The purpose of this study is to utilize the Extended Parallel Process Model (EPPM) to expand the construct of efficacy in the adolescent substance use context. Using survey data collected from 2,129 seventh-grade students in 39 rural schools, we examined the construct of drug refusal efficacy and demonstrated relationships among response efficacy (RE), self-efficacy (SE), and adolescent drug use. Consistent with the hypotheses, confirmatory factor analyses of a 12-item scale yielded a three-factor solution: refusal RE, alcohol-resistance self-efficacy (ASE), and marijuana-resistance self-efficacy (MSE). Refusal RE and ASE/MSE were negatively related to alcohol use and marijuana use, whereas MSE was positively associated with alcohol use. These data demonstrate that efficacy is a broader construct than typically considered in drug prevention. Prevention programs should reinforce both refusal RE and substance-specific resistance SE.
本研究旨在利用扩展平行过程模型（EPPM）在青少年药物使用背景下扩展效能的概念。我们使用从 39 所农村学校的 2129 名七年级学生中收集的调查数据，检验了拒绝毒品效能的结构，并证明了反应效能（RE）、自我效能（SE）和青少年药物使用之间的关系。与假设一致，对一个包含 12 个项目的量表进行验证性因素分析得出了一个三因素解决方案：拒绝 RE、酒精抵制自我效能（ASE）和大麻抵制自我效能（MSE）。拒绝 RE 和 ASE/MSE 与酒精使用和大麻使用呈负相关，而 MSE 与酒精使用呈正相关。这些数据表明，效能是一个比通常在药物预防中考虑的更广泛的概念。预防计划应加强拒绝 RE 和特定物质的抵制 SE。
