Confirming the Factor Structure of Attention-Deficit/Hyperactivity Disorder Symptoms in College Students Using Student and Parent DataFlorida State University, proctor{at}coe.fsu.edu
Florida State University, fprevatt{at}fsu.edu This study used confirmatory factor analysis to compare one-, two-, and three-factor models of attention-deficit/hyperactivity disorder (ADHD) symptoms to determine which model is the best fit for the data. Participants were 190 clinic-referred college students who had been evaluated for ADHD, 155 of whom had received a diagnosis. Data consisted of both self- and other (e.g., parent) ratings of both current and childhood symptoms. Symptoms came directly from the DSM-IV criteria for ADHD. A three-factor model, consistent with the DSM-III, was superior for current and childhood symptoms, regardless of rater (i.e., self or parent). The primary implication for these findings is that there may be a viable Impulsive subtype of ADHD within the adult population. Further research might include a closer examination of the unique functional limitations associated with impulsivity, as well as the development of diagnostic items that maximize model fit.
