Abstract

Background & aims: The development of communicative competence requires both language and social skills. The ability to repair following a communication breakdown is critical for continued conversational interchange and to ensure comprehension of bids for communication. Repair demonstrates adequate language and social skills. Children with Fragile X Syndrome (FXS) have difficulty with language development and social skills, which may result in delays or deficits in repair. Repair may be additionally impaired in children with FXS and co-morbid autism. This study examined the development of repair in children with FXS from toddlerhood into middle childhood.

Methods: Fifty-five children with FXS and their biological mothers participated. Data were collected during in-home visits approximately every 18 months. Videotaped mother-child interactions were collected, as well as standardized assessments of language, social skills, and autism symptomology.

Results: Children with FXS acquired the ability to repair at 90% mastery by three-and-a-half years of age. Multilevel logistic regressions predicting probability of repair indicated marginally significant effects of mean length of utterance and number of different words, and significant effects of global social skills and autism symptomology. Effect sizes were small to moderate.

Conclusions: Ability to repair was measured in a naturalistic setting, which allowed children with FXS to utilize repairs in their daily interactions. Although children with FXS may have delayed development of repair relative to typically developing expectations, in general they nonetheless catch up and demonstrate a robust ability to repair by three-and-a-half years of age. However, this study provides evidence that individual differences in language and social skills may influence ability to repair in children with FXS. Finally, the relationship between autism symptoms and repair remains unclear, necessitating further exploration.

Implications: Given the noted delay in repair in young children with FXS, clinicians working with this population should target development of this skill as early as possible to maximize successful social interactions. This may be particularly necessary for children with FXS and co-morbid autism.

脆性X综合征儿童沟通修复的发展轨迹。
背景与目的:交际能力的发展既需要语言能力,也需要社交能力。沟通中断后的修复能力对于持续的对话交流和确保理解沟通请求至关重要。修显示出足够的语言和社交技能。患有脆性X染色体综合征(FXS)的儿童在语言发展和社交技能方面存在困难,这可能导致修复的延迟或缺陷。在患有FXS和共病自闭症的儿童中,修复功能可能会进一步受损。本研究考察了FXS患儿从幼儿期到儿童中期的修复发育情况。方法:55例FXS患儿及其生母参与。大约每18个月在家访期间收集数据。收集了母子互动的录像,以及对语言、社交技能和自闭症症状的标准化评估。结果:FXS患儿在3岁半时获得了90%的修复能力。预测修复概率的多水平逻辑回归表明,平均话语长度和不同单词数对修复概率有显著影响,整体社交技能和自闭症症状有显著影响。效应量从小到中等。结论:修复能力是在自然环境中测量的,允许FXS儿童在日常互动中利用修复。尽管与正常发育的预期相比,患有FXS的儿童可能会延迟修复能力的发展,但总的来说,他们在三岁半的时候就会赶上并表现出强大的修复能力。然而,本研究提供的证据表明,语言和社交技能的个体差异可能会影响FXS儿童的修复能力。最后,自闭症症状与修复之间的关系尚不清楚,需要进一步探索。意义:考虑到FXS患儿明显的修复延迟,临床医生应尽早培养这一技能,以最大限度地提高成功的社会互动。这对于患有FXS和共病自闭症的儿童尤其必要。
