AbstractIntroduction:
Worldwide, colorectal Cancer (CRC) is a leading cause of cancer mortality. CRC screening has been proven effective to reduce its associated mortality, and a high participation rate remains to be a significant performance indicator that exerts a direct impact on program success. Unfortunately, screening uptake tends to be low in different populations
over the globe. We aimed to examine whether the Theory of Planned Behaviour (TPB) can predict the uptake of CRC screening that could further inform new strategies in the promotion of screening uptake in the general population.

Methods:
A population-based telephone survey is being conducted from 2017 to 2018. Individuals aged 61-70 years are randomly recruited based on a simple random sampling approach. We use the telephone directory that consists of a vast majority of land-based telephone lines as the sampling frame. A total of 4,800 eligible respondents will be recruited, consisting of 2,400 participants and 2,400 non-participants of the government-subsidized CRC screening programme. A questionnaire validated by an expert panel is used to measure each component of TPB, namely: (1). the attitudes towards CRC screening; (2). normative beliefs; (3). perceived behavioural control and (4). intention for each participant. The association between CRC screening uptake and the variables pertinent to TPB will be
analysed by a binary logistic regression adjusted for age, sex, education, and income level. Anticipated results: We hypothesized that high perceived behavioural control, high intention for CRC screening and positive attitude towards CRC screening were significantly associated with CRC screening uptake.

Significance:
We aim to show that the variables pertinent to the TPB could successfully predict the uptake of CRC screening. If this is the case, promotion of CRC screening based on enhancing perceived behavioural control as well as behavioural intention could be effective in increasing screening uptake. Further studies are needed to establish a cause-and effect
relationship between these variables and uptake, as well as to evaluate the cost effectiveness of such interventions.
