Cultural-Psychological Differences, Social Acceptance of Same-Sex Relationships, and Dating App Use Motives of Young GBMSM: A Comparative Study Across Hong Kong, Taipei, and Osaka.

Gay-specific mobile dating apps such as Grindr are popular among young gay, bisexual, and other men who have sex with men (GBMSM) worldwide. However, how the use of these apps differs between regions is underexplored. In this study, we drew on the uses and gratifications literature and cross-cultural studies to examine how cultural-psychological differences (sensation seeking and communication apprehension) and social acceptance of same-sex relationships are associated with the motives for using gay dating apps in three East Asian cities.
