RESUMO
PURPOSE OF REVIEW: This review aims to give an update on research in the past 5 years regarding the co-occurrence, assessment and treatment of obsessive compulsive disorder (OCD) in individuals with autism spectrum disorder (ASD). RECENT FINDINGS: Recent findings affirm not only a high prevalence of OCD amongst individuals with ASD (and vice versa) but also notable variability in assessment methods and results. There remain limited validated measures with which to assess OCD in those with ASD, which are often difficult to differentiate. Adapted and function-based CBT programs specifically designed for ASD demonstrate promising results, but additional randomised controlled trials are needed. Though some exciting progress has been made in the area of treatment of OCD in ASD, progress remains hampered by inconsistent measurement of OCD in ASD. Future priorities include development of brief, valid assessment tools and determining the efficacy and effectiveness of newly developed and adapted treatment programs.

Autistic traits are associated with differential processing of emotional and social cues. By contrast little is known about the relationship of autistic traits to socio-emotional memory, though research suggests an integral relationship between episodic memory processes and psychosocial well-being. Using an experimental paradigm, we tested if autistic traits moderate the effects of negative emotion and social cues on episodic memory (i.e. memory for past events). Young adults (N = 706) with varied levels of self-reported autistic traits (24% in clinical range) encoded images stratified by emotion (negative, neutral) and social cues (social, non-social) alongside a neutral object. After 24 h, item memory for images and associative memory for objects was tested. For item memory, after controlling for anxiety, a small effect emerged whereby a memory-enhancing effect of social cues was reduced as autistic traits increased. For associative memory, memory for pairings between neutral, but not negative, images reduced as autistic traits increased. Results suggest autistic traits are associated with reduced ability to bind neutral items together in memory, potentially impeding nuanced appraisals of past experience. This bias toward more negative, less nuanced memories of past experience may represent a cognitive vulnerability to social and mental health challenges commonly associated with autistic traits and a potential intervention target.

LAY ABSTRACT: The types of outcomes studied in children on the autism spectrum include clinical characteristics, such as social functioning, communication, language, or autism symptoms. Research that measures these outcomes at multiple timepoints is useful to improve our understanding of what to expect as children develop. In trajectory studies, researchers assess outcomes at three or more timepoints. This method has advantages over two-timepoint studies because it allows researchers to describe changes in the speed of development, such as accelerations, plateaus, or slowdowns. We identified and reviewed 103 published trajectory studies in children (to age 18 years) with an autism diagnosis. Importantly, we did not include studies of treatments or their effects, nor did we summarize the results of studies. Instead, this review summarizes the characteristics of the available published research, including the methods used, the many different outcomes that have been studied over time and the ages over which they have been studied. This summary may be of interest to autistic people and caregivers (parents) who want to know about the existence of research that provides answers about what to expect during an autistic child's development. We have recommended that future trajectory research efforts try to make up for the lack of studies from low- and middle-income countries; that more attention is given to the following outcomes that are meaningful to caregivers and autistic people; and to try to fill in the age gaps where more outcome-specific data are needed.

Negative emotion enhances item memory but may reduce associative memory. Social information may also enhance memory, yet how social and emotional cues combine to affect memory for focal and surrounding details is unknown. Gender differences may also exist, but whether women and men encode and remember negative and social information differently is unclear. This study examines how social information contributes to or interacts with emotion to influence item and associative memory, and whether gender plays a role in how social and/or emotional information is recognized. Discovery and replication samples (N = 706) were recruited. Stimuli included (1) images with varying social and emotional content categorized into four conditions: negative social, negative nonsocial, neutral social, neutral nonsocial and (2) neutral images of objects paired with target stimuli to assess associative memory. Participants viewed the image pairings (Encoding). Twenty-four hours later, item and associative recognition memory were tested. Item recognition memory was better for negative vs. neutral and social vs. nonsocial images. By contrast, associative recognition memory was worse for negative vs. neutral, but better for social vs. nonsocial images. Finally, women demonstrated similar item memory performance compared to men but better associative recognition memory performance overall compared to men. Emotional and social cues impart distinct effects on how we form holistic episodic memories, highlighting the importance of considering these critical factors when striving to understand how and what we remember.

People who learn the outcome to a situation or problem tend to overestimate what was known in the past-this is hindsight bias. Whereas previous research has revealed robust hindsight bias in the visual domain, little is known about how outcome information affects our memory of others' emotional expressions. The goal of the current work was to test whether participants exhibited hindsight bias for emotional faces and whether this varied as a function of emotion. Across five experiments, participants saw images of faces displaying different emotions. In the foresight phase, participants watched several emotional faces gradually clarify from blurry to clear. Once participants believed they knew what emotion the face was exhibiting, they identified the emotion from several options (e.g., angry, disgusted, happy, scared, surprised). In the hindsight phase, participants saw clear versions of each face before stopping the clarification at the point at which they previously identified the emotional expression. On average, participants exhibited hindsight bias for all emotions except happy faces (i.e., they indicated that they identified the emotional expressions at a blurrier point in hindsight than they had in foresight). A multinomial processing tree model of our data revealed that this was not due to participants' better recollection of foresight judgments for happy faces compared to the other emotions. Additionally, participants showed a smaller reconstruction bias for happy faces than the other emotions. We discuss the social implications of these findings as well as the potential for this paradigm to be used across cultures and ages. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Co-occurring anxiety in children on the autism spectrum is associated with greater social challenges, including poorer social skills and relationships, which may influence the severity and presentation of anxiety symptoms, particularly social anxiety. The current study used Bayesian network analytics (Williams & Mulder, 2020) and a multimethod approach to examine (a) how different facets of social functioning relate to one another and to anxiety severity and comorbidity, (b) which facet(s) are most influential and thus may represent optimal targets for intervention, and (c) how social functioning relates to the presentation of social fears in a large treatment-seeking sample of autistic children with anxiety disorders (n = 191, 7-13 years). Results indicated strong associations among measures of social ability (i.e., theory of mind [ToM], social motivation, friendship attainment) and among measures of social integration (i.e., bullying, interpersonal and peer difficulties), with only bullying demonstrating a significant association with anxiety. ToM was the most interconnected variable in the network, and social motivation demonstrated the strongest individual connections with other variables, particularly with other facets of social ability. Socially anxious children with impaired ToM were less likely to express fears of negative evaluation, resulting in a distinct diagnostic presentation of social fears. Findings suggest that social motivation and ToM may represent important targets for intervention for autistic children with co-occurring anxiety. Further, social-cognitive difficulties associated with autism, like ToM, may play a role in distinct manifestations of anxiety in these youth.

