Acceptance and Commitment Therapy for Primary Headache Sufferers: A Randomized Controlled Trial of Efficacy

An Online Psychological Program for Adolescents and Young Adults With Headaches: Iterative Design and Rapid Usability Testing

BACKGROUND

Headache disorders are common, debilitating health problems. Cognitive-behavioral therapy (CBT) is recommended but rarely easily available. With the use of the internet and communication technologies among youth and young adults, these individuals could be self-trained in CBT skills. There is an increasing number of internet-based interventions for headaches, but there has been little research into the usability of these interventions because evaluating usability across the intervention development life cycle is costly. We developed an internet-based CBT program, the Specialized Program for Headache Reduction (SPHERE). While developing it, we aimed to improve SPHERE through rapid usability testing cycles.

OBJECTIVE

This study aims to presents a rapid and affordable usability testing approach that can be performed throughout the intervention development life cycle. This paper also provides evidence of the usability of SPHERE.

METHODS

We used the "think aloud" usability testing method based on Krug's approach to test user interaction within a lab setting. This was followed by a short posttest interview. We planned to test SPHERE with 3-5 participants testing the same part of the program each cycle. Both the design and development team and the research team actively participated in the usability testing process. Observers independently identified the top 3 usability issues, rated their severity, and conducted debriefing sessions to come to consensus on major issues and generate potential solutions.

RESULTS

The testing process allowed major usability issues to be identified and rectified rapidly before piloting SPHERE in a real-world context. A total of 2 cycles of testing were conducted. Of the usability issues encountered in cycles 1 and 2, a total of 68% (17/25) and 32% (12/38), respectively, were rated as major, discussed, and fixed.

CONCLUSIONS

This study shows that rapid usability testing is an essential part of the design process that improves program functionality and can be easy and inexpensive to undertake.

An ACT self-help intervention for adults with a visible difference in appearance: A pilot feasibility and acceptability randomized controlled study

Individuals living with a visible difference in appearance experience high levels of social anxiety, yet self-help interventions for this heterogeneous population are not available. We conducted a pilot trial of a novel Acceptance and Commitment Therapy (ACT) based self-help intervention.Individuals with anxiety about having a visible difference in appearance (n = 284) were randomized to an ACT-based four-week intervention (n = 145) or a waitlist control condition (n = 139). We collected pre and follow-up (four-weeks after the completion of the intervention) data. Primary outcomes included social anxiety and impairments in functioning. Psychological flexibility (PF) was also examined. ANCOVAs, controlling for pre scores, indicated significant improvements in functioning by the intervention group. No significant differences were observed for anxiety and PF between conditions at follow-up. Drop out was 68% for the intervention and 41% for the control group, with no differences in the groups in age, origin, gender, or type of visible difference. Participants in the intervention group found the intervention almost equally, useful (77%) and helpful (73%). An ACT-based self-help intervention can alleviate distress related to visible difference in appearance. More sophisticated designs are needed now, to collect idiographic and longitudinal data and examine personalized changes across time in this population.

Non-Pharmacological Treatment of Primary Headaches-A Focused Review

Headache disorders are a significant global health burden, leading to reduced quality of life. While vast pharmacological treatments are available, they may be associated with adverse effects or inadequate efficacy for some patients, therefore there is a need for exploring alternate treatment strategies. This review gives a brief explanation and evaluation of some established and emerging non-pharmacological approaches for headache management, focusing on nutraceuticals and diet, acupuncture, cognitive behavioral therapy (CBT), biofeedback, relaxation techniques, autogenic training, and neuromodulation. Special consideration is given to psychological interventions as they increase patient self-efficacy and provide strategies for managing chronic pain. Future research should focus on optimizing these therapies, identifying patient-specific factors influencing their effectiveness, and integrating them into holistic headache management strategies.

A meta-analytic review of acceptance-based interventions for migraine

OBJECTIVE

To determine the efficacy of acceptance and mindfulness-based interventions on migraine disability, medication use, and attack frequency.

