Intervention tailoring for Chinese American women: comparing the effects of two videos on knowledge, attitudes and intentions to obtain a mammogram

Abstract

This study utilized data from an ongoing randomized controlled trial to compare a culturally tailored video promoting positive attitudes toward mammography among Chinese immigrant women to a linguistically appropriate generic video and print media. Intervention development was guided by the Health Belief Model. Five hundred and ninety-two immigrant Chinese Americans from the metropolitan Washington, DC, and New York City areas completed telephone interviews before and after intervention. Changes in knowledge, Eastern views of health care (fatalism and self-care), health beliefs (perceived susceptibility, severity, benefits and barriers) and screening intentions were measured. Results showed that both videos improved screening knowledge, modified Eastern views of health care, reduced perceived barriers and increased screening intentions relative to print media (all P < 0.05). The generic video increased screening intention twice as much as the cultural video, although subgroup analysis showed the increase was only significant in women aged 50-64 years. Only Eastern views of health care were negatively associated with screening intentions after adjusting for all baseline covariates. These data suggest that a theoretically guided linguistically appropriate video that targets women from various ethnic groups is as efficacious in modifying attitudes toward mammography screening as a video that is exclusively tailored for Chinese immigrant women.
