Knowledge, attitudes and beliefs regarding colorectal cancer screening among ethnic minority groups in the Netherlands - a qualitative study

Background: Research has shown that ethnic minority groups are less likely to participate in colorectal cancer (CRC) screening than the majority population and hence less likely to be diagnosed at an early stage when treatment is potentially more successful.

Objective: To explore knowledge, attitudes and beliefs regarding CRC and CRC screening among ethnic minority groups in the Netherlands.

Design: We conducted qualitative interviews with 30 first-generation immigrants born in Turkey, Morocco and Surinam. We based the topic guide on the health belief model. Framework analysis was used to analyse our data.

Results: Although knowledge of CRC and CRC screening was limited, all respondents felt susceptible to CRC. CRC screening was perceived to mainly benefit those individuals with poor health and symptoms. Although most respondents had a positive attitude towards CRC screening, knowledge about its potential harms was limited and self-efficacy to participate was low. Adult children acted as important mediators in providing access to information. The language barrier and low literacy formed serious barriers to informed participation in CRC screening.

Conclusion: To ensure that all eligible individuals, including ethnic minority groups, have equal opportunities to informed participation in screening, targeted communication strategies should be developed, such as oral and visual channels, and face-to-face communication in the mother tongue. This will help ethnic minority groups to make an informed decision about participation in CRC screening.
