Brief summary

This pilot trial studies how well a mobile health (mHealth) human papillomavirus (HPV) vaccine intervention works in increasing HPV vaccine coverage among young adult gay and bisexual men. Giving young men information about the HPV vaccine and the importance of vaccination may encourage them to get the HPV vaccine.

Detailed description

PRIMARY OBJECTIVES: I. Pilot test a mobile health (mHealth) HPV vaccine intervention for young gay and bisexual men to establish feasibility and acceptability. II. Obtain preliminary efficacy data on whether the mHealth HPV vaccine intervention increases HPV vaccine initiation compared to the control group. SECONDARY OBJECTIVES: I. Examine whether the mHealth HPV vaccine intervention affects secondary outcomes compared to the control group. OUTLINE: Patients are randomized to 1 of 2 groups. GROUP I (CONTROL): Patients receive standard information about HPV and HPV vaccine, such as the vaccine information statement (VIS), on a mobile-friendly website study portal. GROUP II (INTERVENTION): Patients receive the mHealth HPV vaccine intervention consisting of content about HPV and HPV vaccine on the study portal for 15 minutes and vaccination reminders sent by the portal via text or e-mail. All patients complete a survey on the study portal at baseline, immediately after the mHealth intervention or control materials, and at 3 months and 7 months thereafter for about 10-15 minutes each.

Design outcomes

Primary

Measure	Time frame	Description
Acceptability will be established by examining participant satisfaction with study materials	Up to 7 months	Linear regression will be used and usage data and satisfaction with vaccination reminders (intervention group only) will be descriptively examined.
Feasibility established by achieving recruitment, retention, and medical record release goals	Up to 7 months	Critical parameters with point estimates and 95% confidence intervals will be estimated and tested with a two-sided alpha=.05
Receipt of 1 or more doses of HPV vaccine	Up to 7 months	Evaluated using logistic regression.

Secondary

Measure	Time frame	Description
Changes in potential mediators between study group and HPV vaccination (i.e., protection motivation theory [PMT] constructs and HPV and HPV vaccine knowledge)	Up to 7 months	Evaluated using analysis of covariance models.
Receipt of second and third doses of HPV vaccine	Up to 7 months	Evaluated using logistic regression.
