Psychiatric comorbidities in asperger syndrome and high functioning autism: diagnostic challenges

The Reliability and Validity of the Korean Version of Autism Spectrum Quotient (AQ) Children's Version

There is no validated screening measure for children with high-functioning autism spectrum disorder (ASD) in Korea. The purpose of the present study was (1) to examine the reliability and validity of the Korean version of the Autism Spectrum-Child (K-AQ-Child); (2) to find the optimal cut-off value of the K- AQ-Child in the Korean population. A total of 144 children aged 4-11 years (male 80.6%, mean age = 7.05 ± 1.75) were recruited in this study, with 72 in the high-functioning ASD group and 72 in the non-clinical Control group. The Cronbach's alpha coefficient of the K-AQ-child was 0.962, showing excellent internal consistency. For discriminant validity, the ASD group scored significantly higher than the Control group on the total score and all the scores of the subdomains of the K-AQ-Child after controlling for sex. Significant positive correlation between total scores of the K-AQ-Child and the K-SCQ was found. The optimal cut-off value of 58.5 yielded a sensitivity of 0.931 and specificity of 0.986. K-AQ-Child is a valid and reliable measure to quantify autistic traits and identify the high-risk individuals for further diagnostic evaluation in intellectually capable children aged 4-11 years. It would be useful for both clinical practice and research purposes. Clinical Trial Registration The trial was registered at the Clinical Research Information Service (CRIS) of Republic of Korea (Registration Number: KCT0008907).

Using Restricted Interests in Cognitive Behavioral Therapy for Children With Autism Spectrum Disorder: Results From a Preliminary Randomized Controlled Trial

Children with autism spectrum disorder (ASD) exhibit significant deficits in social communication and emotion regulation skills. While cognitive behavioral therapy (CBT) applications appear promising, trials to date have largely excluded social communication skill development and have not been designed to include a wider range of emotional challenges. To our knowledge, the present study is the first to pilot a uniquely modified CBT program targeting emotion regulation, including social communication training, and explicitly focusing on the child's areas of circumscribed interest in order to teach skills and promote generalization. Forty participants were randomly assigned to either the CBT group or a waitlist control (WLC) group, resulting in 20 school-aged children in each group. The treatment approach was determined to be feasible and acceptable, and therapy engagement and attendance were reasonably high. Caregivers expressed high satisfaction with the program, qualitatively citing gains in skills such as social problem-solving, emotion identification, and identifying and processing cognitive distortions. The primary outcome of postintervention changes was not significantly different between the groups (CBT vs. WLC). The mean Social Skills Improvement System score decreased by 0.44 points (95% confidence interval [CI]: -5.04, 4.15) in the CBT group and increased by 0.41 points (95% CI: -4.23, 5.04) in the WLC group, and the postintervention changes were not significantly different between the groups (difference: -0.85; 95% CI: -7.29, 5.60; p = .79). The estimated rate of emotional dysregulation episodes decreased by a factor of 0.94 (95% CI: 0.57, 1.56) in the CBT group and increased by a factor of 1.07 (95% CI: 0.51, 2.24) for WLC (p = .74). Among those who reported emotional dysregulation episodes, the mean duration decreased by 1.39 minutes (95% CI: -3.90, 6.67) less for CBT than waitlist (p = .60). Although satisfaction, acceptability, and emotional dysregulation outcome results from this preliminary CBT treatment for ASD are promising, sample size and measurement limitations will be important considerations to inform future trials.

Contribution of the serotonergic system to developmental brain abnormalities in autism spectrum disorder

This review highlights a key role of the serotonergic system in brain development and in distortions of normal brain development in early stages of fetal life resulting in cascades of abnormalities, including defects of neurogenesis, neuronal migration, neuronal growth, differentiation, and arborization, as well as defective neuronal circuit formation in the cortex, subcortical structures, brainstem, and cerebellum of autistic subjects. In autism, defects in regulation of neuronal growth are the most frequent and ubiquitous developmental changes associated with impaired neuron differentiation, smaller size, distorted shape, loss of spatial orientation, and distortion of cortex organization. Common developmental defects of the brain in autism include multiregional focal dysplastic changes contributing to local neuronal circuit distortion, epileptogenic activity, and epilepsy. There is a discrepancy between more than 500 reports demonstrating the contribution of the serotonergic system to autism's behavioral anomalies, highlighted by lack of studies of autistic subjects' brainstem raphe nuclei, the center of brain serotonergic innervation, and of the contribution of the serotonergic system to the diagnostic features of autism spectrum disorder (ASD). Discovery of severe fetal brainstem auditory system neuronal deficits and other anomalies leading to a spectrum of hearing deficits contributing to a cascade of behavioral alterations, including deficits of social and verbal communication in individuals with autism, is another argument to intensify postmortem studies of the type and topography of, and the severity of developmental defects in raphe nuclei and their contribution to abnormal brain development and to the broad spectrum of functional deficits and comorbid conditions in ASD.

The impact of depressive and anxious symptoms on quality of life in adults on the autism spectrum

Quality of life (QoL) is lower in adults on the autism spectrum (AS) compared with typically developing (TD) adults. In this context, recent studies have examined the role of depression and anxiety in reducing QoL in AS adults. The aim of this study was to (1) replicate these findings of lower QoL and (2) assess the negative influence of depressive and anxious symptoms on QoL in an adult AS (N = 86) and TD (N = 87) German sample with a broad age range (18-70 years). For this, we used questionnaires that have been validated for the AS and TD population: the World Health Organization Quality of Life Brief Version, the Autism-Specific QoL items, and the Hospital Anxiety and Depression Scale. We replicated previous findings and extended them to autism-specific QoL. Our AS sample had lower QoL compared with the TD adults. However, depressive symptoms were the largest contributor to lower QoL in both samples, more so than group membership and anxious symptoms. We conclude that interventions to improve QoL in AS adults should specifically target depressive symptoms and for this, improvements to the diagnostic process and treatment of depression in AS are necessary.

Investigating the Structure of the CESD-R and DASS-21 Across Adults with Low and High Levels of Autistic Traits

The current study examined factorial invariance of the Center for Epidemiologic Studies Depression Scale-Revised (CESD-R) and the Depression Anxiety Stress Scales-21 (DASS-21) using a convenience sample of 434 adults surveyed though Amazon Mechanical Turk. Participants were sorted into two groups based on their score on the Autism-Spectrum Quotient. Results indicated that the CESD-R did not demonstrate configural invariance. The DASS-21 demonstrated evidence of scalar invariance, indicating cross-group equality in factor loadings and factor intercepts. Findings suggest that the DASS-21 measures symptoms of depression, anxiety, and stress consistently across individuals with high and low levels of ASD-related traits, whereas the CESD-R may not be valid when assessing symptoms of depression in those with a high level of ASD-related traits.

