Only participants who completed the baseline questionnaire at least to the point where they indicated their three personal goals were able to continue participating in the study.

Study Part 3 Participants received three daily and an additional fourth (evening) questionnaire over a three-week period (from 02 May 2022 to 22 May 2022). Daily questionnaires could be opened for up to 60 minutes after receiving the notification and took about 2 – 3 minutes to complete. Completion of the evening questionnaire took about 4 – 5 minutes. Participants were instructed to complete the evening questionnaire before going to bed. The evening questionnaire could be opened for up to eight hours after the notifications were sent.
