Outcomes
REGRESSION, SECONDARY
The prespecified primary outcome was the rate of moderate to severe distress (DT score ≥5) at a time frame of 24 weeks. For analysis, we transformed the weekly DT scores into a binary variable at the cutoff value of 5, constructed a panel data set with the binary outcome variable for 24 weeks, and then used a logit model with control variables. The prespecified secondary outcome was the total number of weekly step counts collected during 24 weeks. We constructed a panel data set with the weekly step counts for 24 weeks and then used a regression model with control variables.