Resting Heart Rate Variability and Emotion Dysregulation in Adolescents with Autism Spectrum Disorder

Emotion dysregulation is common among individuals with autism spectrum disorder (ASD). This study examined the relationship between emotion dysregulation and resting heart rate variability (HRV), a marker of the autonomic nervous system, in ASD adolescents. Resting HRV data were collected from ASD (n = 23) and typically developing (TD) adolescents (n = 32) via short-term electrocardiogram. Parents/caregivers reported participants' level of emotion dysregulation with the Emotion Dysregulation Inventory (EDI). Controlling for the effects of age and gender, regression analyses revealed moderating effects of group, suggesting that lower resting HRV was more strongly associated with greater emotion dysregulation in ASD than TD adolescents. The results support the view that disruptions in autonomic functioning may contribute to emotion dysregulation in ASD.

Autistic Traits as Predictors of Increased Obsessive-Compulsive Disorder Severity: The Role of Inflexibility and Communication Impairment

Due to similar manifestations, some authors have proposed a potential correlation between autism spectrum disorder (ASD) and obsessive-compulsive disorder (OCD). This link has long been recognized and debated, with some authors arguing that these disorders frequently occur comorbid but distinct while others believe they are part of the same spectrum. The aim of our study was to explore the prevalence and correlates of autistic traits in 55 OCD patients and 55 matched controls and to assess possible autistic dimensions predictive of higher OCD symptoms. All participants were assessed with the Obsessive-Compulsive Spectrum-Short Version (OBS-SV) and the Adult Autism Subthreshold Spectrum (AdAS Spectrum). The OCD group scored significantly higher in both questionnaires. Total OBS-SV scores and domains were significantly correlated with all AdAS Spectrum domains and total score. The AdAS Spectrum total, Verbal Communication and Inflexibility and adherence to routine domain scores were significant positive predictors of higher OBS-SV scores. Lastly, when two clusters of subjects (high and low autism) were determined, Inflexibility and adherence to routine domain presented the greatest influence in forming the clusters. Our findings support the association between OCD and autistic traits in the adult population, supporting the hypothesis of a neurodevelopmental basis for these psychiatric conditions.

The Prevalence of Attention Deficit/Hyperactivity Disorder Symptoms in Children and Adolescents With Autism Spectrum Disorder Without Intellectual Disability: A Systematic Review

OBJECTIVE

ADHD commonly co-occurs with ASD without ID in young people. It has been difficult to obtain accurate prevalence estimates of ADHD in this population, as a dual-diagnosis was not permitted until DSM-V. We systematically reviewed the literature on the prevalence of ADHD symptoms in young people with ASD without ID.

METHOD

9,050 articles were identified through six databases. Articles were reviewed against inclusion and exclusion criteria and 23 studies were included.

RESULTS

ADHD symptom prevalence varied from 2.6% to 95.5%. We discuss these findings according to the ADHD assessment measure, informant, diagnostic criteria, risk of bias rating and recruitment pool.

CONCLUSION

ADHD symptoms are common in young people with ASD without ID, but there is substantial variance in study reporting. Future studies should recruit participants from community sources, provide information on key sociodemographic sample characteristics and assess ADHD with standardized diagnostic criteria, using both parent/carer and teacher report.

Autistic Traits and College Adjustment

This study evaluated the association of autistic traits (RAADS-14) with academic and social outcomes among college students using data from an online survey (N = 2,736). In the academic domain, the total trait score and all subscale scores (mentalizing deficits, social anxiety, sensory reactivity) were associated with course failure and academic difficulties independent of an autism diagnosis; the total score and mentalizing deficits also predicted lower grade point average (GPA). In the social domain, the total trait score and subscale scores were associated with lower odds of having a confidant, lower friendship quality, and higher odds of social exclusion. Subgroup analyses revealed that autistic traits had more consistently negative associations with social outcomes for students without an autism diagnosis than for students with a diagnosis. Associations were also more often significant for women than men. These results support the development of programs and services for students with autistic traits regardless of diagnostic status.

Autism spectrum disorder and congenital heart disease: a narrative review of the literature

Individuals born with congenital heart disease (CHD) are at an increased risk of developing neurodevelopmental disorders. Despite this, studies are limited in their investigation of autism spectrum disorder in the context of CHD. This review provides an overview of the literature examining autism spectrum disorder in CHD and discusses strengths, limitations, and future directions. Recent efforts have been made to extrapolate the association between CHD and symptoms of autism. Findings suggest that the core features of autism spectrum disorder are also implicated in children with CHD, namely social-cognitive weaknesses, pragmatic language differences, and social problems. Compared to norm-referenced samples, separate studies have identified divergent and overlapping neuropsychological profiles among both patient groups, yet there are no studies directly comparing the two groups. There is emerging evidence of prevalence rates of autism diagnosis in CHD showing an increased odds of having autism spectrum disorder among children with CHD relative to the general population or matched controls. There also appears to be genetic links to this overlap, with several genes identified as being tied to both CHD and autism. Together, research points to potentially shared underlying mechanisms contributing to the pathophysiology of neurodevelopmental, neuropsychological, and clinical traits in CHD and autism spectrum disorder. Future investigation delineating profiles across these patient populations can fill a significant gap in the literature and aid in treatment approaches to improve clinical outcomes.

Regulating Together: Emotion Dysregulation Group Treatment for ASD Youth and Their Caregivers

Individuals with autism spectrum disorder (ASD) experience behavioral and emotional symptoms hypothesized to arise from emotion dysregulation (ED), difficulty modulating emotional experience, expression, and intensity in an acceptable and contextually appropriate manner. We developed Regulating Together (RT)-an intensive-outpatient, caregiver-assisted group program to meet the ASD + ED intervention critical need. A within-subjects trial was conducted (5-week-control lead-in period, 5-week-treatment, and 5-and 10-weeks-post-treatment follow-ups). Forty-four youth with ASD + ED (25 8-12, 19 13-18 yr-olds, 88% male, mean FSIQ of 96) participated. Improvements were found in reactivity, emotion regulation knowledge, and flexibility post-treatment and 10-weeks post-treatment. A reduction in inpatient hospitalization rates by 16% from the 12 months pre-RT to 12 months post-RT was observed. RT shows promise to reduce ED in ASD.

Relationships between alexithymia, interoception, and emotional empathy in autism spectrum disorder

LAY ABSTRACT

Empathy, the ability to understand and share the emotions of others, is a necessary skill for social functioning and can be categorized into cognitive and emotional empathy. There is evidence to suggest that individuals with autism spectrum disorder have difficulties with cognitive empathy, the ability to imagine how another person is thinking or feeling. However, it is unclear if individuals with autism spectrum disorder struggle with emotional empathy, the ability to share and feel emotions others are experiencing. Self-report and interview data were collected to explore the relationships between interoception (individuals' self-reported awareness of sensation from their body such as thirst, heartbeat, etc.), alexithymia (an individual's ability to describe and distinguish between their own emotions), and emotional empathy in 35 youth with autism spectrum disorder and 40 typically developing youth. Greater personal distress to others' emotions and greater difficulty describing and recognizing self-emotions were associated with reporting fewer physical sensations in the body when experiencing emotion in the autism spectrum disorder group. The results of this study suggest that while autism spectrum disorder youth with concomitant alexithymia may experience emotional empathy differently, it should not be characterized as an absence of a capacity for emotional empathy.

