Plain English Summary
Background and study aims
Over the past two decades, significant changes have occurred in how men who have sex with men (MSM) find partners, moving from the traditional approach (in person at gay bars) to the Internet and now to smartphone dating applications (apps). Notably, both international and local studies have found a high prevalence of sexually transmitted infections (STIs) and risky sexual behaviours, such as condomless anal sex, substance misuse in conjunction with sex ('chemsex') and group sex, among MSM dating app users. Although the use of dating apps is an emerging sexual risk factor, little effort has been expended on the promotion of safe sex and good sexual health among the users of those apps. Previous studies in various populations have found that interactive web-based interventions can improve sexual health knowledge, attitudes and sexual behaviours. Therefore, the aim of the proposed study is to develop and evaluate the effectiveness of an interactive web-based intervention in improving the sexual health of MSM dating app users in Hong Kong.
Who can participate?
Adult men over 18 years who are homosexually active and use dating apps.
What does the study involve?
Chinese MSM dating app users who have had sex in the past 12 months will be recruited and randomly allocated into either the intervention (n = 200) or control group (n = 200). Subjects in the intervention group will receive the web-based intervention containing interactive content that (1) encourages a positive attitude towards consistent condom use and HIV/STI testing and negative attitude towards chemsex and group sex; (2) positions condom use and regular HIV/STI testing as normative; and (3) targets improved perceived self-efficacy concerning condom use and negotiation and HIV/STI testing. The control group will receive only web-based information without sexual health components. Subjects in both groups will be evaluated at baseline and three and six months after baseline.
What are the possible benefits and risks of participating?
One possible benefit is that participants can enhance their sexual health knowledge. There is no significant risk in the study.
Where is the study run from?
School of Nursing, University of Hong Kong.

Safe use of dating applications (apps) among men who have sex with men: developing and testing an interactive web-based intervention to reduce risky sexual behaviours
Acronym
Study hypothesis
Education regarding condom use and HIV/STI testing will result in (1) fewer risky sexual behaviours, (2) better efficacy in and positive attitudes towards condom use, and (3) more HIV and sexually transmitted infection (STI) testing.

Condition
Safe sex to prevent sexually transmitted infections (STI)
Intervention
Chinese MSM dating app users who have had sex in the past 12 months will be recruited and randomly allocated into either the intervention (n = 200) or control group (n = 200). Subjects in the intervention group will receive the web-based intervention containing interactive content that (1) encourages a positive attitude towards consistent condom use and HIV/STI testing and negative attitude towards chemsex and group sex; (2) positions condom use and regular HIV/STI testing as normative; and (3) targets improved perceived self-efficacy concerning condom use and negotiation and HIV/STI testing. The control group will receive only web-based information without sexual health components. Subjects in both groups will be evaluated at baseline and 3 and 6 months after baseline.
Participants will be randomly assigned to either the intervention group or control group via computer-generated block randomisation (with blocks of size 4) on a 1:1 randomisation ratio; no stratification will be applied.
