We will present our study which assessed the short-term effects of providing personalised cancer risk information in an online format on cancer risk beliefs and self-reported behaviour. We randomised 1018 participants, recruited through the online platform Prolific, to either a control group receiving cancer-specific lifestyle advice or one of three intervention groups receiving their computed 10-year risk of developing one of the five most common preventable cancers either as a bar chart, a pictograph or a qualitative scale alongside the same lifestyle advice.
The software package Gorilla was used for randomisation and delivery of risk information as well as the pre and post-intervention questionnaires. The primary outcome was change from baseline in computed risk relative to an individual with a recommended lifestyle (RRI) at three months. Secondary outcomes included: health-related behaviours, risk perception, anxiety, worry, intention to change behaviour, and a newly defined concept, risk conviction. We will briefly present the trial findings as well as discussing the benefits and challenges of our chosen online methods.
