Autism and Developmental Language Impairments最新文献

Objective: Raising a child with autism spectrum disorder (ASD) can have a significant impact on quality of life (QOL). This study was conducted to assess the QOL and coping strategies of parents of children with ASD in Oman.

Method: This descriptive cross-sectional study was conducted at Al-Masarra psychiatric hospital. Telephone interviews were conducted with the parents of all children diagnosed with ASD and attending Al-Masarra Hospital between January 2018 and October 2021. Data were collected using the Ways of Coping Checklist-Revised and World Health Organization Quality of Life Assessment-Brief.

Results: A total of 304 parents participated in the study (response rate: 100%), of which 59.5% were female. The mean age of the parents and children with ASD was 40.4 ± 6.9 and 8.4 ± 2.3 years, respectively. Most children with ASD were male (78.3%) and entirely dependent upon their parents (18.1%). Seeking social support was the most common coping strategy (75.53 ± 13.99), while escape avoidance was the least common (51.78 ± 8.04). Most parents (48.7%) rated their QOL as good to very good, with acceptable scores in the psychological (70.92 ± 11.22) and social (73.27 ± 11.46) domains, borderline in the physical health domain (63.51 ± 7.77), and poor in the environmental domain (58.31 ± 11.00).

Conclusions: Omani parents of children with ASD utilize various coping strategies, with coping skills considered a positive index for mental health in general. No significant differences were observed between Omani fathers and mothers in terms of QOL or coping strategies.

Aim: This study explores how bilingual parents of autistic children made language decisions for their families, how the event of the SARS-CoV-2 pandemic and subsequent lockdown impacted the communication environment of their households, and whether these experiences affected their language habits.

Method: Semi-structured interviews were conducted with five bilingual parents of autistic children who lived through lockdown in France. Data were analysed using interpretative phenomenological analysis. Demographic and background information was collected using an adapted version of the Questionnaire for Parents of Bilingual Children.

Results: Participants reported conflicting advice given by a range of practitioners. Parents expressed differing beliefs about the impact of language choices on their children. Parents described active engagement with their children's home-learning as generally positive. Parents identified an increase in children's exposure to their first language during the lockdown. Parents reported an increase in children's overall communication abilities.

Conclusion: Parents believed that their children's positive communication development during lockdown was related to increased exposure to their first language(s), and direct involvement in their children's learning programs.

Background and aims: The efficacy of parent-child reading for supporting language development has been well-established in the neurotypical (NT) literature. For children with autism spectrum disorder, (ASD) who may be at risk for delays in language development, prior research has shown promise for shared book-reading interventions. Yet there has been limited research on naturalistic parent-child reading with autistic children to date. The present study aimed to fill this missing link in the current literature.

Methods: Fifty-seven autistic toddlers participated at two developmental time points: Time 1 (Mage = 30.4 months) and Time 2 (Mage = 43.8 months). An NT control group (N = 31) was matched on age to a subset of the ASD group (N = 33). We assessed group differences in parent-child reading frequency between age-matched NT and autistic groups. Using a one-year follow-up design, we evaluated the relationship between parent-child reading and autistic children's language development.

Results: Cross-group comparisons revealed that parents of age-matched NT children reported significantly more frequent weekly parent-child reading than parents of autistic toddlers. After a one-year follow-up with the autistic group, within-group analyses revealed that greater frequency of parent-child reading (controlling for maternal education, books in the home, and autism symptom severity) was associated with larger growth in autistic toddlers' receptive and expressive language skills.

Conclusions and implications: These findings have important clinical implications as they emphasize the potential of parent-child reading for supporting autistic children's language development. Findings demonstrate that frequency of parent-child reading is associated with language development over one year. Findings also demonstrate that parents of autistic children engage in less frequent parent-child reading than parents of age-matched NT peers, suggesting these parents may face more barriers to implementing parent-child reading than parents of NT children.

Background and aims: Due to the COVID-19 pandemic, tele-health has gained popularity for both providing services and delivering assessments to children with disabilities. In this manuscript, we discuss the process of collecting standardized oral language, reading, and writing tele-assessment data with early elementary children with autism spectrum disorder (ASD) and offer preliminary findings related to child and parent engagement and technology issues.

Methods: The data presented are from pretest assessments during an efficacy study examining the electronic delivery of a listening comprehension intervention for children with ASD. Pretest sessions included a battery of standardized language, reading, and writing assessments, conducted over Zoom. The authors operationalized and developed a behavioral codebook of three overarching behavioral categories (parent involvement, child disengagement, and technology issues). Researchers coded videos offline to record frequencies of indicated behaviors across participants and assessment subtests.

Results: Involvement from parents accounted for the highest number of codes. Children showed some disengagement during assessment sessions. Technology issues were minimal. Behavioral categories appeared overall limited but varied across participants and assessments.

Conclusions: Parent involvement behaviors made up approximately two-thirds of the coded behaviors. Child disengagement behaviors made up approximately one-fourth of the coded behaviors, and these behaviors occurred more frequently across many different participants (with lower frequencies but greater coverage across children). Technology problems specific to responding to assessment items were relatively uncommon.

Implications: Clear guidelines including assessment preparation, modification of directions, and guidelines for parents who remain present are among the implications discussed. We also provide practical implications for continued successful adapted tele-assessments for children with ASD.

Background: The purpose of this study was to evaluate the feasibility of a personal narrative intervention based on neurocognitive principles and experientially based learning for improving the personal narrative language abilities of a school-age child with Down's syndrome.

