Do all roads lead to Rome? An ideal-type study on trajectories of resilience in advanced cancer caregiving.

OBJECTIVE: Studies on resilience in advanced cancer caregiving typically focus on the interplay between resilience-promoting resources and coping strategies that may be associated with resilience. However, no studies have investigated the emergence of trajectories of resilience and distress in individuals confronted with a cancer diagnosis of a loved one. METHODS: Ideal-type analysis, a method for constructing typologies from qualitative data, was used to identify trajectories involving resilience or the lack thereof based on fifty-four interviews conducted with seventeen partners of patients recently diagnosed with advanced cancer over a period of three years. FINDINGS: Six trajectories could be distinguished, three of which involved resilience (rapidly adapting resilience, gradually adapting resilience, and slowly adapting resilience), while the other three trajectories (continuing distress, delayed distress, and frozen disconnection) reflected a less optimal adjustment. These different trajectories seemed to be rooted in the individual characteristics of partners, the behavior of a support network, and interactions between the two. CONCLUSION: The differentiation between these trajectories in partners of patients diagnosed with cancer not only furthers research on resilience in the face of adversity, but also promises to assist healthcare professionals in optimizing support for this often-neglected group of partners of patients diagnosed with cancer.

Video-retroalimentación focalizado en los recursos para mejorar la sensibilidad en díadas madre-infante con síntomas depresivos: protocolo de un ensayo clínico aleatorizado piloto / Strength-based video-feedback to improve maternal sensitivity in mother-infant dyads with maternal depressive symptoms: study protocol for a randomized controlled feasibility trial

INTRODUCTION: Maternal sensitivity and mentalization are fundamental for children's mental health development. These skills have been negatively associated with maternal postpartum depressive symptomatology. Moreover, its prevalence increases in low socioeconomic and psychosocial risk contexts, where the access to treatment is scarce. Even though Attachment Based Interventios, such as Video-Feedback has been internationally recognized as an effective intervention. Its cost, as well as the need for language translation and cultural adaptation makes it difficult to implement in Latinamerican countries. AIM: The present study aims to assess the feasibility and acceptability of an online Video-Feedback intervention informed n mentalization aimed at mother-infant dyads with depressive symptomatology who attend Chilean public health centers. METHOD: This is a pilot randomized clinical trial with two groups of 60 mother-infant dyads between 4 and 12 months of age. Participants will be randomly assigned to control and experimental groups in a 1:1 ratio. Even though both groups will receive usual treatment, the experimental group will also receive the present video-intervention. At the end of the study, feasibility will be assessed based on focus groups aimed at interveners and quantitative outcomes such as recruitment rate, questionnaire completion rate and intervention completeness. Acceptability will be assessed from in-depth interviews with participants. In addition, effect sizes of primary and secondary outcomes will be calculated. EXPECTED RESULTS: Results are expected to generate parameters to design a larger-scale clinical trial and to preliminary assess the effect of the reported mentalization-informed intervention on maternal sensitivity. Additionally, it seeks to contribute with a mental health intervention for low-income mother-infant dyads, which can be implemented remotely, at a low cost, and that would be suitable for implementation at a mental health care system policy. The protocol of this trial's design was registered at Clinical Trials (NCT04748731).

