In this article, we present a qualitative discussion of 28 empirical studies on self-managing team-work and psychological well-being. We address three questions: (a) Which variables did they include and which results did they obtain?; (b) How did authors deal with issues of level of theory, measurement, and analysis?; and (c) Do such level issues affect the results of the studies? This review demonstrates that only job satisfaction is consistently related to self-managing teamwork. In addition, authors often fail to specify the level of their theory, thereby impeding judgment on the appropriateness of analysis procedures. Finally, we present preliminary evidence that level issues may affect the results. We plead for the incorporation of multilevel theory andanalysistechniquesintothefieldofself-managingteamworkandpsychologicalwell-being.
