Standardization of Korean Version of Frenchay Aphasia Screening Test in Normal Adults

Objective: To develop Korean version of Frenchay Aphasia Screening Test (K-FAST) and to standardize K-FAST in normal adult population in Korea. Method: The 'river scene' of stimulus set in original version of FAST was adapted for K-FAST. English version of the test instructions and scoring methods were translated into Korean and reverse-translation was performed by English-Korean bilinguals. The test structures and language domains (comprehension, expression, reading, and writing) were unchanged and possible maximum score was 30 points. We standardized K-FAST in 240 normal adult populations (male 102, female 138) whose ages were above 44. Basic personal information was collected through an interview and we performed Edinburgh handedness inventory (EHI), K-MMSE and K-FAST. Subjects who had history of brain disease, cognitive communicative disorders, or K-MMSE scores less than 2 percentile of same age group were excluded. K-FAST scores were analyzed according to the age and education groups. Results: Mean EHI K-MMSE, and K-FAST scores in total subjects were 9.4 +/- 1.2, 25.9 +/- 2.8, 25.4 +/- 3.3 points, respectively. Post-hoc analysis of K-FAST scores according to age groups classified into 3 age groups, 45 similar to 64, 65 similar to 74, and >= 74 years and education groups into 0, 1 similar to 9, >= 10 years of total education. K-FAST scores decreased significantly as increase of age (r= -0.441, p=0.000) and decrease of total years of education (r=0.580, r=0.000). Conclusion: Newly adapted K-FAST can be used for screening of aphasia in Korea and the standardized data according to age and education levels may provide useful reference values for interpretation of the results of K-FAST.
