OBJECTIVE: To develop and test a novel instrument to assess public awareness of endometrial cancer symptoms and risk factors in a UK population.
METHODS: A 36-item questionnaire was developed through literature review and extraction from cancer awareness materials. The Womb Cancer Awareness Measure (WCAM) was tested for content validity in 65 self-identified female research participants and 10 endometrial cancer experts prior to UK-wide field testing using social media. Test-retest reliability was assessed over 2 weeks, construct validity was assessed by comparing womb cancer experts and non-medical academics, and sensitivity to change was assessed by comparing scores of participants who read an endometrial cancer leaflet with those given a control leaflet.
RESULTS: Fifty-two percent of the items in the test-retest reliability showed >80% agreement. Construct validity was demonstrated; endometrial cancer experts achieved higher scores (median 79 (IQR 18)) than non-medical academics (median 50 (IQR 18)) (p<0.001). The WCAM was sensitive to change; volunteers who read an endometrial cancer leaflet showed greater awareness (median 73 (IQR 9)) than those who read the control leaflet (median 59 (IQR 9)) (p<0.001). Knowledge of endometrial cancer red flag symptoms and risk factors was poor in the 847 UK-based participants.
CONCLUSIONS: Our findings support the validity and reliability of the Womb Cancer Awareness Measure in assessing public awareness of endometrial cancer. In a UK population sample, knowledge of warning symptoms and risk factors was low, highlighting the need for public awareness campaigns.