BACKGROUND

Acceptance-based approaches to headache management are those in which individuals learn to mitigate the influence of pain-related experiences on their general functioning without controlling pain itself. Treatment approaches include acceptance and commitment therapy (ACT) and mindfulness-based practices. Both have shown promise in improving broad functioning and disability among individuals with headache. Despite a growing body of research examining acceptance-based interventions for headache broadly and migraine specifically, no meta-analytic review of ACT interventions for headache exists, and two meta-analytic reviews of mindfulness-based practices yielded conflicting results.

METHODS

The present study aimed to systematically and quantitatively review the literature related to the efficacy of acceptance-based interventions among adults with migraine. A multi-database search (PubMed/MEDLINE, Scopus, PsycINFO, and the Cochrane Central Register of Controlled Trials) identified clinical trials among individuals with migraine that compared structured ACT or mindfulness-based interventions to control treatment. Random-effects meta-analyses were performed using RevMan 5.4 meta-analytic software, and standardized mean differences (SMD) with 95% confidence intervals (CIs) quantified effect sizes on outcomes of disability, medication use, and headache frequency. Heterogeneity was quantified via I2 index and explored via subgroup analyses.

RESULTS

Acceptance-based interventions yielded significant improvements in disability (SMD = -0.38, 95% CI = -0.56 to -0.20; I2  = 25%, p = 0.20) but not in medication use (SMD = -0.25, 95% CI: -0.57 to 0.06; I2  = 0%, p = 0.82) or headache frequency (SMD = -0.16, 95% CI = -0.37 to 0.05; I2  = 0%, p = 0.73).

CONCLUSION

Results suggest that acceptance-based interventions are effective in improving disability among adults with migraine and are a viable non-pharmacological treatment option, in addition to well-established behavioral migraine management approaches, for patients seeking functional improvement.

Understanding the gaps in headache and migraine treatment with psychological and behavioral interventions: A narrative review

OBJECTIVE

In this narrative review, we summarize relevant literature pertaining to psychosocial risk factors for headache and migraine progression, current behavioral and psychological treatments, and consider promising treatments.

BACKGROUND

Headache and migraine are common and associated with significant burden and disability. Current treatments targeting psychosocial risk factors show modest outcomes and do not directly address the impact of early life adversity, including the development of maladaptive emotional processing. An intervention that could address these factors and include components of current evidence-based interventions may lead to improved outcomes.

METHODS

We searched PubMed and Google Scholar for articles through December 2022. Search terms included headache, migraine, psychological interventions, behavioral interventions, cognitive-behavioral therapy, mindfulness, psychiatric comorbidities, adverse childhood experiences, trauma, and emotional processing.

RESULTS

Trauma and childhood adversity show a correlation with headache and migraine progression. Developmental adversity and trauma interfere with adaptive emotional processing, which may worsen headache and migraine symptoms, while adaptive ways of experiencing emotions are shown to improve symptoms. Current behavioral and psychological interventions, such as cognitive-behavioral and mindfulness therapies, are effective treatments for headache, but they produce small to medium effect sizes and do not directly address the impact of trauma and emotional conflicts-common factors that contribute to chronicity and disability, especially among certain subpopulations of headache patients such as those with migraine. Thus, there exists a gap in current treatment.

CONCLUSION

There is a gap in headache and migraine treatment for those patients who have a history of trauma, childhood adversity, and maladaptive emotional processing. We suggest that an integrated psychological treatment that includes components of current evidence-based interventions and addresses gaps by focusing on processing trauma-related emotions may improve chronic and debilitating symptoms.

A Network Analysis Approach on the Psychological Flexibility/Inflexibility Model

Acceptance and Commitment Therapy (ACT) is purported to work via targeting six interrelated processes summarized as the Psychological Inflexibility/Psychological Flexibility (PI/PF) model. However, the theoretical structure and interconnections of this model have not been sufficiently explored. Lacking are examinations of the interrelations among its components. Network Analysis (NA) can model PI/PF as a system of interconnected variables. We aimed at exploring the role and associations of the PI/PF model's components using NA in two different samples and sets of scales, and compare its structure across sub-samples. Sample 1 consisted of 501 individuals, who completed an online battery of questionnaires including the Multidimensional Psychological Flexibility Inventory, and Sample 2 consisted of 428 people, who completed an online set of six ACT measures, each assessing a component of the PI/PF model. NA could not verify the six ACT dimensions as distinct components. Values and Committed Action components were found to be strongly associated and combined in a group in both sets of measures and samples. Interestingly, Acceptance and Defusion were not the most central components as purported in some ACT conceptualizations, whereas Self-as-Context had a key role on both sets of measures and its items were often merged with Present Moment Awareness items. No significant differences were found in the comparison of networks across different subsamples and sets of scales. After combining different sets of scales, the six ACT components could not be completely verified as distinct entities, which might reflect problems with the theoretical model, or with the scales used. All components had critical roles in the model, particularly Self-as-Context, which reflects the need to redirect research towards this understudied construct. Findings point towards considerations of a triflex instead of a hexaflex ACT model.

