Acceptance & Commitment Therapy for ME/CFS (Chronic Fatigue Syndrome) – A feasibility study

'Welcome to my world': a thematic analysis of the lived experiences of people with Myalgic Encephalomyelitis during the UK COVID-19 lockdown

OBJECTIVES

We explore the experiences of people with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (pwME/CFS) during the first UK COVID-19 lockdown period. We specifically probe perceived commonalities and departures in experience between government- and health-imposed lockdowns, application of coping strategies for social isolation, and predictions for inclusion of the chronically ill in post-pandemic society.

METHODS AND MEASURES

Thirty semi-structured interviews were conducted in pwME/CFS between June - July, 2020. Responses were qualitatively analysed using an experiential, thematic framework.

RESULTS

While participants reported enhancements in digital accessibility during lockdown, they perceived this as an unintentional benefit from changes designed to cater universally. Similarly, their expectation was that the general population's limited experience of restriction would not engender greater understanding for those who would continue to experience health-imposed lockdowns, post-pandemic. Participants described numerous strategies for coping with restriction and isolation, developed during prior health-imposed lockdowns and applied to this novel circumstance, highlighting the presence of acceptance and resilience in the sample.

CONCLUSIONS

Our findings suggest that future work may fruitfully examine whether our participant's predictions for post-pandemic societal inclusion have been met, and how resilience and acceptance might be developed and nurtured in chronically ill populations through times of adversity.

Online acceptance and commitment therapy (iACT) for adults with persistent physical symptoms - 3-month follow-up study of a randomized controlled trial

OBJECTIVE

Persistent physical symptoms (PPS) represent a major health problem affecting daily functioning. This RCT aimed to examine whether a guided Internet-based treatment based on acceptance and commitment therapy (ACT) provided additional benefits compared to Treatment as Usual (TAU) in reducing somatic complaints and psychological distress in adults with PPS.

METHODS

A total of 103 adults with PPS related to indoor environments, chronic fatigue or both conditions were assigned to receive either either a 14-week intervention (video-based case conceptualization + Internet-based ACT) combined with TAU (iACT + TAU; n = 50) or TAU alone (n = 53). Somatic symptoms, depression, anxiety, insomnia, and psychological flexibility were assessed from pre-intervention to a 3-month follow-up. Additionally, the association between changes in psychological flexibility from pre- to post-intervention and changes in symptoms from pre to 3-month follow-up was explored. Analyses were conducted using a multigroup method with full information maximum likelihood estimator.

RESULTS

The results revealed a significant interaction effect, indicating reductions in somatic symptoms and symptoms of depression and anxiety with moderate to large between-group effects (d = 0.71-1.09). No significant interaction effect was observed in insomnia and measures of psychological flexibility.

CONCLUSION

Internet-based ACT, when combined with Treatment as Usual, demonstrated efficacy for individuals with PPS associated with indoor environments and chronic fatigue. These findings are pertinent for primary healthcare providers, suggesting that the current treatment model could serve as a low-threshold first-line treatment option.

'I became more aware of my actions'-A qualitative longitudinal study of a health psychological group intervention for patients with myalgic encephalomyelitis/chronic fatigue syndrome

OBJECTIVES

To explore myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) patients' experiences of a health psychological group intervention and its usefulness, non-usefulness or harmfulness for illness management and adjustment.

DESIGN

A qualitative longitudinal study using inductive content analysis.

METHODS

Semistructured interviews were conducted with 10 adults. Interviews were conducted before the 16-week intervention, immediately after its completion, and at 3 months after completion.

RESULTS

Participants reported that the intervention was useful and not harmful. The model improved their ability to cope with ME/CFS by providing them with useful information about the illness along with peer support and professional guidance. Participants reported improved illness management and adjustment, which they perceived as an outcome of achieving new ways of thinking, feeling and acting.

CONCLUSIONS

Participants viewed the health psychological approach to group intervention as meeting their needs. To achieve better illness management and adjustment, more consideration should be given to supportive interactional processes with peers and healthcare professionals.

PATIENT OR PUBLIC CONTRIBUTION

The intervention was developed to meet patients' needs of finding ways to manage their illness. The research team consulted eight patients with ME/CFS and three clinical centres working with ME/CFS treatment and rehabilitation at the intervention planning stage. Their comments influenced the planning and content of the intervention as well as ethical issues that should be considered, such as potential harm to participants. All participants were informed about the theoretical foundations of the study and the principles guiding the intervention. Participants were not involved in the data analysis.

Effects of Acceptance and Commitment Therapy on fatigue interference and health-related quality of life among patients with advanced lung cancer: A pilot randomized controlled trial

Objective

The present study aimed to examine the feasibility and preliminary effects of Acceptance and Commitment Therapy (ACT) on fatigue interference and health-related quality of life in patients with advanced lung cancer.

