Declarations
:
: The Medical Ethics Committee of the Leiden University Medical Center, decided that the rules laid down in the Dutch Medical Research Involving Human Subjects Act (in Dutch: ‘Wet Medisch-wetenschappelijk Onderzoek met mensen’) did not apply to the research proposal (proposal number WSC-2022–38). The questionnaire was sent via an online platform and the data were processed without identifiers. We were unable to obtain informed consent, since the implementation impulses were not originally established with a research intention but rather to evaluate, assist, and monitor the implementation of the Childcheck. Nevertheless, the study ensured anonymity of CPs and adhered to ethical guidelines to protect their privacy.
