Examined the number and nature of temperamental types in 488 children, age 3 years 6 months. Configural-frequency-analysis methods showed clear support for two temperament types: controlled-nonexpressive and noncontrolled-expressive. These types showed meaningful differences against external criteria related to a wide range of problem behaviors.…

A theoretical model was examined linking early adolescent interpersonal relatedness and self-definition, autonomous and controlled regulation, and negative and positive life events. Findings indicated that self-criticism predicted less positive events, whereas efficacy predicted more positive events. Effects were fully mediated by absence and…
