Analysis of Performance on Cognitive Test Measures Before, During, and After 6 Months of Hearing Aid Use: A Single-Subject Experimental Design

Purpose

The present study examined the effect of hearing aid use on cognitive test performance using a single-subject treatment design.

Method

Six participants 54 to 64 years old with sensorineural hearing loss were fitted with hearing aids. Participants used the hearing aids for approximately 8 hr each day for the duration of the study. A battery of cognitive tests was administered to participants during baseline (pre–hearing aid fitting), treatment (hearing aid use), and withdrawal (post–hearing aid use) study phases over a period of 6 months of hearing aid use.

Results

All participants showed significant improvements in performance on the cognitive test measures with hearing aid use. The most significant treatment effects were evidenced at 2 to 4 weeks of hearing aid use on the Listening Span Test and an auditory selective attention task. In many cases, cognitive performance scores returned to baseline levels after the participant stopped using the hearing aids.

Conclusion

The findings from this study are consistent with the hypothesis that hearing aid use may improve cognitive performance by improving audibility and decreasing the cognitive load of the listening task.

Revised Conceptual Framework of Parent-to-Parent Support for Parents of Children Who Are Deaf or Hard of Hearing: A Modified Delphi Study

Background

A scoping review of the literature was conducted, resulting in the development of a conceptual framework of parent-to-parent support for parents with children who are Deaf or hard of hearing. This is the 2nd stage of a dual-stage scoping review.

Purpose

This study sought stakeholder opinion and feedback with an aim to achieve consensus on the constructs, components, and design of the initial conceptual framework.

Research Design

A modified electronic Delphi study was completed with 21 handpicked experts from 7 countries who have experience in provision, research, or experience in the area of parent-to-parent support. Participants completed an online questionnaire using an 11-point Likert scale (strongly disagree to strongly agree) and open-ended questions to answer various questions related to the descriptor terms, definitions, constructs, components, and overall design of the framework.

Results

Participant responses led to the revision of the original conceptual framework.

Conclusion

The findings from this dual-stage scoping review and electronic Delphi study provide a conceptual framework that defines the vital contribution of parents in Early Hearing Detection and Intervention programs that will be a useful addition to these programs.

Prevalence and Nature of Hearing Loss in 22q11.2 Deletion Syndrome

Purpose

The purpose of this study was to clarify the prevalence, type, severity, and age-dependency of hearing loss in 22q11.2 deletion syndrome.

Method

Extensive audiological measurements were conducted in 40 persons with proven 22q11.2 deletion (aged 6–36 years). Besides air and bone conduction thresholds in the frequency range between 0.125 and 8.000 kHz, high-frequency thresholds up to 16.000 kHz were determined and tympanometry, acoustic reflex (AR) measurement, and distortion product otoacoustic emission (DPOAE) testing were performed.

Results

Hearing loss was identified in 59% of the tested ears and was mainly conductive in nature. In addition, a high-frequency sensorineural hearing loss with down-sloping curve was found in the majority of patients. Aberrant tympanometric results were recorded in 39% of the ears. In 85% of ears with a Type A or C tympanometric peak, ARs were absent. A DPOAE response in at least 6 frequencies was present in only 23% of the ears with a hearing threshold ≤30 dB HL. In patients above 14 years of age, there was a significantly lower percentage of measurable DPOAEs.

Conclusion

Hearing loss in 22q11.2 deletion syndrome is highly prevalent and both conductive and high-frequency sensorineural in nature. The age-dependent absence of DPOAEs in 22q11.2 deletion syndrome suggests cochlear damage underlying the high-frequency hearing loss.
