This study aims to provide practical and policy implications of intervention process of elder abuse by examining factors that affect older victim’s safety in the process of elder abuse intervention. We conducted in-depth interviews with eight counselors from the four Korea Elder Protection Agencies. A total of 10 elder abuse cases were analyzed based on the grounded theory method. These cases were categorized into two groups of cases: secured safety case and unsecured safety cases, and compared between two groups. The secured safety cases and the unsecured safety cases showed same causal condition, contextual condition, and interventional condition. However, the core phenomenon and the action-interaction strategy were different. Thus, in the intervention process of elder abuse cases, factors that influence the security of the older victim were older victim’s and abuser’s attitudes toward interventions and the response of related agencies. Based on these results, we proposed family education for the prevention of elder abuse, establishing strategies that increase the cooperation of older victims, designing interventions for abusers, and institutional implications for increasing the cooperation of related agencies
