NCT06242704

Brief Summary

The goal of this clinical trial is to deliver a computer-based working memory training program to improve delay discounting (DD) and prevent substance misuse among at-risk adolescents in a traditionally underserved area. Results from the study will inform future substance use prevention efforts targeted at youth exposed to adverse childhood experiences. Findings will also refine future models of intervention delivery in traditionally underserved communities. The main aims of the project are are: 1\) To examine to examine changes in hypothesized mechanisms of substance use initiation and escalation, and 2) to assess whether changes in DD are a mechanism for reducing substance misuse during early adolescence. The investigators will evaluate whether changes in DD following active treatment predict substance use outcomes over the three-month follow-up period.

Outcome Measures

Primary Outcomes (1)

  • Change in Monetary Choice Questionnaire

    The Monetary Choice Questionnaire (MCQ) is a measure of delay discounting (DD). Participants will be presented with two choices, one with a small, immediate monetary reward and the other with a larger, delayed monetary reward. They will be required to choose one of those rewards and their responses will be scored using reference discounting curves. A calculated score that places participants on steeper curves indicates higher levels of impulsivity and higher rates of DD. Scores are not bounded with a minimum and maximum value, but higher scores indicate worse outcomes and demonstrate the participant's preference to gain smaller rewards immediately over larger rewards with a time delay.

Working Memory Training

EXPERIMENTAL

The intervention is a computer-based training aimed at improving working memory in order to decrease delay discounting. Active training sessions include: Sequenced Recall of Digits - Auditory, Sequenced Reverse Recall of Digits - Auditory, Sequenced Recall of Digits - Visual, Sequenced Reverse Recall of Digits - Visual, Sequenced Recall of Words - Auditory, Sequenced Recall of Words - Visual, Sequenced Reverse Recall of Words - Auditory, Sequenced Reverse Recall of Words - Visual. Participants will complete at least 10 sessions with each session taking approximately 30 minutes to complete.

ACTIVE COMPARATOR

The comparison control condition is a multi-session control computer training condition that is designed to not engage working memory during computer-based engagement sessions: Sequenced Recall of Digits - Auditory, Sequenced Reverse Recall of Digits - Auditory, Sequenced Recall of Digits - Visual, Sequenced Reverse Recall of Digits - Visual, Sequenced Recall of Words - Auditory, Sequenced Recall of Words - Visual, Sequenced Reverse Recall of Words - Auditory, Sequenced Reverse Recall of Words - Visual. Participants will complete at least 10 sessions with each session taking approximately 30 minutes to complete.
