Variation in the Profile of Anxiety Disorders in Boys with an ASD According to Method and Source of Assessment

Evaluating the Use of Self-reported Measures in Autistic Individuals in the Context of Psychiatric Assessment: A Systematic Review

The current review examined the use of self-report measures in autistic individuals in the context of psychiatric assessments. It focused on inter-rater agreement, internal consistency, test-retest reliability, and criterion validity with clinical diagnoses. It also gathered information on constructs measured, the nature of the samples, and the quality of the studies. Thirty-six out of 10,557 studies met inclusion criteria. We found that the majority of studies (1) targeted young people with average or above average cognitive abilities, (2) measured anxiety symptoms, and (3) evaluated parent-child agreement. More studies are needed on individuals with lower cognitive abilities, adults, and other constructs. Studies assessing criterion validity and test-retest reliability are also needed.

"My cheeks get red and my brain gets scared": A computer assisted interview to explore experiences of anxiety in young children on the autism spectrum

BACKGROUND

Anxiety symptoms are common in children on the autism spectrum and may be present at an early age. While a multi-informant approach is considered best practice in the assessment of anxiety, self-reports from young children on the autism spectrum are rarely included.

AIMS

The aim of this study was to utilise a computer-assisted interview procedure incorporating visual prompts to elicit the viewpoints of children about their experiences of anxiety.

METHODS AND PROCEDURES

Ten children aged 5-8 years who were diagnosed on the autism spectrum completed the interview. Directed content analysis was used to explore the data generated in the interview.

OUTCOMES AND RESULTS

A wide range of situations that trigger anxiety, and responses to anxiety, were reported across the participant group. These responses may be unrecognised as anxiety by others. The children provided positive feedback on the use of the computer-assisted interview.

CONCLUSIONS AND IMPLICATIONS

The child's own self-report can inform parents and professionals of the situations which make them more or less anxious and the behaviours that they use to communicate their anxiety in that specific situation. The use of a computer-assisted interview may be an effective method to support self-report of anxiety-related experiences for young children on the autism spectrum.

Is Bullying Associated with Emerging School Refusal in Autistic Boys?

The experience of being bullied is widespread among autistic youth. Relatively little empirical work has been done on the relationship between the bullying of these youth and school refusal (SR). This study of 67 school-age autistic boys (M = 11.7 years, SD = 2.3 years) examined several factors that may contribute to SR. Data regarding boys' age, generalised anxiety disorder (GAD), major depressive disorder (MDD), key ASD diagnostic criteria, and frequency of being bullied were collected. Results indicated that, while boys displaying emerging SR also had significantly higher GAD and MDD than boys without emerging SR, only the frequency of being bullied made a significant contribution to emerging SR. Implications for prevention and treatment of SR among autistic youth are discussed.

Obsessive-Compulsive Disorder in Autism Spectrum Disorder Across the Lifespan

Obsessive-compulsive disorder is a relatively common disorder seen in autism spectrum disorder across the lifespan. Many obsessive-compulsive disorder symptoms can present similarly to the core features of autism spectrum disorder and it is often difficult to differentiate between obsessive-compulsive disorder and stereotypic behaviors or restricted interests in autism spectrum disorder. However, there are differences between the 2 disorders. This article is a review of the current literature with the goal of helping the clinician to diagnose and treat obsessive-compulsive disorder in a patient with autism spectrum disorder.

Cluster analysis of autism spectrum disorder symptomatology: Qualitatively distinct subtypes or quantitative degrees of severity of a single disorder?

The decision to collapse several related disorders into a single diagnosis of Autism Spectrum Disorder (ASD) generated significant controversy and debate. There has been mixed evidence as to whether various ASD subtypes are qualitatively distinct or if they exist on a spectrum of symptom severity. The present study conducted a two-step cluster analysis of major ASD symptoms in a sample of 147 young males with ASD aged between 6yr and 18yr with IQ > 70. Results indicated that a two-cluster solution (high and low severity of ASD symptomatology) was reliable and valid. Further, the construct of challenging behaviour was not a necessary component of the two-cluster solution, verifying the new conceptualisation of ASD. Further replication of these findings with other subsets of individuals with ASD is needed.

Anxiety-related symptomatology in young children on the autism spectrum

Anxiety symptomatology is frequently reported in autistic children, and the prevalence of anxiety disorder is estimated at around 40%. However, most studies have focused upon children of age 8 years or above, so little is known about early signs of anxiety in younger children with autism. This study sought to describe anxiety-related symptomatology in 95 5- to 6-year-old autistic children using the Anxiety Scale for Children with Autism Spectrum Disorder. Wide variability was found in levels of symptomatology with the most frequently reported items within the ‘uncertainty’ subscale and the least frequently reported items in the ‘anxious arousal’ subscale. Comparisons of those with scores less than or greater than 70 on adaptive behaviour suggests some influence of ability on presentation of anxiety-related symptomatology.

