Feasibility of Collecting Stress Biomarkers Among Youth Experiencing Homelessness

The study will examine changes in acute stress (biological and psychological) via salivary cortisol and alpha amylase levels as well as survey measures of self-reported anxiety in response to either (a) a free online guided mindfulness meditation available at (https://www.uclahealth.org/marc/mindful-meditations); (b) a guided mindfulness meditation via virtual reality (https://guidedmeditationvr.com/) or (c) a virtual reality platform of historic photographs and written narratives (https://lookingglassvr.com/). Participants will also complete an interviewer administered survey to measure sociodemographic factors, mental and physical health status, substance use, and medication use and provide a hair sample to measure cortisol.
