The current study demonstrates the application of an analytic approach for incorporating multiple time trends in order to examine the impact of cohort effects on individual trajectories of eight drugs of abuse. Parallel analysis of two independent, longitudinal studies of high-risk youth that span ages 10 to 40 across 23 birth cohorts between 1968…

We use hierarchical cross-classified random-effects models to simultaneously measure age, period, and cohort patterns of mortality risk between 1986 and 2006 for non-Hispanic white and non-Hispanic black men and women with less than a high school education, a high school education, and more than a high school education. We examine all-cause…

Hierarchical linear models were used to examine trajectories of impulsivity and capability between ages 10 and 25 in relation to suicide attempt in 770 youths followed longitudinally: intercepts were set at age 17. The impulsivity measure assessed features of urgency (e.g., poor control, quick provocation, and disregard for external constraints);…

Examines the connections between the experience of social history and personality development. Outlines a model that demonstrates how the impact of social events is mediated by life stage. Interprets longitudinal data collected over the past 40 years on women's work and family lives in terms of the model. (FMW)

Explores the social determinants of the timing of the first birth in a nationwide sample of 6,752 women. Results showed education at marriage is the most important predictor. Although a few social determinants (i.e., race and religion) have a direct effect, most affect age at first birth through education. (JAC)
