Teaching is a stressful profession given teachers’ competing demands. Due to COVID-19, teachers struggle to balance maintaining a safe classroom environment and the traditional child-directed focus of early education. The purpose of this study was to examine the effectiveness of an adaptation of Infant/Early Childhood Mental Health Consultation (IECMHC) on reducing teachers’ stress and examine associations between teacher stress and classroom practices. Measures were collected at baseline (T1) and 6-months post-intervention (T2) using the Childcare Worker Job Stress Inventory, an observational measure of classroom practices (Health Environment Rating Scale), and teacher-child interaction quality (Classroom Assessment Scoring System).
