Despite the emergence of new media technologies, television remains the most widely used screen media format. Unfortunately, concerns have arisen about its effects on the health and well-being of children and adolescents. This article reviews television usage trends and television's impact on sleep, attention, and interpersonal relationships. American Academy of Pediatrics recommendations on television use are also discussed. Many studies on television viewing have cross-sectional designs, and longitudinal research is limited. However, research to date suggests that excessive television viewing is associated with negative effects on sleep, attention, and interpersonal relationships. As use of different media formats escalates, research across multiple specialties (including child psychiatry) will need to incorporate evaluation of media use into its assessments. More research and education are needed on the appropriate use of media in youth. Information on the health effects of television may also increase awareness of potential issues with less well-studied media formats.

Velocardiofacial syndrome, now known as 22q11.2 deletion syndrome (22qDS), is estimated to affect more than 700 children born in the United States each year. Some clinical studies have found increased rates of schizophrenia in adults with 22qDS. However, these studies have been limited by small sample size and possible ascertainment bias. The psychiatric disorders most commonly reported in children and adolescents with 22qDS have been attention-deficit/hyperactivity disorder, oppositional defiant disorder, anxiety disorders, and major depression. Psychotic symptoms have been observed in 14% to 28% of children with 22qDS, but their clinical significance remains uncertain. A 5-year follow-up study of 22qDS children who reported psychotic symptoms at baseline found they had an increased risk for a subsequent psychotic disorder. Thus, a broad differential diagnosis should be considered when 22qDS children present with psychotic symptoms. Longitudinal studies are needed to better understand the full extent of the psychopathology associated with 22qDS.
