Background: Attention Deficit Hyperactivity Disorder (ADHD) is highly prevalent in school age children worldwide. Objective: This study was undertaken to assess the prevalence and association of ADHD with child demographics among a sample of Egyptian school age children. Patients and Methods: 111 children admitted to the outpatient pediatric clinic in Al-Azhar University hospitals were evaluated using Psychiatric interview-IQ and Conner's Abbreviated Rating Scale that consists of several behavioral parameters for the diagnosis of ADHD. Results: The most prevalent disorder in this study was learning disorder (23.1%) followed by ADHD (20.9%) and impulsive-hyperactive disorder (14.1%). The ADHD showed a positive correlation with conduct disorder, learning problem, psychosomatic disorder, impulsive-hyperactive disorder, and anxiety disorder. Male gender and consanguinity were significantly correlated with higher incidence of ADHD. Conclusion: The most prevalent disorder in this study was learning disorder (23.1 %) followed by ADHD (20.9%). ADHD was significantly correlated with other types of emotional and behavioral disorders. Also, male gender and consanguinity were a significant predictors for ADHD.

Middle East Current Psychiatry 2012, 19:56-63 ResultsCronbach's a coefficient (to test internal consistency) was found to be 0.90 for the total scale and satisfactory for the four subscales. Test-retest reliability was high for the total and subscales using a sample of 29 children and adolescents who were reassessed 1 month after the initial administration of the scale. Discriminant validity was assessed by comparing the responses of clinical groups with those from the community sample. The Arabic-translated version of CATS discriminated well between clinical groups and between clinical and nonclinical children and adolescents. ConclusionThe resulting Arabic-translated version of CATS is an acceptable, reliable, and moderately valid measure of negative automatic thoughts across emotional and behavioral disorders in children and adolescents. We expect that it will be used widely in Egypt and Arab countries.
