How can we help people understand #risk?



Some evidence favors #iconArrays (that visualize outcome frequencies)

But what if we added a patient narrative to those #graphics?



A small experiment found #narratives actually *worsened* factual recall!

Example of icon array and individual narratives.Examples of individual narratives:

"Side effects are less important, to me... survival is most important."

"In my case, I would accept the risk of long-term side effects.
Because the flipside was — if I hadn't gotten treatment - I may no longer be sitting in this chair"

"In the end, your health comes before everything, right?! think I would take any chance to get better"The two-arm experimental design: 

20 participants
Arm 1: Version with patient narratives (10 participants)
Arm 2: Version without patient narratives (10 participants)

13/20 (former) cancer patients
2/13 breast cancer


Protocol: Semi structured, think-aloud interviews

Measures:
Knowledge test (6/20 scores "Low") 
Newest Vital Sign - DutchThe group who also received narratives had lower factual recall 4.8 vs 6.8 out of 9, ANCOVA B = -2.14, p = 0.002)
