Seventeen of the 90 items on the Symptom Checklist-90 were found to have some value in predicting whether or not the person would relapse in the subsequent 6 months.
These symptoms can be categorized as related to depression, anxiety, or psychological vulnerability.
From these 17, a set of 12 symptoms was identified that had the greatest ability to predict relapse versus non-relapse.

- 6% when none of the 12 symptoms were present
- 17% when 1 to 5 symptoms were present
- 34% when 6 to 9 symptoms were present, and
- 73% when 10 or more of these 12 symptoms were present.