Method: A single-case design using contemporary statistical techniques was employed to complete this study. The participant was 8 years 8 months at the time of the study and he participated in a 14-week personal narrative intervention. Personal narrative samples were collected at the beginning of each intervention session prior to instruction. Narrative samples were scored for narrative quality, language productivity, and lexical diversity.

Results: As a result of the intervention, the participant demonstrated moderate-significant increases in narrative abilities for narrative quality, language productivity, and lexical diversity.

Conclusions: The use of a personal narrative based on neurocognitive principles and experientially based learning may be feasible for improving the personal narrative language abilities of school-age children with Down's syndrome.

Background and aims: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by language impairment, and challenges with social interaction, communication, and repetitive behaviors. Although genetics are a primary cause of ASD, the exact genes and molecular mechanisms involved in its pathogenesis are not completely clear. The FOXP2 gene encodes a transcription factor that is known for its major role in language development and severe speech problems. The present study aimed to evaluate the role of FOXP2 in ASD etiology, executive functions, and brain activities.

Methods: In the present study, we recruited 450 children with ASD and 490 neurotypical control children. Three domains of executive functions (working memory, response inhibition, and vigilance) were assessed. In addition, five-minute eyes closed electroencephalography was obtained from some of the children with ASD and neurotypical children. DNA sequence and expression level of FOXP2 in blood samples of children with ASD and the control group were evaluated by using sequencing and Real-time PCR, respectively.

Results: The results showed no mutations but a significant down expression of FOXP2 genes in children with ASD vs. neurotypical children. Several cognitive and executive function deficiencies were detected in children with ASD. Low alpha and gamma bands in the frontal lobe and high theta bands in the occipital lobe were revealed in children with ASD. We also found several correlations between FOXP2 expression levels and clinical assessments.

Conclusions: Our finding revealed the down expression of FOXP2, which could be considered as a biomarker for ASD as well as cognitive and executive dysfunction. Based on brain mapping data, FOXP2 may be related to the theta wave abnormality of children with ASD. FOXP2 may be considered a target of novel treatment to improve memory and executive functions.

Implications: Our findings highlight the role of FOXP2 mRNA level in ASD etiology, executive functions, and brain wave frequencies.

Background and aim: Strategies to modify and adjust the educational setting in mainstream education for autistic students are under-researched. Hence, this review aims to identify qualitative research results of adaptation and modification strategies to support inclusive education for autistic students at school and classroom levels.

Method: In this systematic review, four databases were searched. Following the preferred PRISMA approach, 108 studies met the inclusion criteria, and study characteristics were reported. Synthesis of key findings from included studies was conducted to provide a more comprehensive and holistic understanding.

Main contribution: This article provides insights into a complex area via aggregating findings from qualitative research a comprehensive understanding of the phenomena is presented. The results of the qualitative analysis indicate a focus on teachers' attitudes and students' social skills in research. Only 16 studies were at the classroom level, 89 were at the school level, and three studies were not categorized at either classroom or school level. A research gap was identified regarding studies focusing on the perspectives of autistic students, environmental adaptations to meet the students' sensitivity difficulties, and how to enhance the students' inclusion regarding content taught and knowledge development from a didactic perspective.

Conclusions and implications: Professional development that includes autism-specific understanding and strategies for adjusting and modifying to accommodate autistic students is essential. This conclusion may direct school leaders when implementing professional development programs. A special didactical perspective is needed to support teachers' understanding of challenges in instruction that autistic students may encounter.

Existing measures of communication challenges in autism are based on diagnostic criteria and research/clinical observations of autistic people, rather than what autistic people themselves identify as difficulties. In this study, the Conversation Questionnaire (CQ) was developed based on community engagement with autistic people to identify what they find challenging about conversation. This new tool was then administered online to autistic, dyslexic and neurotypical people (N = 312) in a validation phase of the study. Item-response theory modelling indicated that a two-dimensional structure accounted for response patterns. These dimensions reflected difficulties knowing what to say (15 items) and engaging in behaviours possibly disruptive to neurotypical conversation (21 items). The dimensions showed good internal consistency and convergent and discriminant validity, and could distinguish between autistic and neurotypical people (d = 1.59 and d = 2.07 respectively). The CQ might help contribute to diagnostic assessment for autism in adults as part of a holistic assessment. The questionnaire might also be useful with other neurodiverse groups, and provide a tool for clinicians and researchers to identify individuals' strengths and difficulties in conversation (e.g., as part of interventions in speech and language therapy).

Background and aims: Previous studies suggest that syntactic development in children with intellectual disabilities (ID) is positively correlated with verbal short-term memory (VSTM). This study investigated the characteristics of syntactic development and their relationships of VSTM in children with ID based on type.

Methods: The participants were children with ID (N = 34), including 14 children with autism spectrum disorders (ASD), 20 with Down syndrome (DS), with chronological ages from 8 years 10 months to 18 years 4 months and nonverbal mental ages (MA) of over 4 years, and typically developing (TD) children (N = 21) with chronological ages from 5 years 0 months to 5 years 10 months. They were assessed using VSTM, syntactic comprehension, and expression tasks.

Results: The results showed that both the ASD and DS groups performed significantly lower on the syntactic comprehension task and the syntactic expression task than the TD group with the same nonverbal MA in the complex aspect of grammatical structure. In the VSTM task, the ASD group showed significantly lower performance in sentence and story repetition tasks than the TD group of the same nonverbal MA. The DS group showed significantly lower performance in forward digit span, and word, nonword, sentence, and story repetition tasks than the TD group of the same nonverbal MA.

Conclusions: These results suggest that children with ASD have difficulty in understanding and remembering linguistic information with complex semantic structures, and children with DS have a small capacity for VSTM, affecting their syntactic development.
