Sensation Seeking and Tobacco and Alcohol Use Among Adolescents:A Mediated Moderation Model

Based on ecological systems theory and social learning theory,this study constructed a mediated moderation model in which stressful life events moderated the relationship between sensation seeking and tobacco and alcohol use,and this moderation effect was mediated by affiliation with deviant peers. Participants were 660 adolescents,and they completed the sensation seeking scale,stressful life events scale,affiliation with deviant peers questionnaire,and tobacco and alcohol use questionnaire. The results indicated that:(1) adolescents’ sensation seeking was a risk factor of tobacco and alcohol use;(2) stressful life events moderated the effect of sensation seeking on tobacco and alcohol use;(3) affiliation with deviant peers mediated this moderation effect.
