Data management
USN
Data will be anonymized and stored on a restricted shared drive at the University of South-Eastern of Norway (USN) at USN Safe, to which only the research team will have access. Per the informed consent, anonymized data will be retained permanently (except in the case of withdrawal during the study) and may be released to other researchers. Identifying data (e.g., video films) will be deleted after 4 years. Data entry will be completed and checked by the research staff. Video data will be sent encrypted to the USN’s secure storage devices, accessible only by the research team. Physical data will be stored in locked cabinets within the Østfold University College and accessible only by the research team. Physical anonymized data, which describes the weekly summaries from the teachers, will be stored on a password-protected laptop computer.
