Cognitive enhancement therapy for adults with autism spectrum disorder: results of an 18-month feasibility study

Effects of multisession cathodal transcranial direct current stimulation with cognitive training on sociocognitive functioning and brain dynamics in autism: A double-blind, sham-controlled, randomized EEG study

BACKGROUND

Few treatment options are available for targeting core symptoms of autism spectrum disorder (ASD). The development of treatments that target common neural circuit dysfunctions caused by known genetic defects, namely, disruption of the excitation/inhibition (E/I) balance, is promising. Transcranial direct current stimulation (tDCS) is capable of modulating the E/I balance in healthy individuals, yet its clinical and neurobiological effects in ASD remain elusive.

OBJECTIVE

This double-blind, randomized, sham-controlled trial investigated the effects of multisession cathodal prefrontal tDCS coupled with online cognitive remediation on social functioning, information processing efficiency and the E/I balance in ASD patients aged 14-21 years.

METHODS

Sixty individuals were randomly assigned to receive either active or sham tDCS (10 sessions in total, 20 min/session, stimulation intensity: 1.5 mA, cathode: F3, anode: Fp2, size of electrodes: 25 cm2) combined with 20 min of online cognitive remediation. Social functioning, information processing efficiency during cognitive tasks, and theta- and gamma-band E/I balance were measured one day before and after the treatment.

RESULTS

Compared to sham tDCS, active cathodal tDCS was effective in enhancing overall social functioning [F(1, 58) = 6.79, p = .012, ηp2 = 0.105, 90% CI: (0.013, 0.234)] and information processing efficiency during cognitive tasks [F(1, 58) = 10.07, p = .002, ηp2 = 0.148, 90% CI: (0.034, 0.284)] in these individuals. Electroencephalography data showed that this cathodal tDCS protocol was effective in reducing the theta-band E/I ratio of the cortical midline structures [F(1, 58) = 4.65, p = .035, ηp2 = 0.074, 90% CI: (0.010, 0.150)] and that this reduction significantly predicted information processing efficiency enhancement (b = -2.546, 95% BCa CI: [-4.979, -0.113], p = .041).

CONCLUSION

Our results support the use of multisession cathodal tDCS over the left dorsolateral prefrontal cortex combined with online cognitive remediation for reducing the elevated theta-band E/I ratio in sociocognitive information processing circuits in ASD patients, resulting in more adaptive regulation of global brain dynamics that is associated with enhanced information processing efficiency after the intervention.

Enhancing pre-employment transition services: A type 1 hybrid randomized controlled trial protocol for evaluating WorkChat: A Virtual Workday among autistic transition-age youth

Autistic transition-age youth experience high rates of unemployment and underemployment, in part due to the social challenges they may face when having conversations in the workplace. In an effort to help enhance conversational abilities in the workplace, our collaborative team partnered to develop WorkChat: A Virtual Workday. Specifically, our team of scientists, community partners, and diversity and inclusion experts participated in a community-engaged process to develop WorkChat using iterative feedback from autistic transition-age youth and their teachers. With initial development complete, this study reports on the protocol that our collaborative team developed, reviewed, and approved to conduct a randomized controlled trial (RCT) to evaluate the real-world effectiveness and initial implementation process outcomes of WorkChat when integrated into post-secondary pre-employment transition services (Pre-ETS). Our aims are to: 1) evaluate whether services-as-usual in combination with WorkChat, compared to services-as-usual with an attention control, enhances social cognition and work-based social ability (between pre- and post-test); reduces anxiety about work-based social encounters (between pre- and post-test), and increases sustained employment by 9-month follow-up; 2) evaluate whether social cognitive ability and work-based social ability mediate the effect of WorkChat on sustained employment; and 3) conduct a multilevel, mixed-method process evaluation of WorkChat implementation.

Virtual Reality Training of Social Skills in Adults with Autism Spectrum Disorder: An Examination of Acceptability, Usability, User Experience, Social Skills, and Executive Functions

Poor social skills in autism spectrum disorder (ASD) are associated with reduced independence in daily life. Current interventions for improving the social skills of individuals with ASD fail to represent the complexity of real-life social settings and situations. Virtual reality (VR) may facilitate social skills training in social environments and situations similar to those in real life; however, more research is needed to elucidate aspects such as the acceptability, usability, and user experience of VR systems in ASD. Twenty-five participants with ASD attended a neuropsychological evaluation and three sessions of VR social skills training, which incorporated five social scenarios with three difficulty levels. Participants reported high acceptability, system usability, and user experience. Significant correlations were observed between performance in social scenarios, self-reports, and executive functions. Working memory and planning ability were significant predictors of the functionality level in ASD and the VR system's perceived usability, respectively. Yet, performance in social scenarios was the best predictor of usability, acceptability, and functionality level. Planning ability substantially predicted performance in social scenarios, suggesting an implication in social skills. Immersive VR social skills training in individuals with ASD appears to be an appropriate service, but an errorless approach that is adaptive to the individual's needs should be preferred.

Cognitive Coaching in Special Operations: Design Principles and Best Practices

Cognitive enhancement platforms have received growing interest as a means to improve workplace performance. Among the many commercial and professional organizations exploring cognitive training, the United States military has begun exploring the potential added value of cognitive enhancement tools. Whereas most platforms offer automated or algorithm-based solutions to support cognitive training, special operations have developed the role of a cognitive coach to support training. The current discussion provides several lessons learned when trying to bridge cognitive systems and enhancement tools within military operations that should apply to any organization seeking to improve cognitive performance among already high-performing personnel.

Group-based educational interventions in adolescents and young adults with ASD without ID: a systematic review focusing on the transition to adulthood

There is a growing number of young people, diagnosed with an autism-spectrum disorder (ASD), transitioning to adulthood. Among this number, individuals without an intellectual disability have significant adaptive deficits and need individualized care and support services to better target vocational, social, and educational prospects and outcomes. Group-based interventions, including patient education, social-skills training, and cognitive-behavioral therapy, are widely used in clinical settings to improve the daily life and prospects of ASD individuals facing the challenge of transitioning to adulthood. We performed a systematic review of studies concerning the efficiency of group-based educational interventions with a focus on the transition to adulthood for young, ASD individuals without intellectual disability (ID). As a result of this systematic search, 21 studies out of 163 were found to be eligible for inclusion. We observed considerable heterogeneity across the studies, in terms of effect sizes and intervention design, delivery, and the comparison of controls. Strong evidence was found in favor of social-skills training and cognitive-behavioral therapy interventions. Professionals should consider group-based psychoeducational intervention to be an appropriate and relevant service for young subjects with ASD without ID transitioning to adulthood. Further research is needed on larger samples using multicentric designs to validate efficacy before generalization.

