Matching procedure
RECRUITMENT
The recruitment pool of families will be identified via Statistics Sweden’s national registry. Matching will be made on the following variables: PATHS child’s gender, age (birthdates within 6 months), and living in the same postal code and/or municipality as the primary residence of the matched PATHS child. Statistics Sweden will identify a matched recruitment pool of families and provide contact information for the matched families to the research team (parents’ and matched child’s name, phone number, matched child’s home address). The research team is responsible for recruitment of all study participants.
