[Influence of radioactive pollution on the character of the distribution of wild mouselike rodents according to the measure of lipid antioxidant activity in their organs].

The estimation of the degree of the radioactive contamination effect on the antioxidative status in tissues of rodents from natural populations is done by means of biometric methods. It is shown, that the character of distribution and variability of the lipids antioxidant activity (AOA) differs significantly depending of species and age of animals, the degree of contamination on areas where wild rodents were caught and time during which the radioactive factor affected. The change in character of the animals distribution in AOA of the brain lipids for the more radioresistant Clethrionomys glareolus Schreb, occurs the later than for the more radiosensitive Apodemus agrarius and especially for Microtus oeconomus Pall. The data obtained make possible to suppose, that the long-term effect of the low intensive ionizing radiation results the qualitative changes in the rodents natural populations state.

Differential diagnosis of personality disorders by the seven-factor model of temperament and character.

We used multiaxial structured interviews and questionnaires to evaluate the ability of self-reports on seven personality dimensions to predict independent interview diagnoses of DSM-III-R personality disorders. We studied 136 consecutive adult psychiatric inpatients, excluding those with psychosis, organic mental disorders, and severe agitation. Sixty-six patients had interview diagnoses of DSM-III-R personality disorders. Most also had mood disorders. We confirmed the hypotheses that self-reports of low self-directedness and cooperativeness strongly predicted the number of personality symptoms in all interview categories, whereas the other factors distinguished among subtypes as predicted. Self-directedness and cooperativeness also predicted the presence of any personality disorder by differentiating patients varying in risk from 11% to 94%. Patients in clusters A, B, and C were differentiated by low reward dependence, high novelty seeking, and high harm avoidance, respectively. We conclude that low self-directedness and cooperativeness are core features of all personality disorders and are validly measured by the seven-factor Temperament and Character Inventory, but not the five-factor Neuroticism-Extraversion-Openness inventory. Each DSM-III-R personality disorder category is associated with a unique profile of scores in the seven-factor model, providing an efficient guide to differential diagnosis and treatment.

A sib-pair study of the Temperament and Character Inventory scales in major depression.

BACKGROUND: Certain aspects of the personality may be associated with the vulnerability to develop depression. A sib-pair method has been used to examine the familiality of the 7 scales of the Temperament and Character Inventory (TCI) and whether this could be related to the genetic vulnerability to develop depression. METHODS: Probands with depression and their nearest-aged siblings from Wales were compared with healthy control probands and their nearest-aged siblings on the TCI and measures of depressed mood. RESULTS: All 7 scales of the TCI were familial, and scores on 6 of the scales were similar to US population scores. However, the Welsh subjects' scores on the self-transcendence scale were markedly lower than the US mean, suggesting strong cultural or national influences on this measure. Harm avoidance scores were substantially influenced by current and past depression, but this scale also showed stable traitlike characteristics that are likely related to the genetic vulnerability to depression. Novelty seeking and self-directedness were also partly state-dependent and were negatively correlated with low mood; high scorers may be resilient to the development of depression. High reward dependence may also protect against the development of depression and is unrelated to mood state. The cooperativeness, persistence, and self-transcendence scales appear to have a limited relationship with the development of depression. CONCLUSIONS: Harm avoidance, reward dependence, novelty seeking, and self-directedness have traitlike characteristics that are related to the familiality of depression. Cooperativeness, self-transcendence, and persistence are also familial, but this appears to be unrelated to depression.

Basic character inventory personality traits among patients with major depression, anxiety disorders and mixed conditions.

Two hundred and seventy-two mainly nonpsychotic psychiatric outpatients between 19 and 59 years of age were divided into various clinical groups according to DSM-III: pure major depression, major depression in combination with various anxiety disorders, pure anxiety disorders and a group with other mental disorders. The groups were compared as to differences in personality traits assessed by means of the Basic Character Inventory. The mixed major depression/non-panic anxiety disorder group appeared to be the most deviant with more oral-neurotic personality traits in addition to obsessive traits, while the pure major depressive disorder and the pure anxiety disorder group were less disturbed. Especially cases with non-panic-anxiety features in addition to major depression were those which manifested a neurotic obsessive personality structure. These findings imply that it is important to distinguish between major depression cases with and without various anxiety disorders.

Personality in patients with migraine evaluated with the "Temperament and Character Inventory".