Current Status of Evidence-Based Practices to Enhance Employment Outcomes for Transition Age Youth and Adults on the Autism Spectrum

PURPOSE OF REVIEW

This review provides a highlight of existing evidence-based practices and community support systems that exist to enhance employment outcomes for autistic transition-age youth (TAY) and adults. An update is provided on the current status of these programs and the impact they are having on employment outcomes for this population.

RECENT FINDINGS

Many programs exist that prove to be efficacious in improving employment outcomes. These programs can be categorized as vocational rehabilitation service system level interventions, provider and consumer level interventions targeting skills related to employment, and consumer level interventions delivered within community vocational rehabilitation or education settings. A more recent increase in programs is consistent with multiple research and policy calls for amplified programming in this area. Despite these recent increases, there is still a need to further develop effective programming to support employment outcomes as the growing autistic population age into adulthood. Community-based research and practice should continue to be developed and tested.

Cognitive deficits in children with autism spectrum disorders: Toward an integrative approach combining social and non-social cognition

Autism spectrum disorder (ASD) is associated with neurocognitive impairment, including executive dysfunctioning and social cognition (SC) deficits. Cognitive remediation (CR) is a behavioral training-based intervention aiming to improve cognitive processes. Its first use in psychiatry interested patients with schizophrenia, in whom promising results have been shown. Integrated CR programs targeting both social and non-social cognition have demonstrated to be effective in improving both cognitive domains and functional outcomes. CR studies in children and adolescents with ASD are still new, those regarding CR approaches combining social and executive functioning remediation are scares. One study examining the efficacy of cognitive enhancement therapy (CET) for improving cognitive abilities in ADS adults, showed significant differential increases in neurocognitive function and large social-cognitive improvements. Therefore, taking into account the overlap between ASD and schizophrenia, and considering the close link between executive functions (EF) and SC, we suggest that integrative approach in ASD could result in better outcomes. The present perspective aimed to highlight cognitive remediation (CR) programs contributions in ASD (especially in children and adolescents), and to discuss the value of combining social and non-social programs.

Is cognitive inflexibility a missing link? The role of cognitive inflexibility, alexithymia and intolerance of uncertainty in externalising and internalising behaviours in young people with autism spectrum disorder

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 externalising difficulties in ASD is essential for developing targeted supports and interventions. In the present study, we investigated established and less-researched cognitive factors hypothesised to contribute to internalising and/or externalising difficulties in ASD, namely cognitive inflexibility (CI), intolerance of uncertainty (IU) and alexithymia. Based on previous models and clinical experience, we hypothesised that IU would lead to internalising symptoms, with alexithymia contributing to this pathway, and that CI would have a direct effect on externalising behaviours and may indirectly contribute to internalising symptoms via increasing IU.

METHODS

Our sample consisted of 95 5- to 18-year-olds presenting to a specialist neurodevelopmental clinic and receiving a diagnosis of ASD. Parents/caregivers completed questionnaires assessing ASD symptomatology, internalising and externalising difficulties, CI, IU and alexithymia. Structural equation modelling was used to examine the hypothesised pathways and relationships between the main variables of interest.

RESULTS

Cognitive Inflexibility played a significant direct role in the pathway from ASD symptoms to externalising symptoms in ASD, and indirect role via IU in the pathway to internalising problems. Relationships between alexithymia and both internalising and externalising symptoms were weaker, with alexithymia predicting internalising difficulties via IU only.

CONCLUSIONS

The finding of a direct pathway from CI to externalising behaviours is novel, as is the indirect role of CI in internalising symptomatology. Of the three cognitive mechanisms examined, only CI significantly predicted externalising symptoms. Possible implications for interventions and supports targeting these cognitive processes in ASD are discussed.

An Intervention Program Targeting Daily Adaptive Skills Through Executive Function Training for Adults with Autism Spectrum Disorder: A Pilot Study

OBJECTIVE

Adults with autism spectrum disorders (ASD) experience significant difficulties with executive functioning (EF) and related adaptive skills, yet the lack of interventions in South Korea targeting these areas has resulted in a heightened need to develop an evidence- based program. Therefore, we developed a novel intervention aiming to enhance everyday EF and daily adaptive skills in adults with high-functioning ASD and conducted a pilot study to evaluate the validity and feasibility of the program.

METHODS

A behavioral intervention of 10-weekly sessions was developed based on literature searches and focus group interviews. Seven adults with high-functioning ASD (mean age=20.29) participated in a single-group pilot trial. We used self and parent-report questionnaires as well as skills measured by assessment instruments to analyze differences before and after the intervention.

RESULTS

Significant improvements were shown in everyday EF, including time management, organization, self-restraint, and regulation of emotions. Additionally, results demonstrated an enhancement in adaptive functioning, especially in the subdomains of daily living skills. Analyses of parental outcomes only revealed a significant decrease in the scores of emotion regulation.

CONCLUSION

The current study provides good evidence for the validity and feasibility of an intervention to improve everyday EF and adaptive skills in adults with ASD.

Non- Pharmacological Approaches on the Improvement of Sleep Disturbances in Patients with Autism Spectrum Disorder (ASD)

Abstract

Autism is a type of neurodegenerative disorder, caused by genetic and environmental factors. Children with autism spectrum disorder (ASD) have symptoms of attention deficit and behavioral problems. Child’s sleep pattern has a significant effect on mood. Sleep problems are more common in children with ASD. The current study aimed to investigate the effect of non-pharmacological approaches on the improvement of sleep disturbances in patients with ASD.

Materials & Methods

We systematically searched PubMed, EMBASE, Web of Science, Scopus, and Science Direct to identify relevant articles published from January 2009 to May 2019. All original articles from observational and interventional studies were reviewed. The CONSORT Statement and Strengthening the Reporting of Observational Studies in Epidemiology(STROBE) checklist were used to assess the quality of selected papers.

Results

Reviewing 18 eligible articles according to the CONSORT checklist(for interventional studies) and STROBE (for descriptive studies) demonstrated that behavioral interventions, such as cognitivebehavioral therapy, bedtime fading with response cost, and functional behavioral assessment, physical activity such as aerobic exercise, swimming, and aquatic exercise and weighted blankets can improve sleep disturbances.

