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.

This report presents the rationale behind and the initial findings from a research project investigating the competence of children vulnerable to psychopathology. Four target groups were studied: (a) children with schizophrenic mothers, (b) children with internalizing mothers, (c) externalizing children, and (d) internalizing children. Each target child (N -120) was placed in an experimental triad with a matched and randomly selected control. Judgments of social and intellectual competence were made by peers and teachers in 113 classrooms in 37 elementary schools. Results are presented for each sex separately at the triad and target group levels. Overall, externalize rs were judged least competent followed in order of incrasing competence by children of schizophrenic mothers, internalizcrs, children of internalizing mothers, and controls highest of all.

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.

This study examined the incidence, prevalence, and severity of 14 empirically derived externalizing (unsocialized aggressive) and internalizing (socially withdrawn) behaviors among 2- through 5-year-olds attending day care. Teacher ratings were obtained for 558 children in the incidence sample and 709 children in the expanded prevalence sample. Within each age, data were cross-tabulated by sex of child and severity of behavior, and chi-square analyses were computed. Results indicated that a substantial proportion of children in the normal pre-school population exhibit relatively high severities of selected externalizing and internalizing behaviors; this proportion varied with the age of the child and the behavior rated. Preschool-aged boys were consistently rated as demonstrating greater frequencies of externalizing behaviors than preschool-girls. The diagnostic and clinical implications of these findings are discussed.
