Therapist effects in routine psychotherapy practice: an account from chronic fatigue syndrome

COPD-Related Fatigue: A Scoping Review

Millions of people worldwide have chronic obstructive pulmonary disease (COPD), and one of the most common and troublesome symptoms that must be managed is fatigue. While there are existing interventions to address COPD-related fatigue, not all patients experience benefit. A better understanding of the factors associated with COPD-fatigue could elucidate new approaches to address COPD-related fatigue, thereby offering relief to a greater number of patients. The purpose of this review was to identify the physiologic, psychologic, and situational factors associated with COPD-related fatigue. A total of four databases, PubMed, CINAHL, Scopus, and Google Scholar, were searched. Those that were peer reviewed, in English, and published between 2000 and 2021, were included in the review. A total of 25 articles were included in this scoping review. The following factors were related to fatigue in COPD: dyspnea, pain, anxiety, depression, and sleep. Fatigue is a debilitating symptom with factors influential to the symptom and outcomes. Research is indicated to explore targeted and personalized interventions addressing the factors related to fatigue to mitigate this widespread symptom.

Cognitive behavioural therapy for chronic fatigue and chronic fatigue syndrome: outcomes from a specialist clinic in the UK

OBJECTIVES

Cognitive behavioural therapy is commonly used to treat chronic fatigue syndrome and has been shown to be effective for reducing fatigue and improving physical functioning. Most of the evidence on the effectiveness of cognitive behavioural therapy for chronic fatigue syndrome is from randomised control trials, but there are only a few studies in naturalistic treatment settings. Our aim was to examine the effectiveness of cognitive behavioural therapy for chronic fatigue syndrome in a naturalistic setting and examine what factors, if any, predicted outcome.

DESIGN

Using linear mixed effects analysis, we analysed patients' self-reported symptomology over the course of treatment and at three-month follow-up. Furthermore, we explored what baseline factors were associated with improvement at follow-up.

SETTING

Data were available for 995 patients receiving cognitive behavioural therapy for chronic fatigue syndrome at an outpatient clinic in the UK.

PARTICIPANTS

Participants were referred consecutively to a specialist unit for chronic fatigue or chronic fatigue syndrome.

MAIN OUTCOME MEASURES

Patients were assessed throughout their treatment using self-report measures including the Chalder Fatigue Scale, 36-item Short Form Health Survey, Hospital Anxiety and Depression Scale and Global Improvement and Satisfaction.

RESULTS

Patients' fatigue, physical functioning and social adjustment scores significantly improved over the duration of treatment with medium to large effect sizes (|d| = 0.45-0.91). Furthermore, 85% of patients self-reported that they felt an improvement in their fatigue at follow-up and 90% were satisfied with their treatment. None of the regression models convincingly predicted improvement in outcomes with the best model being (R² = 0.137).

CONCLUSIONS

Patients' fatigue, physical functioning and social adjustment all significantly improved following cognitive behavioural therapy for chronic fatigue syndrome in a naturalistic outpatient setting. These findings support the growing evidence from previous randomised control trials and suggest that cognitive behavioural therapy could be an effective treatment in routine treatment settings.

Internet-Based Cognitive Behavioral Therapy for Chronic Fatigue Syndrome Integrated in Routine Clinical Care: Implementation Study

BACKGROUND

In a clinical trial, internet-based cognitive behavioral therapy (I-CBT) embedded in stepped care was established as noninferior to face-to-face cognitive behavioral therapy (CBT) for chronic fatigue syndrome (CFS). However, treatment effects observed in clinical trials may not necessarily be retained after implementation.

OBJECTIVE

This study aimed to investigate whether stepped care for CFS starting with I-CBT, followed by face-to-face CBT, if needed, was also effective in routine clinical care. Another objective was to explore the role of therapists' attitudes toward electronic health (eHealth) and manualized treatment on treatment outcome.

