Personality and social attitudes in chronic fatigue syndrome

Perfectionism, depression and anxiety in chronic fatigue syndrome: A systematic review

OBJECTIVE

High levels of depression and anxiety are experienced alongside Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME). Psychological causal and maintenance factors are not well-understood. Perfectionism is a multifactorial, transdiagnostic risk factor for various physical and mental health conditions. This systematic review assesses the association between perfectionism and depression and/or anxiety in people with CFS/ME.

METHOD

Systematic literature searches used a combination of terms for 'perfectionism', 'depression', 'anxiety' and 'CFS/ME'. Peer-reviewed English-language papers reporting quantitative data regarding the relationship between perfectionism and depression and/or anxiety in adults (aged 18-65 years) with a clinical diagnosis of CFS/ME were included. Screening, selection and assessment of risk of bias was completed independently by two authors. Bivariate and multivariate associations between perfectionism and anxiety and depression were extracted. Data were synthesised narratively.

RESULTS

Seven studies, reported in eight papers, were included. Seven examined the relationship between perfectionism and depression. Moderate-strong significant positive associations were found between depression and maladaptive perfectionism (r = 0.42 to .48, p < .01), and its component factors of concern over mistakes (r = 0.40 to .60, p < .01) and doubts about actions (r = 0.51 to .60, p < .01). Methodological limitations included sample size justification and selection, psychometric measures, and control of potential confounders.

CONCLUSION

Maladaptive perfectionism is consistently associated with depression in patients with CFS/ME. The relationship between perfectionism and anxiety is under-researched. Corroboration is required from longitudinal, cross-cultural studies. Clinical understanding may be increased through examining the interplay between maladaptive perfectionism, depression and anxiety and the physical and cognitive symptoms of CFS/ME.

The 'cognitive behavioural model' of chronic fatigue syndrome: Critique of a flawed model

Chronic fatigue syndrome/myalgic encephalomyelitis is a debilitating illness that greatly impacts the lives of sufferers. A cognitive behavioural model attempts to explain illness onset and continuance with a hypothesis that the illness is perpetuated by patients' irrational beliefs and avoidance behaviours. This theory underpins the promotion of cognitive behavioural therapy, a treatment that aims to change beliefs and behaviours. This article reports on a detailed review of the cognitive behavioural model. Our review finds that the model lacks high-quality evidential support, conflicts with accounts given by most patients and fails to account for accumulating biological evidence of pathological and physiological abnormalities found in patients. There is little scientific credibility in the claim that psycho-behavioural therapies are a primary treatment for this illness.

Myalgic encephalomyelitis/chronic fatigue syndrome and the biopsychosocial model: a review of patient harm and distress in the medical encounter

Objective: Despite the growing evidence of physiological and cellular abnormalities in myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS), there has been a strong impetus to tackle the illness utilizing a biopsychosocial model. However, many sufferers of this disabling condition report distress and dissatisfaction following medical encounters. This review seeks to account for this discord.Methods: A narrative review methodology is employed to synthesize the evidence for potential iatrogenesis.Results: We identify seven potential modalities of iatrogenesis or harm reported by patients:difficulties in reaching an acceptable diagnosis;misdiagnosis, including of other medical and psychological conditions;difficulties in accessing the sick role, medical care and social support;high levels of patient dissatisfaction with the quality of medical care;negative responses to controversial therapies (cognitive behavioral therapy and graded exercise therapy);challenges to the patient narrative and experience;psychological harm (individual and collective distress).Conclusion: The biopsychosocial framework currently applied to ME/CFS is too narrow in focus and fails to adequately incorporate the patient narrative. Misdiagnosis, conflict, and harm are observable outcomes where doctors' and patients' perspectives remain incongruent. Biopsychosocial practices should be scrutinized for potential harms. Clinicians should consider adopting alternative patient-centred approaches.Implications for rehabilitationPatients with ME/CFS may report or experience one or more of the modalities of harms and distress identified in this review.It is important health and rehabilitation professionals seek to avoid and minimize harms when treating or assisting ME/CFS patients.There are conflicting models of ME/CFS; we highlight two divergent models, a biopsychosocial model and a biomedical model that is preferred by patients.The 'biopsychosocial framework' applied in clinical practice promotes treatments such as cognitive behavioral therapy and exercise therapy, however, the evidence for their success is contested and many patients reject the notion their illness is perpetuated by dysfunctional beliefs, personality traits, or behaviors.Health professionals may avoid conflict and harm causation in ME/CFS by adopting more concordant 'patient-centred' approaches that give greater prominence to the patient narrative and experience of illness.

