Assessing Colorectal Cancer Knowledge Among Puerto Rican Hispanics: Implications for Cancer Prevention and Control

The validity of instruments to measure knowledge in population-based cancer screening targeting individuals at average risk - A systematic review

OBJECTIVES

Relevant knowledge is essential for informed choices about (non)participation in population-based cancer screening. Many instruments have been proposed to assess residents' knowledge about cancer screening programmes but their measurement properties are unknown. This systematic review aims to identify and critically evaluate the measurement properties of instruments to measure knowledge about cancer screening in individuals eligible for population-based screening.

METHODS

A literature search was undertaken in PubMed, PsycINFO, Embase, CINAHL, Scopus and Web of Science in August 2023. The review included any study reporting one or more measurement properties of the questionnaire or sub-scale used measuring knowledge of cancer screening including breast, colorectal and/or cervical cancer screening. Studies including males aged 45 or older and females aged 20 or older were included. Two independent reviewers screened the articles and assessed the included articles using the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN).

RESULTS

We included 24 instruments, which varied in number and characteristics of items. All instruments were assessed as having an inadequate instrument development. The results of structural validity, internal consistency, criterion validity and reliability were assessed as indeterminate, while construct validity and responsiveness were assessed as sufficient.

CONCLUSION

This systematic review identified no instruments to measure knowledge about cancer screening where the measurement properties were sufficiently evaluated. There is a lack of focus on content validity and structural validity, and further validation of the instruments is needed. The results indicate a lack of shared understanding or agreement of what constitutes relevant knowledge about cancer screening.

Barriers and facilitators to implementing a multilevel, multicomponent intervention promoting colorectal cancer screening in health centers: a qualitative study of key informant perspectives

BACKGROUND

Colorectal cancer (CRC) continues to be a major cause of death in the U.S. despite the availability of effective screening tools. U.S. Latinos have lower rates of CRC screening and higher rates of death due to colorectal disease compared to non-Hispanic whites. Federally Qualified Health Centers (FQHCs) serve medically underserved populations, including many Latino patients. Given the low CRC screening rates, identifying culturally sensitive and cost-effective methods of promoting screening is a priority for many FQHCs.

METHODS

We interviewed FQHC leaders and providers using the Consolidated Framework for Implementation Research (CFIR) to identify barriers and facilitators to implementation of a multilevel, multicomponent (ML-MC) CRC screening intervention (i.e., promotor navigation and group-based education) in FQHCs. A rapid qualitative analysis approach was used to identify themes organized according to the following CFIR constructs: intervention characteristics, outer and inner settings, and characteristics of the individual.

RESULTS

We completed interviews with 13 healthcare professionals in leadership positions at six FQHCs. The participating FQHCs perceived the ML-MC screening CRC program as feasible and expressed interest in implementing the program at their sites. Facilitators included financial incentives for increasing screening rates, the need for patient education programming, and involving promotores to support the work of clinical teams. Barriers included concerns about available resources to implement new programs, lack of federal reimbursement for health education, competing priorities of other health concerns, and the need for more resources for confirmatory screening and treatment following a positive screen.

CONCLUSIONS

FQHCs provide essential primary care to millions of underserved patients in the U.S. and have the ability and motivation to provide screenings for colorectal cancer. Partnering with an academic institution to deliver a group-based, promotor-led CRC screening intervention for patients not up to date with screening could help increase screening rates. By identifying the specific barriers and facilitators to implementing CRC intervention, findings suggest that group-based, promotor-led interventions are a promising approach.

Knowledge, attitudes, practice and related factors of oral cancer prevention among public health nurses in Taiwan

OBJECTIVES

Public health nurses (PHNs) in Taiwan act as individual/family-based primary care providers and as population-based community care providers. A little information is currently available on the ability of PHNs to prevent oral cancer. We surveyed knowledge, attitudes and behaviour of oral cancer prevention among PHNs.

METHODS

This study recruited 400 PHNs through the Taiwan Public Health Center. A structured electronic questionnaire was used to collect PHNs' demographics and scale scores for oral cancer knowledge, attitudes and preventive behaviour.

RESULTS

Providing PHNs with oral cancer prevention education, having the supervisor's support for preventive work and receiving in-service education would improve PHNs' knowledge, attitude and behaviour for oral cancer prevention. Attitude, oral cancer-related courses arranged by current employer (major factor), supervisor's support for work and having responsibility for oral cancer prevention were associated with the oral cancer preventive behaviour of PHNs, and explain 41.1% of total variance.

CONCLUSIONS

We established a linear regression model for understanding the role of PHNs in the practice of preventing oral cancer. It may be useful for the government in improving school-based and in-service oral cancer prevention education programmes for PHNs as well as developing programmes for increasing public awareness and education of oral cancer prevention.
