Picture this: Evaluating the efficacy of genetic counseling visual aids

Visual aids have been validated as effective tools for educating patients in a variety of medical settings. However, research exploring the efficacy and potential benefit of genetic counseling visual aids is lacking. To begin to address this gap, this study assessed participant knowledge of genetic counseling concepts after viewing either visual or non-visual educational content. Participants were recruited from the general population using the crowdsourcing platform Mechanical Turk. Wilcoxon rank-sum tests were carried out to evaluate differences in knowledge survey scores between the visual and non-visual groups, and Poisson regression models were fitted to evaluate these differences across a variety of demographic backgrounds. The visual group had equal or higher scores than the non-visual group across all analyses. The difference in group scores was statistically significant for autosomal recessive inheritance knowledge scores (p < 0.05). In addition, this difference was approaching significance for higher-level knowledge scores (p = 0.05) and total knowledge scores in individuals who have not completed post-secondary education (p = 0.05). These results indicate that visual aids improve knowledge of specific genetic counseling concepts such as inheritance patterns; the education of which is often integral to genetic counseling. These results also indicate that visual aids may facilitate a deeper understanding of genetic counseling concepts and may be particularly valuable for individuals with lower educational backgrounds. Together, the results of this study support the inclusion of visual aids in genetic counseling education to help improve patient understanding and the accessibility of genetic healthcare information.
