ANÁLISIS PSICOMÉTRICO DEL "TEST DE FLUIDEZ DE DISEÑOS DE RUFF" EN POBLACIÓN UNIVERSITARIA DE BOGOTÁ

Abstract

Executive function is the construct that comprises the spectrum of cognitive abilities that enable the individual to anticipate, initiate, provide feedback to the behavior and have cognitive flexibility. One of the useful tests to assess this function is the Ruff Figural Fluency Test which measures visuomotor programming and is associated with right frontal activity. In Colombia this test has not been validated with adult population, and considering the usefulness of this instrument for assessing people with neurological injury, the need to carry out a study to analyze the feasibility of using this test both in research and clinical practice was raised. The overall objective was to conduct a psychometric analysis of the Ruff Test with university population in Bogotá. The study was descriptive, of instrumental type. Participants were 492 university students, men and women, aged between 18 and 28 years, enrolled in seven universities of the city of Bogotá. The internal consistency analysis yielded a Cronbach's alpha of 0.876. In order to establish convergent validity, the WAIS cubes subtest was used, and a correlation of 0.24 was found, with p = 0.001. Factor analysis yielded four factors, three of which coincide with the studies conducted by the author of the test. The fourth factor found was related with following directions. Sex differences were found in the unique designs factor, where women obtained a higher average than men.
