Declarations
:
: Each separate retrospective cross-sectional study protocol was approved by the Ethics Review Board of the University of Amsterdam (residential care center 2018-CDE-8871; special educational setting 2017-CDE-7603; alternative educational facility 2017-CDE-7736). In 2018 a new European law was implemented, which more often obligates active consent for retrospective case-file studies, known as General Data Protection Regulation (GDPR; General Data Protection Regulation, CitationRef removed). Since for the alternative educational setting data were collected before GDPR, no active consent was asked for that setting. In the residential care setting active consent to participate and publish was asked for case-files analyzed from the moment GDPR was implemented. The special education setting asked for an active consent from all informants (students, parents, teachers).