The objective of this study was to assess the personality profile of a sample of Mexican patients with migraine using the Temperament and Character Inventory (TCI). A cross-sectional study was performed including adult migraine patients identified from the outpatient neurology clinics of two large teaching hospitals in Mexico City. Patients were asked to voluntarily participate in the study. A physician conducted a standardised diagnostic interview adhering to the criteria of the International Headache Society (IHS). Patients were interviewed and administered the TCI. We used two healthy controls groups and a third group of non-migraine pain controls. One hundred and fortytwo subjects with migraine, 108 healthy blood donors, 269 young healthy controls and 30 patients with non-migraine pain (NMP) were included in the study. Patients with migraine had higher scores in the dimension harm avoidance (HA) and all its sub-dimensions (p<0.05) than healthy patients. Patients with non-migraine pain had high scores in HA and low scores in novelty seeking, self-directedness and cooperativeness. Blood donors had high scores in the following subdimensions: HA1, HA4 and C3 (Cooperativeness). Personality features consistent with migraine are avoidance, rigidity, reserve and obsessivity. Our study shows that patients with chronic pain share some of the personality features of patients with migraine but their TCI profile could be indicative of cluster C avoidant personality. Blood donors were shown to have more energy, with a tendency to help other people and be more optimistic. The results support serotoninergic involvement as explaining the physiopathology of migraine.

Responsible engineering: the importance of character and imagination.

Engineering Ethics literature tends to emphasize wrongdoing, its avoidance, or its prevention. It also tends to focus on identifiable events, especially those that involve unfortunate, sometimes disastrous consequences. This paper shifts attention to the positive in engineering practice; and, as a result, the need for addressing questions of character and imagination becomes apparent.

Dexamethasone suppression test and TRH-TSH test in subaffective dysthymia and character-spectrum disorder.

Based on Akiskal's criteria of subaffective dysthymia (SDT) and character-spectrum disorder (CSD) as the two, etiologically distinct forms of early-onset primary dysthymia, the authors investigated the dexamethasone suppression test (DST) in 18 patients with SDT and in 30 patients with CSD. TRH-TSH test was also investigated in smaller subsamples of the patients (n = 8, and n = 7, respectively). Fifty percent of the patients with SDT showed abnormal DST and TRH-TSH test results respectively, while the figures in the CSD patients were 7% and 0%. These findings suggest that SDT is a clinically diagnosable and biologically distinct subgroup within the broader category of early-onset primary dysthymia, which represents a symptomatically milder version of primary affective disorder.

Exploring the link between character, personality disorder, and neuropsychological function.

Personality deviations and deficits in cognitive executive function are common among forensic populations. The present study on incarcerated offenders explored whether there are links between the two domains. Personality was assessed using the Temperament and Character Inventory (TCI). Neuropsychological performance, including visual working memory, attentional set-shifting and planning, were tested with the Cambridge Neuropsychological Test Automated Battery (CANTAB). Subjects with personality disorders scored high on harm avoidance, and low on self-directedness and cooperativeness. Personality disordered offenders did not differ from the comparison groups (offenders without personality disorder, and non-criminal controls) with regard to CANTAB measures of visual working memory (delayed matching to sample, spatial working memory) and planning (Stockings of Cambridge), but they made a larger number of errors on the attentional set-shifting task. Dimensional analysis of the personality and neuropsychological variables revealed significant associations between self-directedness and cooperativeness on the one hand, and attentional set-shifting on the other. Intellectually disabled, non-criminal individuals (marginal mental retardation) who performed poorly on attentional set-shifting also scored low on self-directedness and cooperativeness. The results indicate that poor development of certain personality traits may be associated with deficits in neuropsychological functioning.

The influence of temperament and character on functioning and aspects of psychological health among people with schizophrenia.

Research findings that link personality factors to functioning and symptoms in schizophrenia are inconsistent, and further studies are needed within the area. The purpose of this study was to investigate how personality, as measured by the Temperament and Character Inventory (TCI), was related to demographic factors, subtypes of diagnoses, level of functioning, and aspects of psychological health, including sense of coherence, perceived control, and self-esteem, among people with schizophrenia. Subjects were 104 individuals, aged 20-55 years, in psychiatric outpatient care. The results indicated that personality was not related to subtypes of diagnoses or demographic characteristics of the respondents, but to level of functioning and all aspects of psychological health. Especially self-directedness distinguished three groups of functioning and was highly correlated with the different aspects of psychological health. The article discusses how knowledge of schizophrenic patients' personality structure might be used for tailoring psychiatric treatments.

