Cannabis use is increasing in the U.S. Driving under the influence of cannabis (DUIC) may be increasing as well potentially resulting in fatal and serious injury crashes. The purpose of this article is to explore the belief system associated with driving under the influence of cannabis (DUIC) using structural equation modeling (SEM). A sample (n = 2,084) of surveys collected from adults in the U.S. was analyzed using SEM to reveal the latent structure of the belief system associated with DUIC. The results of this analysis indicated that reported DUIC behavior (frequency and recency) was predicted by willingness that influenced intention. Willingness and intention were directly influenced by control beliefs, attitudes, norms, and attitudes (prototype image) toward people who never DUIC. Intention was also influenced by attitudes toward people who do DUIC. Intention had a stronger influence on DUIC than willingness alone. These components were influenced by underlying behavioral, normative, and control beliefs. Thus, strategies that can change these beliefs may also reduce DUIC.
在美国，大麻的使用呈上升趋势。受大麻影响下驾驶（DUI）的情况可能也在增加，从而导致致命和严重的撞车事故。本文的目的是利用结构方程建模（SEM）探讨与受大麻影响下驾驶（DUI）相关的信念系统。使用 SEM 分析了来自美国成年人的样本（n=2084），以揭示与 DUI 相关的信念系统的潜在结构。该分析的结果表明，报告的 DUI 行为（频率和近期）由意愿预测，意愿影响意图。意愿和意图受到控制信念、态度、规范以及对从不 DUI 的人的态度（原型形象）的直接影响。意图还受到对 DUI 人的态度的影响。意图对 DUI 的影响比意愿单独的影响更强。这些因素受到潜在的行为、规范和控制信念的影响。因此，改变这些信念的策略也可能减少 DUI。
