The current study tested a model examining both the direct and mediated effects of Ethnic Cultural Norms (ECN) on cigarette use in a sample of Mexican American youth (ages 11-14; N=921). Contextual risk factors (peer smoking and family smoking) were included as potential moderators of this mediational relationship. A product of coefficient (alpha beta) method to test the significance of the mediated effect [Evaluation Review 17 (1993) 144.] was adapted to assess the mediation of interaction effects. Results suggested that Tobacco Avoidance Self-Efficacy mediated the protective influence of ECN on cigarette use. However, as peer smoking increased, the influence of ECN on cigarette use diminished, though it remained a significant, protective influence on cigarette use. Results are discussed in terms of the potential synergy between ECN and social influence training in tobacco preventive intervention development among youth of Latin descent.
本研究在一个墨西哥裔美国青少年样本（年龄11 - 14岁；N = 921）中测试了一个模型，该模型考察了民族文化规范（ECN）对吸烟行为的直接和中介效应。情境风险因素（同伴吸烟和家庭吸烟）被纳入作为这种中介关系的潜在调节因素。采用系数乘积（αβ）法来检验中介效应的显著性[《评估评论》17 (1993) 144]，以评估交互效应的中介作用。结果表明，控烟自我效能感介导了ECN对吸烟行为的保护作用。然而，随着同伴吸烟率的增加，ECN对吸烟行为的影响减弱，尽管它对吸烟行为仍有显著的保护作用。本文从ECN与社会影响培训在拉丁裔青少年烟草预防干预发展中的潜在协同作用方面对研究结果进行了讨论。
