“…Some researchers have claimed that their studies support a four-factor MSCEIT structure that is consistent with the four-branch model (e.g., Brackett, Rivers, & Salovey, 2011;Day & Carroll, 2004;Mayer et al, 2002Mayer et al, , 2003. Whereas others have doubts concerning the suitability of this factor structure, in most cases, these researchers have used a college student population (Fan, Jackson, Yang, Tang, & Zhang, 2010;Gardner & Qualter, 2011;Gignac, 2005;Palmer et al, 2005;Roberts et al, 2006;Rode et al, 2008;Rossen, Kranzler, & Algina, 2008) and proposed alternative one-, two-, three-, or four-factor models. Despite the proliferation of models, the hierarchical model (i.e., the MSCEIT's implied theoretical structure of eight tasks, four branches, two areas, and general EI) has been tested on a few occasions and yet is almost never proposed as the best model for later analyses, even though Mayer et al (2002) thought that this type of test best determined the clustering of MSCEIT scores according to theory.…”