“I Always Knew I Was Different”: Experiences of Receiving a Diagnosis of Autistic Spectrum Disorder in Adulthood—a Meta-Ethnographic Systematic Review

A broadening of diagnostic criteria and increased awareness of autism has led to a large number of individuals whose difficulties remained undetected until adulthood. This systematic review aimed to synthesise empirical evidence of the experience of individuals who received their diagnosis of autism in adulthood. Eight studies met the inclusion criteria. A meta-ethnographic approach was used to synthesise the findings. Analysis revealed two meta-themes: feeling “like an alien” and the “not guilty” verdict, each with three associated subthemes. The findings indicate the need for timely diagnosis and provision of post-diagnostic support to alleviate the mental health implications of not having a framework to understand one’s experiences and to support the process of adjustment to the diagnosis.

The relationship between alexithymia, interoception, and neural functional connectivity during facial expression processing in autism spectrum disorder

Neural processing differences of emotional facial expressions, while common in autism spectrum disorder (ASD), may be related to co-occurring alexithymia and interoceptive processing differences rather than autism per se. Here, we investigate relationships between alexithymia, interoceptive awareness of emotions, and functional connectivity during observation of facial expressions in youth (aged 8-17) with ASD (n = 28) compared to typically developing peers (TD; n = 37). Behaviorally, we found no significant differences between ASD and TD groups in interoceptive awareness of emotions, though alexithymia severity was significantly higher in the ASD group. In the ASD group, increased alexithymia was significantly correlated with lower interoceptive sensation felt during emotion. Using psycho-physiological interaction (PPI) analysis, the ASD group showed higher functional connectivity between the left ventral anterior insula and the left lateral prefrontal cortex than the TD group when viewing facial expressions. Further, alexithymia was associated with reduced left anterior insula-right precuneus connectivity and reduced right dorsal anterior insula-left ventral anterior insula connectivity when viewing facial expressions. In the ASD group, the degree of interoceptive sensation felt during emotion was positively correlated with left ventral anterior insula-right IFG connectivity when viewing facial expressions. However, across all participants, neither alexithymia nor interoceptive awareness of emotions predicted connectivity between emotion-related brain regions when viewing emotional facial expressions. To summarize, we found that in ASD compared to TD: 1) there is stronger connectivity between the insula and lateral prefrontal cortex; and 2) differences in interhemispheric and within left hemisphere connectivity between the insula and other emotion-related brain regions are related to individual differences in interoceptive processing and alexithymia. These results highlight complex relationships between alexithymia, interoception, and brain processing in ASD.

Depressive symptoms in workers with high autistic trait scores according to job stress type

Individuals with high levels of autistic traits are at a high risk of experiencing depressive symptoms, and are also vulnerable to job stress. This study aimed to identify which combination of autistic traits and type of job stress are related to depressive symptoms. Participants comprised 992 workers from different regions of Japan. Autistic traits, depressive symptoms, and job stress were measured using the Autism-Spectrum Quotient, K6 scale, and Job Content Questionnaire, respectively. Logistic regression was performed to estimate the odds ratio and 95% confidence interval. Workers with high autistic traits scores reported significantly more depressive symptoms for all job stress types, especially high job demand. Depressive symptoms differed according to autistic traits and job stress. In workers with high autistic trait subscale scores, those with active job stress reported more depressive symptoms than those with high strain job stress, except for the "poor imagination" trait. This is contrary to previous reports that the active stress type is generally less associated with depressive symptoms than the high-strain stress type. To prevent depressive symptoms in workers with high autistic trait scores, it is important to understand which combination of autistic traits and type of job stress contribute to depressive symptoms.

Adaptive behavior and psychiatric symptoms in university students with ASD: One-year longitudinal study

In recent years, more young adults with ASD are attending post-secondary education, and several support programs have been proposed for this population. However, research regarding the long-term effects of university enrollment on outcomes among students with ASD is scarce. This study examined adaptive behavior and psychiatric symptoms during the first semester of two consecutive academic years (T1, T2) among 39 students with ASD, 29 students without ASD and high levels of social anxiety symptoms (High SA), and 32 students without ASD and low levels of SA symptoms (Low SA). Students with ASD participated in a university support program and resided with a peer mentor student without ASD, which encouraged social interaction. At T1, students with ASD reported lower levels of adaptive behavior and higher levels of social anxiety and obsessive-compulsive symptoms compared to the other groups. However, at follow-up (T2), significantly higher conceptual adaptive skill levels (specifically communication skills) and significantly lower depression symptom levels from T1 were reported only among students with ASD. The levels of social anxiety and obsessive-compulsive symptoms at T1 were negatively associated with adaptive functioning a year later (T2). Implications regarding adults with ASD attending university are discussed.

The Early Childhood Signs of Autism in Females: a Systematic Review

Compared to males, females are at a much greater likelihood of receiving a later diagnosis of autism, which impacts their opportunity to receive early support. To assist with early identification, this systematic literature review aimed to ascertain whether females differ from males in the early childhood signs of autism. The small number of heterogeneous studies made it difficult to draw conclusions, although it appears that females and males under 6 years of age are more similar than different in terms of their expression of autistic behaviours. Given the discrepant sex/gender ratio in autism, these findings highlight the importance of exploring whether there are different and/or specific, not yet identified, early signs of autism in females and males.

The utility of the autism-spectrum quotient to screen for autism spectrum disorder in adults with attention deficit/hyperactivity disorder

The co-occurrence of attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) has been reported to be highly prevalent in adults. However, very few studies have assessed the usefulness of screening instruments to detect this co-occurrence, particularly when screening for ASD in the context of ADHD. Our study aimed at assessing the utility of the autism-spectrum quotient (AQ) as a screening tool of ASD in a sample of 153 adults referred for ADHD assessment. Our results showed that the AQ is of limited use in this context as its positive predictive value was low (47%). Particularly, the more severe the attentional deficits the more likely individuals with ADHD were to be misclassified as having a co-occurring ASD based on the AQ. However, the "imagination" subscale of the AQ was able to discriminate those who met ASD criteria from those who did not, suggesting that targeting imagination impairments might be useful when assessing for the ADHD+ASD co-occurrence in clinical settings.

Unity Assumption in Audiovisual Emotion Perception

We experience various sensory stimuli every day. How does this integration occur? What are the inherent mechanisms in this integration? The “unity assumption” proposes a perceiver’s belief of unity in individual unisensory information to modulate the degree of multisensory integration. However, this has yet to be verified or quantified in the context of semantic emotion integration. In the present study, we investigate the ability of subjects to judge the intensities and degrees of similarity in faces and voices of two emotions (angry and happy). We found more similar stimulus intensities to be associated with stronger likelihoods of the face and voice being integrated. More interestingly, multisensory integration in emotion perception was observed to follow a Gaussian distribution as a function of the emotion intensity difference between the face and voice—the optimal cut-off at about 2.50 points difference on a 7-point Likert scale. This provides a quantitative estimation of the multisensory integration function in audio-visual semantic emotion perception with regards to stimulus intensity. Moreover, to investigate the variation of multisensory integration across the population, we examined the effects of personality and autistic traits of participants. Here, we found no correlation of autistic traits with unisensory processing in a nonclinical population. Our findings shed light on the current understanding of multisensory integration mechanisms.

