There are few studies of behavior problems in preterm children prior to 2 years old and the changes that occur over time. The aims of this study were to examine the patterns and prediction of behavior problems and the effects of gender and socioeconomic status (SES) on behavior problems in preterm children at the toddler and preschool periods.…

Previous research on sensation seeking (SS) was dominated by a variable-oriented approach indicating that SS level has a linear relation with a host of problem behaviors. Our aim was to provide a person-oriented methodology--a probabilistic clustering--that enables examination of both inter- and intra-individual differences in not only the level,…

Behavioral responses to stress and challenge are based in emotional and physiological arousal reactions. Adolescents with maladaptive or problematic behavior patterns, such as internalizing or externalizing problems, are likely to show atypical emotional and physiological reactions to stress. Relations between problems and reactions to stress were…

This study addresses the utility of the resilient, overcontrolled, and undercontrolled personality prototypes for predicting children's and adolescents' problem behaviour in a longitudinal general population sample (N = 491). Both parents and one child participated in the study at two measurement occasions separated by a 3-year interval. The major…

Results indicated that the two component solution of the Behar Preschool Behavior Questionnaire had a simpler structure and was easier to intepret than the three component solution. In addition, the two component solution was found to be stable across sexes, ages, socioeconomic populations, and cultures. (PCB)
