The Effect of Listening Effort, Cognition and Anxiety-depression in Listening Satisfaction by Hearing Aid Users

Plain-language summary

Brief Summary Introduction: Listening can be effortful in situations that require the intensive use of cognitive processing resources especially for individuals with a hearing loss. Hearing-impaired listeners are under a greater degree of cognitive challenge during a hearing task, speech comprehension, memory, response in an auditory message. Listening effort is defined as 'the attention and cognitive resources required to understand speech'. Hearing ability is the strongest predictor of speech understanding accuracy, but cognitive factors, psychological state of the listener and stress also play a significant role. Although there is no gold-standard method for listening effort assessment. a wide range of techniques is used such as: a) self-report methods, b) behavioral measures, or c) physiological measures. Cognitive functioning refers to multiple mental abilities, including receiving visual and auditory message, decision making, processing information and memory skills. During the ageing process there is a decline in cognitive function. The most common tools to measure it are: a) Montreal Cognitive Assessment (MoCA) test b) Mini-Mental State Exam (MMSE), and c) το Mini Cog. Within the older adult population with hearing loss, prevalence estimates that up to 20% report a clinically relevant level of depression symptoms that would necessitate treatment. A cross-sectional association between hearing loss and depression among older adults has been consistently observed. A reduction in activities of daily living observed in older adults with hearing loss, suggesting that disengagement in activities post-hearing loss may contribute to depression. The satisfaction due to amplification for the hearing aid- user is effected by the changes in his everyday routine and also depend on the level of his cognitive function, motivation, psychological status and social environment. Purpose: The purpose of this study is to investigate the effect of listening effort, cognitive function, stress and depression on amplification satisfaction for adult hearing aid-users. Methods and materials: This is a prospective study including patients examined in the outpatient department of ENT clinic in General Hospital of Chania. Patients fulfilling the inclusion criteria will undergo: a) medical history record, b) ENT examination, c) pure tone audiogram and speech audiometry (with and without the hearing amplification) d) listening effort evaluation (with and without the hearing amplification) Self-report and behavioral methods will be used: Evaluation of subjective performance (Spatial Hearing Questionnaire (SHQ) Evaluation of time response in auditory message Evaluation of speech comprehension with background noise or a competitive speaker e) cognitive function evaluation by using the Greek version of Mini-Mental State Examination, f) evaluation of hearing-aid satisfaction, by using the Glasgow Hearing Aid Benefit Profile (GHABP), and International Outcome Inventory - Hearing Aid (IOI-HA), questionnaires and g) evaluation of stress level and depression by using BECK-II and STAI questionnaires. Results: The main outcome will be the assessment of listening effort, cognitive function, psychological status (stress/depression) effect on the level of satisfaction of hearing-aid users. Additional outcomes will be the assessment of the effect of cognitive decline in listening effort and the effect of psychological status on listening effort. Study findings will highlight the potential of changing the approach and management of the hearing aid-users in a way that hearing amplification will lead to satisfaction of their expectations
