Summary
Computer-based health risk appraisals (HRAs) did not differ between batch and interactive formats. While men showed a tendency to adjust risk ratings, overall health knowledge did not improve post-appraisal.
Area of Science:
- Health Informatics
- Preventive Medicine
- Behavioral Science
Background:
- Computer-based health risk appraisals (HRAs) are tools for patient education and behavior change.
- Evaluating the effectiveness of different HRA formats is crucial for optimizing patient engagement and outcomes.
Purpose of the Study:
- To compare user evaluations of batch versus interactive computer-based HRAs.
- To assess changes in health risk perception and knowledge following HRA completion.
Main Methods:
- 83 patients completed one of two HRA formats (batch or interactive) and questionnaires on health risks and knowledge.
- 65 patients repeated the HRA and questionnaire after three months to assess follow-up changes.
Main Results:
- No significant differences were found in user satisfaction, intent to change behavior, or learning between batch and interactive HRA formats.
- Initially, 48% of individuals accurately estimated their health risks; this improved to 80% for men and 55% for women at follow-up.
- Men tended to adjust their risk perception towards HRA estimates, while specific knowledge of causes of death did not improve.
Conclusions:
- Both batch and interactive HRA formats are equally effective in user evaluation and learning.
- HRAs may influence risk perception, particularly in men, but do not consistently enhance specific health knowledge.
