AB  - This study reported on the validation of the psychometric properties, the 
      factorability, validity, and sensitivity of the Dysexecutive Questionnaire (DEX) 
      in 3 clinical and nonclinical samples. A mixed sample of 997 
      participants--community (n = 663), psychiatric (depressed [n = 92] and anxious [n 
      = 122]), and neurologically impaired (n = 120)--completed self-report 
      questionnaires assessing executive dysfunction, depression, anxiety, stress, 
      general self-efficacy, and satisfaction with life. Before analyses the data were 
      randomly split into 2 subsets (A and B). Exploratory factor analysis performed on 
      Subset A produced a 3-factor model (Factor 1: Inhibition, Factor 2: Volition, and 
      Factor 3: Social Regulation) in which 15 of the original 20 items provided a 
      revised factor structure that was superior to all other structures. A series of 
      confirmatory factor analyses performed on Subset B confirmed that this revised 
      factor structure was valid and reliable. The revised structure, labeled the 
      DEX-R, was found to be a reliable and valid tool for assessing behavioral 
      symptoms of dysexecutive functioning in mixed community, psychiatric, and 
      neurological samples.
