Change in Delay Discounting 5 Trial Adjusted Measure |
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 the left or right portion of the screen, and the participant chooses the preferred option by pressing the corresponding left or right response button. Change in the Delay Discounting score is measured by comparing baseline scores with scores at the intervention (baseline) and the post-intervention assessment (approximately 7 weeks after baseline) |

Change in Consideration of Future Consequences Scale |
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. Change in CFCS-14 score is measured by comparing baseline scores with scores at the post-intervention assessment (approximately 7 weeks after baseline) |

Change in Tower of Hanoi |
Tower of Hanoi (TOH) is a measure of planning ahead. It requires the participant to move disks of varying sizes between three pegs in order to create a specified design. Participants are instructed to follow specific rules for play and are awarded points for making each design in the least number of moves. The current study will use the TOH measure from the Delis-Kaplan Executive Function System (D-KEFS; Delis, Kaplan & Kramer, 2001). The test is normed on clinical and community samples of individuals ages 8 to 89 years old and demonstrates adequate reliability and validity (Delis et al. 2004). |

Change in Letter Number Sequencing |
Letter Number Sequencing (LNS) is a measure of working memory. The participant is read a list of scrambled letters and numbers that they must then repeat back to the examiner in alphabetical and numeric order. The length of the target string increases over time until the participant is no longer able to correctly sequence three letter/ number stems in a row. The investigators will utilize the LNS subscale from the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-5; Wechsler, 2014) for participants between 12 and 16, and the Wechsler Adult Intelligence Scale (WAIS-IV; Wechsler, 2008) for participants age 17. Both intelligence batteries are widely used and normed on community and clinical populations. |

Change in Iowa Gambling Task |
Iowa Gambling Task (IGT; Bechara et al., 1994) evaluates experiential decision making. It is administered via a computer interface, in which participants are presented four decks of cards and asked to select one deck to flip a card from in order to win money. Each deck is associated with specific winning and losing probabilities and performance on the task is determined by computing relative preference for longer vs. shorter-term rewards. The IGT has been shown to be valid in child and adolescent populations (Beitz, Salthouse & Davis, 2014; Smith, Xiao & Bechara, 2012). |

Change in Youth Risk Behavior Survey |
The Youth Risk Behavior Survey (YRBS; CDC, 2001) is a self-report measure of the prevalence of real world risk behaviors, including compromised safety behaviors (e.g. not wearing a seat belt), substance use, risky sexual practices, and delinquent behaviors (e.g. gambling, theft). Because substance use has been associated with problematic behaviors more broadly (Bukstein, 2000), the YRBS will allow us to tap engagement in a variety of related risky behaviors. Consistent with previous research, the investigators will create an aggregate of substance use and risk behaviors (e.g. Aklin et al., 2005) as an index of risky behaviors. Composite scores such as these have demonstrated adequate psychometric properties (e.g. Felton, et al., 2015). |

Change in Alcohol Effect Expectancies |
The Alcohol Expectancy Questionnaire (AEQ; Brown, Christiansen, & Goldman, 1987) is a self-report questionnaire that tap youths' perception of positive and negative outcomes related to using alcohol. Because this intervention is designed to orient youth towards longer-term (rather than immediate) rewards, the investigators expect to see significant decreases in positive expectancies of alcohol use and an increase in negative expectations. The AEQ has been found to be reliable and valid indicators of adolescents' perceptions of use (Aarons et al., 2001; Brown et al., 1987). |

Change in Marijuana Effect Expectancies |
The Marijuana Effect Expectancy Questionnaire (MEEQ; Schafer & Brown, 1991) is a self-report questionnaire that tap youths' perception of positive and negative outcomes related to using marijuana. Because this intervention is designed to orient youth towards longer-term (rather than immediate) rewards, the investigators expect to see significant decreases in positive expectancies of marijuana use and an increase in negative expectations. The MEEQ has been found to be reliable and valid indicators of adolescents' perceptions of use (Aarons et al., 2001; Brown et al., 1987). |
