I think it would be helpful to show a scale (for reference on the webpage) ranging from 1 through 10 with a word or phrase applied to each number to help patients better pin point their moods. For example, 5 = average, being neither up nor down ... 8 = good, 9 = very good, 3 = poor, 1 = very bad, etc. This might help all participants to be more on the same page, sort of standardize the patients' mood numeric values.
