Personality and the immune system: models, methods, and mechanisms.

A relationship between personality and the immune system has been hypothesized for at least 25 years, and understanding this relationship could contribute to understanding how personality affects the onset and course of chronic diseases such as cancer and heart disease. A number of personality dimensions, including repression, optimism, hostility, attributional style, and extraversion-introversion, have been related to immune parameters or immunity. Theoretical and methodological issues in interpreting the extant literature and in planning future research include selection of personality dimensions to study, study design, and attention to potential psychosocial mediators. Past and future investigations using sophisticated theory and methodology to investigate the ongoing influence of personality on physiological systems, including the immune system, promise to advance the understanding of both.

Characteristics of early psychosis.

There is little research on characteristics related to course and prognosis of early-onset psychosis. The present article aims to advance our knowledge of this disorder for the purpose of proper diagnosis and treatment. It focuses on premorbid and prodromal characteristics, treatment history, symptoms and classifications, and differences between subgroups with affective and schizophrenic psychosis. A chart review was constructed to study a group of 129 subjects (12-18 years) with psychotic symptoms referred to the University Medical Center in Utrecht. The group was characterized by early-but nonspecific-treatment, developmental problems (mostly social), and clear prodromal symptoms. Drug abuse, depressive symptoms, and suicidal behavior were also frequent. Male sex, a relatively long prodromal phase, school problems, and drug abuse were more indicative of the schizophrenic subgroup. Introversion was characteristic for boys with schizophrenia. Classifications, however, were not stable. These findings suggest that early recognition of psychosis can be enhanced in health and youth care facilities. Careful examination of the prodromal phase seems helpful to differentiate between schizophrenic and affective psychosis.

Impact of pulmonary rehabilitation on psychosocial morbidity in patients with severe COPD.

STUDY OBJECTIVE: To assess the effect of pulmonary rehabilitation (PR) on psychosocial morbidity, functional exercise capacity, and health-related quality of life (HRQL) in patients with severe COPD. DESIGN: A prospective, randomized, controlled trial with blinding of outcome assessment and data analysis. SETTING: A tertiary-care respiratory service. PATIENTS: Forty patients (mean age, 65 +/- 8 years [+/- SD]) with severe chronic flow limitation (FEV(1), 35 +/- 13%) without respiratory failure (Pao(2), 72 +/- 9 mm Hg; Paco(2), 42 +/- 5 mm Hg) were randomized either to a control group or to a PR group (PRG). INTERVENTIONS: Sixteen weeks of PR that included breathing retraining and exercise. MEASUREMENTS: At baseline and 16 weeks, we evaluated psychosocial morbidity using two questionnaires (the Millon Behavior Health Inventory [MBHI] and the Revised Symptom Checklist [SCL-90-R]) and measured 6-min walk distance (6WMD) and HRQL using the Chronic Respiratory Questionnaire (CRQ). RESULTS: We found differences in favor of the PRG in the following MBHI domains: introversive, forceful, and sensitive personality styles (all p </= 0.05) and chronic tension (p </= 0.01). Results of the depression, hostility, global severity, positive symptom distress index (all p </= 0.01), somatization, anxiety, psychoticism, and positive symptom (all p </= 0.05) domains of the SCL-90-R favored the PRG. We also found statistically and clinically significant differences between groups in 6MWD (85 m; p < 0.01) and in two domains of the CRQ: dyspnea (1.0; p < 0.01) and mastery (0.6; p < 0.05). The other two domains of CRQ showed strong trends in favor of PRG: 0.7 for both fatigue and emotional function (minimal important difference, 0.5). CONCLUSIONS: PR may decrease psychosocial morbidity in COPD patients even when no specific psychological intervention is performed. Findings from this study also confirm the positive impact of PR on functional exercise capacity and HRQL.

Trait shyness in the elderly: evidence for an association with Parkinson's disease in family members and biochemical correlates.