Conclusion:

Restlessness, tantrums, increased stereotypic activities, and reduced

learning level and speaking power in children with autism were. caused by poor sleep quality and sleep deficiency, which may affect other dimensions of life. Non- pharmacological approaches to sleep disturbances could improve both sleep quality and quality of life of children with ASD with no adverse effect.

Profiling planning skills and cognitive flexibility of adults with autism spectrum disorders: Preliminary results from an exploratory service-based study

Background: Executive functions (EF) impairments have long been observed in children and youths with autism spectrum disorders (ASD). Until very recently, little attention has been paid to examine EF profiles of adults with ASD. Given the importance of EF to cope with the demands of daily life and participate in society (e.g. maintaining an employment), this study reports on a preliminary investigation aimed at exploring planning skills and cognitive flexibility in a sample of adults with ASD and without intellectual disability. A secondary aim was to explore the contribution of both intellectual functioning and socio-demographic variables on efficiency of EF. Method: Twenty-nine autistic adults (age range 18-50) were assessed using the Tower of London (ToL) test and the Wisconsin Card Sorting Test (WCST). Intellectual functioning was assessed with the Wechsler Adult Intelligence Scale - IV. Results: From the evaluations emerged poor performances in sub-processes related to planning skills as assessed by ToL (number of Moves, Correct Reponses, and Execution time). In contrast, WCST performance did not result impaired in any of the indicators considered. Exploratory analyses revealed a strong relationship between the time needed to complete the planning tasks and visuo-spatial reasoning. Further, strong inverse associations were found between global intellectual functioning and chronological age in the WCST. Conclusions: The results of this study highlight mixed EF profiles in a sample of adults with ASD. Future investigations may build on the results of the present study to understand whether evaluating planning abilities of adults with ASD by means of measures that do not require a time-limit would yield different results compared to time-constrained assessment procedures.

Adolescents With Autism Spectrum Disorder and Anorexia Nervosa Comorbidity: Common Features and Treatment Possibilities With Cognitive Remediation Therapy and Oxytocin

Autistic traits or autism spectrum disorder (ASD) can be found in 4% to 52% of anorexic patients, which makes the treatment of these patients very challenging. In this review, possible ways to treat ASD and anorexia nervosa (AN) comorbidity in children and adolescents are summarized. Over recent years, the focus has shifted from searching for the evidence of connections between these two disorders, which have started with Gillberg's study in 1983, to searching for more effective and holistic treatment of this comorbidity. The latter is known to contribute to more severe courses and worse prognosis, which is probably related to the obstacles in both diagnosing and treating. Since AN usually starts in early adolescence and high-functioning ASD children seem to begin struggling with increased pressure in adolescence, while various comorbidities can occur, it is important to improve the treatment of this comorbidity in young patients and to tailor it specifically in terms of diagnosing. In this paper, a literature review is conducted on common features and promising treatment possibilities. We describe cognitive remediation therapy and the promising pharmacotherapeutic candidate oxytocin with a special focus on adolescents.

Measuring change in facial emotion recognition in individuals with autism spectrum disorder: A systematic review

LAY ABSTRACT

Children and adults with autism spectrum disorder show difficulty recognizing facial emotions in others, which makes social interaction challenging. While there are many treatments developed to improve facial emotion recognition, there is no agreement on the best way to measure such abilities in individuals with autism spectrum disorder. The purpose of this review is to examine studies that were published between January 1998 and November 2019 and have measured change in facial emotion recognition to evaluate the effectiveness of different treatments. Our search yielded 65 studies, and within these studies, 36 different measures were used to evaluate facial emotion recognition in individuals with autism spectrum disorder. Only six of these measures, however, were used in different studies and by different investigators. In this review, we summarize the different measures and outcomes of the studies, in order to identify promising assessment tools and inform future research.

Defining Positive Outcomes in More and Less Cognitively Able Autistic Adults

Identifying positive outcomes for a wide range of intellectual abilities in autism spectrum disorder (ASD) remains a challenge. Several past studies of autistic adults have used outcome definitions that do not reflect the experiences of less cognitively able adults. The aim of the current study was to (1) define three domains of outcomes: autonomy, social relationships, and purpose, and (2) examine how these outcomes relate to concurrent aspects of adult functioning. Using data from a longitudinal sample of 126 adults (85% diagnosed with ASD at some point), mean age 26, who first entered the study in early childhood, we generated distinct outcomes for less (daily living skills above an 8-year-old level, having regular activities outside the home, and social contacts outside the family) and more cognitively able adults (living independently, having paid employment, and at least one true friend). Verbal IQ, assessed in adulthood, was a significant predictor of more outcomes achieved for individuals within more and less cognitively able groups. For less cognitively able adults, having ever received a formal ASD diagnosis (in contrast to current Autism Diagnostic Observation Schedule [ADOS] CSS scores) was associated with lower odds of positive outcomes. For more cognitively able adults, living skills and happiness measures were positively associated with number of outcomes met; higher ADOS CSS, internalizing and externalizing symptoms, being racially diverse, and having caregiver education below college graduation were all negatively associated with the number of positive outcomes. Tailoring outcomes to ability levels may lead to better identification of goals and service needs. LAY SUMMARY: This article describes the outcomes of autistic adults who are more and less cognitively able. For less cognitively able individuals, an earlier autism diagnosis was negatively related to outcomes. Several factors that were associated with positive outcomes for more cognitively able individuals, including daily living skills, fewer mental health problems, family demographics, and subjective measures of happiness. Our study identifies several important factors for families, individuals, and service providers to consider and discuss when planning the transition to adulthood.

Cognitive Remediation Interventions in Autism Spectrum Condition: A Systematic Review

BACKGROUND

Autism spectrum condition (ASC) is a lifelong neurodevelopmental condition characterized by difficulties in social cognition and heterogeneity of executive function which are suggested to be underpinned by neurobiological, prenatal and genetic factors. Cognitive remediation (CR) interventions are frequently used to address cognitive characteristics and improve cognitive and general functioning. However, the evidence is limited for ASC. This systematic review is the first to provide a narrative synthesis of all studies of CR interventions and ASC. The review aimed to delineate the development of research in this area in both adolescents and adults, with implications for clinical practice and future research.

