National multi-cohort time trends in adolescent risk preference and the relation with substance use and problem behavior from 1976 to 2011

Publication Abstract

Keyes, Katherine M., Justin Jager, Ava Hamilton, Patrick M. O'Malley, Richard A. Miech, and John E. Schulenberg. 2015. "National multi-cohort time trends in adolescent risk preference and the relation with substance use and problem behavior from 1976 to 2011." Drug and Alcohol Dependence, 155: 267-274.

Aims

Preference for risky activities is an important developmentally-graded predictor of substance use. Population-level trends in adolescent risk preference, as well as the way in which risk preference may be a conduit to risk behavior, have never been documented. The present study examines population-level trends in risk preference among U.S. high school seniors for the 36 years from1976-2011, as well as trends in the association between risk preference and substance use and other problem behaviors.

Methods

Data were drawn from yearly nationally-representative cross-sectional surveys of US high school seniors (N = 91,860). Risk preference was measured consistently with two items. Marijuana and cocaine use, binge drinking, and conduct problems were assessed. Trends were tested using JoinPoint software.

Results

The mean level of reported risk preference among US 12 th graders has increased over time, especially in the 1980s. For example, the proportion of high school females who reported enjoying activities that were "a little dangerous" more than doubled, from 4.9% in 1976 to 10.8% in 1988. While risk preference reports among adolescent males leveled off in 1992, risk preference reports among females shows a continued positive overall slope through 2011. The magnitude of the association between risk preference and marijuana use has increased over time.

Conclusions

Reported preference for risky activities has increased among adolescents in the US, especially among young women. Reported risk preference is increasingly associated with a higher use of marijuana. Our findings argue for the importance of placing risk preference within a multi-level framework that attends to historical variation.
