Self-Critical Perfectionism, Stress Generation, and Stress Sensitivity in Patients with Chronic Fatigue Syndrome: Relationship with Severity of Depression

Chronic Fatigue Syndrome (CFS) is a highly disabling disorder that is part of a broader spectrum of chronic pain and fatigue disorders. Although the etiology and pathogenesis of CFS largely remain unclear, there is increasing evidence that CFS shares important pathophysiological disturbances with mood disorders in terms of disturbances in the stress response and the stress system. From a psycho-dynamic perspective, self-critical perfectionism and related personality factors are hypothesized to explain in part impairments of the stress response in both depression and CFS. Yet, although there is ample evidence that high levels of self-critical perfectionism are associated with stress generation and increased stress sensitivity in depression, evidence supporting this hypothesis in CFS is currently lacking. This study therefore set out to investigate the relationship between self-critical perfectionism, the active generation of stress, stress sensitivity, and levels of depression in a sample of 57 patients diagnosed with CFS using an ecological momentary assessment approach. Results showed, congruent with theoretical assumptions, that self-critical perfectionism was associated with the generation of daily hassles, which in turn predicted higher levels of depression. Moreover, multilevel analyses showed that self-critical perfectionism was related to increased stress sensitivity in CFS patients over a 14-day period, and that increased stress sensitivity in turn was related to increased levels of depression. The implications of these findings for future research and particularly for the development of psychodynamic treatment approaches of CFS and related conditions are discussed.

Psychiatric Aspects of Chronic Fatigue Syndrome and Fibromyalgia

Chronic fatigue syndrome and/or fibromyalgia (CFS/FM) consists of highly overlapping, medically unexplained symptoms, including long-lasting fatigue, effort intolerance, cognitive dysfunction, and widespread pain and tenderness. CFS/FM often seems to be triggered by infections and physical trauma, but depression, sleep disturbances, and personality may also be involved. Moreover, dysregulation of the stress system, the immune system, and central pain mechanisms may determine the pathophysiology of the illness, leading to a loss of capacity to adapt to all kind of stressors. CFS/FM patients can be best helped by a pragmatic and individualized approach aimed at adjusting lifestyle and optimizing self-care, which in the long run may contribute to a restoration of physical and mental adaptability. Future psychiatric research into CFS/FM should focus on the complex interrelationships among pain/fatigue, stress/depression, and personality, as well as on processes of therapeutic change and the advantages of customized treatment.

Unraveling the role of perfectionism in chronic fatigue syndrome: Is there a distinction between adaptive and maladaptive perfectionism?

In the current study, we investigated whether the distinction between adaptive (i.e. high personal standards) and maladaptive (i.e. concern over mistakes and doubt about actions) perfectionism that has been found in the literature, is also valid in patients with chronic fatigue syndrome (CFS). We hypothesized that maladaptive, but not adaptive, perfectionism would be significantly and positively related to severity of fatigue and depression in CFS. We examined this hypothesis in a sample of 192 CFS patients using structural equation modelling (SEM). Although the two perfectionism dimensions were related to each other, results supported a model in which only maladaptive perfectionism was positively related to severity of fatigue and depression. Further, we found that depression fully mediated the effect of maladaptive perfectionism on fatigue. The results suggest that adaptive and maladaptive perfectionism are two distinct, albeit related, dimensions in CFS. Findings of this study have important implications for theory and treatment of CFS, particularly for cognitive-behavioral treatment.

Predictors of outcome in a multi-component treatment program for chronic fatigue syndrome

BACKGROUND Little is known about factors predicting treatment outcome in chronic fatigue syndrome (CFS). METHODS Based on Vercoulen et al.s (1998) cognitive-behavioral model of perpetuating factors in CFS, the predictive value of the following patient characteristics were examined in a sample of 178 CFS patients who followed a multi-component treatment program: (1) somatic attributions, (2) psychological attributions, (3) sense of control over symptoms, (4) physical activity, (5) functional impairment, (6) somatic focus, and (7) severity of depression. RESULTS Only pre-treatment severity of depression was associated with negative treatment outcome defined in terms of post-treatment fatigue and improvement in fatigue. LIMITATIONS The study was conducted at a tertiary care centre and did not include a control group or a long-term follow-up. CONCLUSIONS Level of depression may be the most important factor of the cognitive-behavioral model predicting post-treatment fatigue in CFS. Hence, findings suggest that treatment of CFS should include a focus on severity of depression.

