The Disruptive Behavior Disorders (DBD) scale includes the "Diagnostic and Statistical Manual of Mental Disorders" (4th ed.) criteria for attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder, and conduct disorder. This study examined only the ADHD items of the DBD scale. This scale is frequently used for assessing parent- and teacher-reported ADHD symptoms. Although some research on teacher report exists, little is known about the factor structure of parent-reported ADHD for this scale, particularly for early adolescents. Confirmatory factor analysis was used to assess the fit of a priori specified, theoretically based models of ADHD. Participants were 250 parents of early adolescents (M = 12 years, SD = 1.53), who completed the ADHD items of the DBD scale. A two-factor model of hyperactivity/impulsivity and inattention provided the best fit to item responses, but localized areas of misfit were present. Alternate wording for a few items was proposed. Implications of the findings and directions for future research are discussed. (Contains 4 tables.)
