Local cerebral uptake of deoxyglucose labeled with fluorine 18 was measured by positron-emission tomography in eight patients with schizophrenia who were not receiving medication and in six age-matched normal volunteers. Subjects sat in an acoustically treated, darkened room with eyes closed after injection of 3 to 5 mCi of deoxyglucose 18F. After uptake,(More)
BACKGROUND The relationship between alexithymia and dissociation is not known. Both mechanisms ward off overwhelming affective states; hence, this report examines the relationship between dissociation, alexithymia, depressed mood and the five-factor model of personality in a sample of psychiatric outpatients. METHODS One hundred and sixteen outpatients(More)
This study explores the contribution of parental qualities to the borderline personality disorder. The Parental Bonding Inventory is used to compare four parental qualities (caring mother, caring father, overprotective father, and overprotective mother) across three groups (borderline personality disorders, assorted psychiatric controls and normal(More)
A total of 62 staff members from a general hospital participated in a study about alexithymia and the five-factor model of personality, measured by the Toronto Alexithymia Scale and the NEO Five Factor Inventory, respectively, and their relationship to recognition affect. Subjects with alexithymic characteristics were less able to recognize affective states(More)
Cortical atrophy measured with computed tomography was observed in ten of 53 schizophrenic patients. Levels of homovanillic acid, dihydroxyphenyl acetic acid (DOPAC), conjugated DOPAC, and dopamine sulfate (DASO4) were measured in the cerebrospinal fluid of these patients during a drug-free evaluation. Patients with cortical atrophy had lower cerebrospinal(More)
Alexithymia is described as both a primary personality trait and a secondary state reaction to medical illness. To empirically study secondary alexithymia, a series of medically ill patients seen in psychiatric consultation were compared with a healthy control population. Measured by the Toronto Alexithymia Scale (TAS), the medically ill were more(More)
Computed tomographic (CT) scans of 28 chronic schizophrenic patients, 15 chronic schizoaffective patients, and 19 patients with bipolar affective disorder were compared on three measures: ventricular size, sulcal prominence (cortical atrophy), and cerebellar atrophy. Because the patients with bipolar disorder were older, measures were adjusted by(More)
The relationship between depressed mood and alexithymia, measured by the Toronto Alexithymia Scale (TAS) was investigated in a group of psychiatric inpatients (n = 81) and outpatients (n = 97). In both cohorts correlations between the TAS and obsessoid personality style were significant when controlled for mood. The obsessoid style, measured by the(More)
This paper investigates how the creativity of individual team members is related to team creativity, and the influence of climate for creativity in the workplace on individual and team creativity. A multilevel theoretical model is proposed, and the authors report a study which tests the model using a sample of 54 research and development teams. The results(More)
The relationship between alexithymia assessed by the Toronto Alexithymia Scale (TAS) and the five-factor model of personality measured by the NEO Five-Factor Inventory (FFI) was investigated in a group of psychiatric outpatients (n = 114) and normal volunteers (n = 71). When controlling for depression, the domains of neuroticism, introversion, and low(More)
