Hearing impairment and psychosis revisited.
The previously reported but still poorly investigated link between deafness or hearing impairment (DHI) and the onset of positive psychotic experiences was investigated prospectively in a general population sample. Of the 109 DHI subjects at baseline, 11 (10.1%) displayed psychotic experiences at T(2) versus 137 (2.9%) of the non-DHI subjects (OR=3.8, 95% CI: 2.0, 7.2). This effect size was only slightly attenuated after adjustment for baseline psychotic experiences (OR=3.2, 95% CI: 1.6, 6.5) and after adjustment for T(0) psychotic experiences and a range of other confounders (OR=3.0, 95% CI: 1.4, 6.2) These results confirm previous findings of an association between hearing impairments and psychosis and show that this association can also be found prospectively in a nonclinical population.
