“…From the descriptive results, the prevalence of NSSI among male students is 37.6% and that of female students is slightly higher (39.1%) than that of male students, which is not only higher than the survey results of Western countries (Burke et al, 2015; Ross & Heath, 2002; Whitlock, et al, 2007a, b), but higher than the survey results among Chinese middle school students (Wang & Wang, 2009; Xiao et al, 2008), but gender difference did not show too much significance. This finding is consistent with the conclusion of Yang, indicating that the hypothesis of “boy crisis” or “girl risk” of NSSI behavior of middle school students in China has not yet been confirmed (Yang & Xin, 2018).…”
