Hearing Loss Clinical Trial
Official title:
Assessment of Listening, Speech, and Language Proficiency, and of Experienced Quality of Life in People Who Have Received Cochlear Implants as Children.
Treatment with cochlear implantation is now offered to proximately 95 % of children with deafness in Norway. More than 500 children have been operated at Oslo University Hospital. The study is a cross-sectional study aimed to investigate speech perception, language skills, quality of life in all childhood cochlear implant (CI) recipients in Norway from 1988-2012. Factors such as child characteristics, characteristics with the family, the cochlear implant, the rehabilitation situation, choice of communication mode, school and work situation are surveyed to see if these factors can be associated with variations in outcome. The study will include pre and post lingual deaf children and children with multiple disabilities. Participants are recruited and examined in conjunction with their annual CI control at the hospital. It will be conducted a series of tests determining listening, speech and language development, non-verbal intelligence. Questionnaires are used to collect background information and quality of life experience. The questionnaires include self-report forms for different age groups, and a parent report form. The patient will be tested for the most common genetic causes of deafness. Additional data will be collected from patient records and from local health register at Oslo University Hospital.
