DIAZ MORA, Evelyn; SAGARO DEL CAMPO, Nelsa María; ZAMORA MATAMOROS, Larisa e BARTUTIS BONNE, Milka Tanya. Appearance and rational validity of a methodology to study causality in health. Medicentro Electrónica [online]. 2023, vol.27, n.4 Epub 01-Jan-2024. ISSN 1029-3043.
Introduction:
the fundamental objective of medicine is to determine the causes that produce diseases. At the end of the 20th century, multivariate statistical techniques were used as reliable in the simultaneous analysis of different independent variables on an outcome.
Objective:
to determine the application of appearance and rational validity of a methodology to study causality in health.
Methods:
to evaluate whether the methodology corresponded to the research requirements, appearance validity was applied to assess the results obtained in its application, specifically, if the rules accurately reflect what happens in medical practice, through the use of rational validity.
Results:
the potential users of the methodology considered it acceptable in the measured aspects of the binary logistic regression. The highest percentage of the rules analyzed is in correspondence with what is stated in the literature; few raise aspects that do not necessarily occur in medical practice, but they do not contradict the literature either. The results of face validity were not favourable, since the methodology had not been used before in the context. A high percentage of correspondence regarding rational validity was verified between what was stated by the rules and the literature. It is important to note that finding something known reaffirms the validity of that rule.
Conclusions:
the rules obtained from the application of the methodology reflect, in general, what happens in medical practice.
