Addressing Theoretical Concerns Regarding the EPPM. Edition No. 1
VDM Publishing House, April 2009, Pages: 68
The Extended Parallel Process Model (EPPM) is a
theory developed by communication scientists studying
fear appeals. The EPPM is widely utilized by health
communication, health psychology, and public health
scholars. It is a powerful model that is capable of
providing insight on why individuals are likely to
accept or reject fear appeal messages. However,
previous research has identified several theoretical
concerns about the predictive power of the EPPM.
Adopting the concerns expressed in previous studies
as a theoretical framework, two separate studies were
conducted to assess the validity of incorporating
perceived barrier and response costs constructs to
the EPPM. Regression analyses from both studies
suggest that the predictive power of the EPPM will
not be improved by incorporating these additional
variables.
