Abstract:
The objective of this study was to test indirect effects of the Marijuana e-CHECKUP TO GO program on college students' frequent marijuana use through decreased use in specific social and academic activities. This study randomly assigned college students who reported frequent marijuana use (i.e., approximately five times per week) in fall 2016 to receive Marijuana e-CHECKUP TO GO or healthy stress management (HSM) strategies. The final baseline sample included 298 participants. Path analyses tested direct program effects on marijuana use at six-week posttest, as well as the indirect effect via use within four activities frequently participated in by college students: socializing, being physically active, studying, and being in class. Direct Marijuana e-CHECKUP TO GO effects on reductions in frequent use were transmitted by decreased marijuana use while studying and no use while socializing, being physically active, or in class. Marijuana e-CHECKUP TO GO may be most effective at reducing use of marijuana among college students while studying.
