Resumen

Hasta ahora, los instrumentos para la valoración clínica de la impulsividad han dependido esencialmente de inventarios de personalidad o, en menor medida, de cuestionarios específicos. Por tanto, este texto presenta los resultados preliminares de una nueva escala de evaluación: la Escala de Evaluación de la Impulsividad (IRS). Esta escala es un instrumento de hetero-valoración de la impulsividad de 7 elementos basado en la conducta del paciente en situaciones habituales de la vida. La administración de la escala es sencilla y breve: 15 minutos. La IRS se puso a prueba en cinco muestras de población diferentes: 31 pacientes internos impulsivos, 36 adultos con episodio depresivo mayor, 15 sujetos de control sanos, 56 fumadores antes y después de una semana de supresión del tabaco y 47 pacientes internos adolescentes deprimidos antes y cuatro semanas después de tratamiento antidepresivo. Los resultados muestran buena validez de constructo, buena validez concurrente, buena fiabilidad interevaluador y sensibilidad al cambio. Un umbral de 8 para la puntuación total (rango de 0 a 21) da buena especificidad y sensibilidad. El análisis de componentes principales muestra la existencia de un factor principal compuesto por todos los elementos, con correlación más baja para dos elementos que pueden pertenecer a un segundo factor que requiere nuevas investigaciones.
