The effectiveness of real word satisfaction is very important for optimal hearing aid (HA) fitting, which can be assessed using self-report questionnaires. The Client Oriented Scale of Improvement (COSI) and Abbreviated Profile of Hearing Aid Benefit (APHAB) are useful tools for assessing the effectiveness of HA in achieving patient satisfaction.
Patients and methods
This study included 20 hearing-impaired adults. Their hearing thresholds ranged from moderate to moderately severe sensorineural hearing loss and had previous experience with HAs. Their ages ranged from 18 to 60 years, and the mean duration of HA experience was 3.85±5.02 years. Participants were examined in three scheduled sessions: unaided, aided National Acoustics Laboratories-Nonlinear 2 (NAL-NL2), and aided desired sensation level (DSL) v5. Each session was scheduled 2 months after the previous session. Patient satisfaction was assessed using the COSI and APHAB questionnaires for each HA fitting formulae.
Both formulae have improved patient’s five client needs of the COSI; however, NAL-NL2 had better final ability score compared with DSL v5. Using the APHAB questionnaire, both formulae have decreased the listening difficulty score significantly. Using APHAB questionnaire, NAL-NL2 showed significantly less listening difficulty compared with DSL v5 as regards difficulties in ease of communication, broadband noise, and reverberation. However, both formulae did not improve ‘aversiveness’ conditions.
Questionnaires are equally important to audiometric tests and should not be underestimated and hence should be relied upon it in HA-fitting verification.
