This study investigates the relationship between pre-linguistic social communication skills and age of cochlear implant for future language outcomes in a large sample of deaf children.
A retrospective cohort study of records from 75 children. Pre-implant data included Age at Implant, pre-linguistic communication (social, symbolic and speech) skills, and non-verbal ability. Receptive and expressive language development data at 1 year, 2 years and 4 years post implant were analysed to investigate the relationships between pre-implant factors and language outcomes, in particular pre-linguistic social communication skills in early and late implanted children.
Age at Implant was the strongest correlate of post implant expressive and receptive language outcomes. The sample was divided into early implanted (<18 month) and late implanted (>18 months) children. In the early implanted group, pre-linguistic social communication skills were the strongest pre-implant correlate of language outcomes four years post-implant. In the late implanted group, there were no significant pre-implant correlates of language outcomes.
Long term language outcomes after cochlear implantation are the product of a set of communicative, cognitive and environmental factors. Early pre-implant social communication skills are an important consideration for clinicians who guide parents as to likely long-term outcomes post cochlear implantation. Social communication skills are particularly important for children who receive implants before the age of 18 months.
本研究调查了大量失聪儿童样本中，语言前社交沟通技能与人工耳蜗植入年龄对未来语言发展结果的关系。
对75名儿童的记录进行回顾性队列研究。植入前的数据包括植入年龄、语言前沟通（社交、符号和言语）技能以及非语言能力。分析植入后1年、2年和4年的接受性和表达性语言发展数据，以研究植入前因素与语言发展结果之间的关系，特别是早期和晚期植入儿童的语言前社交沟通技能。
植入年龄是植入后表达性和接受性语言发展结果的最强相关因素。样本被分为早期植入（<18个月）和晚期植入（>18个月）儿童。在早期植入组中，语言前社交沟通技能是植入后四年语言发展结果的最强植入前相关因素。在晚期植入组中，没有显著的植入前语言发展结果相关因素。
人工耳蜗植入后的长期语言发展结果是一系列沟通、认知和环境因素的产物。对于指导家长了解人工耳蜗植入后可能的长期结果的临床医生来说，植入前早期的社交沟通技能是一个重要的考虑因素。社交沟通技能对18个月前接受植入的儿童尤为重要。
