TI  - [Factorial structure of the dysexecutive questionnaire in a sample of the Spanish 
      population with acquired brain injury and memory deficit complaints].
PG  - 641-50
AB  - INTRODUCTION AND AIMS: The dysexecutive questionnaire (DEX) has been used to 
      study executive deficits in both clinical samples (both psychiatric and 
      neurological) and non-clinical samples, although agreement on its factorial 
      structure is lacking. The aim of this research is to study that structure in the 
      self-administered version in a sample of the Spanish population with acquired 
      brain injury and memory loss complaints, and to compare that solution with those 
      obtained in other studies. PATIENTS AND METHODS: The questionnaire was 
      administered to 119 subjects with acquired brain injury with different 
      aetiologies (traumatic, vascular, tumours, multiple sclerosis, toxic-metabolic 
      and others). RESULTS: The Cronbach's alpha coefficient was 0.88. All the items 
      showed adequate discriminatory power, except item 15. No relation was found 
      between the total score on the DEX and the age, gender and time elapsed since the 
      injury. A negative correlation between total score and level of schooling was 
      confirmed. The total score does not follow a normal distribution. The five-factor 
      solution accounts for a higher percentage of the total variance than those of 
      two, three and four factors (63.76%). CONCLUSIONS: The Spanish version of the DEX 
      is an instrument that is valid for evaluating general dysexecutive symptoms in 
      subjects with acquired brain injury. The five-factor factorial structure 
      (planning, cognitive control, inhibition, social awareness and impulse control) 
      offers a greater wealth of information because it measures more aspects of the 
      dys-executive pathology and therefore appears to be more useful in the clinical 
      setting. It is advisable to use the questionnaire in an early stage of evaluation 
      or screening and to use it as a complement to the proxy-reported version.
