Fully Mediated Effects of Formative Measures Using MIMIC Constructs

James J. Jiang, Jacob C. Tsai, Gary Klein, Stacie Petter

Abstract


Formatively-measured constructs are increasingly applied in information system research mod-els. Recent work shows that exogenous formatively-measured constructs suffer from a number of problems that include interpretational confounding and a lack of external consistency.  Yet replacement by reflectively-measured constructs can lead to bias if not theoretically appropriate.  One solution may be to use a MIMIC construct composed of the formative measures as well as two additional reflective measures.  A simulation study indicates that a MIMIC so composed mit-igates the problems of interpretational confounding and poor external consistency allowing use broader use in a variety of structural models.
