During adolescence, sensation seeking is linked to several adverse outcomes including substance use, risk taking, and psychopathology. Recent empirical interest in the construct of boredom has revealed that some similar associations may exist for boredom during adolescence. Both boredom and sensation seeking peak during adolescence, and yet, research on boredom and its interaction with sensation seeking are limited. In a multi-cohort, US nationally representative sample of 8th and 10th grade students from the monitoring the future study, latent-moderated structural equation modeling was used to estimate the association of boredom, sensation seeking, and their interaction, to substance use, externalizing behavior, and depressive affect. Moderation by gender was also tested. Boredom and sensation seeking were both significantly associated with most dependent variables. Significant interaction effects were found wherein individuals high on both boredom and sensation seeking reported the highest levels of depressive affect and externalizing behavior. There were no significant interaction effects for substance use indices. Gender moderation was found for depressive affect. The results of this study demonstrate the generalizability of boredom associations and the significance of boredom by sensation-seeking interactions across multiple mental health domains during adolescence. Prevention efforts that attend to both boredom and sensation seeking may be particularly effective for promoting mental health and preventing externalizing behavior.
