Implementation of stepped care for patients with chronic fatigue syndrome in community-based mental health care: outcomes at post-treatment and long-term follow-up.

BACKGROUND: Cognitive behavioural therapy (CBT) is an evidence-based treatment for chronic fatigue syndrome (CFS). Stepped care for CFS, consisting of a minimal intervention followed by face-to-face CBT, was found efficacious when tested in a CFS specialist centre. Stepped care implemented in a community-based mental health centre (MHC) has not yet been evaluated. AIMS: (1) To test the effectiveness of stepped care for CFS implemented in a MHC at post-treatment and at long-term follow-up; and (2) compare post-treatment outcomes of implemented stepped care with treatment outcomes of a CFS specialist centre. METHOD: An uncontrolled study was used to test effectiveness of stepped care implemented in a MHC (n = 123). The outcomes of implemented care were compared with the outcomes of specialist care reported in previous studies (n = 583). Data on outcomes from implemented stepped care were gathered at post-treatment and at long-term follow-up. Mixed models were used as method of analysis. RESULTS: Fatigue decreased and physical functioning increased significantly following implemented stepped care (both p < .001). The follow-up was completed by 94 patients (78%) within 1-6 years after treatment. Treatment effects were sustained to follow-up. Patients in the MHC showed less improvement directly following stepped care compared with patients in a CFS specialist centre (p < .01). CONCLUSION: Implemented stepped care for CFS is effective with sustained treatment gains at long-term follow-up. There is room for improvement when compared with outcomes of a CFS specialist centre. Some suggestions are made on how to improve stepped care.

[Utilisation of Psychotherapeutic Assistance By Diabetes Patients with a History of Migration]. / Die Inanspruchnahme psychotherapeutischer Leistungen durch Diabetes Patienten mit Migrationshintergrund.

According to available studies, migrant patients are more often affected by diabetes mellitus and comorbid psychological complaints than patients without a history of migration. Less is known about whether these patients receive psychotherapeutic assistance for their complaints and which factors may influence the utilisation of psychotherapy in this patient group. We sought to answer these questions by using culture sensitive material which included a screening for depressive symptoms (the Patient Health Questionnaire) and sociodemographic items. The material was completed once by patients of 2 collaborating family practices in the Düsseldorf Metropolitan Area during the total research period of 12 months. Both practices were participating in the Disease Management Programme (DMP) for diabetes mellitus (type 2). 42% of the 90 included patients had a clinically relevant depressive symptomatology. One third of these patients were in psychotherapy. One of the major barriers for the utilisation of psychotherapeutic help independent of the severity of depressive complaints was the existence of language barriers on the part of the patient. Patients with language barriers were about 10 times less likely to be in psychotherapy. Neither the duration that patients were living in Germany, nor the cultural match with the family practitioner, age or gender of patients played a significant role. The existence of death or suicidal fantasies, on the contrary, significantly increased the likelihood of being in psychotherapy. Implications of these data are discussed together with suggestions for future research.

Long-term follow-up after cognitive behaviour therapy for chronic fatigue syndrome.

OBJECTIVE: Cognitive behaviour therapy (CBT) is an effective treatment for chronic fatigue syndrome (CFS). Main aim was to determine whether treatment effects were maintained up to 10years after treatment. METHODS: Participants (n=583) of previously published studies on the effects of CBT for CFS were contacted for a long-term follow-up assessment. They completed questionnaires on main outcomes fatigue severity (CIS) and physical functioning (SF-36). The course of these outcomes since post-treatment assessment was examined using mixed model analyses. RESULTS: Between 21 and 125months after finishing CBT, 511 persons (response rate 88%) completed a follow-up assessment. At follow-up, mean fatigue severity was significantly increased to 37.60 (SD=12.76) and mean physical functioning significantly decreased to 73.16 (SD=23.56) compared to post-treatment assessment. At follow-up still 37% of the participants had fatigue scores in the normal range and 70% were not impaired in physical functioning. CONCLUSION: Positive effects of CBT for CFS on fatigue and physical functioning were partly sustained at long-term follow-up. However, a subgroup of patients once again reported severe fatigue, and compromised physical functioning. Further research should elucidate the reasons for this deterioration to facilitate the development of treatment strategies for relapse prevention.

