Internalising symptoms are elevated in autism compared to the general population. Few studies have investigated emotional dysregulation (ED) as a potential mediator between specific transdiagnostic processes and anxiety and depression symptoms in autistic youth. In a sample of 94 autistic young people aged 5–18 years referred to a specialist clinic...

Up to 50% of autistic people experience co-occurring anxiety, which significantly impacts their quality of life. Consequently, developing new interventions (and/ or adapting existing ones) that improve anxiety has been indicated as a priority for clinical research and practice by the autistic community. Despite this, there are very few effective, e...

Autistic children and young people experience poorer mental health and well-being compared to their non-autistic peers. Navigating the complex social, academic, procedural and sensory aspects of school may be particularly challenging for autistic young people and contribute to poorer mental well-being. The COVID-19 pandemic caused unprecedented sch...

The present study aimed to examine anxiety profiles among children and adolescents on the autism spectrum. It further aimed to characterize the association between the identified anxiety profiles and key clinical and developmental variables. The Spence Children's Anxiety Scale‐Parent Version (SCAS‐P) data from a large international pooled sample of...

Cognitive behavior therapy (CBT) is a goal-focused, usually short-term therapy that integrates cognitive and behavioral modalities. CBT aims to change unhelpful thinking patterns and behaviors and develop more balanced ways of thinking about, and responding to, distressing experiences and situations. As rates of mental health difficulties are high...

Background Internalising (anxiety and low mood) and externalising (aggressive or outburst behaviours, and irritability) difficulties are very common in autism spectrum disorder (ASD) across the life span, relatively stable over time and often associated with poorer quality of life. Understanding the cognitive mechanisms underlying internalising and...

Since its inception in 1980, the term PDA has generated much debate, indeed, arguably few subjects have generated such controversy in the neurodevelopmental literature. However research in the area is moving into more practical arenas, including trying to understand why some children present with problematic demand avoidant behaviour, in order to p...

Anxiety is common in autism spectrum disorder. Many anxiety symptoms in autism spectrum disorder are consistent with Diagnostic and Statistical Manual of Mental Disorders (5th ed.) anxiety disorders (termed “common” anxieties), but others may be qualitatively different, likely relating to autism spectrum disorder traits (herein termed “autism-relat...

Anxiety has been recognized as a significant presenting feature associated with autism spectrum disorder (ASD) since the first clinical descriptions of ASD, with more recent prevalence studies confirming elevated rates of anxiety in this population across the lifespan compared with the general population. However, elevated anxiety symptoms do not f...

Mental imagery has been implicated in anxiety disorders in adults, but has not been investigated in child and adolescent populations. Anxiety is highly prevalent in autism spectrum disorder (ASD), and as people with ASD are often thought of as 'visual thinkers', the potential role of distressing imagery in children with ASD merits exploration. Part...

Anxiety-related difficulties are common in ASD, but measuring anxiety reliably and validly is challenging. Despite an increasing number of studies, there is no clear agreement on which existing anxiety measure is more psychometrically sound and what is the factor structure of anxiety in ASD. The present study examined the internal consistency, conv...

The aims of this study were two-fold; firstly, to investigate whether self-report measures are useful and reflect parent-reported psychiatric symptoms in children with autism spectrum disorder (ASD), and secondly, to investigate whether children with ASD are able to access and report their cognitions, a prerequisite skill for cognitive behavior the...

Young people with an autism spectrum disorder (ASD) are more likely to have heightened levels of anxiety compared with their typically developing (non-ASD) peers. The reasons for this are poorly understood, and there has been little research investigating the cognitive correlates of anxiety in individuals with ASD. Typically developing youth with a...

Mental health problems are increasingly being recognised as a significant health need for people with autism spectrum disorder, but few specialist services are available. This study explored parents’ experiences of a specialist autism spectrum psychological intervention service located within a broader Neurodevelopmental and Social Communication Di...

Anxiety disorders are common among children and young people with Autism Spectrum Disorders (ASD). Despite growing knowledge about the prevalence, phenomenology and treatment of anxiety disorders, relatively little is understood about the nature and impact of anxiety in this group and little is known about autism-specific factors that may play a ro...

Although the high prevalence of mental health problems in individuals with autism spectrum disorders (ASD) is increasingly recognised, there remains a lack of evidence-based assessment and treatment methods to guide clinical practice. This service evaluation identified current practices among 12 child clinical psychologists across the South London...

It is now well established that the prevalence of mental health difficulties in individuals with autism spectrum disorders (ASD) is considerably higher than in the general population. With recent estimates of the prevalence of autism spectrum disorders being as high as one percent, increasing numbers of children and young people are presenting to l...

This chapter describes the socio-cultural settings and the relevant health care services within which the European Early Promotion Project was conducted, in order to render the interpretation of study results more meaningful and to justify cross-cultural differences. Greece, Cyprus and Serbia are characterised by lower social expenditure, welfare p...
