Purpose The purpose of the present study is to evaluate the changes over time of the Spatial Hearing Questionnaire (SHQ; Tyler, Perreau, & Ji, 2009) and the Speech, Spatial and Qualities of Hearing Scale (SSQ; Gatehouse & Noble, 2004) in adults with simultaneous bilateral cochlear implants by collecting data for 2 years after implantation.

Method Nineteen postlingual subjects participated in this study. Average age at implant was 63 years. The subjects' data were included in this retrospective analysis only if they completed both questionnaires. We compared subjects' SSQ and SHQ scores to word recognition and sound localization performances.

Results The study showed SHQ and SSQ scores continuously improved up to 1 year postimplantation, with the most improvement occurring within the first 6 months of implantation. After 1 year, the scores reached a plateau. This is consistent with laboratory tests from the same 19 subjects, and they showed high correlations (p < .05). The present study also showed a high degree of correlation between SHQ and SSQ scores.

Conclusions Both the SSQ and SHQ scores improved up to 12 months postimplantation, with the most improvement during the first 6 months of implantation. Both were consistent with laboratory tests. There was a high degree of correlation between SHQ and SSQ scores.
