StayFine: Personalised Relapse Prevention of Anxiety and Mood Disorders in Youths

This study was previously pre-registered in the Netherlands Trial Registry (NTR) on December 15th 2019 with number NL8237. Enrollment started December 16th 2019. This new registry is made because an error was detected in the eligibility criteria listed on the NTR. That registry is taken offline and cannot be updated. Therefore the investigators registered the same study again, but now with updates to correct the wrongly entered information. The previously registered information is available through: https://trialsearch.who.int/Trial2.aspx?TrialID=NL8237 The eligibility criteria and outcomes as defined in the current registry of ClinicalTrials.gov were used from the start of the study and have not been changed during enrollment and recruitment. In the previous registry the use of a chat-group was mentioned in the intervention. Due to feasibility/planning issues, this was never implemented and therefore this is left out of the current registration. The outcome 'heart rate' is left out as well, because this outcome was not used after a switch in the wearable that measures activity level. Both changes were made before the first participant was enrolled in the study. The StayFine app runs on the Minddistrict web-based platform that has a CE-certificate.
