ABSTRACT

La función ejecutiva es el constructo que reúne el conjunto de habilidades cognoscitivas que permiten anticipar, iniciar, retroalimentar el comportamiento y tener flexibilidad cognoscitiva. Una de las pruebas útiles para evaluar esta función es el Test de Fluidez de diseños de Ruff que mide la programación visomotora y se asocia con la actividad frontal derecha. En Colombia no se ha validado en adultos y, dada la utilidad del instrumento en población con lesión neurológica, se planteó la necesidad de realizar el estudio para analizar la viabilidad de utilizar esta prueba tanto en la investigación como en la práctica clínica. El objetivo general fue realizar un análisis psicométrico del "Test de fluidez de diseños de Ruff" en población universitaria bogotana. El estudio fue descriptivo, de tipo instrumental. Se contó con la participación de 492 estudiantes universitarios, hombres y mujeres, con edades comprendidas entre 18 y 28 años, de siete universidades de la ciudad de Bogotá. El análisis de consistencia interna arrojó un alfa de Cronbach de 0.876. Se utilizó la subprueba de cubos del WAIS para establecer la validez convergente, y se encontró una correlación de 0.24, con un valor p = 0.001. El análisis factorial arrojó 4 factores, tres de los cuales coinciden con los estudios realizados por el autor del test; el cuarto factor encontrado se relacionó con seguimiento de instrucciones. Se encontraron diferencias por sexo en el factor diseños únicos, en el cual las mujeres obtuvieron una media más alta que los hombres.


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.

ABSTRACT

OBJECTIVE: We investigated neuropsychological markers that can be used to discriminate pathological cognitive aging from normal cognitive aging. METHODS: We administered frontal lobe function tests including the Wisconsin Card Sorting Test (WCST), digit span test, lexical fluency test, fixed condition design fluency test, and Trail Making Test B (TMT-B) to 92 individuals with pathological cognitive aging (PCA) and 222 individuals with normal cognitive aging (NCA). We examined the main effects of participants' diagnoses (PCA, NCA) and age (65-69 years old, 70-74 years old and 75 years old or over) on their test performance using multivariate analysis of variance. RESULTS: The main effects of both the diagnosis (F=2.860, p=0.002) and the age group (F=2.484, p<0.001) were significant. The PCA group showed lower performance on the backward digit span test (F=14.306, p<0.001), fixed condition design fluency test (F=8.347, p=0.004) and also exhibited perseverative errors in the WCST (F=4.19, p=0.042) compared with the NCA group. The main effect of the diagnosis on the backward digit span test and the fixed condition design fluency test remained significant after Bonferroni correction. The main effect of age remained significant in the TMT-B (F=8.737, p<0.001) after Bonferroni correction. Other test scores were not influenced by diagnosis or age. CONCLUSION: The design fluency task may be a good neuropsychological marker to assess pathological cognitive aging.