Deconstructing post-exertional malaise in myalgic encephalomyelitis/ chronic fatigue syndrome: A patient-centered, cross-sectional survey

BACKGROUND

Post-exertional malaise (PEM) is considered to be the hallmark characteristic of myalgic encephalomyelitis/ chronic fatigue syndrome (ME/CFS). Yet, patients have rarely been asked in formal studies to describe their experience of PEM.

OBJECTIVES

To describe symptoms associated with and the time course of PEM.

METHODS

One hundred and fifty subjects, diagnosed via the 1994 Fukuda CFS criteria, completed a survey concerning 11 symptoms they could experience after exposure to two different types of triggers. We also inquired about onset and duration of PEM and included space for subjects to write in any additional symptoms. Results were summarized with descriptive statistics; McNemar's, paired t-, Fisher's exact and chi-square goodness-of-fit tests were used to assess for statistical significance.

RESULTS

One hundred and twenty-nine subjects (90%) experienced PEM with both physical and cognitive exertion and emotional distress. Almost all were affected by exertion but 14 (10%) reported no effect with emotion. Fatigue was the most commonly exacerbated symptom but cognitive difficulties, sleep disturbances, headaches, muscle pain, and flu-like feelings were cited by over 30% of subjects. Sixty percent of subjects experienced at least one inflammatory/ immune-related symptom. Subjects also cited gastrointestinal, orthostatic, mood-related, neurologic and other symptoms. Exertion precipitated significantly more symptoms than emotional distress (7±2.8 vs. 5±3.3 symptoms (median, standard deviation), p<0.001). Onset and duration of PEM varied for most subjects. However, 11% reported a consistent post-trigger delay of at least 24 hours before onset and 84% endure PEM for 24 hours or more.

CONCLUSIONS

This study provides exact symptom and time patterns for PEM that is generated in the course of patients' lives. PEM involves exacerbation of multiple, atypical symptoms, is occasionally delayed, and persists for extended periods. Highlighting these characteristics may improve diagnosis of ME/CFS. Incorporating them into the design of future research will accelerate our understanding of ME/CFS.

Factors determining fatigue in the chronic fatigue syndrome: a path analysis

OBJECTIVES

To explore the interrelationship of different dimensions (fatigue, neuroticism, sleep quality, global mental and physical health) in patients with chronic fatigue syndrome (CFS).

METHODS

Patients meeting the Fukuda criteria of CFS filled out two independent fatigue scales (Fatigue Questionnaire, FQ and Checklist Individual Strength, CIS), NEO-Five Factor Inventory (NEO-FFI), Pittsburgh Sleep Quality Index (PSQI) and Medical Outcomes Study 36-item Short Form Health Survey (SF36). Exploratory and confirmatory path analyses were performed.

RESULTS

Out of 226 eligible patients, 167 subjects were included (mean age 39.13 years, SD 10.14, 92% female). In a first exploratory path analysis, using FQ for assessment of fatigue, night-time PSQI sleep quality had a direct effect on SF36 physical quality of life (PQoL) and no effect on FQ fatigue. This was confirmed by a subsequent path analysis with CIS fatigue and by confirmatory path analyses in 81 patients. These unexpected results raised the question whether FQ or CIS fatigue sufficiently operationalizes fatigue in CFS patients.

CONCLUSIONS

Poor sleep quality seems to directly impact on mental quality of life (MQoL) and PQoL without mediation of fatigue assessed with FQ and CIS. A more cohesive framework needs to be developed with more comprehensive clinical tools for the different dimensions in the construct of CFS.

Differences in alexithymia and emotional awareness in exhaustion syndrome and chronic fatigue syndrome

Symptoms of Exhaustion Syndrome (ES) and Chronic Fatigue Syndrome (CFS) are overlapping and create difficulties of differential diagnosis. Empirical studies comparing ES and CFS are scarce. This study aims to investigate if there are any emotional differences between ES and CFS. This cross-sectional study compared self-reported alexithymia and observer-rated emotional awareness in patients with ES (n = 31), CFS (n = 38) and healthy controls (HC) (n = 30). Self-reported alexithymia was measured with the Toronto Alexithymia Scale-20 (TAS-20) and emotional awareness with an observer-rated performance test, the Level of Emotional Awareness Scale (LEAS). Additionally, depression and anxiety were scored by the Hospital Anxiety and Depression Scale (HADS). Results show that patients with ES expressed higher self-reported alexithymia in the TAS-20 compared to HC, but had similar emotional awareness capacity in the observer-rated performance test, the LEAS. Patients with CFS expressed more difficulties in identifying emotions compared to HCs, and performed significantly worse in the LEAS-total and spent more time completing the LEAS as compared to HC. Correlation and multiple regressions analyses revealed that depression and anxiety positively correlated with and explained part of the variances in alexithymia scores, while age and group explained the major part of the variance in LEAS. Findings of this study indicate that emotional status is different in patients with ES and CFS with respect to both self-reported alexithymia and observer-rated emotional awareness. Emotional parameters should be approached both in clinical investigation and psychotherapy for patients with ES and CFS.

