ABSTRACT Adverse Childhood Experiences (ACEs) confer considerable risk for negative outcomes across the lifespan, but there is limited research examining whether the measurement of ACEs can be interpreted the same way across diverse groups of individuals. In particular, the measurement of ACEs among early child education teachers has received little attention. Given that millions of children receive care from early child education teachers, and evidence that ACEs can severely disrupt teacher’s abilities to support young children, it is critical to accurately assess for and respond to teacher ACEs. The present study examined the factor structure and measurement invariance of the 11-item Behavioral Risk Factor Surveillance Survey (BRFSS) version of the ACEs measure across a diverse group of teachers. Data were collected from 605 teachers in a southeastern state between 2018 and 2021. Teachers ranged in age from 18 to 81 years (35% young; 56% middle; and 9% older adults) and were diverse across race (46% White; 53% Black). Teachers completed the BRFSS version of the ACEs measure and a demographics questionnaire. Factor analyses replicated the theorized three-factor solution, with household dysfunction, emotional/psychological abuse, and sexual abuse emerging as distinct factors. Multigroup confirmatory factor analyses demonstrated measurement invariance across teacher age and race. Comparisons of scores indicated ACEs levels varied across teacher age and race. Overall, findings suggest the BRFSS version of the ACEs measure can be used to assess adverse childhood experiences across diverse groups of early child education teachers.