METHOD

The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement. The literature was reviewed using the PubMed, PsycINFO, Web of Science, Scopus and Embase from inception to 1st April 2020. Out of 1,503 publications, a total of 13 papers were identified as being relevant for the review.

RESULTS

The 13 studies meeting the inclusion criteria were: four randomized control trials (RCTs); two non-randomized control trials, four case series, two feasibility studies and one case study. A narrative synthesis of the data suggested that CR interventions are potentially effective in improving social cognition and cognitive functioning in ASC. RCTs supported the efficacy of CR interventions in improving social cognition and executive functioning. Non-randomized control trials provided evidence for the effectiveness of social cognition remediation interventions in ASC. Case series and a case study have also supported the feasibility of CR interventions, including reflections on their adaptation for ASC populations and the positive feedback from participants.

CONCLUSIONS

CR interventions are potentially effective in improving social cognition and cognitive functioning in ASC. However, the generalizability of the included empirical studies was hampered by several methodological limitations. To further strengthen understandings of the effectiveness of CR interventions for ASC, future RCTs are needed with larger sample sizes in exploring the long-term effectiveness of CR interventions, using age-appropriate valid and reliable outcome measures. They should also consider the heterogeneity in neuropsychological functioning in ASC and the mediating and moderating mechanisms of the CR intervention for ASC.

Transdiagnostic validity of the MATRICS Consensus Cognitive Battery across the autism-schizophrenia spectrum

BACKGROUND

Autism Spectrum Disorder (ASD) and schizophrenia are neurodevelopmental disorders which share substantial overlap in cognitive deficits during adulthood. However, treatment evaluation in ASD and treatment comparisons across ASD and schizophrenia are limited by a dearth of empirical work establishing the validity of a standard cognitive battery across ASD and schizophrenia. Promisingly, the MATRICS Consensus Cognitive Battery (MCCB) has been validated in schizophrenia and encompasses cognitive domains that are impacted in ASD. Thus, this study aimed to establish MCCB's generalizability from schizophrenia to ASD.

METHODS

Community-residing adults with schizophrenia (N = 100) and ASD (N = 113) underwent MCCB assessment. Using multigroup confirmatory factor analysis, MCCB's transdiagnostic validity was evaluated by examining whether schizophrenia and ASD demonstrate the same configuration, magnitude, and directionality of relationships within and among measures and their underlying cognitive domains.

RESULTS

Across schizophrenia and ASD, the same subsets of MCCB measures inform three cognitive domains: processing speed, attention/working memory, and learning. Except for group means in category fluency, continuous performance, and spatial span, both groups show vastly comparable factor structures and characteristics.

CONCLUSIONS

To our knowledge, this study is the first to establish the validity of a standard cognitive battery in adults with ASD and furthermore the first to establish a cognitive battery's comparability across ASD and schizophrenia. Cognitive domain scores can be compared across new samples using weighted sums of MCCB scores resulting from this study. These findings highlight MCCB's applicability to ASD and support its utility for standardizing treatment evaluation of cognitive outcomes across the autism-schizophrenia spectrum.

Establishing a standard emotion processing battery for treatment evaluation in adults with autism spectrum disorder: Evidence supporting the Mayer-Salovey-Caruso Emotion Intelligence Test (MSCEIT)

Autism spectrum disorder (ASD) and schizophrenia are neurodevelopmental disorders which show markedly similar deficits in emotion processing, yet treatment evaluation in ASD and treatment comparisons across ASD and schizophrenia are constrained by a lack of empirical work validating a standard emotion processing battery across ASD and schizophrenia. Encouragingly, the Mayer-Salovey-Caruso Emotion Intelligence Test, version 2.0 (MSCEIT (Mayer et al., 2003) spans the range of emotion processing deficits in schizophrenia and ASD. This study therefore aimed to establish MSCEIT's factorial, measurement, and structural invariance in community-residing adults with schizophrenia (N = 103) and ASD (N = 113) using multigroup confirmatory factor analysis. Consistent with prior studies in normative populations, a two-factor structure comprised of emotional experiencing and emotional reasoning was supported in ASD and schizophrenia. Both groups operationalize MSCEIT measures similarly, with all measures except for Facilitation and Management showing comparability across groups. To our knowledge, this study is not only the first to establish the measurement and structural invariance of a standard emotion perception battery in adults with ASD, it is also the first to establish its comparability across ASD and schizophrenia. Ultimately, these findings underscore MSCEIT's utility for standardizing treatment evaluation of social cognitive outcomes across the autism-schizophrenia spectrum.

MYmind: a Concurrent Group-Based Mindfulness Intervention for Youth with Autism and Their Parents

Objectives

The current study evaluated the use of MYmind, a concurrent mindfulness program in which youth with autism and their parents simultaneously receive group specific mindfulness training. Youth with autism can experience emotional and behavioral challenges, which are associated with parental stress. Mindfulness-based programs are emerging as a promising support for these challenges, for both children and parents. While two studies have documented the use of concurrent parent-child programs, neither involve control conditions.

Methods

Using a within-subject repeated measures design with a baseline component, 23 parent-child dyads were assessed on mindfulness, mental health, and youth emotion regulation and autism symptoms. Participants also rated their perceived improvement on a social validity questionnaire.

Results

There was improvement in youth autism symptoms, emotion regulation, and adaptive skills, and in parent reports of their own mindfulness following the program. There was also some indication of a waitlist effect for parent mental health, but not for other outcome variables. Participant feedback was mainly positive.

Conclusions

MYmind has the potential to contribute to emotion regulation and adaptability in youth with autism, and mindfulness in parents, though more rigorous controlled trials are needed.

Psychosocial Interventions Targeting Social Functioning in Adults on the Autism Spectrum: a Literature Review

PURPOSE OF REVIEW

There is a perceived shortage of evidence-based treatment programs for adults on the autism spectrum. This article reviews the recent research literature on psychosocial/behavioral interventions targeting social functioning in autistic adults without intellectual disability.

RECENT FINDINGS

We identified only 41 peer-reviewed studies published from 1980 to 2017 that tested intervention programs focused on one or more of the behavioral components of social functioning (i.e., social motivation, social anxiety, social cognition, and social skills) in more than one adult with autism spectrum disorder (ASD). The studies demonstrated substantial variability in treatment objectives, intervention procedures, assessment methods, and methodologic quality. The results indicate a strong need for additional research to develop and rigorously test interventions for autistic adults that target the many behavioral components of social functioning and that include procedures to promote generalization of knowledge and skills to community settings.

