Abstract
We measure physical activity, time use, and well-being in a sample of college students that we have been following since February 2020. Participants received wearable trackers that monitored their physical activity and sleep before and during the Covid-19 pandemic. Participants also filled out surveys aimed at capturing their time use and mental health. We find substantially higher rates of depression and anxiety following the onset of the pandemic. The rise in depression is greater among students with larger changes in lifestyle during the pandemic, especially among those with greater declines in physical activity. In this study, we will attempt to increase physical activity by randomly assigning students to receive incentives to walk, and test the effect of this intervention on mental health.

Experimental Details

Interventions

Intervention(s)
Starting on June 1st, participants will be randomized to receive incentives to walk 10,000 steps per day over the course of 2 weeks.
Intervention Start Date
2020-06-01
Intervention End Date
2020-06-15

Primary Outcomes

Primary Outcomes (end points)
Physical Activity (steps and active minutes), Depression (as measured with the CES-D scale). We will examine treatment effects by pre-intervention depression and pre-intervention change in physical activity.
Primary Outcomes (explanation)
Active minutes will be the total number of non-sedentary minutes as detected by the Fitbit.
We will construct a dummy variable with CES-D scores greater than15 to indicate participants at risk of depression.

Secondary Outcomes

Secondary Outcomes (end points)
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
•Control: participants will wear an activity tracker (Fitbit) and fill out surveys about time use and mental health.
•Treatment: participants will wear an activity tracker (Fitbit) and will receive $5 for each day in which they complete 10,000 steps. They will fill out surveys about time use and mental health.
Experimental Design Details
Randomization Method
Randomization done in office by a computer, blocking on pre-intervention depression levels (in May) and pre-intervention changes in physical activity.
Randomization Unit
individual
Was the treatment clustered?
