 to -0.55) but not fatigue. The findings of this study suggest that nonpharmacological interventions for fibromyalgia should be individualised according to the predominant symptom.

The Link between Fibromyalgia Syndrome and Anger: A Systematic Review Revealing Research Gaps

Anger has been associated with increased pain perception, but its specific connection with Fibromyalgia Syndrome (FMS) has not yet been established in an integrated approach. Therefore, the present systematic review focuses on exploring this connection, and based on this connection, delimiting possible gaps in the research, altogether aimed at improving FMS clinical intervention and guiding future research lines. Anger is considered a basic negative emotion that can be divided into two dimensions: anger-in (the tendency to repress anger when it is experienced) and anger-out (the leaning to express anger through verbal or physical means). The current systematic review was performed based on the guidelines of the PRISMA and Cochrane Collaborations. The Prospective Register of Systematic Reviews (PROSPERO) international database was forehand used to register the review protocol. The quality of chosen articles was assessed and the main limitations and research gaps resulting from each scientific article were discussed. The search included PubMed, Scopus, and Web of Science databases. The literature search identified 13 studies eligible for the systematic review. Levels of anger-in have been shown to be higher in FMS patients compared to healthy participants, as well as patients suffering from other pain conditions (e.g., rheumatoid arthritis). FMS patients had also showed higher levels of state and trait anxiety, worry and angry rumination than other chronic pain patients. Anger seems to amplify pain especially in women regardless FMS condition but with a particularly greater health-related quality of life´s impact in FMS patients. In spite of the relevance of emotions in the treatment of chronic pain, including FMS, only two studies have proposed intervention programs focus on anger treatment. These two studies have observed a positive reduction in anger levels through mindfulness and a strength training program. In conclusion, anger might be a meaningful therapeutic target in the attenuation of pain sensitivity, and the improvement of the general treatment effects and health-related quality of life in FMS patients. More intervention programs directed to reduce anger and contribute to improve well-being in FMS patients are needed.

Written Emotional Disclosure Can Promote Athletes' Mental Health and Performance Readiness During the COVID-19 Pandemic

The widespread effects of the coronavirus disease 2019 (COVID-19) pandemic have negatively impacted upon many athletes’ mental health and increased reports of depression as well as symptoms of anxiety. Disruptions to training and competition schedules can induce athletes’ emotional distress, while concomitant government-imposed restrictions (e.g., social isolation, quarantines) reduce the availability of athletes’ social and emotional support. Written Emotional Disclosure (WED) has been used extensively in a variety of settings with diverse populations as a means to promote emotional processing. The expressive writing protocol has been used to a limited extent in the context of sport and predominantly in support of athletes’ emotional processing during injury rehabilitation. We propose that WED offers an evidence-based treatment that can promote athletes’ mental health and support their return to competition. Research exploring the efficacy of the expressive writing protocol highlights a number of theoretical models underpinning the positive effects of WED; we outline how each of these potential mechanisms can address the multidimensional complexity of the challenging circumstances arising from the COVID-19 pandemic (e.g., loss of earnings, returning to training and competition). Considerations and strategies for using WED to support athletes during the COVID-19 pandemic are presented.

The Effects of a Life Stress Emotional Awareness and Expression Interview for Women with Chronic Urogenital Pain: A Randomized Controlled Trial

OBJECTIVE

Women with chronic urogenital pain (CUP) conditions have elevated rates of lifetime trauma, relational stress, and emotional conflicts, but directly assessing and treating psychological stress is rarely done in women's health care settings. We developed and tested the effects on patients' somatic and psychological symptoms of a life stress interview that encourages disclosure about stressors and uses experiential techniques to increase awareness of links between stress, emotions, and symptoms.

METHODS

In this randomized trial, women with CUP recruited at a multidisciplinary women's urology center received either a single 90-minute life stress interview (N = 37) or no interview (treatment-as-usual control; N = 25). Self-report measures of pain severity (primary outcome), pain interference, pelvic floor symptoms, and psychological symptoms (anxiety and depression) were completed at baseline and six-week follow-up.

RESULTS

Differences between the life stress interview and control conditions at follow-up were tested with analyses of covariance, controlling for baseline level of the outcome and baseline depression. Compared with the control condition, the interview resulted in significantly lower pain severity and pelvic floor symptoms, but the interview had no effect on pain interference or psychological symptoms.

CONCLUSIONS

An intensive life stress emotional awareness expression interview improved physical but not psychological symptoms among women with CUP seen in a tertiary care clinic. This study suggests that targeting stress and avoided emotions and linking them to symptoms may be beneficial for this complex group of patients.

Psychological Therapy for Centralized Pain: An Integrative Assessment and Treatment Model

OBJECTIVE

Chronic pain is a significant health problem that is increasing in prevalence, and advances in treatment are needed.

METHODS

We briefly review the leading evidence-based psychological therapies for chronic pain-cognitive-behavioral and acceptance/mindfulness-based therapies-and examine several limitations and missing perspectives of these approaches. We review six lesser-known interventions that address these limitations, and we describe our integrative model for psychological assessment and treatment of centralized pain. We present a typical patient and describe how we apply this approach, along with challenges to its implementation and possible solutions to these challenges.

RESULTS

Greater pain treatment efficacy may be possible if clinicians: (a) distinguish patients with primarily centralized (i.e., somatoform or nociplastic) pain from those with primarily peripheral (nociceptive, inflammatory, or neuropathic) pain; (b) acknowledge the capacity of the brain not only to modulate pain but also generate as well as attenuate or eliminate centralized pain; (c) consider the powerful role that adverse life experiences and psychological conflicts play in centralized pain; and (d) integrate emotional processing and interpersonal changes into treatment. Our integrative treatment involves delivering a progression of interventions, as needed, to achieve pain reduction: tailored pain neuroscience education, cognitive and mindfulness skills to decrease the pain danger alarm mechanism, behavioral engagement in avoided painful and other feared activities, emotional awareness and expression to reverse emotional avoidance and overcome trauma or psychological conflict, and adaptive communication to decrease interpersonal stress.

CONCLUSIONS

This integrative assessment and treatment model has the potential to substantially reduce and sometimes eliminate centralized pain by changing the cognitive, behavioral, emotional, and interpersonal processes that trigger and maintain centralized pain.

