Effectiveness of rhythm and movement for self-regulation (RAMSR) for low socioeconomic preschoolers delivered by teachers trained online in Hong Kong

A randomized controlled trial in Hong Kong examined the effectiveness of the Rhythm and Movement for Self-Regulation (RAMSR) intervention for low socioeconomic status children's self-regulation. This is the first study of the intervention outside of Australia, and in which teachers were trained online to deliver the intervention (16 sessions over 8 weeks). Participants were 286 4-5-year-old children randomized at the classroom level (129 experimental, 157 control; 48.6% girls; 91% Chinese; Mage = 53 months) and their teachers (9 experimental, 8 control). Results from multi-level modeling revealed significant intervention effects for the intervention group across three time points (2022-2023) for teacher-reported self-regulation (np2 = .019), and the Head Toes Knees Shoulders task tapping executive function (np2 = .034).
