ABSTRACT
Little research on elder abuse was conducted in Japan until the Society for Study of Elder Abuse began its research in 1993. In two studies (1993, 1997), which surveyed social workers and home helpers, neglect was found to be the most common type of abuse, and daughters-in-law more often associated with neglect than spouses, sons, or daughters because of long term poor relationships. The research identified three reasons for the long term poor relationships and the factors that precipitated neglect and/or psychological abuse by daughters-in-law.
