This article sought to collect basic and relevant information about methodological triangulation make a first approach the principles underlying its use, potentiality scope, advances limitations, some alternative proposals surpass them. In that sense, it is an attempt operationalize concepts present procedures conduct rigorously. place, conceptual aspects types of are presented, in second princ...

PURPOSE To show how triangulation with qualitative and quantitative methods can help confirm a theory to a greater degree than can either method alone. CONSTRUCT: Coherence view of theory structure and confirmation. Evidence helps confirm a theory if the theory is the most coherent way of accounting for the evidence, and one theory is more coherent than another insofar as it leaves fewer unansw...

PURPOSE To explore various types of triangulation strategies and to indicate when different types of triangulation should be used in research. METHODS Reviews included literature on triangulation and multimethod strategies published since 1960 and research books specifically focusing on triangulation. FINDINGS Triangulation is the combination of at least two or more theoretical perspectives...

Introduction: Requirements Engineering process is a crucial phase in software development. In order to achieve a successful design of health information systems (HISs), applying the best methodologies is essential. Therefore, the aim of the present study was to design pediatrics Epilepsy Information System (EPIS) as well as the use of triangulation approach in elicitation and validation of epil...
