Impact of cardiovascular risk visualization on motivation to self-manage young-onset type 2 diabetes
Authors' conclusion
Lifetime risk visualizations, especially bar graphs, are more accessible and emotionally evocative in potentially motivating self-management of YOD than other visualizations.
Study context
- Population
- Adults with young-onset T2D (YOD; age at diagnosis <40 years, disease duration <10 years), Ontario, Canada; 54.8% women, mean age 37.5 years
- Participants
- 31 adults
- Comparison
- 6 cardiovascular risk visualizations
- Outcome
- Accessibility, credibility and emotional responses to visualizations
Methodological detailssemi-structured interviews, linear regression
- Semi-structured interviews
- Linear regression
Main finding
As reported in the abstract
- Lifetime risk bar graph and icon array: highest accessibility vs other visualizations
- P = 0.008
- Lifetime risk bar graph and icon array: similarly high credibility vs other visualizations
- P = 0.1
- Lifetime risk bar graph and icon array: highest negative emotion vs other visualizations
- P = 0.004
- Lifetime risk bar graph and icon array: similar positive emotion vs other visualizations
- P = 0.6
Further findings
Motivation (interviews)
- Lifetime risk visualizations evoked urgency or fear, which strongly enhanced motivation
Accessibility and credibility by numeracy and graph literacy
- Only the lifetime risk bar graph had high accessibility and credibility scores across all levels of numeracy and graph literacy
Graph literacy and positive emotion
- Graph literacy was negatively associated with positive emotion