METHODS

I-CBT was implemented in five mental health care centers (MHCs) with nine treatment sites throughout the Netherlands. All patients with CFS were offered I-CBT, followed by face-to-face CBT if still severely fatigued or disabled after I-CBT. Outcomes were the Checklist Individual Strength, physical and social functioning (Short-Form 36), and limitations in daily functioning according to the Work and Social Adjustment Scale. The change scores (pre to post stepped care) were compared with a benchmark: stepped care from a randomized controlled trial (RCT) testing this treatment format. We calculated correlations of therapists' attitudes toward manualized treatment and eHealth with reduction of fatigue severity.

RESULTS

Overall, 100 CFS patients were referred to the centers. Of them, 79 started with I-CBT, 20 commenced directly with face-to-face CBT, and one did not start at all. After I-CBT, 48 patients met step-up criteria; of them, 11 stepped up to face-to-face CBT. Increase in physical functioning (score of 13.4), social functioning (20.4), and reduction of limitations (10.3) after stepped care delivered in routine clinical care fell within the benchmarks of the RCT (95% CIs: 12.8-17.6; 25.2-7.8; and 7.4-9.8, respectively). Reduction of fatigue severity in the MHCs was smaller (12.6) than in the RCT (95% CI 13.2-16.5). After I-CBT only, reduction of fatigue severity (13.2) fell within the benchmark of I-CBT alone (95% CI 11.1-14.2). Twenty therapists treated between one and 18 patients. Therapists were divided into two groups: one with the largest median reduction of fatigue and one with the smallest. Patients treated by the first group had a significantly larger reduction of fatigue severity (15.7 vs 9.0; t=2.42; P=.02). There were no (statistically significant) correlations between therapists' attitudes and reduction in fatigue.

CONCLUSIONS

This study is one of the first to evaluate stepped care with I-CBT as a first step in routine clinical care. Although fatigue severity and disabilities were reduced, reduction of fatigue severity appeared smaller than in the clinical trial. Further development of the treatment should aim at avoiding dropout and encouraging stepping up after I-CBT with limited results. Median reduction of fatigue severity varied largely between therapists. Further research will help understand the role of therapists' attitudes in treatment outcome.

A systematic review of therapist effects: A critical narrative update and refinement to review

OBJECTIVE

To review the therapist effects literature since Baldwin and Imel's (2013) review.

METHOD

Systematic literature review of three databases (PsycINFO, PubMed and Web of Science) replicating Baldwin and Imel (2013) search terms. Weighted averages of therapist effects (TEs) were calculated, and a critical narrative review of included studies conducted.

RESULTS

Twenty studies met inclusion criteria (3 RCTs; 17 practice-based) with 19 studies using multilevel modeling. TEs were found in 19 studies. The TE range for all studies was 0.2% to 29% (weighted average = 5%). For RCTs, 1%-29% (weighted average = 8.2%). For practice-based studies, 0.2-21% (weighted average = 5%). The university counseling subsample yielded a lower TE (2.4%) than in other groupings (i.e., primary care, mixed clinical settings, and specialist/focused settings). Therapist sample sizes remained lower than recommended, and few studies appeared to be designed specifically as TE studies, with too few examples of maximising the research potential of large routine patient datasets.

CONCLUSIONS

Therapist effects are a robust phenomenon although considerable heterogeneity exists across studies. Patient severity appeared related to TE size. TEs from RCTs were highly variable. Using an overall therapist effects statistic may lack precision, and TEs might be better reported separately for specific clinical settings.

'It feels sometimes like my house has burnt down, but I can see the sky': A qualitative study exploring patients' views of cognitive behavioural therapy for chronic fatigue syndrome

OBJECTIVES

Cognitive behavioural therapy (CBT) is currently a first-line treatment for chronic fatigue syndrome (CFS). Even though the results from trials are promising, there is variability in patient outcomes. The aim of this study was to explore the experiences of patients with CFS who undertook CBT at a specialist service for CFS.

DESIGN

This was a qualitative study.

METHODS

Thirteen patients with CFS, approaching the end of CBT, participated in semi-structured interviews. In addition, participants were asked to rate their satisfaction with CBT and perceived level of improvement. The data were analysed using inductive thematic analysis.

