The Rochester Intergenerational Study examines patterns in behavior over three generations

Growing evidence suggests that maltreatment is reproduced across generations as victims of maltreatment are at an increased risk for maltreatment perpetration. Unfortunately, little information about mediating pathways exists to provide an explanation for why maltreatment begets maltreatment. We use the number of types of maltreatment experienced to predict later maltreatment perpetration and then examine two developmental pathways that may serve as bridges between maltreatment victimization and perpetration: adolescent problem behaviors and precocious transitions to adulthood. With prospective, longitudinal data from the Rochester Youth Development Study, we assess the relevance of these pathways for the number of maltreatment experiences as well as the number of maltreatment victimization experiences by developmental period (i.e., childhood and adolescence). Our results demonstrate a significant relationship between maltreatment victimization and maltreatment perpetration. Adolescent delinquency and two precocious transitions, dropping out of school and independent living, as well as the accumulation of precocious transitions and problem behaviors, serve as mediators of this intergenerational relationship. Furthermore, the relationship between the number of types of maltreatment and subsequent perpetration is primarily driven by experiences of maltreatment during adolescence. We discuss the implications of these results and set an agenda for the development of programs and policies to interrupt the cycle of maltreatment.

We inquire how early in childhood children most at risk for problematic patterns of internalizing and externalizing behaviors can be accurately classified. Yearly measures of anxiety/depressive symptoms and aggressive behaviors (ages 6–13;  n  = 334), respectively, are used to identify behavioral trajectories. We then assess the degree to which limited spans of yearly information allow for the correct classification into the elevated, persistent pattern of the problem behavior, identified theoretically and empirically as high-risk and most in need of intervention. The true positive rate (sensitivity) is below 70% for anxiety/depressive symptoms and aggressive behaviors using behavioral information through ages 6 and 7. Conversely, by age 9, over 90% of the high-risk individuals are correctly classified (i.e., sensitivity) for anxiety/depressive symptoms, but this threshold is not met until age 12 for aggressive behaviors. Notably, the false positive rate of classification for both high-risk problem behaviors is consistently low using each limited age span of data (< 5%). These results suggest that correct classification into highest risk groups of childhood problem behavior is limited using behavioral information observed at early ages. Prevention programming targeting those who will display persistent, elevated levels of problem behavior should be cognizant of the degree of misclassification and how this varies with the accumulation of behavioral information. Continuous assessment of problem behaviors is needed throughout childhood in order to continually identify high-risk individuals most in need of intervention as behavior patterns are sufficiently realized.
