Symptom Checklist-90 (SCL90)

The Symptom Checklist-90 (SCL90) is a 90-item questionnaire used to assess psychological problems. The Symptom Checklist-90-Revised (SCL90R) is the revised version of the questionnaire. The revised version is almost identical (2 questions with slightly different wording), but the main difference is that the SCL90R is not available on the public domain.

ITEM CODING

Each item is scored on a scale from 0 to 4 based on how much an individual was bothered by each item in the last week:

0 = Not at all

1 = A little bit
