Factor de independencia a la distracción en el trastorno por déficit de atención con hiperactividad: un modelo abreviado

José Antonio López Villalobos

Unidad Salud Mental SACYL

El factor independencia a la distracción (FID) del WISC-R presenta frecuentemente resultados inferiores al factor organización perceptiva (FOP) y comprensión verbal (FCV) en casos de Trastorno por Déficit de Atención con Hiperactividad (TDAH). La formulación FID< (FCV + FOP)/2 tiene buena sensibilidad para TDAH. El objetivo principal de este estudio ha sido reducir el número de pruebas necesarias para implementar la formulación FID < (FOP + FCV)/2, conservando sensibilidad para el trastorno y manteniendo buena concordancia con la fórmula completa. Se utilizó un diseño de investigación seccional, descriptivo y retrospectivo con 167 casos de TDAH, entre 6 y 16 años. Los casos fueron definidos según criterios DSM-IV y la evaluación se realizó mediante Child Symptom Inventory, Escala de Evaluación de Actividad Social y Laboral y WISC-R. Los resultados mostraron que la formulación abreviada reduce a la mitad el número de pruebas y tiene sensibilidad para TDAH del 83%, presentando concordancia casi perfecta con la versión íntegra. Mediante esta formulación el FID es significativamente inferior a la media del FCV, FOP y CIT en TDAH y las dimensiones de comorbilidad clínica, social y académica no influyen significativamente en la probabilidad FID< (FCV + FOP)/2.

The freedom from distraction factor in the attention deficit hyperactivity disorder: A short model. Attention deficit hyperactivity disorder (ADHD) usually presents a profile in which the freedom from distraction factor of the WISC-R (FDF) is affected to a greater extent than the verbal comprehension factor (VCF) and the perceptual organisation factor (POF). The formulation FDF< (VCF + POF)/2 has good sensitivity for ADHD. The aim of this study was to reduce the number of tests needed for the formulation FDF< (VCF + POF)/2, maintaining the sensitivity for ADHD and concordance with the complete formulation. A clinical sample of 167 children with ADHD is analysed (6-16 years). The cases of ADHD were defined according to DSM-IV criteria and they were assessed with WISC-R, Child Symptom Inventory and Social and Occupational Activity Assessment Scale. Lineal regression method was used to reduce the number of tests. The results showed that the short formulation reduces the number of tests by half and it has 83% sensitivity for ADHD. This formulation presents a good concordance with the complete version. The FDF is significantly lower than the VCF, POF and intellectual quotient in cases of ADHD. Comorbidity, social or school activity do not have a significant influence on the probability that FDF< (VCF + POF)/2.