Neuropsychological assessment in autism spectrum disorder and related conditions

Neuropsychological assessment provides a profound analysis of cognitive functioning in people with autism spectrum disorder (ASD). Individuals on the autistic spectrum often show a high level of anxiety and are frequently affected by comorbidities that influence their quality of life. Yet, they also have cognitive strengths that should be identified in order to develop effective support strategies. This article presents an overview of five cognitive areas that are essential for neuropsychological evaluation (ie, intelligence, attention, executive function, social cognition, and praxis) and explores the underlying causes of behavioral problems in persons with ASD. Furthermore, it stresses the importance of meticulous neuropsychological testing with regard to cognitive remediation, a method that can help to enhance single cognitive processes in a targeted manner. Objective test results suggest it might be possible to promote an improved sense of coherence. In line with the salutogenic model, this may be fundamental for human health and well-being.

Autism spectrum disorder and the science of social work: A grand challenge for social work research

The social work profession has not yet taken a leadership role in addressing the myriad of challenges that individuals on the autism spectrum encounter across the lifespan. In this essay, we argue that social workers are well equipped to engage in research and practice aimed at promoting full and meaningful inclusion in society, as well as social and economic justice, for individuals on the autism spectrum. We highlight short- and long-term goals that provide the social work profession with a framework to engage in research, practice, education, and advocacy aimed at supporting individuals on the autism spectrum and their families.

The combined impact of social support and perceived stress on quality of life in adults with autism spectrum disorder and without intellectual disability

Identifying modifiable correlates of good quality of life in adults with autism spectrum disorder is of paramount importance for intervention development as the population of adults with autism spectrum disorder increases. This study sought to examine social support and perceived stress as potential modifiable correlates of quality of life in adults with autism spectrum disorder. We hypothesized that adults with autism spectrum disorder without co-occurring intellectual disabilities ( N = 40; aged 18-44 years) would report lower levels of social support and quality of life than typical community volunteers who were matched for age, sex, and race ( N = 25). We additionally hypothesized that social support would buffer the effect of perceived stress on quality of life in adults with autism spectrum disorder. Results indicated that adults with autism spectrum disorder reported significantly lower levels of social support and quality of life than matched typical community volunteers. In addition, findings showed significant direct effects of social support and perceived stress on quality of life in adults with autism spectrum disorder. Social support did not buffer the effect of perceived stress on quality of life. Interventions that teach adults with autism spectrum disorder skills to help them better manage stress and cultivate supportive social relationships have the potential to improve quality of life.

Brief Report: Relationship Between ADOS-2, Module 4 Calibrated Severity Scores (CSS) and Social and Non-Social Standardized Assessment Measures in Adult Males with Autism Spectrum Disorder (ASD)

The ADOS-2 Modules 1-3 now include a standardized calibrated severity score (CSS) from 1 to 10 based on the overall total raw score. Subsequent research published CSS for Module 4 (Hus, Lord, Journal of Autism and Developmental Disorders 44(8):1996-2012, 2014); however more research is needed to examine the psychometric properties of this CSS. Forty males with ASD completed an assessment battery consisting of ADOS-2 Module 4 and other clinical measures assessing core ASD symptomology and comorbidity. Pearson correlation analyses found that CSS did not correlate with measures that assessed core social deficits of ASD or general psychiatric co-morbidity, but CSS did correlate negatively with intellectual quotient. These findings provide information on the limitations and relevance of CSS to be taken into account in future clinical evaluations of ASD.

Using Cognitive Neuroscience to Improve Mental Health Treatment: A Comprehensive Review

Mental health interventions do not yet offer complete, client-defined functional recovery, and novel directions in treatment research are needed to improve the efficacy of available interventions. One promising direction is the integration of social work and cognitive neuroscience methods, which provides new opportunities for clinical intervention research that will guide development of more effective mental health treatments that holistically attend to the biological, social, and environmental contributors to disability and recovery. This article reviews emerging trends in cognitive neuroscience and provides examples of how these advances can be used by social workers and allied professions to improve mental health treatment. We discuss neuroplasticity, which is the dynamic and malleable nature of the brain. We also review the use of risk and resiliency biomarkers and novel treatment targets based on neuroimaging findings to prevent disability, personalize treatment, and make interventions more targeted and effective. The potential of treatment research to contribute to neuroscience discoveries regarding brain change is considered from the experimental-medicine approach adopted by the National Institute of Mental Health. Finally, we provide resources and recommendations to facilitate the integration of cognitive neuroscience into mental health research in social work.

Cognitive enhancement therapy for adult autism spectrum disorder: Results of an 18-month randomized clinical trial

Cognitive remediation is a promising approach to treating core cognitive deficits in adults with autism, but rigorously controlled trials of comprehensive interventions that target both social and non-social cognition over a sufficient period of time to impact functioning are lacking. This study examined the efficacy of cognitive enhancement therapy (CET) for improving core cognitive and employment outcomes in adult autism. Verbal adult outpatients with autism spectrum disorder (N = 54) were randomized to an 18-month, single-blind trial of CET, a cognitive remediation approach that integrates computer-based neurocognitive training with group-based training in social cognition, or an active enriched supportive therapy (EST) comparison focused on psychoeducation and condition management. Primary outcomes were composite indexes of neurocognitive and social-cognitive change. Competitive employment was a secondary outcome. Intent-to-treat analyses indicated that CET produced significant differential increases in neurocognitive function relative to EST (d = .46, P = .013). Both CET and EST were associated with large social-cognitive improvements, with CET demonstrating an advantage at 9 (d = .58, P = 0.020), but not 18 months (d = .27, P = 0.298). Effects on employment indicated that participants treated with CET were significantly more likely to gain competitive employment than those in EST, OR = 6.21, P = 0.023, which was mediated by cognitive improvement. CET is a feasible and potentially effective treatment for core cognitive deficits in adult autism spectrum disorder. The treatment of cognitive impairments in this population can contribute to meaningful improvements in adult outcomes.

LAY SUMMARY

Cognitive enhancement therapy (CET), an 18-month cognitive remediation intervention designed to improve thinking and social understanding, was found to be more effective than supportive therapy at improving mental quickness, attention, and employment in adults living with autism. Social understanding was equally improved in CET and supportive therapy. Cognitive remediation interventions are feasible and may confer significant functional benefits to adults with autism.

