Abstract

This study aims to translate and validate Early Trauma Inventory Self Report - Short Form (ETISR-SF) to Brazilian Portuguese. 253 adult subjects answered the ETISR-SF, Beck Anxiety Inventory (BAI), Fagerstrom Test for Nicotine Dependence (FTND), Patient Health Questionnaire (PHQ-9) and Fast Alcohol Screening Test (FAST). The instrument showed good internal consistency (0.83). Correlations with the PHQ-9 and BAI were moderate (r=0.26-0.47) and showed the expected associations with psychiatric constructs. No associations were found for FTND and FAST. Confirmatory Factor Analysis revealed that a correlated four-factor model as well as a second order model subsuming four lower order components presented the best model fit. Test-retest reliability was also excellent (ICC=0.78-0.90). ETISR-SF is suitable for assessing traumatic experiences in a Brazilian community sample. Given the importance of trauma as a public health problem, tools such as ETISR-SF may help clinicians/researchers to better evaluate and measure such events and further advance clinical care of trauma victims.
