TI  - Fractionation of the dysexecutive syndrome in a heterogeneous neurological 
      sample: comparing the Dysexecutive Questionnaire and the Brock Adaptive 
      Functioning Questionnaire.
PG  - 615-21
AB  - PRIMARY OBJECTIVE: Research on the ecological validity of neuropsychological 
      tests of executive functioning has been limited by disagreement in the number and 
      make-up of the factors underlying the dysexecutive syndrome. The current study 
      sought to determine whether similar components of everyday executive dysfunction 
      are being measured by the Dysexecutive Questionnaire (DEX) and the Brock Adaptive 
      Functioning Questionnaire (BAFQ). RESEARCH DESIGN: Using the same sample, a 
      factor analysis of the DEX and the BAFQ was conducted to determine whether a 
      similar underlying factor structure for the dysexecutive syndrome would be found 
      across measures. METHODS AND PROCEDURES: The significant others of 46 adults with 
      varying neurological conditions completed the DEX and BAFQ. MAIN OUTCOMES AND 
      RESULTS: Behavioural inhibition, goal-directed behaviour/intentionality and 
      executive memory/cognition were found to be key underlying factors of the 
      everyday dysexecutive syndrome identified by both measures. The remaining factors 
      were divergent. CONCLUSIONS: Consistent with prior research, this study indicates 
      that the dysexecutive syndrome is multi-factorial. This research further 
      highlights core factors associated with real world executive functioning deficits 
      and demonstrates that the dysexecutive syndrome has distinct sub-components that 
      transcend the specific questionnaire measure used.
