This study will evaluate the effectiveness of a program in promoting the safe usage of dating applications amongst young adults in Hong Kong. One group will receive the program regarding dating applications and the other group will receive a placebo program regarding health and exercise.
Dating applications are a popular platform to meet new people; however, they have been associated with risks such as unsafe sexual behavior and privacy concerns in young adults.
The study design is an open-labeled cluster randomized controlled trial with an intervention and a placebo control arm. The intervention group will receive a web-based intervention developed through focus group discussions, crowdsourcing contest, and a Peer-Vetted Creative Production (PVCP) workshop comprising of four short videos, a risk assessment tool, and a scenario game. The control group will receive a web-based resource with similar multimedia elements on health and exercise.
Based on the Information, Motivation, and Behavioral Skills (IMB) Model, the primary outcome of this study is self-efficacy in using dating applications measured by the General Self Efficacy Scale. Secondary outcomes include change in attitudes regarding risk perception measured by the Risk Propensity Scale and depression symptoms.
