RESUMO
BACKGROUND: The UK National Health Service (NHS) Long Term Plan aims to reduce waiting times for childhood autism diagnostic assessment and improve parent and child satisfaction. This empirical research investigated current childhood diagnostic practice provision, and changes made by teams to address challenges faced. METHODS: Data were collected using an online semi-structured research questionnaire. UK childhood autism diagnostic assessment services (for children aged 1-18 years) were invited to participate through multidisciplinary clinical networks, special interest groups and professionals mailing lists. The study was on the National Institute for Health Research Clinical Research Network portfolio. RESULTS: 128 clinicians from diverse NHS services responded including: 10 (8%) integrated services, 46 (36%) Child and Adolescent Mental Health Services (CAMHS) and 72 (56%) paediatric services. A minority of services (23, 17.9%) reported always meeting the National Institute for Health and Care Excellence guidance for assessment. Referrals rose 115% between 2015 and 2019. Clinicians described increased child and family complexity compared with previously; children had more co-occurring physical, mental health and neurodevelopmental conditions and there were more frequent family health problems and safeguarding concerns. Most services (97, 75.8%) reported recent funding stayed constant/decreased. Incomplete multidisciplinary teams (MDTs) were frequently reported; a minority of services reported increased availability of professionals, and some experienced reductions in key professionals. Many teams were unable to undertake assessments or make recommendations for associated neurodevelopmental and co-existing conditions. Teams described improvement strategies implemented (eg, adapting professionals' roles, supporting parents). CONCLUSIONS: Most UK autism paediatric and CAMHS diagnostic teams experience significant challenges affecting the assessment of children with possible autism, and recommendations regarding treatment/intervention. Where CAMHS or paediatric services work in isolation, there are often competency gaps in MDTs and ability to deliver full neurodevelopmental and mental health assessments. Teams identified service improvement strategies; however, investment in MDT expertise is required to enable services to implement changes to meet the needs of children and families.

Adaptive functioning of autistic children is traditionally measured through informant-report, often from parents. Behaviour varies across settings though, and context-specific reports should be considered. Limited and inconsistent results show low parent-education professional concordance, but no research has yet explored item level response variation. We investigated Vineland Adaptive Behaviour Scales-II concordance using 233 lower ability autistic children from the PACT-G sample. Domain and item level agreement was low, but better on objectively measured behaviours. Higher child nonverbal ability improved concordance. Where disagreements occurred, education professionals identified emergent skills more and parents were more likely to rate present/absent. Parents and education professionals view the adaptive abilities of autistic children differently and both should be considered when developing personalised interventions and support.

BACKGROUND: Anxiety related to uncertainty is common in autism. Coping with Uncertainty in Everyday Situations (CUES©) is a parent-mediated group intervention aiming to increase autistic children's tolerance to uncertain situations. A pilot study was conducted to test its feasibility and acceptability. METHODS: Parents of 50 autistic children were randomised to receive CUES© or enhanced services as usual. RESULTS: All children met the clinical threshold for at least one anxiety disorder. Of the 26 participants randomised to CUES©, 72% attended 4-8 sessions. Parents and therapists reported they found CUES© useful and acceptable. CONCLUSIONS: Families were willing to be recruited and randomised, the format/content was feasible to deliver, and the outcome measures were acceptable. CUES© should be evaluated in a clinical and cost effectiveness randomised controlled trial.

