Resumen
This study explores some key aspects of the validation of instruments used in clinical data collection, which is part of a critical process for diagnosis and treatment in the medical field. Clinimetrics underscores the importance of validity, and reliability in the use of instruments for the accurate identification, and measurement of signs and symptoms. Validity ensures that the instrument effectively measures the variable of interest, while reliability indicates that repeated use of the same instrument will produce consistent results. The article addresses aspects related to instrument construction and validation, including theoretical and empirical foundations, validation by expert judges, pre-sampling tests, as well as construct and criterion evaluations. In addition, the application of exploratory and confirmatory factor analysis to validate the internal structure of the instruments is addressed. This work highlights the importance of accuracy in clinical practice and provides a detailed framework for ensuring the efficacy and relevance of instruments in different population contexts.
