Summary

The goal of this research project is to evaluate if our well-researched behavior medicine treatment model for chronic pain, based on Acceptance and Commitment Therapy, is safe and effective in increasing quality of life and functioning also in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). To date there are no effective treatments for ME/CFS as the ethology and pathophysiology are unknown, while levels of functioning and quality of life as well as secondary effects such as depressive and anxiety symptoms indicate a highly affected patient population. As such, there is a need for behavior medicine approaches that aim to alleviate suffering and promote increases in quality of life for these patients. The aim of the present study is to do a preliminary evaluation of the safety, acceptability and efficacy of an ACT-based treatment protocol for ME/CFS. An additional aim is to explore potential mediators of change for the effect of treatment on disability.

Detailed description

Background Medical strategies alone appear insufficient to increase functioning and quality of life in ME/CFS. Cognitive behavioral therapy (CBT) is the only treatment approach with preliminary evidence of efficacy for improving functioning and quality of life. However, effect sizes are generally modest. Behavior medicine treatment approaches based on Acceptance \& Commitment Therapy (ACT) have gained increasing attention and research support within clinical trials for similar diagnoses (e.g. chronic pain, Fibromyalgia). Results from these areas illustrate the utility of this approach for individuals with somatic symptomatology. To date, the efficacy of ACT has not been evaluated for ME/CFS. Purpose The aims of this pilot study are to explore the utility of ACT and to evaluate the feasibility of the treatment model for patients with ME/CFS. Method Treatment program: 13 weekly to bi-weekly individual ACT sessions with a psychologist (10) and a physician (3) respectively. An open trial design is used, with assessments at pre-, mid- and post-treatment as well as at 3 and 6 months follow-up. Further, yearly follow-ups until 5-year follow-up are planned. Measures: History data, illness factors, psychological factors, functioning and quality of life. Patients: Consecutively recruited via referrals to a specialist treatment centre (n=40). Once patients have been found eligible and expressed interest in study participation they will be assessed by a psychologist and by a physician, via semi-structured interviews to confirm eligibility and to ensure that the patient meet the study criteria. Informed consent is obtained from all participants prior to the assessment. Statistical analysis: Evaluations of treatment effects are primarily based on intent-to-treat analyses. The statistical approach will primarily be based on linear multilevel modeling (LMM), which takes into account dependencies between repeated measures and differences between patients in pre-treatment status and treatment response (i.e. random effects modeling) and also provide means of handling missing data.

Type	Name	Description
BEHAVIORAL	Acceptance and Commitment Therapy (ACT)	The main target in ACT for ME/CFS (as for Fibromyalgia and Chronic pain in previous studies by our group) is to promote a shift of perspective in life from symptom reduction (when it does not work) to a valued life. As such it entails acceptance and exposure to discomfort, in order to lessen the effects of negative experiences (symptoms, emotions, thoughts) on behaviours in everyday life.
