Abstract
Research into self-injury has been advanced by large-scale surveys mainly overseas. Although several fact-finding surveys are found in Japan, these have issues such as limited sample size and types of self-injury. The current study aims to organize the knowledge about the actual state of self-injury in Japan through systematic review. Nineteen surveys were extracted from twenty-two articles found in databases. Regarding the type of self-injury in Japan, similar types to those in other countries were extracted, such as cutting, hitting, scratching, sticking, pinching, and burning. The life-time experience rate of self-injury was highest at 24.4% for self-hitting. And that of self-cutting was only 6.8%. Meta-analysis showed no difference by sex in the appearance rate of self-injury as a whole, but there were significant sex differences between self-cutting (female > male) and self-hitting (male > female). Based on the current study results, the issues and prospects of future self-injury support are discussed.
