OBJECTIVE To explore the psychometric characteristics of a modified version of the Cloninger's personality questionnaire, the Temperament and Character Inventory-Revised (TCI-R). METHOD A 482-subject sample, including clinical and non-clinical subjects, completed the TCI-R. We performed principal component analyses and explored the factorial structure of(More)
OBJECTIVE The authors describe personality development and disorders in relation to symptoms of attention deficit hyperactivity disorder (ADHD) and autism spectrum disorders. METHOD Consecutive adults referred for neuropsychiatric investigation (N=240) were assessed for current and lifetime ADHD and autism spectrum disorders and completed the Temperament(More)
The Temperament and Character Inventory (TCI; Cloninger, Przybeck, Svrakic, & Wetzel, 1994) is a self-questionnaire developed to assess the 7 dimensions of personality described by Cloninger et al. (1994) with a total of 29 subscales. In 1999, a revised version was proposed by Cloninger (TCI-R). In this study, we present psychometric properties of the TCI-R(More)
INTRODUCTION The revised version of the Temperament and Character Inventory (TCI-R), a tool designed by C. R. Cloninger for the evaluation of the seven dimensions defined in his psychobiological model of personality, was translated and adapted to Spanish. The aim of the study was to obtain normative data and scales with T-scores in a incidental sample of(More)
BACKGROUND The objective of this study was to compare personality traits between major depressive disorder (MDD) patients and healthy comparison subjects (HC) and examine if personality traits in patients are associated with specific clinical characteristics of the disorder. METHODS Sixty MDD patients (45 depressed, 15 remitted) were compared to 60 HC(More)
BACKGROUND Quantitative endophenotypes are needed to better understand the pathogenesis of schizophrenia. The psychobiological model of temperament and character suggests that personality traits are heritable and regulated by brain systems influencing schizophrenia susceptibility. Thus, measures of temperament and character may serve as(More)

It was designed to measure the character and temperament dimensions of Cloninger's model of personality using a true-false response format. The revised TCI (TCI-R) uses a five-point-Likert format and has multiple subscales for persistence to improve its reliability. We(More)

In this present study, we examined the relationship between the Cloninger's dimensional psychobiologic model of personality and depression in an outpatient population with major depressive disorder. Eighty-one depressed outpatients (67 women, 14 men) and 51 healthy controls (35 women, 16 men) filled out the Turkish version of the Temperament and Character(More)
BACKGROUND AND METHODS In vivo neuroimaging studies have provided evidence of decreases in the gray matter volume of the cingulate gyrus in subjects with schizophrenia as compared to healthy controls. To investigate whether these changes might be related to heritable influences, we used high-resolution magnetic resonance imaging and labeled cortical mantle(More)