RESULTS

The majority of participants were satisfied with treatment and reported marked improvements. This was evident from the ratings and corroborated by the qualitative data, yet recovery was in general incomplete. Participants often disclosed mixed feelings towards CBT prior to its start. Behavioural aspects of treatment were found useful, while participants were more ambivalent towards the cognitive aspects of treatment. The tailored nature of CBT and therapist contact were important components of treatment, which provided participants with support and validation. Engagement and motivation were crucial for participants to benefit from CBT, as well as the acceptance of a bio-psychosocial model of CFS. Illness beliefs around CFS were also discussed throughout the interviews, possibly impeding engagement with therapy.

CONCLUSIONS

The results suggest that various factors may moderate the effectiveness of CBT, and a greater understanding of these factors may help to maximize benefits gained from CBT. Statement of contribution What is already known on this subject? CBT is effective in reducing CFS symptoms, but not all patients report marked improvements following treatment. Predictors of outcome have been explored in the literature. Few studies have looked at the experience of adult patients with CFS who have had CBT. What does this study add? Findings provide insights as to why variability in CBT-related improvements exists. Beliefs about CFS and CBT may shape engagement and consequently contribute to post-treatment outcomes. Flexibility and sensitivity are necessary from therapists throughout treatment to ensure full engagement.

A feasibility randomised controlled trial of the DECIDE intervention: dementia carers making informed decisions

SUMMARY

Family carers report high levels of decisional conflict when deciding whether their relative with dementia can continue to be cared for in their own home. We tested, in a feasibility randomised controlled trial, the first decision aid (the DECIDE manual) aiming to reduce such conflict. Twenty family carers received the DECIDE intervention, and 21 received usual treatment. The intervention group had reduced decisional conflict compared with controls (mean difference -11.96, 95% confidence interval -20.10 to -3.83, P=0.005). All carers receiving the intervention completed and valued it, despite some still reporting difficulties with family conflict and problems negotiating services.

Therapist Effects and the Impact of Early Therapeutic Alliance on Symptomatic Outcome in Chronic Fatigue Syndrome

Few studies have examined therapist effects and therapeutic alliance (TA) in treatments for chronic fatigue syndrome (CFS). Therapist effects are the differences in outcomes achieved by different therapists. TA is the quality of the bond and level of agreement regarding the goals and tasks of therapy. Prior research suffers the methodological problem that the allocation of therapist was not randomized, meaning therapist effects may be confounded with selection effects. We used data from a randomized controlled treatment trial of 296 people with CFS. The trial compared pragmatic rehabilitation (PR), a nurse led, home based self-help treatment, a counselling-based treatment called supportive listening (SL), with general practitioner treatment as usual. Therapist allocation was randomized. Primary outcome measures, fatigue and physical functioning were assessed blind to treatment allocation. TA was measured in the PR and SL arms. Regression models allowing for interactions were used to examine relationships between (i) therapist and therapeutic alliance, and (ii) therapist and average treatment effect (the difference in mean outcomes between different treatment conditions). We found no therapist effects. We found no relationship between TA and the average treatment effect of a therapist. One therapist formed stronger alliances when delivering PR compared to when delivering SL (effect size 0.76, SE 0.33, 95% CI 0.11 to 1.41). In these therapies for CFS, TA does not influence symptomatic outcome. The lack of significant therapist effects on outcome may result from the trial's rigorous quality control, or random therapist allocation, eliminating selection effects. Further research is needed.

COgnitive behavioural therapy vs standardised medical care for adults with Dissociative non-Epileptic Seizures (CODES): a multicentre randomised controlled trial protocol

BACKGROUND

The evidence base for the effectiveness of psychological interventions for patients with dissociative non-epileptic seizures (DS) is currently extremely limited, although data from two small pilot randomised controlled trials (RCTs), including from our group, suggest that Cognitive Behavioural Therapy (CBT) may be effective in reducing DS occurrence and may improve aspects of psychological status and psychosocial functioning.

