429: Validating the EAGL genetic literacy measure

Barna LS et al., Human Genetics and Genomics Advances - We summarize a psychometric validation of the EAGL measure using US adult online samples. The study produced a validated 17-item EAGL-short that captures three core genetic literacy constructs and can be used to assess and target genetic communication and education. Key terms: genetic literacy, EAGL, psychometrics, knowledge comprehension, autism. Study Highlights:The authors administered the EAGL across three online US samples (combined N ≈ 2,708) and used exploratory and confirmatory factor analyses to refine the instrument. The final EAGL-short contains 17 items loading on three factors: subjective knowledge, knowledge comprehension, and conceptual (objective) knowledge, with CFA fit indices showing excellent model fit (CFI = 0.996, RMSEA = 0.031, SRMR = 0.080). Regression analyses found numeracy to be the strongest predictor across subscales, a personal connection to autism raised subjective familiarity but not comprehension or conceptual knowledge, and metropolitan vs non-metropolitan status showed no main effects. An interaction between education and connection to autism was observed for knowledge comprehension, highlighting education as a moderator. Conclusion:The EAGL-short is a psychometrically sound, 17-item tool that measures subjective knowledge, knowledge comprehension, and conceptual genetic knowledge in US adults; it enables more precise assessment of genetic literacy and the design of targeted educational interventions, though further validation in other languages and settings is recommended.