Asperger Syndrome and Schizophrenia: A Comparative Neuropsychological Study

There has been an increasing interest in possible connections between autism spectrum disorder (ASD) and schizophrenia in the last decade. Neuropsychological comparison studies have, however, been few. The present study examined similarities and differences in intellectual and executive functioning between adults with Asperger syndrome (AS) and adults with schizophrenic psychosis (SP). A group with AS and a group with SP were assessed neuropsychologically with WAIS-III and D-KEFS. Similarities were found between groups, as displayed by an uneven cognitive profile, limitations in working memory, processing speed and some aspects of executive functioning. Full Scale IQ was higher in the AS group. These results add to the current research illuminating similarities and differences between ASD and schizophrenia on a cognitive level.

Feasibility of cognitive remediation therapy for adults with autism spectrum disorders: a single-group pilot study

BACKGROUND

Set-shifting (SS) difficulties and weak central coherence (CC) are commonly associated with autism spectrum disorders (ASD). Cognitive remediation therapy (CRT) aims to improve such cognitive processing; however, there are no reports on CRT for patients with ASD. This pilot study aimed to provide preliminary evidence to support the use of CRT for individuals with ASD and provide data to inform future studies.

PARTICIPANTS AND METHODS

Nineteen individuals with ASD were recruited and administered a series of neuropsychological and questionnaire measures to examine cognitive function and clinical outcomes such as anxiety and depression. Participants received CRT, and cognitive function and clinical variables were re-evaluated at postintervention and after 3 months.

RESULTS

The participants demonstrated significant improvement in CC and anxiety at postintervention, which was maintained at 3-month follow-up. Although SS scores had improved with a large effect size, this was not statistically significant.

CONCLUSION

CRT improved CC and anxiety scores for individuals with ASD, suggesting that CRT is an effective treatment for individuals with ASD.

Support for adults with autism spectrum disorder without intellectual impairment: Systematic review

Adults with autism spectrum disorder without intellectual impairment may benefit from a range of support services. This article presents the results of a systematic review assessing the effectiveness of supportive interventions for adults with autism spectrum disorder without intellectual impairment. A total of 32 studies were included; most focused on younger male participants. Although evidence was lacking for most types of intervention, employment programmes and social skills training were found to be effective for more proximal outcomes such as social skills. Evidence that any intervention improves mental health or well-being was very limited. Most interventions focused on mitigating specific deficits, rather than on providing broader support. Further research is needed on the effectiveness of supportive interventions such as advocacy and mentoring.

Effects of therapeutic recreation on adults with ASD and ID: a preliminary randomized control trial

BACKGROUND

The purpose of this research was to examine effects of a therapeutic recreation (TR) program designed to increase executive function (EF), social skills, adaptive behaviours and well-being of adults with autism spectrum disorder (ASD) and intellectual disability (ID).

METHOD

A preliminary pre-test, post-test randomized control group experimental design was used to measure effects of a 40-week TR program designed to increase EF (TR-EF). The TR-EF used instructional electronically based games delivered during 200 1-h sessions (5/week).

RESULTS

Participants (experimental group, n = 19; wait-list group, n = 18) were evaluated at baseline and 10 months later. There was a positive and direct impact of the program on several EF and indirect effect on social skills, adaptive behaviour and personal well-being.

CONCLUSIONS

Findings provide support for inclusion of EF enrichment as a way to enhance effects of TR interventions for adults with ASD and ID. Preliminary results of this study can be considered in planning TR services in the future. In addition to TR-EF program primary effects on EF, there were indirect benefits on adaptive behaviours, personal well-being and social skills.

Correlates of Social Functioning in Autism Spectrum Disorder: The Role of Social Cognition

BACKGROUND

Individuals with autism spectrum disorder (ASD) experience marked challenges with social function by definition, but few modifiable predictors of social functioning in ASD have been identified in extant research. This study hypothesized that deficits in social cognition and motor function may help to explain poor social functioning in individuals with ASD.

METHOD

Cross-sectional data from 108 individuals with ASD and without intellectual disability ages 9 through 27.5 were used to assess the relationship between social cognition and motor function, and social functioning.

RESULTS

Results of hierarchical multiple regression analyses revealed that greater social cognition, but not motor function, was significantly associated with better social functioning when controlling for sex, age, and intelligence quotient. Post-hoc analyses revealed that, better performance on second-order false belief tasks was associated with higher levels of socially adaptive behavior and lower levels of social problems.

CONCLUSIONS

Our findings support the development and testing of interventions that target social cognition in order to improve social functioning in individuals with ASD. Interventions that teach generalizable skills to help people with ASD better understand social situations and develop competency in advanced perspective taking have the potential to create more durable change because their effects can be applied to a wide and varied set of situations and not simply a prescribed set of rehearsed situations.

Schema therapy as treatment for adults with autism spectrum disorder and comorbid personality disorder: Protocol of a multiple-baseline case series study testing cognitive-behavioral and experiential interventions

Background

To our knowledge treatment of personality disorder (PD) comorbidity in adults with ASD is understudied and is still in its infancy. This study investigates the effectiveness of schema therapy for PD-psychopathology in adult patients with both ASD and PD.

Methods/design

Twelve adult individuals (age > 18 years) with ASD and at least one PD are given a treatment protocol consisting of 30 weekly offered sessions. A concurrent multiple baseline design is used with baseline varying from 4 to 9 weeks, after which weekly supportive sessions varying from 1 to 6 weeks start with the study therapist. After baseline and 1 to 6 supportive sessions, a 5-week exploration phase follows with weekly sessions during which current and past functioning, psychological symptoms, and schema modes are explored, and information about the treatment is given. This is followed by 15 weekly sessions with cognitive-behavioral interventions and 15 weekly sessions with experiential interventions: patients are vice versa and randomly assigned to the interventions. Finally, there is a 10-month follow-up phase with monthly booster sessions. Participants are randomly assigned to baseline length, and report weekly during treatment and monthly at follow-up on Belief Strength of negative core beliefs, and fill out SMI, SCL-90 and SRS-A 7 times during screening procedure (i.e. before baseline), after supportive sessions, after exploration, after cognitive and behavioral interventions, after experiential interventions, and after 5- and 10- month follow-up. The SCID-II is administered during screening procedure, at 5- and at 10-month follow-up.

