Objective: The aim of this article is to present the new instrument for evaluating congress abstracts of SCCh, in use from 2014, so as to standardize its application item by item. Material and method: Two-stage study with qualitative methodology for generating items and construction of the measuring instrument. In the first stage a collection of items was based on a review of the literature. In the second, the instrument was built by applying reduction items through a panel of experts. Thus, content validity was determined. The expert panel consisted of 6 members. Three clinical epidemiologists and three members of the SCCh. All with Master’s degree or PhD and research experience. Qualitative strategy is applied by Delphi technique; after the draft was presented to a panel of experts other than the above, at a meeting of ad-hoc working group, organized by the SCCh; at which time the proposal was discussed, the wording of items and domains was refined based on examples and the final instrument defined. Results: The items generated in the first stage (n = 15), who finished with the second draft; were grouped into 5 domains: introduction, material and method, results, conclusion, importance, originality and interest of the study; and overall presentation. When applying the questionnaire to the second panel of experts, a reduction items was generated and an item is added. Thus, the final instrument was composed of 10 items, grouped into 6 domains was constructed. Conclusion: A detailed description of the scale and guidelines for its implementation is presented, which will confer adequate reliability of the measurements.
