My Exposure to Violence: translation and cultural adaptation to the BR Portuguese

ABSTRACT OBJECTIVE To translate and adapt the My Exposure to Violence instrument for measuring exposure to community violence into Brazilian Portuguese. METHODS Psychometric study of translation and cross-cultural adaptation in seven stages: (I) initial translations, (II) synthesis of translations, (III) back-translations, (IV) cross-cultural pre-adaptation, (V) evaluation by committee of judges, (VI) pre-test, and (VII) submission to the original author. In step V eight judges evaluated the instrument’s equivalence of content, and the content validity index was calculated for each item (CVI-I) and for the average of the instrument (CVI-M), considering a CVI-I ≥ 0.78 as excellent and a CVI-M ≥ 0.80 as acceptable and ≥ 0.90 as excellent. The pre-test was conducted with 39 adolescents enrolled in an educational institution in Fortaleza, state of Ceará. The understandability of the items was evaluated. RESULTS In step I, two translations were produced with few differences between them. These were resolved in step II, by generating the synthesis version (T12). In step III, the back-translated items reflected the same content as the items in the original version. In step IV, T12 was revised by the authors, who made specific linguistic changes in order to facilitate understanding. In step V, one item (22) presented CVI
