個案工作者在執行家庭風險調查必須儘可能達至精確，以提昇預防效力。據內政部（2009）「推動高風險家庭關懷處遇計劃」中針對基層的通報單位，所訂立的「高風險家庭評估表」作為篩選轉介的參照標準，除何謂「高風險家庭」無明確定義；其功能實屬通報指標；另其中的開案、處遇及結案建議，因過於概括性而未能有具體及標準的量化指引供裁定，致今天的個案工作者在缺乏「風險評估模式」，以評定家庭是否處於風險中，而可能面臨最困難的決定，如何謂「高風險家庭」、高風險家庭開案、結案及服務決定的標準是如何的窘境。故，除非在「高風險家庭預防服務」中提供明確的高風險家庭的定義、風險評估指標及評量的基礎訓練，才是解決「高風險家庭」之個案工作者工作困境的可能。鑑此，本文探討的重點，為「風險評估」納入高風險家庭預防服務的意義與重要理由，並以「韌力」的觀點，應用於解析高風險家庭中，評量可能的風險、保護因子與程度，作為執行家庭風險調查的立基，以增益預防的力量，另提出相關議題的討論與建議。

Case workers must conduct a precise risk assessment of family risk to enhance the prevention effects. According to the Ministry of Interior (2009) "intervention projects should emphasize the care of high-risk families." A standard method of assessment is required to assess families as being high risk to refer them for services. However, there is no official definition for what is considered a "high-risk family," which is necessary to develop the standard assessment. Additionally, because the intervention suggestions are too general or inadequate, standard guidelines cannot be developed. Therefore, a complete risk assessment model to assess whether a family is at risk is lacking. As a result, today's case workers lack a risk assessment model and face difficult decisions of deciding whether a family is at risk; for example, whether to open and terminate services to families no longer considered high-risk.To solve this issue, case workers must be given basic training on how to evaluate, and an evaluation index of risk and the explicit definition of a high-risk family must be developed and implemented in services for high-risk families.The purpose of this article is to evaluate the functions and reasons for high-risk family services, analyze the effectiveness of high-risk family services, and assess the possibility and extent of risk with the view of resilence to provide an importance reference for projects. Finally, this study concludes that to prevent risk, a risk assessment for high-risk family services must be developed and implemented.
