Episodic future thinking (EFT), a brief intervention involving mental simulation of positive future events, improves delay discounting (DD) in nicotine and alcohol dependent individuals. This study is the first to assess effects of a single-session, online episodic training (ET) on constructs that might impact cannabis use and cannabis use disorder. A sample of 200 active cannabis users recruited via Amazon Mechanical Turk were randomized to an EFT group (n = 102) or an episodic recent thinking control group (ERT; n = 98). A novel episodic specificity induction (ES) was included to enhance quality of episodic thinking for the ET group, and an ES attention control was provided to the ERT group (control training group; CT). Quality and manipulation ratings of event excitement, vividness, importance, and enjoyment of trainings were collected in addition to DD tasks (gains and losses) and readiness to change cannabis use. The ET group reported higher overall quality and manipulation ratings than did the CT group (p < .001, d = 0.79). DD of gains was lower in the ET relative to those of the CT group after controlling for relevant variables (p = .003, d = 0.48), unlike DD of losses (p = .50, d = 0.11). The ET group showed larger pre/post increases in readiness to change, but they were not statistically significant (p = .069, d = 0.26). These effects, following a session of online ET, suggests that ET may positively impact factors related to reduction in cannabis use. Differential effects of EFT and ES components on DD and the development of ET as an adjunctive mHealth intervention targeting reduction in cannabis use appears warranted.

基于网络的情景特异性和未来思考会议可调节大麻使用者的延迟折扣。

情景未来思维（EFT）是一种涉及积极的未来事件的心理模拟的简短干预措施，可以改善尼古丁和酒精依赖者的延迟贴现（DD）。这项研究是第一个评估单阶段在线发作训练（ET）对可能影响大麻使用和大麻使用障碍的结构的影响。通过Amazon Mechanical Turk招募的200名活跃大麻用户的样本被随机分为EFT组（n = 102）或突发性近期思维控制组（ERT； n = 98）。为了提高ET组的情节思维质量，加入了一种新颖的情节特异性诱导（ES），并向ERT组（对照组）进行了ES注意控制。事件兴奋度，生动度，重要性，除DD任务（获利和损失）以及改变大麻使用的意愿之外，还收集了培训的乐趣。ET组报告的总体质量和操作评分高于CT组（p <.001，d = 0.79）。在控制相关变量后，ET的DD值相对于CT组要低（p = .003，d = 0.48），这与DD的损失（p = .50，d = 0.11）不同。ET组在改变前/后表现出更大的改变准备，但在统计学上无统计学意义（p = .069，d = 0.26）。在在线ET会议之后，这些影响表明ET可能对与减少大麻使用有关的因素产生积极影响。EFT和ES成分对DD的不同作用以及作为针对减少大麻使用的辅助性mHealth干预措施ET的发展似乎是有保证的。
