The impact of repeated maltreatment on behavioral trajectories from early childhood to early adolescence

Using multilevel model for change, this study examined the trajectories of both internalizing and externalizing behavioral problems from early childhood to early adolescence among a cohort of 685 children with early alleged maltreatment from age 4 through age 12. These children were recruited from five study sites using the LONGSCAN archive data. Repeated allegation of maltreatment for each child was treated as a time-varying variable and was tracked continuously and assessed at each measurement of the child behavioral problems. Child behavioral problems were measured at ages 4, 6, 8,10, and 12 using the Child Behavior Checklist. Findings indicated that repeated maltreatment significantly predicted subsequent trajectories of both internalizing and externalizing problems. In both cases, the effect of repeated maltreatment was on the slope, rather than on the intercept which was reflected in the trajectories. Repeated maltreatment was associated with significantly steeper increases in both internalizing and externalizing problems over time. Although there were no differences in early behavioral assessments (e.g., age 4 and age 6), both internalizing and externalizing behaviors emerged later and became more pronounced over time among those with repeated maltreatment (e.g., since age 8) compared to those without. Although behavioral problems may not be seen in younger children who experience multiple maltreatment, it is prudent to be aware that the impact may likely emerge in later ages of the child. Thus, ongoing monitoring and assessment of treatment needs for children who have had multiple occurrence of maltreatment becomes imperative. (C) 2013 Elsevier Ltd. All rights reserved.
