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).\n\nSECONDARY AIM To investigate effects of each component on HPV vaccination outcomes and psychosocial mediators.
