Most health literacy assessments are time consuming and are administered verbally. Written self-administration of measures may facilitate more widespread assessment of health literacy. The aim of this study was to determine the inter-method reliability and concurrent validity of the written administration of the three subjective health literacy questions of the Short Literacy Survey (SLS). The Rapid Estimate of Adult Literacy in Medicine (REALM) and the shortened Test of Functional Health Literacy in Adults (S-TOFHLA) were the reference measures of health literacy. 299 participants (52±13 years old, 56% female, 67% white) completed the written and verbal administrations of the SLS June-December 2012. Inter-method reliability was demonstrated when: a) the written (median=14, IQR: 12–15) and verbal SLS (median=14, IQR:11–15) did not differ (Wilcoxon signed rank test, p=0.085); and b) written and verbal scores were highly correlated (Spearman’s rho=0.788, p<0.001). The written items were internally consistent (Cronbach’s alpha=0.733). The written total score successfully identified persons with ≤ 6th grade equivalent for literacy on the REALM (AUROC = 0.753) and inadequate literacy on the S-TOFHLA (AUROC = 0. 869). The written administration of the SLS is reliable, valid, and is effective in identifying persons with limited health literacy.
