Overview
WeChat-based
Qualitative interviews were conducted with 8 participants: 5 alters (A1-A5) and 3 alter-egos (B1-B3). The major barriers to transformation from online alters to offline egos (ie, the reasons why online alters did not undergo HIV testing at Lingnan and thus did not transform into alter-egos) were (1) low awareness of the functions of the WeChat-based mini-program “ChaBei” for booking HIV testing services, (2) limited access to HIV e-reports at offline testing facilities, and (3) no demand for offline HIV testing.
