ABSTRACT
The present study sought to provide evidence of criterion validity for the Benton Visual Retention Test by making comparisons between older adults with and without a possible diagnosis of Alzheimer's disease. The control group was composed of 50 older adults, and the clinical group was composed by 16 subjects. Descriptive and inferential statistics were performed, including χ² test, F and Wald statistics, t-test, analyses of covariance with α = .05, and effect size calculations. We used a sociodemographic data form, the Geriatric Depression Scale-15, and Mini Mental State Examination. Despite the small clinical sample size, the results pointed to evidence of validity for the Benton Visual Retention Test for Administration A (Memory) and Administration C (Copy). The clinical group had significantly poorer performance on most scores. These results also indicate important deficits in other neuropsychological functions in Alzheimer's disease...

O presente estudo objetivou fornecer evidências de validade convergente entre o Teste de Retenção Visual de Benton (BVRT) e outros dois instrumentos de memória visual: Teste Pictórico de Memória (TEPIC-M) e Figuras Complexas de Rey. A amostra contou com 29 idosos, de ambos os sexos, com 60 a 79 anos e escolaridades baixa e média. Aplicou-se também a Escala de Depressão Geriátrica (GDS-15) e o Mini Exame do Estado Mental (MEEM), para excluir participantes com indício de depressão e/ou demência. Os resultados apontaram evidências de validade convergente entre o BVRT e o TEPIC-M, o que indicou que o BVRT também possui um cunho verbal, apesar de seus estímulos com figuras geométricas abstratas. Porém, houve poucas correlações significativas entre o BVRT e o teste Figuras Complexas de Rey, o que indicou que avaliam as mesmas funções de maneiras diferentes, além de haver diversidades importantes entre suas aplicações.
This study aimed to provide evidences of convergent validity between the Benton Visual Retention Test (BVRT) and two other instruments of visual memory: Teste Pictórico de Memória (TEPIC-M) and Rey Complex Figures. The sample consisted of 29 elderly of both sexes, 60 to 79 years old and low and middle education. Geriatric Depression Scale (GDS-15) and Mini Mental State Examination (MMSE) were used to exclude participants with signs of depression and / or dementia. The results showed evidence of convergent validity between BVRT and TEPIC-M, which indicated that BVRT also have a verbal nature, despite its abstract geometric stimuli. However, there were few significant correlations between BVRT and Rey Complex Figure test, which indicated that both evaluate the same functions in different ways, and there are important differences between their applications.

La muestra consistió de 29 ancianos de ambos sexos de 60 a 79 años y escolaridad baja y media. Se aplicó también la Geriatric Depression Scale (GDS-15) y el Mini Mental State Examination (MMSE), para excluir a los sujetos con síntomas de depresión y/o demencia. Los resultados mostraron evidencias de validez convergente entre el BVRT y el TEPIC-M, lo que indica que el BVRT también tiene un carácter verbal, a pesar de sus figuras con los estímulos abstractos geométricos. Sin embargo, hubo pocas correlaciones significativas entre el BVRT y las Figuras Complexas de Rey, lo que indica que evalúan las mismas funciones de diferentes maneras, además de diferencias importantes entre sus aplicaciones.
