Subthreshold psychotic symptoms in 22q11.2 deletion syndrome.

ABSTRACT:

Objective

Chromosome 22q11.2 deletion syndrome (22q11DS) confers 25% risk for psychosis and is an invaluable window for understanding the neurobiological substrate of psychosis risk. The Structured Interview for Prodromal Syndromes (SIPS) is well validated in nondeleted populations for detecting clinical risk but has only recently been applied to 22q11DS. We assessed the largest 22q11DS cohort to date and report on SIPS implementation and symptoms elicited.

Method

The SIPS, including its 19 subscales, was administered to 157 individuals with 22q11DS aged 8 to 25 years. Youth and caregiver interviews were conducted and rated separately, then compared for agreement. Implementation of the SIPS in 22q11DS was challenging because of the prevalence of developmental delay and comor
