This research aims to deliver a computer-based working memory training program to improve delay discounting DD and prevent substance misuse among at-risk adolescents aged 11 to 15 years in underserved communities. The study focuses on youth exposed to early adversity, who are at higher risk for substance use and related health problems. Researchers want to understand how changes in DD might reduce substance misuse and inform future prevention strategies in similar communities. Participants will be randomly assigned to one of two groups an active working memory training program or a control computer training that does not engage working memory. Each participant will complete at least 10 sessions, with each session lasting about 30 minutes, over 5 to 8 weeks. The active training includes tasks involving recalling sequences of digits and words in both auditory and visual formats, while the control group completes similar tasks designed not to target working memory. During the study, researchers will assess participants at baseline, 2 weeks, and 3 months using various tests and questionnaires measuring delay discounting, future thinking, memory, impulse control, risk behavior, and substance use expectations. Participants will also be monitored for their ability to receive and send study-related text messages. The study includes follow-up periods to evaluate changes in behavior and cognitive function related to substance use risk, with total participation lasting up to three months post-intervention.