Methods

In a single-blinded, parallel-group randomized controlled trial, 40 patients with advanced lung cancer were randomized to either the intervention group, which received the four-session individual ACT in 4 weeks, or the control group, which received usual care. The outcomes were evaluated at baseline and one week postintervention.

Results

Intervention feasibility and acceptability were established with a high attendance rate of 88.75% and a high retention rate of 75%. Approximately 95% of the participants reported satisfaction with the intervention. Despite the insignificant effects on fatigue interference, statistically significant interactions effects of ACT for health-related quality of life (P ​= ​0.001), cancer-related fatigue (P ​< ​0.001), depressive symptoms (P ​< ​0.001), anxiety (P ​< ​0.001), and distress (P ​= ​0.003) were noted.

Conclusions

This pilot trial supports the feasibility and acceptability of conducting ACT for patients with advanced lung cancer. The findings show the potential positive effects of ACT on health-related quality of life. Future studies with full-scale samples are recommended to evaluate the long-term effects of ACT on fatigue interference.

Mental and Physical Health Concerns in the Context of COVID-19: Opportunities and Applications for Behavioral Medicine

Numerous physical and mental health concerns have been documented in the context of COVID-19, and it is likely that patients, survivors, frontline health care workers, and other affected individuals will present to psychiatry for treatment. Behavioral medicine, an interdisciplinary field that is defined by a behavioral and biomedical conceptualization of clinical care, offers an opportunity for collaboration with psychiatry and other health care providers to meet the myriad needs resulting from the pandemic. This review summarizes a conceptual framework of behavioral medicine and clinical health psychology, COVID-19-related quality of life concerns that may be applicable to behavioral medicine referrals, clinical assessment directions, and intervention opportunities. The review combines both findings specific to COVID-19 and general behavioral medicine principles with an overall goal of providing a basic introduction to behavioral medicine practice, applications, and opportunities for management of medical and psychological symptoms.

Post-Covid-19 Syndrome: Improvements in Health-Related Quality of Life Following Psychology-Led Interdisciplinary Virtual Rehabilitation

Coronavirus disease 2019 (COVID-19) is increasingly recognized as having significant long-term impact on physical and mental health. The Primary Care Wellbeing Service (PCWBS) in Bradford District Care NHS Foundation Trust (BDCFT) is a psychology-led specialist interdisciplinary team of health professionals specializing in persistent physical symptoms (PPS) and Chronic Fatigue Syndrome (CFS)/Myalgic Encephalomyelitis (ME) with an emphasis on holistic integrated care. The PCWBS quickly recognized the risk of the long-term effects of COVID-19, particularly for social, health and care staff, and developed a 7-week virtual rehabilitation course which was piloted in October 2020. The “Recovering from COVID” course takes a whole system, biopsychosocial approach to understanding COVID-19 and post-viral fatigue (PVF) and is delivered by an interdisciplinary team consisting of a clinical psychologist, physiotherapist, occupational therapist, dietitian, speech and language therapist, assistant psychologist, and a personal support navigator with support from a team administrator. The course focuses on understanding PVF, sleep optimization, nutrition, swallowing, activity management, energy conservation, stress management, breathing optimization, managing setbacks, and signposting to appropriate resources and services. Since the pilot, PCWBS has delivered 7 courses to support over 200 people suffering from post-COVID-19 syndrome. One hundred and forty-nine individuals that enrolled on the “Recovering from COVID” course completed the EQ-5D-5L to assess Health-related quality of life (HRQoL) across 5 dimensions, including problems with mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Subsequently, 76 individuals completed these measures at the end of the rehabilitation course showing that patient ratings were significantly improved. In response to the NIHR recommendation for rapid evaluation of different service models for supporting people with post-COVID-19 syndrome, this data offers hope that rehabilitation is effective in reversing some of the problems faced by people living with the long-term effects of COVID-19.

Qualitative study of the acceptability and feasibility of acceptance and commitment therapy for adolescents with chronic fatigue syndrome

Background

Paediatric chronic fatigue syndrome/myalgic encephalomyelitis (CFS/ME) is disabling and relatively common. Although evidenced-based treatments are available, at least 15% of children remain symptomatic after one year of treatment. Acceptance and commitment therapy (ACT) is an alternative therapy option; however, little is known about whether it is an acceptable treatment approach. Our aim was to find out if adolescents who remain symptomatic with CFS/ME after 12 months of treatment would find ACT acceptable, to inform a randomised controlled trial (RCT) of ACT.

Methods

We recruited adolescents (diagnosed with CFS/ME; not recovered after one year of treatment; aged 11-17 years), their parent/carer and healthcare professionals (HCPs) from one specialist UK paediatric CFS/ME service. We conducted semi-structured interviews to explore barriers to recovery; views on current treatments; acceptability of ACT; and feasibility of an effectiveness RCT. Thematic analysis was used to identify patterns in data.

