FostrSpace-CASA R61/R33 Study for Substance Use

This study is looking at how an online app called FostrSpace can help reduce substance use in young people (ages 13-20) who are in foster care. It will also train CASA volunteers (Court Appointed Special Advocates) on how to use FostrSpace and refer youth to it. You can join if you are between 13 and 20 years old, speak English, have a CASA worker, and have a device with internet access. CASA volunteers aged 18 and over, assigned to a youth in this age range, can also participate. The study will measure success by looking at rates of drug and cigarette use at the beginning of the study. The current recruitment status is unclear, and the study plans to enroll 400 participants.

Study design
This is an interventional study, meaning participants will receive specific interventions. It aims to enroll 400 participants, including both youth and CASA volunteers.
What's involved
Participants will either receive six training sessions on ECHO-FostrSpace or one informational session on ECHO-FostrSpace. The record does not specify how long these sessions are or any other procedures.
Compensation
Not stated in the trial record.
Follow-up
The study measures drug and cigarette use at baseline (the beginning of the study), but it is not specified if or for how long participants are followed after this.
