Historical variation in drug use trajectories across the transition to adulthood: The trend toward lower intercepts and steeper, ascending slopes / Justin JAGER in Development and Psychopathology, 25-2 (May 2013)

BACHMAN, Auteur Article en page(s) : p.527-543 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examines historical variation in individual trajectories of heavy drinking and marijuana use from age 18 to 22. Unlike most studies that have examined cohort differences in drug use, it focuses on differences in both level of use and rates of change (growth). Nearly 39,000 youths from the high school classes of 1976–2004 were surveyed at biennial intervals between the ages of 18 and 22 as part of the national Monitoring the Future study. Between 1976 and 2004, adolescent heavy drinking decreased substantially. However, because the age 18–22 heavy drinking growth rate increased threefold for males and sixfold for females during this period, heavy drinking among 21- to 22-year-olds remained largely stable. The growth rate for marijuana use was more stable across cohorts, and historical declines in use were sizable across the entire 18–22 age band. Generally, historical variation in use was unrelated to college status and living arrangements as well as to historical changes in the distribution of young adult social roles. Findings suggest that historical fluctuations in use were less the result of proximal young adult factors and more the result of historical variation in distal adolescent factors, the effect of which diminished with age, especially for heavy drinking.

Substance use changes and social role transitions: Proximal developmental effects on ongoing trajectories from late adolescence through early adulthood / Jeremy STAFF in Development and Psychopathology, 22-4 (November 2010)  

Public ISBD [article]  inDevelopment and Psychopathology > 22-4 (November 2010) . - p.917-932 Titre : Substance use changes and social role transitions: Proximal developmental effects on ongoing trajectories from late adolescence through early adulthood Type de document : Texte imprimé et/ou numérique Auteurs : Jeremy STAFF, Auteur ; John E. SCHULENBERG, Auteur ; Julie MASLOWSKI, Auteur ; Jerald G. BACHMAN, Auteur ; Patrick M. O'MALLEY, Auteur ; Jennifer L. MAGGS, Auteur ; Lloyd D. JOHNSTON, Auteur Année de publication : 2010 Article en page(s) : p.917-932 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Substance use changes rapidly during late adolescence and early adulthood. This time in the life course is also dense with social role changes, as role changes provide dynamic context for individual developmental change. Using nationally representative, multiwave longitudinal data from age 18 to 28, we examine proximal links between changes in social roles and changes in substance use during the transition to adulthood. We find that changes in family roles, such as marriage, divorce, and parenthood, have clear and consistent associations with changes in substance use. With some notable exceptions, changes in school and work roles have weaker effects on changes in substance use compared to family roles. Changes in socializing (i.e., nights out for fun and recreation) and in religiosity were found to mediate the relationship of social role transitions to substance use. Two time-invariant covariates, socioeconomic background and heavy adolescent substance use, predicted social role status, but did not moderate associations, as within-person links between social roles and substance use were largely equivalent across groups. This paper adds to the cascading effects literature by considering how, within individuals, more proximal variations in school, work, and family roles relate to variations in substance use, and which roles appear to be most influential in precipitating changes in substance use during the transition to adulthood.
