^aβ₀ denotes average baseline value on day 1, where minimum possible score is 1 (strongly disagree) and maximum possible score is 7 (strongly agree).

^bβ₁ denotes change in scores between the weeks when the POWeR Tracker app was and was not available where the magnitude of change may be different for each participant.

^cσ_ou denotes standard deviation from average baseline value on day 1.

^dσ_1u denotes standard deviation of random effects for changes in scores between the weeks when the POWeR Tracker app was and was not available.