Trait Anxiety in Individuals on the Autism Spectrum: a Systematic Review

Although anxiety is commonly researched in autism, the focus has predominantly been on anxiety disorders and not upon general levels of anxiousness or trait anxiety. This review summarises research investigating trait anxiety in autism. Systematic searches yielded 1099 records, with 23 studies meeting inclusion criteria. Study participants were mainly males from Western countries, with no representation of older adults or individuals with intellectual disability. All articles used self-report questionnaire trait anxiety measures. Anxiety measure psychometric details were absent in most studies, with 21 using subjective measures that are not validated for use in autism. Results showed higher trait anxiety scores in autism versus control groups, and correlations between trait anxiety scores and other study outcomes.

Evidence from Characteristics and Comorbidities Suggesting That Asperger Syndrome Is a Subtype of Autism Spectrum Disorder

The current version of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM-V) does not consider Asperger syndrome a diagnostic category. This study was undertaken to see if there is evidence that this diagnosis should be reinstated. An online survey was conducted to examine symptoms and behaviors associated with the current diagnostic criteria of autism spectrum disorders (ASD) (DSM-V), and those associated with Asperger syndrome based on the previous version (DSM-IV-TR). The study also examined other characteristics historically associated with autism, as well as impairments often reported in infancy/young childhood and medical comorbidities frequently associated with autism. The sample included 251 individuals who had received a diagnosis of Asperger syndrome and 1888 who were diagnosed with autism or ASD. Numerous similarities and differences were found between the two groups. The findings are discussed in relation to reestablishing Asperger syndrome as a valid diagnostic category as well as a subtype of ASD.

A paradoxical psychological impact of COVID-19 among a sample of Italian adults with High Functioning Autism Spectrum Disorder

Background

Since February 2020, many governments of the world ordered strict social distancing rules to try to contain the COVID-19 pandemic, with a reported consequent increase in levels of stress, anxiety and depression in the general population. Aim of this study was to assess the prevalence of the aforementioned psychiatric symptoms across a sample of individuals with High Functioning Autism Spectrum Disorders (HF-ASDs) with respect to a group of neurotypical adults (NA), during the first two months of COVID-19 pandemic in Italy.

Method

45 adults with HF-ASDs and 45NA completed a structured online questionnaire, including; the Depression, Anxiety and Stress Scale – 21 items (DASS-21); the Impact of Event Scale-Revised (IES-R); the Perceived Stress Scale (PSS). We also explored some specific aspects of participants’ psychological well-being through an ad-hoc questionnaire.

Results

Subjects with HF-ASDs scored significantly higher than NA at the DASS-21, the IES-R Total Score and the PSS; NA reported a higher perceived change of their lifestyle during the lockdown than individuals with HF-ASDs, and subjects with HF-ASDs reported to feel more comfortable and less tired during the lockdown period, in relation to the social distancing measures adopted by Italian authorities.

Conclusions

Adults with HF-ASDs presented higher rates of depression, anxiety, stress and PTSD-related symptoms than NA during the first two months of COVID-19 pandemic. However, they also reported to feel subjectively more comfortable and less tired during the lockdown than before, in relation to the social distancing measures.

Cultivating Self-Compassion to Improve Mental Health in Autistic Adults

Many autistic adults experience poor mental health. Research has consistently shown that cultivating self-compassion is a promising approach to strengthening resilience in nonautistic adults. Self-compassion is a trainable skill that is associated with several mental health benefits, such as higher levels of happiness and well-being as well as lower symptoms of depression and anxiety. However, no studies to date have explored self-compassion in autistic individuals. We suggest that self-compassion may be a relevant target in mental health interventions for autistic adults without severe or profound intellectual disability. Self-compassion may improve mental health in autistic adults through directly modifying emotions (as an emotion regulation strategy) or its interactions with emotion regulation processes. Existing approaches to cultivating self-compassion include identifying and practicing self-compassionate behaviors, using self-compassionate thought records, and practicing self-compassion meditations. Before self-compassion approaches are implemented by autistic adults, it will be necessary to evaluate their role and effectiveness in mental health through carefully designed studies. We suggest that researchers should first study the relationship between self-compassion and mental health outcomes in autistic adults. Once researchers have established the connection, we can then begin to study self-compassion-based interventions for autistic adults. Relevant clinical considerations include identifying the autistic groups that self-compassion practices are suitable for, determining how autistic adults with and without mental health conditions can effectively practice self-compassion (on their own and with the support of clinicians), and evaluating existing self-compassion tools or designing new tools. It is also relevant for future research to identify the enablers and barriers to using self-compassion in autistic adults.

Lay summary

What is self-compassion?: Self-compassion is when we: are friendly toward ourselves (kindness)are aware of our feelings and thoughts (mindful awareness)realize that everyone feels pain and makes mistakes (common humanity)What is the purpose of this article?: We think that practicing self-compassion is important for autistic adults. No research has studied self-compassion in autistic individuals. We provide examples of how to improve self-compassion. We make recommendations for future research on self-compassion for autistic adults.What perspectives do the authors bring to this subject?: We bring together different and unique perspectives in this article. One author is a researcher whose research has focused on emotion regulation and mental health in autistic youth and adults. The other author is a self-compassion researcher who is also a private practice clinical psychologist. We have practiced self-compassion and personally experienced the benefits of developing our self-compassion skills. We think that cultivating self-compassion has helped to improve our mental health and enriched our lives.Why is self-compassion important?: Self-compassion is associated with a lot of positive aspects of life in nonautistic individuals. These positive aspects include greater happiness and well-being, and lower levels of depression and anxiety symptoms.How is self-compassion relevant to autistic adults?: We know that as a group, autistic adults have poorer mental health when compared with nonautistic adults. That is, autistic adults experience higher rates of anxiety and depression. Research shows that practicing self-compassion in nonautistic people can improve their mental health. We think that cultivating self-compassion can also be helpful to autistic adults.What do the authors recommend?: We suggest that cultivating self-compassion may improve the mental health of autistic adults. There are several ways to improve self-compassion. Self-compassion can be improved by identifying and practicing self-compassionate behaviors. For example, we can take a walk outside. Another way to improve self-compassion is to record our thoughts. This can be performed by keeping a log of self-critical thoughts. We can also practice self-compassion by meditating. It is too early to tell how self-compassion should be practiced by autistic adults. Research is needed to observe if self-compassion is helpful to autistic adults. We made a series of recommendations for researchers and clinicians. Researchers should first check if there is a relationship between self-compassion and mental health in autistic adults. If more self-compassion is associated with better mental health, then researchers and clinicians can try and find out how we can improve autistic people's self-compassion.How will these recommendations help autistic adults now or in the future?: We hope that our recommendations will start a conversation on the relevance of self-compassion for autistic adults and lead to the development of self-compassion-related research programs that involve autistic adults. The ultimate goal is to improve the mental health and psychological well-being of autistic adults in the future.

