    Abstract

    Much discussion of research validity in information systems (IS) draws on the empiricist tradition, which presents an impoverished account of reality, making it difficult to formulate issues of validity that are pertinent to a practitioneroriented discipline. This is particularly true for external validity, which refers to the applicability, or relevance, of research to phenomena in the broader environment of practices, but also for construct and internal validity, which seek to establish rigour in human-centred practical research. Discussions of validity are often supplemented with implicitly realist notions that are not compatible with the espoused empiricism. We argue that critical realism presents a number of insights that profoundly clarify a discussion of validity in practitioner-oriented theory-testing research. We reformulate the notions of theory testing and research validity from the critical realist perspective and illustrate them using a description of a controlled experiment. Important new insights are gained into establishing each kind of validity.
