One for all, all for one: Social considerations in user acceptance of contact tracing apps using longitudinal evidence from Germany and Switzerland

作者：

Highlights：

• We model CTA acceptance by integrating social considerations into privacy calculus.

• A longitudinal study with 589 participants from Germany and Switzerland.

• Social risks (fear of mass surveillance) have a stronger impact than privacy risks.

• Social risks fully mediate the “privacy risks-CTA use” link.

• A substantial intention-behavior gap is revealed, with a nearly 40% dropout rate.
