Briere, J. (1995). Trauma Symptom Inventory (TSI): Professional Manual. Lutz, FL: Psychological Assessment Resources, Inc.
The TSI was developed to assess acute and chronic traumatic symptomatology in adults 18 years and older. The test consists of 100 items and is divided into 10 clinical scales and 3 validity scales.
4-point Likert-type rating scale: 0 (Never) to 3 (Often)
|Trauma Symptoms||Anxious Arousal||Not available|
|Trauma Symptoms||Depression||Not available|
|Trauma Symptoms||Anger/Irritability||Not available|
|Trauma Symptoms||Intrusive Experiences||Not available|
|Trauma Symptoms||Defensive Avoidance||Not available|
|Trauma Symptoms||Dissociation||Not available|
|Trauma Symptoms||Sexual Concerns||Not available|
The TSI manual states that "the TSI can be administered and scored by individuals who do not have formal training in clinical psychology" . . . "the interpretation of TSI scores and profiles requires graduate training in psychology."
The sample used to develop the TSI is the same sample that was used to norm the measure.
|Internal Consistency||Acceptable||Cronbach's alpha||0.74||0.91||0.86|
Items were selected according to the existing trauma literature, clinical experience, and consultation with trauma experts.
|Validity Type||Not known||Not found||Nonclincal Samples||Clinical Samples||Diverse Samples|
|Sensitive to Change||Yes|
|Sensitive to Theoretically Distinct Groups||Yes||Yes||Yes|
1. Wallis (2002) established sensitivity to change in an experimental study. After receiving group therapy, traumatized participants in the experimental group scored lower on 7 of the 10 clinical scales on the TSI and on the three composite scales. The researcher reported no similar reduction in symptoms in the control group.
Other studies showing tx sensitivity of TSI:

Traumatic Stress, 16, 337-340.

sexual abuse survivors within a clinical trial. CNS Spectrums, 8, 340-342, 351-355.
|Not Known||Not Found||Nonclinical Samples||Clinical Samples||Diverse Samples|
In a study with 449 participants from the general population, discriminant function analysis revealed that the TSI scales correctly predicted 24 of 26
PTSD positive cases (92% true positive) and 385 of 423 PTSD negative cases (91% true negative) (Briere, 1995).
1. No clinical population was used in the norming procedures.
2. There is no test-restest reliability reported for the measure.
3. Overall, the TSI is based on extensive research and shows good psychometric properties.
|Language:||Translated||Back Translated||Reliable||Good Psychometrics||Similar Factor Structure||Norms Available||Measure Developed for this Group|
|1. French (Canadian)||Yes||Yes|
The norming sample consisted of 77.5% Caucasian, 10.3% African Americans, 6.1% Hispanics, 2.9% Asians, and 2.3% Native Americans. Although the sample is generally comparable to the 1990 U.S. Census, the author noted that it slightly overrepresented Caucasian, married, and more educated individuals.
There are special norms for ethnic minorities (African American and Hispanics) for the three validity scales.
No special norms for ethnic minority groups for the clinical scales were warranted because only three of the 10 clinical scales showed any race differences, and overall, only 2% of the variance can be accounted for by race.