Accurate diagnosis of myalgic encephalomyelitis and chronic fatigue syndrome based upon objective test methods for characteristic symptoms

Although myalgic encephalomyelitis (ME) and chronic fatigue syndrome (CFS) are considered to be synonymous, the definitional criteria for ME and CFS define two distinct, partially overlapping, clinical entities. ME, whether defined by the original criteria or by the recently proposed criteria, is not equivalent to CFS, let alone a severe variant of incapacitating chronic fatigue. Distinctive features of ME are: muscle weakness and easy muscle fatigability, cognitive impairment, circulatory deficits, a marked variability of the symptoms in presence and severity, but above all, post-exertional “malaise”: a (delayed) prolonged aggravation of symptoms after a minor exertion. In contrast, CFS is primarily defined by (unexplained) chronic fatigue, which should be accompanied by four out of a list of 8 symptoms, e.g., headaches. Due to the subjective nature of several symptoms of ME and CFS, researchers and clinicians have questioned the physiological origin of these symptoms and qualified ME and CFS as functional somatic syndromes. However, various characteristic symptoms, e.g., post-exertional “malaise” and muscle weakness, can be assessed objectively using well-accepted methods, e.g., cardiopulmonary exercise tests and cognitive tests. The objective measures acquired by these methods should be used to accurately diagnose patients, to evaluate the severity and impact of the illness objectively and to assess the positive and negative effects of proposed therapies impartially.

The first step is the hardest - emotion recognition in patients with somatoform disorders

OBJECTIVES

The aetiology of somatoform disorders is assumed to consist of several factors, as alexithymia, dysfunctional cognitions and emotion regulation. As a consequence of somatoform disorders social withdrawal is discussed. Several studies prove connections between mental problems, emotion recognition, and functioning social relationships.

METHODS

A sample of 35 patients suffering from a somatoform disorder and a sample of 73 persons without any somatoform symptoms were investigated according to their ability to identify emotional facial expressions (computer-assisted presentation of photos).

RESULTS

Our results demonstrate significant differences in the ability to decode others' emotional states between people with or without somatoform disorders. In all six tests the patients achieved significantly worse results.

CONCLUSIONS

Our results suggest that psychotherapeutic treatment of patients with somatoform disorders should also focus on the recognition of emotions and deal with them.

Relationship between psychological factors and arthralgia in patients with rheumatoid arthritis

Abstract Various factors were assessed in terms of their contribution to arthralgia in a rheumatoid arthritis patient. Eighty-two outpatients (62 women and 20 men) with rheumatoid arthritis (RA) were examined with respect to the subjective degree of arthralgia, age, disease duration, dysfunction, steroid dose, steroid period, depression, anxiety, extroversion, neurotic disorder, and number of caretakers. The results were explained on the basis of stepwise regression analysis and psychological and clinical data. We analyzed results of a correlation coefficient test on the mutual relationship between variables. Stepwise regression analysis was performed to assess factors of arthralgia in terms of "depression," "mean activity," "morning stiffness," and "steroid dose." Depression is a factor of arthralgia as shown in this study, but it is clear that other factors are also involved. Anxiety was a factor distinct from the activity of RA. The factor contributing most to arthralgia was found to be depression, whereas anxiety had no effect.

The role of neuroticism, perfectionism and depression in chronic fatigue syndrome. A structural equation modeling approach

OBJECTIVE

Previous studies have reported consistent associations between Neuroticism, maladaptive perfectionism and depression with severity of fatigue in Chronic Fatigue Syndrome (CFS). Depression has been considered a mediator factor between maladaptive perfectionism and fatigue severity, but no studies have explored the role of neuroticism in a comparable theoretical framework. This study aims to examine for the first time, the role of neuroticism, maladaptive perfectionism and depression on the severity of CFS, analyzing several explanation models.

METHODS

A sample of 229 CFS patients were studied comparing four structural equation models, testing the role of mediation effect of depression severity in the association of Neuroticism and/or Maladaptive perfectionism on fatigue severity.

RESULTS

The model considering depression severity as mediator factor between Neuroticism and fatigue severity is the only one of the explored models where all the structural modeling indexes have fitted satisfactorily (Chi square=27.01, p=0.079; RMSE=0.047, CFI=0.994; SRMR=0.033). Neuroticism is associated with CFS by the mediation effect of depression severity. This personality variable constitutes a more consistent factor than maladaptive perfectionism in the conceptualization of CFS severity.

