TI  - [Spanish version of the Dysexecutive Questionnaire (DEX-Sp): psychometric 
      properties in addicts and non-clinical sample].
PG  - 155-66
AB  - OBJECTIVE: Several studies have shown evidence of executive function impairment 
      associated with substance abuse. This suggests the potential usefulness of a 
      baseline assessment measure to screen for dysexecutive impairments in individuals 
      beginning treatment. The Dysexecutive Questionnaire (DEX) is a test widely used 
      to estimate executive dysfunction. The main objective of this work is to study 
      the psychometric properties of the Spanish version of the Dysexecutive 
      Questionnaire (DEX-Sp). A complementary goal is to study its potential utility 
      for initial screening in addicted individuals seeking treatment. METHOD: A sample 
      of 131 non-clinical and 127 clinical individuals meeting the DSM-IV-TR substance 
      abuse or dependence criteria were recruited. RESULTS: Internal consistency of the 
      questionnaire was assessed (Cronbach's Alfa=0.91), as well as other reliability 
      indicators. Exploratory and confirmatory factor analysis offers four- and 
      five-factor solutions. Also tested were the dimensionality and structural model 
      and its convergent and discriminant validity with other instruments. Differences 
      between clinical and non-clinical individuals and total scores were also 
      analyzed. CONCLUSIONS: The data suggest that the Spanish version of the DEX is a 
      useful measure for assessing general symptoms of dysexecutive syndrome, and a 
      valid, reliable and adequate screening test for estimating cognitive impairment 
      associated with substance abuse.
