Translation and cross-cultural adaptation to Brazilian Portuguese of two brief screening tools for at-risk psychosis youth: the Prodromal Questionnaire (PQ-16) and the PRIME-Screen.

INTRODUCTION: Prodromal characteristics of psychosis have been described for more than a century. Over the last three decades, a variety of studies have proposed methods to prospectively identify individuals (and youth in particular) who are at high risk of developing a psychotic disorder. These studies have validated various screening instruments and made them available in several languages. Here, we describe the translation into Brazilian Portuguese and cross-cultural adaptation of two such screening tools - the Prodromal Questionnaire-16 (PQ-16) and the Prevention through Risk Identification, Management, and Education (PRIME)-Screen. METHOD: Two bilingual native speakers of Brazilian Portuguese translated the questionnaires from English. A native English speaker then performed back-translations into English. These back-translated versions were submitted to the original authors. They provided feedback and later approved the final versions. RESULTS: After translation and cross-cultural adaptation, no items needed to be changed in the adapted PQ-16 and four items were revised in the PRIME-Screen. After the peer-review process, we included two suggestions in the PQ-16 to facilitate use of the tool in our cultural and social contexts. The PRIME-Screen did not need further changes. CONCLUSION: These new instruments can help screen Brazilian Portuguese-speaking patients who are at risk of psychosis in primary care.

No Sex Difference in Mental Fatigue Effect on High-Level Runners' Aerobic Performance.

PURPOSE: Some evidence suggests that sedentary women may be more vulnerable to cognitive task-induced mental fatigue. Mental fatigue, in turn, may worse aerobic exercise performance, presumably via increased perceived effort. However, it remains unclear whether acute mental fatigue induction increases perceived effort and worsens endurance performance in high-level professional athletes and whether such effects are influenced by sex. METHODS: We studied 30 athletes (15 women and 16 men) in a single-blinded, randomized, controlled and crossover protocol. In separate visits, athletes either performed a 45-min cognitive task (Stroop's color-word conflict test) to induce mental fatigue or watched a 45-min documentary as control. Then athletes performed a time-to-exhaustion test on a treadmill. RESULTS: Perceptual measures and cognitive performance indicated that the prolonged cognitive task induced a similar mental fatigue state in women and men. Cardiorespiratory and metabolic responses to the TEE did not change with mental fatigue in both sexes. Mental fatigue increased perceived effort during the time-to-exhaustion test, anticipated attainment of maximal effort, and shortened time to exhaustion similarly in women and men (mean ± SE, -27.3 ± 20.9 s for women vs -26.7 ± 15.1 s for men; P = 0.98). CONCLUSIONS: The prolonged cognitive task provoked mental fatigue, anticipated attainment of maximal perceived effort, and worsened aerobic performance in professional runners with no sex differences. Although we did not contrasted athletes with nonathletes, our results suggest that being an athlete may somehow prevent women from developing greater mental fatigue and suffering more from its underlying effects compared with men.

Transcranial direct current stimulation (tDCS) in elderly with mild cognitive impairment: A pilot study.

Transcranial direct current stimulation (tDCS) is a non-invasive, painless and easy-to use-technology. It can be used in depression, schizophrenia and other neurological disorders. There are no studies about longer usage protocols regarding the ideal duration and weekly frequency of tDCS. OBJECTIVE: to study the use of tDCS twice a week for longer periods to improve memory in elderly with MCI. METHODS: a randomized double-blind controlled trial of anodal tDCS on cognition of 58 elderly aged over 60 years was conducted. A current of 2.0 mA was applied for 30 minutes for 10 sessions, twice a week. The anode was placed over the left dorsolateral prefrontal cortex (LDLFC). Subjects were evaluated before and after 10 sessions by the following tests: CAMCOG, Mini-Mental State Examination (MMSE), Trail Making, Semantic Verbal Fluency (Animals), Boston naming, Clock Drawing Test, Word list memory (WLMT), Direct and Indirect Digit Order (WAIS-III and WMS-III) and N-back. RESULTS: After 10 sessions of tDCS, significant group-time interactions were found for the CAMCOG - executive functioning (χ2 = 3.961, p = 0.047), CAMCOG - verbal fluency (χ2 = 3.869, p = 0.049), CAMCOG - Memory recall (χ2 = 9.749, p = 0.004), and WMLT - recall (χ2 = 7.254, p = 0.007). A decline in performance on the CAMCOG - constructional praxis (χ2 = 4.371, p = 0.037) was found in the tDCS group after intervention. No significant differences were observed between the tDCS and Sham groups for any other tasks. CONCLUSION: tDCS at 2 mA for 30 min twice a week over 5 consecutive weeks proved superior to placebo (Sham) for improving memory recall, verbal fluency and executive functioning in elderly with MCI.

