Motivational Interviewing for Colonoscopy

Compared to other racial groups, African Americans have the highest colorectal cancer (CRC)
morbidity and mortality rates. Screening colonoscopy can aid in the early detection and
prevention of CRC. A motivational interviewing (MI) intervention holds strong promise to
increase African Americans' screening colonoscopy adherence and, by doing so, decrease CRC
disparities. There is a great need to conduct a randomized clinical trial (RCT) that tests
the efficacy of an MI intervention to increase screening colonoscopy adherence in African
Americans. The first critical and necessary step in this line of research is to pilot test
such an RCT.

Objective/hypotheses: The primary objective of the proposed study is to conduct pilot
testing for a future RCT which will formally test the effects of MI on screening colonoscopy
adherence in African Americans. The results from this pilot study will directly inform the
development of a future RCT.

Specific aims: 1) To estimate the magnitude of the MI intervention effect size; and 2) To
estimate the magnitude of the mediation effect sizes (drawn from Self Determination Theory).
