The development and cross-validation of a self-report inventory to assess pure-tone threshold hearing sensitivity.

Previous attempts to assess hearing loss by means of self-report survey items have shown only low to moderate correlations with actual audiometric measures, probably because these attempts used items with high face validity rather than laboratory-tested validity. Beginning with a pool of 108 items used with 384 individuals, we developed a self-report inventory (see Appendix) suitable for group testing or survey administration, which appears to have high correlation with pure-tone hearing thresholds. The inventory was then cross-validated against laboratory audiometric measures in a separate sample of 422 subjects. The resulting 12-item Hearing Screening Inventory (HSI) was shown to be reliable with an internal consistency coefficient (alpha) of 0.89 and test-retest stability coefficient of 0.88. The correlation between pure-tone hearing thresholds in the better ear and the HSI scores for the combined samples was r = 0.81. The correct classification rate for the HSI was 92.1% for a low fence of 25-dB hearing level and 93.4% for a high fence of 55-dB hearing level. A conversion equation with estimated variability is also provided for point estimates of pure-tone hearing thresholds from the HSI scores. A copy of the inventory and scoring procedure is appended to this report.
