11. To summarise
1. The evaluation of digital information sources varies across
users, hence there is no “one-solution-to-fit-all”
2. People’s trust judgements of online health information
become more content-oriented as they progress in age (as
opposed to being more user-friendly).
4. The main factors to influence trust judgements across
different groups are Content (Credibility), Recommendation,
Ease of Use and Brand.
3. Women seem to attribute more importance to specific
factors influencing trust formation than men.
