The aim of the present study was to investigate the validity of a community-based hearing test to detect conductive hearing loss in 3-year-old children. Sixty-five children had their hearing tested using standard audiological tests at the same time as they underwent their 3-year-old health checks. The checks were performed by health visitors at community health clinics, and included the McCormick Toy Test (MCTT) for hearing. Fourteen children failed both tests and none passed the MCTT and failed the standard tests, giving a sensitivity of 100%. Forty-eight children passed both tests and three children failed the MCTT but passed the standard tests, giving a specificity of 94%. Positive predictive value was 82%. The results from this sample indicate that the MCTT may be used as a valid test for conductive hearing loss for 3-year-old children in the community setting.
