The aim of this study was to examine the prevalence and types of psychiatric disorders among Bedouin adolescents with mild to moderate intellectual disability. This is the first study ever conducted on this topic within the Bedouin community in the Negev in Israel. The issue of psychiatric disorders among adolescents with intellectual disability is a complex one in general and even more so among the Bedouin population in the Negev, because of the large number of intellectually disabled children and adolescents in this community. The research population included 30 parents of 30 Bedouin adolescents with a mild to moderate intellectual disability attending a special education school in the Bedouin sector. The study used four research tools: the Schedule for Affective Disorders and Schizophrenia for School Aged Children (6-18 Years) Kiddie-Sads Present and Lifetime Version (K-SADS-PL); the Yale-Brown Obsessive Compulsive Scale (CY-BOCS); the Autism Screening Questionnaire (ASQ); and the Severity Scale of the Stereotyped Behavior Scale (SBS). The research results confirmed the initial hypothesis that there would be a high rate of psychiatric disorders in the research sample. Research findings indicated that 77% of the adolescents had at least one psychiatric disorder during the evaluation. The most common of these were autism-spectrum disorders 70% (21); disruptive disorders 47% (14); attention deficit and hyperactivity 47% (14); and anxiety disorders 40% (12). Other psychiatric disorders of lower frequency were also found and discussed in the findings. It is essential to continue the work started in this research, of examining the kinds and rates of occurrence of psychiatric disorders, on a larger sample of the same population, as well as paying closer attention to the disorders that this research found to be less common. On the level of practical implications, the main recommendation of this research is the need to develop diagnostic services and psychiatric and educational care for children and adolescents with intellectual disability in the Bedouin community in the Negev.