Personality and chronic fatigue syndrome: The role of the five-factor model

The aim of this study was to examine the relationships between personality factors and the symptomatology of fatigue among people with chronic fatigue syndrome (CFS), and compare them to people from the general population. Seventy-seven CFS patients (47 women, 30 men) were compared with 72 healthy individuals (44 women, 28 men) to investigate whether personality factors are related to the symptomatology of fatigue. All participants were asked to complete the NEO Five Factor Inventory (NEO-FFI), the Modified Fatigue Impact Scale (MFIS), the Fatigue Severity Scale (FSC), and the Mental Health Inventory (MHI). The results revealed that the CFS group reported higher levels of neuroticism and conscientiousness than the control group. These two personality factors were significantly related to fatigue symptoms, impact, and severity in both groups. These findings suggest that personality factors of neuroticism and conscientiousness may play an important role in the development and perpetuation of fatigue symptoms.

Interpersonal problems in alexithymia: A study in three primary care groups

OBJECTIVES

The present study investigated the relation between alexithymia and interpersonal problems in a sample of primary care patients with either chronic fatigue syndrome (CFS); a chronic cardiovascular or auto-immune disease; or a minor medical condition. It was hypothesized that the relation between cold interpersonal functioning would account for the differences in alexithymia scores between the patient groups.

DESIGN AND METHODS

Participants were 155 primary care patients that were recruited through 52 general practitioners: 52 CFS patients; 52 patients with a chronic cardiovascular or auto-immune disease; 51 patients with a minor medical condition. Interpersonal problems were assessed by means of the Inventory of Interpersonal Problems and alexithymia was assessed by means of the Toronto Alexithymia Scale.

RESULTS

CFS patients and patients with a chronic cardiovascular or auto-immune disease have substantially higher alexithymia scores than patients with a minor medical condition. Alexithymia is positively related to cold and distant interpersonal functioning; negatively related to self-sacrificing and overly accommodating in relation to others; and positively related to vindictiveness and self-centredness. The relation between alexithymia and these interpersonal problems accounts for the differences in alexithymia scores between the patient groups.

CONCLUSIONS

Alexithymia and interpersonal problems should be considered together, in terms of one deficient affect regulatory system, and the relation between alexithymia and specific illness conditions is secondary to this. Clinical assessment of patients with problems in naming and discussing affective states should never be isolated from an examination of their interpersonal problems, and vice versa. Mentalization-based therapy is recommended for patients with problems in naming affective states, interpersonal problems, and concomitant CFS or other alexithymia-related diseases.

Chronic fatigue syndrome, fibromyalgia, and related illnesses: a clinical model of assessment and intervention

A clinically informative behavioral literature on chronic fatigue syndrome (CFS) and fibromyalgia (FM) has emerged over the past decade. The purpose of this article is to (a) define these conditions and their less severe counterparts, i.e., unexplained chronic fatigue (UCF) and chronic widespread pain; (b) briefly review the behavioral theory and intervention literature on CFS and FM; and (c) describe a user-friendly clinical model of assessment and intervention for these illnesses. The assessments described will facilitate understanding of the somewhat unusual and puzzling somatic presentations that characterize these patients. Using an individualized cognitive-behavioral approach the mental health clinician can offer significant help to these often stigmatized and medically underserved patients.

Personality and perfectionism in chronic fatigue syndrome: a closer look

OBJECTIVE

To test the hypothesis that people with chronic fatigue syndrome (CFS) would differ significantly from a healthy control group on measures of general personality and perfectionism, specifically on measures of neuroticism and unhealthy perfectionism.

METHOD

A total of 27 female CFS outpatients and 30 female healthy controls completed questionnaires, including the NEO Personality Inventory-Revised, the Multi-dimensional Perfectionism Scale and measures of anxiety and depression.

RESULTS

The CFS group was significantly more fatigued, anxious and depressed than healthy controls. They scored significantly higher on neuroticism and unhealthy perfectionism. Healthy and unhealthy perfectionism were positively correlated in the CFS group, but not in the control group.

CONCLUSION

The present study confirms the link between neuroticism and fatigue and finds a link between unhealthy perfectionism and fatigue. A 'healthy trait', such as healthy perfectionism, when coupled with evaluative concerns is not necessarily healthy in a fatigued population. Researchers and clinicians should note the context in which apparently benign traits are expressed, and how they interact with other traits.

Unexplained chronic fatigue and interpersonal problems: a study in a primary care population

OBJECTIVE

Unexplained fatigue syndromes are multidimensional phenomena that involve a constellation of symptoms. This article explores whether typical interpersonal problems are associated with self-reported and clinically-rated fatigue symptoms in chronically fatigued patients. We hypothesize that the severity of fatigue symptoms will be associated with a pattern of withdrawal from social interaction.

