RESUMO Objetivou-se determinar as propriedades psicométricas e a utilidade clínica do Breve Inventário de Dor Canina na língua portuguesa, em cães com displasia coxofemoral (DCF). O inventário foi preenchido por tutores de 43 animais com DCF e por 16 tutores de cães saudáveis. Os animais com DCF foram tratados com carprofeno 4,4mg/kg (GT = 21) ou placebo (GP =19), administrados uma vez ao dia durante quatro semanas. As avaliações foram realizadas duas semanas e imediatamente antes do tratamento, duas e quatro semanas durante o tratamento e após duas semanas do término do tratamento. A estrutura interna calculada pelo alfa de Cronbach = 0,97 indicou alta consistência dos dados. A análise dos componentes principais identificou a retenção de apenas um componente responsável por 78% da variabilidade dos dados. A análise da curva ROC indicou que o escore 3 discrimina cães saudáveis de cães com possível DCF (ASC de 0,973). Não houve diferença entre os cães tratados com carprofeno daqueles que receberam placebo. O questionário apresentou validade de constructo e critério e confiabilidade e pode-se empregá-lo para avaliar a dor crônica em cães com osteoartrite em países de língua portuguesa.

ABSTRACT This study aimed to determine the psychometric properties and clinical use of the Brazilian version of the Canine Brief Pain Inventory (CBPI) in dogs with hip dysplasia (HD). Forty-three dogs with HD and 16 clinically normal dogs were enrolled. The HD dogs were treated daily with 4.4mg/kg carprofen (GT = 21) or placebo (GP = 19), for four weeks. Owners completed the CBPI at two weeks (W-2) and immediately before the start of the treatment (W0), two (W2) and four (W4) weeks during treatment, and two weeks (W6) after the end of treatment. The internal structure was accessed, and the Cronbach’s alpha coefficient was 0.97, indicating the high internal consistency of the instrument. Principal Component Analysis (PCA) suggested the retention of one component, which accounted for 78% of the variability. The ROC curve analysis concluded that the score 3 has an excellent performance to discriminate between normal and possible HD dogs (AUC of 0.973). There was no difference between dogs treated with carprofen versus placebo. The instrument in Portuguese showed construct and criterion validity and reliability to be used in dogs with HD.

Abstract Short-term memory is a dynamic psychological process that operates within a network in which non-verbal intelligence and attentional domains are connected. However, no consensus has been reached about which process has the greatest effect on this memory ability, which was the main objective of the present study. A sample of 1448 Brazilian participants (mean age = 26.62 years, standard deviation = 9.97 years; 53.9% females) were collectively tested on pen-and-paper standardized and validated measures of selective (ROTAS-C), alternating (ROTAS-A), and divided (ROTAS-D) attention. They also performed the R1 Non-verbal Intelligence Test and a visual short-term memory test (Memória Visual de Curto Prazo [MEMORE] test). The statistical analyses consisted of a data mining procedure, in which exhaustive automatic selection screening was performed. The results were compared with Corrected Akaike Information Criteria. The linear model met the classic assumptions of ordinary least squares and only included main effects of selective attention (standardized β = 0.39) and non-verbal intelligence (standardized β = 0.37) as main predictors (F2,39 = 7.01, p < 0.01, adjusted R2 = 24%). The results are discussed within a cognitive psychology framework.

Resumo Universitários apresentam sintomas importantes de depressão e ansiedade. Este trabalho epidemiológico investigou a prevalência de tais sintomas em acadêmicos da Espanha, Portugal e Brasil, bem como as possíveis diferenças em função da nacionalidade e do gênero a partir de uma amostra representativa de 3 universidades (Universidade de Extremadura/Espanha = 1216; Universidade de Coimbra/Portugal = 426 e PUC-Rio = 315) em 2015. Análises descritivas e inferências indicaram que estudantes brasileiros, em especial as mulheres, apresentam maior manifestação de sintomas de depressão. Elas também apresentaram maior sintomatologia de ansiedade. A correlação entre depressão e ansiedade foi proporcional e forte e não houve diferença na ansiedade entre os países. Esta pesquisa pode ser utilizada em diversas áreas e auxiliar práticas clínicas e políticas públicas.

