This investigation dealt with the role and impact of affect in the process
of resistance. A total of 597 participants took part in tile study in 4 pha
se spanning 6 weeks. Initial results indicated that the cognitive, affectiv
e-anger, and affective-happiness inoculation treatments all conferred resis
tance to persuasive attacks. Structural equation analyses were conducted on
the cognitive, affective-anger, and affective-happiness experimental inocu
lation conditions in order to examine the process of resistance. The result
s across all 3 conditions revealed a direct path in which inoculation treat
ments directly induced resistance to persuasive attacks. However, indirect
paths to resistance varied across the 3 experimental conditions. Cognitive
inoculation treatments contributed to receiver threat and counterarguing ou
tput, which, in turn, enhanced resistance. Thus, tire cognitive inoculation
treatments triggered a process that is consistent with McGuire's theoretic
al explanation for resistance. By contrast, both affective-anger and affect
ive-happiness inoculation treatments relied more heavily on elicited emotio
nal responses. Finally, the results indicated that greater receiver involve
ment was positively associated with experienced anger and, therefore, indir
ectly contributed to resistance, whereas greater receiver self-efficacy ten
ded to dampen resistance.