Results

Twelve adolescents, eleven parents and seven HCPs were interviewed. All participants thought ACT was acceptable. Participants identified reasons why ACT might be efficacious: pragmatism, acceptance and compassion are valued in chronic illness; values-focussed treatment provides motivation and direction; psychological and physical needs are addressed; normalising difficulties is a useful life-skill. Some adolescents preferred ACT to cognitive behavioural therapy as it encouraged accepting (rather than challenging) thoughts. Most adolescents would consent to an RCT of ACT but a barrier to recruitment was reluctance to randomisation. All HCPs deemed ACT feasible to deliver. Some were concerned patients might confuse 'acceptance' with 'giving up' and called for clear explanations. All participants thought the timing of ACT should be individualised.

Conclusions

All adolescents with CFS/ME, parents and HCPs thought ACT was acceptable, and most adolescents were willing to try ACT. An RCT needs to solve issues around randomisation and timing of the intervention.

Systematic Review of Mind-Body Interventions to Treat Myalgic Encephalomyelitis/Chronic Fatigue Syndrome

Background and Objectives: Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is a chronic condition distinguished by disabling fatigue associated with post-exertional malaise, as well as changes to sleep, autonomic functioning, and cognition. Mind-body interventions (MBIs) utilize the ongoing interaction between the mind and body to improve health and wellbeing. Purpose: To systematically review studies using MBIs for the treatment of ME/CFS symptoms. Materials and Methods: MEDLINE, EMBASE, CINAHL, PsycINFO, and Cochrane CENTRAL were searched (inception to September 2020). Interventional studies on adults diagnosed with ME/CFS, using one of the MBIs in comparison with any placebo, standard of care treatment or waitlist control, and measuring outcomes relevant to the signs and symptoms of ME/CFS and quality of life were assessed for inclusion. Characteristics and findings of the included studies were summarized using a descriptive approach. Results: 12 out of 382 retrieved references were included. Seven studies were randomized controlled trials (RCTs) with one including three reports (1 RCT, 2 single-arms); others were single-arm trials. Interventions included mindfulness-based stress reduction, mindfulness-based cognitive therapy, relaxation, Qigong, cognitive-behavioral stress management, acceptance and commitment therapy and isometric yoga. The outcomes measured most often were fatigue severity, anxiety/depression, and quality of life. Fatigue severity and symptoms of anxiety/depression were improved in nine and eight studies respectively, and three studies found that MBIs improved quality of life. Conclusions: Fatigue severity, anxiety/depression and physical and mental functioning were shown to be improved in patients receiving MBIs. However, small sample sizes, heterogeneous diagnostic criteria, and a high risk of bias may challenge this result. Further research using standardized outcomes would help advance the field.

Sick of the Sick Role: Narratives of What "Recovery" Means to People With CFS/ME

Little is known about what recovery means to those with chronic fatigue syndrome/myalgic encephalomyelitis, a poorly understood, disabling chronic health condition. To explore this issue, semi-structured interviews were conducted with patients reporting improvement (n = 9) and deterioration (n = 10) after a guided self-help intervention, and analyzed via "constant comparison." The meaning of recovery differed between participants-expectations for improvement and deployment of the sick role (and associated stigma) were key influences. While some saw recovery as complete freedom from symptoms, many defined it as freedom from the "sick role," with functionality prioritized. Others redefined recovery, reluctant to return to the lifestyle that may have contributed to their illness, or rejected the concept as unhelpful. Recovery is not always about eliminating all symptoms. Rather, it is a nexus between the reality of limited opportunities for full recovery, yet a strong desire to leave the illness behind and regain a sense of "normality."

Effectiveness of an ACT-based rehabilitation program for the treatment of chronic fatigue: Results from a 12-months longitudinal study

Acceptance and Commitment Therapy (ACT) is potentially effective for treating chronic fatigue. Given the paucity of studies on this topic, we aimed to assess long-term trajectories of primary (fatigue, quality of life and functional abilities) and secondary outcomes (anxious and depressive symptoms) of an ACT-based rehabilitation program for patients with chronic fatigue. Further, we examined if changes in potential process variables (psychological inflexibility, metacognitive beliefs, and cognitive and behavioral responses to symptoms) during ACT predicted change in all outcomes across follow-up. One-hundred ninety-five workers on sick leave (mean age: 43.61 ± 9.33 years; 80.5% females) with a diagnosis of chronic fatigue were enrolled in a manualized, 3.5-week intensive return-to-work rehabilitation program based on ACT. All completed a battery of questionnaires at pre-, post-treatment, 6 and 12 months follow-up. We found significant longitudinal changes in most primary and secondary outcomes from pre- up to 12 months follow-up. All process variables significantly decreased from pre- up to 12 months follow-up, and pre-to-post changes in fear avoidance beliefs were most often associated with a greater change in outcomes across follow-up. Depressive symptomatology showed a similar trajectory of change to fatigue, meaning that scores were correlated at each time point and tended to converge over time. This suggests that both symptoms influence each other substantially over a year following the treatment. Concluding, results lend support to the effectiveness of an ACT-based rehabilitation program for patients with chronic fatigue and provide preliminary evidence for the role of process variables and depressive symptomatology on subsequent change in outcomes.

