“…For example, a recent online survey on Human Papilloma Virus vaccination uptake in a university in Michigan has attained a response rate of 19% (192/1000) (Navalpakam, Dany, & Hajj Hussein, 2016). A study on preventive behaviors against pandemic influenza in 2009 in a university in Washington DC had a response rate of 17% (819/4900) (Katz, May, Sanza, Johnston, & Petinaux, 2012). However, some health-related surveys in university settings with high response rates generally considers a special population with certain restrictions, such as medical students (Afonso et al, 2017;Giri, Bangal, & Phalke, 2013), or the administration of the questionnaire was carried out during an event in which a large group of students were gathered (Kongnyuy et al, 2007), or they were recruited around a student healthcare center (Okafor, Hu, & Cook, 2015).…”