Abstract University students have shown a significant occurrence of depression and anxiety symptoms. This epidemiological work investigated the prevalence of such symptoms in university students in Spain, Portugal, and Brazil, as well as the possible differences according to nationality and gender from a representative sample of three universities (University of Extremadura/Spain, n = 1216; University of Coimbra/Portugal, n = 426, and PUC-Rio, n = 315) in 2015. The results suggest that Brazilian students have a greater manifestation of depression symptoms, especially women, and they also presented greater symptoms of anxiety. No difference was found in the anxiety results between countries. The correlation between depression and anxiety was positive and strong. This study can be of value in social, clinical and political settings.

Resumo Instrumentos de rastreio em saúde e educação oferecem indicadores rápidos que antecipam a avaliação diagnóstica e o tratamento. Frente às competências socioemocionais infantis, o Ages & Stages Questionnaires: Social-Emotional (ASQ:SE) foi utilizado na população de crianças matriculadas em pré-escolas públicas do município do Rio de Janeiro durante 2011. Posto isso, o objetivo desse trabalho foi investigar aspectos de validade e fidedignidade desse instrumento. Dados de 23.334 crianças (50.6% meninos), com idade média de 5 anos de idade (DP: 3 meses) e matriculadas em 625 pré-escolas foram analisados. A partir da Análise Fatorial Exploratória e Confirmatória, os resultados foram favoráveis ao modelo com um fator emocional e outro social: χ2 (463) = 46363.495, p < 0,001; RMSEA = 0,067; CFI = 0,918; TLI = 0,913. Indicadores de fidedignidade foram adequados. Os resultados evidenciaram aspectos de validade do ASQ:SE e possibilitam seu uso em crianças com 5 anos de idade.

A common feature of Alzheimer's disease (AD) is lack of awareness of neuropsychological deficit or illness, including poor appreciation of impaired task performance. Nevertheless, it has been shown in different clinical groups that levels of awareness may vary according to whether appraisal of symptoms is made in a first-or third-person perspective. This study explored this issue further in two experiments in which people with AD and control participants completed tests of memory and reaction time and had to judge both how difficult the tasks were for them and also for other people if they attempted the same tasks. Results showed that the AD group systematically indicated that others would do as well as they themselves had done. In comparison, control participants indicated other people would perform worse than they did themselves on the reaction time tasks, but similarly on the memory tasks. In addition, attribution of difficulty for self/other correlated with pre-morbid personality traits, such as neuroticism and agreeableness, in the AD group. The theoretical and clinical implications of these findings are discussed.

Objetivos Realizar uma revisão sistemática para compreender que fatores estão relacionados a uma maior ou menor consciência de morbidade no transtorno bipolar (TB), como o insight varia em função do estado afetivo e estabelecer uma comparação com outros transtornos mentais. Métodos Realizou-se uma revisão sistemática da literatura científica sobre o insight em pacientes com TB. Foram buscados estudos clínicos originais sobre o tema nas bases de dados Medline, ISI e SciELO. Os termos de busca empregados foram: “insight” OR “awareness” AND “bipolar” OR “mania” OR “manic”. Resultados Foram selecionados 55 artigos. O insight no TB parece ser mais prejudicado do que na depressão unipolar, porém menos do que na esquizofrenia. Com relação ao TB, um menor nível de insight está relacionado à presença de sintomas psicóticos e de alterações cognitivas. Além disso, um comprometimento do insight está associado a uma menor adesão ao tratamento. Por outro lado, uma maior preservação do insight pode estar associada a maior ideação suicida. Finalmente, a fase maníaca cursa com um nível inferior de insight quando comparada à fase depressiva ou de eutimia. Conclusão No TB, o insight está significativamente prejudicado, especialmente na mania. Diversos fatores clínicos parecem influenciar o nível de insight.

Objectives To conduct a systematic review to understand which factors are related to insight in bipolar disorder (BD), how insight varies depending on affective state and to establish a comparison between BD and other mental disorders. Methods We performed a systematic review of the scientific literature on insight in BD patients. Clinical studies on the topic were searched in the Medline, SciELO and ISI databases. The search terms used were: “insight” OR “Awareness” AND “bipolar“ OR “mania”. Results Fifty-five articles were selected. Insight in BD is more compromised than in unipolar depression, but less than in schizophrenia. A lower level of insight is related to the presence of psychotic symptoms and cognitive disorders. Moreover, insight impairment is associated with lower adherence to treatment. On the other hand, a greater preservation of insight may be associated with increased suicidal ideation. Finally, the manic phase is characterized by a lower level of insight than the depressive phase or euthymia. Conclusion Insight is greatly impaired in BD, especially during mania. Several clinical factors seem to influence the level of insight.

