Experimental: Interaction with a VHA with voice
A virtual health assistant computer-generated doctor who will have a conversation with you.
Behavioral: Dialectal Features Varied
Participants will randomized to interact with a VHA that speaks either Standardized American English, a low level of African American English, or a high level of African American English
Behavioral: Video Intervention
Participants will randomized to either receive a video introduction from the voice actor or receive no introduction
Active Comparator: Interaction with a VHA without voice
A virtual health assistant that will consist of photos of the computer-generated doctor with text that will guide you through the interaction. No voice will accompany the photos or text.
Behavioral: VHA with no voice
virtual health assistant that will consist of photos of the computer-generated doctor with text that will guide you through the interaction. No voice will accompany the photos or text.
- Credibility score [ Time Frame: 6 months ]The primary outcome in the current pilot study is credibility score. We expect that source credibility is the mechanism through which intentions to screen will be strengthened. Credibility score will be determined on a Source Credibility Scale (McCroskey & Teven, 1999) from 1 to 7, 1 being "Credible" and 7 being "Not Credible". Lower scores indicate VHA credibility. Higher scores indicate a lack of VHA credibility.
