A Randomized Clinical Trial of a Novel Drug Education and Diversion Program (iDECIDE) for Middle and High School Students
Purpose
The primary goal of this study is to test the effectiveness of the iDECIDE (Drug Education Curriculum: Intervention, Diversion, and Empowerment) curriculum, a novel drug education and diversion program, in approximately 300 middle and high school students, who have violated their school substance use policies in the past month, as an alternative to punitive school responses for school-based substance use infractions. This randomized controlled trial will test the hypothesis that adolescents randomized to the iDECIDE curriculum will have improved substance use outcomes (i.e., knowledge, attitudes, and behavior) compared to adolescents in a waitlist control group. The outcomes of this study will measure knowledge of drug effects and brain development, perceptions of harm from substance use, willingness to quit or reduce use, and substance use behavior.

- Parallel Assignment
- Intervention Model Description
- Approximately 300 participants will be enrolled into a two-arm, assessor-blind, randomized controlled trial to compare substance use outcomes (i.e., knowledge, behavior, and attitudes) across a one-year follow-up period in adolescents randomly assigned to the iDECIDE drug curriculum or the waitlist control group.

- Masking
- Double (Investigator, Outcomes Assessor)
- Masking Description
- Eligible participants will be randomly assigned at the end of the baseline visit in a 1:1 ratio, in blocks of 6, to either a waitlist control group or the iDECIDE curriculum group. Randomization will be stratified by substance use frequency. Treatment will be assigned according to study number, assigned sequentially to eligible participants who enroll in the trial and attend the baseline visit. Investigators and outcome assessors will be fully blinded to allocation across the two arms. Facilitators of the iDECIDE curriculum will not be involved with the data outcome assessments.
Arm Groups
| Arm | Description | Assigned Intervention |
|---|---|---|
|
Experimental iDECIDE |
Participants will... 1. Receive 4 weekly sessions of the iDECIDE drug curriculum. 2. Complete assessments and questionnaires, including self-reports of substance use and 4 urinalysis virtual visits. 3. Be video recorded for quality control. |
|
|
No Intervention Waitlist Control Group |
Participants will... 1. Not receive the iDECIDE curriculum during the weekly visits. They can choose to self-enroll in the iDECIDE curriculum at their one-month follow up visit. 2. Undergo symptom monitoring during the weekly visits. 3. Complete assessments and questionnaires, including self-reports of substance use and 4 urinalysis virtual visits. |

Detailed Description
This study will be a two-arm, assessor-blind, randomized controlled trial enrolling approximately 300 middle and high school students who have recently violated a school substance use policy. Participants will be followed over a one-year period. Participants will be randomly assigned to either four-weeks of iDECIDE or a waitlist control group. Participants assigned to receive iDECIDE will receive a drug education curriculum developed to provide behavioral support and psychoeducation via videoconference or in-person visits. The purpose of iDECIDE is to provide students with the knowledge and skills they need to make healthy decisions regarding substance use. Participants in the waitlist control group will undergo symptom and substance use monitoring only, until completion of the one-month follow-up visit at which point they will be offered the opportunity to enroll in the iDECIDE curriculum, if desired. Data collection will occur during nine visits over the span of approximately one year, including one randomization baseline visit, four weekly visits during the intervention phase of the study during which time participants will participate in either iDECIDE or monitoring, and then four follow-up visits. The follow-up visits will occur at approximately one week, one month, six months, and one year following the end-of-intervention. Participants in both arms will complete questionnaires and assessments conducted by raters blinded to study arm assignment. Primary outcomes (knowledge of drug effects, knowledge of brain development and neurobiology of addiction, readiness to quit, perceptions of harm, and frequency of substance use) will be assessed at visit 1 (baseline), visit 5 (end-of-intervention), visit 6 (one week follow-up), and visit 7 (one month follow-up). Participants will be compensated for session attendance and provision of urine samples.
