This is a national longitudinal study with three measurement points, with a three-month interval between each measurement. This means that we contact the participant three times to examine how they are doing over time.

Participants choose how they want to take part in the study – they can either fill out an online questionnaire or participate over the phone/video with assistance from a member of the research team. Participation in the study can be conducted in either Norwegian or English.

The study will collect self-reported data. Additionally, participants will be asked for consent to link the self-reported data to registry data on education and employment, as well as the use of specialized healthcare services.
