The problem
Intervention: Parent-child free-play interactions with maternal and paternal behaviors (affection, responsiveness, encouragement, teaching) during 15-minute home-based sessions
Who it was tested with: 30 children aged 16-30 months and their mothers and fathers.
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"Thirty children aged 16-30 months participated in two 15-minute home-based free-play sessions, one with the mother and one with the father. Children's language measures included mother-reported receptive and expressive vocabulary using the MB-CDI, as well as observational language indices derived from the play sessions." The design measured the same children's language outcomes in relation to observed parental behaviors during naturalistic play, examining associations between parent interaction quality and child language achievement.
The study uses correlational associations rather than experimental design, so causal relationships cannot be established. The relatively small sample size of 30 children and lack of specified population characteristics limit generalizability. The study does not control for other variables that may influence language development.
