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.

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?

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

Page 6: Study: Narratives for Health Communication

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

Message appreciation

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.

Page 9: Study: Narratives for Health Communication

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

▹ The influence of message structure on message appreciation was fully mediated by involvement and systematic processing.

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?
