The Conncrs Parent-Teacher Hating Scale has been uscd widely in assessment and treatment studies of Attention Deficit Hyperactivity disorder (ADHD) and proved to be of high reliability and validity. This study reports on the reliability and validity of the Arabic version of Conners Rating Scale as used by parents, teachers and other raters in three different groups of Egyptian children and adolescents. A healthy group of normal preschoolers, a medically referred group of children, and a group of children and adolescents with the diagnosis of ADHD. Test-retest and inter-rater reliability were analyzed. The high degrees of reliability for the normal preschoolers (r=0.96) and the ADHI group (r=0.64 and 0.68) in contrast to the medically referred grorup (r=0.53) are discussed. It is eniphasized that such a scale should be under no circumstances used as a means for diagnosing ADND in children, rather it should be viewed as providing additional data that may facilitate the interpretation of other clinic material and assist in the assessment of treatment efficacy.