Social anxiety symptoms in autism spectrum disorder and social anxiety disorder: Considering the reliability of self-report instruments in adult cohorts

Adults with autism spectrum disorder (ASD) are at elevated risk for social anxiety disorder (SAD). Limited information exists on the reliability of social anxiety instruments with these adults and their performance when compared to individuals with SAD without ASD. This study examines psychometric properties of self-report social anxiety instruments in autistic adults without intellectual disability, compared to adults with SAD. Additionally, we compared instrument scores between a subgroup of autistic adults with a dual diagnosis of SAD (ASD + SAD) and adults with SAD only. Adults diagnosed with SAD (N = 316) or ASD (N = 102) were recruited from the Brain and Mind Centre in New South Wales, Australia. Sixty autistic participants also received a diagnosis of SAD (ASD + SAD). Participants completed the Liebowitz Social Anxiety Scale-self-report, the Social Interaction Anxiety Scale, the Social Phobia Scale, and the Brief Fear of Negative Evaluation Scale. All instruments showed excellent internal consistency in autistic adults. The instruments showed evidence of convergent validity, and the strength of relationships between measures were equivalent between ASD and SAD groups. For all instruments, performance of these instruments in autistic adults with a SAD diagnosis was very similar to performance in adults diagnosed with SAD but without ASD. Findings support the use of these instruments for identifying social anxiety symptoms in autistic adults without intellectual disability and have utility for mental health clinical services. LAY SUMMARY: Autistic adults often experience social anxiety. We examined the use of four social anxiety questionnaires in autistic adults, compared to adults with SAD. We found similar results between autistic adults and adults with SAD, suggesting that these questionnaires can be useful for measuring social anxiety symptoms in autistic adults. These findings have implications for clinical services, as they show that these instruments are reliable when used with autistic adults.

Selective Mutism and Its Relations to Social Anxiety Disorder and Autism Spectrum Disorder

In current classification systems, selective mutism (SM) is included in the broad anxiety disorders category. Indeed, there is abundant evidence showing that anxiety, and social anxiety in particular, is a prominent feature of SM. In this article, we point out that autism spectrum problems in addition to anxiety problems are sometimes also implicated in SM. To build our case, we summarize evidence showing that SM, social anxiety disorder (SAD), and autism spectrum disorder (ASD) are allied clinical conditions and share communalities in the realm of social difficulties. Following this, we address the role of a prototypical class of ASD symptoms, restricted and repetitive behaviors and interests (RRBIs), which are hypothesized to play a special role in the preservation and exacerbation of social difficulties. We then substantiate our point that SM is sometimes more than an anxiety disorder by addressing its special link with ASD in more detail. Finally, we close by noting that the possible involvement of ASD in SM has a number of consequences for clinical practice with regard to its classification, assessment, and treatment of children with SM and highlight a number of directions for future research.

TrASDition Training: An online parental training for transition-age youth with autism spectrum disorder

Transition to the adult age represents a rather challenging period of life for youth with Autism Spectrum Disorder (ASD) and for their families. Given the actual lack of integrated healthcare systems for autistic young-adults, enhancing parental skills could represent a feasible program to improve skills preparatory for transition in adult life. The online approach, providing easy access to services which otherwise would burden a daily family organization, already strenuous for a family with an autistic person, can represent an innovative way of delivering intervention. Therefore, we developed an online psychoeducational parental training, named TrASDition Training, with a 6 months duration, addressed to parents of autistic youth with and without Intellectual Disability during the transition age. The aim of this study was to longitudinally evaluate the impact of the online parental training on the adaptive functioning, on the repetitive and problematic behaviors of ASD youth (n = 23) and on parental stress. After 6 months of Training, we found a significant improvement in adaptive functioning of ASD participants and a reduction of parental stress.

Cannabis and cannabinoid use in autism spectrum disorder: a systematic review

INTRODUCTION

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by persistent deficits in social communication and social interaction, associated with the presence of restricted and repetitive patterns of behavior, interests, or activities. Cannabis has been used to alleviate symptoms associated with ASD.

METHOD

We carried out a systematic review of studies that investigated the clinical effects of cannabis and cannabinoid use on ASD, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA checklist). The search was carried out in four databases: MEDLINE/PubMed, Scientific Electronic Library Online (SciELO), Scopus, and Web of Science. No limits were established for language during the selection process. Nine studies were selected and analyzed.

RESULTS

Some studies showed that cannabis products reduced the number and/or intensity of different symptoms, including hyperactivity, attacks of self-mutilation and anger, sleep problems, anxiety, restlessness, psychomotor agitation, irritability, aggressiveness perseverance, and depression. Moreover, they found an improvement in cognition, sensory sensitivity, attention, social interaction, and language. The most common adverse effects were sleep disorders, restlessness, nervousness and change in appetite.

CONCLUSION

Cannabis and cannabinoids may have promising effects in the treatment of symptoms related to ASD, and can be used as a therapeutic alternative in the relief of those symptoms. However, randomized, blind, placebo-controlled clinical trials are necessary to clarify findings on the effects of cannabis and its cannabinoids in individuals with ASD.

'I Felt Like I was Floating in Space': Autistic Adults' Experiences of Low Mood and Depression

It is recognised that a high proportion of adults on the autism spectrum experience depressive symptoms. However, limited research has explored autistic peoples' experiences of low mood and depression. The aim of this study was to explore the lived experiences of low mood and depression for adults on the autism spectrum. The study employed Interpretive Phenomenological Analysis to investigate the experiences of 8 adults (7 males and 1 female), aged between 19 and 51, who had a diagnosis of autism without co-occurring learning disabilities, and experienced low mood or depression. All participants recorded their thoughts and feelings in a mood diary for 1 week and participated in a semi-structured interview. Three superordinate themes emerged from the data: 'Autism has made me the person I am', 'I can't function in the world' and 'It's like trying to do accounts on the futures market': Making sense of emotions. Findings highlight a need for specialist mental health provision for adults who are on the autism spectrum. Limitations of this study and implications for future research are discussed.

Similarity of subjective symptoms between autism spectrum disorder and attention-deficit/hyperactivity disorder in adults: Preliminary findings

Aim

The purpose of this study was to examine the symptoms of autism spectrum disorder (ASD) and attention‐deficit/hyperactivity disorder (ADHD) in the adult clinical population using the Autism‐Spectrum Quotient (AQ) and the Adult ADHD Rating Scales self‐report screening version (CAARS‐S:SV).

Methods

We included 50 adults with ASD and 52 with ADHD diagnosed using the DSM‐5 criteria. Clinical symptoms were evaluated using the AQ and CAARS‐S:SV.

