| Sumario: | Anxiety sensitivity (AS), hopelessness (H), sensation seeking (SS), and impulsivity (IMP) are traits implicated in substance misuse risk. Protective behavioral strategies for marijuana (PBS-M) are behaviors that decrease adverse effects of cannabis use. We hypothesized H, SS, and IMP would be associated with increased adverse cannabis outcomes via decreased PBS-M use, whereas AS would be indirectly associated with decreased cannabis outcomes via increased PBS-M use, and directly associated with increased cannabis-related problems. Analyses were conducted on data from N = 520 past six-month cannabis-using university students who completed measures of personality, PBS-M, cannabis use frequency, and cannabis-related problems. H and IMP were associated with more frequent and problematic cannabis use via decreased PBS-M use. AS was associated with less frequent and problematic cannabis use via increased PBS-M use. PBS-M may prove a useful intervention target to mitigate risk for frequent and problematic cannabis use in university students high on H or IMP.
