Design outcomes

Primary

MeasureTime frame
Behavioral trust. The subjects indicate in a questionnaire whether they consider the described case to require emergency care or not. The symptom checker gives the opposite recommendation and contradicts the subjects' appraisal. Behavioral trust is calculated by coding cases in which subjects deviate from their initial opinion in favor of the symptom checker as "trusted" and coding subjects who do not deviate as "not trusted".

Secondary

MeasureTime frame
- Subjective trust - "Verbatim" representation of the symptom checker accuracy, accuracy of other people and accuracy of oneself (pre & post) - "Gist" representation of the symptom checker accuracy, accuracy of other people and accuracy of oneself (pre & post) - Intention to use - Self-perceived usefulness - Recommendation to others
