This report summarizes the health behaviors and psychological characteristics of fifteen male marathon runners who were first tested in 1969 (N = 8) and 1976 (N = 7). The participants in this study averaged 29 years of age at the outset, and the mean age at the time of follow-up was 50 years. These subjects were found to score in the normal range on all of the psychological variables, and they were characterized by the "iceberg" profile described earlier for elite athletes in various sports. This profile includes scores that fall below the population average on mood states such as tension, depression, anger, fatigue and confusion along with above average scores on vigor. Also, the psychological traits of these former runners have been remarkably stable across the past two decades, with the exception that a uniform decline has been observed for the neuroticism measure. Earlier research by Eysenck has shown that neuroticism decreases with age. These former marathon runners continue to be moderately active, and it is noteworthy that they first became involved as runners while in high school. All but one of the participants had attended college, and each had participated in competitive running while in college. Training for marathon competition took place following the college years. It is likely that much of the early success enjoyed by this group was governed to a substantial degree by heredity. This sample possessed an average aerobic power of 70 ml.kg-1.min-1 along with a unique somatotype when first tested, and these factors are known to have a substantial heritability component. The health behaviors studied in this group were uniformly positive. They were found to be physically active, and their physical self-esteem fell above that of other men in their age group. The subjects reported moderate use of alcohol, no insomnia, few physical problems and good overall mood. The sample of former marathon runners described in this report is unique in a number of respects, and caution is urged in making generalizations. With this qualification in mind, it is concluded that a lifetime of regular physical activity is associated with desirable physical and mental health.

Perfectionism has been implicated as a vulnerability factor in the development of chronic unexplained fatigue. In the present study, different components of fatigue and perfectionism were studied in 121 female nurses. They completed a postal questionnaire assessing current (state) and usual (trait) fatigue, and dimensions of personality including six components of perfectionism. Night-shift work was associated with state, but not trait, fatigue. Negative, but not positive, components of perfectionism were associated with mental trait fatigue in particular, but also with physical trait fatigue. In contrast, the associations with positive perfectionism tended to be inverse. Multiple regression modeling indicated that neuroticism as well as negative perfectionism were separately associated with trait fatigue. We suggest that negative aspects of perfectionism may cause maladaptive coping strategies which predispose individuals to fatigue.

The aim of this study was to evaluate psychosocial quality of life after heart transplantation. We examined 29 patients (25 M and 4 F), average age was 43.5 y (18-62 y). The age at time of heart transplantation was 43 years (17-55 y). The time after heart transplantation was 3.3 year (0.3-9 y). Spielberger's Questionnaire of Anxiety, Knobloch's inventory of neuroticism, Freiburg's Personality Inventory and Quality of Life Inventory were used, 33% of patients demonstrated increasing frequency and 29% of patients increasing intensity of neurotic symptoms. 23% of patients presented increasing levels of anxiety (as a state). The personality dimensions (depression, excitability and low emotional stability) displayed high frequency. The results showed that patients were more satisfied with family support, with sexual activities, and less satisfied with financial situation, social activities, social isolations, sleep, memory, excitability, fatigue. 41.5% of patients returned back to work. The results indicate that these psychosocial factors play an important role in quality of life after heart transplantation. That is why if is necessary to dedicate an increasing attention to them. (Tab. 1, Fig. 6, Ref. 14.)

This study tests the hypothesis that a discrepancy between resources and demands explains most of the variance in fatigue in cancer patients undergoing radiotherapy. Patients (n=250) were interviewed at pretreatment, posttreatment, and at 9-month follow-up. Resources involved physical condition, neuroticism, optimism, social support, gender, age, and level of education. Demands entailed prognosis, radiotherapy dose, the effort associated with actual activity, and the patient's perception of overall burden. Regression analyses were performed, using interaction terms to operationalize the discrepancy between resources and demands. The hypothesis was not supported. At pretreatment, physical condition explained most of the fatigue, whereas, at posttreatment, both the patients' physical condition and perception of burden contributed to fatigue. At follow-up, demands did not add to the variance already explained by resources, and vice versa. Factors that contribute to the patient's physical condition before starting radiotherapy and to his/her perception of burden need to be addressed to further our understanding of their fatigue.

In this study, insomnia in 80-year-olds was related to medical, psychological and social factors. The data were based on examinations every year in people aged between 80 and 89 years. Of 333 people living in the city of Lund and born in 1908, 67% participated. Increased severity of insomnia was significantly associated with use of diuretics, other cardiovascular drugs, hypnotics and laxatives, and with nervousness, difficulty relaxing, anorexia, nausea, constipation, backache, feeling cold, sweating, loss of weight, dizziness, depression, general fatigue, exhaustion, angina pectoris, cardiac insufficiency, worsened objective and subjective health, presence of negative T-waves on ECG, anxiety, total life satisfaction, neuroticism, disbelief in a just world, feeling lonely and lower survival rates. Thus insomnia has widespread associations with different aspects of life in 80-year-olds.