BACKGROUND: Autistic children can have difficulty generalising treatment effects beyond the immediate treatment context. Paediatric Autism Communication Therapy (PACT) has been successful when delivered in the clinic. Here we tested the Paediatric Autism Communication Therapy-Generalised (PACT-G) intervention combined between home and education settings for its overall effect and mechanistic transmission of effect across contexts. METHODS: In this parallel, single-blind, randomised, controlled trial, we recruited autistic children aged 2-11 years in urban or semi-urban areas in Manchester, Newcastle, and London, England. Children needed to meet core autism criteria on Autism Diagnostic Observation Schedule-second edition (ADOS-2) and parent-rated Social Communication Questionnaire (SCQ-lifetime), and children older than 5 years were included if they had intentional communication but expressive language equivalent of age 4 years or younger. Eligible children were randomly assigned (1:1), using block randomisation (random block sizes of 2 and 4) and stratified for site, age (2-4 years vs 5-11 years), and gender, to either PACT-G plus treatment as usual or treatment as usual alone. Research assessors were masked to treatment allocation. The PACT-G intervention was delivered by a therapist in parallel to the child's parents at home and to learning-support assistants (LSA) at their place of education, using both in-person and remote sessions over a 6 month period, to optimise adult-child social interaction. Treatment as usual included any health support or intervention from education or local community services. The primary outcome was autism symptom severity using the ADOS-2, as measured by researchers, at 12 months versus baseline. Secondary outcomes were Brief Observation of Social Communication Change (BOSCC) and dyadic social interaction between child and adult across contexts, both at 12 months. Other secondary outcome measures were assessed using the following composites: language, anxiety, repetitive behaviour, adaptive behaviour, parental wellbeing, child health-related quality of life, and disruptive behaviour. Assessments were done at baseline, 7 months, and 12 months. We used an intention-to-treat (ITT) analysis of covariance for the efficacy outcome measures. Adverse events were assessed by researchers for all trial families at each contact and by therapists in the PACT-G group at each visit. This study is registered with the ISRCTN Registry, ISRCTN 25378536. FINDINGS: Between Jan 18, 2017, and April 19, 2018, 555 children were referred and 249 were eligible, agreed to participate, and were randomly assigned to either PACT-G (n=122) or treatment as usual (n=127). One child in the PACT-G group withdrew and requested their data be removed from the study, giving an ITT population of 248 children. 51 (21%) of 248 children were female, 197 (79%) were male, 149 (60%) were White, and the mean age was 4·0 years (SD 0·6). The groups were well balanced for demographic and clinical characteristics. In the PACT-G group, parents of children received a median of 10 (IQR 8-12) home sessions and LSAs received a median of 8 (IQR 5-10) education sessions over 6 months. We found no treatment effect on the ADOS-2 primary outcome compared with treatment as usual (effect size 0·04 [95% CI -0·19 to 0·26]; p=0·74), or researcher-assessed BOSCC (0·03 [-0·25 to 0·31]), language composite (-0·03 [-0·15 to 0·10]), repetitive behaviour composite (0·00 [-0·35 to 0·35]), adaptive behaviour composite (0·01 [-0·15 to 0·18]), or child wellbeing (0·09 [-0·15 to 0·34]). PACT-G treatment improved synchronous response in both parent (0·50 [0·36 to 0·65]) and LSA (0·33 [0·16 to 0·50]), mediating increased child communication with parent (0·26 [0·12 to 0·40]) and LSA (0·20 [0·06 to 0·34]). Child dyadic communication change mediated outcome symptom alteration on BOSCC at home (indirect effect -0·78 [SE 0·34; 95% CI -1·44 to -0·11]; p=0·022) although not in education (indirect effect -0·67 [SE 0·37; 95% CI -1·40 to 0·06]; p=0·073); such an effect was not seen on ADOS-2. Treatment with PACT-G also improved the parental wellbeing composite (0·44 [0·08 to 0·79]) and the child disruptive behaviour composite in home and education (0·29 [0·01 to 0·57]). Adverse events on child behaviour and wellbeing were recorded in 13 (10%) of 127 children in the treatment as usual group (of whom four [31%] were girls) and 11 (9%) of 122 in the PACT-G group (of whom three [33%] were girls). One serious adverse event on parental mental health was recorded in the PACT-G group and was possibly study related. INTERPRETATION: Although we found no effect on the primary outcome compared with treatment as usual, adaptation of the 12-month PACT intervention into briefer multicomponent delivery across home and education preserved the positive proximal outcomes, although smaller in effect size, and the original pattern of treatment mediation seen in clinic-delivered therapy, as well as improving parental wellbeing and child disruptive behaviours across home and school. Reasons for this reduced efficacy might be the reduced dose of each component, the effect of remote delivery, and the challenges of the delivery contexts. Caution is needed in assuming that changing delivery methods and context will preserve an original intervention efficacy for autistic children.

