Effectiveness of behavior change techniques to address barriers to follow-up colonoscopy: results from an online survey and randomized factorial experiment.

ABSTRACT:

Background

Nonattendance at colonoscopy is associated with reduced colorectal cancer (CRC) survival.

Purpose

The aim of this research was to quantify barriers to colonoscopy and test the effectiveness of behavior change techniques (BCTs) to address them.

Methods

Two studies were conducted. In the first study, participants were asked to imagine their next CRC screening result was abnormal, and were presented with the standard abnormal result letter used in the English CRC Screening Programme. Participants then completed a short survey. Multivariate regression tested associations between perceived barriers and intentions. In the second study, participants were randomly presented with a modified version of the abnormal results letter, which incorporated one or more BCTs,