Perception of Life as Stressful, Not Biological Response to Stress, is Associated with Greater Social Disability in Adults with Autism Spectrum Disorder

This study examined differences between adults with autism spectrum disorder (ASD; N = 40) and typical community volunteers (N = 25) on measures of stressful life events, perceived stress, and biological stress response (cardiovascular and cortisol reactivity) during a novel social stress task. Additional analyses examined the relationship between stress and social functioning as measured by the Social Adjustment Scale-II and the Waisman Activities of Daily Living scale. Results indicated that adults with ASD experienced significantly more stressful life events and perceived stress, and greater systolic blood pressure reactivity than typical community volunteers. Results also indicated that perceived stress and stressful life events were significantly associated with social disability. Interventions targeting stress management might improve social function in adults with ASD.

Sex-Related Cognitive Profile in Autism Spectrum Disorders Diagnosed Late in Life: Implications for the Female Autistic Phenotype

Females with high-functioning ASD are known to camouflage their autistic symptoms better than their male counterparts, making them prone to being under-ascertained and delayed in diagnostic assessment. Thus far the underlying cognitive processes that enable such successful socio-communicative adaptation are not well understood. The current results show sex-related differences in the cognitive profile of ASD individuals, which were diagnosed late in life exclusively. Higher verbal abilities were found in males (n = 69) as opposed to higher processing speed and better executive functions in females with ASD (n = 38). Since both sexes remained unidentified during childhood and adolescence, these results are suggestive for sex-distinctive cognitive strategies as an alternative to typically-developed reciprocal social behavior and social mimicry in high functioning ASD.

Autism spectrum disorder in adults: diagnosis, management, and health services development

Autism spectrum disorder (ASD) is a common neurodevelopmental disorder characterized by pervasive difficulties since early childhood across reciprocal social communication and restricted, repetitive interests and behaviors. Although early ASD research focused primarily on children, there is increasing recognition that ASD is a lifelong neurodevelopmental disorder. However, although health and education services for children with ASD are relatively well established, service provision for adults with ASD is in its infancy. There is a lack of health services research for adults with ASD, including identification of comorbid health difficulties, rigorous treatment trials (pharmacological and psychological), development of new pharmacotherapies, investigation of transition and aging across the lifespan, and consideration of sex differences and the views of people with ASD. This article reviews available evidence regarding the etiology, legislation, diagnosis, management, and service provision for adults with ASD and considers what is needed to support adults with ASD as they age. We conclude that health services research for adults with ASD is urgently warranted. In particular, research is required to better understand the needs of adults with ASD, including health, aging, service development, transition, treatment options across the lifespan, sex, and the views of people with ASD. Additionally, the outcomes of recent international legislative efforts to raise awareness of ASD and service provision for adults with ASD are to be determined. Future research is required to identify high-quality, evidence-based, and cost-effective models of care. Furthermore, future health services research is also required at the beginning and end of adulthood, including improved transition from youth to adult health care and increased understanding of aging and health in older adults with ASD.

Collection of developmental history in the evaluation of schizophrenia spectrum disorders

BACKGROUND

Schizophrenia is a heterogeneous disorder that is characterized by varying levels of hallucinations, delusions, negative symptoms, and disorganized features. The presence and severity of neurodevelopmental precursors and premorbid psychopathology also vary among individuals. To fully understand individual patients and to sort out phenotypic heterogeneity for genetic research studies, instruments designed to collect developmental history relevant to schizophrenia may be helpful.

OBJECTIVE

The goal was to describe a pair of self-report and parent-report instruments developed for the purpose of collecting the developmental history of patients with known or suspected schizophrenia spectrum disorders.

METHOD

Two developmental history instruments were designed for use in studies of brain morphology and cognition in schizophrenia probands and their unaffected siblings. The instruments focus mainly on motor abnormalities and other features that have been described as schizophrenia precursors.

RESULTS

The Motor Skills History Form is a brief self-report form that asks about patients' childhood and adolescent motor abilities as well as their current motor functioning. The Developmental & Motor History Form is a more detailed parent-rated form that covers aspects of patients' early (infant/preschool) development; their childhood and adolescent motor abilities; any childhood behaviors that may be related to later psychosis risk; and their history of any neurological, emotional, or cognitive disorders diagnosed during childhood or adolescence. The instruments can be used either for interviews or as self-administered questionnaires. The parent-rated form has been used for research and for the clinical assessment of children and adolescents with complex neurodevelopmental presentations with or without strong evidence of schizophrenia risk.

CONCLUSIONS

The collection of developmental history information is important when evaluating individuals with schizophrenia and related disorders. The Motor Skills History Form and the Developmental & Motor History Form can be used to collect this information for clinical evaluation or research purposes.

Independence of Hot and Cold Executive Function Deficits in High-Functioning Adults with Autism Spectrum Disorder

Individuals with autistic spectrum disorder (ASD) display diverse deficits in social, cognitive and behavioral functioning. To date, there has been mixed findings on the profile of executive function deficits for high-functioning adults (IQ > 70) with ASD. A conceptual distinction is commonly made between "cold" and "hot" executive functions. Cold executive functions refer to mechanistic higher-order cognitive operations (e.g., working memory), whereas hot executive functions entail cognitive abilities supported by emotional awareness and social perception (e.g., social cognition). This study aimed to determine the independence of deficits in hot and cold executive functions for high-functioning adults with ASD. Forty-two adults with ASD (64% male, aged 18-66 years) and 40 age and gender matched controls were administered The Awareness of Social Inference Test (TASIT; emotion recognition and social inference), Letter Number Sequencing (working memory) and Hayling Sentence Completion Test (response initiation and suppression). Between-group analyses identified that the ASD group performed significantly worse than matched controls on all measures of cold and hot executive functions (d = 0.54 - 1.5). Hierarchical multiple regression analyses revealed that the ASD sample performed more poorly on emotion recognition and social inference tasks than matched controls after controlling for cold executive functions and employment status. The findings also indicated that the ability to recognize emotions and make social inferences was supported by working memory and response initiation and suppression processes. Overall, this study supports the distinction between hot and cold executive function impairments for adults with ASD. Moreover, it advances understanding of higher-order impairments underlying social interaction difficulties for this population which, in turn, may assist with diagnosis and inform intervention programs.

Psychological interventions for adults with autism spectrum disorders: a review

Purpose

– Adults who have autism spectrum disorders (ASD) experience a range of core and co-morbid characteristics which impede daily functioning and quality of life. Children and adolescents with ASD derive clinically meaningful benefits from psychological interventions, including those designed to reduce socio-communication deficits and mental health conditions. Relatively little is known about the effectiveness of these interventions for the adult ASD population. The paper aims to discuss this issue.

