Why does construct definition matter in information systems research? This paper investigates the potential dangers of misapplying theoretical constructs and their measurement scales in information systems research, emphasizing the importance of precise definitions and context-specific applications. The study uses the example of user satisfaction with a decision support system to demonstrate these risks. Through a controlled field study, the research highlights the confounding effects that arise when general instruments are used in situations where more narrowly focused, context-specific instruments would be more appropriate. This can lead to inaccurate or misleading results, undermining the validity of research findings. By emphasizing the careful application and operationalization of constructs, this paper provides valuable guidance for researchers and practitioners in the information systems field. It underscores the need for thoughtful consideration of construct overlap and the selection of appropriate measurement tools to ensure the integrity and relevance of research outcomes.