Does migration affect the outcome of inpatient psychotherapy? Results from a retrospective cohort study.

OBJECTIVE: Reliable data to determine whether migrant patients benefit sufficiently from evidence-based mental health interventions are scarce. Our aim was to examine the effect of migration on the outcome of inpatient psychotherapy. METHODS: We conducted a retrospective cohort study and predicted the course of the global severity index of the Symptom Checklist 90 during therapy based on data from our routine clinical practice (N=542). We used mixed models for our analysis and included relevant clinical characteristics. RESULTS: One hundred and twenty-one patients of our sample had a history of migration which was consistently associated with more symptoms at baseline assessment. Patients with direct experiences of migration had the highest level of symptoms before therapy but also showed the largest decrease of symptoms during therapy (B=-0.09, SD=0.04, p=0.030). This interaction effect could be accounted for by our clinical variables. Patients with indirect experiences of migration did not differ from other patients in their level of improvement (B=-0.05, SD=0.04, p=0.149). CONCLUSION: According to our preliminary data, migration does not seem to negatively affect the outcome of inpatient psychotherapy. Limitations of these promising findings are discussed together with the strong need for more advanced studies in this area of research.

Course and Predictors of Postdeployment Fatigue: A Prospective Cohort Study in the Dutch Armed Forces.

OBJECTIVE: The purpose of this study was to examine course and predictors of fatigue in military personnel deployed to Afghanistan. METHODS: A total of 906 soldiers in the Dutch Armed Forces who participated in a 4-month mission to Afghanistan were included in this study. Assessment took place prior to and 1, 6, 12, and 24 months after deployment. Data were collected between 2005 and 2011. The fatigue severity subscale of the Checklist Individual Strength was used to indicate the level of fatigue during the previous 2 weeks. Mixed models and logistic regression analysis were used to predict course and prevalence of fatigue after deployment. Predictors of postdeployment fatigue were assessed prior to deployment. RESULTS: The mean level of fatigue increased significantly following deployment (B = 0.58, P = .007). In total, 274 soldiers (30.2%) were severely fatigued at least once after deployment and 130 (14.3%) soldiers had recurrent levels of severe fatigue. Only a minority of the veterans with severe fatigue could be classified as having posttraumatic stress disorder (PTSD, per DSM-IV-TR criteria) or potential medical problems. Significant predeployment predictors of less favorable courses of fatigue after deployment were higher levels of fatigue (B = 0.46, P ≤ .001), emotional abuse during childhood (B = 0.99, P ≤ .001), and harm avoidance (B = 0.27, P = .012). These predeployment factors also predicted severe fatigue after deployment. CONCLUSIONS: Severe fatigue is a substantial problem in Afghanistan War veterans that does not seem to resolve over time. In a majority of cases, the symptoms cannot be attributed to medical problems or PTSD, whereas predeployment differences in psychosocial factors partially explain course and prevalence of postdeployment fatigue. These findings support assumptions that a complex interplay of various factors might be responsible for the symptoms.

Randomised controlled trial of cognitive behaviour therapy delivered in groups of patients with chronic fatigue syndrome.

BACKGROUND: Meta-analyses have been inconclusive about the efficacy of cognitive behaviour therapies (CBTs) delivered in groups of patients with chronic fatigue syndrome (CFS) due to a lack of adequate studies. METHODS: We conducted a pragmatic randomised controlled trial with 204 adult CFS patients from our routine clinical practice who were willing to receive group therapy. Patients were equally allocated to therapy groups of 8 patients and 2 therapists, 4 patients and 1 therapist or a waiting list control condition. Primary analysis was based on the intention-to-treat principle and compared the intervention group (n = 136) with the waiting list condition (n = 68). The study was open label. RESULTS: Thirty-four (17%) patients were lost to follow-up during the course of the trial. Missing data were imputed using mean proportions of improvement based on the outcome scores of similar patients with a second assessment. Large and significant improvement in favour of the intervention group was found on fatigue severity (effect size = 1.1) and overall impairment (effect size = 0.9) at the second assessment. Physical functioning and psychological distress improved moderately (effect size = 0.5). Treatment effects remained significant in sensitivity and per-protocol analyses. Subgroup analysis revealed that the effects of the intervention also remained significant when both group sizes (i.e. 4 and 8 patients) were compared separately with the waiting list condition. CONCLUSIONS: CBT can be effectively delivered in groups of CFS patients. Group size does not seem to affect the general efficacy of the intervention which is of importance for settings in which large treatment groups are not feasible due to limited referral.

