Concurrent Life-Course Trajectories of Employment and Marijuana-Use: Exploring Interdependence of Longitudinal Outcomes Journal of Substance Abuse Treatment 45,5 (November-December 2013): 426-432. Also: http://www.sciencedirect.com/science/article/pii/S0740547213001153 Cohort(s): NLSY79 Publisher: Elsevier Keyword(s): Drug Use; Employment; Labor Force Participation This study analyzes data on 7661 individuals who participated in the 1979 National Longitudinal Survey of Youth (NLSY79) to estimate trajectories of employment and marijuana-use over a 17-year period. Bivariate random intercept and slope modeling is applied to examine concurrently the cross-correlation between the two concurrent longitudinal trajectories from age 23 to 39. Parameter estimates indicate baseline level (at age 23) of employment to be negatively correlated with marijuana, suggesting marijuana-use is associated with lower workforce productivity at age 23. The longitudinal employment slope is positively correlated with employment intercept for both males and females, indicating that survey participants with higher levels of employment at age 23 are more likely to have a positive impact on employment trajectory over time. For males, however, the employment slope is also significantly correlated with marijuana intercept (r = − 0.07), indicating marijuana-use in early adulthood may uniquely lower workforce productivity over age. |

Employment Trajectories: Exploring Gender Differences and Impacts of Drug Use Journal of Vocational Behavior 79,1 (August 2011): 277-289. Also: http://www.sciencedirect.com/science/article/pii/S0001879110002022 Cohort(s): NLSY79 Publisher: Elsevier Keyword(s): Drug Use; Employment; Gender Differences; Modeling, Growth Curve/Latent Trajectory Analysis; Substance Use This study investigated the impact of drug use on employment over 20 years among men and women, utilizing data on 7661 participants in the National Longitudinal Survey of Youth. Growth mixture modeling was applied, and five distinct employment trajectory groups were identified for both men and women. The identified patterns were largely similar for men and women except that a U-shape employment trajectory was uniquely identified for women. Early-initiation drug users, users of "hard" drugs, and frequent drug users were more likely to demonstrate consistently low levels of employment, and the negative relationship between drug use and employment was more apparent among men than women. Also, positive associations between employment and marriage became more salient for men over time, as did negative associations between employment and childrearing among women. Processes are dynamic and complex, suggesting that throughout the life course, protective factors that reduce the risk of employment problems emerge and change, as do critical periods for maximizing the impact of drug prevention and intervention efforts.