INTRODUCTION: Longitudinal trajectory methods, featuring outcome assessments at three or more time points, are increasingly being used as appropriate approaches to understand developmental pathways of people on the autism spectrum across the lifespan. Understanding the scope of this rapidly expanding body of research can help inform future trajectory studies and identify areas for potential meta-analysis as well as key evidence gaps. We present the protocol for a scoping review whose objective is to identify and summarise the scope of research that uses a longitudinal trajectory study design to examine development in children diagnosed with autism. Specifically, we will identify outcome domains and age intervals that have been well characterised, areas where further research is needed and the historical use of various longitudinal trajectory analytical approaches. METHODS AND ANALYSIS: We outline the methods for the proposed scoping review according to the framework outlined by Arksey and O'Malley, with subsequent clarifications and enhancements by other authors. Using a search strategy developed by a medical librarian, we will search six databases for relevant publications. Titles and abstracts will be screened in duplicate, followed by full-text screening. Data extraction fields developed predominantly a priori from a set of guiding subquestions will be used to chart relevant data. The findings will include quantitative aggregate summaries, narrative summaries, and appraisal of trajectory studies according to our methodological subquestions. We will consult autistic self-advocate and parent-caregiver stakeholders to facilitate interpretation of the findings. ETHICS AND DISSEMINATION: Research ethics approval is not required for this scoping review. The results will be presented to researcher, care professional, policy-maker and stakeholder audiences at local and international conferences, other dissemination activities and published in a peer-reviewed journal.

Research on anxiety in children and adolescents with autism spectrum disorder (ASD) has burgeoned in the past 15 years. Most of the research has focused on school-age children, ages 6 to 18 years. Yet, recent studies suggest that anxiety can emerge in young children, under 6 years, with ASD. This scoping review synthesized the literature on anxiety in young children with ASD. Three domains of anxiety research were reviewed: (a) prevalence/severity, phenomenology, and course; (b) correlates; and (c) treatment. Four online databases were searched from the start of the database until March 2020. Keywords pertaining to anxiety, autism, and young children were entered. The search identified 44 articles for inclusion. These studies varied with respect to sample source, informants, and measures to assess anxiety. The overall prevalence of anxiety ranged from 1.6 to 62%. Sixteen of 17 studies found that young children with ASD had higher levels of anxiety compared to various control groups. A variety of DSM anxiety symptoms and disorders were present in young children with the most common symptoms being specific, social, and generalized fears. Correlates of anxiety included sensory over-responsivity, sleep disturbance, aggression/defiance, and attention deficit/hyperactivity disorder. Three cognitive behavioral treatment studies for anxiety and one developmental intervention targeting ASD symptoms showed promise in reducing anxiety. Findings indicate an early emergence of anxiety in some children with ASD. Further research on the measurement, pathophysiology, and treatment of anxiety in early childhood is critical to improving outcomes in children with ASD. LAY SUMMARY: This scoping review synthesizes the literature on anxiety in young children with autism spectrum disorder (ASD). Results indicate that children with ASD have higher levels of anxiety than children without ASD. Potential factors that could be contributing to anxiety include sensory, sleep, and behavioral problems. Preliminary studies show that anxiety can improve with cognitive behavioral treatment. These findings suggest that research on anxiety in young children with ASD should be prioritized to improve mental health outcomes.

This study investigated rates of suicidal ideation (SI) and suicidal and/or self-injurious behaviour (SSIB) reported by parents on the Child Behavior Checklist for 178 children with ASD over four annual assessments (ages 7-11 years). Analyses examined the frequency and persistence of SI and SSIB, and the association of SI and SSIB at any time point with child characteristics and internalizing and externalizing problems at age 7. SI occurred in 9.6% of children and was associated with fewer ASD symptoms and better adaptive functioning at age 7. SSIB occurred in 14.6% and was associated with poorer adaptive functioning and more externalizing behaviour at age 7. Internalizing problems were not associated with SI or SSIB at any time point. SI and SSIB rarely co-occurred (4%).

A growing body of research has examined the efficacy of varying formats (individual, group, linear, modular) of cognitive-behavioral therapy (CBT) as a treatment for anxiety disorders in children and youth with autism spectrum disorders (ASD). The present review utilized Chambless and Hollon's (1998) criteria for efficacious treatments to: (1) critically review the current evidence base for the efficacy of CBT for anxiety disorders in ASD; and (2) provide recommendations for future research. Findings identify two probably efficacious CBT programs (one group and one individual program) and five possibly efficacious programs, but no well-established programs. Similarities and differences in the components of these programs, which range from unmodified to specifically developed for ASD populations, are highlighted. In addition, the steps required to demonstrate well-established efficacy, and ultimately effectiveness, are discussed alongside other recommendations for refined future research.
