“…This result is consistent with a finding that increased apprehension about developing breast cancer is a modest but reliable predictor of increased likelihood to get screened (Hay, McCaul, & Magnan, 2006). Guided by the EPPM, another study examined cognitive, affective, social, and behavioural predictors of intention to undergo colonoscopy screening in individuals with a family history of CRC (Boonyasiriwat et al, 2014a). Relatives of colorectal cancer cases eligible for colonoscopy screening completed a survey assessing constructs from several theoretical frameworks.…”

Background Ethnic minorities, especially African Americans and Latinos, bear a disproportionate burden of colorectal cancer (CRC) reflected in incidence, cancer stage and mortality statistics. In all ethnic groups first-degree relatives (FDRs) of CRC cases are at elevated disease risk. However, underutilization of CRC screening persists and is particularly evident among minority groups. This study tested a stepped intervention to increase CRC screening among an ethnically diverse sample of FDRs of CRC cases. Methods A statewide cancer registry was used to recruit CRC cases and through them their FDRs. Relatives not current on CRC screening were randomized to intervention or usual-care control arms. The stepped intervention consisted of ethnically-targeted and individually-tailored print materials followed by telephone counseling for those unscreened at 6 months. Results The sample (N=1280) consisted of 403 Latino, 284 African American, 242 Asian, and 351 White FDRs. Statistically significant effects were observed for the cumulative print+telephone intervention at 12-months (26% intervention vs.18% control) and the print intervention alone at 6 months (15% intervention vs. 10% control). The effect of the print alone versus the cumulative interventions was not significantly different. Stratified analyses indicated that the intervention was effective among Whites, Latinos, and Asians, but not among African-Americans. Conclusion Overall, the intervention was effective in increasing in screening rates. Oversampling racial/ethnic minorities allowed for examination of effects within subgroups, revealing no effect among African Americans. This finding illustrates the importance of including sufficient numbers of participants from diverse ethnic sub-groups in intervention research, to enable such stratified analyses.

“…One systematic review, 1 review article, and 10 original studies were identified for this question . A recent systematic review found that the most important predictors of screening adherence were having a physician recommendation (this increased the likelihood of screening 5‐ to 27‐fold) and having multiple affected family members (screening was 3.7 times more likely if more than 1 FDR was affected) .…”

Background Persons with a family history (FH) of colorectal cancer (CRC) or adenomas that are not due to known hereditary syndromes have increased risk for CRC. Understanding these risks, screening recommendations and screening behaviors can inform strategies to reduce CRC burden in these families. Methods A comprehensive review of literature published within the past 10 years was conducted to assess what is known about cancer risk, screening guidelines, adherence and barriers to screening and effective interventions in persons with FH of CRC, and to identify FH tools used to identify these individuals and inform care. Results Existing data show that having one affected first-degree relative (FDR) increases CRC risk by 2-fold, and risk increases with multiple affected FDRs and younger age at diagnosis. There was variability in screening recommendations across consensus guidelines. Screening adherence was <50% and lower in persons under age 50. Having a provider’s recommendation, multiple affected relatives and family encouragement facilitated screening; insufficient collection of FH, low knowledge of guidelines, and poor family communication were important barriers. Effective interventions incorporated strategies for overcoming barriers but these have not been tested broadly in clinical settings. Conclusions Four strategies for reducing CRC in persons with familial risk are suggested: 1) improve how we collect and utilize cancer FH, 2) establish consensus for screening guidelines by FH, 3) enhance provider-patient knowledge of guidelines and communication about CRC risk, 4) encourage survivors to promote screening within their families, and partner with existing screening programs to expand reach to high-risk groups.
