Investment Models Scale (IMS)

The Investment Models Scale (IMS) consists of two sets of items associated with the four central constructs of the Investment Model (IM): facet items and global items. Facet items measure the antecedents of commitment - satisfaction, quality of alternatives and investment size. These facet items are included in the IMS to activate in memory and illustrate each of the respective constructs, in order to facilitate its correct apprehension and the response to the global items. The set of global items measure satisfaction, quality of alternatives and investment size, as well as the commitment level toward the relationship.
