香港中文大學何鴻燊防治傳染病研究中心現進行一項研究，試行應用擴增實境技術協助進行愛滋病毒抗體自助測試。

本研究的對象是年滿十八歲、懂得使用智能電話的男男性接觸者。若您同意參與是項研究，您將要於網上系統登記並完成一份不記名的網上問卷，內容包括您的社交網絡和愛滋病測試服務的使用及有關行為習慣。登記網上系統需要一個有效的電郵地址。完成問卷需時約 10–20分鐘。完成問卷後，您可以索取一個愛滋病毒抗體自助測試套裝。然後，電腦系統將會將您隨機分配至擴增實境組別或對照組別。所有參加者均會獲發一個附說明書的自助測試套裝。擴增實境組別的參加者將獲邀在進行自助測試時，使用智能手機登入本網頁擴增實境頁面按照畫面指示進行自助測試，過程中將會收集使用數據及元數據。不論您獲分配至哪一組別，您需要在測試後將有關結果上載到系統，以及填寫一份有關自助測試可用性的問卷。寄送測試套裝需要收集您的聯絡電話及可供送遞的地址供聯絡用，研究完成後將會銷毀；您不需為此支付運費。完成所有程序後您將可獲價值港幣$20的現金券。您可以選擇留下聯絡方式，我們會在二零二三年三月三十一日前聯絡您有關領取有關金額以答謝您的參與。

這是一項不記名的研究，研究結果會以統計數據形式發表，個別資料將會保密。如果測試呈陽性，參與者將獲轉介至公營醫療服務作醫學跟進。請注意問卷內容涉及敏感和有關性行為的問題。另外，收集的數據會用作數學模型的參數。參與本次研究沒有可預見的心理，生理，社會，法律，或者經濟危險或得益，但採樣過程可能有輕微的痛楚或不適，及有可能因陽性測試結果感到憂慮。

我們誠意邀請您參加這項研究，參加與否純屬您的個人意願。您可於任何時間退出本項研究。即使您不同意參與，或於其間退出，將不會影響您現時於診所或醫院的診治程序。研究過程中，只有參與此項目研究的工作人員才可以閱覽相關記錄。研究結果會以統計數據形式發表，個別人士資料將會保密；而研究數據將會保留不多於五年。假如您中途退出，有關問卷將會被銷毀，不會被記錄和分析。如果您有更多關於本研究項目的問題，請與香港中文大學關子浩博士聯繫 (電郵 thkwan[at]cuhk.edu.hk 或 於辦公時間內致電 2252 8862)。香港中文大學 – 新界東醫院聯網臨床研究倫理 聯席委員會被授權在有需要時審視個人資料藉以評估研究倫理。如果你有更多關於臨床研究倫理相關問題，請與該委員會聯繫 (電郵 crec[at]cuhk.edu.hk 或 致電 3505 3935) 。

Stanley Ho Centre for Emerging Infectious Diseases of The Chinese University of Hong Kong is now conducting a study on applying augmented reality (AR) technology for assisting the performance of HIV self-tests.

Study subjects are men who have sex with men aged 18 years or above who are smartphone users. Should you consent to participate in this study, you will be asked to complete an anonymous self-administered online questionnaire which takes about 10-20 minutes through an online system, registration to which requires a valid email address. Your social network, utilisation of HIV testing services and related behaviours would be enquired. Upon completion of the questionnaire, you could request for an HIV antibody self-test kit. The computerised system would then randomly allocate you into either AR or control group. Whichever group you are allocated, you would receive a self-test kit with a written guide and be asked to upload the test result after completion and to fill out a survey regarding usability of the self-test. Participants in the AR group would be invited to use the smartphone to access the Augmented Reality page in this system and follow the instructions therein to perform the self-test. For delivery and contact purposes, you will be asked to provide a contact number and a postal address. These will be destroyed upon study completion. You would not be asked to pay for the delivery. An incentive of HK$20 would be given after completion of all procedures. You could leave your contact information so that we could contact you for delivering the incentives by 31 March 2023.

This is an anonymous study. Study results will be statistically presented without disclosure of personal level information. If you are tested positive, referral would be made to specialists in the public service. Participation is entirely voluntary and will not lead to any foreseeable psychological, physiological, social, legal or commercial risks or benefits, apart from the minimal pain and/or discomfort associated with self-sampling and testing, as well as the anxiety experienced by participants who may happen to have tested positive. Please be advised however that sensitive questions relating to sexual behaviour are included in the questionnaire and data collected would be used for parametrisation in mathematical modelling.

We sincerely invite you to join the study, the participation of which is however entirely voluntary. You can quit this study whenever you wish. Your access to clinical services would not be affected if you refuse to join the study, or request to withdraw after joining. All research data would only be accessible to researchers and their staff. Results of the study would only be used for global analysis without referral to individual patient. Individual’s information would be treated in strictest confidence. Research data would be stored for no more than five years. In the event that you withdraw from the study, questionnaire data would be destroyed, and that these would not be recorded or included in the subsequent analyses. Should you have any further enquiry about this study, please contact Dr Tsz Ho Kwan at 2252 8862 or thkwan@cuhk.edu.hk. The Joint Chinese University of Hong Kong – New Territories East Cluster (CUHK-NTEC) Clinical Research Ethics Committee is authorized to access the subjects' records related to the study for ethics review purpose. For enquiry regarding Clinical Research Ethics, please contact Joint CUHK-NTEC Clinical Research Ethics Committee at crec@cuhk.edu.hk and phone at 3505 3935.
