The purpose of this study was to produce risk assessment tool that enables care providers to evaluate symptoms of abuse when visiting a client's home for the first time. Also this study will help identify cases that need support to correct the causes of abuse and prevent future cases. A comprehensive list of risk factors affecting abuse was compiled using 106 recorded abuse cases in literatures. Risk factors that were seen repeatedly in these recorded cases were selected and combined to produce a risk assessment questionnaire for abuse of the elderly. Then a survey was performed on 100 care providers (effective replies 77) to confirm each items degree of contribution towards abuse. After that, a temporary tool was constructed to compare differences between abused case groups and non abused case groups. The results were used to assess a practical criterion for screening the cases. As a result, the risk assessment tool was constructed containing 55 items and 4 categories, such as 1) cared elderly, 2) care giver, 3) other family members and 4) care condition. Further studies are necessary to improve the precision of the screening criteria of the tool and to make the best use of it by care providers for promoting their assessment skills for more suitable activities on collaborative community health care.