METHODS/DESIGN

The study is a multicentre, pragmatic parallel group RCT to evaluate the clinical and cost-effectiveness of specifically-tailored CBT plus standardised medical care (SMC) vs SMC alone in reducing DS frequency and improving psychological and health-related outcomes. In the initial screening phase, patients with DS will receive their diagnosis from a neurologist/epilepsy specialist. If patients are eligible and interested following the provision of study information and a booklet about DS, they will consent to provide demographic information and fortnightly data about their seizures, and agree to see a psychiatrist three months later. We aim to recruit ~500 patients to this screening stage. After a review three months later by a psychiatrist, those patients who have continued to have DS in the previous eight weeks and who meet further eligibility criteria will be told about the trial comparing CBT + SMC vs SMC alone. If they are interested in participating, they will be given a further booklet on DS and study information. A research worker will see them to obtain their informed consent to take part in the RCT. We aim to randomise 298 people (149 to each arm). In addition to a baseline assessment, data will be collected at 6 and 12 months post randomisation. Our primary outcome is monthly seizure frequency in the preceding month. Secondary outcomes include seizure severity, measures of seizure freedom and reduction, psychological distress and psychosocial functioning, quality of life, health service use, cost effectiveness and adverse events. We will include a nested qualitative study to evaluate participants' views of the intervention and factors that acted as facilitators and barriers to participation.

DISCUSSION

This study will be the first adequately powered evaluation of CBT for this patient group and offers the potential to provide an evidence base for treating this patient group.

The planning, implementation and publication of a complex intervention trial for chronic fatigue syndrome: the PACE trial

The PACE trial was a four-arm trial of specialist medical care, compared with specialist medical care with a supplementary therapy: adaptive pacing therapy, cognitive-behavioural therapy or graded exercise therapy, for patients with chronic fatigue syndrome. The trial found that both cognitive-behavioural and graded exercise therapies were more effective than either of the other two treatments in reducing fatigue and improving physical disability. This paper describes the design, conduct and main results of the trial, along with a description of the challenges that had to be overcome in order to produce clear answers to the clinically important questions the trial posed.

Heterogeneity in patient-reported outcomes following low-intensity mental health interventions: a multilevel analysis

Background

Variability in patient-reported outcomes of psychological treatments has been partly attributed to therapists – a phenomenon commonly known as therapist effects. Meta-analytic reviews reveal wide variation in therapist-attributable variability in psychotherapy outcomes, with most studies reporting therapist effects in the region of 5% to 10% and some finding minimal to no therapist effects. However, all except one study to date have been conducted in high-intensity or mixed intervention groups; therefore, there is scarcity of evidence on therapist effects in brief low-intensity psychological interventions.

Objective

To examine therapist effects in low-intensity interventions for depression and anxiety in a naturalistic setting.

Data and Analysis

Session-by-session data on patient-reported outcome measures were available for a cohort of 1,376 primary care psychotherapy patients treated by 38 therapists. Outcome measures included PHQ-9 (sensitive to depression) and GAD-7 (sensitive to general anxiety disorder) measures. Three-level hierarchical linear modelling was employed to estimate therapist-attributable proportion of variance in clinical outcomes. Therapist effects were evaluated using the intra-cluster correlation coefficient (ICC) and Bayesian empirical predictions of therapist random effects. Three sensitivity analyses were conducted: 1) using both treatment completers and non-completers; 2) a sub-sample of cases with baseline scores above the conventional clinical thresholds for PHQ-9 and GAD-7; and 3) a two-level model (using patient-level pre- and post-treatment scores nested within therapists).

Results

The ICC estimates for all outcome measures were very small, ranging between 0% and 1.3%, although most were statistically significant. The Bayesian empirical predictions showed that therapist random effects were not statistically significantly different from each other. Between patient variability explained most of the variance in outcomes.

Conclusion

Consistent with the only other study to date in low intensity interventions, evidence was found to suggest minimal to no therapist effects in patient-reported outcomes. This draws attention to the more prominent source of variability which is found at the between-patient level.

Mechanisms of change underlying the efficacy of cognitive behaviour therapy for chronic fatigue syndrome in a specialist clinic: a mediation analysis

BACKGROUND

Several randomized controlled trials (RCTs) have shown that cognitive behavioural psychotherapy (CBT) is an efficacious treatment for chronic fatigue syndrome (CFS). However, little is known about the mechanisms by which the treatment has its effect. The aim of this study was to investigate potential mechanisms of change underlying the efficacy of CBT for CFS. We applied path analysis and introduce novel model comparison approaches to assess a theoretical CBT model that suggests that fearful cognitions will mediate the relationship between avoidance behaviour and illness outcomes (fatigue and social adjustment).

