[Cross-cultural adaptation and validation of the World Health Organization Health and Work Performance Questionnaire to Brazilian nurses].

Study aiming to cross-culturally adapt the instrument Health and Work Performance Questionnaire (HPQ) and evaluate the psychometric properties of the Brazilian version for nurses. The adaptation process followed the Process of Translation of World Health Organization. Data for the evaluation of the psychometric properties were collected in a teaching public hospital of Ribeirão Preto in 2011. The evaluated psychometric properties were: face validity and content (group of experts), reliability by Cronbach's alpha and test-retest stability. In the evaluation of psychometric properties, the internal consistency of the HPQ adapted version, Cronbach's alpha was 0.94 for the section A and 0.86 for section B of the instrument. In analyzing the agreement of test-retest stability, the agreements were positive and statistically significant. Thus, the HPQ adapted version proved valid and reliable in the sample studied.
