Trauma Symptom Inventory-2 (TSI-2)


Trauma Symptom Inventory-2 (TSI-2)

Briere, 2011


The TSI-2 is a 136-item adult self-report measure of posttraumatic stress and other psychological sequelae of traumatic and stressful events. It was updated in 2011 from the original 100-item TSI and designed to assess sequelae of a wide range of adversities, including DSM-5 trauma but also stressful experiences such as emotional neglect and experiences of loss. The TSI-2 assesses PTSD symptoms but also broader psychological outcomes. Symptom responses are not tied to a particular event or timespan. Respondents are asked to rate how often each symptom has happened to them in the past 6 months. Items are rated on a 4-point frequency scale ranging from 0 ("never") to 3 ("often").

The TSI-2 has 12 clinical scales (some with subscales) that assess a variety of symptom domains related to trauma:

  • Anxiety, Intrusive Experiences
  • Defensive Avoidance
  • Dissociation
  • Insecure Attachment
  • Impaired Self-Reference
  • Depression
  • Suicidality
  • Sexual Disturbance
  • Tension Reduction Behavior
  • Anger
  • Somatic Preoccupation

Therefore, scales map onto some DSM-5 PTSD symptoms (e.g., avoidance, intrusions) but the TSI-2 is not designed to map solely or directly onto DSM-5 PTSD. The TSI-2 also includes 2 validity scales (response level and atypical response) along with 8 critical items to help identify potential severe disturbance or danger (e.g., suicidal ideation). The TSI-2 includes a reliable change score for repeated measurement as well. A computer scoring program is available from the test publisher, with norms based on gender and age. The TSI-2 is recommended for measuring a variety of trauma-related symptoms in clinical or research settings.


The 126-item TSI-2-A is an alternative version that does not contain any sexual symptom items.
