The Quick Inventory of Depressive Symptomatology (16-Item) (Self-Report)
Thank you for taking the time to answer each question.
The QIDS-SR is not designed to diagnose depression, but rather to assess the severity of symptoms of a person who has been diagnosed as having depression by a clinician. In general the scores are most helpful in tracking changes in the severity of symptoms, for example, as a result of treatment. However, the scores can give a broad estimate of the overall severity of a depressive illness.
Total QIDS-SR scores range from 0 to 27. This is not the total of the scores for all 16 questions, but rather it is the sum of the highest score from groups of questions (e.g. the four that relate to sleep problems). In general:
- Scores of 5 or lower are indicative of no depression
- 6 to 10 indicate mild depression
- 11 to 15 moderate depression
- 16 to 20 severe depression
- Scores greater than 21 indicate very severe depression.
This said, severity is best judged by taking the who picture of severity of symptoms and impact of the illness on the individual, rather than QIDS score alone.