Em tarefas de reconhecimento facial, adultos e crianças apresentam dificuldade ao reconhecer faces de raças diferentes da sua. Esse efeito é conhecido como Efeito da Outra Raça (EOR) e tem sido consistentemente replicado em diversos estudos. O objetivo deste trabalho é apresentar uma revisão da literatura sobre alguns modelos teóricos que explicam sua emergência e desenvolvimento. Os modelos de codificação de faces baseado no Protótipo, e em Exemplares são a base para a explicação das diferenças na codificação entre faces da mesma raça e faces de outra raça. Uma revisão das recentes pesquisas sobre o EOR e como experiências com faces de outra raça, durante a primeira infância o influenciam, foi apresentada. Finalmente, pesquisas futuras relativas ao contexto cultural foram propostas, para melhor investigar o desenvolvimento do efeito da raça e dos modelos de codificação de faces.

In face recognition tasks, adults and children have difficulty recognizing faces from other races. This effect is known as the Other Race Effect (ORE) and has been consistently replicated in several studies. The aim of this paper is to present a review of some theoretical models that explain the ORE, its emergence and development. Face coding mechanisms based on Prototypes and Exemplars are the basis for the explanation of differences in coding between the same race and other race faces. It was presented a review of recent research on ORE and how the experiences with other race faces during early childhood influences the effect. Finally, further research on the cultural context has been proposed to better investigate the development of ORE and face coding mechanisms.

Objetivo: Investigar déficits cognitivos em pacientes com síndrome de Sjögren primária (SSP) utilizando bateria neuropsicológica breve. Método: Dezoito pacientes com SSP e idade entre 25 e 61 anos, foram submetidos a uma bateria neuropsicológica breve e os resultados comparados com 18 pacientes com esclerose múltipla e com 18 controles saudáveis. Resultados: A análise da variância revelou que os grupos clínicos apresentaram desempenho significativamente pior que os controles ao Rey Auditory Verbal Learning Test 3 (RAVLT 3; F 2,53 =3,500, p=0,038) e RAVLT 7 (F 2,53 =5,068, p=0,010). Os grupos clínicos apresentaram índices elevados de depressão pela Beck Depression Inventor y (BDI); (F 2,53 =0.003). O desempenho no Trail Making Test B-A revelou diferença significativa entre os grupos clínicos e o grupo controle (p=0,023). A análise de covariância tomando a BDI como covariante, não revelou mudanças nos resultados. Conclusão: Nosso estudo revelou comprometimento cognitivo em pacientes com SSP detectável por bateria neuropsicológica breve.

Objective: To investigate cognitive deficits in patients with primary Sjögren’s syndrome (PSS). Method: Eighteen patients with PSS, aged between 25 and 61 years, were subjected to a short neuropsychological battery and compared with 18 patients with multiple sclerosis and 18 healthy controls. Results: The analysis of variance (ANOVA) revealed that the clinical groups had significantly worse performance than the control group on the Rey Auditory Verbal Learning Test 3; (F 2,53 =3.500, p=0.038) and 7 (F 2,53 =5.068, p=0.010). The clinical groups had elevated levels of depression on the Beck Depression Inventory (BDI); (p=0.003). The analysis of the data from the Trail Making Test B-A revealed a significant difference between the clinical and control groups (p=0.023). The analysis of covariance with BDI score as a covariate, did not change the outcome. Conclusion: Our study revealed cognitive deficits in patients with PSS detectable by a short neuropsychological battery.

OBJECTIVE: To present the process of transcultural adaptation of the Richmond Compulsive Buying Scale to Brazilian Portuguese. METHODS: For the semantic adaptation step, the scale was translated to Portuguese and then back-translated to English by two professional translators and one psychologist, without any communication between them. The scale was then applied to 20 participants from the general population for language adjustments. For the construct validation step, an exploratory factor analysis was performed, using the scree plot test, principal component analysis for factor extraction, and Varimax rotation. For convergent validity, the correlation matrix was analyzed through Pearson's coefficient. RESULTS: The scale showed easy applicability, satisfactory internal consistency (Cronbach's alpha=.87), and a high correlation with other rating scales for compulsive buying disorder, indicating that it is suitable to be used in the assessment and diagnosis of compulsive buying disorder, as it presents psychometric validity. CONCLUSION: The Brazilian Portuguese version of the Richmond Compulsive Buying Scale has good validity and reliability

