The purpose of this studywas to investigateFactorial StructureandPsychometric Properties of NadeauCollege-level ADHD Questionnaire-thePersian Version for Iranian university students. 612 students were selected from the population of undergraduatestudents in ShahidBeheshti University through proportional random sampling. These students filled out thePersian version of Nadeau College-levelADHD Questionnaire. To analyze the data,Cronbach's alpha coefficient and exploratory factor analysis were used.Cronbach's alpha coefficient for the whole questionnaire was 0.96. In the exploratory factor analysis ofthis questionnaire, byanalyzing the principal components, 9 factors were extracted: memory,organization, anxiety, aggression, academic performance, inattention,hyperactivity/impulsivity, having conflict tendencies, and self-regulation.Cronbach's alpha coefficient for extracted factors was between 0.74 to 0.90,and for the whole questionnaire it was 0.97. This showed an acceptable reliability in Persianversion of the questionnaire. Also, the high correlation coefficient amongfactors and the whole questionnaire,revealedappropriate structural validity of the questionnaire. Finally, by eliminating 25 items, the Persianversion with 100 items and 9 factors was extracted. This test had an appropriate reliability and validity for Iranian undergraduatestudents and it can be used tomeasure Attention-DeficitHyperactivity Disorder.