The role of low-grade inflammation in ME/CFS (Myalgic Encephalomyelitis/Chronic Fatigue Syndrome) - associations with symptoms

BACKGROUND

Patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) often present with a range of flu-like symptoms resembling sickness behavior as well as widespread pain and concentration deficits. The aim of this study was to explore the association between inflammatory markers previously shown to be related to fatigue severity in ME/CFS and common ME/CFS symptoms post-exertional fatigue, impaired cognitive processing, musculoskeletal pain and recurrent flu-like symptoms, and the moderating effect of sex on these associations.

METHODS

53 adult patients diagnosed with ME/CFS at a specialist clinic were included in the study. Fasting blood plasma was analyzed using the Olink Proseek Multiplex Inflammation panel (β-NGF, CCL11, CXCL1, CXCL10, IL-6, IL-7, IL-8, IL-10, IL-18, TGF-α, TGF-β-1 and SCF) and BioRad Human Cytokine Type 1 assay (TNF-α). Participants rated the average severity of symptoms (0-10) based on the 2011 International Consensus Criteria of ME/CFS during a structured clinical interview. Associations between inflammatory markers and symptom severity were analyzed using bivariate correlations and moderated regression analyses bootstrapped with 5000 repetitions.

RESULTS AND CONCLUSIONS

Only β-NGF was associated with the fatigue severity measure. However, higher levels of CCL11, CXCL10, IL-7, TNF-α and TGF-β-1 were significantly associated with higher levels of impaired cognitive processing and musculoskeletal pain, and sex was a significant moderator for CXCL10, IL-7 and TGF-β-1. Future studies should investigate the relationship between inflammatory markers and key symptoms in ME/CFS in a longitudinal design in order to explore if and for whom low-grade inflammation may contribute to illness development.

Patients with ME/CFS (Myalgic Encephalomyelitis/Chronic Fatigue Syndrome) and chronic pain report similar level of sickness behavior as individuals injected with bacterial endotoxin at peak inflammation

Background

Chronic sickness behavior is implicated in ME/CFS (Myalgic Encephalomyelitis/Chronic Fatigue Syndrome) and chronic pain but the level of subjective sickness behavior in these conditions has not been investigated or compared to other clinical and non-clinical samples, or to the level in experimental inflammation. Furthermore, the relationship between sickness behavior and self-rated health and functioning is not known in patients with ME/CFS and chronic pain. The aim of the present study was to investigate how sickness behavior in patients with chronic conditions differs from that in individuals with experimental acute sickness, primary care patients, the general population and healthy subjects. In addition, we wanted to explore how sickness behavior is related to self-rated health and health-related functioning.

Methods

Sickness behavior was quantified using the sickness questionnaire (SicknessQ). Self-ratings were collected at one time-point in 6 different samples. Levels of sickness behavior in patients with ME/CFS (n ​= ​38) and patients with chronic pain (n ​= ​190) were compared to healthy subjects with lipopolysaccharide(LPS)-induced inflammation (n ​= ​29), primary care patients (n ​= ​163), individuals from the general population (n ​= ​155) and healthy subjects (n ​= ​48), using linear regression. Correlations and moderated regression analyses were used to investigate associations between sickness behavior and self-rated health and health-related functioning in ME/CFS, chronic pain and the general population.

Results

LPS-injected individuals (M ​= ​16.3), patients with ME/CFS (M ​= ​16.1), chronic pain (M ​= ​16.1) and primary care patients (M ​= ​10.7) reported significantly higher SicknessQ scores than individuals from the general population (M ​= ​5.4) and healthy subjects (M ​= ​3.6) all p's ​< ​0.001). In turn, LPS-injected individuals, patients with ME/CFS and chronic pain reported significantly higher SicknessQ scores than primary care patients (p's ​< ​0.01). Higher levels of sickness behavior were associated with poorer self-rated health and health-related functioning (p's ​< ​0.01), but less so in patients with ME/CFS and chronic pain than in individuals from the general population.

Conclusions

Patients with ME/CFS and chronic pain report similar high levels of sickness behavior; higher than primary care patients, and comparable to levels in experimental inflammation. Further study of sickness behavior in ME/CFS and chronic pain populations is warranted as immune-to-brain interactions and sickness behavior may be of importance for functioning as well as in core pathophysiological processes in subsets of patients.