The emergence of potential treatments to slow the progression of idiopathic Parkinson's disease (PD) has increased the need for early identification of persons at risk. Although considered controversial, some prior studies indicate that PD patients may have premorbid histories of greater trait introversion or shyness as well as increased rates of disorders associated with shyness (e.g., anxiety, affective disorders, and irritable bowel syndrome). Essential features of trait shyness include (a) inhibited and avoidant behaviors and (b) physiological hyperreactivity to the novel or unfamiliar. In parallel, (a) depression in PD patients is associated with increased harm avoidance (a possible serotonergic function), and (b) PD patients have premorbid and comorbid decreases in novelty-seeking (a possible dopaminergic function). Taken together, previous research suggests the following hypotheses: (1) given evidence for marked heritability of shyness, shy elderly should report higher rates of PD in their family members than would nonshy elderly; and (2) shy elderly without PD should exhibit psychological and biologic characteristics similar to those reported in PD. Two groups, representing the top 27% (n = 37) and bottom 31% (n = 43) of scores on a standardized shyness scale, were drawn from a larger cohort of 138 older adults (ages 50-90) living in an active retirement community. Seventeen percent of the shy versus 2% of the nonshy reported PD in a family member or self (P < .05). Shy elderly were significantly more anxious (P < .01) and depressed (P < .05) than were the nonshy.(ABSTRACT TRUNCATED AT 250 WORDS)

Identity, self, and personality: II. Glimpses through the autophotographic eye.

Subjects were 201 college students, who used R. C. Ziller's (1990) autophotographic method to answer the question who are you? Richness of self-depiction (i.e., creative and self-expressive vs. prosaic photo essays) and interpersonal connectedness of the self were examined. As expected, Openness to Experience from the 5-factor model predicted richness of photo essays. Among women, Neuroticism and Introversion also predicted richness. As expected, Extraversion and Agreeableness related to interpersonal orientations in photo essays. Intergenerational photos had especially salient meaning for personality. Three other predictions received support, bearing on such identity-relevant categories as alcohol use, religiosity, self-exhibition in bathing attire, and identification with one's school. Results are integrated with literature on interpersonal connectedness and the relation of creativity to personality.

Personality traits as predictors of anxiety prior to caesarean section under regional anaesthesia.

One hundred and fifteen patients scheduled for elective Caesarean section under regional anaesthesia were questioned to determine their personality profiles and anxiety state. Positive correlations were found between neuroticism and anxiety scores (p < 0.05). Patients with tendencies towards both neuroticism and introversion had higher pre-operative anxiety scores than other personality types (p = 0.015). In general, previous experience did not reduce pre-operative anxiety and personality appeared to be a better predictor of anxiety prior to Caesarean section under regional anaesthesia. Some personality types might benefit from additional support to improve their ability to cope with this stressful event.

A comparison of personality types among female student health professionals.

The purpose of the study reported here was to focus on the personality traits of six groups of women students in medicine, pharmacy, medical technology, physical therapy, dietetics, and occupational therapy. The Myers-Briggs Type Indicator was administered to all groups to measure Extroversion-Introversion, Sensing-Intuition, Thinking-Feeling, and Judging-Perception. Results show that (a) medical students in contrast to the other five groups are guided more by thinking than feelings in their approach to work and people and (b) pharmacy students prefer well-planned, routine work in contrast to occupational therapy students who like changing situations and flexibility. Some implications of these findings for the health team are mentioned.

Psychobehavioral and immunological characteristics of adult people with chronic fatigue and patients with chronic fatigue syndrome.

The psychobehavioral responses and cellular immune function were investigated in healthy people (control, N = 21), adult people with chronic fatigue (fatigue-non-CFS group, N = 24), and patients with chronic fatigue syndrome (CFS, N = 10). Based on psychobehavioral responses, the fatigue-non-CFS group had low general activity levels (p < .05) and slightly depressive tendencies (p < .01) compared with the control. They had many life event stresses (p < .05) and sleep disturbances (p < .01), and they could not cope appropriately with stresses. The fatigue-non-CFS group also showed significantly lower natural killer (NK) cell activity (p < .01) and decreased numbers of CD16+ and CD56+ cells (p < .05). Compared with the fatigue-non-CFS group, patients with CFS had higher degrees of physical fatigue (p < .01) and more life event stresses (p < .05). They had lower general activity levels and social introversion. They were also in a depressive state. NK cell activity and the numbers of CD16+ and CD56+ cells were significantly reduced in patients with CFS (p < .01). These findings suggest that adult people with chronic fatigue may be in an intermediate state between the healthy control and patients with CFS in terms of psychobehavioral responses and low NK cell activity. We observed three cases in such an intermediate state in whom CFS subsequently developed.

[Experience with the Lüscher test in psychiatry (author's transl)].

