A multilevel, low literacy dual language intervention to promote colorectal cancer screening in community clinics in Florida: A randomized controlled trial

Effect of a Theory-Based Narrative Video on Colorectal Cancer Screening Intention, Knowledge, and Psychosocial Variables Among a Predominantly Hispanic Population

Colorectal cancer (CRC) remains the third leading cause of cancer death in the USA. Latinx adults are overrepresented in late-stage CRC diagnosis as CRC screening utilization remains low among Latinx-identifying individuals. This study aims to evaluate the effect of a theory-based narrative video following a culturally appropriate storyline on CRC screening intention, knowledge, and psychosocial variables along the U.S.-Mexico border. We designed and analyzed a non-randomized pre-posttest evaluation of a narrative, culturally tailored video embedded within a community program. The study is set in the U.S.-Mexico border community. Outreach provided a link or QR code to access the survey. In all, 458 participants started the survey, and 304 completed the survey. Participants were recruited through flyers distributed throughout various community events by the program's community health workers and via social media. The intervention evaluated changes in participant's knowledge, perceived barriers, perceived susceptibility, self-efficacy, and perceived benefits and intention to screen. Participants were a mean age of 39 and identified mainly as female (72.7%) and Hispanic/Latinx (88.49%). After viewing the narrative video, participants had significantly improved perceived susceptibility, self-efficacy, and benefits, while perceived barriers and sense of fatalism significantly decreased. Paradoxically, this was associated with a significant decrease in knowledge scores. Results from this intervention suggest that a theory-based narrative video following a culturally appropriate storyline effectively improves psychosocial variables and intention to carry out CRC screening in a predominantly Hispanic border population.

Transcreation matters: A learner centric participatory approach for adapting cancer prevention messages for Latinos

BACKGROUND

Advancing health equity requires innovative patient education approaches for adapting English-language evidence-based interventions (EBIs) to resonate with multicultural, multilingual audiences.

OBJECTIVE

Examine the benefit, functionality, and practical considerations of transcreation (translation + cultural adaptation) as a critical and salient learner-centric process for developing a Spanish-language intervention (photonovella + video): Un examen sencillo para un colon saludable (A simple test for a healthy colon).

PATIENT/COMMUNITY INVOLVEMENT

We involved patients/community members in a participatory reflective process, from problem identification to intervention design, development, delivery, and impact measurement.

METHODS

A community-based participatory research (CBPR) approach involving formative research plus systematic iterative pretesting and learner verification checks augmented by a community advisory board guided the transcreation processes.

RESULTS

Data collected using a learner-centric approach effectively produced a new Spanish-language EBI and substantiated the value of co-learner/co-design methods. Learner-centric methods identified cultural nuances that were treated as knowledge and integrated into the intervention materials and study design. Pilot testing of the intervention among Latinos receiving care at community clinics demonstrated improved initial colorectal cancer screening uptake, awareness, and perceived susceptibility.

DISCUSSION

Inherent in the transcreation process was learner involvement that informed essential modification and adaptation of the materials. The transcreation methods led to the development of a culturally salient intervention that maintained theoretical integrity and message intent as well as behavioral activation. Findings have broad implications for the creation and transfer of EBIs to new audiences for greater adoption, engagement, and 'reach' of interventions.

PRACTICAL VALUE

Transcreation aligns with a growing paradigm shift in health communication science that brings to light the beneficial effect that construction and application of cultural knowledge has on patient education toward health equity.

Video Interventions for Reducing Health Inequity in Cancer Screening Programmes: a Systematic Review

BACKGROUND

Health equity can lead to disparities in cancer screening, treatment, and mortality. This systematic review aims to identify and describe interventions that used video or DVD formats to reduce health inequity in cancer screening and review the effectiveness of such interventions in increasing screening rates compared to usual care conditions.

METHODS

We searched PubMed, Web of Science, Embase, and Cochrane databases for randomized control trials (RCTs) published until 18/01/2023 that compared intervention versus usual care control groups, with the percentage of cancer screening uptake during follow-up as an outcome. The risk of Bias was assessed with the Cochrane Collaboration tool.

RESULTS

After screening 4201 abstracts, 192 full texts were assessed for eligibility and 18 were included that focused on colorectal (n = 9), cervical (n = 5), breast (n = 5), and prostate (n = 1) cancer screening. All were based in the USA except one and most focused on ethnicity/race, while some included low-income populations. Most of the video interventions used to increase cervical cancer screening reported positive results. Studies aimed at increasing mammography uptake were mostly effective only in specific groups of participants, such as low-income or less-educated African American women. Results for colorectal cancer screening were conflicting. Videos that were culturally tailored or used emotive format were generally more effective than information-only videos.

CONCLUSIONS

Video interventions to increase cancer screening among populations with low screening uptake show some positive effects, though results are mixed. Interventions that use individual and cultural tailoring of the educational material should be further developed and investigated outside of the USA.