Psychodynamic and cognitive-behavioral approaches of obsessive-compulsive disorder: Is it time to work through our ambivalence?

This paper provides an overview of the growing convergence among psychodynamic and cognitive-behavioral approaches of Obsessive-Compulsive Disorder (OCD). From a traditional psychoanalytic point of view, OCD is mainly conceptualized in terms of a constant conflict between feelings of love and hate. More recent psychodynamic theories of OCD, such as the object-relational model, focus on the role of ambivalent mental representations or cognitive-affective schemas of self and others. This notion of mental representations or schemas links psychodynamic formulations to cognitive-behavioral approaches of OCD. Moreover, there is increasing overlap between psychodynamic and cognitive-behavioral models concerning the core dynamics involved in OCD. Implications of this convergence for future research and clinical practice are discussed.

The prevalence and impact of early childhood trauma in Chronic Fatigue Syndrome

BACKGROUND Although some studies have found high rates of early childhood trauma in Chronic Fatigue Syndrome (CFS), the role of early trauma in this condition remains controversial. METHODS This study examined the prevalence of early childhood trauma and its impact on daily fatigue and pain levels over a 14-day period in a sample of 90 carefully screened CFS patients using a diary method approach. Data were analyzed using multilevel analysis. RESULTS More than half of the patients (54.4%) had experienced at least one type of early trauma, with the majority of these patients reporting multiple traumas. Prevalence rates were particularly high for emotional trauma (i.e., emotional abuse and/or emotional neglect) (46.7%). Moreover, total trauma scores and emotional abuse significantly predicted higher levels of daily fatigue and pain over the 14-day period, even when controlling for demographic features and depressed mood. CONCLUSIONS This is the first study to demonstrate that early childhood trauma predicts increasing levels of core symptoms of CFS in the daily flow of life. Moreover, findings of this study suggest that emotional trauma may be particularly important in CFS.

Self-critical perfectionism and its relationship to fatigue and pain in the daily flow of life in patients with chronic fatigue syndrome.

BACKGROUND Research suggests that the personality factor of self-critical or maladaptive perfectionism may be implicated in chronic fatigue syndrome (CFS). However, it is not clear whether self-critical perfectionism (SCP) also predicts daily symptoms in CFS. Method In the present study we investigated whether SCP predicted fatigue and pain over a 14-day period in a sample of 90 CFS patients using a diary method approach. After completing the Depressive Experiences Questionnaire (DEQ) as a measure of SCP, patients were asked each day for 14 days to complete Visual Analogue Scales (VAS) of fatigue, pain and severity of depression. Data were analysed using multilevel analysis. RESULTS The results from unconditional models revealed considerable fluctuations in fatigue over the 14 days, suggesting strong temporal variability in fatigue. By contrast, pain was relatively stable over time but showed significant inter-individual differences. Congruent with expectations, fixed-effect models showed that SCP was prospectively associated with higher daily fatigue and pain levels over the 14-day period, even after controlling for levels of depression. CONCLUSIONS This is the first study to show that SCP predicts both fatigue and pain symptoms in CFS in the daily course of life. Hence, therapeutic interventions aimed at targeting SCP should be considered in the treatment of CFS patients with such features.

Stability and Change in Levels of Depression and Personality: A Follow-up Study of Postpartum Depressed Mothers That Were Hospitalized in a Mother-Infant Unit

This prospective longitudinal study investigated the role of the personality dimensions of dependency and self-criticism in the course of depressive symptoms in a sample of inpatient severely postpartum depressed mothers (n = 55). Depressive symptoms and personality were measured during hospitalization and on average 3 1/2 years later. In line with previous research, a considerable subgroup of mothers (39%) reported moderate to severe symptoms of depression at time 2. In addition, although these mothers did not exhibit more depressive episodes during follow-up period compared with mothers with a less chronic course of depression, their depressive episodes were considerably longer, and they had higher levels of severity of depression as well as of dependency and self-criticism at Time 1. Finally, self-criticism, but not dependency, assessed at Time 1, predicted both depression diagnosis and levels of depression at follow-up, supporting a vulnerability model positing that self-criticism confers vulnerability for depression over time.

