We validated a Korean version of the Broad Autism Phenotype Questionnaire (BAPQ) by investigating its factor structure with a nonclinical sample. Participants were 495 undergraduate students in Korea. The results show that the Korean version of the BAPQ (K-BAPQ) had adequate internal consistency (Cronbach’s α = .75–.89). Correlations between scores on the BAPQ and on the Autism-Spectrum Quotient were statistically significant and moderate-to-high in size. Confirmatory factor analysis did not show a satisfactory fit with the factor structure of the original BAPQ. Exploratory factor analysis demonstrated that a three-factor structure could be suitable in our sample, but the internal structure of the BAPQ still needs further examination. We recommend use of the total score of the K-BAPQ, as opposed to those of the subscales alone, and suggest that further research is needed to confirm the factor structure.
