NCT04642235

Brief Summary

The investigators pilot test two intervention strategies to increase green space use- place-based and person-based, as well as evaluate the dose-response relationship between green space use and health.

Study Arms (4)

Nature Nook

EXPERIMENTAL

Nature Nook builds on our prior work with a standard vacant lot greening intervention involving: removing trash, grading the land, planting new grass and trees, installing a low wooden perimeter fence, and regular maintenance. This greening intervention was designed as a blight removal strategy. People in this arm receive no intervention.

Other: Nature Nook

Nature Coach

EXPERIMENTAL

The Nature Coach intervention, developed in a prior study (NCT04146025), will be delivered to people in their homes. Participants will live in the blocks immediately surrounding the study vacant lots randomized to this arm. The lots in this arm receive no intervention.

Behavioral: Nature Coach

Nature Nook + Nature Coach

EXPERIMENTAL

This is a combined arm: a place-based intervention (Nature Nook) and a person-based intervention (Nature Coach).

Other: Nature Nook + Nature Coach

Control

NO INTERVENTION

The study lots randomly selected for this arm, as well as the participants living near them, receive no intervention.

Interventions

Nature NookOTHER

The Nature Nook intervention will take place on lots that already have the standard greening intervention. In addition, design elements will be added such as a simple path and benches to explicitly invite people into the space. An additional difference is the exclusive use of larger, corner lots, rather than smaller mid-block spaces, to maximize visibility.

Nature Nook
Nature CoachBEHAVIORAL

The Nature Coach Intervention consists of 3 components - home visit, text message follow up, and goal feedback. Home visit. During the 1-hour home visit, the coach will (a) provide education about the health benefits of nature, (b) identify nearby nature targets for the participant to visit, (c) complete a pre-commitment contract based on individualized weekly nature goals, and (d) brainstorm barriers and solutions to reaching the goals. Personalized weekly text messages. Texts will serve as reminders of goals set with the Nature Coach, as well as encouragement to meet the goals. The context of text messages with change slightly based on individual participants, the goals they set, and the barriers they identify. Goal feedback- At the end of each week, participants will receive a progression badge via text message that shows the amount of days and time they spent in nature, and how this matched up to the goal set with the Nature Coach.

Nature Coach
Nature Nook + Nature CoachOTHER

The combined intervention will involve the installation of Nature Nooks to blighted vacant lots followed by the delivery of the Nature Coach intervention to people living in the immediate surrounding blocks. The intervention will be tailored to explicitly direct participants to use the Nature Nook.
