Summary

The goal of this project is to test the efficacy of a chatbot intervention for reducing HPV vaccine hesitancy among African American parents. An online experiment will be conducted to test the effectiveness of the chatbot intervention with African American parents. Results of this project will inform future communication interventions for reducing vaccine hesitancy among African American parents.

Detailed description

The goal of this project is to test the efficacy of a chatbot intervention for reducing HPV vaccine hesitancy among African American parents. An online survey-experiment will be conducted. In the survey-experiment, participants will first answer questions related to their attitudes toward childhood vaccines and see a brief CDC message about HPV vaccine. Then they will be directed to interact with a chatbot designed to deliver personalized HPV vaccine messages (tailored to the participant's personality) or a similar chatbot with non-personalized messages. There will also be a control condition where participants will see the brief CDC message about HPV vaccine but will not interact with any chatbot. All participants will answer questions related to their attitudes toward HPV vaccination, intentions to vaccinate their children, as well as other message response measures.

Conditions

• Cervical Cancer
• Anal Cancer
• Penile Cancer