A wealth of parent-report research shows adaptive functioning difficulties in autistic children, with parent-report influenced by a number of child factors. Adaptive functioning in autistic children is known to vary across settings; however, no research has yet explored factors influencing education professional-report. This study investigated the rate and profile of impairment, and child factors influencing education professional-reported adaptive skills in 248 autistic children. Twelve children were < 3 years (min age for available normative data on the adaptive function measure), so were removed from the analyses. Results replicated parent-literature; adaptive skills were negatively associated with age and informant-reported autism severity, and positively associated with nonverbal ability and expressive language. Adaptive functioning is important for real-world outcomes, e.g. educational attainment, independence, and support needs. Improving our understanding of adaptive functioning in the education context may support opportunities for shared learning and enhance personalised support .

LAY ABSTRACT: Anxiety is common in autistic children. Research shows that this may be related to intolerance of uncertainty, which is a tendency to react negatively to uncertain situations. Understanding when, why and how autistic children respond to uncertainty is important in the development of anxiety programmes. We asked 53 (including 3 dyads) parents of autistic children about the types of uncertain situations that cause difficulties for their child and how uncertainty impacts on daily life for them and their families. We found that uncertain situations made autistic children and their families feel sad, worried, frustrated and angry through the themes: child's reactions to uncertainty, trying to reduce uncertainty, the impact of difficulties with uncertainty, the impact of uncertainty on parenting and the impact on parents. There are lots of situations that are anxiety provoking for autistic children because of uncertainty, such as school. Programmes to reduce anxiety and increase autistic children's ability to cope with everyday uncertain situations could improve quality of life for autistic children and their families.

BACKGROUND: Restricted and repetitive behaviours vary greatly across the autism spectrum, and although not all are problematic some can cause distress and interfere with learning and social opportunities. We have, alongside parents, developed a parent group based intervention for families of young children with autism, which aims to offer support to parents and carers; helping them to recognise, understand and learn how to respond to their child's challenging restricted repetitive behaviours. METHODS: The study is a clinical and cost-effectiveness, multi-site randomised controlled trial of the Managing Repetitive Behaviours (MRB) parent group intervention versus a psychoeducation parent group Learning About Autism (LAA) (n = 250; 125 intervention/125 psychoeducation; ~ 83/site) for parents of young children aged 3-9 years 11 months with a diagnosis of autism. All analyses will be done under intention-to-treat principle. The primary outcome at 24 weeks will use generalised estimating equation (GEE) to compare proportion of children with improved RRB between the MRB group and the LAA group. The GEE model will account for the clustering of children by parent groups using exchangeable working correlation. All secondary outcomes will be analysed in a similar way using appropriate distribution and link function. The economic evaluation will be conducted from the perspective of both NHS costs and family access to local community services. A 'within trial' cost-effectiveness analysis with results reported as the incremental cost per additional child achieving at least the target improvement in CGI-I scale at 24 weeks. DISCUSSION: This is an efficacy trial to investigate the clinical and cost-effectiveness of a parent group based intervention designed to help parents understand and manage their child's challenging RRB. If found to be effective, this intervention has the potential to improve the well-being of children and their families, reduce parental stress, greatly enhance community participation and potential for learning, and improve longer-term outcomes.

BACKGROUND: Achieving adequate nutrition in preterm infants is challenging. The post-discharge period may be critical for influencing growth and cognitive outcomes. We studied the effects of post-discharge nutrition on childhood cognition. METHODS: Preterm-born children were randomized at ~36 weeks corrected age (CGA) to either preterm formula (PTF) or term formula (TF) until 6 months, or PTF until 40 weeks CGA, then TF until 6 months (crossover group). Childhood cognition was assessed using the short form Wechsler Intelligence Scale for Children III, allowing computation of full-scale intelligence quotient (FSIQ) and four-factor index scores; verbal comprehension, freedom from distractibility (FDI), perceptual organization (POI), and processing speed (PSI). RESULTS: Ninety-two children were recruited (mean 10.1 years). FSIQ did not differ by group. PTF-fed children had 10-point higher PSI (p = 0.03) compared to crossover. Faster weight gain from term to 12 weeks CGA was associated with 5-point higher FSIQ (p = 0.02) and four-point higher POI (p = 0.04). Infant head growth was positively associated with FSIQ (+3.8 points, p = 0.04) and FDI (+6 points, p = 0.003). CONCLUSIONS: While there is no long-term impact of post-discharge macronutrient enrichment on childhood cognition, greater weight and head growth in specific epochs is associated with better outcomes. Further studies are needed to determine optimal early diet in preterm infants. IMPACT: Achieving adequate nutrient intakes in preterm infants before and after hospital discharge is challenging. Nutrient intakes prior to discharge affect later cognitive and metabolic outcomes. Follow-up of a randomized controlled trial shows no cognitive benefit in later childhood from a more nutrient-dense formula compared to standard formula after hospital discharge. Growth in the first year of life is strongly correlated with childhood cognition and emphasizes the importance of nutrition in early life.

