背景：许多年轻人同时使用酒精和大麻 (SAM)，因此它们的影响重叠。人们对双重物质使用的动机以及与使用和后果的关联知之甚少。这项研究检查了交叉淡化动机与酒精和大麻使用水平及其后果之间的日常关联。方法：对前一个月报告使用 SAM 的年轻人进行了两次为期 14 天的突发调查。数据包括 281 名年轻人（18-25 岁；M 年龄 = 21.80，SD = 2.16；50% 女性）的 1049 个 SAM 使用天数。在调整一般增强、社交、应对和从众动机以及当天使用的酒精和大麻量后，多层次模型评估了交叉淡入淡出动机（即通过同时使用大麻和/或酒精使用来增强大麻和/或酒精使用的效果）对酒精和大麻使用及其后果的影响。结果：在 76% 的 SAM 使用日中，参与者认可交叉淡入淡出动机（即，以增强酒精或大麻的效果或同时喝醉和兴奋）。具有更强的交叉淡化动机与更多的饮酒、感知醉酒以及人与人之间和人内部水平的积极酒精后果相关。此外，在人与人之间，平均而言，报告更强的交叉淡化动机的人报告了更多的负面酒精后果和积极的大麻后果。某一天的交叉淡入淡出动机与当天的大麻使用或大麻后果无关。结论：交叉淡入淡出动机很常见，但每天都有所不同。了解双重物质使用的动机背景可能会支持未来的交叉淡入淡出干预措施。
Background: Many young adults engage in simultaneous alcohol and marijuana (SAM) use so that their effects overlap. Little is known about motivations for dual substance use and associations with use and consequences. This study examined daily-level associations between cross-fading motives and levels of alcohol and marijuana use and consequences.Methods: Young adults who reported SAM use in the month prior were surveyed in two 14-day bursts. Data included 1049 SAM use days from 281 young adults (age 18-25; M age = 21.80, SD = 2.16; 50 % women). Multilevel models assessed between- and within-person effects of cross-fading motives (i.e., to enhance the effects of marijuana and/or alcohol use by using them simultaneously) on alcohol and marijuana use and consequences, after adjusting for general enhancement, social, coping, and conformity motives and the amount of alcohol and marijuana used that day.Results: On 76 % of SAM use days, participants endorsed cross-fading motives (i.e., to enhance the effect of alcohol or marijuana or to get drunk and high at the same time). Having stronger cross-fading motives was associated with greater alcohol use, perceived intoxication, and positive alcohol consequences at the between- and within-person levels. In addition, between-person, individuals who reported stronger cross-fading motives on average reported more negative alcohol consequences and positive marijuana consequences on average. Cross-fading motives on a given day were not associated with marijuana use or marijuana consequences that day.Conclusions: Cross-fading motives were common and varied from day to day. Understanding the motivational context for dual substance use may support future interventions for cross-fading.
