This study aims to investigate the factors on help-seeking behaviors among the disabled experiencing lifelong domestic violence and suggest practical plans to address the problems. According to an analysis of the data of the "2010 Domestic Violence Survey of South Korea", the occurrence rate of lifelong physical violence is 12.1% and that of severe physical violence is 6.2% among 273 adults with disabilities. The rate of help-seeking among the disabled experiencing lifelong domestic violence is 26.3%, which means two-thirds of the disabled experiencing domestic violence do so for a long time. The results of the study show that the experience of severe physical violence(p<.05), attitudes toward violence(p<.05), and awareness of domestic violence and related laws(p<.05) were found to have an impact on help-seeking behaviors among adults with disabilities experiencing domestic violence. However, an accepting attitude of disability and social connections of disabled were not found to have an impact on help-seeking behaviors. Based on these results, this study suggested raising awareness about domestic violence among the disabled, educating people with disabilities not to tolerate violence and informing them about the domestic violence-related legal system, and training service professionals (social workers, health professionals etc.) to screen the disabled for domestic violence and prevent them from becoming domestic violence victims.
