Bidirectional associations between future time perspective and substance use among continuation high-school students.

ABSTRACT

We examined whether a bidirectional, longitudinal relationship exists between future time perspective (FTP), measured with the Zimbardo Time Perspective Inventory, and any past 30-day use of alcohol, tobacco, marijuana, or hard drugs among continuation high school students (N = 1,310, mean age 16.8 years) in a large urban area. We found increased FTP to be protective against drug use for all substances except alcohol. While any baseline use of substances did not predict changes in FTP 1 year later. The discussion explores why alcohol findings may differ from other substances. Future consideration of FTP as a mediator of program effects is explored.
