從使用者觀點，檢視虛擬實境技術在衡鑑能力評量的可行性

The Feasibility of Virtual Reality in Measuring Psychological Assessment: Student and Psychologist Views

"本研究將虛擬實境（virtual reality, VR）技術用於「VR版心理衡鑑初次晤談客觀結構式臨床測驗」（簡稱「VR版初次晤談OSCE」）的開發，並透過使用者觀點檢視VR技術在衡鑑能力評量的可行性。本研究包含測試階段與正式研究。在測試階段，本研究聘任六位諮商／臨床心理碩士生與心理師擔任模擬考生，檢驗「初次晤談OSCE」在諮商與臨床心理的通用性。模擬考生在「初次晤談OSCE」的測驗分數顯示，兩組模擬考生在「病史詢問」和「溝通技巧與專業態度」面向，皆未呈現顯著差異，初步證實其在諮商與臨床心理的通用性。正式研究階段，本研究招募37位研究參與者，分成臨床組學生、諮商組學生與諮商心理師三組，檢驗VR技術在衡鑑能力評量的可行性與VR系統的設計品質。三組參與者在「心理衡鑑能力評量表──簡明版」測量結果顯示，「VR版初次晤談OSCE」用於「鑑別診斷」與「統合推論」的可行性優於「溝通技巧」與「專業態度」。在「虛擬實境使用性量表」測量結果顯示，參與者在VR系統設計方面，對於「使用者介面」與「求助功能」評價最高，認為「語音辨識」與「互動性」設計仍有待改善。從使用者觀點而言，VR技術在衡鑑能力評量的應用具有可行性，待系統開發成熟後，可進一步評估其在OSCE施測成本節約的效果。"

"Psychological assessment has been regarded an essential competency domain in professional psychology. Influenced by the competency-based movement, researchers and educators start to redesign new measurement tools for assessing psychological assessment competencies (PACs) of psychologists from entry to practice. Compared with physicians and nurses, license examinations of professional psychologists still heavily rely on the paper-pencil tests to measure professional competencies of psychologists. In the past five decades, an objective structured clinical examination (OSCE) has become one of the most commonly used measurement tools to assess professional knowledge, clinical skills and professional attitudes of healthcare professionals at the same time. Several meta-analysis studies have confirmed that an OSCE is not only a reliable and valid measurement tool for assessing clinical competencies of healthcare professionals, but also a good teaching aid to facilitate a wide range of clinical skill training courses.

Lan et al. (2011) proposed four possible factorsaffecting the OSCE application in professional psychology. First of all, competencies in professional psychology (e.g., rapportbuilding skills, expressions of empathy) are more abstract and difficult to measure than those in medicine and nursing. Second,it requires longer time and more effort to develop and administer a psychology OSCE than a medical OSCE or a nursingOSCE. Third, faculty members and practicing psychologists need to receive further training (e.g., taking an OSCE rater trainingworkshop) to ensure that they reach inter-rater agreement before scoring student or participant performance on a psychologyOSCE. Last but not least, the major obstacle to adopting OSCEs in professional psychology is high cost of running an OSCEon a regular basis. Compared with the resource input of a medical OSCE, the resource input of a psychology OSCE is relativelyinsufficient. If the cost of running a psychology OSCE could be effectively reduced, it would help to promote the OSCEapplication in professional psychology."