METHOD

Data from 389 patients with CFS who received CBT in a specialist service in the UK were collected at baseline, at discharge from treatment, and at 3-, 6- and 12-month follow-ups. Path analyses were used to assess possible mediating effects. Model selection using information criteria was used to compare support for competing mediational models.

RESULTS

Path analyses were consistent with the hypothesized model in which fear avoidance beliefs at the 3-month follow-up partially mediate the relationship between avoidance behaviour at discharge and fatigue and social adjustment respectively at 6 months.

CONCLUSIONS

The results strengthen the validity of a theoretical model of CBT by confirming the role of cognitive and behavioural factors in CFS.

Assessing the influence of treating therapist and patient prognostic factors on recovery from axial pain

BACKGROUND

Limited research exists regarding the influence of a treating physical therapist on patient recovery (deemed therapist effects). Recent randomized clinical trials data provide an indication of small therapist effects for manual therapy; however, the extent to which therapist effects exist in the average outpatient facility is not clear. Moreover, patient-related prognostic factors, like fear-avoidance or pain duration, are important to consider since these may also influence the extent of therapist effects.

OBJECTIVE

To assess therapist effects and the influence of patient prognostic factors on recovery from axial pain in an outpatient orthopedic physical therapy facility.

METHODS

Clinical data were collected from consecutive patients with musculoskeletal neck and low back pain. Patient outcomes included pain intensity (visual analog scale) and functional measure (CareConnections functional outcomes index) scores. Therapist effects estimates and the influence of intake fear-avoidance (fear-avoidance beliefs questionnaire) and pain duration (days) were examined using multilevel linear or regression modeling.

RESULTS

A total of 258 patients (160 females; mean age 46.4±14.9 years) completed physical therapy and the required outcome measures. Five physical therapists (1-13 years of experience, mean 5.8 years) provided treatment. Therapists effects did not exist for discharge pain intensity or function after accounting for intake scores (P > 0.05). Further, therapist experience did not influence patient outcomes. Patient prognostic factors of fear-avoidance and pain duration did not influence therapists effects on the same patient outcome measures (P > 0.05).

DISCUSSION

Preliminary findings suggest that there are no major differences in patient outcome based on either the individual therapist (therapist effect) or therapist experience in this type of PT setting. Established prognostic factors had no influence on therapist effects for this cohort. Future analyses should consider intrinsic therapist factors (beliefs, equipoise), specific treatment parameters (dosage, type), and other patient prognostic factors (psychological, age, expectation, satisfaction) to further elucidate the influence of therapist effects.

Implementation of cognitive therapy for PTSD in routine clinical care: effectiveness and moderators of outcome in a consecutive sample

Objective

Trauma-focused psychological treatments are recommended as first-line treatments for Posttraumatic Stress Disorder (PTSD), but clinicians may be concerned that the good outcomes observed in randomized controlled trials (RCTs) may not generalize to the wide range of traumas and presentations seen in clinical practice. This study investigated whether Cognitive Therapy for PTSD (CT-PTSD) can be effectively implemented into a UK National Health Service Outpatient Clinic serving a defined ethnically mixed urban catchment area.

Method

A consecutive sample of 330 patients with PTSD (age 17–83) following a wide range of traumas were treated by 34 therapists, who received training and supervision in CT-PTSD. Pre and post treatment data (PTSD symptoms, anxiety, depression) were collected for all patients, including dropouts. Hierarchical linear modeling investigated candidate moderators of outcome and therapist effects.

Results

CT-PTSD was well tolerated and led to very large improvement in PTSD symptoms, depression and anxiety. The majority of patients showed reliable improvement/clinically significant change: intent-to-treat: 78.8%/57.3%; completer: 84.5%/65.1%. Dropouts and unreliable attenders had worse outcome. Statistically reliable symptom exacerbation with treatment was observed in only 1.2% of patients. Treatment gains were maintained during follow-up (M = 280 days, n = 220). Few of the selection criteria used in some RCTs, demographic, diagnostic and trauma characteristics moderated treatment outcome, and only social problems and needing treatment for multiple traumas showed unique moderation effects. There were no random effects of therapist on symptom improvement, but therapists who were inexperienced in CT-PTSD had more dropouts than those with greater experience.

