Extended parallel process model and H5N1 influenza virus.

This study integrated the Extended Parallel Process Model and forewarning cues to assess the promotion of preventive measures against the H5N1 influenza virus, a significant health threat that affects Asia, Europe, and the USA. There are two types of forewarning, (1) telling the audience that they will hear messages intended to persuade them and (2) telling the audience the topic and stance of the impending persuasive message. Analysis of ratings by 265 undergraduates indicated that forewarnings of the topic and stance of a promotional message on the H5N1 virus facilitated elaboration of coping-related thoughts which enhance perceived self-efficacy and a stronger behavioral intention to combat H5N1. Conversely, the elaboration of danger-related thoughts evoked some fear but enhanced source perception.
