Implementation Intention Planning Guide for FIT Colon Cancer Screening

Fecal immunochemical tests (FIT) are a primary method of screening for colorectal cancer (CRC). Implementation intention planning involves encouraging completion or eliminating barriers for the participant to make a plan to complete a behavior or activity. This randomized control study seeks to answer whether the addition of an implementation intention guide impacts behaviors when completing FIT screening. The primary objective includes determining if the implementation intention guide increases completion rate of screening FIT. The secondary objectives is whether this intervention decreases the lab sample rejection rate and reduces the duration between sample collection and laboratory receipt/evaluation of screening FIT.
