Clinical norms, reliability and validity for the hopkins symptom checklist-21

Abstract
The Hopkins Symptom Checklist-21 (HSCL-21) was administered to 141 psychotherapy clients attending for their first visit at an outpatient psychology department. Some preliminary normative data is provided along with support for the reliability and validity of the HSCL-21 with a clinical sample. The HSCL-21 showed sensitivity to change over the course of psychotherapy. Due to its brevity, it may be preferable to longer symptom-distress measures for repeated measurement in monitoring, client progress over therapy.
