If you are quick enough, I will think about it: Information speed and trust in public health organizations

Highlights：

• Little is known about how people process source credibility in social media health messages.

• We conducted an experiment manipulating message speed and measuring trust.

• Results suggest an indirect relationship where update sped drives elaboration, which in turn predicts perceptions of credibility.

• A recently developed measurement model for trust in public health organizations is endorsed for its parsimony and convergent validity.