Multidisciplinary pain education program (MPEP) for chronic pain patients: preliminary evidence for effectiveness and mechanisms of change

Abstract Objective: There is a need for effective brief interventions in chronic pain patients, and the identification of mechanisms of change. Method: In the present study, we tested the effectiveness of MPEP (Multidisciplinary Pain Education Program), a very brief, four-session cognitive-behaviorally based psycho-educational intervention for chronic pain using a pre-and post-test design. In addition, pre- to post-treatment change scores were calculated to investigate factors associated with change in pain. Participants of the study were 53 patients with chronic non-cancer pain. Primary outcome measures were (1) pain severity, (2) health perception, and (3) severity of depression. Secondary outcome measures included factors that have been implicated in the maintenance of chronic pain and that might be associated with worse treatment outcome: (1) catastrophizing, (2) kinesiophobia, and (3) action-proneness. Results: Findings provided preliminary evidence for the effectiveness of MPEP in that patients showed significant and clinically meaningful improvements in pain symptoms (F = 24.503, p < 0.001, d = 0.59) and action-proneness (F = 178.504, p < 0.001, d = 1.95), and small improvements in health perception (F = 7.116, p < 0.05, d = 0.30). Furthermore, results showed that changes in catastrophizing (β = −0.455, p = 0.001) and severity of depression (β = −0.300, p < 0.05) were independently and significantly associated with changes in pain. However, changes in health perception, kinesiophobia, and action-proneness were not significantly associated with changes in pain (β = 0.203, ns; β = 0.003, ns; and β = 0.154, ns, respectively). Importantly, duration of chronic pain was not related to treatment outcome (β = 0.070, ns). Conclusions: Overall, this study provides preliminary evidence for the effectiveness of MPEP and possible mechanisms through which MPEP is effective. Yet, further research is needed to investigate the efficacy of MPEP.

Effects of early childhood trauma on hypothalamic–pituitary–adrenal (HPA) axis function in patients with Chronic Fatigue Syndrome

BACKGROUND There is a paucity of studies that have investigated the assumption that early childhood trauma is associated with hypothalamic-pituitary-adrenal (HPA) axis dysfunction in Chronic Fatigue Syndrome (CFS). The current study is the first to simultaneously investigate relationships among early childhood trauma, cortisol activity, and cortisol stress reactivity to psychosocial stress in a sample of well-screened CFS patients. We also examined whether self-critical perfectionism (SCP) plays a mediating role in the potential relationship between early trauma and neurobiological stress responses. METHODS A total of 40 female patients diagnosed with CFS were asked to provide morning saliva cortisol samples (after awakening, 30min later, and 1h later) for seven consecutive days as a measure of cortisol activity. In addition, patients were exposed to the Trier Social Stress Test, a well-validated stress test, to investigate the relationship between early childhood trauma and cortisol stress reactivity. Before the start of the study, patients completed the Childhood Trauma Questionnaire-Short form (CTQ-SF) as a measure of early childhood trauma (i.e. sexual, physical and emotional traumatic experiences). SCP was measured with the Depressive Experiences Questionnaire (DEQ). Data were analyzed by calculating several indices of cortisol secretion (i.e. Cortisol Awakening Response and Area Under the Curve). RESULTS There was no association between early childhood trauma and cortisol as measured over the 7-day period. However, emotional neglect was significantly negatively related to cortisol reactivity in the TSST. SCP did not significantly mediate this association. CONCLUSION Findings of this study suggest that emotional neglect is associated with blunted HPA axis reactivity, congruent with the assumption that CFS may reflect loss of adaptability of the neuroendocrine stress response system in at least a subgroup of patients.
