Coping Motives and Daily Negative Mood as Predictors of Cannabis-Related Consequences in Emerging Adults

Dr. Danielle Kofler, Bella Chang, Joanna Sie

ABSTRACT:

Coping motives, defined as using cannabis to manage negative affect, are consistently associated with cannabis-related consequences in emerging adults. Less is known about whether day-to-day fluctuations in negative affect contribute to this risk within individuals, or whether coping motives shape this relationship. The present study examined these relationships using a daily diary design. Sixty-three emerging adults aged 19 to 25, recruited across Canada, completed a baseline survey assessing trait coping motives (coping subscale of the Comprehensive Marijuana Motives Questionnaire), followed by 14 consecutive daily diary surveys assessing mood (PANAS-X-derived items) and cannabis-related consequences (Brief Marijuana Consequences Questionnaire). Multilevel Poisson models were used to examine within- and between-person predictors of daily consequences. Ethics approval was obtained from the University of Toronto Research Ethics Board. At the between-person level, higher coping motives were associated with greater daily cannabis-related consequences (b = 0.58, p < .001), explaining 32.6% of variance. At the within-person level, on days when individuals reported higher-than-usual negative affect, they also reported more cannabis-related consequences (b = 0.10, p < .001), accounting for 4.54% variance. A significant cross-level interaction (b = -0.06, p = .006) indicated that coping motives moderated this relationship, such that increases in negative affect were linked to sharper increases in consequences among individuals lower in coping motives, whereas those higher in coping motives reported consistently elevated consequences regardless of daily negative affect. These findings highlight the importance of considering both stable individual differences and day-to-day variability in understanding cannabis-related harm in emerging adults.
