Evidências de Validade para o Teste de Retenção Visual de Benton (BVRT): Comparação de Grupos e Série de Casos em Pacientes Pós-AVC

Abstract

Investigaram-se evidências de validade de construto do Teste de Retenção Visual de Benton (BVRT) em pacientes após Acidente Vascular Cerebral (AVC). Participaram 42 adultos e idosos, 21 com AVC (11 com Lesão em Hemisfério Esquerdo -LHE, 10 com Lesão em Hemisfério Direito -LHD), e 21 controles neurologicamente saudáveis, emparelhados aos pacientes por sexo, idade e anos de estudo. Foram aplicados o BVRT e tarefas de percepção visual, memória de trabalho, memória visual e praxia construtiva. Os grupos clínicos (LHE e LHD) apresentaram desempenho inferior na Administração C (Cópia) do BVRT. Na análise de série de casos, três casos com LHD e três casos com LHE demonstraram dissociações entre Administração A (Memória) e Administração C (Cópia) do teste. Os resultados apontaram que alguns pacientes pós-AVC, mesmo em fase crônica, podem apresentar déficits nas habilidades visuoconstrutivas e déficits mais leves em memória visual. Portanto, foram encontradas evidências de validade para o BVRT.

The impact of affectivity on the behaviour of Portuguese adolescents / El impacto de la afectividad en la conducta de los adolescentes portugueses

“…Regarding the results obtained in the second hypothesis, in line with previous studies, girls score higher on prosocial behaviour and empathy (Sánchez-Queija, Oliva, & Parra, 2006) and on negative emotions (Gómez-Maquet, 2007), and they express more emotions than boys (Alcalá et al, 2006). Girls are more prone to expressing higher levels of happiness, sadness and fear (hypothesis 2a), while boys are more prone to expressing anger (Grossman & Wood, 1993;Marrero, Carballeira, & González, 2014;hypothesis 2b), although this information does not match other studies which claim that boys present more positive affects than girls (Noronha et al, 2014;Segabinazi et al, 2012).…”

“…En consonancia con investigaciones anteriores, las jóvenes puntúan más alto en comportamiento prosocial y empatía (Sánchez-Queija, Oliva, & Parra, 2006), en emociones negativas (Gómez-Maquet, 2007) y expresan más emociones que los chicos (Alcalá et al, 2006). Las chicas son más propensas a expresar índices más elevados de felicidad, tristeza y miedo, (hipótesis 2a), en cambio los chicos son más propensos a expresar emociones de ira (Grossman & Wood, 1993;Marrero, Carballeira, & González, 2014;hipótesis 2b), aunque estos datos no coinciden con otros estudios que aseguran que los chicos presentan más afectos positivos que las chicas (Noronha et al, 2014;Segabinazi et al, 2012).…”

Age, Education and Intellectual Quotient Influences: Structural Equation Modeling on the study of Benton Visual Retention Test (BVRT)

“…Table 1 presents the mean and standard deviation in IQ variables, age, years of education, the performances in scores of Rasch memory and Rasch copy of BVRT, and the Rasch score equivalent to a standardized score, with M = 0 and DP = 1 (for more information about the Rasch score was obtained, see Segabinazi et al, 2014). Significant differences were found among the four groups, F (12, 1734) = 65.25, p < .…”

“…In this study, the reliability (α) of Administration A (Memory) and Administration C (Form D) were .70 and form .72 respectively. The variable included in the model was a Rasch Score from Administration A (Memory) and Administration C (Copy) provided by previous studies (Segabinazi et al, 2014).…”

“…To contemplate the second objective of the study, which is to investigate the relationship between age, IQ and years of education with the performance BVRT, controlling the condition group (clinical vs control), was tested through structural equation modeling (SEM) models by specifying the items Administration A (Memory) of BVRT (B1 to B10 variables in the graph) as explained by a double imaging scale and the visual memory visuoconstructive abilities of individuals. This variable was estimated from a Rasch analysis with the items from Administration C (copy) of BVRT held in another study (Segabinazi et al, 2014). It is, therefore, a latent variable, but that, having been previously estimated from an independent set of indicators, was inserted as an observable variable in the model (variable "Visuo").…”
