Scientific contributions of within-person research in management: making the juice worth the squeeze

A multitude of studies in the management literature are focusing on within-person phenomena. The study of such phenomena offers great promise as within-person research facilitates the capacity to enhance temporal precision, show change over time, and reveal the kinds of novel insights that are not possible if relying solely on a traditional between-person perspective. Drawing on the features of within-person research that comprise its unique value proposition, we conduct a quantitative and narrative review of within-person studies to ascertain the degree to which these studies are maximizing the contribution and impact that they can make to the field of management. We pose three research questions that we present as a holistic framework for assessing the contributions of within-person research. To answer our questions, we synthesize across studies and analyze variability data, correlational data, and researchers’ hypothesizing to show (a) the degree to which hypotheses in within-person studies incorporate temporality; (b) the differential within-person fluctuation and variability that exists based on construct, theoretical, and measurement-related factors; and (c) the degree to which within-person relationships are different from equivalent between-person relationships. While our data and conclusions offer insight into the contributions being made by the within-person literature at large, we also propose that our framework can be used at the individual study level of analysis to help optimize the contributions made in future within-person research.
