Arm Description

After reading a standard CDC HPV vaccine message, participants will interact with a chatbot designed to deliver personalized HPV vaccine messages (i.e., tailored to their personalities).

After reading a standard CDC HPV vaccine message, participants will interact with a chatbot designed to deliver HPV vaccine messages, which are not tailored to their personalities.

Participants will read a standard CDC HPV vaccine message without interacting with any chatbot that delivers additional messages.

Outcomes

Primary Outcome Measures

Attitudes toward HPV vaccination

Participants' attitudes toward HPV vaccination will be measured by seven questions such as ""The HPV vaccine is beneficial for adolescents."

Intentions toward HPV vaccination

Participants' intentions toward vaccinating their children against HPV will be measured by three questions such as "I am likely to get my child/children the HPV vaccine."

Secondary Outcome Measures

Ratings of the Chatbot

Participants in the chatbot conditions will rate the chatbot on a number of characteristics such as engagingness, relevance, and trustworthiness.

Brief 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.
