10. Summary of the thesis results:

This study investigates the current state of personality traits, motivations for using dating apps, and the relationship between personality traits, motivations for using dating apps, and demographics among young Vietnamese adults. The results show that agreeableness is the most prominent trait, while extroversion is the lowest; female and heterosexual groups have higher levels of psychological disturbance; high-income individuals tend to be more agreeable and conscientious; and bisexual individuals exhibit the highest level of openness. Regarding motivations, "Social interaction/social engagement" is the strongest, while "Increasing sexual experiences" is the weakest. Women prioritize social interaction and entertainment, while men lean towards relationship-seeking and sexual motivation; working professionals focus on relationship-seeking; those with postgraduate education have higher sexual motivation; and bisexual individuals have the highest entertainment motivation. Psychological disturbance, extroversion, and conscientiousness influence the motivation for social interaction; openness influences the motivation for entertainment.

11. Practical applications:

The thesis highlights the importance of developing a warning system for dating app users showing signs of psychological distress, helping them identify problems and seek timely support. Simultaneously, it contributes to the development of educational programs aimed at helping young people understand themselves, set goals for using the app, and build healthy relationships.

12. Future research directions: further research into groups with diverse gender identities or groups with vulnerable personality traits.

Findings indicate that agreeableness is the most prominent trait, while extraversion is the least expressed. Female and non-conforming individuals exhibit higher levels of neuroticism. Those with higher income tend to show greater agreeableness and conscientiousness. Bisexual individuals display the highest levels of openness. Regarding motives, “Social Inclusion/Socializing” is the strongest, while “Enhancing Sexual Experience” is the weakest. Females prioritize social and entertainment - related motives, whereas males are more inclined toward relationship-seeking and sexual motives. Employed individuals emphasize relationship-seeking, while those with postgraduate education exhibit stronger sexual motives. Bisexual participants report the highest level of entertainment motive. Neuroticism, extraversion, and conscientiousness are associated with socializing motive, while openness is linked to entertainment motive.