Fourteen common physical symptoms are responsible for almost half of all primary care visits. Only about 10% to 15% of these symptoms are found to be caused by an organic illness over a 1-year period. Patients with medically unexplained symptoms are frequently frustrating to primary care physicians and utilize medical visits and costs disproportionately. This paper will review the relationship between psychological distress and the decision to seek medical care for common physical symptoms such as fatigue and headache. Evidence will be presented demonstrating that an increasing number of medically unexplained symptoms over a patient's lifetime correlate linearly with the number of anxiety and depressive disorders experienced, the score on the personality dimension of neuroticism, and the degree of functional impairment. Several scales measuring somatization and hypochondriasis are recommended for primary care and medical specialty patients.

When exposed to infectious pathogens, human beings manifest variability in the incidence and severity of infection. This variability may partly depend on psychological variables, which have long been thought to contribute to the predisposition, onset, and course of various physical illnesses, including infectious diseases. The objective of the study was to investigate the predictive value of several personality and other psychological variables on antibody titers and fatigue following a specific viral infection. Subjects were divided into a seronegative group (not immune prior to vaccination) (N = 60) and a seropositive group (immune prior to vaccination) (N = 180), based on antibody titers to rubella before and 10.5 weeks after vaccination with live-attenuated rubella virus. Questionnaires assessing externalizing, internalizing, self-esteem, neuroticism, and fatigue-related symptoms were administered to the subjects before vaccination. Fatigue-related symptoms were re-evaluated 10 weeks post vaccination. In the seronegative group, low titers of rubella antibodies, 10.5 post-vaccination, were predicted by high internalizing or neuroticism scores, and by low self-esteem, measured at baseline. Higher externalizing scores indirectly predicted lower titers of antibodies, via fatigue-related symptoms, measured 10 weeks post vaccination. In contrast, in the seropositive group no association was found between any of the psychological variables and antibody titers. Personality and other psychological variables can predict antibody titers to rubella vaccination, in infected individuals. The associations between the psychological variables and antibody titers are complex, and involve both direct and indirect associations. Specific psychological variables can also be used to predict levels of post-vaccination fatigue.

The main areas studied until the 70s were fatigue and rest. Many tests for fatigue were examined, and studies failed to find their practical use. Fatigue grows according to the positive acceleration curve while recovery grows according to the negative acceleration curve. Different mechanisms are involved in intelligence test performance when subjects are fatigued and when rested. Contrary to the pharmacological, psychological stimulants increase performance without adverse effects on the organism. The differences in absenteeism between male and female workers are related to family duties. After the 70s, research was focused on shiftwork. Shiftwork is associated with imposed change in a worker's normal activity pattern. It brings about fatigue, negative moods, and impaired health, sleep, safety, and working capacity. The shiftwork tolerance is connected with introversion, neuroticism, morningness, control of behavioural arousal, and parameters of circadian rhythms. The most important predictors of shiftwork tolerance are dimensions of control of behavioural arousal and morningness, while the most important criterion is sleep quality.

This article deals with the history of the terminological and nosological development of the concept neurasthenia introduced in 1869 by George Miller Beard and in particular with its reappearance in western medicine in the 1980 s. Beginning with its predecessors in antiquity and continuing with hypochondria, which became a fashionable disease in the 18 th century, the concept neurasthenia reached a high point and world-wide medical acceptance at the end of the 19 th/beginning of the 20 th century. However, between the 1930 s and 1960 s it declined in popularity and gradually disappeared until finally it only had a rudimentary nosological role in the term "pseudoneurasthenia". In the countries of the Far East, on the contrary, the concept of neurasthenia has been in continual use since its importation in the first decades of the last century. In the 1980 s, when an interest in the symptoms of chronic fatigue was reawakened in western medicine, the concept neurasthenia reappeared, this time to define the particular form of a neurotic disorder. Parallel to these developments increasing importance was attached to clinical descriptions of illnesses which on account of their similarity to the symptoms of neurasthenia could be termed modern variants of the concept neurasthenia. These are "Chronic-Fatigue-Syndrome", "Fibromyalgia" and "Multiple Chemical Sensitivities" which have more or less adopted the organic inheritance of Beard's former concept of neurasthenia, despite the fact that so far the question of organicity could not be decisively answered in a single case. In order to clarify possible influences on the development of the concept neurasthenia and its variants, the theories and ideas of E. Shorter, medical historian at the University of Toronto, are discussed in the final part of the article, whereby the particular cultural background in each case has a decisive influence on the manifestation of the psychosomatic symptoms.

Liver transplantation is a well-established treatment for liver failure. Prolongation in survival is accepted, but long-term effects of liver transplantation on cognitive and psychological outcome are unclear. In the present study, psychological data were prospectively collected for 164 patients who were assessed for liver transplantation. Memory impairment, psychomotor slowing, anxiety, and depression were commonly observed. Severity of liver disease at assessment was significantly associated with slowing of reaction time. Memory impairment distinguished those who were not listed for transplantation because of illness severity. One year posttransplantation, follow-up data from transplant recipients showed significant improvement in most psychological domains relative to both healthy comparison participants and patients with chronic liver disease who did not undergo transplantation. Immunosuppression (cyclosporine versus tacrolimus) did not have differential effects on quality of life, fatigue, or affective status, although those administered cyclosporine showed greater improvements at 1-year follow-up on simple and choice reaction times. Elevated levels of anxiety and neuroticism at pretransplantation assessment were associated with worse psychosocial outcome at 1 year posttransplantation. Severity of liver disease was not related to psychological outcome at 1 year. Good psychological outcome at 1 year was maintained at the 3-year follow-up.
