Validity and reliability of Eysenck and Murray Impulsivity Scale and Divided Attention Questionnaire (DAQ) in students of University of Isfahan, Iran

The purpose of this study was to investigate the validity and reliability of Eysenck and Murray Impulsivity Scale and Divided Attention Questionnaire (DAQ) in students of University of Isfahan.
The statistical society included all of students of University of Isfahan in the academic year 2013-2014. Number of 200 students selected by multistage sampling method. Barratt Impulsiveness Scale (BIS-11) was used to assess the concurrent validity of Eysenck and Murray Impulsivity Scale and DAQ. Data were analyzed through chronbach's alpha, split-half coefficients, and Pearson and point-biserial correlation coefficients.
Our findings confirmed the concurrent validity of Eysenck and Murray Impulsivity Scale and DAQ based on significant correlations between scores of Barratt Impulsiveness Scale (BIS-11) with Eysenck and Murray Impulsivity Scale and DAQ (P0.05).
Based on the results of this study, the validity and reliability of Eysenck and Murray Impulsivity Scale and DAQ are appropriate to use in the population of Iranian university students.
