Abstract

Objective: To assess the relationship and agreement between mean total scores for the Speech Spatial Qualities of Hearing Scale (SSQ49) and the shorter SSQ12 to measure daily hearing function for a large group of auditory implant recipients.

Methods: Prospective, longitudinal self-assessment by 1013 implant recipients using the SSQ49 at preimplant and at annual post-implant intervals (one, two and three-years) via an international registry. Mean total scores were calculated for the SSQ49 and the extracted SSQ12 responses. Pearson correlation and Bland-Altman agreement were examined between the SSQ49, SSQ12 and transformed SSQ12 versions. Longitudinal mixed-effects models were used to compare changes over time.

Results: Very high correlation was shown between mean total scores for all versions while perfect agreement was not reached. Clinically acceptable agreement (<1.0 unit) between all versions was obtained with the transformed SSQ12 being least biased. All versions showed statistically significant improvement at one-year post-implant (>2.2 units; p < 0.001).

Conclusions: All scale-versions showed comparable sensitivity to changes in self-reported hearing function over time. TheSSQ12 may be considered as a potential time-efficient self-assessment of hearing function for implant recipients in routine practice. Further research may involve independent repeated administration of each scale version.