A population of schizophrenic patients was compared with a control group by means of the 8 color test. The schizophrenics showed a depressive factor in the preference for brown and the rejection of yellow. Interchange of gray and black suggests destructive tendencies and lack of orientation in the schizophrenic psyche. Shifts of primary colors are interpreted as signs of introversion caused by the disease. In the gray test, which gives pointers to the existential situation, healthy subjects, schizophrenics, addicts and depressives were compared with each other. While depressives and schizophrenics showed a disordered contact with the environment which is compensated by screening off the environment increasingly, the schizophrenic test sample showed destructive tendencies and signs of loss of a sense of distance in addition to the disordered contact with the environment.

A comparison of the analgesic effects of methoxyflurane-nitrous oxide and nitrous oxide alone during labour related to the Eysenck personality inventory test.

One hundred and thirty-three paturients who had received either methoxyflurane-nitrous oxide or nitrous oxide analgesia with or without pudendal block, underwent the Eysenck Personality Inventory Test on the second postpartum day and evaluated their memory of the pain (Subjectively Evaluated Pain Suffering Scores) during labor. Parturients who had received methoxyflurance-nitrous oxide analgesia reported significantly lower pain suffering than parturients who had had nitrous oxide analgesia. Subdivision according to Personality Inventory factors showed that at the introvert end of the Extroversion-Introversion scale, methoxyflurance-nitrous oxide analgesia with or without additional pudendal block resulted in significantly lower pain suffering than did not nitrous oxide analgesia. On the other hand, nitrous oxide analgesia without additional pudendal block gave significantly lower pain suffering at the extrovert end of the scale. Among the extroverts there was a tendency, though not statistically significant, towards non-approval of the pudendal block.

[Psychosomatic sterility. Search for a hypothesis for personaity structure using Moretti's graphology method].

Over the past three years the authors have performed a random clinical study on couples who came to the aim of identifying the possible presence, in those cases in which it was not possible to pinpoint an organic or functional etiological factor, of a relationship between personality structure and so-called "sterility sine cause" which according to the recent studies by Pancheri and Zichella on reproductive emotionality, is thought to caused by a factor of psychosomatic origin, The substantiality of the concept of reproductive emotionality, otherwise referred to as sexual instinct, was put forward in 1962 by Padre Gerolamo Moretti, a leading figure of Italian graphology. Research to date, carried out using traditional methods of clinical psychology, interview and tests, in an attempt to determine a particular personality profile, has not produced completely satisfactory results. From the literature it does not appear that graphological analysis has been applied in research of this nature. Graphology, if used by competent and appropriately trained persons, is certainly a powerful and refined diagnostic method which enables an idiographic, holistic and integrated personality profile (intelligence and temperament) tp be obtained for the subject in question. Moretti's temperament classification was used to define the personality structure of patients: assault, resistance, assignment and expectation. Research using graphological techniques has revealed that it is possible to define a personality structure within which suspected "sine cause" patients may be classified. In comparison to the control group, there was a prevalent attitude expressing a tendency to reserve, introversion, diffidence, anxiety, excessive and sometimes unmotivated concern regarding persons and things, attachment to one's own ideas, inflexibility of one's own position, scarce capacity to make oneself available, excessive attention to formal aspects. A number of practical considerations also emerged from the research: the good level of acceptance and compliance with the diagnostic instrument used and the fact that the patient in question does not necessarily have to be present. Due to the ease of obtaining an example of the patient's handwriting, graphological analysis could be outinely requested as the first approach in suspected cases of sterility due to psychosomatic causes.

Examining the utility of a temperament model for modelling non-melancholic depression.

OBJECTIVE: Depression is currently modelled dimensionally, along severity, duration and recurrency dimensions. An alternative model allows dimensional expressions of temperament and personality to influence risk to onset as well as persistence. Here, we examine the utility of a temperament model. METHOD: A questionnaire assessing temperament dimensions and a number of depression variables was administered to a large routine general practice sample and with the temperament measure also completed by a small clinical sample. RESULTS: 'Anxious worrying' and 'irritable' dimensions were identified as internalizing and externalizing expressions of a trait anxiety dimension, three other 'temperament' dimensions (i.e. 'introversion', 'self-centred' and 'obsessive') were refined, while a 'self-blame' dimension intruded into the factor analytic solution. High scores on the 'anxious worrying' dimension were associated with all depression parameters. The 'irritable', 'introversion' and 'self-blame' dimensions were less clearly linked with depression variables, while higher scores on the 'self-centred' and 'obsessional' dimensions did not appear to increase the chance of depression onset, persistence or recourse to treatment. CONCLUSION: A temperament-based approach appears to have some conceptual utility in modelling depression, and particularly, the non-melancholic disorders. It is likely, however, to require complementing with refined at-risk personality dimensions.

