Internet-delivered Cognitive Behavioral Therapy for insomnia in youth with autism spectrum disorder: A pilot study

Sleep quality relates to language impairment in children with autism spectrum disorder without intellectual disability

OBJECTIVES

This study aimed to identify sleep quality profiles of children with autism spectrum disorder (ASD), to compare these profiles with those of typically developing (TD) children, and to verify whether there are differences between them in terms of language skills.

METHODS

We evaluated the sleep quality and language skills of 47 children with ASD without intellectual disability (ID) and 32 children with TD. Using a hierarchical cluster analysis, we identified two sleep quality ASD profiles (poor and good). We then performed a series of MANCOVAs and ANOVAs to compare the sleep quality and language skills of the two ASD clusters and the TD group.

RESULTS

A main group effect (TD, "poor" cluster, and "good" cluster) was found in the total sleep quality and all its dimensions. Significant differences were revealed between the "good" and "poor" clusters in the total structural language score (F1,46 = 10.75, p < 0.001) and three of its subscales (speech: F1,46 = 9.19, p < 0.001; syntax, F1,46 = 8.61, p = 0.001; coherence: F1,46 = 11.36, p < 0.001); the total pragmatic language score (F1,46 = 7.00, p = 0.001) and three of its subscales (inappropriate initiation: F1,46 = 8.02, p = 0.001; use of context: F1,46 = 8.07, p = 0.001; nonverbal communication: F1,46 = 7.35, p = 0.001); and the social relations score (F1,46 = 9.97, p = 0.003).

CONCLUSIONS

Sleep quality in children with ASD (especially a subgroup) is worse than in children with TD. There is an association between sleep quality and language skills, both at the pragmatic and structural levels.

An internet-based behavioral intervention for adults with autism spectrum disorder - A randomized controlled trial and feasibility study

Background

The increased prevalence of Autism Spectrum Disorder (ASD) diagnoses in combination with psychiatric comorbidity, has led to an increased need for effective interventions. The evidence for internet-based interventions for several mental health problems is established but has not been evaluated for adults with ASD.

Objective

The aim of this randomized controlled trial is to evaluate the feasibility and effects of an internet-based intervention targeting quality of life and psychiatric symptoms (depression and anxiety) in adults with ASD.

Methods

84 participants were randomly allocated to intervention (n = 42) or control (n = 42). The 18-week internet-based intervention covered a range of themes related to difficulties common in ASD, and exercises based on cognitive behavioral strategies. Participants were provided with individual feedback following each module and were invited to regular chat sessions with peer participants. The primary outcomes were subjective quality of life and sense of coherence, and secondary outcomes were symptoms of depression and anxiety. All outcomes were measured at five occasions and analysed with linear mixed effect models. Participant satisfaction and adherence was also analysed.

Results

Participant satisfaction and adherence was satisfactory but no significant interaction between group and time was found for any outcome measure. Autistic traits were negatively related to quality of life and sense of coherence and positively related to anxiety and depressive symptoms.

Conclusions

This internet-based intervention showed feasibility regarding adherence and participant satisfaction. However, no significant effects on quality of life, sense of coherence or psychiatric symptoms were found, likely due to limitations in the design and methodology of this specific trial in combination to the heterogeneity of the group. Individuals with ASD may require interventions that are flexible and individually tailored in regard to both format, content and therapeutic support. The current trial provides useful information and suggestions for the future research on internet-based interventions for ASD.