Overcoming challenges in adherence and engagement digital interventions: The development of the ALGEApp for chronic pain management

Despite the growing body of evidence for the effectiveness of clinic-based interventions in increasing daily functioning in individuals with chronic pain, many sufferers still remain untreated or inadequately treated. Digital psychological interventions have been proposed as a means to overcome many of the barriers to face-to-face treatment (e.g., access, mobility, transportation problems) with the aim to improve health care for persons with chronic conditions in the convenience of their own space and time (home care). The main challenge of digital interventions however, is low user engagement and adherence. Focusing on users' engagement during the design phase of a digital intervention development can increase adherence, effectiveness, and acceptability. The purpose of this paper is to illustrate how we leveraged a recently proposed four-dimensional framework with evidence-based best practices and recommendations to develop a new digital intervention for chronic pain management, called the ALGEApp. A detailed presentation of how ALGEApp was designed and developed to adopt the recommendations and how this can aid engagement within digital interventions is proposed.

The efficacy of acceptance and commitment therapy for chronic pain: A three-level meta-analysis and a trial sequential analysis of randomized controlled trials

The current study included randomized controlled trials (RCTs) to assess the benefits of Acceptance and commitment therapy (ACT) for chronic pain. Searches were conducted in Web of Science, PsycINFO, PubMed, Scopus, Cochrane Library, and Embase from inception until September 30, 2022. Thirty-three RCTs, including 2293 participants, were included. Small to medium effect sizes for pain intensity/physical function favoring ACT were found both at post-treatment (pain intensity: g = 0.44; physical function: g = 0.59) and follow-up (pain intensity: g = 0.34; physical function: g = 0.56). The effect sizes on psychological outcomes were significant at post-treatment (depression: g = 0.43; anxiety: g = 0.43; quality of life: g = 0.45) and follow-up (depression: g = 0.43; anxiety: g = 0.35; quality of life: g = 0.43). The results of the trial sequential analyses indicated that pooled estimates were unlikely to be incidental findings, as effects of multiple testing were controlled and power was adequate. Face-to-face ACT yielded significantly larger effects on physical outcomes than internet-delivered ACT. Participants with chronic headache and fibromyalgia showed greater benefit from ACT compared to those with non-specific pain or mixed pain. In addition, the longer the follow-up duration, the smaller the effect sizes for pain intensity/physical function at follow-up. The present meta-analysis suggests sufficient evidence for the significant benefits of ACT for people with chronic pain.

The effect of the COVID-19 pandemic on headache-related disability among young adults with migraine

OBJECTIVE

The present study aimed to explore the relationship between the COVID-19 pandemic and headache-related disability among a sample of young adults with migraine.

BACKGROUND

Comorbid psychological symptoms compound migraine-related disability. Due to COVID-19 pandemic procedures, many students experienced institutional closures and corresponding increases in depression, stress, and anxiety. The present study sought to examine changes in headache-related disability before (Spring and Fall of 2019) and during (Fall of 2020 and Spring 2021) the COVID-19 pandemic and whether psychological symptoms mediated such changes.

METHODS

A cross-sectional study at a southern U.S. university assessed 365 individuals with migraine on headache and psychological variables, comparing those surveyed before COVID-19 with another group surveyed during the pandemic. The direct and indirect effects of COVID-19 status (pre- versus during COVID-19) on headache-related disability through depression, anxiety, and stress symptoms were assessed.

