Adding consequence reflective constructs (e.g., Y and Z) to the focal formative construct (e.g., X) to attain model identification makes the estimate of parameters associated with the focal construct (X) a function of the selection of the external constructs (Y and Z) (Diamantopoulos, 2006), and hence causes potential interpretational confounding (Howell et al., 2007)."