We acknowledge Green's viewpoint and agree that currently the literature does not support the validity of PDA as an independent syndrome. However, the controversy is real and exists for a reason. We therefore argue that it is important to move beyond labelling and the potentially unhelpful implications of discussion around whether or not it is a condition, diagnosis or a co-morbid condition, to a point of recognition of the phenomenon. We argue that what we need is more accurate description of these behaviours and better measurement to allow us to answer key questions about this phenomenon, whatever we name it. In our paper (Stuart et al, Child and Adolescent Mental Health, 2019) and response, we are trying to move the debate on from opinion and anecdote to be more data-driven, which hopefully leads to increased identification of what research needs to be done. We build on this argument by outlining our second proposed and yet to be published paper exploring the role that IU has in the relationship between ASD, PDA (however we label this) and anxiety.

BACKGROUND: Pathological demand avoidance (PDA) is a proposed subtype of autism spectrum disorder (ASD), characterised by extreme avoidance of demands. Demand avoidant behaviour has been proposed to be driven by an anxious need to be in control, although has never been explicitly studied. Emerging evidence suggests intolerance of uncertainty (IU) and anxiety may explain the behaviours seen in ASD. We propose these concepts may be useful starting points for furthering understanding of PDA. METHODS: In Study 1, quantitative methods examined the relationship between PDA, IU and anxiety using data collected in an online survey (N = 214). The sample included cases with clinically diagnosed PDA (n = 69) and those with no clinical diagnosis but parent-identified features of PDA (n = 151). 'Children with a diagnosis of PDA scored significantly higher on the IUS-P (t(212) = 2.45, p < .05) compared to those without a diagnosis of PDA. PDA diagnosis did not impact on scores on any other measure.' In Study 2, a selection of Study 1 participants (n = 11) were followed up with a telephone interview to gain descriptive data relating to PDA and its association with IU and anxiety. RESULTS: Regression analyses indicate that demand avoidant behaviour can be conceptualised in part as a possible attempt to increase certainty and predictability to alleviate increasing anxiety. Children and young people with PDA employed varying strategies to manage IU depending on the level of demand presented and degree of anxiety generated. These strategies can be represented by different features of the behaviour profile seen in PDA (control behaviour, withdrawal to fantasy, and meltdown). These behavioural features of PDA showed differential relationships with IU and anxiety, although all were predicted by IU, only meltdown demonstrated a mediation effect by anxiety. CONCLUSIONS: This study represents one of the first attempts to conceptualise and understand the behavioural features of the PDA profile in children and young people. It builds upon emerging evidence from the ASD literature that IU is a relevant construct for conceptualising demand avoidant behaviour in children who show PDA behaviour. This has potential clinical implications for the assessment and management of PDA in children and young people.

This paper is in response to the commentary written by Richard Woods in which he attempts to provide support for his Monotropism autism theory and the research indicating that Demand Avoidance Phenomena may not be developmentally persistent (Woods, 2019). We acknowledge the continuing controversy around the proposed construct of PDA and the clinical dilemma faced by professionals, within the United Kingdom, following increased demand from families seeking assessment and support. We appreciate that research on this topic is scarce and understanding of PDA behaviours remains limited and that methodological improvements are required. However, it is important to remember that anxiety, which often has an onset in middle childhood and adolescence, is a major risk factor for mental health difficulties. Therefore, treatments targeting underlying and potentially modifiable mechanisms rather than anxiety symptoms may be more likely to be effective.

