Abstract
Considerable heterogeneity exists in adolescent substance use development. To most
effectively prevent use, distinct trajectories of use must be identified as well as differential
associations with predictors of use, such as leisure experience. The current study used a
person-centered approach to identify distinct substance use trajectories and how leisure is
associated with trajectory classes. Data came from a larger efficacy trial of 2.249 South African
high school students who reported substance use at any time across 8 waves. Growth
mixture modeling was used to identify developmental trajectories of substance use and the
influence of healthy leisure. Results identified three increasing and one stable substance use
trajectory and subjective healthy leisure served to protect against use. This study is the first
of its kind to focus on a sample of South African adolescents and serves to develop a richer
understanding of substance use development and the role of healthy leisure.
