Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Personalized Chatbot Condition

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).

Group Type EXPERIMENTAL

Personalized Chatbot Intervention

Intervention Type BEHAVIORAL

In this intervention, participants will first see a standard CDC HPV vaccine message. After that they will be invited to interact with a chatbot designed to deliver additional HPV vaccine messages, which are tailored to their personalities.

Non-Personalized Chatbot Condition

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.

Group Type EXPERIMENTAL

Non-Personalized Chatbot Intervention

Intervention Type BEHAVIORAL

In this intervention, participants will first see a standard CDC HPV vaccine message. After that they will be invited to interact with a chatbot designed to deliver additional HPV vaccine messages, which are not tailored to their personalities.

No Chatbot Control Condition

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

Group Type ACTIVE_COMPARATOR

No Chatbot Control

Intervention Type BEHAVIORAL

In this intervention, participants will see a standard CDC HPV vaccine message only and will not interact with any chatbot.