Temperament and character inventory (TCI) personality profile in metamphetamine abusers: a controlled study.

We applied the temperament and character inventory (TCI) personality questionnaire in 41 inpatients dependent on metamphetamine, and 35 controls. Novelty seeking, harm avoidance and self-transcendence were significantly higher, and persistence, self-directedness and cooperativeness were significantly lower in the patients than in the healthy volunteers. The detected differences may be important for prevention and treatment.

Adolescent attachment styles and their relation to the temperament and character traits of personality in a general population.

Attachment styles as well as personality traits in adolescents and adults have been found to be associated with their health outcomes and with their personality pathology. In this cross-sectional exploratory study, we study the relationship between attachment styles that derive from our data employing the items of Feeney et al. (1994) self-report attachment style questionnaire (ASQ), and personality traits given by the junior version of Cloninger et al. (1993) self-report temperament and character inventory (TCI), in a sample of 426 adolescents (54% females) from a general population. The secure attachment style was correlated significantly negatively with the personality trait harm avoidance (HA), but significantly positively with the personality traits novelty seeking (NS), reward dependence (RD), cooperativeness (CO) and self-transcendence (ST). The preoccupied (anxious/ambivalent) attachment style was correlated significantly positively with HA and NS, but significantly negatively with self-directedness (SD). The fearful-avoidant category was correlated significantly negatively with NS. Our five-factor solution of the attachment styles and their relation to the TCI point towards a need for a modification of the two-axis, four-category attachment model of Bartholomew (1990) and Bartholomew and Horowitz (1991), with their category dismissing-avoidant replaced by the two categories defined here as dismissing relations (correlated significantly negatively with CO) and dismissing others (correlated significantly negatively with RD and significantly positively with SD).

The temperament and character inventory in major depression.

Patients admitted for pharmacological treatment of a non-bipolar major depressive episode completed the Temperament and Character Inventory (TCI) prior to and after at least 6 weeks of treatment. Treatment with various antidepressants resulted in a 43% reduction of symptomatology. Scores on the harm avoidance dimension before and after treatment appeared to be significantly higher as compared to Dutch normative data. TCI scores did not predict response to treatment or show a change during treatment. It is concluded that, in this group of patients, the personality dimension harm avoidance is a trait factor without predictive value for antidepressant responsiveness.

Visual P300 and the self-directedness scale of the Temperament and Character Inventory.

Reduced amplitude of the P300 event-related brain potential has been associated with several psychopathological conditions and is thought to represent brain dysfunction in such conditions. Predisposition to personality disorders and psychopathology in general is also associated with low scores on the self-directedness (SD) scale of the Temperament and Character Inventory. The present preliminary study investigated the relationship between amplitudes of P300 elicited by rare target stimuli in a visual oddball task and SD scores in 58 healthy participants. P300 was found to be significantly reduced in subjects with low SD, as supported by correlational analysis and by comparison of groups formed on the basis of SD scores. This finding may be relevant to prior findings indicating reduced P300 amplitudes in a variety of psychopathological conditions and suggests that a common vulnerability factor, reflected in the low SD personality scores, may contribute to the P300 reduction in psychiatric populations.

Test-retest reliability of the Temperament and Character Inventory in patients with opiate dependence.

We examined the test-retest reliability of the Temperament and Character Inventory (TCI) in a clinical sample of 29 inpatients with opiate dependence disorder (DSM-IV). The previously validated French translation of the TCI was administered at baseline and again four weeks later. Intraclass correlation coefficients (ICCs) were used to estimate stability of the TCI over time for the 15 patients who completed the study. For all ICCs, the TCI showed satisfactory to excellent stability across all factors (ICC= 0.66-0.82). Stability was lower for the two temperamental traits of 'persistence' (ICC=0.51) and 'reward dependence' (ICC=0.63), possibly reflecting both clinical instability and measurement errors. These results highlighted the overall stability of the TCI in patients with opiate dependence and provided evidence for the usefulness of this questionnaire, which was originally designed to explore genetic and environmental factors underlying normal and abnormal personality dimensions. Further studies are required to confirm these results on larger clinical samples.

[Temperament and character profiles of female adolescent patients with anorexia and bulimia nervosa].

