Cultural structures of the Persian parents' ratings of ADHD.

OBJECTIVE The objective was to study the cultural structure of Farsi-speaking parents' ratings with diagnostic definitions of ADHD. METHOD The children with ADHD and their parents were interviewed. The parents rated their children on the Farsi-speaking parents' ADHD rating questionnaire. RESULTS The principal components analysis extracted the two factors of inattention and hyperactivity- impulsivity. The items "often has trouble playing or enjoying leisure activities quietly," "Is often 'on the go' or often acts as if 'driven by a motor,'" and "Often talks excessively" were loaded on the impulsivity, not the hyperactivity factor. CONCLUSION The Farsi version of the items of the DSM-IV ADHD criteria consisted of two separate factors of hyperactivity-impulsivity and inattentiveness. In addition, the factor of hyperactivity-impulsivity consisted of two separate factors of hyperactivity and impulsivity. There are some differences in the items loading from previous studies in other cultures.
