“…One possible reason for the large discrepancies in reported rates is the diverse and convenient participant samples, but another potentially more compelling reason is the differences in the inclusion and measurement of different forms of ACEs across studies. For example, across the eight studies, four omitted ACEs related to peer, community, and collective violence (Liu, Yang, Shi, Liu, & Wang, 2016;Wong, Fong, & Chan, 2015;Xiao, Dong, Yao, Li, & Ye, 2008;Xue, Lin, Sun, & Cao, 2017); two also excluded physical and emotional neglect (Ding, Lin, Zhou, Yan, & He, 2014;Wei, 2013), and one also excluded sexual abuse (Xue, Gao, & Cao, 2016). One study further reduced ACEs into four broad categories and reported on the overall prevalence of family, community, school, and personal adversity (Li et al, 2015).…”
