iDECIDE Program for Middle and High School Students with Substance Use Violations

This study is testing a new program called iDECIDE for middle and high school students who have recently violated school rules about substance use. iDECIDE is a 4-session program that teaches about how drugs affect the brain, industry tactics, and healthy ways to cope. The goal is to see if iDECIDE helps students improve their knowledge about drugs, change their attitudes, and reduce substance use compared to a group that doesn't receive the program right away. About 300 students will participate. To join, you must be in middle or high school, be between 9 and 22 years old, and have had a school substance use violation in the past month. If you are under 18, a parent or guardian must give permission. The study's current recruitment status is unclear.

Study design
This study is a randomized controlled trial with about 300 middle and high school students. Participants will be randomly assigned to either the iDECIDE program or a waitlist control group.
What's involved
You would have nine visits over about one year. This includes a baseline visit, four weekly visits for the program or monitoring, and four follow-up visits.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for approximately one year after the intervention, with visits at one week, one month, six months, and one year.

  • Knowledge of Drug Effects and Brain DevelopmentBaseline to 1-month follow-up (primary), 6-month and 1-year follow-up (exploratory)

    Knowledge of drug effects and brain development will be measured with a multiple choice questionnaire that assesses knowledge taught in the iDECIDE curriculum, including neurobiology of addiction, side effects of substance, and industry tactics to market substances to young audiences.

  • Frequency of Substance UseBaseline to 1-month follow-up (primary), 6-month and 1-year follow-up (exploratory)

    The Timeline Follow-Back (TLFB) will be used to measure number of days the participant used a substance, which substances were used, and the frequency of which substances were used. The initial TLFB at the baseline visit will measure substances used in the past 90 days, while the interim TLFB will measure substances used since each subsequent visit. Participants will also provide a urine sample at study visits 1, 5, 6, 7 to qualitatively screen for substances including amphetamines, cocaine, barbiturates, methamphetamines, benzodiazepines, opiates, marijuana, phencyclidine, propoxyphene, and methaqualone using a urine 10-panel. There will also be an assay to quantitate levels of cotinine and creatinine-adjusted carboxy THC at baseline, end-of-intervention, one-week follow-up, and one-month follow-up. The primary outcome will be change in frequency of past week use (number of days) for the substance used most frequently at baseline.

  • Readiness to Quit or Reduce Substance UseBaseline to 1-month follow-up (primary), 6-month and 1-year follow-up (exploratory)

    Participants will complete a Readiness Ruler to determine how ready they are to reduce their substance use on a scale from 1 (not at all ready) to 10 (very ready).

  • Perceived Harm of Substance UseBaseline to 1-month follow-up (primary), 6-month and 1-year follow-up (exploratory)

    The Perceived Harm of Substance Use measure was modified from the 2010 National Survey on Drug Use and Health. Participants will assess their perceived harm of various forms of substance use using four response categories that range from no risk to great risk.