Can linguistic analysis be used to identify whether adolescents with a chronic illness are depressed?

Comorbid depression is common in adolescents with chronic illness. We aimed to design and test a linguistic coding scheme for identifying depression in adolescents with chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME), by exploring features of e-consultations within online cognitive behavioural therapy treatment. E-consultations of 16 adolescents (aged 11-17) receiving FITNET-NHS (Fatigue in teenagers on the interNET in the National Health Service) treatment in a national randomized controlled trial were examined. A theoretically driven linguistic coding scheme was developed and used to categorize comorbid depression in e-consultations using computerized content analysis. Linguistic coding scheme categorization was subsequently compared with classification of depression using the Revised Children's Anxiety and Depression Scale published cut-offs (t-scores ≥65, ≥70). Extra linguistic elements identified deductively and inductively were compared with self-reported depressive symptoms after unblinding. The linguistic coding scheme categorized three (19%) of our sample consistently with self-report assessment. Of all 12 identified linguistic features, differences in language use by categorization of self-report assessment were found for "past focus" words (mean rank frequencies: 1.50 for no depression, 5.50 for possible depression, and 10.70 for probable depression; p < .05) and "discrepancy" words (mean rank frequencies: 16.00 for no depression, 11.20 for possible depression, and 6.40 for probable depression; p < .05). The linguistic coding profile developed as a potential tool to support clinicians in identifying comorbid depression in e-consultations showed poor value in this sample of adolescents with CFS/ME. Some promising linguistic features were identified, warranting further research with larger samples.

The Physical and the Emotional: Case Report, Mixed-Methods Development, and Discussion

There is a growing recognition that emotional problems are important to physical health outcomes. In response, primary care clinics have introduced self-report checklists to identify patients with emotional disorders such as depression or anxiety. Yet psychodynamic theory posits that certain emotional problems may be unconscious and unspoken, and thus not discernible on self-report checklists, and studies show that checklists do not identify every patient who needs treatment. New clinical tools are needed to identify subtle and complex presentations. We aimed to develop an innovative mixed-methods approach characterizing different types of verbal expression of feelings, drawing on psychodynamic theory and empirical research. We outline the development of the mixed-methods approach, including our theoretical framework and use of semi-structured interview data from Partners in Care (PIC), a randomized controlled trial of quality improvement for depression. We then illustrate the approach with one case: an older female PIC participant who screened positive for depression on all study self-reports. The approach delineates three qualitatively different categories of words-specific feeling words, vague feeling words, and physical words-that were quantified to define a measurable pattern for our participant. Clinicians could be trained to identify these categories of words in the context of a discussion of feelings to better detect and understand subtle emotional problems in patients who have difficulty talking openly about their feelings. Next steps include furthering face and construct validity and test-retest reliability, examining the prevalence of these patterns in a larger sample, and assessing correlates of patterns.

Investigating the role of beliefs about emotions, emotional suppression and distress within a pain management programme for fibromyalgia

Introduction

This study aims to explore the relationships between beliefs about emotions, emotional suppression, distress and global impact (i.e. the extent to which a patient's symptoms impact their life) in a longitudinal design with patients who are taking part in a pain management programme.

Methods

A total of 40 participants with fibromyalgia took part in pain management programmes at multiple sites as part of their usual care in the National Health Service. Measures of beliefs about the unacceptability of experiencing and expressing emotions, emotional suppression, distress and global impact were completed before and after the programmes.

Results

Beliefs about emotions significantly reduced following treatment, but emotional suppression did not. Changes in beliefs about emotion correlated with changes in emotional suppression. Changes in distress were related to changes in suppression and the relationship between global impact and beliefs about emotions was approaching significance.

Conclusion

Emotional suppression and beliefs about emotions may play a role in the improvement in distress following treatment. However, future research should examine these variables as mediators of the effect of treatment compared to waitlist controls in a larger sample.

Changing Beliefs About Emotions in IBS: A Single Case Design

BACKGROUND

Previous research suggests benefits of targeting beliefs about the unacceptability of emotions in treatment for irritable bowel syndrome (IBS).

AIMS

The current study developed and tested an intervention focusing on beliefs and behaviours around emotional expression.

METHOD

Four participants with IBS attended five group sessions using cognitive behavioural techniques focusing on beliefs about the unacceptability of expressing emotions. Bi-weekly questionnaires were completed and a group interview was conducted. This study used an AB design with four participants.

RESULTS

Averages indicate that participants showed decreases in beliefs about unacceptability of emotions and emotional suppression during the intervention, although this was not reflected in any of the individual trends in Beliefs about Emotions Scale scores and was significant in only one individual case for Courtauld Emotional Control Scale scores. Affective distress and quality of life improved during follow-up, with only one participant not improving with regard to distress. Qualitative data suggest that participants felt that the intervention was beneficial, referencing the value in sharing their emotions.

CONCLUSIONS

This study suggests the potential for beliefs about emotions and emotional suppression to be addressed in cognitive behavioural interventions in IBS. That beliefs and behaviours improved before outcomes suggests they may be important processes to investigate in treatment for IBS.

Emotional awareness and expression therapy, cognitive behavioral therapy, and education for fibromyalgia: a cluster-randomized controlled trial

Patients with fibromyalgia (FM) experience increased lifetime levels of psychosocial adversity, trauma, and emotional conflict. To address these risk factors, we developed emotion awareness and expression therapy (EAET) and tested its benefits against an active control condition, FM education, and the field's gold standard intervention for FM, cognitive behavioral therapy (CBT) for symptom management. Adults with FM (N = 230) formed 40 treatment groups, which were randomized to EAET, CBT, or education and given 8, 90-minute sessions. Patient-reported outcomes were assessed at baseline, posttreatment, and 6-month follow-up (primary end point). Retention of patients to follow-up was excellent (90.4%). Intent-to-treat analyses indicated that although EAET did not differ from FM education on pain severity (primary outcome), EAET had significantly better outcomes than FM education on overall symptoms, widespread pain, physical functioning, cognitive dysfunction, anxiety, depression, positive affect, and life satisfaction (between-condition d's ranging from 0.29-0.45 SD) and the percentage of patients reporting being "very much/much" improved (34.8% vs 15.4%). Emotional awareness and expression therapy did not differ from CBT on the primary or most secondary outcomes, but compared to CBT, EAET led to significantly lower FM symptoms (d = 0.35) and widespread pain (d = 0.37) and a higher percentage of patients achieving 50% pain reduction (22.5% vs 8.3%). In summary, an intervention targeting emotional awareness and expression related to psychosocial adversity and conflict was well received, more effective than a basic educational intervention, and had some advantages over CBT on pain. We conclude that EAET should be considered as an additional treatment option for FM.