Illness perceptions in patients with somatoform disorders: examining the role of comorbidity.

We examined the role of comorbidity in models that use the illness perceptions of patients with somatoform disorders to explain their outcomes. A total of 138 primary care patients with somatoform disorders completed the Patient Health Questionnaire and Brief Illness Perception Questionnaire and rated their general health status. Medical comorbidity was rated by the general practitioner. Patients' illness perceptions were consistently related to their outcomes independent of medical and psychological comorbidity in our models. At the same time, inclusion of comorbidity enhanced our models, revealing differences in the relevance of the specific comorbidity depending on the outcome measure.

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.

Suicidality in primary care patients with somatoform disorders.

OBJECTIVE: To examine rates of suicidality in primary care patients with somatoform disorders and to identify factors that might help to understand and manage active suicidal ideation in these patients. METHODS: We conducted a cross-sectional study screening 1645 primary care patients. In total, 142 patients fulfilled the criteria for a somatoform disorder. Suicidality and illness perceptions were assessed in these patients. RESULTS: Of the 142 patients, 23.9% had active suicidal ideation during the previous 6 months; 17.6% had attempted to commit suicide in the past, the majority after onset of the somatoform symptoms. We tested two models with suicidal ideation as a dependent variable. In the first model, comorbid symptoms of depression (odds ratio [OR] = 1.17, 95% confidence interval [CI] = 1.03-1.33) and previous suicide attempts (OR= 3.02, 95% CI = 1.06-8.62) were significantly associated with suicidal ideation. Comorbid symptoms of anxiety did not yield significance. Illness perceptions and age of onset of the symptoms were then added to this model to test the role of somatoform-specific factors in addition to previous factors. In the complete model, comorbid symptoms of depression (OR = 1.15, 95% CI = 1.00-1.32) and dysfunctional illness perceptions (OR = 1.06, 95% CI = 1.01-1.11) were independently associated with active suicidal ideation, whereas the other factors did not yield significance. CONCLUSIONS: According to our data, suicidality seems to be a substantial problem in primary care patients with somatoform disorders. Dysfunctional illness perceptions may play a vital role in the understanding and management of active suicidal ideation in these patients, in addition to more established factors.

Suicidal ideation in German primary care.

OBJECTIVE: To examine suicidal ideation in a sample of German primary care patients. METHODS: We conducted a cross-sectional study and included 1455 primary care patients who visited 1 of 41 general practitioners (GPs) working at 19 different sites. Suicidal ideation and psychopathology were assessed with the Patient Health Questionnaire (PHQ) in an anonymous screening together with health care utilization. RESULTS: One hundred seventy-one (11.8%) of 1455 patients endorsed the suicidal ideation item of the PHQ. These patients were significantly younger, more often female and unmarried, suffered more often from psychopathology and reported more health care utilization than patients without suicidal ideation. Patients with the highest frequency of suicidal ideation also talked more often routinely about psychosocial problems with their GP, used more often medication against their complaints and searched more often for a psychotherapist than other suicidal ideators. Yet, these patients were not more likely to be in psychotherapy at the time of the screening. CONCLUSION: Our data suggest that suicidal ideation is a common phenomenon in primary care, which is independently associated with psychopathology in terms of depression, anxiety and somatoform complaints. Psychosocial support from GPs and medication seem to be easier available for primary care patients with suicidal ideation than psychotherapy, independent of the severity of the suicidal ideation.

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.

Towards an evidence-based treatment model for cognitive behavioral interventions focusing on chronic fatigue syndrome.

