As a public health concern, elder abuse has been widely studied in various countries and regions (e.g. Roberto, 2016;Sooryanarayana et al., 2013;Williams et al., 2017;Yon et al., 2017). In the United States, the prevalence of elder abuse was found to range from 10% to 47%, depending on ethnicity, gender and type of abuse (Dong, 2015). In another study in Hong Kong, approximately 27.5% of older adults reported being abused in the preceding year, and 88.2% of the perpetrators of elder abuse were their adult children (Yan & Tang, 2004). Similar results were found in Taiwan, where it has been reported that 76% of elder abusers are adult children (Chong & Jiang, 2000). It is also estimated that 36.2% of older adults in rural areas of China experienced at least one type of abuse in the preceding year (Wu et al., 2012). Furthermore, one large-scale survey on families in six regions in China found that the lifetime prevalence of children witnessing elder abuse ranged from 8.3% to 14.3%, whereas the preceding year, this prevalence had ranged from 3.7% to 9.4% (Chan, 2014).Living arrangements, or more specifically whether elders live with their adult children, have been identified as a significant risk factor for elder abuse (Wu et al., 2012).