A systematic literature review was undertaken to ascertain the prevalence of self-harm and suicidal behaviour in children and young people under 18 years old with a diagnosis of autism spectrum disorder (ASD), with or without an intellectual disability. There was variation in the reported prevalence rates but results suggested that rates of both self-harm and suicidal behaviour may be elevated in ASD compared to the general population. This is in keeping with literature relating to autistic adults but in contrast to conclusions of a previous systematic review. This review highlights the need for further research to explore the experience of self-harm and suicidal behaviour in autistic children and young people.

BACKGROUND: Anxiety is a common diagnosis in children with autism spectrum disorder (ASD). One key mechanism underlying anxiety is intolerance of uncertainty, which is a tendency to react negatively on an emotional, cognitive, and behavioural level to uncertain situations and events. We developed the first intervention programme specifically targeting intolerance of uncertainty in children with ASD: Coping with Uncertainty in Everyday Situations (CUES). CUES is a parent group intervention providing parents of children with ASD with strategies to increase tolerance to uncertainty for their children in everyday situations. The principal aims of the current study are: 1) evaluate the acceptability and feasibility of delivering CUES to parents who have a child with ASD and anxiety; and 2) inform the design of a fully powered trial. METHOD: This is a feasibility and acceptability single-blind pilot randomised controlled trial comparing CUES (intervention) to a brief psychoeducation, emotional literacy, and relaxation programme (enhanced services as usual). Participants will be assessed at baseline and followed-up immediately post-treatment, and at 12 and 26 weeks post-treatment. Parents who have a child with ASD and anxiety (aged 6-16 years) will be invited to take part in the study and written parental informed consent and child assent will be obtained. Participants will be recruited from the National Health Service mental health teams in the UK. Sixty participants will be randomised to either intervention or enhanced services as usual in a 1:1 ratio. DISCUSSION: The present study will provide evidence on the acceptability of the CUES intervention to parents and children, and the feasibility of recruitment and delivery to inform the design and sample size for a full-scale randomised controlled trial. Qualitative data will be obtained to understand how feasible CUES is for families, and the experiences of participants regarding their experiences of the intervention.

We examined the feasibility and acceptability of using an immersive virtual reality environment (VRE) alongside cognitive behaviour therapy (CBT) for young people with autism experiencing specific phobia. Thirty-two participants were randomised to treatment or control. Treatment involved one session introducing CBT techniques and four VRE sessions, delivered by local clinical therapists. Change in target behaviour was independently rated. Two weeks after treatment, four treatment participants (25%) and no control participants were responders; at 6 months after treatment, six (38%) treatment and no control participants were responders. At 6 months post-treatment, symptoms had worsened for one treatment and five control (untreated) participants. Brief VRE exposure with CBT is feasible and acceptable to deliver through child clinical services and is effective for some participants.

Pathological (or extreme) demand avoidance is a term sometimes applied to complex behaviours in children within-or beyond-autism spectrum disorder. The use of pathological demand avoidance as a diagnosis has, at times, led to altered referral practice and misunderstandings between professionals and the families of patients. In our Viewpoint, we reviewed the current literature and conclude that the evidence does not support the validity of pathological demand avoidance as an independent syndrome. Nevertheless, the use of the term highlights an important known range of co-occurring difficulties for many children with autism spectrum disorder that can substantially affect families. We explore how these difficulties can best be understood through understanding of social, sensory, and cognitive sensitivities in autism spectrum disorder, identification of frequently occurring comorbid conditions, and assessment of how these problems interact within the child's social environment. Such understanding should then inform individualised management strategies for children and families, and in social settings, such as education. It is crucial that a shared understanding is achieved between professionals and families in this area.