METHOD

Interpersonal problems were assessed by means of a self-report questionnaire. Chronic fatigue was assessed with a self-report questionnaire (both self-rated and clinically-rated) in a primary care Chronic Fatigue Syndrome (CFS) group (N = 52) and compared with two other clinical populations (minor medical condition: N = 51; chronic organic disease: N = 52).

RESULTS

Compared to patients with a minor medical condition, CFS patients are substantially more fatigued and more socially withdrawn. Compared to patients with a chronic organic disease, somewhat more fatigue-related disability was observed in CFS patients, but no distinct interpersonal problems came to the fore. CFS patients and physicians proved to differ in their opinion on the patient's motivation. In line with the hypothesis, self-rated and clinically-scored fatigue problems proved to be related to a pattern of withdrawal from social interaction.

CONCLUSION

Differences between physicians' and patients in how symptoms are interpreted might be related to patients feeling misunderstood and result in social withdrawal.

Premorbid personality in chronic fatigue syndrome as determined by the Temperament and Character Inventory

BACKGROUND

Using the Temperament and Character Inventory (TCI), we examined personality characteristics in patients with chronic fatigue syndrome (CFS) compared with healthy control subjects, and CFS patients with and without psychiatric diseases. There have been no previous reports assessing personality in CFS patients using the TCI.

METHODS

A total of 211 CFS patients and 90 control subjects completed the TCI and the Chalder Fatigue Scale questionnaires.

RESULTS

Compared with control subjects, CFS patients demonstrated significantly lower premorbid Novelty Seeking, and higher Harm Avoidance and persistence. The fatigue score for CFS patients with psychiatric diseases was higher than that for CFS patients without psychiatric diseases. Patients with CFS with psychiatric diseases showed lower premorbid Self-Directedness when compared with CFS patients without psychiatric diseases. The fatigue score was negatively correlated with premorbid Self-Directedness and Cooperativeness, and positively correlated with Harm Avoidance among CFS patients.

CONCLUSION

This study supported the stereotyped image of CFS patients as perfectionists, which is similar to the Persistence score, and neurotics, which is similar to the Harm Avoidance score. Patients displaying greater neuroticisms and poorer social and communication skills, similar to the Self-Directedness and Cooperativeness scores, tend to have intercurrent psychiatry diseases and show more severe symptoms of CFS.

Etiology of chronic fatigue syndrome: testing popular hypotheses using a national birth cohort study

OBJECTIVE

To review the etiology of chronic fatigue syndrome (CFS) and test hypotheses relating to immune system dysfunction, physical deconditioning, exercise avoidance, and childhood illness experiences, using a large prospective birth cohort.

METHODS

A total of 4779 participants from the Medical Research Council's National Survey of Health and Development were prospectively followed for the first 53 years of their life with >20 separate data collections. Information was collected on childhood and parental health, atopic illness, levels of physical activity, fatigue, and participant's weight and height at multiple time points. CFS was identified through self-report during a semistructured interview at age 53 years with additional case notes review.

RESULTS

Of 2983 participants assessed at age 53 years, 34 (1.1%, 95% Confidence Interval 0.8-1.5) reported a diagnosis of CFS. Those who reported CFS were no more likely to have suffered from childhood illness or atopy. Increased levels of exercise throughout childhood and early adult life and a lower body mass index were associated with an increased risk of later CFS. Participants who later reported CFS continued to exercise more frequently even after they began to experience early symptoms of fatigue.

CONCLUSIONS

Individuals who exercise frequently are more likely to report a diagnosis of CFS in later life. This may be due to the direct effects of this behavior or associated personality factors. Continuing to be active despite increasing fatigue may be a crucial step in the development of CFS.

Personality and chronic fatigue syndrome: Methodological and conceptual issues

Among clinical psychologists, consulting physicians, scientific researchers and society in general an image has emerged of patients with chronic fatigue syndrome (CFS) as perfectionist, conscientious, hardworking, somewhat neurotic and introverted individuals with high personal standards, a great desire to be socially accepted and with a history of continuously pushing themselves past their limits. The aim of this article is to (a) give a concise review of the main recent studies on personality and CFS, (b) address the major methodological problems in the study of personality in CFS and (c) discuss some of the conceptual assumptions that seem to limit the research on personality and CFS. The results of the reviewed studies range from no evidence of major differences between the personalities of patients with CFS and controls, to evidence of severe psychopathology and personality disorder in patients with CFS. Although personality seems to play a role in CFS, it is difficult to draw general conclusions on the relation between personality and CFS. It is argued that this is partially due to the diversity and heterogeneity in study methods, patient populations, control groups and CFS case definitions. Personality should be regarded as an important factor to be studied in CFS. However, additional studies are needed, not focusing exclusively on personality disorder, or personality considered on a general trait level. In recent developments in personality research, the continually evolving life narrative that makes sense of, and gives direction to, an individual's life is also regarded as an important aspect of personality. New insights into personality and CFS might be gained by systematically studying the self-narratives of patients with the syndrome.

