This article aims to describe the construction and validation of a questionnaire designed to investigate students' conceptions about human genetic engineering and eugenics. The instrument was built upon the type of Likert scale, in which the respondent manifests his degree of agreement with a set of assertions. In order to validate it as a research instrument, the questionnaire passed through semantic validation, carried out by six experts and a pilot study, resulting in changes, insertions and exclusions of some items. After these changes, the questionnaire was applied to a sample of 283 Brazilian students and another one of 335 Portuguese students for further statistical validation. The reliability of the instrument was evaluated by the Cronbach Alpha test, which reached an internal consistency of 0.856 for the Brazilian sample and 0.830 for the Portuguese one. The Kaiser-Meyer-Olkin (KMO) and Bartlett's Sphericity tests confirmed the feasibility of factorial analysis. Thus, the questionnaire developed and applied in Brazilian and Portuguese university courses was duly validated and is in conditions to be used for the evaluation of students’ scientific literacy on genetic engineering, being an important contribution to future research.
