Informing Mothers about the Benefits of Conversing with Infants: Experimental Evidence from Ghana

We evaluate a low-cost intervention designed to boost parents’ verbal engagement with infants, which tends to be limited in developing countries. In our randomized experiment, recent or expectant mothers watched a three-minute informational video and received a themed calendar. Six months later, treated mothers reported stronger belief in the benefits of verbal engagement, more frequent parent-infant conversation, and more advanced infant language skills. Treatment effects on objective measures of parent-child conversation frequency and infant skills were positive but insignificant. We find larger immediate treatment effects on objective parent-child conversation, suggesting potentially larger long-term effects had the behavior change stuck more.
