"Initiation of Colon Cancer Screening in Veterans or Start Screening Now"

"In Step 1, we will evaluate a theory-based minimal cue delivered by a letter, telephone call, or automated telephone call. Persons who do not complete CRCS in Step 1 will be randomized to Step 2 using principles of Motivation Interviewing. Step 2 also will determine whether an automated approach, telephone-linked communication (TLC), is as effective as a telephone counselor in promoting initiation of CRCS. Steps 1 and 2 together will address the important issue of the dose needed to encourage completion of CRCS."

A survey-only control arm will be compared to the experimental arm to determine whether the 3 different delivery channels are equally efficacious and cost-effective.