INTRODUCCIÓN: La sensibilidad y la mentalización materna constituyen competencias fundamentales para el desarrollo de la salud mental infantil. A su vez, dichas habilidades han sido negativamente asociadas con la presencia de sintomatología depresiva postparto, la cual aumenta su prevalencia en contextos de bajo nivel socioeconómico y riesgo psicosocial, en donde el acceso a tratamiento escasea. Paralelamente, si bien internacionalmente el video-retroalimentación constituye una herramienta efectiva en intervenciones basadas en el apego, el costo, idioma y necesidad de adaptación cultural dificultan su implementación en países latinoamericanos. OBJETIVO: Evaluar la factibilidad y aceptabilidad de una video-intervención informada por la mentalización, dirigida a díadas madre-bebé con sintomatología depresiva, atendidas en centros públicos de atención en salud mental en Chile. MÉTODOS: Ensayo clínico aleatorio piloto con dos grupos de 60 díadas madre-bebé de entre 4 y 12 meses de edad, quienes serán asignados aleatoriamente a grupos control y experimental en una proporción de 1:1. Si bien ambos grupos recibirán el tratamiento habitual, el grupo experimental recibirá también la video-intervención. Al término del estudio se evaluará la factibilidad a partir de grupos focales dirigidos a interventores e indicadores de resultados cuantitativos tales como tasa de reclutamiento, de completación de cuestionarios y finalización de la intervención. La aceptabilidad se evaluará a partir de entrevistas en profundidad a las participantes. Adicionalmente se calculará tamaño del efecto de indicadores de resultados primarios y secundarios. RESULTADOS ESPERADOS: Se espera que los resultados del estudio generen parámetros para diseñar un ensayo clínico de mayor escala y evaluar preliminarmente el efecto de la intervención informada en la mentalización en la sensibilidad materna. Se busca además contribuir con una intervención en salud mental basada en la teoría del apego dirigida a díadas madre-bebé de bajos ingresos, que pueda ser implementada de manera remota, a bajo costo y apta para ser escalada a los sistemas de atención en salud mental.

Abstract: Objective: To understand the relationship between attachment and diabetes and the role of stress mediators in children with type 1 diabetes (T1D) and their mothers. Material and Method: The following assessment instruments were applied as self-report measures: Attachment Scale (ECR- R), Perceived Stress Scale (PSS), Security Scale (SS), and the Stress in Children (SiC) questionnaire, which were completed by children and their mothers. We analyzed demographic variables, diabetes onset time, and the average of the last three glycosylated hemoglobin (HbA1c) measurements as a parameter of metabolic control in the last year. Results: Attachment strategies of both mother and child, as well as maternal stress, showed a significant association with the child's diabetes outcomes, although with important gender differences. Conclusions: Both mother and child attachment strate gies are relevant aspects of the T1D course.

Glucocorticoid receptor DNA methylation and childhood trauma in chronic fatigue syndrome patients.

OBJECTIVE: Although the precise mechanisms are not yet understood, previous studies have suggested that chronic fatigue syndrome (CFS) is associated with hypothalamic-pituitary-adrenal (HPA) axis dysregulation and trauma in early childhood. Consistent with findings suggesting that early life stress-induced DNA methylation changes may underlie dysregulation of the HPA axis, we previously found evidence for the involvement of glucocorticoid receptor (GR) gene (NR3C1) methylation in whole blood of CFS patients. METHODS: In the current study, we assessed NR3C1-1F region DNA methylation status in peripheral blood from a new and independent sample of 80 female CFS patients and 91 female controls. In CFS patients, history of childhood trauma subtypes was evaluated using the Childhood Trauma Questionnaire short form (CTQ-SF). RESULTS: Although absolute methylation differences were small, the present study confirms our previous findings of NR3C1-1F DNA hypomethylation at several CpG sites in CFS patients as compared to controls. Following multiple testing correction, only CpG_8 remained significant (DNA methylation difference: 1.3% versus 1.5%, p<0.001). In addition, we found associations between DNA methylation and severity of fatigue as well as with childhood emotional abuse in CFS patients, although these findings were not significant after correction for multiple testing. CONCLUSIONS: In conclusion, we replicated findings of NR3C1-1F DNA hypomethylation in CFS patients versus controls. Our results support the hypothesis of HPA axis dysregulation and enhanced GR sensitivity in CFS.

Cortisol and Subjective Stress Responses to Acute Psychosocial Stress in Fibromyalgia Patients and Control Participants.

