BCT coder agreement
parent-related behaviors, child-
BCT inter-coder reliability, measured using PABAK, ranged from 0.76 to 0.89 for child- and parent-related behaviors targeted in all the coded RCT intervention materials (substantial to excellent agreement). Inter-coder reliability for identifying BCTs in the scaled-up version of INFANT ranged from substantial agreement for both child-related and parent-related behaviors targeted in the sessions (0.76 and 0.74, respectively), and moderate to fair agreement for child-related and parent-related behaviors targeted in the mobile app (0.44 and 0.40, respectively).