BACKGROUND: Prior evidence shows that behaviours closely related to the intervention delivered for autism are amenable to change, but it is more difficult to generalise treatment effects beyond the intervention context. We test an early autism intervention designed to promote generalisation of therapy-acquired skills into home and school contexts to improve adaptive function and reduce symptoms. A detailed mechanism study will address the process of such generalisation. Objective 1 will be to test if the PACT-G intervention improves autism symptom outcome in the home and school context of the intervention as well as in the primary outcome research setting. Objective 2 will use the mechanism analysis to test for evidence of acquired skills from intervention generalizing across contexts and producing additive effects on primary outcome. METHODS/DESIGN: This is a three-site, two-parallel-group, randomised controlled trial of the experimental treatment plus treatment as usual (TAU) versus TAU alone. Children aged 2-11 years (n = 244 (122 intervention/122 TAU; ~ 82/site) meeting criteria for core autism will be eligible. The experimental intervention builds on a clinic-based Pre-school Autism Communication Treatment model (PACT), delivered with the primary caregiver, combined with additional theory- and evidence-based strategies designed to enhance the generalisation of effects into naturalistic home and education contexts. The control intervention will be TAU. PRIMARY OUTCOME: autism symptom outcome, researcher-assessed using a standardised protocol. SECONDARY OUTCOMES: autism symptoms, child interaction with parent or teacher, language and reported functional outcomes in home and school settings. Outcomes measured at baseline and 12-month endpoint in all settings with interim interaction measurements (7 months) to test treatment effect mechanisms. Primary analysis will estimate between-group difference in primary outcome using analysis of covariance with test of homogeneity of effect across age group. Mechanism analysis will use regression models to test for mediation on primary outcome by parent-child and teaching staff-child social interaction. DISCUSSION: This is an efficacy and mechanism trial of generalising evidence-based autism treatment into home and school settings. It will provide data on whether extending treatment across naturalistic contexts enhances overall effect and data on the mechanism in autism development of the generalisation of acquired developmental skills across contexts.

BACKGROUND: Early intervention for autism spectrum disorder (ASD) tends to focus on enhancing social communication skills. We report data collected via focus group discussions as part of a feasibility and acceptability pilot randomized controlled trial (RCT) about a new parent group intervention to manage restricted and repetitive behaviours (RRB) in young children with ASD. METHODS: The focus groups were led by two independent facilitators and followed a semi-structured topic guide with the aim of considering three key topics: experiences of participating in a RCT, opinions about the intervention and the impact of the intervention on the participants, their children and the family. RESULTS: Fourteen participants attended the focus groups. Most participants reported that they had little knowledge of RRB before attending the intervention and that it had had a positive impact on them, their children and their family. CONCLUSION: The findings support the view that there is an unmet need for a parent-mediated intervention focusing on RRB.

Early intervention for autism spectrum disorder (ASD) tends to focus on enhancing social-communication skills. We report the acceptability, feasibility and impact on child functioning of a new 8 weeks parent-group intervention to manage restricted and repetitive behaviours (RRB) in young children with ASD aged 3-7 years. Forty-five families took part in the pilot RCT. A range of primary and secondary outcome measures were collected on four occasions (baseline, 10, 18 and 24 weeks) to capture both independent ratings and parent-reported changes in RRB. This pilot established that parents were willing to be recruited and randomised, and the format and content of the intervention was feasible. Fidelity of delivery was high, and attendance was 90 %. A fully powered trial is now planned.

AIM: To investigate the acceptability and feasibility of adapted group therapy for anxiety in children with autism spectrum disorder in a pilot randomised controlled trial. METHOD: A total of 32 children aged 9-13 years were randomised to immediate or delayed therapy using the 'Exploring Feelings' manual (Attwood, 2004). Child and parent groups were run in parallel, for seven weekly sessions, under the supervision of experienced psychologists. The primary blinded outcome measures addressed change in overall functioning and in severity of the primary anxiety diagnosis after 3 months. RESULTS: Children met diagnostic criteria for 1-6 anxiety disorders (median 3). At end point, both parents and children in the immediate therapy group were more likely to report a reduction in anxiety symptoms. Fidelity of delivery of the group therapy was high, and attendance was 91%. CONCLUSIONS: This pilot trial established that children and families were willing to be recruited and randomised, the outcome measures were acceptable, the format and content of the groups were feasible within UK child and adolescent mental health services, the intervention was appreciated by families and attrition was very small.