RESULTS

Statistically higher levels of depression, (M = 13.9 [SD = 12.2] vs. M = 8.7 [SD = 8.7], p < 0.001), anxiety (12.3 [10.0] vs. 9.7 [8.2], p = 0.01), and stress symptoms (17.6 [10.2] vs. 13.2 [7.9], p < 0.001) were endorsed during the COVID-19 pandemic. The direct path from COVID-19 status to headache-related disability was significant and negative, c' = -1.6 (95% CI: -3.1, -0.1). Anxiety (b = 0.3 [95% CI: 0.01, 0.9]) and depression (b = 0.7 [95% CI: 0.07, 1.4]) symptoms acted as mediators of this relationship, rendering the total effect nonsignificant and negating the lowered disability observed during the pandemic. Only depression symptoms remained a significant mediator after controlling for headache frequency (b = 0.7 [95% CI: 0.09, 1.4]).

CONCLUSIONS

Increased depression and anxiety symptoms attenuated the improvements in disability associated with the pandemic. As such, interventions that address comorbid psychological symptoms may hold value in reducing headache-related disability and improving outcomes for young adults whose headache developed or worsened during the COVID-19 pandemic.

Outpatient Approach to Resistant and Refractory Migraine in Children and Adolescents: a Narrative Review

PURPOSE OF REVIEW

Migraine is one of the top reasons for consulting a pediatric neurologist. Although the majority of children and adolescents who receive evidence-based first-line interventions for migraine will improve substantially, a subset of patients develop resistant or refractory migraine.

RECENT FINDINGS

In this review, we summarize the level of evidence for a variety of acute and preventive treatment options to consider in children and adolescents with resistant or refractory migraine. We describe the level of evidence for interventional procedures (onabotulinumtoxinA injections, greater occipital and other nerve blocks), neuromodulation (single-pulse transcranial magnetic stimulation, external trigeminal nerve stimulation, remote electrical neuromodulation, and non-invasive vagal nerve stimulation), calcitonin gene-related peptide (CGRP) pathway antagonists (anti-CGRP monoclonal antibodies and gepants), psychological therapies, and manual therapies (acupuncture, craniosacral therapy, massage and physical therapy, and spinal manipulation).

The Role of Pain Inflexibility and Acceptance among Headache and Temporomandibular Disorders Patients

Temporomandibular disorders (TMD) and headache are complex. This study aims to assess the association between TMD, headache, and psychological dimensions such as psychological inflexibility and pain acceptance. The sample consisted of 120 participants following a non-probabilistic convenience sampling strategy through a direct invitation to the patients attending our facilities and their relatives (n = 61 diagnosed with headache, n = 34 diagnosed with TMD-headache, n = 25 control group). Diagnostic Criteria for Temporomandibular Disorders (DC-TMD), International Classification of Headache Disorders (ICHD-3 beta version), Chronic Pain Acceptance Questionnaire (CPAQ-8), and Psychological Inflexibility in Pain Scale (PIPS) were used as assessment tools. One-way ANOVA, multiple regression analysis (MRA), and the Johnson-Neyman approach were run by IBM SPSS, version 27 (IBM^® Company, Chicago, IL, USA). The significance level was 0.05. One third of our sample presented with headache with TMD. Females were predominant. Males with headache, no systemic disease, less pain severity but higher frequency, living longer with the disease and having sensitive changes, showed higher pain acceptance. When headache occurs with TMD, women with higher education, no headache family history, less pain, and no motor changes showed higher pain acceptance. Patients with both conditions are more liable to have chronic pain and pain inflexibility. Pain intensity and willingness explain 50% of the psychological inflexibility in the headache group. In our sample, individuals suffering from both conditions show greater pain inflexibility, implicating more vivid suffering experiences, leading to altered daily decisions and actions. However, further studies are needed to highlight this possible association.