Alexithymia in chronic fatigue syndrome: associations with momentary, recall, and retrospective measures of somatic complaints and emotions

OBJECTIVE

The relationship between alexithymia and real-time momentary symptom assessments has not been reported. This cross-sectional study hypothesized that alexithymia would be a predictor of somatic symptoms using three different types of symptom measurement (momentary, recall, and retrospective) in the medically unexplained illness of chronic fatigue syndrome (CFS). In addition, it was hypothesized that negative affect would be a significant mediator of the relationship between alexithymia and somatic symptoms. Finally, the relation of alexithymia to physical illness attribution (a CFS illness predictor) was explored.

METHODS

Participants were 111 adults with CFS. Alexithymia was assessed with the Toronto Alexithymia Scale. Momentary ratings of current symptoms and affect were recorded in electronic diaries carried for 3 weeks. Weekly recall of these momentary reports was also recorded. Retrospective measures included 6-month ratings of fatigue and pain, the Fatigue Severity Scale, the Brief Pain Inventory-Short Form, a CFS symptom measure, the Beck Depression Inventory-II, the Beck Anxiety Inventory, and an illness attribution rating.

RESULTS

Partial correlations, controlling for age and sex, yielded no significant associations between general or specific forms of alexithymia and momentary ratings of fatigue or pain. On the other hand, a significant association, partially mediated by anxiety scores, was found between a specific form of alexithymia and a retrospective pain measure. Finally, physical illness attribution was not significantly associated with alexithymia.

CONCLUSION

Based on assessments of real-time and retrospectively measured symptoms, these data provided only modest support for the alexithymia construct as a predictor of somatic symptoms in people with CFS.

Alexithymia, risk factor or consequence of work-related stress?

BACKGROUND

Primary alexithymia has been proposed as a trait-like risk factor for various psychiatric disorders. Alternatively, secondary alexithymia has been conceptualized as an inadequate coping reaction to a stressful situation. This study investigated the level and the type of alexithymia associated with occupational stress.

METHOD

On 2 occasions, 69 patients with work-related stress and 62 healthy participants completed self-report instruments to measure alexithymia (20-item Toronto Alexithymia Scale), burnout complaints (Maslach Burnout Inventory) and general distress complaints (Depression Anxiety Stress Scales, Checklist Individual Strength). Group differences in alexithymia were analyzed using ANOVAs. The type of alexithymia was investigated by (a) determining absolute and relative stability, (b) exploring state dependence by adjusting alexithymia for burnout and distress complaints and (c) associating recovery of complaints with change in alexithymia.

RESULTS

Alexithymia was significantly elevated among patients. In the patient group, absolute stability of two alexithymia dimensions (identifying feelings, describing feelings) and relative stability of one alexithymia dimension (identifying feelings) was lower than in the healthy group. Cross-sectional group differences became small and nonsignificant after adjustment for distress complaints. Among patients, change in alexithymia was moderately associated with symptom recovery.

CONCLUSION

Elevated alexithymia among patients with occupational stress is highly state dependent, which indicates the presence of secondary alexithymia.

Chronic fatigue syndrome: the need for subtypes

Chronic fatigue syndrome (CFS) is an important condition confronting patients, clinicians, and researchers. This article provides information concerning the need for appropriate diagnosis of CFS subtypes. We first review findings suggesting that CFS is best conceptualized as a separate diagnostic entity rather than as part of a unitary model of functional somatic distress. Next, research involving the case definitions of CFS is reviewed. Findings suggest that whether a broad or more conservative case definition is employed, and whether clinic or community samples are recruited, these decisions will have a major influence in the types of patients selected. Review of further findings suggests that subtyping individuals with CFS on sociodemographic, functional disability, viral, immune, neuroendocrine, neurology, autonomic, and genetic biomarkers can provide clarification for researchers and clinicians who encounter CFS' characteristically confusing heterogeneous symptom profiles. Treatment studies that incorporate subtypes might be particularly helpful in better understanding the pathophysiology of CFS. This review suggests that there is a need for greater diagnostic clarity, and this might be accomplished by subgroups that integrate multiple variables including those in cognitive, emotional, and biological domains.

