Permission to draw data from registers was granted by the Danish Ministry of Health.

The genetic part of the study obtained ethical approval from the outset of the study and The Danish High Risk and Resilience Study –VIA 7 was later incorporated into the protocol (Arv og Miljø–genetics and environment) as an appendix, which has then been approved by the ethics committee (ARV OG MILJØ: betydning for psykisk sygdom hos børn og unge (H-B-2009-026)).
