ABSTRACT
Este estudo investigou os parâmetros psicométricos do teste de inteligência Matrizes Progressivas de Raven - Escala Geral para o estado de Minas Gerais. Participaram da pesquisa 1.956 pessoas, com idade entre 7 e 65 anos. A análise dos itens, por meio da Teoria de Resposta ao Item, modelo 2P, mostrou apropriados índices de dificuldade e discriminação de todos os itens, exceto o E12, o qual se mostrou extremamente difícil. A função de informação do teste indicou que o Raven foi respondido com relativa facilidade pela amostra de Minas Gerais. O efeito Flynn, ou ganhos cognitivos de geração, pode ser o fator responsável. A predição do desempenho escolar de crianças e adolescentes utilizando o teste Raven ainda é possível. Implicações para uso profissional são discutidas...
The psychometric parameters of the Standard Progressive Matrices of Raven (SPM) test for Minas Gerais state were investigated. 1956 people aged between 07 and 65 were the participants. The analysis of the items through the Item Response Theory, Model 2P, showed appropriate levels of difficulty and discrimination of all items except for item E12, which was extremely difficult. The test information function indicated that the SPM test was relatively easily to carry out by the sample of Minas Gerais. The Flynn effect, or cognitive gains of generation, may be the factor responsible. However, the prediction of school performance (criterion validity) using the SPM test is still possible. Implications for professional use are discussed...

Participaron de la investigación 1.956 personas, con edad entre 07 y 65 años. El análisis de los ítems utilizando la Teoría de Respuesta al Ítem, modelo 2P, mostró un buen ajuste de los índices de dificultad y discriminación de todos los ítems, excepto el ítem E12, que resultó ser extremamente difícil. La función de información de la prueba indicó que el test de Raven fue respondido con relativa facilidad por la muestra de Minas Gerais. El efecto "Flynn", o ganancia cognitiva de generación, puede ser el factor responsable. La predicción del desempeño escolar de los niños y adolescentes utilizando el test de Raven aún es posible. Se discuten las implicaciones para el uso professional del test...

OBJECTIVES: This study was aimed to compare abstract reasoning in patients with mental disorders;Depression, Schizophrenia, Organic Brain Syndrome(OBS), and normal control group using Standard Progressive Matrices(SPM), known as a test measuring visual pattern matching ability and reasoning ability by analogy. METHODS: SPM test in Vienna Test System was administered to 82 normal adults, 29 schizophrenic patients, 22 depression patients, and 32 OBS patients. SPM total score and 5 subtest scores in four groups were compared, using ANOVA and post-hoc comparison. SPM subtest scores in OBS and normal group were compared, using discriminant function analysis. RESULTS: SPM total score and all subtest scores in mental disorders group(schizophrenia, depression, OBS) were lower than in normal control group. SPM total score and all subtest scores in OBS group were lower than in schizophrenia and depression group. No difference between SPM total score in Schizophrenia and depression group was found. Discriminant function of B, E subtest was the hightest. CONCLUSION: The impairment of higher cognitive function, especially abstract reasoning impairment in OBS, was qualitatively different from that of schizophrenia and depression. SPM can differentiate specific pattern of abstract reasoning impairment in mental disorders, so SPM can be used not only as a substitute for intelligence test but also as a neuropsychological test.

OBJECTIVES: We conducted this study to provide standardized data of the computerized Standard Progressive Matirices(SPM)test in Korean adults. METHODS: The computerized SPM test was administered to 353 healthy volunteers aged 18 years over. We provided the standardized data(percentile and standardized T-scores)for the groups with similar mean and distribution of SPM scores, which was originally divided by age and sex. The validity of the new standardized data was tested by comparing IQs estimated by SPM and K-WAIS. RESULTS: The standardized SPM data were provided for four age groups: 18 to 30 years, 31 to 40 years, 41 to 50 years, 51 years and over. IQ estimated by this standardized data tends to be closer to IQ by K-WAIS than the IQ estimated by foreign normative data. CONCLUSION: The standardized data of the computerized SPM were proven to be a useful and valid tool for measuring IQ briefly, compared with the conventional way of measuring IQ.