Design/methodology/approach

– A selective search of English language, peer-reviewed publications was undertaken, in order to summarise the empirical data pertaining to psychological interventions for adults with high-functioning ASD (HF-ASD).

Findings

– Thus far, social skills interventions, cognitive behaviour therapy techniques, and mindfulness-based approaches have been researched most extensively. Interventions have primarily sought to: reduce the impact of core ASD characteristics; enhance skills; and improve co-morbid mental health symptoms. Methodological and clinical heterogeneity render it difficult to generalise study findings across population samples, but overall, interventions appear to be associated with reductions in co-morbid symptom severity, and improved functioning.

Research limitations/implications

– Further studies that seek to improve functioning, reduce co-morbid characteristics, and enhance the propensity for attaining and maintaining independence are now needed.

Practical implications

– Adaptations to standard treatment protocols are likely required in order to enhance engagement and optimise treatment gains.

Originality/value

– This is one of the first reviews to focus specifically on psychological interventions for adults with HF-ASD.

Social cognitive training in adolescents with chromosome 22q11.2 deletion syndrome: feasibility and preliminary effects of the intervention

BACKGROUND

Children with chromosome 22q11.2 deletion syndrome (22q11DS) often have deficits in social cognition and social skills that contribute to poor adaptive functioning. These deficits may be of relevance to the later occurrence of serious psychiatric illnesses such as schizophrenia. Yet, there are no evidence-based interventions to improve social cognitive functioning in children with 22q11DS.

METHODS

Using a customised social cognitive curriculum, we conducted a pilot small-group-based social cognitive training (SCT) programme in 13 adolescents with 22q11DS, relative to a control group of nine age- and gender-matched adolescents with 22q11DS.

RESULTS

We found the SCT programme to be feasible, with high rates of compliance and satisfaction on the part of the participants and their families. Our preliminary analyses indicated that the intervention group showed significant improvements in an overall social cognitive composite index.

CONCLUSIONS

SCT in a small-group format for adolescents with 22q11DS is feasible and results in gains in social cognition. A larger randomised controlled trial would permit assessment of efficacy of this promising novel intervention.

Further understanding of complex information processing in verbal adolescents and adults with autism spectrum disorders

More than 20 years ago, Minshew and colleagues proposed the Complex Information Processing model of autism in which the impairment is characterized as a generalized deficit involving multiple modalities and cognitive domains that depend on distributed cortical systems responsible for higher order abilities. Subsequent behavioral work revealed a related dissociation between concept formation and concept identification in autism suggesting the lack of an underlying organizational structure to manage increases in processing loads. The results of a recent study supported the impact of this relative weakness in conceptual reasoning on adaptive functioning in children and adults with autism. In this study, we provide further evidence of the difficulty relatively able older adolescents and adults with autism have with conceptual reasoning and provide evidence that this characterizes their difference from age- and ability-matched controls with typical development better than their differences in language. For verbal adults with autism, language may serve as a bootstrap or compensatory mechanism for learning but cannot overcome an inherent weakness in concept formation that makes information processing challenging as task demands increase.

Cognitive remediation in anorexia nervosa and related conditions: a systematic review

Research evidence for cognitive remediation therapy's (CRT) effectiveness for anorexia nervosa (AN) has been gathering. This approach is also increasingly being implemented in other disorders including major depressive disorder, obsessive-compulsive disorder and autistic spectrum disorder that share commonalities with AN in neuropsychological profiles and clinical presentations. This systematic literature review identified and appraised the current evidence base to see whether evidence from related conditions could be integrated into the theoretical understanding of CRT for AN as well as future AN treatment developments and research. Overall, CRT studies in AN report promising findings, and CRT appears to be associated with improvements in set-shifting and in central coherence. Cognitive remediation approaches in other conditions also show promising evidence in associated improvements in areas of executive functioning and information processing; links are made between AN treatment and what future treatment developments could consider.

Cognitive training in mental disorders: update and future directions

OBJECTIVE

This article reviews the conceptual basis, definitions, and evolution of cognitive training approaches for the treatment of mental disorders.

METHOD

The authors review the current state of the knowledge on cognitive training in psychiatric illnesses, and its neural and behavioral targets, and summarize the factors that appear to relate to a successful response, including learner characteristics that influence clinical outcome. They also discuss methodological issues relevant to the development and testing of cognitive training approaches, with the goal of creating maximally efficient and effective approaches to training. Finally, they identify gaps in existing knowledge and outline key research directions for the future.

RESULTS

While much of the early research has been conducted in schizophrenia, cognitive training has more recently been applied to a widening range of neuropsychiatric illnesses, including attention deficit hyperactivity disorder, mood disorders, and substance use disorders. Cognitive training harnesses the inherent neuroplastic capacities of the brain, targeting neural system function across psychiatric disorders, thus improving the cognitive processes that play a role in emotion regulation, clinical symptoms, and adaptive community functioning.

CONCLUSIONS

Cognitive training offers considerable promise, especially given the limited efficacy of pharmacological interventions in ameliorating cognitive deficits. However, more research is needed to understand the mechanisms underlying cognitive training, predictors of response, generalization and real-world applicability, and approaches to dissemination in practice settings.

Commonalities in social and non-social cognitive impairments in adults with autism spectrum disorder and schizophrenia

Autism spectrum disorder (ASD) and schizophrenia are both conditions that are characterized by impairments in social and non-social cognition, yet commonalities in the magnitude and domains of cognitive deficits across these two conditions remain unclear. This study examined neurocognitive and social-cognitive functioning in 47 outpatients with schizophrenia, 43 verbal adults with ASD, and 24 healthy volunteers. A comprehensive neuropsychological battery assessing processing speed, attention, memory, and problem-solving domains was administered along with a social-cognitive battery of emotion processing. Results demonstrated large and significant impairments in emotion processing and neurocognition relative to healthy individuals in participants with autism (d=-.97 and -1.71, respectively) and schizophrenia (d=-.65 and -1.48, respectively). No significant differences were observed between those with ASD and schizophrenia on any cognitive domain assessed, and the areas of greatest impairment were identical across both disorders and included slowness in speed of processing and an inability to understand emotions. These findings indicate a high degree of similarity in the cognitive challenges experienced by verbal adults with autism and schizophrenia, and the potential need for trans-diagnostic remediation approaches to enhance cognition in these conditions.
