...emerge did we plan to follow up with a multidimensional latent class item response theory model (LC IRT) to more deeply test the dimensional structure of the scale (Bacci, Bartolucci, & Gnaldi, 2014; Bartolucci, 2007; Bartolucci, Bacci, & Gnaldi, 2014)....

...Only if this expected pattern did not emerge did we plan to follow up with a multidimensional latent class item response theory model (LC IRT) to more deeply test the dimensional structure of the scale (Bacci, Bartolucci, & Gnaldi, 2014; Bartolucci, 2007; Bartolucci, Bacci, & Gnaldi, 2014)....
