Purpose – Study the effects of cognitive style on interdisciplinary scientific collaborative group performance and group satisfaction. Methodology– We propose an approach of measuring group cognitive style to investigate the relationships between group cognitive style, demographic factors, group performance and predictors of group satisfaction. Group cognitive style will be measured by five psychometric instruments: the Cognitive Style Assessment (CSA), the Kirton Adaption-Innovation Index (KAI), the Herrmann Brain Dominance Instrument (HBDI) and the NEO-Five Factor Personality Inventory (NEO-FFI). Group performance will be measured through authors from different institutions, either as co-authors in a scientific publication or as colleagues within a research project. A ten-items questionnaire will be administered for the measure of group satisfaction. Value –This methodology puts in evidence that group cognitive diversity may have significant effects on the effectiveness of interdisciplinary scientific collaboration. Practical implications – The outcomes of the application could optimize the resource sharing and knowledge transfer within the interdisciplinary collaborative groups, and improve the effectiveness of interdisciplinary scientific collaboration. It can be extended in large scale with no limit in academia. Our study could help practitioners, managers and designers make right decision when they design their own collaborative work group.
