Findings
Summary
This study assessed the
efficacy of a tailored, bilingual, interactive multimedia breast
cancer education intervention designed for low-income, low literacy
Latinas and delivered through touch screen kiosks at six different
clinical settings. It examined whether the technology-based intervention
was acceptable to the intended audience, and assessed changes
in breast cancer knowledge, attitudes and screening behavior.
The study population encompassed 1,197 Latina women ages 40 to
65; the majority were foreign-born, had less than eight years
of education and a weekly household income below $350.00. Participants
were randomly assigned to a control or intervention condition.
The control group served as the baseline against which post-exposure
changes in breast cancer knowledge, attitude and mammography screening
of the intervention group were assessed. Data were collected through
questionnaires and oral interviews with participants. The intervention
group exhibited higher knowledge and attitude change scores than
the control group (Chi sq., p=<. 0001). Four months after exposure,
51% of non-adherent women obtained a mammogram—a dramatic
health outcome. This robust effect size demonstrates that this
intervention overcame screening barriers and significantly increased
mammogram screening behavior. It also suggests that well-designed,
multilingual and multicultural eHealth applications can be effectively
leveraged to reduce health disparities among medically underserved
populations.