OBJECTIVE: The purpose of the present study was to develop a treatment model for cognitive behavioral interventions focusing on chronic fatigue syndrome (CFS) based on the model of perpetuating factors introduced by Vercoulen et al. [Journal of Psychosomatic Research 1998;45:507-17]. METHODS: For this purpose, we reanalyzed the data of a previously conducted randomized controlled trial in which a low intensity cognitive behavioral intervention was compared to a waiting list control group. Structural equation modeling was used to test a treatment model in which changes in focusing on symptoms, perceived problems with activity, and sense of control over fatigue were hypothesized to mediate the effect of our intervention on fatigue severity and disability. RESULTS: In the final model, which had a good fit to the data, the effect of treatment was mediated by a decrease in perceived problems with activity and an increase in sense of control over fatigue. CONCLUSION: Our findings suggest that cognitive behavioral interventions for CFS need to change the illness perception and beliefs of their patients in order to be effective.

Examining the role of physical activity in reducing postcancer fatigue.

PURPOSE: Persistent fatigue is a long-term adverse effect experienced in about a quarter of patients cured of cancer. It was shown that cognitive behavior therapy (CBT) especially designed for postcancer fatigue is highly effective in reducing severe fatigue. However, it is unclear by what mechanism the fatigue reduction is reached. In many fatigue reduction programs, an increase in physical activity is assumed to reduce fatigue. The purpose of the present study is to determine whether the effect of CBT on fatigue is mediated by an increase in physical activity. METHODS: Data of a previous randomized controlled trial on the efficacy of CBT for postcancer fatigue were reanalyzed (CBT, n = 41; waiting list condition, n = 42). Actigraphy was used to assess the level of objective physical activity. Cancer survivors were assessed prior as well as after the CBT and waiting list period. The mediation hypothesis was tested according to guidelines of Baron and Kenny. A non-parametric bootstrap approach was used to test statistical significance of the mediation effect. RESULTS: Although CBT effectively reduced postcancer fatigue, no change in level of objective physical activity was found. The mean mediation effect was 1.4% of the total treatment effect. This effect was not significant. CONCLUSION: The effect of CBT for postcancer fatigue is not mediated by a persistent increase in objective physical activity.

Does a decrease in avoidance behavior and focusing on fatigue mediate the effect of cognitive behavior therapy for chronic fatigue syndrome?

OBJECTIVE: Cognitive behavior therapy (CBT) leads to a significant reduction in fatigue severity and impairment in patients with chronic fatigue syndrome (CFS). The purpose of the present study was to determine whether the effect of CBT for CFS on fatigue and impairment is mediated by a decrease in avoidance behavior and focusing on fatigue. METHODS: For this purpose, we reanalyzed a randomized controlled trial which was previously conducted to test the efficacy of CBT for CFS. Two hundred nineteen patients completed assessment prior and subsequent to treatment or a control group period. RESULTS: Mediation analysis revealed that a decrease in focusing on fatigue mediated the effect of CBT for CFS on fatigue and impairment. Avoidance of activity and avoidance of aversive stimuli were not significantly changed by treatment and were therefore excluded from mediation analysis. CONCLUSION: A decrease in the focus on fatigue seems to contribute to the treatment effect of CBT for CFS.

Being homebound with chronic fatigue syndrome: A multidimensional comparison with outpatients.

Many patients with chronic fatigue syndrome (CFS) seem to experience periods in which they are homebound due to their symptomatology. Despite a growing body of research about CFS, little is known about patients who no longer feel able to leave their homes. The purpose of the present study was to examine whether homebound patients differ from other CFS patients on illness-specific characteristics. Besides experiencing more impairment in daily functioning than participants of an outpatient intervention study, homebound patients were characterised by extremely high levels of daily fatigue, predominant somatic attributions, and pervasively passive activity patterns. The course of symptomatology was similarly stable in both groups. Our findings suggest that homebound patients form a distinct subgroup of CFS patients who might profit from a treatment approach that is tailored to their specific needs. The exploratory nature of this first systematic investigation of homebound CFS patients is stressed, and suggestions for future research are made.
