Abstract
Background: Interactive multimedia computer programs (IMCPs) show promise as a way of delivering
personally tailored (PT) information to enhance cognitive mediators of health behavior and improve patient
outcomes. However, it is unclear whether PT IMCPs can be deployed in primary care offices to increase
cancer screening uptake and eliminate ethnic disparities in uptake by providing PT information in each user's
preferred language. Aims/Hypotheses: We will compare changes in CRC screening cognitive mediators (self-
efficacy, perceived barriers, and readiness) and uptake resulting from an IMCP PT to enhance the key
cognitive mediators and targeted to patients' self-identified ethnicity - with changes resulting from a non-
tailored "electronic leaflet" control IMCP. The experimental and control IMCPs will each be offered in English
and Spanish versions. We hypothesize that, compared with the appropriate control condition (English,
Spanish, or both combined): (1) the English version of the PT IMCP will enhance the cognitive mediators of
CRC screening behavior for English-speaking Hispanics and non-Hispanics; (2) there will be similarly favorable
changes in these mediators for Hispanics using the Spanish version of the PT IMCP; (3) deployment of the PT
IMCP will provide evidence of elimination of disparities in CRC screening between Hispanic and non-Hispanic
subjects via its relative impact on the cognitive mediators in these groups; and (4) the PT IMCP (English and
Spanish combined) will increase CRC screening uptake in Hispanics and non-Hispanics (considered
separately) via changes in the cognitive mediators. Methods: Randomized controlled trial of 2 groups,
comparing a PT (to the cognitive mediators) CRC screening IMCP offered in both English and Spanish
versions and deployed before a primary care office visit with a non-tailored "electronic leaflet" CRC screening
IMCP (control) also offered in both English and Spanish. Screening methods targeted will be fecal occult blood
testing, flexible sigmoidoscopy, and colonoscopy. Primary outcomes will be CRC screening uptake, self-
efficacy, perceived barriers, and readiness. Implications: Our findings will determine whether an IMCP that is
PT to cognitive mediators of screening behavior and deployed in primary care offices prior to previously
scheduled visits can activate patients of various ethnicities to undergo CRC screening. They may also suggest
a promising, portable method of reducing disparities in CRC (and other) screening uptake between Hispanic
and non-Hispanic individuals. Project Narrative: Our findings will determine whether an interactive multimedia computer program that is
personally-tailored to cognitive mediators of screening behavior and deployed in primary care offices prior to
previously scheduled visits can activate patients of various ethnicities to undergo colorectal cancer screening.
They may also suggest a promising, portable method of reducing disparities in colorectal cancer (and other)
screening uptake between Hispanic and non-Hispanic individuals.
