WHAT THE TEST MEASURES

About This Assessment

PTSD Therapeutic Change Questionnaire Test

ptsd

Ongoing monitoring of posttraumatic stress symptoms can support clinical decision-making across the course of care. The PTSD Therapeutic Change Questionnaire is a brief measure intended to quantify perceived change in PTSD symptom severity over time.

It consists of 8 items and typically requires about 2 minutes to complete. It is used to support repeated assessment of treatment response and to inform adjustments to the treatment plan when clinically indicated.

The PTSD Therapeutic Change Questionnaire was developed by Colket and Davidson (1997) and is designed for use in routine clinical follow-up rather than as a stand-alone diagnostic instrument.
