Life Course Research Laboratory

Printer-friendly versionPrinter-friendly version

Researchers in this laboratory collect and analyze longitudinal data to delineate the development, etiology, and consequences of substance use over the life course. Longitudinal data sets span early childhood through adulthood and include both community and high-risk samples. In addition to substance use, research focuses on other problem behaviors, such as delinquency and violence, and how they are comorbid with substance use behaviors. Findings are used to inform the development of prevention programs.

Research Aim(s): 
  • Explication of a taxonomy of developmental trajectories of alcohol and drug use over the life course
  • Identification of developmental risk and protective factors for the onset and maintenance of use and problem use
  • Identification of short- and long-term consequences of use
  • Identification of antecedents to maturing out of substance use
  • Examination of the comorbidity of substance use with other problem behaviors, including criminal offending, street and intimate partner violence, child maltreatment, mental health problems, and risky sexual behavior
  • Examination of  ethnic/racial and gender differences in patterns, predictors, and consequences of substance use
  • Translation of etiological research into developing age-appropriate and culturally-appropriate preventive interventions
  • Development of measures of problem use (e.g., the Rutgers Alcohol Problem Index; RAPI)
Active Research Projects: 

The Simultaneous Alcohol and Marijuana (SAM) Project examines SAM use among college students at three state universities, each with very different state laws regarding marijuana use, using a two-phase approach: a larger survey assessment administered in the Fall semester of 2017 and Spring semester of 2018 (Phase 1, N = 1440) coupled with a fine-grained daily survey design (Phase 2, N =480) administered for 4 weeks each semester. Occasions of SAM use will be compared to occasions of alcohol and marijuana use alone, in terms of prevalence, frequency, patterning, mode/type of use, and use-related consequences. In addition, the study will examine within- and between-individual proximal and distal predictors of SAM use and examine the moderating effects of motivations and contexts on patterns of SAM use, occasions of SAM use, and negative consequences. Currently this project is funded by NIDA DA040880, 08/15/2016–03/31/2019.

The Rutgers Health and Human Development Project (HHDP), which began in 1979, is a prospective, longitudinal study of the emergence and unfolding of alcohol and other drug use behaviors in interaction with the individual's physical, psychological and social development from adolescence into adulthood. The design of the HHDP study involves three partially overlapping, longitudinal sequences each starting at a different age (12, 15, and 18) and spanning a combined age range from 12 to 31. This study has been funded by NIAAA, NIDA, NIJ, ABMRF/The Foundation for Alcohol Research, the Robert Wood Johnson Foundation, and the MacManus Foundation.

The Pittsburgh Youth Study (PYS) uses data from 1009 young men who were initially recruited from the Pittsburgh public schools in 1986 when they were either in the first or seventh grade. These young men (who were oversampled for risk for antisocial behavior) were interviewed at least every year until ages 20-25 and again in young adulthood at ages 26-36. Parents were interviewed until the youths were age 18 and teachers completed questionnaires through middle high school. Official criminal records have also been searched. With these data, we are studying racial differences in predictors and consequences of substance use and criminal offending over the life course. This study has been funded by OJJDP, NIMH, NIDA, NIAAA, CDC, the Pew Charitable Trusts, the Robert Wood Johnson Foundation, and the Pennsylvania Department of Health. Currently this project is funded by NIDA, DA034608, 04/01/2013–03/31/2017.

Rutgers Alcohol Problem Index (RAPI)
Created by Helene R. White, Ph.D. and Erich Labouvie, Ph.D., the RAPI is a 23-item self-administered screening tool for assessing adolescent problem drinking. It was developed in order to create a conceptually sound, unidimensional, relatively brief, and easily administered instrument to assess problem drinking in adolescence.
