“…In recognizing the importance of understanding the determinants of early behavior problems, a growing body of research has focused on elucidating family risk factors. In particular, family instability, characterized by the cumulative amount of transitions experienced by the family (e.g., caregiver intimate relationship transitions, caregiver changes, residential moves, or caregiver income/job loss), has been identified as a consistent precursor of externalizing symptoms in childhood (e.g., Ackerman, Kogos, Youngstrom, Schoff, & Izard, 1999; Cavanagh & Huston, 2006; Milan, Pinderhughes, & Conduct Problems Prevention Research Group, 2006; Womack, Taraban, Shaw, Wilson, & Dishion, 2018). Because early childhood is a time when children are actively forming expectations about the consistency of their care and relationships with significant figures in their lives (Sroufe, 2000), instability experienced during this developmental period may have an especially pronounced impact on children's adjustment outcomes (Belsky, Schlomer, & Ellis, 2012).…”