Hypnosis is More Effective than Clinical Interviews

To determine whether hypnosis is more effective than conventional interviewing to find traumatic life events in patients with fibromyalgia, we carried out a within-subject experimental design with complete intragroup counterbalancing. Thirty-two women under care in a public primary care center gave 2 identical interviews, with an interval of 3 months, in which the occurrence of traumatic life events was explored, once in a state of wakefulness and once in a state of hypnosis. The state of consciousness was evaluated using 3 measures: bispectral index, skin conductance level, and pain intensity. In the hypnotic state, the patients expressed 9.8 times more traumatic life events than in the waking state, a statistically significant difference with a large effect size.

Determining the impact of a new physiotherapist-led primary care model for back pain: protocol for a pilot cluster randomized controlled trial

BACKGROUND

Back pain is a leading contributor to disability, healthcare costs, and lost work. Family physicians are the most common first point of contact in the healthcare system for people with back pain, but physiotherapists (PTs) may be able to support the primary care team through evidence-based primary care. A cluster randomized trial is needed to determine the clinical, health system, and societal impact of a primary care model that integrates physiotherapists at the first visit for people with back pain. Prior to conducting a future fully powered cluster randomized trial, we need to demonstrate feasibility of the methods. Therefore, the purpose of this pilot study will be to: 1) Determine feasibility of patient recruitment, assessment procedures, and retention. 2) Determine the feasibility of training and implementation of a new PT-led primary care model for low back pain (LBP) 3) Explore the perspectives of patients and healthcare providers (HCPs) related to their experiences and attitudes towards the new service delivery model, barriers/facilitators to implementation, perceived satisfaction, perceived value, and impact on clinic processes and patient outcomes.

METHODS

This pilot cluster randomized controlled trial will enroll four sites and randomize them to implement a new PT-led primary care model for back pain or a usual physician-led primary care model. All adults booking a primary care visit for back pain will be invited to participate. Feasibility outcomes will include: recruitment and retention rates, completeness of assessment data, PT training participation and confidence after training, and PT treatment fidelity. Secondary outcomes will include the clinical, health system, cost, and process outcomes planned for the future fully powered cluster trial. Results will be analyzed and reported descriptively and qualitatively. To explore perspectives of both HCPs and patients, we will conduct semi-structured qualitative interviews with patients and focus groups with HCPs from participants in the PT-led primary care sites.

DISCUSSION

If this pilot demonstrates feasibility, a fully powered trial will provide evidence that has the potential to transform primary care for back pain. The full trial will inform future service design, whether these models should be more widely implemented, and training agendas.

Effectiveness of Occupational Therapy Interventions for Adults With Fibromyalgia: A Systematic Review

OBJECTIVE

This systematic review addresses the effectiveness of occupational therapy-related interventions for adults with fibromyalgia.

METHOD

We examined the literature published between January 2000 and June 2014. A total of 322 abstracts from five databases were reviewed. Forty-two Level I studies met the inclusion criteria. Studies were evaluated primarily with regard to the following outcomes: daily activities, pain, depressive symptoms, fatigue, and sleep.

RESULTS

Strong evidence was found for interventions categorized for this review as cognitive-behavioral interventions; relaxation and stress management; emotional disclosure; physical activity; and multidisciplinary interventions for improving daily living, pain, depressive symptoms, and fatigue. There was limited to no evidence for self-management, and few interventions resulted in better sleep.

CONCLUSION

Although the evidence supports interventions within the scope of occupational therapy practice for people with fibromyalgia, few interventions were occupation based.

'Isn't it ironic?' Beliefs about the unacceptability of emotions and emotional suppression relate to worse outcomes in fibromyalgia

Beliefs about the unacceptability of experiencing and expressing emotions have been found to be related to worse outcomes in people with persistent physical symptoms. The current study tested mediation models regarding emotional suppression, beliefs about emotions, support-seeking and global impact in fibromyalgia. One hundred eighty-two participants took part in an online questionnaire testing potential mechanisms of this relationship using mediation analysis. The model tested emotional suppression and affective distress as serial mediators of the relationship between beliefs about emotions and global impact. In parallel paths, two forms of support-seeking were tested (personal/emotional and symptom-related support-seeking) as mediators. Emotional suppression and affective distress significantly serially mediated the relationship between beliefs about emotions and global impact. Neither support-seeking variable significantly mediated this relationship. Results indicate a potential mechanism through which beliefs about emotions and global impact might relate which might provide a theoretical basis for future research on treatments for fibromyalgia.

Does therapeutic writing help people with long-term conditions? Systematic review, realist synthesis and economic considerations

BACKGROUND

Writing therapy to improve physical or mental health can take many forms. The most researched model of therapeutic writing (TW) is unfacilitated, individual expressive writing (written emotional disclosure). Facilitated writing activities are less widely researched.

DATA SOURCES

Databases, including MEDLINE, EMBASE, PsycINFO, Linguistics and Language Behaviour Abstracts, Allied and Complementary Medicine Database and Cumulative Index to Nursing and Allied Health Literature, were searched from inception to March 2013 (updated January 2015).

REVIEW METHODS

Four TW practitioners provided expert advice. Study procedures were conducted by one reviewer and checked by a second. Randomised controlled trials (RCTs) and non-randomised comparative studies were included. Quality was appraised using the Cochrane risk-of-bias tool. Unfacilitated and facilitated TW studies were analysed separately under International Classification of Diseases, Tenth Revision chapter headings. Meta-analyses were performed where possible using RevMan version 5.2.6 (RevMan 2012, The Cochrane Collaboration, The Nordic Cochrane Centre, Copenhagen, Denmark). Costs were estimated from a UK NHS perspective and three cost-consequence case studies were prepared. Realist synthesis followed Realist and Meta-narrative Evidence Synthesis: Evolving Standards guidelines.

