“…There were several studies that pointed out within-study discrepancies between different types of measurements of hearing. For instance, self-reported or observer-based hearing impairment was associated with an increased psychosis risk but objective audiometry-based hearing impairment was not (Prager and Jeste, 1993;Stein and Thienhaus, 1993;van der Werf et al, 2007;Viertiö et al, 2014). Forty-nine studies were eligible for meta-analysis.…”

“…The study by Stefanis et al showed a nonsignificant association between the presence of proxy-reported hearing impairment at age 7 and subsequent psychotic symptoms at age 19 (Stefanis et al, 2006). Van der Werf et al (2007) reported no significant effect between audiometry-based presence of impaired hearing at baseline on the presence of psychotic symptoms three years later. However, in a similar community cohort, the same research group found a significant positive association between hearing impairment (as measured by tone audiometry) and the presence of psychotic symptoms six to twelve years later (van der Werf et al, 2010).…”

In this case, the effect of hearing impairment on psychosis is not explained by a direct causal mechanism between hearing impairment and psychosis, but rather through an indirect and independent connection based on a common denominator.…”

“…The PSYC and PAR scales have been used previously for assessing psychotic experiences in a general population sample (van der Werf et al, 2007) and as predictor of subsequent psychotic states (Wilson et al, 1985). The SCL-90-R is described as standard measure for a susceptibility to psychosis (Henquet et al, 2008).…”
Background: Early detection of psychosis is an important issue in current research. Early intervention helps to improve the outcome of the disorder. Therefore, a comprehensive examination in large populations, necessary as it might be, is economically almost not feasible. A screening via self-report is more practicable as it helps focus on individuals with high symptom loads. Results: Both groups (cases and non-cases) showed significant differences in their mean scores on SPro and ESI, although only the SPro had satisfactory effect sizes. In hierarchic logistic regression models the SPro turned out to be highly predictive for caseness while ESI scales were not significant. A cut-off score of ≥2 on the Spro subscale for psychotic risk (SPro-Psy-Risk) was found to identify caseness best with a sensitivity of 74% and a specificity of 61%.
Conclusion:The SPro has proven to be a valid and very economic screening tool for general and prodromal pathology in large populations.
Objective:To determine if hearing loss is associated with increased risk of incident psychosis in later life.Methods: Longitudinal cohort study of a community-representative sample of 38 173 men aged 65 to 85 years at the start of the follow-up period of 18 years.We used the Western Australian Data Linkage System to ascertain the presence of hearing loss and of psychotic disorders according to the International Classification of Diseases (ICD) (versions 8, 9, and 10). We also collected information on concurrent morbidities: cancer and diseases of the cardiovascular, respiratory, digestive, and renal systems.
Results:One thousand four hundred forty-two (3.8%) and 464 (1.2%) men had a recorded diagnosis of hearing loss and psychosis at the start of follow-up. After excluding the 464 participants with prevalent psychosis, 37 709 men were available for the longitudinal study, and of these, 252 (0.7%) developed a psychotic disorder.Competing risk regression showed that hearing loss was associated incident psychosis (subhazard ratio = 2.03, 95% CI, 1.24-3.32; after statistical adjustment for age and concurrent morbidities).
Conclusions:Hearing loss is associated with double the risk of incident psychosis in older men. Available evidence suggests that this link could be causal, although conclusive evidence is still missing from randomized controlled trials designed to test the effect of correction of hearing loss on the prevalence and incidence of psychosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
