Changes to target population, target behaviors, and delivery features from RCT to scale-up
example behaviors
Enhancements to the INFANT intervention from efficacy testing to scale-up were informed by RCT and small-scale implementation experiences (Adjustments were made to the eligible target population for the INFANT intervention from the RCT to the scale-up. In the RCT, the intervention participants were first-time parents of children from 3 months of age. For the scale-up, the target population was expanded to any parents of children (as an option, determined by local sites) with intervention commencement from birth. Expanding beyond first-time parents and caregivers was to increase reach and potential benefits as well as fit adjusted local delivery set-up. Earlier intervention commencement was to enable inclusion of anticipatory breastfeeding information via the mobile app before the first group session.Target behaviors related to children and parents for the RCT and scaled-up version of the INFANT intervention were largely unchanged (Child and parent-focused behaviors targeted in the INFANT RCT and scale-up.Adapted from the TOPCHILD Collaboration target behavior clusters and example behaviors (Denotes behaviors added for the scale-up only.Delivery features related to children and parents for the RCT and scaled-up version of the INFANT intervention are described in Intervention delivery features of INFANT RCT and scale-up, including rationale for changes.Items and definitions from Hoffmann et al.