OBJECTIVE: Hypothalamic-pituitary-adrenal axis dysfunction may play a role in fibromyalgia (FM) pathogenesis but it remains understudied in this disorder. Furthermore, early childhood adversities (ECA) are common in FM, but whether they moderate stress reactivity is unknown. Hence, we investigated cortisol and subjective responses to acute psychosocial stress in FM and controls, while adjusting for ECA. METHODS: Twenty-seven female FM patients and 24 age-matched female controls were recruited in a tertiary care center and through advertisements, respectively. The Childhood Trauma Questionnaire was used to measure ECA history. Salivary cortisol levels and subjective stress ratings were measured at multiple time points before and after the Trier Social Stress Test (TSST) was administered. RESULTS: Significant main effects of group [F(1,43) = 7.04, p = .011, lower in FM] and ECA [F(1,43) = 5.18, p = .028, higher in participants with ECA] were found for cortisol responses. When excluding controls with ECA (n = 5), a significant group-by-time interaction was found [F(6,39) = 2.60, p = .032], driven by a blunted response to the stressor in FM compared with controls (p = .037). For subjective stress responses, a significant main effect of group [F(1,45) = 10.69, p = .002, higher in FM] and a trend toward a group-by-time interaction effect [F(6,45) = 2.05, p = .078, higher in FM 30 minutes before and 30 and 75 minutes after the TSST, and impaired recovery (difference immediately after - 30 minutes after the TSST) in FM] were found. CONCLUSIONS: Blunted cortisol responsivity to the TSST was observed in FM patients compared with controls without ECA. FM patients had higher subjective stress levels compared with controls, particularly at baseline and during recovery from the TSST. In FM patients, ECA history was not associated with cortisol or subjective stress levels or with responsivity to the TSST. Future research should investigate the mechanisms underlying hypothalamic-pituitary-adrenal axis dysregulation in FM.

Self-critical perfectionism predicts lower cortisol response to experimental stress in patients with chronic fatigue syndrome.

OBJECTIVE: Previous studies have suggested that self-critical perfectionism (SCP) may play a role in the development and maintenance of Chronic Fatigue Syndrome (CFS). In this study we investigated whether SCP is related to a hypofunction of the hypothalamic-pituitary-adrenal (HPA) axis, which has been shown to be a key factor in the pathophysiology of CFS. METHOD: We conducted a quasi-experimental study to examine the association between SCP (as measured with the Depressive Experiences Questionnaire) and stress reactivity in a sample of 41 female CFS patients. Participants were exposed to the Trier Social Stress Test (TSST). Both subjective stress and salivary cortisol levels were measured until 90 min after the TSST. We also examined the relationship between stress reactivity and illness characteristics (i.e., duration and severity of symptoms). RESULTS: The results showed that SCP was associated with increased subjective stress reactivity, but with decreased HPA-axis reactivity as indicated by a blunted cortisol response to the TSST. Furthermore, we found an inverse relationship between cortisol reactivity and symptom severity. There was no relationship between cortisol reactivity and illness duration. CONCLUSION: Our findings suggest that SCP is associated with loss of resilience of the neurobiological stress response system in CFS.

Changing Communities and Increases in the Prevalence of Depression: is there a Relationship? / Cambios en las comunidades y el aumento en la prevalencia de la depresión: ¿hay una relación?

The article analyses the impact of individualization processes on community-level determinants of health in postmodern societies, taking depression as an example. The analysis shows how the evolution of the broader social context towards forms of organization focused on the individual and on competition in a market economy implies the vanishing of traditional communities and there -fore of their health-supportive functions, thus endangering their ability to fulfill the needs of belonging, mutual support, and identity. The analysis also relates this evolution to cultural phenomena and to recent studies about culture -gene coevolution, implying that the effects of community decline are expected to be even greater in collectivist societies. Through its multidimensional conceptual analysis, this paper aims to contribute to further uncovering the interactions of psychological, psychosocial, and biological factors in mental health.

