Abstract

INTRODUCTION: The Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE) is a widely-used scale, and the first to include a dimensional approach to understanding schizotypy.

OBJECTIVE: To adapt the short version of the O-LIFE (O-LIFE-S) into Brazilian Portuguese.

METHOD: a) Two independent bilingual professionals translated the original instrument into Brazilian Portuguese; b) a third bilingual professional summarized the two translations; c) a fourth bilingual expert translated the Portuguese version back into English; d) this back-translation was adjusted by a committee of psychology experts; e) a pilot study was conducted with 10 participants from the general population.

RESULTS: O-LIFE-S was considered ready to be used in a formal validation study in Brazil.

CONCLUSION: The scale appears to cover the dimensional approach to schizotypy. However, a future validation study needs to be conducted to determine the internal consistency and reliability of the Brazilian Portuguese version of the O-LIFE-S .
