The PHQ-8 is an eight item self-reported measure of depression. Each item is rated on a scale ranging from 0 (not at all) to 3 (nearly every day). Total score is the sum of individual eight items and ranges from 0 to 24, with higher scores indicating more severe depression symptoms. Total score of 0 to 5 indicates none to minimal depression, 6 to 10 indicates mild depression, 11 to 15 indicates moderate depression, 16 to 20 indicates moderately severe depression and 21 to 24 indicates severe depression.
