Linear/logistic regressions and mediation/moderation analyses were performed in a sample of 1,343 Belgian teenagers (15 to 16years old). SA was negatively related to lifetime cannabis use. Relaxation, social facilitation, and high-order positive expectancies moderated the relation between SA and lifetime cannabis use, whereas negative behavioral and high-order negative expectancies mediated the link. The potential protective nature of SA on lifetime cannabis use and the diverging involvement of negative and positive expectancies are discussed. Results support the importance of expectancies in prevention. 收起
