Episodic future thinking refers to the ability to travel forward in time to pre-experience an event. Although future thinking has been intimately linked with self and identity, to our knowledge, no prior research has compared episodic future thinking in populations with different substance use disorders. This study investigates whether there are differences in episodic future thinking between these alcohol and opiate users. The study recruited participants who were on the opiate substitution program (n = 31) and individuals who had been diagnosed with alcohol dependence (n = 21) from the Royal Prince Alfred Hospital Drug and Health Services. Healthy controls (n = 23) were recruited via Royal Prince Alfred Hospital databases and the general community. Past and future thinking was measured using four cue words. After each cue word, participants rated their phenomenological experience (e.g. emotion, reliving experience). Results indicated that alcohol-dependent individuals performed significantly higher in episodic future thinking compared to opiate users. These findings indicate that not all substance use disorder groups share similar episodic thinking capabilities. Our results suggest that the self-projection component of rehabilitation programs may have to be tailored to the different episodic construction abilities found in substance use disorder groups.
情景式未来思维是指能够穿越到未来预先体验某一事件的能力。尽管未来思维与自我和身份密切相关，但据我们所知，之前尚无研究比较过患有不同物质使用障碍的人群的情景式未来思维。本研究调查了这些酒精和阿片类药物使用者在情景式未来思维方面是否存在差异。该研究从皇家阿尔弗雷德王子医院药物与健康服务中心招募了参与阿片类药物替代计划的参与者（n = 31）以及被诊断为酒精依赖的个体（n = 21）。通过皇家阿尔弗雷德王子医院数据库和普通社区招募了健康对照组（n = 23）。使用四个提示词来测量过去和未来思维。在每个提示词之后，参与者对他们的现象学体验（如情绪、重温体验）进行评分。结果表明，与阿片类药物使用者相比，酒精依赖个体在情景式未来思维方面的表现显著更高。这些发现表明，并非所有物质使用障碍群体都具有相似的情景式思维能力。我们的结果表明，康复计划中的自我投射部分可能必须根据物质使用障碍群体中发现的不同情景构建能力进行调整。
