Clinical Trial Summary

In the Playful Learning in Infancy Program, parents receive research-based educational guidance on playful interactions with their infants aged 0-1 year. They learn to recognize their infants' cues indicating readiness to engage in play and they are introduced to specific, developmentally appropriate activities for interactive engagement. The guidance is delivered to parents during routine home visits by public health visitors.

The aims of the Playful Learning in Infancy Program are to 1) promote playful interactions between infants and parents, parental attitudes towards play, and infant socioemotional development; 2) enhance the language and knowledge of playful learning in infancy among frontline staff; and 3) evaluate the Playful Learning in Infancy Program for potential testing in a future large-scale RCT study.

Evaluation is based on a parallel group study design, with half of the participants receiving care as usual and half of the participants receiving care as usual along with the Playful Learning in Infancy Program.
