The content and information provided in the Check-in With Yourself tool is based on research involving thousands of young adults. The following outlines the sources for specific information presented in the tool:
Mood, Emotions, Loneliness, and Optimism:
Statistics were compiled from two large studies of young adults initially recruited in Washington State. Data included 934 people between the ages of 20-29 (including those in college and not in college) and were surveyed in 2020 and 2021. All studies were conducted by the Center for the Study of Health and Risk Behaviors and include Project Transitions and Project SAM.
Alcohol Use & Non-Use:
These statistics come from the CDC’s Behavioral Risk Factor Surveillance System (BRFSS). We include data specifically from 7,193 young adults (ages 18-29) in Washington State between 2016 to 2021. BRFSS completes more than 400,000 adult interviews each year across all 50 states, as well as the District of Columbia and three US territories, making it the largest continuously conducted health survey system in the world.
Marijuana Use and Non-use:
Statistics related to marijuana use come from the Washington State Young Adult Health Survey (YAHS). This annual survey began in 2014 and surveys young adults in Washington State about their use (or non-use) of alcohol, marijuana, and other substances. Each year, a new sample of 18-25 year olds is recruited, and each previous cohorts of young adults are resurveyed. For the statistics found in this program, we include all young adults between the ages of 18-29 (6,946) that were surveyed in 2021