Results

The AQ score was elevated in the ADHD group and the CAARS scores were increased in the ASD group. Specifically, the total AQ score in adults with ADHD was lower than that in the ASD group, but was higher than that in controls. Similarly, the CAARS scores in adults with ASD were lower than in those with ADHD, but were higher than those in controls. No significant correlations were found between AQ, CAARS Inattention/Memory Problems, and CAARS Hyperactivity/Restlessness scores in both the ASD and ADHD groups.

Conclusion

While adults with ASD and ADHD exhibited similar clinical symptoms, the absence of AQ‐CAARS correlations suggests the need for examining factors other than the apparent similarity of clinical symptoms of the two disorders.

The subjective symptoms of autism spectrum disorder (ASD) and attention‐deficit/hyperactivity disorder (ADHD) were examined using the Autism‐Spectrum Quotient (AQ) and the Adult ADHD Rating Scales self‐report screening version (CAARS‐S:SV) in 50 adults with ASD and 52 with ADHD. Although we excluded individuals with comorbid ASD and ADHD, the AQ score was elevated in the ADHD group and the CAARS scores were increased in the ASD group. Moreover, no significant correlations were found between AQ and CAARS scores in both ASD and ADHD groups, suggesting the need for examining factors other than shared genetic risks in the overlap of ADHD‐ASD symptoms.

Anxiety and Depression from Adolescence to Old Age in Autism Spectrum Disorder

This study examined age trends in anxious and depressive symptoms, from older adolescence to old age, and explored the association between anxious and depressive symptoms with gender, ASD severity, and socio-economic factors. Two hundred and fifty-five individuals with ASD (151 males, M_age = 33.52 years, SD_age = 14.98) took part. More than one-third of participants reported clinically significant anxiety (38.4%) or depression (38%). A slight trend for an increase in the severity of both anxiety and depression from adolescence to middle adulthood, and then a slight decline in older adulthood was found. Female gender and higher ASD severity predicted more anxiety and depression symptoms. Our findings emphasise the need to provide timely assessment and treatment of anxiety and depression in ASD.

Autism Spectrum Disorder and Medical Cannabis: Review and Clinical Experience

Autism spectrum disorder (ASD) is a multifactorial, pervasive neurodevelopmental disorder defined by the core symptoms of significant impairment in social interaction and communication as well as restricted, repetitive patterns of behavior. In addition to these core behaviors, persons with ASD frequently have associated noncore behavioral disturbance (ie, self-injury, aggression), as well as several medical comorbidities. Currently, no effective treatment exists for the core symptoms of ASD. This review reports the available preclinical and clinical data regarding the use of cannabis and cannabidiol in the treatment of core symptoms, noncore symptoms and comorbidities associated with ASD. Additionally, we describe our clinical experience working with children and young adults with ASD who have used cannabis or cannabidiol. At present, preclinical and clinical data suggest a potential for therapeutic benefit among some persons with ASD and that it is overall well tolerated. Further research is required to better identify patients who may benefit from treatment without adverse effects.

Validation of the 21-item Depression, Anxiety, and Stress Scales (DASS-21) in individuals with autism spectrum disorder

The purpose of the study was to examine the internal consistency and validity of the 21-item Depression Anxiety Stress Scale (DASS-21) in individuals with Autism Spectrum Disorder (ASD) and without intellectual disability (IQ >= 70). Participants (NN = 123) were consecutively recruited from the Brain and Mind Centre in New South Wales, Australia. Internal consistency was determined using Cronbach's alpha. Item-total correlations were evaluated by Pearson's product-moment correlation coefficient. The convergent validity of the DASS-21 was examined by measuring its associations with quality of life and other measures of depression and anxiety. Factorial validity was assessed using confirmatory factor analysis. The DASS-21 demonstrated good internal consistency, adequate convergent validity, and all items exhibited satisfactory item-total correlations. Considering fit indices and factor loadings, the confirmatory factor analysis results provided support for the original 3-factor oblique model consisting of depression, anxiety, and stress factors. The model fit could be further improved with some modifications. Overall, the results indicate that the DASS-21 is a viable self-report screening measure for depression, anxiety, and stress in individuals with ASD and without intellectual disability.

Higher depressive symptoms in early adolescents with Autism Spectrum Disorder by self- and parent-report compared to typically-developing peers

BACKGROUND

Depression is more prevalent among male early adolescents with Autism Spectrum Disorder (ASD) than their typically- developing (TD) peers, but findings are limited to two male-only studies. Therefore, a broader understanding of depressive symptoms among both male and female early adolescents with ASD in larger samples is needed. Self- and parent-ratings are frequently used, yet rater differences may emerge and provide unique insights.

METHOD

Ratings of adolescent depressive symptoms were examined among 230 early adolescents (10:0-13:5 years) with and without ASD using self- (Children's Depression Inventory, Second Edition; CDI-2) and parent- report (Child Behavior Checklist; CBCL) measures. The influence of diagnostic group (ASD vs. TD) and rater (early adolescent vs. parent) on ratings were examined with Full Scale IQ and sex as covariates. Additionally, the reliability and strength of agreement between raters were examined.

RESULTS

Higher depressive symptoms were reported by both raters in the ASD group (Borderline range) compared to the TD group (Average range). The interaction of diagnostic group and rater was nonsignificant, but significant main effects emerged. Sex was a significant covariate, but Full Scale IQ was not. The reliability and strength of agreement between raters in the ASD group only were not significant.

CONCLUSIONS

Findings suggest that depressive symptoms may be higher in both male and female early adolescents with ASD across self- and parent- reports. However, measurement of depression in ASD may be complicated by nonsignificant reliability and strength of agreement between raters. Results have implications for screening and intervention for early adolescents with ASD.

Dysregulation of translational control signaling in autism spectrum disorders

Deviations from the optimal level of mRNA translation are linked to disorders with high rates of autism. Loss of function mutations in genes encoding translational repressors such as PTEN, TSC1, TSC2, and FMRP are associated with autism spectrum disorders (ASDs) in humans and their deletion in animals recapitulates many ASD-like phenotypes. Importantly, the activity of key translational control signaling pathways such as PI3K-mTORC1 and ERK is frequently dysregulated in autistic patients and animal models and their normalization rescues many abnormal phenotypes, suggesting a causal relationship. Mutations in several genes encoding proteins not directly involved in translational control have also been shown to mediate ASD phenotypes via altered signaling upstream of translation. This raises the possibility that the dysregulation of translational control signaling is a converging mechanism not only in familiar but also in sporadic forms of autism. Here, we overview the current knowledge on translational signaling in ASD and highlight how correcting the activity of key pathways upstream of translation reverses distinct ASD-like phenotypes.

