Delivery path
SECONDARY
We delivered the Care Group intervention through the BPHS system at the township level. We established a three-tiered supervision mechanism at the national, county and village levels, carrying out quality assurance at the national and county levels at a quarterly, and at the village level at a monthly basis. We selected nine local women (including one health worker, one family planning worker, three experienced volunteers, three female caregivers, and one kindergarten teacher) who at least completed senior secondary education as facilitators after rounds of interviews and training. We used a two-phase training to help facilitators familiarize with the key messages and skills outlined in the Care Group Manual, and the training specifically emphasized and demonstrated how to promote positive relationships and cultivate a warm environment for participants.
