Background: Autistic children without intellectual disability will likely experience higher level language and communication difficulties. These may appear subtle, in that they are not immediately evident to those who do not know the child well and may not manifest in all environments. Because of this, the impact of such difficulties may be underestimated. This phenomenon has similarly attracted little research attention, meaning the extent to which subtle language and communication difficulties contribute to the needs of autistic individuals without intellectual disability may be underspecified in clinical services. Aims: To offer a detailed exploration of how relatively subtle language and communication difficulties impact on autistic children without intellectual disability and what strategies parents recognize can mediate those negative effects. Methods & Procedures: Twelve parents of autistic children from the target group (aged 8–14 years, attending mainstream school) were interviewed about how subtle language and communication difficulties impact their autistic child. Rich accounts were derived then analysed using thematic analysis. Eight of the children discussed had previously been interviewed independently in a parallel study. Comparisons are discussed in this paper. Outcomes & Results: Parents reported heterogeneous but pervasive higher level language and communication difficulties which universally impacted key areas of the children's function: peer relationships, developing independence and performance in education. Communication difficulties were also universally associated with negative emotional responses, social withdrawal and/or negative self‐perceptions. While parents identified a range of ad hoc strategies and naturally occurring opportunities that improved outcomes, there was little mention of the means to address primary language and communication difficulties. The current study showed a number of parallels with child accounts, demonstrating the benefits of collecting data from both sources in clinical and research investigations. However, parents were more concerned about longer term implications of language and communication difficulties and highlighted their impact on the child developing functional independence. Conclusions & Implications: Subtle language and communication difficulties, typically identified in this higher ability autistic group, can impact significantly on key areas of childhood function. Support strategies seem to be parent generated and inconsistently applied across individuals, without the benefit of coherent specialist services. Dedicated provision and resources targeting areas of functional need may be beneficial to the group. In addition, the commonly reported association between subtle language and communication difficulties and emotional well‐being indicates the need for greater exploration using empirical methods, and joined‐up clinical working between speech and language therapy and mental health services. What this paper adds: What is already known on the subject: There is now a wide understanding of how language and communication difficulties can impact the individual. However, where those difficulties are relatively subtle, for example, in children without intellectual disability and where difficulties are not immediately evident, less is known. Research has often speculated on how identified differences in higher level structural language and pragmatic difficulties might impact on the function of autistic children. However, to date dedicated exploration of this phenomenon is limited. The current author group explored first‐hand accounts of children. Corroborative evidence from parents of the same children would add further weight to understanding this phenomenon. What this paper adds to the existing knowledge: This study provides a detailed exploration of parents' perspective relating to the impact of language and communication difficulties on autistic children without intellectual disability. It provides corroborative detail that support child accounts of the same phenomenon, indicating the impact on peer relationships, school outcomes and emotional well‐being. Parents also report functional concerns around the child's ability to develop independence and this paper demonstrates how parents and children might deviate in their accounts, with parents reporting increased concerns around the longer term implications of early language and communication difficulties. What are the potential or actual clinical implications of this work?: Relatively subtle language and communication difficulties can have a significant impact on the lives of autistic children without intellectual disability. Greater service provision for this group is therefore indicated. Interventions could focus on areas of functional concern where language is implicated, for example, peer relationships, developing independence and school success. Additionally, the relationship between language and emotional well‐being points to further integration between speech and language therapy and mental health services. Differences found between parental and child reports highlight the need to collect data from both parties during clinical investigations. Parental strategies may offer benefits for the wider population. [ABSTRACT FROM AUTHOR]
