Theory usage in empirical research in ISIC conference papers (1996-2020)

Introduction. Measuring the use of theory that informs empirical research demonstrates the rigour of research in a discipline. It also identifies key theories and connections to other disciplines. This study focuses on use of theory, broadly defined, in information behaviour.Method. Full-length empirical papers from ISIC conference proceedings were analysed. Kumasi et al.'s (2013) theory talk framework was adapted for determining the level of theory use.Analysis. Content analysis was used to identify theories, level of theory use, and discipline of origin for theories in the papers.Results. Most ISIC empirical papers include theory and more than half of them use theory substantially. Most theories are drawn from information science and other social sciences. Kuhlthau's information search process is the most frequently mentioned framework.Conclusions. ISIC empirical papers continue to set a high standard for quality, demonstrating consistent theoretical rigour throughout the years studied. Their authors draw mainly on key information behaviour theories and models, as well as some lesser known and non-information science theories..