Restricted, Repetitive Behaviors in Autism Spectrum Disorder and Obsessive-Compulsive Disorder: A Comparative Review

This review paper critically examines literature regarding restricted and repetitive behaviors (RRBs) in Autism Spectrum Disorder (ASD) and Obsessive-Compulsive Disorder (OCD). The similar behavioral profiles of these disorders presents the potential for confusion regarding diagnoses and intervention efforts. As such, this review highlights the similarities and differences between RRBs in ASD and OCD. The developmental trajectories of RRBs are presented, followed by an exploration of three constructs implicated in RRB manifestation: anxiety, executive functioning, and sensory phenomena. While RRBs tend to develop with some similarity in both disorders, the differing role of anxiety highlights important distinctions between ASD and OCD. We urge researchers and clinicians to think critically about the dimensions that affect RRB presentation. Future research should use this review as a starting point to further elucidate the differences between RRBs in these two populations.

The association between parents' ratings of ASD symptoms and anxiety in a sample of high-functioning boys and adolescents with Autism Spectrum Disorder

BACKGROUND

The relationship between symptoms of Autism Spectrum Disorder (ASD) and Generalised Anxiety Disorder (GAD) is complex and sometimes confounding. However, exploration of that relationship has significant potential to assist in treatment or avoidance of GAD by identifying ASD-related behaviours as 'targets' for intervention with anxious children as well as for preventative treatments that could be implemented into daily routines before children become anxious. To further understanding of this relationship, the association between parent-ratings of their sons' ASD symptoms and GAD symptoms was investigated in two samples of boys with high-functioning ASD.

METHODS

Parents of a sample of 90 pre-adolescent (M age=8.8yr) and 60 adolescent males (M age=14.6yr) completed the Social Responsiveness Scale (SRS) and the GAD subscale of the Child and Adolescent Symptom Inventory (CASI-4 GAD) about their sons.

RESULTS

Pre-adolescents had significantly higher SRS scale scores than adolescents. For pre-adolescents, high levels of tension in social situations were associated with 3.5-times greater likelihood of having GAD; for adolescents, experiencing difficulty in changes in routine was associated with a 10-fold increase in risk of GAD.

CONCLUSIONS

In addition to focussing upon GAD itself, preventative and treatment options aimed at reducing GAD or its risk might profitably recognise and focus upon these two aspects of ASD that are different across the two age groups but each of which was significantly associated with GAD severity and prevalence in this study.

Anxiety Levels in Children with Autism Spectrum Disorder: A Meta-Analysis

The aim of the current study was to meta-analytically examine whether anxiety levels in children with autism spectrum disorders (ASD) are elevated. A total of 83 articles were selected from a systematic literature search and were included in the meta-analyses. Results demonstrated that children with ASD had higher anxiety levels compared to typically developing children, and this difference increased with IQ. Youth with ASD also tended to have higher anxiety levels compared to clinically referred children, and this difference increased with age. Children with ASD had higher anxiety levels compared to youth with externalizing or developmental problems, but not when compared to youth with internalizing problems. The study findings highlight the importance of more research in order to fully understand the nature and development of anxiety in children with ASD. More specifically, the results suggest that especially high-functioning adolescents with ASD may be at risk for developing anxiety disorders. Therefore, it seems important to carefully follow and monitor children with ASD transcending to adolescence.

How are Sensory Features associated with seven anxiety disorders in boys with Autism Spectrum Disorder?

The association between Sensory Features (SF) and seven anxiety disorders was investigated using self-reports and parental reports about 140 young males with an Autism Spectrum Disorder (ASD). Although there were significant correlations between SF and self- and parent-ratings of some of the seven anxiety disorders, overall, SF was found to have an inconsistent association across the seven anxiety disorders and this was also found for the 8 symptoms of Generalised Anxiety Disorder. These data challenge the practice of assessing SF and anxiety via global measures and argue for individualized disorder-specific assessments to develop more effective diagnoses and treatments for the effects of SF.

Is afternoon cortisol more reliable than waking cortisol in association studies of children with an ASD?

Salivary cortisol may be used as a biomarker of stress and anxiety in children with an Autism Spectrum Disorder (ASD) and is particularly valuable in studies of the association between stress-related cortisol concentrations and other factors such as comorbid disorders or aspects of the ASD phenotype. Although protocols for the collection of cortisol shortly after waking are often based on the assumption of the presence of a diurnal rhythm in cortisol, that rhythm may not be as reliable in children with an ASD as in non-ASD children. Alternatively, collecting cortisol during the afternoon may represent a more reliable procedure with less inter-participant variability.