A ETCC (estimulação transcraniana por corrente contínua) é uma tecnologia não-invasiva, indolor e de fácil utilização. Pode ser usada na depressão, esquizofrenia e outros distúrbios neurológicos. Não há orientações ideais sobre o uso de protocolos mais longos quanto à duração e frequência semanal da ETCC. OBJETIVO: estudar o uso de ETCC duas vezes por semana por 5 semanas em idosos com CCL. MÉTODOS: o estudo foi controlado, randomizado, duplo-cego com ETCC anódica em 58 idosos acima de 60 anos. Uma corrente de 2,0 mA foi aplicada por 30 minutos durante 10 sessões consecutivas, 2 vezes por semana. O ânodo foi colocado no córtex pré-frontal dorsolateral esquerdo (LDLFC). Os pacientes foram avaliados antes e após 10 sessões pelos testes: CAMCOG, Mini-Exame do Estado Mental (MMSE), Trilhas, Fluência Verbal Semântica - Animais, Boston, Relógio, Memória da Lista de Palavras (WLMT), Dígitos - ordem direta e indireta (WAIS-III e WMS-III) e N-back. RESULTADOS: foram encontradas interações significativas (tempo/grupo) para CAMCOG - funcionamento executivo (χ2 = 3,961, p = 0,047), CAMCOG - fluência verbal (χ2 = 3,869, p = 0,049), CAMCOG - recuperação da memória (χ2 = 9.749, p = 0,004), WMLT - recordação (χ2 = 7,254, p = 0,007). Foi observado um declínio no grupo ETCC após a intervenção para CAMCOG - praxia construtiva (χ2 = 4,371, p = 0,037). Não encontramos diferenças significativas entre os grupos ETCC e placebo para outros testes. CONCLUSÃO: A ETCC de 2 mA por 30 min, 2x por semana, por 5 semanas consecutivas, é superior ao placebo (Sham) na melhoria da recuperação de memória, fluência verbal e funcionamento executivo em idosos com CCL.

Effect of transcranial direct current stimulation (tDCS) over the prefrontal cortex combined with cognitive training for treating schizophrenia: a sham-controlled randomized clinical trial.

INTRODUCTION:: We report a transcranial direct current stimulation (tDCS) protocol over the dorsolateral prefrontal cortex (DLPFC) combined with cognitive training in schizophrenia. METHOD:: We assessed psychotic symptoms in nine patients using the Positive and Negative Syndrome Scale (PANSS). All evaluations were scored at baseline, at the end of the intervention protocol, and during a 4-week follow-up. The tDCS protocol consisted of 10 consecutive sessions over 5-day periods. We placed the cathode over the right and the anode over the left DLPFC. For sham stimulation, we turned the device off after 60 seconds. Cognitive training consisted of the administration of N-back and sequence learning tasks. RESULTS:: We performed an analysis of covariance (ANCOVA) to adjust for the dependent variable PANSS, considering the interaction with baseline severity scores (p = 0.619). Mixed analysis of variance (ANOVA) showed no statistical significance between the groups regarding final PANSS scores. CONCLUSION:: The results failed to demonstrate that the concomitant use of tDCS and cognitive training is effective to improve clinical outcomes in patients with schizophrenia. The present findings should be analyzed with care, considering the small sample size. Larger controlled trials on electric/cognitive stimulation should be produced in order to enhance therapeutic strategies in schizophrenia.

Faux Pas Test in schizophrenic patients / Teste de Faux Pas em pacientes com esquizofrenia

ABSTRACT Objective The aim of this study is to validate the adult version of “Faux Pas Recognition Test” created by Stone and colleagues (1998) as a reliable instrument assess and discriminate social cognition among schizophrenia patients and healthy controls. Methods This is a cross-sectional study with a total of 196 participants (mean age = 26.45; CI (95%) [25.10; 27.83]) 51% male. From those, 44 (22.4%) patients with schizophrenia and 152 (77.6%) healthy controls. The participants answered a short version of the Faux Pas Recognition Test, composed by 10 stories. Results Significant differences were found between both groups regarding their scores on Faux Pas Recognition Test (p = 0.003). Patients with schizophrenia had lower score, compared to healthy controls. Story 14 was the best to distinguish both groups, and Story 16, the worst. Among the questions of Faux Pas stories, the one related to intuition presented the most significant difference between the groups (p = 0.001), followed by the one related to understanding (p = 0.003). Conclusion The Brazilian version of the Faux Pas Recognition Test is a valid test to assess social cognition in schizophrenia and can be an important instrument to be used on the clinical practice.

