Latent growth curve modeling was used to study the co-development of internalizing and externalizing problems in a sample of 2844 Korean fourth graders followed over four years. The project integrated two major theoretical viewpoints positing developmental mechanism: directional model and common vulnerability model. Findings suggest that (a) boys…

This study aimed to explain why parental knowledge of adolescents' whereabouts declines with age. Such an investigation is important because previous studies have established an association between behavior problems and low levels of parental knowledge. A time-sequential sample comprising 2415 adolescents aged 13-18 years was investigated on five…

This study extends previous research investigating the developmental pathways predicting adolescent alcohol and marijuana use by examining the cascading effects of externalizing and internalizing symptoms and academic competence in the prediction of use and level of use of these substances in adolescence. Participants (N = 191) were drawn from a…

Two theoretical perspectives have been proposed to describe, explain, and intervene in adolescent development--prevention science and positive youth development (PYD). An integrative model bridging these two perspectives posits that it is important to assess the extent to which the same, similar, or complementary mechanisms may be responsible for…

Examines whether there are gender differences in changes in the aggregate level and individual stability of conduct problems from early adolescence to early adulthood. Analyzes self-reported data from a study of Norwegian adolescents. Analyses showed that involvement in conduct problems for both genders peaked in mid-adolescence. In the long term,…

The development of adolescents with severe behavioural problems receiving residential treatment in Holland was empirically studied during 1 year. Treatment methods included a standard program comprising behavioural modification and three specific treatment programs: psychodynamic treatment, structured community living and adventurous learning. The…

Seeks to review varied meanings regression has held within psychoanalytic and developmental literatures; focus on the forms, frequencies, and functions of regression when examining data from two structural developmental models addressing dimensions of normative adolescent identity development; and consider precipitants for different forms of…

Using a socio-ecological perspective, examines the influences of adolescents' social networks, personal resources, and environmental risks on adolescents' behavior problems across three samples of youth (N=155). Findings show that social support can operate as a protective agent or as a risk factor, depending on other characteristics of subsystems…