OBJECTIVES

To review the clinical effectiveness and cost-effectiveness of TW for people with long-term conditions (LTCs) compared with no writing, or other controls, reporting any relevant clinical outcomes. To conduct a realist synthesis to understand how TW might work, and for whom.

RESULTS

From 14,658 unique citations, 284 full-text papers were reviewed and 64 studies (59 RCTs) were included in the final effectiveness reviews. Five studies examined facilitated TW; these were extremely heterogeneous with unclear or high risk of bias but suggested that facilitated TW interventions may be beneficial in individual LTCs. Unfacilitated expressive writing was examined in 59 studies of variable or unreported quality. Overall, there was very little or no evidence of any benefit reported in the following conditions (number of studies): human immunodeficiency virus (six); breast cancer (eight); gynaecological and genitourinary cancers (five); mental health (five); asthma (four); psoriasis (three); and chronic pain (four). In inflammatory arthropathies (six) there was a reduction in disease severity [n = 191, standardised mean difference (SMD) -0.61, 95% confidence interval (CI) -0.96 to -0.26] in the short term on meta-analysis of four studies. For all other LTCs there were either no data, or sparse data with no or inconsistent, evidence of benefit. Meta-analyses conducted across all of the LTCs provided no evidence that unfacilitated emotional writing had any effect on depression at short- (n = 1563, SMD -0.06, 95% CI -0.29 to 0.17, substantial heterogeneity) or long-term (n = 778, SMD -0.04 95% CI -0.18 to 0.10, little heterogeneity) follow-up, or on anxiety, physiological or biomarker-based outcomes. One study reported costs, no studies reported cost-effectiveness and 12 studies reported resource use; and meta-analysis suggested reduced medication use but no impact on health centre visits. Estimated costs of intervention were low, but there was insufficient evidence to judge cost-effectiveness. Realist synthesis findings suggested that facilitated TW is a complex intervention and group interaction contributes to the perception of benefit. It was unclear from the available data who might benefit most from facilitated TW.

LIMITATION

Difficulties with developing realist synthesis programme theory meant that mechanisms operating during TW remain obscure.

CONCLUSIONS

Overall, there is little evidence to support the therapeutic effectiveness or cost-effectiveness of unfacilitated expressive writing interventions in people with LTCs. Further research focused on facilitated TW in people with LTCs could be informative.

Prevalence and relevance of Type D personality in fibromyalgia

OBJECTIVE

Distressed (Type D) personality, combining high negative affectivity and social inhibition, is linked to poor health in various populations. Because patients with fibromyalgia experience high negative affect and show signs of social inhibition, this study aimed to examine the prevalence of Type D's components and their associations with health in an additive (worse health with both components present) or synergistic way (components amplifying each other's effects).

METHOD

Type D personality and physical and mental health were assessed online by 558 patients with self-reported fibromyalgia (94% women, age 47 ± 11 (21-77)years) by the Type D Scale-14 and RAND-36 Health Status Inventory.

RESULTS

Using the standard cutscores, Type D personality was present in 56.5% of patients. Negative affectivity alone and combined with social inhibition was associated with worse mental and, more limited, physical health, but no interactive (synergistic) associations were found.

CONCLUSIONS

Type D personality in fibromyalgia exceeds prevalence estimates in general, cardiovascular and chronic pain populations. Some indication of an additive but not of a synergistic effect was found, particularly for mental health, with clearly the largest associations for negative affectivity. The high prevalence of Type D's components may have specific treatment implications.

Mind and body therapy for fibromyalgia

BACKGROUND

Mind-body interventions are based on the holistic principle that mind, body and behaviour are all interconnected. Mind-body interventions incorporate strategies that are thought to improve psychological and physical well-being, aim to allow patients to take an active role in their treatment, and promote people's ability to cope. Mind-body interventions are widely used by people with fibromyalgia to help manage their symptoms and improve well-being. Examples of mind-body therapies include psychological therapies, biofeedback, mindfulness, movement therapies and relaxation strategies.

OBJECTIVES

To review the benefits and harms of mind-body therapies in comparison to standard care and attention placebo control groups for adults with fibromyalgia, post-intervention and at three and six month follow-up.

SEARCH METHODS

Electronic searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), EMBASE (Ovid), PsycINFO (Ovid), AMED (EBSCO) and CINAHL (Ovid) were conducted up to 30 October 2013. Searches of reference lists were conducted and authors in the field were contacted to identify additional relevant articles.

SELECTION CRITERIA

All relevant randomised controlled trials (RCTs) of mind-body interventions for adults with fibromyalgia were included.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies, extracted the data and assessed trials for low, unclear or high risk of bias. Any discrepancy was resolved through discussion and consensus. Continuous outcomes were analysed using mean difference (MD) where the same outcome measure and scoring method was used and standardised mean difference (SMD) where different outcome measures were used. For binary data standard estimation of the risk ratio (RR) and its 95% confidence interval (CI) was used.

