Recruitment
The first contact with the families will be by written letter to home addresses via regular post, subsequent contacts in the case of non-response will be by telephone or text message. If families consent to participate in the study, we will ask parents to update contact information for the family: parents’ and child’s name, home addresses, and phone numbers of parents/current legal guardians. This information is recorded on the consent signature form for parents stored electronically in an encrypted cloud service or on password-protected computers in a local, closed computer system at the Department of Psychology.
