Usefulness of health triangulation

Abstract

The beginnings of triangulation as a methodological strategy in research ocurred in the second half of the 20th century, specifically, in qualitative research when it was used as a strategy to corroborate the findings from two different sources of information. Subsequently, it began to be used as a strategy to achieve completeness of the phenomenon under study. The usefulness of triangulation is that it provides greater flexibility in the interpretation of the data because with the use of different sources a more complete picture of the problem is obtained. Triangulation can occur at various levels, not only in the methods and can use a wide range of techniques. The triangulation process is an arduous task because it tries to mediate the differences between two or more sources of information, methodological approaches, designs, theoretical perspectives, researchers and data analysis to compensate the weaknesses of a single strategy to achieve integrity or confirmation of the findings
