本研究的目的是检查吸食大麻后驾驶的认知风险因素。我们测试了大麻结果预期和吸食大麻后对驾驶的具体认知是否与吸毒后驾车 (DWH) 和吸毒驾驶 (RWHD) 的可能性和频率独特相关。参与者是从中西部大学心理学入门课程中招募的大学生，他们报告称一生中曾经吸食过大麻，并报告称每月至少使用一次汽车或驾驶一次（n = 506）。 DWH 的感知危险性越大，DWH 和 RWHD 的可能性就会降低。消极的大麻预期与 DWH 的可能性降低相关，而社会规范与 RWHD 的可能性降低相关。对于有从事这些行为倾向的个体，所有认知预测因子都与 DWH 和 RWHD 频率的降低相关。研究结果表明，降低 DWH 和 RWHD 风险的干预措施可能会受益于针对大麻负面影响的普遍预期。同样，结果表明，增加学生对 DWH 潜在危险的了解可能有助于降低 DWH 和 RWHD 的可能性和频率。
The purpose of the present study was to examine cognitive risk factors for driving after use of marijuana. We tested whether marijuana outcome expectancies and specific cognitions about driving after marijuana use were uniquely associated with the likelihood and frequency of driving while high (DWH) and riding with a high driver (RWHD). Participants were college students recruited from introductory psychology classes at a Midwestern university who reported ever using marijuana in their lifetime and reported having access to a car or driving at least once a month (n = 506). Greater perceived dangerousness of DWH was associated with decreased likelihood of DWH and RWHD. Negative marijuana expectancies were associated with decreased likelihood of DWH, and social norms were associated with decreased likelihood of RWHD. All cognitive predictors were associated with decreased frequency of DWH and RWHD for individuals with the propensity to engage in these behaviors. Findings suggest interventions to reduce risk of DWH and RWHD may benefit from targeting general expectancies about the negative effects of marijuana. Similarly, results suggest increasing students' knowledge of the potential danger of DWH may help to reduce the likelihood and frequency of DWH and RWHD.
