CHLAMYDIAIs the most common sexual desease in Europe
1 in 20 Flemish men and women are suffering from Chlamydia
Women below 24 Are at highest risk

Narratives in health communicationNarratives: A presentation of (a) concrete event(s) experienced by (a) specific character(s) in a particular setting.
Literature review: De Graaf, Sanders, & Hoeken (2016) On average, narratives are more effective
compared to non-narratives Also in an explicit persuasive context Can positively stimulate attitudes,
message engagement and behavior.
Simone Krouwer - University of Antwerp
Difference in effectiveness among health narratives...Knowledge gaps
What is the influence of message structure? Narrative-first versus persuasive message first
What is the influence of context when two narratives are compared? Editorial versus commercial context Facebook?
Simone Krouwer - University of Antwerp
Literature review: contextBehavioral Journalism literature: Journalistic format = most trustworthy and receives more attention
(McAlister, 1995)
Intentional exposure theory Readers are more likely to pay attention to editorial messages
Spill-over effect of context Positive evaluations of context can spill-over on the health advertisement
Simone Krouwer - University of Antwerp
Context Hypotheses:
A health narrative in a native advertisement format from an editorial source (Flair) will
generate more
(a) Attention and
(b) Message appreciation
Compared to an native advertisement directly provided by a health organization.

Literature review: message structureNarratives…
Are less likely to activate an ‘advertising schema (Kim and Hancock, 2016)
Readers can get immersed into the story
Activate a less critical, narrative style of processing
(Wentzel, Tomczak, and Herrmann, 2010)
Persuasive Messages
Can elicit persuasion knowledge + resistance
More critical processing

Attention
A ‘health narrative-first’ message structure will lead to an increase in (a) attention, (b) Involvement, (c) systematic processing and (d) message appreciation, compared to a health-information first structure.
Context X Message structure
The context of the health narrative will moderate the effects of message structure, meaning that an editorial context will increase the positive effects of the ‘health narrative’ first message on:
▹ (a) attention▹ (b) involvement▹ (c) processing▹ (d) message appreciation

HAYES MULTIPLE MEDIATION ANALYSIS
▹ The influence of message structure on message appreciation was fully mediated by involvement and systematic processing.
.32* .36** .41**
Significant indirect bootstrap effect (N = 1000): (B= .05, SE=.03 , 95% CI = .007- .114)
* = p < .05
** = p < .001
DISCUSSION AND IMPLEMENTATION
Answer to knowledge gap #1: influence of message structure? It is important to start with the narrative
ELM: narrative first increase in involvement systematicprocessing positive evaluations
Answer to knowledge gap 2: influence of explicitness persuasive intent? Journalistic context not more efficient than health organisation
Less critial processing of source in health context? Trust in health organziations? Less influence of source in Facebook environment?
Thanks! Any questions?
