Cochlear Implantation and Social Outcomes

2026年6月17日 更新者：Janet Choi、University of Southern California

The goal of this clinical trial is to learn if hearing devices, like cochlear implants, affect social and cognitive function of older adults. The main questions the researchers want to answer are:

  • How social are older adults with hearing loss before and after using hearing devices?
  • How well do older adults with hearing loss think before and after using hearing devices?
  • For older adults who have hearing loss and use hearing devices, do changes in social interaction explain changes in how well they think (cognitive function)?
  • Do brainwaves (EEGs) in older adults with hearing loss change after using hearing devices?
  • Are there differences in how social older adults with hearing loss are compared to older adults without hearing loss?

What Participants Will Do:

  • Participants will take questionnaires for around 60 minutes. Questionnaires will ask participants about their background, health, hearing, and how social they are. Another set of questionnaires will check their thinking ability or cognition.
  • Participants will wear an audio sensor (TILES Audio Recorder on Jelly Mobile phone) for 2 weeks. The sensor will collect and store information about a participant's voice during conversations. Once the device has information about a participant's voice such as pitch and tone it will store this information and delete the audio recording. Words spoken during conversations will be deleted.
  • (Optional) Participants can choose to participate in a 45-60-minute EEG (electroencephalogram) recording session. Participants will have sensors placed on top of their heads. Sensors will record the participants' brainwaves. Sounds will be played to see how participants' brainwaves change when they hear sounds. Eligible participants will be invited to participate in 4-month follow-up study.

主要な結果の測定

結果測定
メジャーの説明
時間枠
Audio sensor- speech arousal
時間枠：Baseline, optional 4-month follow-up
The audio sensor employs deep-learning-based multimodal speech pattern modeling of participants' own voice activities to extract speech arousal and speech activities. Speech arousal measures include the percentage of strong arousals, serving as a proxy of enhanced engagement in conversations.
Baseline, optional 4-month follow-up
Audio sensor- speech activity
時間枠：Baseline, optional 4-month follow-up
The audio sensor employs deep-learning-based multimodal speech pattern modeling of participants' own voice activities to extract speech arousal and speech activities. Speech activity measures include the intersession time (the interval between speech sessions, representing the frequency of conversation engagement).
Baseline, optional 4-month follow-up

メジャーの説明
時間枠
UCLA Loneliness Scale
時間枠：Baseline, optional 4 months follow-up
The UCLA Loneliness Scale is a 20-item self-report measure assessing subjective feelings of loneliness and social isolation. Total scores range from 20 to 80, with higher scores indicating greater loneliness and worse outcomes. Minimum score: 20; maximum score: 80. Higher scores represent worse outcomes.
Baseline, optional 4 months follow-up
Lubben Social Network Scale (LSNS-6)
時間枠：Baseline, optional 4 months follow-up
The Lubben Social Network Scale (LSNS-6) is a 6-item self-report measure assessing social engagement and perceived social support from family and friends. Total scores range from 0 to 30, with higher scores indicating larger and more supportive social networks (better outcomes). Minimum score: 0; maximum score: 30. Higher scores represent better outcomes.
Baseline, optional 4 months follow-up
Hearing Handicap Inventory for the Elderly - Screening Version (HHIE-S)
時間枠：Baseline, optional 4 months follow-up
The HHIE-S is a 10-item self-report questionnaire assessing the emotional and social/situational effects of hearing loss in older adults. Total scores range from 0 to 40, with higher scores indicating greater perceived hearing handicap and worse hearing-related quality of life. Minimum score: 0; maximum score: 40. Higher scores represent worse outcomes.
Baseline, optional 4 months follow-up
Generalized Anxiety Disorder 7-item (GAD-7) Scale
時間枠：Baseline, optional 4 months follow-up
The GAD-7 is a 7-item self-report questionnaire assessing the severity of generalized anxiety symptoms over the past two weeks. Total scores range from 0 to 21, with higher scores indicating greater anxiety severity and worse outcomes. Minimum score: 0; maximum score: 21. Higher scores represent worse outcomes.
