Can self assessment of communication predict hearing loss?

Abstract

A total of 120 subjects with hearing loss (75 men, 45 women), within the age range 18-70 years (mean, 38 years), and 15 normal subjects were administered a modified Hindi adaptation of the 'self assessment of communication' hearing loss inventory. The study aimed to determine whether there was any correlation between subjects' average pure tone thresholds and their inventory scores. Data was analysed using the Pearson coefficient of correlation and regression analysis. A negative correlation was obtained stating that the greater the hearing loss, the lower the inventory score. An equation could also be derived for the bilateral symmetrical sensorineural hearing loss group and the bilateral symmetrical conductive hearing loss group to enable calculation of patients' average hearing loss from their inventory scores, in the absence of an audiogram. This could aid rehabilitation in cases with either type of hearing loss (in which no medical intervention was required) when pure tone audiometry is not possible.
