However, adherence rates and factors influencing participation are not well characterized. This study aimed to validate a tool to determine risk perception of CRC and GC and also of endoscopy-related complications.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods<\/jats:title>\n            <jats:p>A questionnaire in CRC risk perception based on the Health Belief Model was used. Forward\/backward translation (English-Portuguese) and cultural adaptation were performed. After revision by a panel of experts, the questionnaire was adapted to target GC risk perception and perceptions towards endoscopy-related complications. The final version of the questionnaire (PERCEPT-PREVENT tool) was applied to 44 individuals, through telephonic interview, at enrolment and at intervals \u22643 weeks. Test\u2013retest reliability and agreement were assessed.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Almost perfect reliability between test and retest was obtained for CRC symptom knowledge score (ICC = 0.88), risk factor knowledge score (ICC = 0.89), and perceived severity (ICC = 0.84). At least moderate agreement between test and retest was obtained for GC symptom knowledge score (ICC = 0.94), risk factor knowledge score (ICC = 0.92), and perceived severity (ICC = 0.58). Test-retest reliability was assessed for barrier domains [faecal occult blood test ICC = 0.63; colonoscopy ICC = 0.79; upper GI endoscopy (UGIE) ICC = 0.83]. A total of 91% and 98% of participants gave the same answer in the test and retest for preferred method of CRC screening and intention to undergo UGIE for GC screening combined with a screening colonoscopy, respectively.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Discussion<\/jats:title>\n            <jats:p>PERCEPT-PREVENT is a valid and reliable tool