El artículo analiza el impacto que los procesos de individualización en las sociedades postmodernas tienen sobre los determinantes de salud de nivel comunitario, tomando como ejemplo la depresión. El análisis muestra cómo la evolución del contexto social más amplio hacia formas de organización enfocadas en el individuo y en la competencia de las economías de mercado, implican el desvanecimiento de las comunidades tradicionales y por lo tanto de sus funciones de apoyo a la salud. Es así que ponen en peligro su capacidad para satisfacer las necesidades de pertenencia, apoyo mutuo e identidad. El artículo también relaciona esta evolución con fenómenos culturales y con estudios recientes sobre la coevolución cultura-gen, implicando que los efectos de declinación de la comunidad deberían ser aún mayores en las sociedades colectivistas. A través de su análisis conceptual multidimensional, el artículo busca contribuir a profundizar sobre las interacciones de factores psicológicos, psicosociales y biológicos en salud mental.

The Self beyond Somatic Symptoms: A Narrative Approach to Self-Experience in Adolescent Chronic Fatigue Syndrome.

BACKGROUND: The self and self-experience are often assumed to play an important role in adolescent patients presenting with severe somatic symptoms and bodily distress. Nonetheless, most empirical work on this subject is confined to studies of personality and patients' experience of negative emotionality. This study aims to move beyond mere descriptions of symptoms, traits and distress, and consequently adopts a narrative approach to self-experience in adolescent chronic fatigue syndrome (CFS). SAMPLING AND METHODS: The self-confrontation method (SCM) is a well-validated instrument to systematically analyze narrative self-experience. The SCM was used to study 42 adolescents with CFS, compared to 36 adolescents with juvenile idiopathic arthritis (JIA) and 25 matched healthy controls. The Child Health Questionnaire (CHQ-CF87) was used to assess mental health, self-esteem, and physical and psychosocial functioning. RESULTS: Both patient groups reported significantly less positive self-experience of autonomy and success compared to healthy controls. Furthermore, patients with CFS described significantly more negative self-experience of powerlessness, isolation and unfulfilled longing. In the CHQ-CF87, both patient groups scored significantly lower on physical functioning than controls. Adolescents with CFS also scored significantly lower on mental health and self-esteem. CONCLUSIONS: Adolescent CFS entails a serious threat to the self, which might be inherent to the condition. Not only are patients more impaired in mental health, self-esteem, and physical and psychosocial functioning than patients with JIA, they also suffer from a distinct combination of high negative and low positive self-experience. These findings stress the need for strategies that empower patients towards a 'management of the self'.

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.

Social cognition and levels of personality organization in patients with somatoform disorders: a case-control study.

Social cognition and its association with level of personality organization (PO) were examined in 163 patients with severe somatoform disorders (SFDs) and 151 psychiatric (PSA) control patients. Social cognition was measured with the Social Cognition and Object Relations Scale, which assessed both affective and cognitive facets of social cognition. Levels of PO were assessed using theory-driven profiles of the Dutch Short Form of the Minnesota Multiphasic Personality Inventory (MMPI). The SFD patients exhibited impairments in the cognitive facets of social cognition but not more so than the PSA controls. The results for the affective aspects indicated that the SFD patients exhibited lower levels of emotional investment yet higher affect tone in interactions than the PSA controls. In contrast to the control group, level of PO was not associated with social cognition in SFD. Together, the results indicated that impairments in complexity of mental representations are not specific to SFD patients, yet impairments in emotional investment may be specific to SFD.

Self-critical perfectionism predicts outcome in multidisciplinary treatment for chronic pain.

BACKGROUND: Self-critical perfectionistic personality features have been shown to influence the onset and perpetuation of pain symptoms. However, no study to date has investigated whether these personality features are associated with treatment response in chronic pain. METHODS: Using a naturalistic pre-post design, the present study examined the effect of self-critical perfectionism on treatment outcome in terms of self-reported pain. The study was conducted in a sample of 53 chronic non-cancer pain patients who followed Multidisciplinary Pain Education Program (MPEP), a brief, 2-week cognitive-behaviorally based psycho-educational intervention for chronic pain that was recently found to be effective in reducing pain severity. Pre- and post-treatment pain intensity levels were assessed with the visual analog scale of the McGill Pain Questionnaire-Short Form. RESULTS: Pretreatment self-critical perfectionism was significantly associated with negative treatment outcome, even after taking into account pretreatment levels of depression. CONCLUSION: Results suggest that self-critical perfectionistic personality features may negatively interfere with treatment response in patients with chronic pain. Thus, findings indicate that chronic pain patients with high levels of self-critical perfectionism may benefit less from brief interventions such as MPEP, and therefore may need more intensive and tailored treatment.

