Ecological validity of neuropsychological and personality measures of executive functions.
Associations between two types of measures of executive functions, namely, neuropsychological and personality, and measures of real-world behavior were investigated. Undergraduate students were administered neuropsychological measures of executive functions and completed a personality questionnaire developed to measure traits central to the construct of executive functions. Participants also reported on their behavior. Hierarchical regressions indicated that neuropsychological and personality measures of executive functions were significant predictors of different types of behavior. Neuropsychological measures predicted work behaviors and personality measures predicted substance use, risk-taking, and aggressive behaviors. Findings highlight the importance of including personality assessment in standard neuropsychological assessment in order to maximize ability to predict real-world behaviors relevant to independent and socially responsible functioning.
