Currently, stress has been a major challenge for the population, making it harmful to human health. Even in the face of technological advances, human beings continue to experience individual or social stressors which aggravate or lead to the development of chronic diseases. Therefore, quality of life can be affected by the occurrence of stressful events and the inability to adapt to them. Thus, it is essential to develop or improve instruments which assess emotional stress for using in research and health care practice. The current study aims to carry out the cross-cultural adaptation and validation of the instrument "Life Experiences Survey (LES)" from the Portuguese language of Portugal to the Portuguese language of Brazil allowing its use for analyzing stressful life experiences in the Brazilian population. Initially, the original instrument from Portugal will be adapted into Brazilian Portuguese. After the language adaptation, the questionnaire will be applied to volunteers (pre-test) to evaluate the degree of understanding of the instrument's items. After cross-cultural adaptation, the instrument will be applied to a new group of people to evaluate the psychometric measures. Afterwards, a re-test will be applied to the same group of volunteers for analyzing the understanding of each item of the instrument. Finally, the AAV questionnaire will be subjected to factor analysis to conclude its adaptation to the Brazilian Portuguese language. We hope that the development of the current study allow to adaptation of a new instrument for assessing of the emotional stress in the Brazilian population.