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.

Prevalence of DSM-IV personality disorders in patients with chronic fatigue syndrome: a controlled study.

BACKGROUND: It is not yet clear whether chronic fatigue syndrome (CFS) is associated with elevated levels of personality disorders. PURPOSE: This study aims to determine the prevalence of DSM-IV axis II personality disorders among patients with CFS. METHODS: We examined the prevalence of personality disorders in a sample of 92 female CFS patients and in two well-matched control groups, i.e., normal community individuals (N = 92) and psychiatric patients (N = 92). Participants completed the assessment of DSM-IV personality disorders questionnaire (ADP-IV), which yields a categorical and dimensional evaluation of personality disorder features. RESULTS: The prevalence of personality disorders in CFS patients (16.3 %) was significantly lower than in psychiatric patients (58.7 %) and was similar to that in the community sample (16.3 %). Similar results were found for dimensional and pseudodimensional scores, except for the Depressive (DE) and Obsessive-Compulsive Personality Disorder (O-C) subscales. Patients with CFS had significantly higher levels of DE features compared to normal controls and similar dimensional scores on the O-C scale compared to psychiatric controls. CONCLUSIONS: Although the CFS sample was characterized by depressive and obsessive-compulsive personality features, this study provides no evidence for the assumption that these patients generally show a higher prevalence of axis II pathology. Given the conflicting findings in this area, future studies using multiple measures to assess personality disorders in CFS are needed to substantiate these findings.

Is fibromyalgia a discrete entity?

Fibromyalgia (FM) is defined as chronic widespread pain (CWP) with allodynia or hyperalgesia to pressure pain, and is classified as one of the largest group of soft tissue pain syndromes. Its pathogenesis is not entirely understood, although it is currently believed to be the result of a central nervous system (CNS) malfunction that increases pain transmission and perception. There are no instrumental tests to confirm the diagnosis, but many of the differential diagnoses can be excluded by means of an extensive clinical examination and patient history. Although fibromyalgia is a recognisable clinical entity, it would seem appropriate to consider the entire range of tenderness and distress in clinic patients in order to tailor treatment on an individual basis.

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

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 (ß = -0.455, p = 0.001) and severity of depression (ß = -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 (ß = 0.203, ns; ß = 0.003, ns; and ß = 0.154, ns, respectively). Importantly, duration of chronic pain was not related to treatment outcome (ß = 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.

Self-esteem mediates the relationship between maladaptive perfectionism and depression in chronic fatigue syndrome.

Patients with chronic fatigue syndrome (CFS) often experience depression which may negatively affect prognosis and treatment outcome. Research has shown that depression in CFS is associated with maladaptive or self-critical perfectionism. However, currently, little is known about factors that may explain this relationship, but studies in nonclinical samples suggest that low self-esteem may be an important mediator of this relationship. The present study therefore examined whether self-esteem mediated the cross-sectional association between maladaptive perfectionism and severity of depression in 192 patients meeting Centres for Disease Control and Prevention criteria for CFS. Patients completed self-report measures of maladaptive perfectionism, self-esteem, depression, and fatigue. Regression analyses and more direct tests of indirect effects (i.e., the Sobel test and bootstrapping) were used to test for mediation. Congruent with expectations, we found that self-esteem fully mediated the relationship between maladaptive perfectionism and depression in CFS. Findings from this study suggest that self-esteem may explain the link between maladaptive perfectionism and depression in CFS, which may have important implications for the treatment and prevention of depression in these patients.

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.

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.
