Most researches study elder abuse as an integration, lacking separately studying elder financial abuse. This leads to the difficulties for practitioners of detecting and identifying core risk factors for elder financial abuse. For these 5 articles, Bagshaw et al. (2013) researches are directly focusing on studying elder financial abuse, core risk factors and related issues, which are of sufficient quality and are highly relevant to my area of concern. However, there are still some limitations of methodology applied. Davies et al. (2008) and Davies et al. (2013) used qualitative methodology, whereas Bagshaw et al. (2013) used quantitative methodology. Only Gilhooly et al. (2013) combined quantitative and qualitative methodology. As Hewitt-Taylor