Impact of Sensory Processing on School Performance Outcomes in High Functioning Individuals with Autism Spectrum Disorder

Difficulty processing sensory information may impede progress in school for students with autism spectrum disorder (ASD). We explore the relationship between sensory processing and school performance in 26 high-functioning youths with ASD and 26 controls (age 8-14) using measures of sensory, social, cognitive, and academic functioning. In the ASD group, bivariate Pearson correlations indicated a significant positive relationship between intelligence quotient (IQ) and the School Competence Scale (SCS) of the Child Behavior Checklist (CBCL), and a significant negative relationship between Dunn's Sensory Processing Framework and SCS scores. Final hierarchical multiple linear regression model accounting for SCS scores in ASD included IQ, ADHD symptoms, and sensory features. An interaction between increased sensory sensitivity with reduced sensory avoidance behaviors explained the greatest amount of variance in SCS, meaning school performance is lowest for children with greater hypersensitivity and fewer avoidance behaviors. Results indicate a strong impact of sensory processing on school performance in ASD.

Psychometric properties of the Emotional Quotient Inventory: Youth Version-EQ-i:YV in Spanish adolescents with Down syndrome

BACKGROUND

The people with Down syndrome who are now adolescents can face a self-report questionnaire with guarantees of being answered with validity to evaluate areas of development that traditionally have not been able to be evaluated. This is the case of emotional intelligence, measured in this research with the Emotional Quotient Inventory: Youth Version-EQ-i:YV.

AIMS

To validate and analyse the scale's psychometric properties in adolescents with Down syndrome.

METHODS

A two-stage cross-sectional investigation was conducted. The inventory consists of 60 items that measure 5 dimensions. The test was administered to 644 adolescents with Down syndrome. We carried out exploratory and confirmatory factor analyses.

OUTCOMES

The 5-factor structure of the test was confirmed. The internal consistency of four dimensions and the EQ-i:YV's total calculated score yielded high values.

CONCLUSIONS

This new version of the EQ-i:YV represents a valid and reliable tool to assess emotional intelligence in Spanish adolescents with Down syndrome.

Psychiatric comorbidities in Asperger syndrome are related with polygenic overlap and differ from other Autism subtypes

There is great phenotypic heterogeneity within autism spectrum disorders (ASD), which has led to question their classification into a single diagnostic category. The study of the common genetic variation in ASD has suggested a greater contribution of other psychiatric conditions in Asperger syndrome (AS) than in the rest of the DSM-IV ASD subtypes (Non_AS). Here, using available genetic data from previously performed genome-wide association studies (GWAS), we aimed to study the genetic overlap between five of the most related disorders (schizophrenia (SCZ), major depression disorder (MDD), attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorders (OCD) and anxiety (ANX)), and AS, comparing it with the overlap in Non_AS subtypes. A Spanish cohort of autism trios (N = 371) was exome sequenced as part of the Autism Sequencing Consortium (ASC) and 241 trios were extensively characterized to be diagnosed with AS following DSM-IV and Gillberg's criteria (N = 39) or not (N = 202). Following exome imputation, polygenic risk scores (PRS) were calculated for ASD, SCZ, ADHD, MDD, ANX, and OCD (from available summary data from Psychiatric Genomic Consortium (PGC) repository) in the Spanish trios' cohort. By using polygenic transmission disequilibrium test (pTDT), we reported that risk for SCZ (P_scz= 0.008, corrected-P_SCZ = 0.0409), ADHD (P_ADHD = 0.021, corrected-P_ADHD = 0.0301), and MDD (P_MDD = 0.039, corrected-P_MDD = 0.0501) is over-transmitted to children with AS but not to Non_AS. Indeed, agnostic clustering procedure with deviation values from pTDT tests suggested two differentiated clusters of subjects, one of which is significantly enriched in AS (P = 0.025). Subsequent analysis with S-Predixcan, a recently developed software to predict gene expression from genotype data, revealed a clear pattern of correlation between cortical gene expression in ADHD and AS (P < 0.001) and a similar strong correlation pattern between MDD and AS, but also extendable to another non-brain tissue such as lung (P < 0.001). Altogether, these results support the idea of AS being qualitatively distinct from Non_AS autism and consistently evidence the genetic overlap between AS and ADHD, MDD, or SCZ.

Assessment of emotional intelligence in adults with down syndrome: Psychometric properties of the Emotional Quotient Inventory

Introduction

The Emotional Quotient Inventory: Youth version-EQ-i:YV was developed by Bar-On & Parker in 2000 and later translated and adapted for the general Spanish adolescent population by Ferrandiz et al. in 2012. The Spanish scale presents similar psychometric properties to the original version (54 items and five subdimensions). The Emotional Quotient Inventory assesses a set of personal, emotional, and social skills that influence adaptation to and coping with environmental demands and pressures. These factors can influence an adolescent’s success later in life, health, and psychological well-being. Traditionally, research in Down syndrome (DS) has focused on identifying cognitive deficits, relatively little is known about emotional intelligence (EI) and there are no scales that measure EI in people with DS adults.

Objectives

To validate and analyze the psychometric properties of the scale in the clinical population, specifically in Spanish adults with DS (EQ-i: SVDS).

Methods

A cross-sectional investigation was carried out in several stages. Descriptive, exploratory factorial (n = 345), confirmatory (n = 397), and scale reliability analyses were performed with better goodness-of-adjustment indices.

Results

A new scale named Emotional Quotient Inventory: Short Version for DS adults was obtained with a structure of four factors called mood, stress management, interpersonal, and intrapersonal. This new scale was reduced to 25 items. Goodness-of-fit indices were excellent (RMSEA [95% CI] = 02[.01; .03]; CFI = .99; TLI = .98; GFI = .87; AGFI = .89). The internal consistency of the four dimensions and the calculated total score (α = .91, ω = .93 and divided halves = .90) yielded high values in this clinical sample.

Discussion

The results recommend the use of the revised EQ-i: YV, the EQ-i: SVDS, to assess EI in adults with DS. The psychometric properties of this study are satisfactory but have four factors. The findings are discussed in terms of future research and practical implication to gain a more thorough understanding of how this population behaves on both a general and preventive level in order to teach EI properly.

Conclusions

This new version is a valid and reliable tool to evaluate emotional intelligence in people with intellectual disabilities and specifically in Spanish adults with DS.

The Sensory Abnormalities and Neuropsychopathology of Autism and Anxiety

Autism spectrum disorder (ASD) is a developmental disorder of interpersonal communications and restricted interest and deficits in sensory and social interactions. It co-occurs with anxiety and mostly in 30% of cases related to specific phobia. This review article summarises the sensory association between anxiety and ASD. The role of emotions and neurobiology discussed and sensory over-reactivity (SOR) was related to ASD and anxiety. PubMed database systematically searched for related articles on ASD and anxiety. The keywords used are autism spectrum disorder, autism spectrum disorder and emotion, anxiety disorder, sensory in autism and anxiety, and psychopathology. The results were most significant and related to the sensory association between ASD and anxiety. Out of 19 studies discussed, there were eight systematic reviews with meta-analysis, seven systematic reviews, three traditional reviews, and one included both systematic reviews with randomized controlled trials (RCTs). However, due to possible limitations and considerations, like small sample size and few clinical trials; hence, further recommendations to randomized clinical trials and cohort studies warranted. This review article helps scientists to plan and focus on necessary studies and possible screening for the disease to improve possible clinical outcomes. People gain awareness of the disease. Early recognition, as well as educational, behavioral, and family therapy, might decrease symptoms and support learning and development in children.

