The construct validity was measured by means of confirmatory factor analysis, measurement invariance across gender and age categories will be tested. It is important to diagnose individuals with ADHD because although they are relatively leading normal lives, having families and jobs, they confront a wide range of problems in nearly all aspects of life due to this disorder.
