Episodic Future Thinking (EFT) utilizes participant-generated descriptions of future events to elongate an individual's temporal horizon. In EFT paradigms, the participant is asked to create and envision vivid descriptions of specific, positively valanced, events that could happen in the future. Recent research suggests that directing EFTs to focus on specific goals (i.e. evoking images of oneself engaging in activities consistent with a desired future outcome) are associated with stronger decreases in undesirable health behaviors. Thus, as part of the ETHoR condition, participants will be asked to verbally describe and imagine four specific events reflecting positive activities in which the participant engages in substance and incarceration-free activities, corresponding to predetermined future timepoints. The PRC will encourage participants to include as many contextual and emotional details as possible.

Individuals in the control group utilizes SET; an approach that controls for activation of episodic thinking but does not engage prospection (the hypothesized mechanism of episodic future thinking, future outcome) are associated with stronger decreases in undesirable health behaviors. Thus, as part of the SET condition, participants will be asked to verbally describe and imagine four current events reflecting positive activities in which the participant engages in substance and incarceration-free activities, corresponding to current experiences. The PRC will encourage participants to include as many contextual and emotional details as possible.

The adapted episodic future thinking (EFT) intervention will focus on generation of vivid, substance-free, rewarding events that could happen in an incarceration free future.

The computer based adjusting amount discounting task uses an adjusting algorithm to determine the amount of immediately available money that is equivalent to a large sum that is delayed by seven discrete durations of time presented in a randomized order (i.e., 1 day, 1 week, 1 month, 6 months, 1 year, 5 years, and 25 years). At each delay, a choice is first presented between the delayed larger sum and a smaller sum available immediately. For each trial, the position of the delayed and immediate amounts are randomly assigned and the participant chooses the preferred option by pressing the corresponding response button.

The Consideration of Future Consequences Scale1 (CFCS-14) is a 14-item self-report questionnaire that assesses active consideration of longer-term implications of an individual's actions. Lower scores on the CFCS-14 are associated with a greater focus on immediate needs and have been found to be associated with less engagement in health behaviors1819 and greater substance use. The measure has been used extensively among adult samples and demonstrates strong reliability and validity. Research suggests modest but significant correlations with the MCQ.

The SMAST is a brief questionnaire consisting of 13 items. It can be completed in just a few minutes and is designed for individuals with a reading level equivalent to that of a 7th grader. This assessment tool was derived from the Michigan Alcoholism Screening Test and has been found to be a reliable diagnostic tool to detect at-risk alcohol use, alcohol abuse, or alcoholism. The evaluation data suggests its effectiveness, with no notable occurrence of false positives.