New generation psychological treatments in chronic pain

Chronic pain conditions are common and have a considerable impact on health and wellbeing. This impact can be reduced by cognitive behavioral therapy (CBT), the most commonly applied psychological approach to chronic pain. At the same time, CBT continues to develop, and now includes what is sometimes called "third wave" CBT. In this review, we examine the evidence for application of acceptance and commitment therapy (ACT), a principal example of this new wave or latest generation of treatment approaches, in people with chronic pain. We identified 25 randomized controlled trials of ACT for adults with chronic pain. Across the included trials, small to large effect sizes favoring ACT were reported for key outcomes including pain interference, disability, depression, and quality of life. Evidence from three studies provided some support for the cost effectiveness of ACT for chronic pain. Evidence also supported the mediating role of theoretically consistent processes of change (psychological flexibility) in relation to treatment outcomes. Investigation of moderators and predictors of outcomes was limited and inconsistent. In future, a greater focus on process based treatments is recommended. This should include continued identification of evidence based processes of change, and research methods more suited to understanding the experience and needs of individual people.

Psychedelics in the Treatment of Headache and Chronic Pain Disorders

The therapeutic potential of psychedelics in headache and chronic pain disorders is documented over decades of anecdotal and early investigational reports, which have paved the way for the first controlled studies of psilocybin and lysergic acid diethylamide (LSD) in these disorders. The reported lasting clinical effects after limited dosing with psychedelics present a novel means for disease management, but considerable further study will be required to address disease-specific treatments, uncover mechanism(s) of action, and verify safety. In this chapter, these topics are reviewed with particular attention to the neurobiological systems that offer potential sources of psychedelics' unique clinical effects in headache and pain.

Mechanisms of change in acceptance and commitment therapy for primary headaches

BACKGROUND

Despite the demonstrated effectiveness of behavioural headache interventions, it is not yet known which intervention processes account for treatment responses. Acceptance and commitment therapy (ACT), an emerging behavioural intervention for headaches, proposes psychological flexibility (PF) processes as the mechanisms via which intervention change occurs. This is the first study examining these processes of change variables on headache-related disability and quality of life (treatment outcome).

METHODS

Data originated from a Randomized Clinical Trial evaluating the efficacy of ACT for primary headaches. Ninety-four individuals with primary headaches (M = 43 y; 84% females; M headache frequency/month = 9.30) were randomized to either an ACT-based or a Wait-list control group (N = 47 in each). Participants completed questionnaires related to their headache experiences and PF processes at pre- (T1), post-treatment (T2), and 3-month follow-up (T3).

RESULTS

Following a bootstrapped cross product of coefficients approach, results demonstrated mediating effects of headache acceptance, cognitive defusion, avoidance of headache, and mindfulness in the ACT group compared to control on parameters of headache-related disability and quality of life at post and 3-month follow-ups.

CONCLUSIONS

These findings demonstrate that changes in certain PF processes lower disability and improve quality of life in headache sufferers, supporting that ACT works via its proposed mechanisms of change. Interventions for headache management may be optimized if they target increases in headache acceptance, defusion from thoughts, and mindfulness.

SIGNIFICANCE

Psychological flexibility (PF) guides the ACT approach, an emerging behavioral headache intervention that focuses on optimizing head pain adjustment via flexible responses to pain. It targets at increasing daily functioning rather than preventing or controlling headache episodes. Pain acceptance, cognitive defusion, and mindfulness act as processes of functional change in ACT, lowering disability and increasing daily functioning and quality of life. These components can upgrade the established effectiveness of behavioral headache interventions with personalized, modularized therapeutic targets that can help headache sufferers re-establish optimal daily functioning even in fluctuating and persistent headache episodes.

The American Headache Society Consensus Statement: Update on integrating new migraine treatments into clinical practice

OBJECTIVE

To incorporate recent research findings, expert consensus, and patient perspectives into updated guidance on the use of new acute and preventive treatments for migraine in adults.

BACKGROUND

The American Headache Society previously published a Consensus Statement on the use of newly introduced treatments for adults with migraine. This update, which is based on the expanded evidence base and emerging expert consensus concerning postapproval usage, provides practical recommendations in the absence of a formal guideline.

METHODS

This update involved four steps: (1) review of data about the efficacy, safety, and clinical use of migraine treatments introduced since the previous Statement was published; (2) incorporation of these data into a proposed update; (3) review and commentary by the Board of Directors of the American Headache Society and patients and advocates associated with the American Migraine Foundation; (4) consideration of these collective insights and integration into an updated Consensus Statement.

