title: Follow-up of a preschool epidemiological sample: cross-age continuities and predictions of later adjustment with internalizing and externalizing dimensions of behavior.
abstract: The continuity of behavioral adjustment from preschool through elementary school and junior high school years was examined. 541 children aged 9-15 years from a preschool epidemiological study were relocated and behavior checklist data obtained. Analyses focused on the relationship between internalizing and externalizing behavior dimensions from the preschool to follow-up periods. It was found that preschool externalizing symptoms were positively correlated with later externalizing and internalizing symptoms in the entire sample. Preschool internalizing symptoms, however, were predictive of later internalizing symptoms only for 2-year-old girls and 5- and 6-year-old boys. Similar results were obtained for clinically disturbed preschoolers. Results are consistent with previous findings regarding the longitudinal continuity of externalizing behavior but are at odds with reports of equal or greater stability of internalizing behavior. Given the magnitude of obtained correlations, even when significant, the results support the view that discontinuity rather than continuity in behavioral adjustment from preschool to later ages is the rule. The importance of examining other mediating variables in the prediction of behavioral adjustment and the need for models of development that encompass both stability and change are discussed.
