MELLO, Marcelo Feijó de et al. Early Trauma Inventory (ETI): cross-cultural adaptation and internal consistency. Cad. Saúde Pública [online]. 2010, vol.26, n.4, pp.713-724. ISSN 1678-4464. http://dx.doi.org/10.1590/S0102-311X2010000400014.
Early life stress is a strong predictor of future psychopathology during adulthood. The Early Trauma Inventory (ETI) was developed to detect the presence and impact of traumatic experiences that occurred up to 18 years of age. The ETI was translated and cross-culturally adapted and had its consistency evaluated. Victims of violence that met the inclusion and exclusion criteria were submitted to SCID-I and ETI. Ninety-one patients with post-traumatic stress disorder (PTSD) were included. Cronbach's alpha in the different domains varied from 0.595 to 0.793, and the total score was 0.878. Except for emotional abuse, most of the various domains displayed inter-item correlation rates of 0.51 to 0.99. The adapted version was useful for clinical and research purposes and showed good internal consistency and inter-item correlation. The ETI is a valid instrument with good consistency for evaluating history of childhood and adolescent trauma in adults.
