The primary aim of this study is to examine whether lower-risk activities displace participation in higher-risk behaviors during COVID-19. Investigators will test this aim by promoting specific activities that are expected to be low-risk when it comes to COVID-19 transmission and assessing impacts on participants' activity choices.
There will be two study groups, Group 1 and Group 2, each of which will complete 3 online surveys and will be provided with information on lower-risk activities to do during COVID-19. Random assignment to groups will occur after the completion of a baseline survey. Group 1 will receive free access to a local hiking challenge after completing their baseline survey and an information sheet with current CDC-recommended activities after post-test. Group 2 will receive the same resources, but in the opposite order. Therefore, surveys administered at midpoint (\~6 weeks) and post-test (\~12 weeks) will allow for a test of the effects of providing access to the hiking challenge on outcomes of interest.
If participants choose to sign up for the hiking challenge, they receive a list of local hikes/nature walks, accompanying maps, scavenger-hunt-like activities (finding a certain landmark on each hike), and the opportunity to earn prizes and engage with other hikers on social media. The primary outcome will be the activities in which participants engage. An adapted version of the Pleasant Activities list (Koks) will be used to assess activities participants have engaged in during the past 30 days at baseline, midpoint (\~6 weeks), and post-test (\~12 weeks). Current CDC guidance will be used to code activities as lower- and higher-risk anticipating the creation of an aggregate frequency of activities in each of the following categories: activities done outdoors alone or with members of the household (lower risk), activities done indoors alone or with members of the household (lower risk), activities done outdoors with others not in one's household (moderate risk), and activities done indoors with others not in one's household (higher risk). Adults' participation in different types of activities will also be summarized generally, in addition to specific activities of interest (e.g., the lower risk activities that are being targeted, like hiking; and activities that have received attention as being particularly higher risk, like indoor restaurant dining). Investigators will also examine impacts of the provision of the hiking challenge on secondary outcomes, including reported stress and sleep.
The study has the potential to shed light on displacement of higher-risk activities through promotion of lower-risk activities that could serve as substitutes. It also allows for an assessment of the impacts of the local hiking challenge on aspects of well-being. The first cohort of data collection for this study took place between January 2021-April 2021. A replication study was conducted in January 2022-April 2022. The details of the replication study were nearly identical, with one change being the provision of hiking equipment valued at \~$25 (microspikes for the Hiking Challenge intervention group and hiking socks for Activity List controls/the delayed intervention), a modification made based on barriers reported in the original study.
