Read the detailed description
The goal of this clinical trial is to identify gaps in substance use prevention across existing CASA trainings and the FostrSpace app for foster youth and test how substance use trainings for CASA volunteers could help facilitate FostrSace app referrals to reduce and prevent substance use among CASA youth.

What is being measured
The primary outcome is the main question the study is designed to answer.
Rate of Drug Use
The Texas Christian University (TCU) drug screen with opioid supplement is used to gather detailed information about drug and opioid use.
Measured: baseline
Rate of Cigarette Use
The Cigarette smoking and vaping/e-cigarette use is used to gather detailed information about nicotine and/or cannabis use.
Measured: baseline
Secondary outcomes (4)
The Alcohol and Marijuana Expectancy Questionnaire
The Alcohol and Marijuana Expectancy questionnaire is used to measure positive and negative expectancies about affective, cognitive and behavioral effects of alcohol and cannabis use. Items are rated from 1-5 scale and higher scores indicate negative alcohol and marijuana expectancies.
Measured: baseline
The Brief Young Adult Alcohol Consequences Questionnaire
The Brief Young Adult Alcohol Consequences Questionnaire is used to assess the severity of alcohol consumption. Higher scores indicate greater severity of consequences associated with alcohol consumption.
Measured: baseline
The Brief Marijuana Consequences Questionnaire
The Brief Marijuana Consequences Questionnaire is used to assess the severity of marijuana consumption. Higher scores indicate greater severity of consequences associated with marijuana consumption.
Measured: baseline
The Brief Symptom Inventory
Brief Symptom Inventory is used to measure depression, anxiety and somatization symptoms to assess for psychiatry distress. Index ranging from 0 to 72 with cut-score of 11 as indication of psychiatric distress.
Measured: baseline
