Measuring qualities needed for interdisciplinary work: The Intellectual Virtues for Interdisciplinary Research Scale...

Previous work has suggested that the problems hindering the success of interdisciplinarity could be overcome by fostering certain intellectual character strengths in scholars. However, how to assess and cultivate the specific virtues required for interdisciplinarity among researchers is still a matter of inquiry. The general objective of this paper was to develop a psychometric instrument to assess intellectual virtues that are essential for interdisciplinary inquiry among researchers. To achieve this goal, two studies were conducted. Study 1 developed a new scale and studied its correlation with other validated measures. Study 2 focused on conducting a confirmatory analysis of the structure obtained in Study 1 and investigated the relationships between the new scale and the researchers' levels of (i) experience and productivity in interdisciplinary collaboration and (ii) satisfaction regarding the results of their interdisciplinary inquiry. The EFA conducted for Study 1 identified four dimensions: (1) intellectual empathy, (2) open-mindedness and intellectual humility, (3) intellectual perseverance, and (4) curiosity. Indeed, the pools of items that were initially developed to measure intellectual humility and open-mindedness in a separate way converged into a unique factor or dimension. The confirmatory factor analysis conducted for Study 2 corroborated the four-dimensional structure observed in Study 1 via a new different sample. In addition, Studies 1 and 2 also analyzed convergent validity through the AVE and correlated the IVIRS with other scales that measure intellectual virtues (open-mindedness, curiosity, intellectual humility, and perseverance) in a general epistemic context. The second study demonstrated that researchers with significant experience, productivity, and satisfaction in the context of interdisciplinary investigation also presented elevated levels of the intellectual virtues that we identified as essential for such research. Our analysis demonstrates that the IVIRS is a valid measure of the intellectual virtues needed for interdisciplinarity and paves the way for the future design of interventions to cultivate these character traits in scholars.
