2.2. Population and sampling

Grandparents of any age, who self‐identified as primary caregivers to at least one grandchild for at least six months, consecutively or continuously, within the past two years were included in this study. Among those eligible, a maximum variation sample was selected to capture grandparent diversity with regards to age, sex, marital status and the number and age of grandchildren cared for. Participants were recruited through the networks of the two collaborating partners using purposive sampling. Staff in both partner organisations shortlisted grandparents in the NGO outreach programmes and those presenting at the hospital with their grandchildren during the recruitment period.
