In Korea, an amendment to the Child Welfare Act was made in 2008 that required a national study estimating the occurrence rate of child abuse and neglect every 5 years. The present study reports the major findings of the first national study conducted after the 2008 amendment. The aim of the study is to estimate the prevalence of child physical and psychological maltreatment (CPPM) in Korea and to explore the basic characteristics associated with such incidents. Household surveys were administered to caregivers and focal children who were school age and older. We estimated the prevalence of CPPM using the Parent-child Conflict Tactic Scale, which was developed by Straus et al. (1998). The occurrence rate of CPPM was 25.3 % in Korea, with instances differing by household income, poverty status, and size of the region. Children who experienced physical and psychological maltreatment were more likely to witness the abuse of their siblings and domestic violence. The implications of the findings are discussed and recommendations made for further research.
