Feasibility of the Musical Contour Regulation Facilitation (MCRF) Intervention for Preschooler Emotion Regulation...

Emotion regulation (ER) describes the goal-directed ability to manage and shape the dynamics and timing of one's emotional experiences and expressions, an ability that develops early in life. Though development of maladaptive ER skills can significantly impact developmental outcomes, interventions for at-risk children are limited. The purpose of this mixed methods study was to examine feasibility and preliminary efficacy of the Musical Contour Regulation Facilitation (MCRF) intervention, a multi-session strategy for promoting ER development in preschoolers, with a focus on typically developing preschoolers as a preliminary exploration of a novel intervention. Eight typically developing children (M = 3.88 years) participated in the 11-session MCRF intervention across four weeks. ER-related behaviors were assessed pre- and post-intervention, and teacher interviews were conducted post-intervention. Teachers noted positive change in children's behavior following the intervention in terms of their emotion skills and peer interactions. Furthermore, they believed in the importance of music for developmental outcomes. Large and medium effects sizes in ER-related abilities were noted, and acceptability and integration of the intervention into the regular daycare environment was supported by interview data. Findings support further refinement and examination of the MCRF intervention in children who are at risk.
