Ethics approval and consent to participate
: The DAGIS intervention study was found to be ethically acceptable, as the recruitment process for participation, by the University of Helsinki Ethical Review Board in Humanities and Social and Behavioral Sciences in May 2017 (22/2017). The two directors for all the municipality driven preschools gave their informed written consent to participate by email. Preschool managers in the municipalities were by a site visit informed about the study. Early educators got an oral presentation about the study through their preschool managers, and additionally by researchers conducting site visits. Even though preschools were participating, it was voluntary for early educators to answering the questionnaires (during working time). By answering the questionnaires, early educators gave their informed consent to participate in the study. An informed consent was obtained from all participating families before the study started.
