Daily Diary Satisfaction Scores
5-item self-assessment measuring satisfaction with the daily dairy function of the RELAXaHEAD app. Items are ranked on a 5-point Likert scale, where: 0 = Strongly Disagree; 1 = Disagree; 2 = Neither Agree nor Disagree; 3 = Agree; and 4 = Strongly Agree.
The total score is the sum of responses. Scores range from 0-20; higher scores indicate higher levels of satisfaction.
