A cross-sectional study was conducted in spring 2000 to assess the problem of ADHD among schoolgirls in the Sultanate of Oman, an Arab country of 2 million people with a youth-based population. The aim of this study was to quantify the rate of ADHD in Oman and to examine its psychosocial and academic correlates. From three randomly selected public elementary schools in the Muscat area (Oman), representing all strata of Omani society, a sample of 708 schoolgirls (aged 6-13 years) was derived. The responsible teachers were asked to complete the Conners Teacher Rating Scale (CTRS) to determine symptoms of ADHD. The teachers were also requested to provide their subjective view of the pupil's behavior in the class regarding aggression, stealing, and lying. This study indicates that the prevalence of ADHD symptoms among Omani schoolgirls (according to the CTRS) is consistent with studies elsewhere, meaning that this diagnostic entity does exist in Oman. The association of aggression, poor school achievement, and lower intellectual level, symptoms of AHDH, is in accord with other studies.
