We investigated longitudinal predictors for disordered eating from early adolescence to young adulthood (12-34 years) across gender and different developmental phases among Norwegian young people. Survey data from a population-based sample were collected at four time points (T) over a 13-year time span. A population-based sample of 5,679 females…

The link between adolescent sexual activity and psychological well-being is a controversial issue in developmental psychology. This cross-sectional study investigated the association between three aspects of teenage sexuality (genital sexual experience, age of sexual onset, and number of sex partners) and positive well-being (hedonic, eudaimonic,…

Intergroup attitudes in children were examined based on Leyen's "infrahumanization hypothesis". This suggests that some uniquely human emotions, such as shame and guilt (secondary emotions), are reserved for the in-group, whilst other emotions that are not uniquely human and shared with animals, such as anger and pleasure (primary…

The present study is an examination of the attitudinal correlates of subjective age identification among the younger adults in a nationally representative sample of the United States…

The impact of divorce upon the children's adaptation has increasingly become a topic of concern in developmental research. This study investigates how specific coping resources (self-efficacy, self-esteem) vary according to age and as a correlate of developmental level in children from divorced and intact homes. Researchers also examined the…
