This investigation explored three issues relevant to inoculation theory’s function. First, the stamina of inoculation-generated resistance was examined at 2-, 4-, and 6-week time intervals between treatment and persuasive attack. Second, inoculation and attack messages as booster treatments were compared. Finally, this study tested the ability of inoculation-generated resistance to withstand three persuasive attacks. Results from a 230-participant five-phase experiment indicate erosion of generated resistance with a longer time delay. However, booster treatments in the form of a second inoculation message demonstrate potential to lengthen the inoculation effect. In addition, generated resistance remained after three persuasive attacks.
