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.

Conditions

Cervical Cancer; Anal Cancer; Penile Cancer

Outcome Measures

Primary Outcomes (2)

• Attitudes Toward HPV Vaccination

  Participants' attitudes toward HPV vaccination were measured by seven questions such as "The HPV vaccine is beneficial for adolescents." The responses were recorded on 1 (strongly disagree) to 5 (strongly agree) scales. Final score was the average of all 7 questions.

  baseline posttest (test took approximately 5 minutes to complete)

• Intentions Toward HPV Vaccination

  Participants' intentions toward vaccinating their children against HPV were measured by three questions such as "I am likely to get my child/children the HPV vaccine." Responses were indicated on 1 (strongly disagree) to 5 (strongly agree) scales. The final score was the average of the three questions.

Study Arms (3)

Personalized Chatbot Condition

EXPERIMENTAL

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).

Behavioral: Personalized Chatbot Intervention

Non-Personalized Chatbot Condition

EXPERIMENTAL

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.

Behavioral: Non-Personalized Chatbot Intervention

No Chatbot Control Condition

ACTIVE COMPARATOR

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

Behavioral: No Chatbot Control

Interventions

Personalized Chatbot Intervention 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.

Personalized Chatbot Condition

Non-Personalized Chatbot Intervention 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.

Non-Personalized Chatbot Condition

No Chatbot Control BEHAVIORAL

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

No Chatbot Control Condition

Limitations and Caveats

The online survey-experiment may not fully reflect how individuals typically encounter health messages in the real world. There is concern about ecology validity. Also the long-term effects of message exposure were not determined.
