Procedure
The training program was delivered to the parent who identified as the principal caregiver of their child with two in-person sessions at Children’s Centre (CC) and other sessions delivered via phone call, chat, and email message. The CARE booklet intervention (CBI) promoted the use of a printed booklet for written reports of different activities at home in four developmental dimensions commonly used for early screening. The intervention involved two in-person parent meetings in small groups (4–6 persons) and receiving instruction from a trained facilitator over one-hour sessions. The dosage per session was less than 50 minutes, to fit in with the high number of other scheduled activities in the CC. One facilitator, a final year-undergraduate student of Psychology at Universidad de la Sabana, oversaw the intervention. CBI required the use of a CARE booklet and materials delivered by the facilitator to parents in an initial session. Each other weekly session, was informed and delivered via phone call, chat, and email message. The remote weekly sessions were about specific activities presented for parents to carry out and report using their CARE booklet. The parental training emphasized the use of CARE to obtain information about daily interactions between parents/caregivers and children, and how the CARE booklet could help them to enhance their children’s development through regular monitoring of these interactions at home. The CARE booklet had a section for every activity with an area for daily marking, below instructions for how to report interactions daily for four weeks (see