'I am not the kind of woman who complains of everything': illness stories on self and shame in women with chronic pain

In this study, we explore issues of self and shame in illness accounts from women with chronic pain. We focused on how these issues within their stories were shaped according to cultural discourses of gender and disease. A qualitative study was conducted with in-depth interviews including a purposeful sampling of 10 women of varying ages and backgrounds with chronic muscular pain. The women described themselves in various ways as 'strong', and expressed their disgust regarding talk of illness of other women with similar pain. The material was interpreted within a feminist frame of reference, inspired by narrative theory and discourse analysis. We read the women's descriptions of their own (positive) strength and the (negative) illness talk of others as a moral plot and argumentation, appealing to a public audience of health personnel, the general public, and the interviewer: As a plot, their stories attempt to cope with psychological and alternative explanations of the causes of their pain. As performance, their stories attempt to cope with the scepticism and distrust they report having been met with. Finally, as arguments, their stories attempt to convince us about the credibility of their pain as real and somatic rather than imagined or psychological. In several ways, the women negotiated a picture of themselves that fits with normative, biomedical expectations of what illness is and how it should be performed or lived out in 'storied form' according to a gendered work of credibility as woman and as ill. Thus, their descriptions appear not merely in terms of individual behaviour, but also as organized by medical discourses of gender and diseases. Behind their stories, we hear whispered accounts relating to the medical narrative about hysteria; rejections of the stereotype medical discourse of the crazy, lazy, illness-fixed or weak woman.

Objective assessment of personality disorder in chronic fatigue syndrome

OBJECTIVES

This study aims to objectively assess the prevalence and nature of personality disorders in depressed and nondepressed chronic fatigue syndrome (CFS) patients and compare this to depressed and healthy control groups.

METHODS

Sixty-one patients attending a tertiary referral clinic with chronic fatigue syndrome, 40 psychiatric inpatients with depressive disorder and 45 healthy medical students completed the Structured Clinical Interview for DSM-III-R Diagnoses (SCID-II) in addition to providing routine clinical and demographic information.

RESULTS

Thirty-nine percent of the CFS group, 73% of the depressed group and 4% of the healthy group were diagnosed with personality disorders. Cluster C disorders were the most common in both the CFS and depressed group. The depressed CFS patients had more Cluster B personality disorders than nondepressed CFS patients. Overall for CFS patients there was no association between mood state and personality disorder.

CONCLUSIONS

High levels of personality disorder are found on objective assessment of CFS patients attending a teaching hospital clinic. This cannot be accounted for by comorbid depression.

Correlations between trait anxiety, personality and fatigue: study based on the Temperament and Character Inventory

OBJECTIVE

In our study, we explored the associations among anxiety, the dimensions of Cloninger's theoretically based and empirically validated psychobiological model of personality (Temperament and Character Inventory, TCI) and fatigue in order to clarify the personality risk factors for fatigue.

METHODS

Fifth-year students (n=89) and freshmen (n=162) at Saga Medical School and psychiatric outpatients of Saga Medical School Hospital (n=101) were investigated with the State-Trait Anxiety Inventory (STAI, Japanese version), the TCI (Japanese version), the General Health Questionnaire (GHQ-30) and the self-rating Fatigue Symptom Checklist (FSC), which describe fatigue along three subscales (general, physical and psychological fatigue). Correlation and ANOVA analyses were performed in this study.

RESULTS

The analysis identified a significant relation (P<.0005) between trait anxiety and fatigue. The TCI dimension of harm avoidance (HA) is positively correlated with both trait anxiety and fatigue (general fatigue, psychological fatigue and physical fatigue). The character dimension of self-directedness is negatively correlated with both trait anxiety and fatigue.

CONCLUSIONS

There is an inherent relationship among trait anxiety, the temperament dimension of harm avoidance, character dimension of self-directedness and fatigue. The TCI dimensions, harm avoidance and self-directedness, might be considered as predictors for fatigue-related disorders.

Psychiatric morbidity in the chronic fatigue syndrome: are patients with personality disorder more physically impaired?

OBJECTIVE

The long-term consequences of chronic fatigue syndrome (CFS) include substantial impairment in physical functioning and high levels of work disability. In the absence of a medical explanation for this impairment, some have speculated that it may be due to comorbid psychiatric illness or personality disorder. We addressed this possibility by comparing the functional status of three CFS groups: no psychiatric diagnosis, psychiatric illness only, psychiatric illness and personality disorder. A second aim of the study was to determine whether a continuous measure of psychological distress could provide a better account of impairment than psychiatric diagnosis.

METHOD

The study sample consisted of 84 consecutive female referrals with CFS. All participants satisfied the case definition and completed an assessment protocol consisting of: physical examination, psychiatric interview and self-report questionnaires.