OBJECTIVE: Based on the personality model outlined by Robert C. Cloninger, studies in adult patient samples demonstrated that according to distinct personality profiles patients with anorexia nervosa could be differentiated from those with bulimia nervosa, as well as from healthy controls. The current study examines whether these personality-related differences also exist in adolescent patients with eating disorders and a short duration of illness. METHOD: The sample studied consists of 73 consecutively admitted female patients aged 12 to 18 years, with eating disorders. The German version of the Junior Temperament and Character Inventory (JTCI) was administered to 29 patients with anorexia nervosa, restricting type (AN-R), to 16 patients with anorexia nervosa, binge-eating/purging type (AN-B), and to 28 patients with bulimia nervosa (BN). RESULTS: Different temperamental factors were most pronounced between AN-R and BN patients, whereas AN-B patients exhibited a personality profile between those of AN-R and BN. BN patients scored higher on Novelty Seeking but lower on Persistence than AN-R patients. In contrast to AN-R patients, both BN and AN-B patients scored lower on Self-Directedness. CONCLUSIONS: The current results of differential temperamental dimensions in adolescent patients with eating disorders tended to be similar to findings for adult patients, which strengthens the assumption that distinct personality factors underlie the different subtypes of eating disorders.

Personality traits of anaesthetists and physicians: an evaluation using the Cloninger Temperament and Character Inventory (TCI-125).

The personality profiles of Specialist Anaesthetists, Trainee Anaesthetists and Specialist Physicians were examined using Cloninger's Temperament and Character Inventory. These were compared with validated Community Sample 'average values' and a historical Norwegian Physician sample. Completed forms were returned from 364 doctors (Specialist Anaesthetists 222, Trainee Anaesthetists 75, Physicians 67), an overall response rate of 71%. Specialist Anaesthetists were more Cooperative, Harm Avoidant and Self-Directed than the Community Sample but less Reward Dependent, Novelty Seeking and Persistent than the Community Sample. Physicians were more Cooperative than their Specialist Anaesthetist colleagues, but both more so than were the general population. Trainee anaesthetists appear to be more Novelty Seeking and Reward Dependent than the Specialist Anaesthetists, this factor being predominately age related. Extreme/Mild personality traits were identified in 33% of Specialists, 41% of Trainees and 33% of Physicians, whilst personality disorders were found at the expected rates (Specialist Anaesthetists 9%, Trainee Anaesthetists 10%, Physicians 2%). Personality assessment has implications for recruitment, crisis management and professional development within anaesthesia.

Adult-type metachromatic leukodystrophy with a compound heterozygote mutation showing character change and dementia.

A 26-year-old Japanese woman slowly developed a change of character such as hypospontaneity and blunted affect, followed by obvious mental deterioration. She was diagnosed as having a disorganized type of schizophrenia at the first examination. Brain magnetic resonance imaging demonstrated diffuse high intensity in the cerebral white matter, particularly in the frontal lobes. The single photon emission computed tomography images using 123I-IMP disclosed diffuse cerebral hypofusion, especially in the frontal lobes. Electroencephalogram showed a moderate amount of 5-6Hz theta waves on the background of alpha activity. Nerve conduction velocities in the extremities were delayed. The level of leucocyte arylsulphatase was low. In the arylsulphatase A gene analysis, a compound heterozygote having the 99Gly-->Asp and 409Thr-->Ile mutations was confirmed. The patient was diagnosed as having metachromatic leukodystrophy. She gradually showed obvious dementing symptoms such as memory disturbance and disorientation. The characteristics of the psychiatric symptoms in the leukodystrophy are discussed.

Borderline personality disorder in major depression: symptomatology, temperament, character, differential drug response, and 6-month outcome.

Among 183 depressed patients participating in a randomized long-term treatment trial of fluoxetine and nortriptyline, 30 patients had borderline personality disorder (BPD), 53 had other personality disorders (OPD), and 100 had no personality disorders (NPD). The borderline depressed patients had earlier age of onset of their depressions, more chronic depressions, more alcohol and cannabis comorbidity, and were more likely to have histories of suicide attempts and of self-mutilation. On self-report, patients with BPD and OPD reported more phobic symptoms, greater interpersonal sensitivity, and more paranoid ideation. Uniquely, BPD patients were more angry than OPD patients. BPD patients had high novelty seeking, high harm avoidance, low self-directedness, and low cooperativeness. Depressed patients with BPD did poorly in the short term if treated with nortriptyline rather than fluoxetine. After 6 months, those with BPD had a favorable outcome in regard to depressive symptoms, social adjustment, and even improvement in the character measure of self-directedness. Those with the poorest outcome were those with OPD.
