Establishing model parsimony is an important component of structural equation modeling (SEM). Unfortunately, little attention has been given to developing systematic procedures to accomplish this goal. To this end, the current study introduces an innovative application of the jackknife approach first presented in Rensvold and Cheung (1999). Unlike the traditional application of jackknife procedures for the purpose of identifying outliers and influential cases within a dataset, this jackknife procedure is applied for the purpose of identifying and eliminating items from a structural model. Items are identified through the jackknife procedure and eliminated from the model without altering the measurement or structural integrity of the model. The goal of this application is to create the most parsimonious model by reducing the number of items in an inventory, without altering the construct represented by the model.
