Maltreatment history as persistent risk: An extension of Li and Godinet (2014)

• Maltreatment allegations significantly predicted subsequent trajectories of both internalizing and externalizing problems.
• For both types of problems, the effect of repeated maltreatment was on the rate of change (the trajectory).
• Behavioral problems emerge in younger children who experience maltreatment.
• Maltreatment history is a persistent risk factor for child outcomes through adolescence.
• A full assessment for maltreatment history would improve service plans for children with behavioral or emotional problems.

Using individual growth curves with mixed models, this study examined the influence of maltreatment on the trajectories of both internalizing and externalizing behavioral problems from early childhood (age 4) to late adolescence/emerging adulthood (age 16) in the LONGSCAN samples of children with early maltreatment exposure or early risk for maltreatment. Maltreatment reports for each child were used to create a time-varying predictor, which was assessed on an ongoing basis in the LONGSCAN study. Child/youth emotional and behavioral problems were measured at ages 4, 6, 8, 10, 12, 14, and 16 using the Child Behavior Checklist. Maltreatment allegations significantly predicted subsequent trajectories of both internalizing and externalizing problems. For both types of problems, the effect of repeated maltreatment was on the rate of change (the trajectory), and in the case of externalizing problems, this effect grew more pronounced through age 16. Although behavioral problems may not be seen in younger children who experience maltreatment, these children are at ongoing risk for such problems as they grow older, and this risk is either maintained through adolescence (in the case of internalizing problems) or increases in strength through adolescence (in the case of externalizing problems). Maltreatment history is a persistent risk factor for child outcomes through adolescence. Assessment for recent maltreatment, as well as for earlier history of maltreatment, in adolescent children would improve treatment and service plans for children with behavioral and emotional problems through adolescence.