RESUMO Objetivo O objetivo deste estudo é validar a versão brasileira da versão adulta do Teste de Reconhecimento de Faux pas criado por Stone e colaboradores (1998) como um instrumento confiável para avaliar e discriminar a cognição social entre pessoas com esquizofrenia e controles saudáveis. Métodos Trata-se de um estudo transversal com um total de 196 participantes (idade média = 26,45; IC (95%) [25,10; 27,83]), sendo 51% homens; destes, 44 (22,4%) eram pessoas com esquizofrenia e 152 (77,6%), controles saudáveis. Os participantes responderam a uma versão reduzida do Teste de Reconhecimento de Faux Pas, contendo 10 histórias. Resultados Foram encontradas diferenças significativas entre grupos no Teste de Reconhecimento de Faux Pas (p = 0,003). Pessoas com esquizofrenia obtiveram menor pontuação comparadas com o grupo controle. A história 14 foi a mais eficiente para distinguir os grupos, ao passo que a história 16 foi a pior. Quanto às questões das histórias Faux Pas, aquela referente à intuição foi a que apresentou maior diferença entre grupos (p = 0,001) seguida por compreensão (p = 0,003). Conclusão A versão brasileira do Teste de Reconhecimento de Faux Pas é um instrumento válido para avaliar a cognição social em esquizofrenia e pode ser um instrumento importante a ser usado na prática clínica.

Forensic neuropsychological assessment: clinical case of depression and working incapacity / Avaliação neuropsicológica forense: caso clínico de depressão e incapacidade para o trabalho

Issues related to mental health in relation to court matters have increasingly required the participation of the psychologist. We present the use of forensic neuropsychological assessment in a case of retirement reversal. Incapacity was attested due to disability resulting from depression of a 35-year-old attorney, and the case was forwarded from the courts to the Forensic Psychiatry and Psychology Unit at the USP Clinical Hospital. A clinical interview and application of cognitive tests was conducted. Despite the depression, significant cognitive losses that would prevent return to his professional assignments were not detected. The neuropsychological assessment has been shown to be an important tool in the forensic context, as it assists with diagnostic value for clarification of functional aspects in the various psychopathological areas in terms of disabilities or potentialities.

Assuntos relacionados à saúde mental na corte vêm demandando crescente participação de psicólogos. Sob este mote, apresentamos uma aplicação de um assessment neuropsicológico em um caso de reversão de aposentadoria por invalidez. Trata-se do caso de um juiz de 35 anos, que chegou à nossa Unidade de Tratamento Forense Psicológico e Psiquiátrico, no Hospital das Clínicas da Universidade de São Paulo. Para suprir a demanda, inicialmente conduzimos uma entrevista clínica e, em seguida, aplicamos uma bateria neuropsicológica, a partir da qual foi revelada a inexistência de limitações do desempenho cognitivo, as quais recomendariam a reafirmação do afastamento do profissional. Tal como revelado, o uso adequado do assessment neuropsicológico mostra-se uma importante ferramenta em contexto forense, auxiliando o esclarecimento de aspectos funcionais do diagnóstico, em vários contextos psicopatológicos.

Tendências metodológicas em marketing: entre as contribuições dos grupos focais as abordagens contemporâneas / Methodological trends in marketing: from the focus groups to the contributions of contemporany approaches

Percebe-se nas pesquisas em ciências sociais uma predominância histórica dos métodos quantitativos sobre os qualitativos, como parte da influência do pensamento positivista. Contudo, na atualidade, em contextos cujo foco se dá sobre os fenômenos intrínsecos às relações humanas (que por sua vez se inserem em um cenário social mais amplo), as abordagens qualitativas têm ganhado espaço. Se considerado o campo de estudos do marketing, mais especificamente do comportamento do consumidor, e em consonância com as demandas do mercado, algumas técnicas neurocientíficas vêm despertando a atenção, tanto por permitirem melhor avaliação de produtos quanto, com menor profusão, por facilitarem desenvolvimentos em branding (gerencia¬mento da marca), embora poucos estudos neurocientíficos em marketing venham sendo conduzidos na América Latina. O presente estudo apresenta uma atualização das tendências metodológicas que despontam no marketing, com ênfase em (1) grupos focais; (2) segmentação de mercado a partir da dis-tinção entre shoppers, consumidores e usuários; (3) neuromarketing. Em relação a este último, são apre¬sentadas ferramentas neurocientíficas (EEG, fMRI, ECG, RGP e rastreamento ocular) para a avaliação de aspectos não-declarativos do comportamento. Após a apresentação destas tendências, são discu¬tidas as possibilidades de integração que delineiam, sob a premissa de se fortalecer o campo.

When it comes to social sciences, one can detect a historical prominence of qualitative over quantitative methods, as part of the influence from positivist though. However, at present, in contexts where the focus is on phenomena intrinsic to human relations (which in turn are part of a broader social scenario) the qualitative approaches have been expanding. If one considers the marketing fields of study, specifically consumer behaviour, and in line with the market demands, some neuroscientific techniques have been emerging that allow a better product evaluation as well as, to a lesser extent, facilitate developments in brand management, though only a few neuroscientific studies in marketing have been conducted in Latin America. The present study offers a review of the methodological trends that emerge in marketing, with emphasis in (1) focal groups; (2) market segmentation stemming from the distinction between shoppers, consumers and users; (3) neuromarketing. Regarding the latter, neuroscientific tools are presented (EEG, fMRI, ECG, RGP and eye-tracking) for evaluation of non-declarative aspects of behaviour. Once these trends are presented, integration possibilities are discussed, for the sake of strengthening the field of study.
