Untangling Threat during Inoculation-Conferred Resistance to Influence

Threat plays a pivotal role in many theoretical explanations for how inoculation confers resistance, but some empirical data raise questions about threat's role in inoculation. Our study explores some of the unresolved dimensions of threat in inoculation theory. Results indicate that an explicit forewarning included in an inoculation treatment message generates threat, as does the presence of counterarguments and their refutations. Follow-up tests suggest that the forewarning component may be most responsible for generated threat in inoculation, and that a prompt to consider experienced threat may lead to enhanced resistance to subsequent attack messages.
