RESUMO
Objective: The mind-brain problem (MBP) has marked implications for psychiatry, but has been poorly discussed in the psychiatric literature. This paper evaluates the presentation of the MBP in the three leading general psychiatry journals during the last 20 years. Methods: Systematic review of articles on the MBP published in the three general psychiatry journals with the highest impact factor from 1995 to 2015. The content of these articles was analyzed and discussed in the light of contemporary debates on the MBP. Results: Twenty-three papers, usually written by prestigious authors, explicitly discussed the MBP and received many citations (mean = 130). The two main categories were critiques of dualism and defenses of physicalism (mind as a brain product). These papers revealed several misrepresentations of theoretical positions and lacked relevant contemporary literature. Without further discussion or evidence, they presented the MBP as solved, dualism as an old-fashioned or superstitious idea, and physicalism as the only rational and empirically confirmed option. Conclusion: The MBP has not been properly presented and discussed in the three leading psychiatric journals in the last 20 years. The few articles on the topic have been highly cited, but reveal misrepresentations and lack of careful philosophical discussion, as well as a strong bias against dualism and toward a materialist/physicalist approach to psychiatry.

There is a high prevalence of psychotic-like experiences in nonclinical patient cohorts from Brazil. This study aimed to test whether personality dimensions, as well as schizotypy, are important predictors of quality of life (QoL) in individuals with psychotic experiences (PE). METHOD: 115 participants were recruited from Spiritist Centers in Brazil. At the 1-year follow up, 90 participants (78%) were reassessed. Instruments were the SCID-I (Structured Clinical Interview for DSM-IV), TCI-R 140 (Revised Temperament and Character Inventory), OLIFE-R (Oxford-Liverpool Inventory of Feelings and Experiences), and WHOQOL-BREF (World Health Organization QoL Instrument). RESULTS: Mean age (±SD) was 36.8 (±12.5) years; 70% were female. Participants reported 74.4% of PE at time 1 and 72.3% at time 2. At time 1, temperament and character explained 47% of the psychological QoL variance; self-directedness was the strongest predictor of higher QoL, while harm avoidance and introverted anhedonia predicted worse QoL. At the 1-year follow-up, self-directedness remained the most important predictor of psychological QoL. CONCLUSION: Individuals reporting PE can show psychological QoL when they are high on self-directedness. Those with high levels of introverted anhedonia and cognitive disorganization can have a lower QoL and may be at risk for mental health problems.

BACKGROUND: The Temperament and Character Inventory (TCI) was first described in 1993. 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 tested the clinical validity of an original Brazilian-Portuguese translation of the TCI-R. METHODS: The 595 volunteers completed the BrP version of TCI-R, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Satisfaction with Life Scale (SWLS). RESULTS: The internal consistency was satisfactory for all dimensions (Cronbach alpha coefficients above 0.7). The cumulative variances for temperament and character were 58% and 60%. BAI was positively correlated with harm avoidance and negatively with persistence, self-directedness and cooperativeness. SWLS was correlated negatively with harm avoidance and positively with self-directedness and cooperativeness. The congruence coefficients between each facet of BrP TCI-R and the US TCI-R original data were 95% or higher (except NS1). LIMITATIONS: The main limitation of this study is the convenience sampling. CONCLUSIONS: The BrP version of the TCI-R had good psychometric properties regardless of the cultural and educational backgrounds of subjects. The present study supported the validity of the BrP translation of the TCI-R, which encourages its use in both clinical and general community samples.

OBJECTIVE: We compared temperament and character traits in children and adolescents with bipolar disorder (BP) and healthy control (HC) subjects. METHOD: Sixty nine subjects (38 BP and 31 HC), 8-17 years old, were assessed with the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime. Temperament and character traits were measured with parent and child versions of the Junior Temperament and Character Inventory. RESULTS: BP subjects scored higher on novelty seeking, harm avoidance, and fantasy subscales, and lower on reward dependence, persistence, self-directedness, and cooperativeness compared to HC (all p < 0.007), by child and parent reports. These findings were consistent in both children and adolescents. Higher parent-rated novelty seeking, lower self-directedness, and lower cooperativeness were associated with co-morbid attention-deficit/hyperactivity disorder (ADHD). Lower parent-rated reward dependence was associated with co-morbid conduct disorder, and higher child-rated persistence was associated with co-morbid anxiety. CONCLUSIONS: These findings support previous reports of differences in temperament in BP children and adolescents and may assist in a greater understating of BP children and adolescents beyond mood symptomatology.
