Objective:To develop an appropriate mass screening system to evaluate hearing loss for primary school children,especially in rural areas.Methods:In Jiangsu Province,at a rural primary school-Longdu Primary School,317 of 479 rural students(from Grade 1 to Grade 6,over 50 students for each grade)were screened by,using the Chinese Hearing Questionnaire for School Children(CHQS).Two weeks later,they accepted transiently evoked otoacoustic emissions(TEOAEs)test.At the same time,all participants were given a ’gold standard’ audiological assessment that comprised of otoscopy,pure tone,and tympanometry.After eight weeks,103 out of the 317 students accepted the second TEOAEs and ’gold standard’ test to confirm the results.Results:There was no statistical difference in the results of two ’gold standard’ test(χ2 = 0.14,0.5 < P < 0.75).Compared with the ’gold standard’ results,the hit rate,sensitivity,specificity of the CHQS was 57% ± 2.78%,61% ± 10.18%,57% ± 2.89% respectively(α = 0.43,β = 0.39).Youden Index J,LR+,LR-,PV+ and PV-was 0.18 ± 0.11,1.42,0.68,0.10,0.95(Az < 0.54,EF = 0.75-0.95).While a higher system accuracy was obtained by TEOAEs[HR = 97 ± 0.71%,Sen = 69 ± 7.8%,Spe = 98 ± 0.52%(α = 0.02,β = 0.31),Youden Index J = 0.67 ± 0.08,LR+ = 34.5,LR-= 0.32,PV+ = 0.71,PV-= 0.99(Az = 0.85,EF = 0.97)].Conclusion:TEOAEs got a high efficiency and specificity values with reasonable sensitivity.However,CHQS needs substantial modifications to improve its sensitivity in evaluating hearing loss.
