To evaluate the effectiveness of an online, culturally tailored educational video in improving breast cancer knowledge, psychosocial constructs, and screening intentions among a predominantly Hispanic population. A pragmatic pre–post trial was conducted between August 2020 and July 2021 across the U.S., with focused outreach in a Hispanic-majority border city. Participants aged 21–78 years were recruited through community health workers, social media, and partner organizations. The 12-min bilingual video, guided by the Health Belief Model and Social Cognitive Theory, addressed breast cancer epidemiology, screening guidelines, and cultural misconceptions. Surveys administered before and after the intervention measured knowledge, perceived susceptibility, perceived benefits, perceived barriers, self-efficacy, and screening intentions. Paired t -tests or Wilcoxon signed-rank tests assessed pre–post differences ( p ≤ 0.05). Of 200 individuals who accessed the survey, 167 (83.5%) completed both assessments. Participants' mean age was 45.4 years (SD = 9.8); most were female (95.8%) and Hispanic/Latino (69.5%). Post-intervention analyses showed significant improvements in breast cancer knowledge (+7%; p < 0.002), perceived benefits (+4%; p < 0.02), self-efficacy (+4.5%; p < 0.0004), and screening intention (+8.1%; p < 0.01). This study demonstrates the utility of a brief, theory-informed, bilingual mHealth video to address breast cancer screening disparities in Hispanic/Latina women. The culturally tailored digital format supports scalability and accessibility in underserved communities. A short, culturally adapted video improved breast cancer knowledge, self-efficacy, and screening intentions, suggesting potential for broader public health integration. • mHealth video improved breast cancer knowledge in Hispanic/Latina women. • Education increased self-efficacy and mammography screening intention. • Health Belief Model outcomes support culturally tailored interventions. • Digital, bilingual tools may reduce screening disparities in underserved groups.
