What was measured

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.

Groups in this outcome

Personalized Chatbot Condition

After reading a standard CDC HPV vaccine message, participants interacted with a chatbot designed to deliver personalized HPV vaccine messages (i.e., tailored to their personalities). Personalized Chatbot Intervention: In this intervention, participants first saw a standard CDC HPV vaccine message. After that they were invited to interact with a chatbot designed to deliver additional HPV vaccine messages, which were tailored to their personalities.

Non-Personalized Chatbot Condition

After reading a standard CDC HPV vaccine message, participants interacted with a chatbot designed to deliver HPV vaccine messages, which were not tailored to their personalities. Non-Personalized Chatbot Intervention: In this intervention, participants first saw a standard CDC HPV vaccine message. After that they were invited to interact with a chatbot designed to deliver additional HPV vaccine messages, which were not tailored to their personalities.

No Chatbot Control Condition

Participants read a standard CDC HPV vaccine message without interacting with any chatbot that delivers additional messages. No Chatbot Control: In this intervention, participants saw a standard CDC HPV vaccine message only and did not interact with any chatbot.
