    The home literacy environment of school-age autistic children with high support needs.
    (John Wiley and Sons, 2024-08-01) Westerveld MF; Malone SA; Clendon S; Bowen R; Hayley G; Paynter J
    BACKGROUND: As a group, autistic children with high support needs (with adaptive functioning in the range of an intellectual disability) are at risk of significant literacy difficulties. We investigated the parent-reported home literacy environment of this group of children. METHOD: Sixty-two parents of autistic children (4.5 to 18.25 years) attending an autism-specific school completed a home literacy survey reporting on their child's: (1) alphabet knowledge, (2) interest in reading, (3) activities/interactions around books, (4) reading ability, and (5) writing ability. RESULTS: We found significant positive correlations between parent-reported child interest in reading and literacy-related interactions and skills, but not with child age. Children using spoken words to communicate obtained significantly greater scores on four home-literacy subscales, but not on reading interest. CONCLUSIONS: A better understanding of the home literacy activities of autistic children with high-support needs is needed to inform educational practices aimed at promoting literacy development in this vulnerable population.

    Using network analysis to identify factors influencing the heath-related quality of life of parents caring for an autistic child
    (Elsevier Ltd., 2024-09-01) Shepherd D; Buchwald K; Siegert RJ; Vignes M
    BACKGROUND: Raising an autistic child is associated with increased parenting stress relative to raising typically developing children. Increased parenting stress is associated with lower parent wellbeing, which in turn can negatively impact child wellbeing. AIMS: The current study sought to quantify parenting stress and parent health-related quality of life (HRQOL) in the autism context, and further understand the relationship between them by employing a relatively novel statistical method, Network Analysis. METHODS AND PROCEDURES: This cross-sectional study involved 476 parents of an autistic child. Parents completed an online survey requesting information on parent and child characteristics, parent's perceptions of their autistic child's symptoms and problem behaviours, and assessed their parenting stress and HRQOL. OUTCOMES AND RESULTS: Relative to normative data, parent HRQOL was significantly lower in terms of physical health and mental wellbeing. The structure extracted by the Network Analysis indicated that child age and externalising behaviours were the main contributors to parenting stress, and that externalising behaviours, ASD core behavioural symptoms, and parenting stress predicted HRQOL. CONCLUSIONS AND IMPLICATIONS: Parental responses to child-related factors likely determine parent HRQOL. Findings are discussed in relation to the transactional model, emphasising the importance of both parent and child wellbeing.

    Telehealth-delivered naturalistic developmental behavioural intervention with and without caregiver acceptance and commitment therapy for autistic children and their caregivers: protocol for a multi-arm parallel group randomised clinical trial.
    (BMJ Publishing Group Limited, 2023-05-30) McLay L; Emerson LM; Waddington H; van Deurs J; Hunter J; Blampied N; Hapuku A; Macfarlane S; Bowden N; van Noorden L; Rispoli M
    INTRODUCTION: Timely access to early support that optimises autistic children's development and their caregiver's mental health is critical. Naturalistic developmental behavioural interventions (NDBIs) and acceptance and commitment therapy (ACT) are evidence-based supports that can enhance child learning and behaviour, and adult well-being, respectively. The traditional face-to-face delivery of these approaches is resource intensive. Further, little is known about the benefit of parallel child-focused and caregiver-focused supports. The aims of this trial are to evaluate the effectiveness and social validity of telehealth-delivered, caregiver-implemented, child-focused NDBI and caregiver-focused ACT when delivered alone and in parallel, on autistic children's social communication and caregiver well-being. METHODS AND ANALYSIS: The study will use a randomised, single-blind clinical trial with three parallel arms: NDBI; ACT and ACT+NDBI. We will recruit a minimum of 78, 2-5-year-old autistic children and their families throughout Aotearoa New Zealand. Support will be delivered over 13 weeks using a combination of culturally enhanced web-based modules and online group coaching. Primary outcome variables include children's social communication/engagement with their caregiver as well as caregiver stress and will be evaluated using a repeated measures multivariate analysis of variance. Outcome variables are assessed at baseline (before randomisation), immediately postparticipation and at 3-month follow-up. ETHICS AND DISSEMINATION: The trial is approved by the Health and Disability Ethics Committee (2022 FULL 12058). The findings of this trial will be disseminated through peer-reviewed journals and national and international conference proceedings regardless of the magnitude/direction of effect. Additionally, data will be shared with stakeholder groups, service providers and health professionals. TRIAL REGISTRATION NUMBER: Australian New Zealand Clinical Trials Registry (ACTRN12622001134718).

    Protocol for the Gut Bugs in Autism Trial: a double-blind randomised placebo-controlled trial of faecal microbiome transfer for the treatment of gastrointestinal symptoms in autistic adolescents and adults.
    (BMJ Publishing Group, 2024-02-06) Tweedie-Cullen RY; Leong K; Wilson BC; Derraik JGB; Albert BB; Monk R; Vatanen T; Creagh C; Depczynski M; Edwards T; Beck K; Thabrew H; O'Sullivan JM; Cutfield WS
    INTRODUCTION: Autism (formally autism spectrum disorder) encompasses a group of complex neurodevelopmental conditions, characterised by differences in communication and social interactions. Co-occurring chronic gastrointestinal symptoms are common among autistic individuals and can adversely affect their quality of life. This study aims to evaluate the efficacy of oral encapsulated faecal microbiome transfer (FMT) in improving gastrointestinal symptoms and well-being among autistic adolescents and adults. METHODS AND ANALYSIS: This double-blind, randomised, placebo-controlled trial will recruit 100 autistic adolescents and adults aged 16-45 years, who have mild to severe gastrointestinal symptoms (Gastrointestinal Symptoms Rating Scale (GSRS) score ≥2.0). We will also recruit eight healthy donors aged 18-32 years, who will undergo extensive clinical screening. Recipients will be randomised 1:1 to receive FMT or placebo, stratified by biological sex. Capsules will be administered over two consecutive days following an overnight bowel cleanse with follow-up assessments at 6, 12 and 26 weeks post-treatment. The primary outcome is GSRS score at 6 weeks. Other assessments include anthropometry, body composition, hair cortisol concentration, gut microbiome profile, urine/plasma gut-derived metabolites, plasma markers of gut inflammation/permeability and questionnaires on general well-being, sleep quality, physical activity, food diversity and treatment tolerability. Adverse events will be recorded and reviewed by an independent data monitoring committee. ETHICS AND DISSEMINATION: Ethics approval for the study was granted by the Central Health and Disability Ethics Committee on 24 August 2021 (reference number: 21/CEN/211). Results will be published in peer-reviewed journals and presented to both scientific and consumer group audiences. TRIAL REGISTRATION NUMBER: ACTRN12622000015741.
