Second, the manuscript should be carefully edited as there are a fair number of grammatical and typographical errors, including lack of subject-verb agreement in places (e.g., using “were” and “was” in the same sentence, both referring to the same measure - CU traits), omitted words, and so forth.
First, it is recommended that the authors provide more information about the selection of the cluster solution. That is, no information is available in the present manuscript about alternative cluster solutions from the analysis, for example, the extent to which BIC and the silhouette coefficient differed for other solutions and so forth. It would help the reader to have some information available as a way of arguing more strongly that the accepted solution (which does make theoretical and empirical sense) is the strongest grouping.