Conclusions

The results support the effectiveness of CT-PTSD and suggest that trauma-focused cognitive behavior therapy can be successfully implemented in routine clinical services treating patients with a wide range of traumas.

•

Cognitive Therapy for PTSD can be effectively implemented in routine clinical care.

•

The intent-to-treat analysis showed very large treatment effects.

•

Patients found the treatment acceptable, and the majority showed clinically significant change.

•

Few patient characteristics moderated treatment outcome.

•

Inexperienced therapists had more dropouts.

The role of the therapeutic relationship in cognitive behaviour therapy for chronic fatigue syndrome

Cognitive behaviour therapy (CBT) for chronic fatigue syndrome (CFS) can reduce fatigue and impairment. Recently, it was found that changes in fatigue-perpetuating factors, i.e. focusing on symptoms, control over fatigue, perceived activity and physical functioning, are associated with and explain up to half of the variance in fatigue during CBT for CFS. The therapy relationship, e.g. outcome expectations and working alliance, may also contribute to treatment outcome. We aimed to examine the role of the therapy relationship in CBT and determine whether it exerts its effect independently of changes in fatigue-perpetuating factors. We used a cohort of 217 CFS patients in which the pattern of change in fatigue-perpetuating factors was examined previously. Fatigue, therapy relationship and fatigue-perpetuating factors were measured at the start of therapy, three times during CBT and at the end of therapy. Baseline outcome expectations and agreement about the content of therapy predicted post therapy fatigue. A large part of the variance in post-treatment fatigue (25%) was jointly explained by outcome expectations, working alliance and changes in fatigue-perpetuating factors. From this, we conclude that positive outcome expectations and task agreement seem to facilitate changes in fatigue-perpetuating factors during CBT for CFS. It is therefore important to establish a positive therapy relationship early in therapy.

Implementing evidence-based practice for patients with chronic fatigue syndrome

The aim of our study was to explore whether community-based mental health care centres (MHCs) are able to implement and sustain cognitive behaviour therapy (CBT) for chronic fatigue syndrome (CFS) with the help of an implementation manual. We monitored the implementation process and treatment outcome data of three Dutch MHCs that implemented or sustained CBT for CFS, one in the context of a stepped care programme. We compared these data with findings of other treatment studies conducted in the context of CBT for CFS. All three MHCs included at least 40 patients with dropout rates between 15% and 35% from intention-to-treat to second assessment. Effect sizes ranged between 0.88 and 1.76 for changes in fatigue severity and 0.43 and 1.23 for changes in physical functioning. With one exception, these outcomes were within the range of our benchmark. Contrary to original expectations, we provided additional implementation support to the two MHCs new with CBT for CFS. We concluded that our implementation manual does not seem to substitute external support for team leaders and associated professions during initial implementation of CBT for CFS but may have the potential to make this assistance more efficient. Particular attention should be paid to challenges of implementing stepped care for CFS.

KEY PRACTITIONERS MESSAGE

Implementation of CBT for CFS in community-based MHCs was monitored. External support was provided in addition to an implementation manual during initial implementation of CBT for CFS. Participating MHCs were generally capable of successfully implementing and delivering CBT for CFS. Implementation of low-intensity interventions for CFS might better be postponed until therapists have sufficient experience with conventional CBT for CFS.

Therapist effects and the dissemination of cognitive behavior therapy for chronic fatigue syndrome in community-based mental health care

OBJECTIVE

The purpose of the present study was to explore the role of the therapist in the dissemination of manualized cognitive behavior therapy (CBT) for chronic fatigue syndrome (CFS) outside specialized treatment settings.

METHOD

We used the routinely collected outcome data of three community-based mental health care centers (MHCs) which implemented and sustained CBT for CFS during the course of the study. Ten therapists, who all received the same training in CBT for CFS, and 103 patients with CFS were included.

