• Resumen

  • Diversos estudios han evidenciado el deterioro de las funciones ejecutivas asociado al abuso de sustancias. Este hecho sugiere la conveniencia de contar con algún instrumento de cribado que sirva para establecer una línea base sobre los déficits que presentan los sujetos que inician tratamiento. El Cuestionario Disejecutivo (DEX) es un test ampliamente utilizado para estimar disfunción ejecutiva. El principal objetivo del presente trabajo se centra en estudiar las propiedades de la versión española del Cuestionario Disejecutivo (DEX-Sp). Complementariamente se pretende estudiar su potencial utilidad como instrumento de cribado en adictos en tratamiento. Método: 131 sujetos de población no clínica y 127 adictos (con criterios DSM-IVTR para abuso o dependencia). Resultados: Se estudia la consistencia interna ( de Cronbach = 0,91) entre otros indicadores de fiabilidad. El análisis factorial exploratorio y confirmatorio ofrece soluciones de 4 y 5 factores. Se estudió la dimensionalidad y el modelo estructural de base, así como la validez convergente y discriminante. Se estudiaron las diferencias apreciadas entre adictos y población no clínica. Conclusiones: Los datos sugieren que la versión española del DEX es un instrumento útil para evaluar síntomas disejecutivos generales, con la suficiente fiabilidad y validez para explorar deterioro cognitivo asociado al abuso de sustancias.