MAIN RESULTS

Seventy-four papers describing 61 trials were identified, with 4234 predominantly female participants. The nature of fibromyalgia varied from mild to severe across the study populations. Twenty-six studies were classified as having a low risk of bias for all domains assessed. The findings of mind-body therapies compared with usual care were prioritised.There is low quality evidence that in comparison to usual care controls psychological therapies have favourable effects on physical functioning (SMD -0.4, 95% CI -0.6 to -0.3, -7.5% absolute change, 2 point shift on a 0 to 100 scale), pain (SMD -0.3, 95% CI -0.5 to -0.2, -3.5% absolute change, 2 point shift on a 0 to 100 scale) and mood (SMD -0.5, 95% CI -0.6 to -0.3, -4.8% absolute change, 3 point shift on a 20 to 80 scale). There is very low quality evidence of more withdrawals in the psychological therapy group in comparison to usual care controls (RR 1.38, 95% CI 1.12 to 1.69, 6% absolute risk difference). There is lack of evidence of a difference between the number of adverse events in the psychological therapy and control groups (RR 0.38, 95% CI 0.06 to 2.50, 4% absolute risk difference).There was very low quality evidence that biofeedback in comparison to usual care controls had an effect on physical functioning (SMD -0.1, 95% CI -0.4 to 0.3, -1.2% absolute change, 1 point shift on a 0 to 100 scale), pain (SMD -2.6, 95% CI -91.3 to 86.1, -2.6% absolute change) and mood (SMD 0.1, 95% CI -0.3 to 0.5, 1.9% absolute change, less than 1 point shift on a 0 to 90 scale) post-intervention. In view of the quality of evidence we cannot be certain that biofeedback has a little or no effect on these outcomes. There was very low quality evidence that biofeedback led to more withdrawals from the study (RR 4.08, 95% CI 1.43 to 11.62, 20% absolute risk difference). No adverse events were reported.There was no advantage observed for mindfulness in comparison to usual care for physical functioning (SMD -0.3, 95% CI -0.6 to 0.1, -4.8% absolute change, 4 point shift on a scale 0 to 100), pain (SMD -0.1, CI -0.4 to 0.3, -1.3% absolute change, less than 1 point shift on a 0 to 10 scale), mood (SMD -0.2, 95% CI -0.5 to 0.0, -3.7% absolute change, 2 point shift on a 20 to 80 scale) or withdrawals (RR 1.07, 95% CI 0.67 to 1.72, 2% absolute risk difference) between the two groups post-intervention. However, the quality of the evidence was very low for pain and moderate for mood and number of withdrawals. No studies reported any adverse events.Very low quality evidence revealed that movement therapies in comparison to usual care controls improved pain (MD -2.3, CI -4.2 to -0.4, -23% absolute change) and mood (MD -9.8, 95% CI -18.5 to -1.2, -16.4% absolute change) post-intervention. There was no advantage for physical functioning (SMD -0.2, 95% CI -0.5 to 0.2, -3.4% absolute change, 2 point shift on a 0 to 100 scale), participant withdrawals (RR 1.95, 95% CI 1.13 to 3.38, 11% absolute difference) or adverse events (RR 4.62, 95% CI 0.23 to 93.92, 4% absolute risk difference) between the two groups, however rare adverse events may include worsening of pain.Low quality evidence revealed that relaxation based therapies in comparison to usual care controls showed an advantage for physical functioning (MD -8.3, 95% CI -10.1 to -6.5, -10.4% absolute change) and pain (SMD -1.0, 95% CI -1.6 to -0.5, -3.5% absolute change, 2 point shift on a 0 to 78 scale) but not for mood (SMD -4.4, CI -14.5 to 5.6, -7.4% absolute change) post-intervention. There was no difference between the groups for number of withdrawals (RR 4.40, 95% CI 0.59 to 33.07, 31% absolute risk difference) and no adverse events were reported.

AUTHORS' CONCLUSIONS

Psychological interventions therapies may be effective in improving physical functioning, pain and low mood for adults with fibromyalgia in comparison to usual care controls but the quality of the evidence is low. Further research on the outcomes of therapies is needed to determine if positive effects identified post-intervention are sustained. The effectiveness of biofeedback, mindfulness, movement therapies and relaxation based therapies remains unclear as the quality of the evidence was very low or low. The small number of trials and inconsistency in the use of outcome measures across the trials restricted the analysis.

Holding back moderates the association between health symptoms and social well-being in patients undergoing hematopoietic stem cell transplantation

CONTEXT

Holding back, or withholding discussion of disease-related thoughts and emotions, is associated with negative outcomes including lower quality of life, diminished well-being, and relational distress. For patients undergoing hematopoietic stem cell transplantation (HSCT), the degree to which one holds back from discussing illness-related concerns may be an important determinant of social well-being and health; however, this has not been systematically assessed in this population.

OBJECTIVES

The purpose of the present study was to assess the moderating effects of holding back discussion of disease-related concerns on the relationship between health-related symptoms and social well-being in adult patients undergoing HSCT.

METHODS

Seventy autologous (n = 55) and allogeneic (n = 15) HSCT patients completed measures of holding back, social well-being, and health symptoms (i.e., pain, fatigue, sleep problems, cognitive problems) both before and after transplantation (i.e., three months after transplantation and six months after transplantation).

RESULTS

In patients with average to high levels of holding back, health symptoms were significantly related to lower levels of social well-being; however, for patients with low levels of holding back, the relationship between health symptoms and social well-being was not significant.

CONCLUSION

The results of the present study suggest that the level of holding back may be important in understanding how health-related symptoms relate to social well-being in patients undergoing HSCT. These findings underscore the importance of addressing how patients undergoing HSCT communicate about their disease with others as this may be related to their adjustment to illness and treatment.

Effect of written emotional disclosure on secondary hyperalgesia in women with trauma history

OBJECTIVE

This study investigated the effects of written emotional disclosure on a model of chronic pain in healthy women with and without trauma history.

METHOD

Participants were prescreened for their trauma history (N = 78) and randomized to a disclosure or a control writing condition. Pain testing occurred either 1 day or 1 month after disclosure. Capsaicin was applied to the forearm to evoke spontaneous burning pain at the application site and mechanical secondary hyperalgesia in the surrounding untreated skin.

RESULTS

As hypothesized, the effect of disclosure on the area and intensity of secondary hyperalgesia depended on trauma history and time of testing (F(1,69) ≥ 7.37, p = .008). Disclosure increased secondary hyperalgesia in participants with trauma history compared with those without trauma when testing occurred 1 day after writing (F(1,69) ≥ 5.27, p ≤ .025), whereas the opposite pattern was observed 1 month later (F(1,69) ≥ 4.88, p ≤ .031). Of the participants with trauma history in the disclosure condition, secondary hyperalgesia was reduced at 1 month compared with 1 day after writing (p = .001). Moreover, greater use of positive emotional words predicted reduced secondary hyperalgesia at 1 month (β = -0.71, p = .022). In contrast, disclosure had no effect on spontaneous pain.

CONCLUSIONS

Disclosure modulates secondary hyperalgesia observed in women with trauma history, producing a short-term enhancement and a long-term reduction. This suggests that disclosure has a long-term protective effect that reduces sensitization of pain, which may explain the therapeutic effects of disclosure in patients with chronic pain.

