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, designed to target barriers identified in study 1, using a 28 factorial design. Participants then completed the same survey used in study 1. Multivariate regression tested the effectiveness of the BCTs to modify target barriers and intentions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In study 1, 5 items were associated with intentions, namely \u201cLack of understanding that CRC can be asymptomatic,\u201d \u201cPerceived importance of screening,\u201d \u201cTransport\/travel,\u201d \u201cShared decision making and family influenced participation,\u201d and \u201cFear of pain and discomfort\u201d (all P\u2019s\u2005&amp;lt;\u2005.05).
