Study: NCT06367699

Intervention type: BEHAVIORAL
Group type: ACTIVE_COMPARATOR
Intervention: Usual Care
Description: Parent/guardian and adolescent participants will not receive the ECA-HPV system intervention. A survey will be given via REDCap to the parent/guardian and adolescent participants at baseline, after the first well child clinic visit, and after the second well child clinic visit to assess self-reported vaccination attitudes and behaviors. Adolescent participants will receive usual care.

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: ECA-HPV App with Clinic Notification and Adolescent Functions Disabled
Description: Parent/guardian participants will interact with the ECA-HPV smartphone-based system over a period of \~16 months. The ECA-HPV is designed to interact with parents/guardians to increase vaccine acceptability prior to the clinic visit. A survey will be given via REDCap at baseline, after the first well child clinic visit, and after the second well child clinic visit to both the parent/guardian and adolescent to assess self-reported vaccination attitudes and behaviors. Parent/guardian participants will also be asked questions about the ECA-HPV app. The clinic notification and adolescent functions of the complete ECA-HPV app are disabled. Adolescent participants will receive usual care.

Intervention: ECA-HPV App with Clinic Notification Function Enabled
Description: Parent/guardian participants will interact with the ECA-HPV smartphone-based system over a period of \~16 months. The ECA-HPV is designed to interact with parents/guardians to increase vaccine acceptability prior to the clinic visit. A survey will be given via REDCap at baseline, after the first well child clinic visit, and after the second well child clinic visit to both the parent/guardian and adolescent to assess self-reported vaccination attitudes and behaviors. Parent/guardian participants will also be asked questions about the ECA-HPV app and the clinic notification feature. The clinic notification is enabled on the parent/guardian ECA-HPV app, however, the adolescent does not have access to the adolescent ECA-HPV app. Adolescent participants will receive usual care.

Intervention: ECA-HPV App with Adolescent Function Enabled
Description: Parent/guardian participants will interact with the ECA-HPV smartphone-based system over a period of \~16 months. The ECA-HPV is designed to interact with parents/guardians to increase vaccine acceptability prior to the clinic visit. A survey will be given via REDCap at baseline, after the first well child clinic visit, and after the second well child clinic visit to both the parent/guardian and adolescent to assess self-reported vaccination attitudes and behaviors as well as ECA-HPV app use and satisfaction. The adolescent function is enabled, however, the clinic notification function is disabled. Thus, the ECA-HPV system app will have an adolescent-facing feature for adolescent participants to engage with the agent. Adolescent participants will receive usual care and will be able to engage with the adolescent version of the ECA-HPV app throughout the duration of the study.

The complete ECA-HPV app includes the parent version and adolescent versions of the ECA-HPV app. Both versions have the clinic notification feature enabled. Adolescent participants will receive usual care and can engage with the adolescent version of the ECA-HPV app throughout the study.
