WHAT THE TEST MEASURES

About This Assessment

Peritraumatic Distress Index Test

pandemic stress level

This self-report measure is designed to screen acute distress reactions occurring during or immediately after a stressful event. The Peritraumatic Distress Index is commonly used to characterize peritraumatic emotional, cognitive, and somatic symptoms that may warrant closer clinical attention.

The instrument includes 24 items and typically takes about 5 minutes to complete. Items ask respondents to rate the frequency or intensity of distress-related experiences, supporting a brief summary of current symptom burden for use in clinical screening or research contexts.

Originally described by Robert A. Bryant, Michel R. Weiss, and Alain Brunet, the Peritraumatic Distress Index can be used to monitor distress levels over time and to help identify individuals who may benefit from further evaluation, particularly in the context of public health emergencies or other high-stress circumstances.
