Here are a few options, depending on where you want the focus to be:
- Most formal: “Study Reveals Gen Z Underestimates the Impact of Social Media on Loneliness in Hong Kong”
- Concise and academic: “Hong Kong Survey Highlights Disconnect Between Gen Z Perceptions and Social Media-Induced Loneliness”
- Direct and professional: “New Data Indicates Gen Z Underestimates Social Media’s Contribution to Loneliness in Hong Kong”
My recommendation: The first option is the most balanced and suitable for a formal report or publication.
