family and psychological profiles
Version: 0Date: 18 Jul 2017
Reviewer: Michele Shedlin
Reviewer's report:This is an interesting secondary analysis of selected Spanish data from the 2014 HBSC data base.
It adds to the literature regarding EC use among adolescents. Especially interesting was theprevalence of use and the information on family context among girls with multiple use. Issueswhich should be addressed before publication are some editing and more discussion regardinglimitations imposed by the sample. The question of biases is especially important when such alarge percentage of the total sample was described as non response or considered lost. While thisdoes not negate the conclusions of the paper, how this limitation might affect conclusions iscalled for. Finally, the information provided on the study scales might be better in an appendix ortable and simply listed in the text.
