Randomized Trial of a Computerized Touch Screen Decision Aid to Increase Acceptance of Colonoscopy Screening in an African American Population with Limited Literacy

Abstract

The goal of this study was to assess the effectiveness of a touch screen decision aid to increase acceptance of colonoscopy screening among African American patients with low literacy, developed and tailored using perceptual mapping methods grounded in Illness Self-Regulation and Information-Communication Theories. The pilot randomized controlled trial investigated the effects of a theory-based intervention on patients’ acceptance of screening, including their perceptions of educational value, feelings about colonoscopy, likelihood to undergo screening, and decisional conflict about colonoscopy screening. Sixty-one African American patients with low literacy, aged 50–70 years, with no history of colonoscopy, were randomly assigned to receive a computerized touch screen decision aid (CDA; n = 33) or a literacy appropriate print tool (PT; n = 28) immediately before a primary care appointment in an urban, university-affiliated general internal medicine clinic. Patients rated the CDA significantly higher than the PT on all indicators of acceptance, including the helpfulness of the information for making a screening decision, and reported positive feelings about colonoscopy, greater likelihood to be screened, and lower decisional conflict. Results showed that a touch screen decision tool is acceptable to African American patients with low iteracy and, by increasing intent to screen, may increase rates of colonoscopy screening.

Attitudes Toward Genomic Testing and Prostate Cancer Research Among Black Men

“…There was lack of indebtedness that genomic tests would not reveal information about heritable traits, raising the question whether misunderstanding of the terms among those concerned with reveling information about heritable traits could influence their acceptance of such testing. Considering the extant-literature emphasis on patient education to improve health literacy 19,20 and the interest expressed by this study’s participants in becoming better educated about genomic testing, improvement of patient-centered education is essential. Decision aids have been shown to effectively provide concise education about complex medical issues, including PSA testing, 21,22 and could possibly be applied to genomic testing.…”

Using social marketing strategies to develop and pretest PrEP education materials for transgender women

“…Overall, these methods can help target messages to the specific needs of a population, as a commercial entity might market a product to a consumer. This is unique to the development of public health social marketing interventions and has been shown in other studies by the authors to be effective (Bass et al, 2013;Ruzek et al, 2016;Jessop et al, 2019).…”

A Subjective Culture Approach to Cancer Prevention: Rural Black and White Adults’ Perceptions of Using Virtual Health Assistants to Promote Colorectal Cancer Screening

“…This finding regarding trust is in line with previous research. Positive source attribution has also been demonstrated as being associated with increased intentions to seek additional cancer information, to share information, and to intend to screen for cancer -all important cognitive precursors to actual cancer screening (Ruzek et al, 2016). In fact, Nivens et al (2001) found that among a predominantly African American study population, receiving information from a trusted health source was more strongly associated with increased prostate screening than any other kind of predictor.…”
