Our outcome was self-reported mammography use six months post-intervention. Changes in key screening barriers (i.e., knowledge, cultural views, and health beliefs) pre-and post-intervention were evaluated using T-tests and linear regression models. Participants were successfully randomized. Thus, chi-square tests were used to examine group differences in screening outcomes. Results: The cultural video led to a significant 12 percentage point increase in mammography use relative to the control arm (41% vs. 29%, p=.02; baseline screening rate=0). The increased screening rate of the generic video group (38%) did not significantly differ from that of the control group. The cultural video also significantly increased mammography use among low-acculturated and never screened women relative to the control arm (39% vs. 26%, p=.03 and 29% vs. 15% p=.056, respectively); the generic video did not. Both videos had a greater impact on improving women's knowledge, cultural, and attitudinal barriers to mammography (p<.0001) than the control arm. Conclusions: A culturally sensitive video program is relatively efficacious in increasing mammography use over a standard intervention program for Chinese women, suggesting that cultural tailoring of intervention programs is needed to promote low screening rates of this growing immigrant population.
