Trauma symptom inventory

The Trauma Symptom Inventory (TSI) is a Psychological evaluation/assessment instrument that taps symptoms of Posttraumatic stress disorder and other posttraumatic emotional problems. It was originally published in 1995 [1] by its developer, John Briere. It is one of the most widely used measures of posttraumatic symptomatology.[2]

The TSI is relatively unique in comparison to other measures of posttraumatic symptomatology, in that it is a multi-scale instrument, including 10 scales of various forms of clinical psychopathology related to psychological trauma. Also unique, it has three validity scales in order to assess the trauma victim's test-taking attitude, such as overreporting, underreporting and inconsistency; however, research demonstrates that the TSI does not achieve excellent accuracy in detecting the Malingering of posttraumatic stress disorder from genuine PTSD.[3]

Original psychometric data on the TSI demonstrated adequate internal consistency (alphas ranging from .84 to .87).[4] Validity with a civilian trauma-exposed sample has been demonstrated, with substantial relationships found between the TSI's clinical scale scores and other established measures of PTSD.[5] Further corroboration of the TSI's psychometric properties, with trauma-exposed military veterans, was recently documented.[6]

More recently, a second edition of the TSI was published (TSI-2),[7] with limited research investigating its performance thus far.[8]
