Co-regulation between young deaf and hard-of-hearing children and their caregivers: study protocol of Calming Together

The Calming Together study will be among the first to investigate co-regulation in young DHH children and their parents in ecologically valid home settings. By assessing both parent and child factors, it will provide insights into how co-regulation unfolds in daily life and how it relates to broader aspects of self-regulation. The study will also include both mothers and fathers to investigate their potentially unique contributions toward co-regulation and the development of self-regulation in DHH children. Findings may inform early intervention strategies to support parent-child interactions and enhance self-regulation in DHH children. The study was retroactively registered in Open Science Framework (OSF) on April 15th 2025 ( https://doi.org/10.17605/OSF.IO/CHEKA ).
