About

This project will first examine nature opportunities, belonging and benefits with a multi-state nature-based intervention with a focus on students of color. In light of the syndemic, 'nature deficit disorder' and poor mental health, the investigators anticipate several far-reaching impacts that will (a) test a nationally useful standardized way to quantify exposure; (b) invest in nature resources and accessibility on campuses; and (c) promote the mental health and therapeutic benefits of nature among young adults. These will lead to understanding the nature exposure and mental health interplay and techniques for quantifying and encouraging nature exposure to treat the on-going youth mental health crisis. Including HBCUs and an hispanic-serving institution is expected to result in heightened visibility of underlying disparities, including structural racism and land-based violence and discrimination, that have contributed to current-day nature gaps and dismantled nature relationships for students of color.

Full description

America faces a syndemic of youth 'nature deficit disorder' and poor mental health. These conditions can be improved by nature contact, but the outdoors is not equally accessible, particularly for students of color. This study leverages the NatureDose™ app to identify racial/ethnic inequities in nature opportunities, belonging, and benefits and conduct an RCT to improve mental health and address disparities by getting university students outdoors into nature. The investigators will test 3 over-arching questions:

1. Are there differences in nature opportunities and/or belongingness for White versus students of color?
2. Does more time in nature correlate with greater feelings of nature connectedness, belongingness, and better mental health?
3. Is a nature-based intervention that leverages NatureDoseTM a cost-effective way to improve mental health, particularly for students of color?

This project has two stages. 1) We will determine nature opportunities at each institution using park and sports field mapping, remote sensing, and tree canopy assessment within 30 miles of campuses to identify disparities. 2) As Fall semester starts, we will recruit 160 students/site for a randomized controlled trial (N=1,440 total, giving 80% power to detect effects down to Cohen's d=0.2 even with attrition). Students will complete baseline surveys on nature connectedness (NR-6), nature belongingness (validated scale for university students), mental health (distress, worry, positive/negative affect), and demographics. Next, students will download the NatureDose™ app, which uses 30+ datasets and machine learning models to quantify nature. The app calculates how much nature is near users whenever they are outdoors, and weekly minutes in nature. App data will be collected over a 2-week baseline period, after which students will be randomized to receive 1) standard information about the health benefits of nature (50%) (Active Control) or 2) standard health information, a request to increase weekly minutes in nature, eligibility for a prize, and peer performance comparison. After 2 weeks, students will repeat baseline surveys.