Emotional disclosure interventions for chronic pain: from the laboratory to the clinic

Life stress and the avoidance of negative emotions may contribute to chronic pain. The technique of written or spoken emotional disclosure can reverse emotional avoidance and improve health, and 18 randomized studies have tested it among people with chronic pain. We review these studies to provide guidance for the clinical use of this technique. The benefits of emotional disclosure for chronic pain are quite modest overall. Studies in rheumatoid arthritis show very limited effects, but two studies in fibromyalgia suggest that disclosure may be beneficial. Effects in other populations (headaches, cancer pain, pelvic pain, abdominal pain) are mixed. Moderator findings suggest that some patients are more likely to benefit than others. Emotional disclosure has been tested in well-controlled efficacy trials, leaving many unanswered questions related to translating this technique to practice. Issues needing further study include determining disclosure's effects outside of randomized controlled trials, identifying the optimal pain populations and specific individuals to target for disclosure, presenting a valid rationale for disclosure, selecting the location and method of disclosure, and choosing between cognitive-behavioral or emotional disclosure techniques.

Psychosocial interventions for managing pain in older adults: outcomes and clinical implications

Interest in the use of psychosocial interventions to help older adults manage pain is growing. In this article, we review this approach. The first section reviews the conceptual background for psychosocial interventions with a special emphasis on the biopsychosocial model of pain. The second section highlights three psychosocial interventions used with older adults: cognitive behavioural therapy, emotional disclosure, and mind-body interventions (specifically mindfulness-based stress reduction and yoga). The final section of the paper highlights important future directions for work in this area.

[Psychotherapy for patients with fibromyalgia syndrome. Systematic review, meta-analysis and guideline]

BACKGROUND

The scheduled update to the German S3 guidelines on fibromyalgia syndrome (FMS) by the Association of the Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften", AWMF; registration number 041/004) was planned starting in March 2011.

MATERIALS AND METHODS

The development of the guidelines was coordinated by the German Interdisciplinary Association for Pain Therapy ("Deutsche Interdisziplinären Vereinigung für Schmerztherapie", DIVS), 9 scientific medical societies and 2 patient self-help organizations. Eight working groups with a total of 50 members were evenly balanced in terms of gender, medical field, potential conflicts of interest and hierarchical position in the medical and scientific fields. Literature searches were performed using the Medline, PsycInfo, Scopus and Cochrane Library databases (until December 2010). The grading of the strength of the evidence followed the scheme of the Oxford Centre for Evidence-Based Medicine. The recommendations were based on level of evidence, efficacy (meta-analysis of the outcomes pain, sleep, fatigue and health-related quality of life), acceptability (total dropout rate), risks (adverse events) and applicability of treatment modalities in the German health care system. The formulation and grading of recommendations was accomplished using a multi-step, formal consensus process. The guidelines were reviewed by the boards of the participating scientific medical societies.

RESULTS AND CONCLUSION

Cognitive behavioral therapy combined with aerobic exercise (multicomponent therapy) is strongly recommended. Relaxation as single therapy should not be applied. The English full-text version of this article is available at SpringerLink (under "Supplemental").

Expressive disclosure to improve well-being in patients with amyotrophic lateral sclerosis: a randomised, controlled trial

Amyotrophic lateral sclerosis (ALS) is a terminal neurological disease associated with progressive paralysis, loss of communicative ability and functional decline. Expressive disclosure may help people with ALS, particularly those who are emotionally or socially inhibited, meet psychological challenges associated with the disease. People with ALS (N = 48) were randomised to expressive disclosure about their disease or no disclosure. Psychological well-being (affect, depression and quality of life) was assessed pre-intervention and also three and six months later. Results of multi-level models indicated that the group that disclosed thoughts and feelings about ALS had higher well-being than the control group at three months post-intervention, but not six months. Ambivalence over emotional expression (AEE) moderated three-month post-intervention well-being. Those low in AEE had higher well-being than those high in AEE regardless of condition. Those high in AEE, who disclosed, had increased well-being from pre-intervention, whereas controls had decreased well-being from pre-intervention. Expressive disclosure may be helpful for people with ALS, but only those who have difficulty expressing emotions. In addition, the intervention had only temporary effects; the dynamic challenges of ALS progression may mean that the effect of processing thoughts and feelings about the disease in one stage may not generalise to later stages.

Gender-specific effects of an augmented written emotional disclosure intervention on posttraumatic, depressive, and HIV-disease-related outcomes: a randomized, controlled trial

OBJECTIVE

Trauma histories and symptoms of PTSD occur at very high rates in people with HIV and are associated with poor disease management and accelerated disease progression. The authors of this study examined the efficacy of a brief written trauma disclosure intervention on posttraumatic stress, depression, HIV-related physical symptoms, and biological markers of HIV disease progression.

METHOD

HIV-infected men and women were randomized to four 30-min expressive writing sessions in either a treatment (trauma writing) or an attention control (daily events writing) condition. The disclosure intervention augmented the traditional emotional disclosure paradigm with probes to increase processing by focusing on trauma appraisals, self-worth, and problem solving. Outcomes were assessed at baseline, 1-, 6-, and 12-month follow-up.

RESULTS

Hierarchical linear modeling (N = 244, intent-to-treat analyses) revealed no significant treatment effects for the group as a whole. Gender by treatment group interactions were significant such that women in the trauma-writing group had significantly reduced posttraumatic stress disorder (PTSD) symptoms (p = .017), depression (p = .009), and HIV-related symptoms (p = .022) compared with their controls. In contrast, men in the trauma-treatment condition did not improve more than controls on any outcome variables. Unexpectedly, men in the daily-event-writing control group had significantly greater reductions in depression then men in the trauma-writing group. Treatment effects were magnified in women when the analysis was restricted to those with elevated PTSD symptoms at baseline.

CONCLUSIONS

A brief (4-session) guided written emotional disclosure intervention resulted in significant and meaningful reductions in PTSD, depression, and physical symptoms for women with HIV, but not for men.

Are emotion regulation skills related to adjustment among people with chronic pain, independent of pain coping?

