"Hey, that could be me": The role of similarity in narrative persuasion.

ABSTRACT: 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.

Project description:BackgroundGlobal health diplomacy (GHD) has become an important field of investigation due to health concerns increasingly entering the foreign policy domain. Much of the existing academic writing focuses on North-South cooperation in global health, and emphasizes the role of security and economic interests by Northern countries as drivers of GHD. Chile presents a favourable environment for an expanded involvement in future GHD activities. However, there is little knowledge about what has been driving Chile's integration of health into foreign policy, and little effort to appropriate knowledge from international relations theories to better theoretically grasp the emergence of GHD.MethodsTo fill this knowledge gap, we conducted a narrative literature review of the driving forces behind Chile's integration of health into foreign policy. Drawing on a popular analytical framework used in international relations scholarship, we identified driving forces of the integration of health into Chile foreign policy at three levels of analysis.ResultsAt the international/global level of analysis, the main driving forces were related to national security concerns and compliance with regulations of international organizations. At the regional level, GHD was driven by a commitment to regional solidarity through mutually beneficial cooperation in response to neoliberal reforms; health coordination in emergencies; and protection of indigenous peoples. Finally, at the domestic level, drivers identified include economic interests of various productive sectors and how health regulations might impact those; the high degree of social inequity which impacts on access to healthcare; and management of natural disasters.ConclusionHealth actions in the context of international relations in Chile are still mainly motivated by more traditional foreign policy interests rather than by a desire to satisfy health needs per se. This seems to conform with findings of existing GHD scholarship that emphasize the importance of security and economic interests as driving forces of GHD, and how health is often appropriated instrumentally within foreign policy settings to achieve other goals. But the review also reveals that in the context of South-South cooperation (and regional health diplomacy), solidarity and normative considerations can be important driving forces as well. Finally, the review demonstrates that there has been an evolution from chiefly domestically focused health policies (e.g. maternal and child nutrition treatment) towards internationally inspired integrated policies (e.g. maternal and child nutrition promotion aligned with international guidelines).

Project description:Heart failure (HF) accounts for a tremendous burden on health care systems and the society. Since the landmark PARADIGM-HF trial, sacubitril/valsartan, the first in the class of angiotensin receptor neprilysin inhibitor (ARNI) showed superiority to enalapril in patients with HF with reduced ejection fraction (HFrEF). We performed a narrative literature review, hand-searched the reference lists of included articles and relevant reviews. Inhibition of neprilysin increases bradykinin, natriuretic peptides and adrenomedullin levels counteract the neurohormal activation that leads to sodium retention, vasoconstriction, and cardiac remodeling. In PARADIGM-HF the primary outcome of CV death or HF hospitalization was reduced 20% in the ARNI group (HR 0.80, P<0.001) similar to mortality due to cardiovascular cause (HR 0.80, P<0.001) in patients with HFrEF, rendering a number needed to treat of 21 patients. This effect was consistent across subgroups. The safety of starting ARNI inpatient once the acute decompensation of HF is stabilized was demonstrated in PIONEER-HF trial. With willingness-to-pay thresholds commonly acceptable in the United States, sacubitril/valsartan is likely to be cost effective, which might not be in other health systems. Although its safety has been reassured in some clinical trials, common side effects are hypotension, worsening kidney function, hyperkalemia and angioedema. In HFpEF (PARAGON-HF), sacubitril/valsartan showed decrease in the level of the cardiac biomarkers, with improve functional NYHA and decrease in hospitalizations, predominately in women and patients with borderline ejection fraction. Some ongoing studies aim to demonstrate the effects of ARNI in acute coronary syndrome, stable ischemic heart disease, advanced HF, mitral regurgitation, aortic impedance and pulmonary hypertension. In conclusion, sacubitril/valsartan has proven to be an effective addition to the HFrEF arsenal, with safety comparable to current standard of care. In HFpEF, it improves quality of life, particularly in women and in patients with borderline ejection fraction, with no effect on mortality.
