How to calculate scores?
Total scores for depression, anxiety, and stress symptoms are calculated by summing up the scores of each items, multiplied by factor two.
We classified patients into mild, moderate, severe, and extremely severe conditions of depression, anxiety, and stress symptoms based on the total score within each subdomain. Depression scores were classified as: normal (0-9), mild (10-13), moderate (14-20), severe (21-27), and extremely severe (27+). Anxiety score was classified as: normal (0-7), mild (8-9), moderate (10-14), severe (15-19), and extremely severe (20+). Stress score was classified as: normal (0-14), mild (15-18), moderate (19-25), severe (26-33), and extremely severe (34+).