Although emotion regulation capacities have been linked to adjustment among people with chronic pain, researchers have yet to determine whether these capacities are related to functioning independent of established facets of pain coping. The present study was designed to address this gap. A sample 128 Australian adults with chronic pain (44 men, 84 women) completed self-report measures of adjustment (quality of life, negative affect, and pain-related disability), pain coping, and features of emotion regulation (emotion appraisal, perceived efficacy in emotion regulation, emotion utilization). Hierarchical multiple regression analyses indicated that efficacy in emotion regulation was related to quality of life and reduced negative affect even after statistically controlling for effects of other measures of adjustment, pain coping efficacy, and pain coping. Conversely, features of emotion regulation did not improve the prediction model for pain-related disability. Findings suggest emotion regulation capacities may have a unique role in the prediction of specific facets of adjustment among people with chronic pain.

The match-mismatch model of emotion processing styles and emotion regulation strategies in fibromyalgia

OBJECTIVE

Individuals differ in their style of processing emotions (e.g., experiencing affects intensely or being alexithymic) and their strategy of regulating emotions (e.g., expressing or reappraising). A match-mismatch model of emotion processing styles and emotion regulation strategies is proposed and tested. This model specifies that for people high on affect intensity, emotion expression is more adaptive than reappraisal, whereas for alexithymic people, reappraisal is more adaptive than expression. The present study tested this model in 403 women with fibromyalgia (mean age 46.5±12.3 years).

METHODS

In a cross-sectional design, we assessed affect intensity (Berkeley Expressivity Questionnaire), alexithymia (Toronto Alexithymia Scale-20), cognitive reappraisal (Emotion Regulation Questionnaire), and emotion expression (Emotional Approach Coping Scales), as well as the impact of fibromyalgia (Fibromyalgia Impact Questionnaire).

RESULTS

Multiple regression analyses with interaction terms indicated that among people high on affect intensity, emotion expression - but not cognitive reappraisal - was associated with less fibromyalgia impact. No support was found for the hypothesis that among alexithymic people, cognitive reappraisal would be more adaptive than emotion expression.

CONCLUSION

Findings suggest that for women with fibromyalgia who experience their emotions intensely, an emotional disclosure or expression intervention may be beneficial. This hypothesis requires verification in experimental studies.

The WRITTEN-HEART study (expressive writing for heart healing): rationale and design of a randomized controlled clinical trial of expressive writing in coronary patients referred to residential cardiac rehabilitation

BACKGROUND

Coronary heart disease (CHD) is typically associated with many cardiovascular risk factors (e.g., elevated blood pressure), low health-related quality of life, depression, anxiety and psychological stress. Expressive writing (EW) has shown beneficial effects on such variables in both people from the community and in patients with a variety of chronic illnesses. However, no study to date has evaluated the physical and psychological effects of the expressive writing procedure on coronary patients referred to cardiac rehabilitation (CR).

METHODS

The clinical effectiveness of a 2-week disease-related expressive writing procedure (writing about one's deepest thoughts and feelings regarding the experience with heart disease) compared with the standard writing task (writing about one's deepest thoughts and feelings about the most traumatic or negative event experienced in the life), a neutral writing condition (writing about the facts regarding heart disease and its treatment) and an empty control condition will be evaluated in a randomized controlled clinical trial (RCT) with repeated follow-up measurements at 3, 6 and 12 months after discharge from CR. The primary outcome is health-related quality of life (SF-12). Secondary outcome measures are depression (BDI-II), anxiety (BAI) and post-traumatic growth (PTGI). Furthermore, the study will explore the moderating effects of coping styles, type D personality, perceived emotional support and participants' evaluative ratings of the writing interventions on the main experimental effects in order to identify sub-groups of patients showing different results.

DISCUSSION

The WRITTEN-HEART study aims to explore and expand the frontiers of the expressive writing research enterprise by investigating the feasibility, safety and clinical efficacy of brief and cost-effective expressive writing interventions in patients with CHD referred to CR.

Pain and emotion: a biopsychosocial review of recent research

OBJECTIVE AND METHOD

Research on emotion and pain has burgeoned. We review the last decade's literature, focusing on links between emotional processes and persistent pain.

RESULTS

Neurobiological research documents the neural processes that distinguish affective from sensory pain dimensions, link emotion and pain, and generate central nervous system pain sensitization. Psychological research demonstrates that greater pain is related to emotional stress and limited emotional awareness, expression, and processing. Social research shows the potential importance of emotional communication, empathy, attachment, and rejection.

CONCLUSIONS

Emotions are integral to the conceptualization, assessment, and treatment of persistent pain. Research should clarify when to eliminate or attenuate negative emotions, and when to access, experience, and express them. Theory and practice should integrate emotion into cognitive-behavioral models of persistent pain.

Sustained pain reduction through affective self-awareness in fibromyalgia: a randomized controlled trial

BACKGROUND AND OBJECTIVE

Affect and how it is regulated plays a role in pain perception, maintenance of pain, and its resolution. This randomized, controlled trial evaluated an innovative affective self-awareness (ASA) intervention, which was designed to reduce pain and improve functioning in individuals with fibromyalgia.

PARTICIPANTS AND METHODS

Forty-five women with fibromyalgia were randomized to a manualized ASA intervention (n = 24) or wait-list control (n = 21). The intervention began with a one-time physician consultation, followed by 3 weekly, 2-h group sessions based upon a mind-body model of pain. Sessions focused on structured written emotional disclosure and emotional awareness exercises. Outcomes in both conditions were measured by a blinded assessor at baseline, post-intervention, and 6-month follow-up.

MEASURES

The primary outcome was pain severity (Brief Pain Inventory); secondary outcomes included tender-point threshold and physical function (SF-36 Physical Component Summary). Intent-to-treat analyses compared groups on outcomes using analysis of covariance and on the proportion of patients achieving ≥ 30% and ≥ 50% pain reduction at 6 months.

RESULTS

Adjusting for baseline scores, the intervention group had significantly lower pain severity (p < 0.001), higher self-reported physical function (p < 0.001), and higher tender-point threshold (p = 0.02) at 6 months compared to the control group. From baseline to 6 months, 45.8% of the ASA intervention group had ≥ 30% reduction in pain severity, compared to none of the controls (p < 0.001).

