Prevalence rates of psychopathology in youth with 22q11DS compared to youth with idiopathic intellectual impairment and the general population. Figure derived from table from Fiksinski et al., Am J Med Gen A (2018). Data for youth with 22q11DS derived from Schneider et al. (2014) (805 individuals; note that the prevalence rate of psychosis is lower than the typically reported 20–25% in adults with 22q11DS, as these data only include youth). Data for youth with idiopathic intellectual impairment derived from Emerson & Hatton (2007) (641 individuals, age range 5 to 16 years, intellectual impairment based on parental/teacher report, most individuals estimated at a level of mild intellectual disability, the numbers represent point prevalence (i.e., symptoms present during the month—half year preceding the assessment); psychotic disorder not specifically reported). Data for general population youth derived from cohorts including both children and adolescents with exact age ranging vary between the different studies
