What is the highest possible score?
The total score ranges from 0 to 27, where each of the 9 items is scored from 0 (not at all) to 3 (nearly every day).
How often should I establish a baseline?
In research contexts, participants often complete the profile every two weeks to monitor shifts in intensity levels.
