Scientific titleA randomised controlled trial of a brief psychological intervention to increase the uptake of colorectal cancer screening in adults aged 50-74 years in Scotland
Study acronymARTICS
Study objectivesIn this large-scale, questionnaire-based study we will test whether asking people whether they would later regret not returning their Faecal Occult Blood Test (FOBT) screening kit for colorectal cancer increases FOBT returns.

Research questions:
1. Does a brief, theory-based anticipated regret (AR) intervention lead to a significant increase in the uptake of FOBT colorectal cancer screening in Scotland?
2. Is the effect observed equally across genders and social deprivation levels?
3. Is the effect a general consequence of the 'mere measurement effect' (i.e. completing a questionnaire about the topic in question may increase response) or is it a specific consequence of AR?
4. Is uptake influenced by participants' health beliefs, in particular anticipated regret, disgust, intention, perceived benefit and health locus of control?

Health condition(s) or problem(s) studiedColorectal bowel cancer screening
InterventionWe will adopt a simple, between-groups, three-arm prospective randomised controlled trial design:
1. Control: no questionnaire
2. HLOC: Health Locus of Control questionnaire
3. AR: Anticipated regret questionnaire
Participants who are allocated to the questionnaire arms (2 & 3) will be told that we are studying the effects of attitudes towards screening, and how they influence FOBT returns.

Control arm
Participants in the control arm will be sent the standard pre-notification letter, according to current practice.

HLOC Intervention
Those randomly allocated to the HLOC group will also be sent the pre-notification letter plus the 18-item Health Locus of Control scale. HLOC participants will also be asked to rate their perceived disgust (ick factor) and perceived benefit of returning their FOBT using modified versions of the ick-factor scale and perceived benefit scales from our previous research with organ donation, as well as rating their intention of returning the FOBT test, all using simple scales. Participants will be asked to return this brief questionnaire in a stamped addressed envelope that will be provided. We predict that high scores on chance HLOC will predict lower return rates, as this taps a fatalistic view of health and health outcomes.

AR Intervention
Those allocated to the AR group will also be sent the pre-notification letter and will be asked to complete the same HLOC/ick/perceived benefit questionnaire as the HLOC group with 2 additional AR questions. The first of these additional questions will be placed as the very first question of the survey ('If I did not complete and return my test kit I would later feel regret') and the second will be placed immediately preceding the final question measuring intention to return the kit ('If I did not complete and return my test kit, I would later wish I had'). In order to make the two questionnaires identical in length, the HLOC questionnaire will have 2 filler questions added in the same location as the AR questions.
