About this trial
The purpose of the HERO study is to leverage the Multiphase Optimization Strategy (MOST) framework to conduct a pilot trial testing four different intervention components (expert video, self-persuasion, narrative storytelling, and motivational interviewing) targeting HPV vaccination among U.S. Vietnamese.
PRIMARY AIM To assess the feasibility and acceptability of each of the four digital HERO intervention components in a pilot optimization trial using the MOST framework. Using a highly efficient design, the study team will randomize 96 Vietnamese parents of unvaccinated adolescents to receive 0 to 4 HERO components. The study team will establish the feasibility (reach, retention, adherence) and acceptability (usability, satisfaction, usefulness, cultural relevance) of each component (expert video, self-persuasion, narrative storytelling, and motivational interviewing).
SECONDARY AIM To investigate effects of each component on HPV vaccination outcomes and psychosocial mediators. The study team will examine the effects on HPV vaccination (initiation and intention) and psychosocial mediators.
