Abstract [en]
Introduction. – The Trauma Symptom Inventory-2 (TSI-2) is a broad-spectrum assessment instrumentdesigned to identify symptoms that can appear in the aftermath of potentially traumatic experiences.
Objective. – This study aimed to evaluate the external and internal validity of this newly reconstructedinstrument.Method. – In total, 696 individuals participated in the study, including 83 psychiatric outpatients. Participants answered the TSI-2, together with a trauma history questionnaire, and other questionnairesassumed to correlate with the different scales included in the TSI-2.
Results. – Validity was evaluated by correlations between the TSI-2 and the other instruments and bythe differences between clinical and non-clinical populations. Reliability was calculated by testinginternal consistency and test-re-test reliability. A confirmatory factor analysis (CFA) was computed totest the postulated four-factor structure. Cronbach’s alpha was found to be good and ranged froma = .77 to .91 and test-retest reliability was strong. Strong to satisfactory correlations were foundbetween the TSI-2 and the other instruments. The student sample scored significantly lower than theclinical group on all clinical scales. Sensitivity and specificity were calculated with different cut-offscores.
Conclusion. – Despite the CFA demonstrating a questionably good model of fit, most of the scales provedto be sound and the TSI-2 could be recommended as a broad-spectrum assessment instrument.