RESULTS

Psychiatric illness, either alone or in combination with a comorbid personality disorder, was not associated with physical impairment or disability in female participants. A regression model of physical functioning found that psychological distress accounted for 6% and symptom severity for 41% of the variance (P=.06 and <.01, respectively). In the case of disability, the corresponding percentages were 2% and 18% (NS and P<.01, respectively). The modest effects of psychological distress could not be attributed to symptom severity.

CONCLUSIONS

Although psychiatric illness and personality disorder was prevalent, neither could explain the effects of CFS on physical functioning and disability. As yet, there is no psychological or medical explanation for the behavioral consequences of CFS.

Alexithymia and somatisation: quantitative review of the literature

OBJECTIVE

To present a quantitative review of the empirical literature on somatisation and alexithymia.

METHODS

Medline and PsycLIT searches for relevant studies were conducted. Meta-analytical techniques were applied to quantify the strength of the associations that were found.

RESULTS

A small to moderate relationship was found between general alexithymia and somatic symptom reporting. The alexithymia dimension measuring difficulty in identifying feelings showed the strongest association with symptom reports. The alexithymia dimension measuring externally oriented thinking was virtually unrelated to somatic symptom reports. Compared to healthy control populations, subjects suffering from a somatoform condition were significantly more alexithymic, with effect sizes ranging from moderate to large. The studies comparing somatoform to medical or psychiatric conditions yielded inconclusive results.

CONCLUSIONS

By means of quantitative procedures, an association between general alexithymia and somatic symptom reporting was established. Due to the use of questionnaires that can only check for symptoms, not whether these symptoms are medically explained or not, it is however not possible to draw conclusions on somatisation properly defined. The inconsistent results found when comparing somatoform conditions to medical and psychiatric controls may be attributed to confounding variables. In future studies, these variables should be statistically controlled to establish a more consistent pattern of associations between somatoform conditions and alexithymia. It is, however, equally feasible that this inconsistency reflects the nonspecific character of the association between alexithymia and somatisation. The presence of only one prospective study does not allow to draw conclusions on alexithymia as a predisposing factor for somatisation.

Recovering from subarachnoid haemorrhage: patients' perspective

Healthcare professionals generally accept that a good recovery following subarachnoid haemorrhage (SAH) equates to one where there is an absence of physical deficit. There does not appear to be a general acceptance of the impact of the less obvious invisible or psychological difficulties. Therefore, this study aimed to illuminate the experience of recovery from SAH. Using a qualitative methodology, eight participants were interviewed using a semi-structured approach. Individual data were handed to the participant for the purpose of confirming the accuracy of the summary made by the author. Data were then analysed for similar and contrasting themes. As a result, the study offers an insight into how common psychological difficulties may impact on a person's ability to make a full and complete recovery following SAH. In conclusion, the main themes generated by the data are presented and recommendations for practice in meeting the needs of participants are offered.

Leisure sickness: a pilot study on its prevalence, phenomenology, and background

AIM

To explore the prevalence, phenomenology, and background of leisure sickness, i.e., the condition of people developing symptoms of sickness during weekends and/or vacations.

METHOD

In order to obtain an estimate of its prevalence, a representative Dutch sample consisting of 1,128 men and 765 women was asked to indicate to what extent they recognized themselves in our description of weekend and vacation sickness. For the investigation of the phenomenology and background of this condition and the characteristics of the patients suffering from it, questionnaire data were collected in new samples consisting of 114 cases and 56 controls. Questions referred to symptoms, onset, duration, appreciation of weekend and vacation activities, and appraisal of work and workload.

RESULTS

In the case of male respondents, 3.6 and 3.2% recognized themselves in the description of the weekend and the vacation syndrome, respectively, compared with 2.7 and 3.2% women. Most frequently reported symptoms were headache/migraine, fatigue, muscular pains, and nausea. In addition, viral infections (flue-like, common cold) were often reported in relation to vacations. Cases had generally suffered from leisure sickness for over 10 years and the onset was associated with stressful conditions. They attributed their condition to difficulties with the transition from work to nonwork, stress associated with travel and vacation, as well as workload and personality characteristics. There were no significant group differences in the appreciation of weekend and leisure activities or lifestyle during days off. Most striking differences were found with respect to experienced workload, sense of responsibility, and inability to relax.

CONCLUSION

Leisure sickness is a relatively common condition. Specific lifestyle factors or leisure activities seem to be less relevant for its development. Concerning risk factors, the data tend to point to high workload and person characteristics, namely, the inability to adapt to the nonworking situation, a high need for achievement, and a high sense of responsibility with respect to work. Future studies should be designed for testing specific hypotheses concerning the underlying mechanisms and evaluating the effectiveness of psychological and/or physical activity interventions.
