NCT06941181

Brief Summary

This study proposes to extend the ongoing longitudinal study of health risk behaviors and obtain new data from former adolescents (followed previously from ages 13-22; Times 1-8) now from ages 23 to 28 (Times 9-11). The goal of this study is to examine the contribution of developing neurocognitive markers to substance use in young adulthood by following a well-characterized longitudinal sample.

Outcome Measures

Primary Outcomes (1)

  • substance use behaviors

    Frequency (past year and past month use) of cigarette/tobacco, alcohol, cannabis, and other drug use will be asked.

    Approximately every 18 months, 3 times across 5 years

Study Arms (1)

neurocognition

Other: neurocognitive tasks

Interventions

1. risk-processing: Participants choose between two choices across 72 trials of a forced choice decision-making neurocognitive task (Holt and Laury, 2002). Each trial included a high and low monetary outcome with an associated probability of occurring. Each choice option is shown as a pie with ten slices represented probabilities, in which each piece corresponded to ten percent. 2. cognitive control: A multi-source interference task (MSIT; Bush et al., 2003) is used in which participants are presented with three digits and asked to identify the digit different from the others. In the neutral condition, the target's identity is congruent with its relative position. In the interference condition, the target's identity does not match its relative position. There are a total of 96 neutral trials and 96 interference trials.
