Feasibility, Acceptability and Preliminary Efficacy of a Personalised Behavioural Intervention to Improve Adherence to Dietary and Lifestyle Cancer Prevention Recommendations in Adults Attending Breast and Colorectal Cancer Screening Programmes: A Three-Arm Randomised Pilot Trial (CANVIA)
The aim of this clinical trial is to find out whether CANVIA can help adults improve dietary and lifestyle habits related to cancer prevention. CANVIA is a personalised programme based on cancer prevention recommendations from the World Cancer Research Fund and the American Institute for Cancer Research (WCRF/AICR). The programme uses a short questionnaire, called the WCRF/AICR Screener, to give each participant personalised feedback.
This study will include adults aged 50 to 69 years who take part in breast or colorectal cancer screening programmes in Palma, Mallorca, Spain. The study will assess whether participants can complete the CANVIA study procedures and use the programme for six months, whether the CANVIA app and, where applicable, the professional support are acceptable and easy to use, and whether there are early signs that CANVIA may help participants follow cancer prevention recommendations more closely.
Before the pilot trial starts, a small first phase with about 20 to 30 participants will test the study procedures and the mobile app. After this, 132 participants will be assigned by chance to one of three groups. One group will receive only a personalised written report at the start of the study. A second group will use the CANVIA mobile app for six months. A third group will use the CANVIA mobile app and also receive support from health professionals for six months.
Participants will complete study assessments at the start of the study, after three months and after six months. Participants in the app groups will receive personalised messages, educational resources and weekly goals or challenges. Some participants from the app groups will also be invited to take part in focus groups at the end of the study to share their experiences and suggestions.