CONCLUSIONS

The affective self-awareness intervention improved pain, tenderness, and self-reported physical function for at least 6 months in women with fibromyalgia compared to wait-list control. This study suggests the value of interventions targeting emotional processes in fibromyalgia, although further studies should evaluate the efficacy of this intervention relative to active controls.

Cognitive adaptability as a moderator of expressive writing effects in an HIV sample

This study explored the effects of expressive writing on positive and negative outcomes related to perceived psychosocial and health status among persons with HIV. This was the first study to examine the moderating effects of cognitive adaptability--consisting of dispositional optimism coupled with perceived competence--on outcomes of expressive writing. Thirty-seven participants wrote about either traumatic experiences or trivial topics in four 20-min sessions. Dependent measures obtained at baseline were repeated 1 month later. Although no main effects for group were found, baseline levels of cognitive adaptability were differentially associated with changes in a positive outcomes index, and a pain and physical functioning index in those assigned to the two groups. No moderating effects of cognitive adaptability were found for changes in a negative outcomes index. Findings underscore the importance of identification of moderating variables in understanding the impact of expressive writing interventions among individuals with HIV or other conditions.

Are psychological treatments effective for fibromyalgia pain?

This article considers four broad classes of psychological techniques and their effects on fibromyalgia (FM) pain. A literature search identified 14 randomized controlled trials (RCTs) of cognitive-behavioral therapy (CBT) and operant-behavioral therapy (OBT), five relaxation RCTs, five biofeedback RCTs, five hypnotherapy RCTs, and two writing intervention RCTs. For psychoanalytic therapy in FM, no RCTs have been published. The highest effect sizes (r = 0.53-2.14) for pain reduction are found after CBT and OBT group treatments. Relaxation as a single treatment has not been proven useful. Hypnotherapy and writing intervention have demonstrated mild treatment effects, whereas psychological treatment is effective in FM pain. Considering the heterogeneity of FM, the promising effects of matched interventions such as CBT and OBT with pharmacotherapy, exercise, and other treatment domains require further research.

The connection between art, healing, and public health: a review of current literature

This review explores the relationship between engagement with the creative arts and health outcomes, specifically the health effects of music engagement, visual arts therapy, movement-based creative expression, and expressive writing. Although there is evidence that art-based interventions are effective in reducing adverse physiological and psychological outcomes, the extent to which these interventions enhance health status is largely unknown. Our hope is to establish a foundation for continued investigation into this subject and to generate further interest in researching the complexities of engagement with the arts and health.

Mindfulness and experiential avoidance as predictors and outcomes of the narrative emotional disclosure task

This randomized study examined whether narrative emotional disclosure improves mindfulness, experiential avoidance, and mental health, and how baseline levels of and changes in mindfulness and experiential avoidance relate to mental health. Participants (N=233) wrote repeated traumatic (experimental condition) or unemotional daily events narratives (control condition). Regression analyses showed neither condition nor gender effects on mental health or experiential avoidance at a 1-month follow-up, although the control condition significantly increased in one component of mindfulness. Decreased experiential avoidance (across conditions) and increased mindfulness (in the experimental condition) significantly predicted improved mental health. Narrative disclosure thus did not improve outcomes measured here. However, increasing mindfulness when writing narratives with traumatic content, and decreasing experiential avoidance regardless of writing content, was associated with improved mental health.

Intravenous micronutrient therapy (Myers' Cocktail) for fibromyalgia: a placebo-controlled pilot study

OBJECTIVES

Intravenous micronutrient therapy (IVMT), and specifically the Myers' Cocktail, is a popular approach for treating fibromyalgia syndrome (FMS) among complementary and alternative medicine practitioners, but its efficacy is uncertain. This trial assessed the feasibility, safety, and provided insights into the efficacy of this therapy.

DESIGN

This was a randomized, double-blind, placebo-controlled pilot study.

LOCATIONS

The study locations were an academic research center, teaching hospital, and affiliated Integrative Medicine Center in Derby, CT.

SUBJECTS

The subjects were 34 adults with American College of Rheumatology (ACR)-defined FMS.

INTERVENTION

Subjects were randomly assigned either to treatment (weekly infusions of IVMT) or to placebo (weekly infusions of lactated Ringer's solution) for 8 weeks.

OUTCOME MEASURES

Primary outcome was change in the Tender Point Index, assessed 8 and 12 weeks after initiation. Secondary measures included a Visual Analog Scale to assess global pain, and validated measures of physical function (Fibromyalgia Impact Questionnaire), mood (Beck Depression Index), and quality of life (Health Status Questionnaire 2.0).

RESULTS

Clinically significant improvements were noted (of a magnitude similar to other effective interventions). However, in part because of the high placebo response and the small sample size, no statistically significant differences were seen between groups, in any outcome measure, at 8 and 16 weeks. Statistically significant within-group differences were seen in both the intervention and placebo groups, demonstrating a treatment effect for both IVMT and placebo. At 8 weeks, the IVMT group experienced significantly improved tender points, pain, depression, and quality of life directly following treatment (all p < or = 0.02), while the placebo group experienced significantly improved tender points only (p < or = 0.05). The treatment effects of IVMT persisted at 4 weeks postintervention for tender points, pain, and quality of life, while placebo effects persisted only for tender points. A single minor adverse event was noted in one subject in the intervention group.

CONCLUSIONS

This first controlled pilot study established the safety and feasibility of treating FMS with IVMT. Most subjects experienced relief as compared to baseline, but no statistically significant differences were seen between IVMT and placebo. The efficacy of IVMT for fibromyalgia, relative to placebo, is as yet uncertain.

An experimental assessment of a Pennebaker writing intervention in primary insomnia

This study considers the role of pre-sleep cognitive arousal, worry, and inhibition in sleep onset difficulties. The Pennebaker writing task, which promotes emotional processing by asking people to write about their thoughts, worries, and emotions, has proven effective in several areas of health. Here, the paradigm's ability to reduce pre-sleep cognitive arousal (PSCA) and sleep onset latency (SOL) in people with insomnia was tested. Twenty-eight people with insomnia were randomized to three nights of Pennebaker writing or a control condition, following a one-night baseline. The outcomes of change over baseline at Day 4 in pre-sleep cognitive arousal and SOL were compared. Writing significantly reduced pre-sleep cognitive arousal on one out of two measures, but did not significantly reduce SOL.