[Natural science basis of individuality].

Results of experiments on animals with ablation of different parts of the brain and analysis of published data suggest that the neurophysiological basis of temperaments, according to Hippocrates, of nervous system types, according to Pavlov, and of extra-introversion consists in individual peculiarities of interaction of four structures: the frontal neocortex, the hippocampus, the amygdala and the hypothalamus. Pathological disturbance of this interaction produces the basic varieties of neuroses: hysteria, neurasthenia, psychasthenia and obsessive states. The significance is discussed of individual features of sets and hierarchy of basal human needs: material-biological, social, ideal (with their variants: retention and development, "for oneself" and "for others") needs of overcoming (will) and of "fitness" - for the formation of individuality.

Personality traits and cognitive styles as risk factors for serious suicide attempts among young people.

The contribution of a series of measures of personality and/or cognitive style to serious suicide attempt risk in young people was examined in a case-control study. Individuals making suicide attempts had elevated odds of hopelessness, neuroticism, introversion, low self-esteem, impulsiveness, and external locus of control. When allowance was made for intercorrelations between these measures, hopelessness, neuroticism, and external locus of control remained significant risk factors for serious suicide attempt; self-esteem, extraversion, and impulsiveness were not significantly associated with suicide attempt risk. Nonsignificant findings were explained by the presence of substantial correlations between these measures and measures of hopelessness, neuroticism, and external locus of control.

[Parameters of the spatial of organization of EEG in persons with various individual characteristics].

The relationships between some characteristics of EEG topographic maps and personality traits (extraversion-introversion, sensation-intuition, thinking-feeling, judging-impulsiveness) by the Keirsey's Type Inventory were studied in 46 17-20-year-old men). The most considerable distinctions in the spatial organization of the EEG were observed between the functions sensation and intuition. The high-sensation responders were characterized by higher EEG power in the theta 1, 2 and alpha 1-bands in all derivations and higher coherence (especially in the theta 1, 2 bands most expressed in the frontoparietal areas) as compared with the high-intuition responders. The expression of extraversion was positively correlated with coherence values in the theta 1, 2 and negatively correlated with coherence in the alpha 1, 2 bands. Characteristic EEG patterns for other types of personality traits were also described. The results suggest that some characteristics of brain maps reflect the individual psychological features determined on the basis of Jung's typology.

Chronic tension-type headache in school-aged children--personality traits and behavior.

Basic personality traits and specific behavior characteristics were assess in 39 patients (12 to 15 years old) having chronic tension-type headache. Patients were referred for clinical examination to the Neural-pediatrics Ward of the Department of Pediatrics, Osijek, Croatia. Eysenck Personality Questionnaire--Juniors (EPQ-J), a new Croatian personality Questionnaire of domination, aggression, introversion and ambition (DAIA), were applied for the testing. The scores obtained by patients in personality questionnaires were compared with averages scores normal sample of healthy pupil same ages. Our patients were found to have no signs of emotional instability. Their behavior is prosocial, nonaggressive, and ambitious, aimed at the achievement of superior results at school and life although already quite successful in their studies. Tensions arising from the school setting seem to be important factors triggering tension-type headaches.

The relationship of male transsexual typology to psychosocial adjustment.

In a search to uncover variables predictive of psychosocial adjustment of male transsexuals, this study examined features which have been empirically linked to characteristics of male transsexual typology. Data from 25 male transsexual volunteers were examined by means of multiple regression analysis to determine whether symptoms of introversion, depression, or tension, as well as adjustment to work and gender reorientation could be linked to the typological variables of androphilia, gynephilia, cross-gender fetishism, feminine gender identity in childhood, and age of onset of transsexualism. Valid and reliable scales measuring the typological variables of erotic partner preference (androphilia and gynephilia), cross-gender fantasy in association with sexual arousal (cross-gender fetishism), and degree of feminine gender identity in childhood were used. Results indicate a significant relationship between social gender reorientation and the feature of androphilia and between work adjustment and gynephilia. This differential adaptation is explained in terms of the different course that transsexualism takes within each typological subgroup. These findings offer evidence as to why some transsexuals may more readily adopt a female gender identity than others. There was no relationship found between the typological features and those variables measuring psychological disturbance.
