The 9-item SASCAT, a modified version of the Adapted Social Capital Assessment Tool (A-SCAT), is used to measure the individual social capital of caregivers of children aged 1 and 8 years old. The measure was first used in The Young Lives Study (www.younglives.org) in order to explore the association between caregiver’s social capital and different aspects of child well-being, for example educational outcomes and physical and mental health. The tool could also be used to measure ecological social capital by administering it to a representative sample of a community and aggregating their responses.
