Stories are often used in health communication because of accumulating evidence of their potential to affect people’s attitudes and health behavioral intentions. Similarity between the reader and the story’s protagonist appears to positively influence narrative persuasion, but the exact role of similarity on persuasive outcomes is debated, as some research finds clear effects of similarity manipulations whereas others do not. Possibly, these mixed results were found because the similarity manipulations were not always relevant to the topic of the story. We conducted an experiment (N = 582) in which we varied the age and gender of the protagonist, features that were of central relevance to the story’s topic, namely breast cancer versus testicular cancer. There were two groups of participants: 324 students (mean age: 21.46 years) and 258 older adults (mean age: 56.83 years). Age similarity (but not gender similarity) had an effect on identification with the protagonist, transportation (i.e. the experience of being absorbed into a story), and the intention to donate, but only for students. For older adults, age or gender of the protagonist did not seem to matter, as nearly no differences in persuasive measures were found. As far as the underlying mechanism is concerned, the results of structural equation modeling showed that the concept of ‘perceived similarity’ would be a relevant addition to models of narrative persuasion, as it was significantly related to the narrative processes of transportation and identification, which, in turn, predicted attitudes and behavioral intentions, both directly—in the case of transportation—or indirectly, via the emotion of compassion. We conclude that both manipulated and perceived similarity are important for narrative persuasion, and that it should be kept on the research agenda of health communication.
Fear appeals are frequently used in health communication, for example in anti-smoking campaigns. Of the different theoretical models that predict and explain how fear appeals work, the Extended Parallel Process Model (EPPM; Witte, 1992) is probably used most often. However, most propositions of the EPPM were not explicitly tested, or received mixed empirical support (Popova, 2012). To clarify the relationships between the variables of the EPPM, four of the EPPM's propositions were tested by performing correlational and mediation analyses. The results (n = 116) show that a large part of the relationships between the concepts of the EPPM and the outcomes of fear appeals differ from what the EPPM claims: threat and intention did not prove to be related, threat did not mediate the effect of fear on intention, and fear did not prove to influence the fear control responses. The findings from this study raise questions regarding the appropriateness of the EPPM.
Objectives:This study compared the effects of two types of health warnings on cigarette packages: 'narrative visual warnings', showing an image portraying people plus a corresponding slogan that could evoke a story-like interpretation, and 'non-narrative visual warnings' with non-narrative content (i.e. body parts). Moreover, the mechanisms underlying the effects of these health warnings were explored. Design: A within-participants experiment was conducted comparing narrative and non-narrative visual warnings. Path analyses were performed to investigate the relationship between the narrative concepts transportation and identification, the emotions evoked by the health warning and the perceived effectiveness of the message. Method: Participants (N = 200) were presented with one narrative warning and one non-narrative warning. After each warning, they answered questions on narrative perception, transportation, identification, emotions and perceived effectiveness. Results: The narrative warnings were seen as more story-like than the non-narrative warnings. There was a statistical trend for narrative warnings to be perceived as more effective than the non-narratives. The narrative warnings caused more transportation, fear, sadness, compassion and anger; the non-narrative warnings evoked more disgust and surprise. For the narrative warnings, both narrative concepts of transportation and identification were directly related to perceived effectiveness, and also indirectly via sadness. For the non-narrative warnings, transportation was related to perceived effectiveness, both directly and indirectly via disgust. Conclusion: Seeing a story in a still picture with a slogan helps to increase the effectiveness of the antismoking message. Both narrative and non-narrative visual warnings may persuade receivers directly, but also by the evoking of emotions, although the specific emotions responsible for the persuasive effects may differ.

Does a more or less sympathetic protagonist influence transportation of the reader? Two new replication studiesThree previous studies into presenting a protagonist in a story as more or less sympathetic have not provided a clear picture of the effects that the portrayal of the protagonist may have on transportation, and via transportation on story-consistent beliefs. Results from a first study (N = 83) by De Graaf and Hustinx (2015) suggest that the way the protagonist is portrayed ‐ as sympathetic, unsympathetic or neutral ‐ influences the extent to which readers are transported into a story. No significant effects on beliefs of the readers were found, however. In a direct replication study (N = 79) and in a conceptual replication study (N = 81), Jansen, Nederhoff, and Ooms (2017) found results that supported the hypotheses from the original study to a limited extent. In view of the relatively small numbers of participants in these three studies and the resulting limited power of the statistical tests two new, larger-scaled replication studies were conducted. A direct replication study was performed (N = 238) with the same versions of the story as used in the original study, and also a conceptual replication study (N = 248) with three versions of a new story. Again, the hypotheses from the original study were supported to a limited extent. A meta-analysis of all five studies revealed a large indirect positive effect of story version on transportation via empathy, when comparing the versions with a sympathetic protagonist with the versions with an unsympathetic protagonist. When comparing the neutral story versions with the versions with an unsympathetic protagonist, the meta-analytic indirect effect was medium sized. Other than what the Affective Disposition Theory (Raney, 2004; Zillmann, 1994; 2006) claims, the story versions with a neutral protagonist did not lead to an absence of emotional responses. Furthermore, the outcomes add to the Transportation-Imagery Model (Green & Brock, 2002; Van Laer, De Ruyter, Visconti, & Wetzels, 2014). While this model does not include concrete suggestions of story characteristics that lead to transportation, our studies show that a protagonist who is portrayed as sympathetic may contribute to the level of transportation that readers experience, be it indirectly through empathy.
