Examined adjustment problems from late childhood to early adulthood among 500 Swedish girls. Found a diversified pattern of multisyndrome formation in late childhood. The syndrome structure in early adolescence identified externalizing adjustment problems and peer problems. An externalizing syndrome was stable between late childhood and early…

Used data from National Longitudinal Survey of Youth to model developmental trajectories across middle childhood. Found that individual trajectories were extremely diverse in level and sometimes in slope. Compared to girls, boys had heterogeneous slopes for math and behavior problems. Compared to boys, girls showed a significantly higher degree of…

Study of a cohort of low birth weight, preterm infants examined effects of maternal knowledge and concepts of child rearing on the home environment and developmental outcomes. Maternal knowledge, measured at 1 year, was found to be associated with quality of the home environment, the number of child behavior problems, and to a small degree, infant…

Analyzed individual developmental trajectories of disruptive behavior problems (DBP) between 3.5 and 6.0 years for children of adolescent mothers. Found that DBP decreased with age. Boys and children of more depressed/anxious mothers exhibited higher levels of DBP. Maternal negative control was associated with level of DBP and change rate, and…

Identified groups of economically disadvantaged children showing high externalizing behavior in first grade that persisted (persistent) or decreased (improver) in third grade, or low first- grade levels that were stable (unproblematic) or increased (new problem) in third grade. Found that verbal ability, behavioral impulsivity, parent…
