INECO Frontal Screening (IFS): una herramienta psicométrica para evaluar la disfunción ejecutiva en policonsumidores

Abstract

This study analyzed the psychometric properties of the INECO Frontal Screening, IFS, in a population of polyconsumers of the city of Medellin, Colombia. The Psychometric analysis showed an acceptable consistency of the test: 0.7; with respect to its diagnostic utility, a cutoff point of 22.5 was estimated with a sensitivity of 80% and a specificity of 91%. As to its validity, evidence of criterion validity was found when comparing cognitive performance between the case and control group, obtaining significant differences: p <0.05, in each scale and total score. Finally, construct validity was performed through exploratory factor analysis, and the total variance explained of the 56% test was found, suggesting three factors, which contribute to the effectiveness of the IFS test to identify cognitive deficits in people with some type of neurological and neuropsychological dysfunction.
