Process flow diagram of the study protocol for phenotyping of 3q29 deletion syndrome. Assessment administration is determined based upon participant age, verbal ability, and evidence of active psychosis (defined as existing diagnosis of schizophrenia or evidence of psychosis without diagnosis). For participants under 18 years, the anxiety and autism sections of the KSADS are omitted to avoid overlap with the ADIS and ADI-R/ADOS-2. In this age group, child versions of the KSADS and ADIS are administered when the child’s communication ability and emotional status allow engagement in the interview. Participants 18–21 years are administered the KSADS (including anxiety section) in lieu of the SCID-V-R, if their level of communication ability and emotional status suggest the need for parental perspective.
