Many developmental theories have not been sufficiently evaluated using designs that control for unobserved familial confounds. Our long-term goal is to determine the causal structure underlying associations between early environmental conditions and later psychosocial and health outcomes. Our overall objective in this study was to further evaluate…

Differentiation of intelligence refers to changes in the structure of intelligence that depend on individuals' level of general cognitive ability (ability differentiation hypothesis) or age (developmental differentiation hypothesis). The present article aimed to investigate ability differentiation, developmental differentiation, and their…

Researchers are increasingly recognizing the transition to adulthood as an important developmental stage between adolescence and adulthood (Arnett 2004). Many important processes occur during this period in a young adult's life, including leaving home and forming a family. One crucial activity during the transition to adulthood is successful…

This fact sheet considers differences in behaviors and outcomes between young men and young women as they transition to adulthood. It also considers whether differences between young men and young women are related to the fact that some women are caring for children. Using the National Longitudinal Survey of Youth 1997, the analysis compares…

In 2007, nearly 40 percent of children in the United States lived in low-income families--families with incomes at or below 200 percent of the federal poverty level (FPL). Youth from low-income families are vulnerable to poor outcomes as adults, as these youth often lack the resources and opportunities found to lead to better outcomes. This fact…

The transition to adulthood can be particularly challenging when a young adult experiences mental health problems. This fact sheet uses data from the National Longitudinal Survey of Youth 1997 to explore the young adult outcomes and adolescent risk behaviors of youth suffering from depression and anxiety as they make this transition. Depression…

Presents a model of moral identity formation. Examines the model using data from the National Longitudinal Survey of Youth (Child Sample) to assess the influence of family environment on moral identity formation. Reveals that cognitively- and socially-rich family environments and high levels of adolescent-parent joint activity facilitated…

Used data from National Longitudinal Survey of Youth to model developmental trajectories across middle childhood. Found that individual trajectories were extremely diverse in level and sometimes in slope. Compared to girls, boys had heterogeneous slopes for math and behavior problems. Compared to boys, girls showed a significantly higher degree of…