RESULTS

Since the last Consensus Statement, no evidence has emerged to alter the established principles of either acute or preventive treatment. Newly introduced acute treatments include two small-molecule calcitonin gene-related peptide (CGRP) receptor antagonists (ubrogepant, rimegepant); a serotonin (5-HT1F ) agonist (lasmiditan); a nonsteroidal anti-inflammatory drug (celecoxib oral solution); and a neuromodulatory device (remote electrical neuromodulation). New preventive treatments include an intravenous anti-CGRP ligand monoclonal antibody (eptinezumab). Several modalities, including neuromodulation (electrical trigeminal nerve stimulation, noninvasive vagus nerve stimulation, single-pulse transcranial magnetic stimulation) and biobehavioral therapy (cognitive behavioral therapy, biofeedback, relaxation therapies, mindfulness-based therapies, acceptance and commitment therapy) may be appropriate for either acute and/or preventive treatment; a neuromodulation device may be appropriate for acute migraine treatment only (remote electrical neuromodulation).

CONCLUSIONS

The integration of new treatments into clinical practice should be informed by the potential for benefit relative to established therapies, as well as by the characteristics and preferences of individual patients.

Effectiveness of Acceptance and Commitment Therapy in Central Pain Sensitization Syndromes: A Systematic Review

OBJECTIVES

Acceptance and commitment therapy (ACT) is considered by the American Psychological Association as an evidence-based treatment for a variety of disorders, including chronic pain. The main objective of the present systematic review was to determine the effectiveness of ACT in patients with central pain sensitization syndromes (CPSS).

METHODS

This systematic review was conducted according to the guidelines of the Cochrane Collaboration and PRISMA statements. The protocol was registered in advance in the Prospective Register of Systematic Reviews (PROSPERO) international database. The selected articles were evaluated using the Cochrane risk of bias (ROB) assessment tool. The PubMed, Scopus, and Web of Science databases were searched.

RESULTS

The literature search identified 21 studies (including investigations of fibromyalgia syndrome, irritable bowel syndrome, and migraine) eligible for the systematic review. There were no studies regarding the effectiveness of ACT for chronic tension-type headache (CTTH), interstitial cystitis (IC), or temporomandibular disorder (TMD). The evaluation of ROB showed that 12 of the selected studies were of low quality, 5 were of moderate quality, and 4 were high quality. ACT reduces some clinical symptoms, such as anxiety, depression, and pain. This positive effect of ACT might be mediated by pain acceptance, psychological flexibility, optimism, self-efficacy, or adherence to values. ACT showed better results in comparison to non-intervention (e.g., "waiting list") conditions, as well as pharmacological and psychoeducational interventions. It is not entirely clear whether extended ACT treatments are more advantageous than briefer interventions.

CONCLUSIONS

There are few studies about the effectiveness of ACT on CPSS. However, ACT seems to reduce subjective CPSS symptoms and improve the health-related quality of life of these patients. The absence of studies on the effectiveness of ACT in CTTH, IC, and TMD, indicate the pressing need for further ACT studies in these CPSS.

Nutraceuticals and Behavioral Therapy for Headache

PURPOSE OF REVIEW

Headache affects and disables at least 1 billion people worldwide. Patients and providers seek new therapies to relieve headache without the side effects and financial burden of current treatments. This narrative review highlights recent treatment advances in integrative headache medicine: nutraceuticals and behavioral therapies.

RECENT FINDINGS

Growing use of complementary and alternative medicine (CAM) therapies for headache (riboflavin, coenzyme Q10, magnesium, vitamin D, melatonin) alongside mainstream treatments is increasing with improving evidence of quality, safety, and tolerability. Increasing interest in medical cannabis is tempered by lack of evidence regarding safety and efficacy. Behavioral therapies including cognitive behavioral therapy (CBT), biofeedback, mindfulness-based stress reduction (MBSR), and acceptance and commitment therapy (ACT) improve patient resiliency and self-efficacy outcomes and reduce disability. The body of evidence for nutraceutical and behavioral CAM interventions for headache continues to grow and improve in quality. Providers and patients should educate themselves regarding CAM therapies as part of integrative headache management. Future studies should examine combinatorial trials of CAM therapies against current standards of headache care.
