It discusses the concept of triangulation, as developed in the social sciences by Campbell and Fiske (1959), with an emphasis on the process of combining and integrating multiple methods. It reviews previous applications oftriangulation in translationand interpretingstudies and describes the advantages of systematic triangulation for empirical research. The implications of this approach for future research in public service interpreting concerningthe trustworthiness of the interpretative nature of qualitative inquiry are also discussed. To demonstrate the practical application of triangulation in public service interpreting settings, this paper draws on a case study conducted by the author where triangulation of participantobservation, focus groups and audio-recordedinteractionwas employed. The integration of the different research methods utilized, as well as the findings derived by triangulation, are illustrated through examples from this study. %K Public service interpreting %K Triangulation %K Trustworthiness %K Qualitative methods %K Interpretación en servicios públicos %K Triangulación %K Confiabilidad %K Métodos cualitativos %K Filología %K Philology %~ Biblioteca Universidad de Alcala