CONTEXTO: Alguns estudos indicam que a capacidade de autoavaliação do estado de humor está mais comprometida em pacientes com transtorno bipolar na mania do que na depressão. OBJETIVO: Estudar variações na autoavaliação do humor em relação ao estado afetivo atual em indivíduos com transtorno bipolar. MÉTODO: Um total de 165 pacientes com diagnóstico de transtorno bipolar tipo I ou tipo II tiveram seu estado afetivo avaliado utilizando os instrumentos Clinical Global Impressions Scale for use in bipolar illness (CGI-BP), Positive and Negative Syndrome Scale (PANSS) e Global Assessment of Functioning (GAF). Além disso, foi aplicada um instrumento de autoavaliação, a escala visual analógica do humor (EVAH). Os pacientes foram divididos em três grupos (eutimia, mania e depressão) e comparados quanto aos resultados da EVAH. RESULTADOS: Dos 16 itens da EVAH, 14 foram avaliados pelos pacientes em mania de forma semelhante aos pacientes em eutimia. Em contraste, em apenas dois itens, os deprimidos mostraram escores semelhantes aos eutímicos. CONCLUSÃO: Pacientes bipolares em mania, mas não os deprimidos, avaliam de forma não fidedigna seu estado afetivo, o que reforça o comprometimento do insight na síndrome maníaca.

BACKGROUND: Some studies indicate that mood self-assessment is more severely impaired in patients with bipolar disorder in a manic episode than in depression. OBJECTIVES: To investigate variations in mood self-assessment in relation to current affective state in a group of individuals with bipolar disorder. METHODS: A total of 165 patients with a diagnosis of bipolar disorder type I or type II had their affective state assessed using the Clinical Global Impressions Scale for use in bipolar illness (CGI-BP), the Positive and Negative Syndrome Scale (PANSS), and the Global Assessment of Functioning (GAF). In addition, participants completed a self-report visual analog mood scale (VAMS). Patients were divided into three groups (euthymia, mania, and depression) and compared with regard to VAMS results. RESULTS: Manic patients rated their mood similarly to patients in euthymia in 14 out of 16 items in the VAMS. By contrast, depressed patients rated only two items similarly to euthymic patients. CONCLUSION: Patients with bipolar disorder in mania, but not those in depression, poorly evaluate their affective state, reinforcing the occurrence of insight impairment in the manic syndrome.

Este estudo objetivou examinar os efeitos de um Treinamento da Memória de Trabalho (TMT) em idosos saudáveis. Vinte participantes compuseram a amostra final, onze do grupo experimental (TMT) e nove do controle (socialização). Todos foram submetidos a uma avaliação neuropsicológica pré e pós-intervenção. Os encontros foram realizados uma vez por semana, durante três meses. Houve melhora significativa, no grupo experimental, em atenção concentrada, aprendizagem, memória de curto prazo e episódica, e no grupo controle, em um menor número de variáveis, na atenção concentrada e memória episódica. O TMT parece ter promovido efeito de transferência, principalmente na memória episódica, que é relacionada diretamente aos subsistemas da memória de trabalho (MT), sugerindo que o TMT pode ser útil no contexto da neuropsicologia do envelhecimento.

The present study examined the effects of a Working Memory Training (WMT) in healthy elderly. Twenty participants comprised the final sample, eleven from the experimental group (WMT) and nine from the control group (socialization). Every subject underwent a neuropsychological evaluation pre and post-intervention. The meetings were held once a week, for three months. Results indicated that subjects in the experimental group improved cognitive functions related to concentrated attention, learning, short-term and episodic memory. Subjects in the control group also demonstrated, in a smaller number of variables, improvement in concentrated attention and episodic memory. WMT seems to have generated a transfer effect, especially to episodic memory, which is directly related to the subsystem of working memory (WM), suggesting that WMT may be useful in the context of the neuropsychology of aging.

The purpose of the present study was to investigate different memory systems among children of different school ages. Ninety children who attend schools within the Rio de Janeiro municipality school system, ages 6 to 10 years, were studied. The study excluded children with learning disabilities. All children underwent a neuropsychological evaluation. A two-way analysis of variance revealed significant gender differences in the free delay episodic memory. Age differences were found for the free delay episodic memory and recognition on the Rey Auditory Verbal Learning Test (RAVLT) as well as the recall of the Rey Figure. Semantic memory correlated with Semantic Verbal Fluency. Working Memory as measured by Digit Span subtest of the WISC correlated with the first list learning of the RAVLT. Overall, study results indicated a lower performance among 6-year-old children and gender differences in children 8 and 10 years of age. Data are consistent with the literature and show a distinction in the evolution of different memory systems throughout life.