RESULTS

Random effects modeling revealed a significant difference in mean post-treatment fatigue between therapists. The effect of the therapist accounted for 21% of the total variance in post-treatment fatigue in our sample. This effect could be explained by the therapists' attitude toward working with evidence-based treatment manuals as well as by the MHC where CBT for CFS was delivered.

CONCLUSION

The context in which CBT for CFS is delivered may play an important role in the accomplishment of established therapy effects outside specialized treatment settings. Due to the small sample size of MHCs and the different implementation scenarios in which they were engaged, our findings should be interpreted as preliminary results which are in need for replication.

Mindfulness-based cognitive therapy for people with chronic fatigue syndrome still experiencing excessive fatigue after cognitive behaviour therapy: a pilot randomized study

Cognitive behaviour therapy (CBT) is an effective treatment for chronic fatigue syndrome (CFS; sometimes known as myalgic encephalomyelitis). However, only a minority of patients fully recover after CBT; thus, methods for improving treatment outcomes are required. This pilot study concerned a mindfulness-based cognitive therapy (MBCT) intervention adapted for people with CFS who were still experiencing excessive fatigue after CBT. The study aimed to investigate the acceptability of this new intervention and the feasibility of conducting a larger-scale randomized trial in the future. Preliminary efficacy analyses were also undertaken. Participants were randomly allocated to MBCT or waiting list. Sixteen MBCT participants and 19 waiting-list participants completed the study, with the intervention being delivered in two separate groups. Acceptability, engagement and participant-rated helpfulness of the intervention were high. Analysis of covariance controlling for pre-treatment scores indicated that, at post-treatment, MBCT participants reported lower levels of fatigue (the primary clinical outcome) than the waiting-list group. Similarly, there were significant group differences in fatigue at 2-month follow-up, and when the MBCT group was followed up to 6 months post-treatment, these improvements were maintained. The MBCT group also had superior outcomes on measures of impairment, depressed mood, catastrophic thinking about fatigue, all-or-nothing behavioural responses, unhelpful beliefs about emotions, mindfulness and self-compassion. In conclusion, MBCT is a promising and acceptable additional intervention for people still experiencing excessive fatigue after CBT for CFS, which should be investigated in a larger randomized controlled trial.

KEY PRACTITIONER MESSAGE

Only about 30% of people with chronic fatigue syndrome (CFS) recover after cognitive behaviour therapy (CBT); thus, methods for improving treatment outcomes are needed. This is the first pilot randomized study to demonstrate that a mindfulness-based intervention was associated with reduced fatigue and other benefits for people with CFS who were still experiencing excessive fatigue after a course of CBT. Levels of acceptability, engagement in the intervention and rated helpfulness were high. A larger-scale randomized controlled trial is required.

Cognitive behaviour therapy for chronic fatigue syndrome in adults: face to face versus telephone treatment: a randomized controlled trial

BACKGROUND

Previous research has shown that face to face cognitive behaviour therapy (CBT) is an effective treatment for chronic fatigue syndrome (CFS)/Myalgic Encephalomyelitis (ME). However, some patients are unable to travel to the hospital for a number of reasons.

AIMS

The aim of this study was to assess whether face to face CBT was more effective than telephone CBT (with face to face assessment and discharge appointment) for patients with CFS.

METHOD

Patients aged 18-65 were recruited from consecutive referrals to the Chronic Fatigue Syndrome (CFS) Research and Treatment Unit at The South London and Maudsley NHS Trust in London. Participants were randomly allocated to either face to face CBT or telephone CBT by a departmental administrator. Blinding of participants and care givers was inappropriate for this trial. A parallel-groups randomised controlled trial was used to compare the two treatments. The primary outcomes were physical functioning and fatigue.

RESULTS

Significant improvements in the primary outcomes of physical functioning and fatigue occurred and were maintained to one year follow-up after discharge from treatment. Improvements in social adjustment and global outcome were noted and patient satisfaction was similar in both groups.

CONCLUSIONS

Results from this study indicate that telephone CBT with two face to face appointments is a mild to moderately effective treatment for CFS and may be offered to patients where face to face treatment is not a viable option. Despite these encouraging conclusions, dropout was relatively high and therapists should be aware of this potential problem.
