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), Fagerström 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.

Highlights

Traumatic experiences are highly prevalent [1,2] and constitute risk factors for atypical development [3]
B Beck Anxiety Inventory (BAI) - developed by Beck and Steer [25] and translated, adapted, and validated for the Brazilian Population by Cunha [26]
The translated version of the scale showed to be reliable in terms of both internal consistency and test-retest, showed an expected correlation with scores of emotional psychopathology and a factor structure that fits the original propositions

Summary

Introduction

Traumatic experiences are highly prevalent [1,2] and constitute risk factors for atypical development [3] They have a significant impact on the biological, social emotional and cognitive functioning of the individual, and favor the emergence of psychiatric disorders, whether in infancy or in adulthood [3,4,5,6,7,8]. The Early Trauma Inventory Self Report – Short Form (ETISR-SF) was originally proposed by Bremner et al [18] It is comprised of 27 items, divided into four dimensions (general trauma, physical abuse, emotional abuse and sexual abuse) and scored on a dichotomous scale (Yes/No). The aim of the present study was to translate and validate the Early Trauma Inventory Self Report – Short Form (ETISRSF) scale for the Brazilian context, studying the following psychometric properties: internal consistency, concurrent/ divergent and discriminative validity, factor structure, and testretest reliability