Communication Profile of a Minimally Verbal School-Age Autistic Child: A Case Study

Purpose The present clinical focus draws on an intrinsic case study to provide a thick description of the communication profile of John, a 9-year-old minimally verbal autistic student. Method Specifically, traditional behavioral assessments, classroom video observations, and semistructured interviews were used to gather information regarding John's communication profile and potential sensory-motor differences. Results Convergent evidence indicated that John's expressive profile was characterized by single words, emergent word combinations, some conventional gestures, and a low frequency of communicative initiations. Concomitant language comprehension challenges and poor intelligibility associated with motor speech impairment were also indicated. His sensory-motor profile was marked by fine motor impairment, relative strengths in gross motor abilities, and sensory differences across visual, hearing, and tactile modalities. Conclusion Direct implications for supporting minimally verbal autistic students like John include the need to (a) consider sensory-motor influences on social interaction and (b) support flexible use of multimodal communication resources, including augmentative and alternative communication.

Socio-emotional determinants of depressive symptoms in adolescents and adults with autism spectrum disorder: A systematic review

LAY ABSTRACT

Many adolescents and adults with autism spectrum disorder experience difficulty with symptoms of depression. These symptoms can contribute to poor quality of life and lack of independence for adolescents and adults. To better understand these symptoms, we conducted a review of articles that examined the presentation of depression specific to autism spectrum disorder. Our goals in conducting this study were (1) to examine whether depression may be associated with symptoms that are common among people with autism spectrum disorder, such as loneliness or poor social motivation; (2) to determine whether people with autism spectrum disorder experience depression in a different way than the general population; and (3) to add to other recent studies that have examined how common depression is in autism spectrum disorder and how it is typically measured. Our study reviewed 48 papers on this topic. Results showed that a substantial proportion of people with autism spectrum disorder experience significant symptoms of depression. We related our results to social factors commonly studied in this field (i.e. social motivation) and proposed a new model for the development of depression in this population.

Preliminary Study on Psychometric Properties of an Anxiety Scale in Down Syndrome with Anxiety Symptoms

BACKGROUND

anxiety remains one of the most common disorders in typically developing children and young adults. Adolescents with Down syndrome (DS) lack diagnostic tests for evaluation.

METHODS

this study evaluated the psychometric properties of the Screen for Child Anxiety Related Emotional Disorders inventory in its self-report version in 63 adolescents with anxiety symptoms with DS. The inclusion criteria for the studies were trisomy 21 and a chronological age between 8 and 17 years. Psychometric properties arestrictly evaluated with the sample exceeding a cutoff point in anxiety symptomatology. A confirmatory factorial analysis tested two models for the new evaluation test.

RESULTS

both models confirmed a four-factor structure (somatic/panic, social phobia, generalized anxiety, and separation anxiety). Model 2, nevertheless, had fewer items and a better fit, and it also showed a high correlation with other anxiety detection measures and adequate internal consistency.

CONCLUSIONS

the importance of validating psychopathological anxiety tests for children and young people with DS in order to build good mental health is discussed, emphasizing the need to provide easy and short-term tests on cognitive and emotional aspects in people with intellectual disabilities.

Treatment Gains from Early and Intensive Behavioral Intervention (EIBI) are Maintained 10 Years Later

This study reports outcome in adolescents with autism who in their childhood received Early and Intensive Behavioral Intervention (EIBI). Nineteen children (16 boys) who had received two years of EIBI starting at a mean age of 2-years-and-11-months were followed up, on average, 12 years later. Results showed the participants significantly increased their cognitive and adaptive standard scores during the two years of EIBI, and that these gains were maintained at follow-up, 10 years after the EIBI had ended. Participants also showed a significant reduction in autism symptoms between intake and follow-up. At follow-up, none of the participants had received any additional psychiatric diagnoses, and none were taking any psychotropic medication. Results indicate that treatment gains achieved in EIBI are maintained into adolescence.

[ADI-R and ADOS and the differential diagnosis of autism spectrum disorders: Interests, limits and openings]

INTRODUCTION

Current developments in international public health are leading qualified authorities to release clinical practice guidelines for Autism Spectrum Disorders (ASD) assessment and diagnosis. Such documents incorporate procedures that rely on the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS) which are considered to be the "gold standard" assessment measures in the evaluation of ASD. Although these tools do prove their effectiveness in the evaluation of autistic symptomatology, they nevertheless stumble whenever the situation becomes more complex and reveal differential diagnostic issues in infantile and adult autism cases. This differential diagnostic issue remains significant in the clinical practice of daily life and has strong implications for the course of therapeutic treatment.

OBJECTIVES

Our objective is to underline and nuance the metrological qualities of the ADI-R and the ADOS in the differential diagnosis of autistic disorders by presenting a synthesis of recent studies, thus supporting the interest of maintaining an open debate on diagnostic practices.

METHODS

Our selective review of the recent literature focuses on studies that confront the ADI-R and the ADOS - used either independently or in a combination - with various differential issues in adulthood and childhood autism in order to highlight their qualities and limits.

RESULTS

The ADI-R is a semi-structured interview applied by trained examiners and applied to relatives and/or caregivers who collect developmental information about the patient's first years of life on a variety of behaviors and skills. It is therefore relatively dependent on the availability and personal bias of the interviewed third parties. Metric features highlighted by the reviewed studies straightforwardly reveal a certain effectiveness of the tool and a good discrimination of childhood disorders. At the same time, the tool's discriminatory capacity seems insufficient when applied to toddlers, very young children, and adults alike. The latter seems particularly true when it comes to differentiating between autistic and schizophrenic spectrum disorders. The ADOS is a semi-structured standardized observation assessment tool that has experienced several successive developments, such as optimizations concerning the sensitivity of its cutoffs. Many works have contributed to building such a tool with reliable and solid metric qualities which nevertheless retain important biases such as the subjectivity of the caregiver or the evaluator during the scoring process. For assessments of autistic children the tool still has a good diagnostic validity but seems to retain cases of incorrect diagnosis of ASD (false positives). In other words, disorders or developmental disabilities of some children and adolescents could not be distinguished from ASD when relying on this test alone. The ADOS Module 4, designed for the diagnosis of adolescents and adults with fluent speech, has undergone less updating. This revisited algorithm has metrological qualities useful for clinicians and remains one of the few available tools for this population. Unfortunately, its diagnostic accuracy is lower when applied to women, the elderly, people with personality disorders or higher intellectual abilities, or for the discrimination between ASD and schizophrenia. Overall, scores from these two instruments bring strong evidence of their usefulness in the diagnostic process of ASD, provided that they are used with caution and a critical clinical perspective, and only as a secondary technical support. Their use in combination is effective since they are complementary and compensate for each other's limitations. However, their globalized hegemony as "gold-standard" tools constitutes a setback insofar as it constrains the diagnosis of ASD to a set of stereotyped items. The latter in turn sets a normative model of autism that excludes other phenotypic forms, especially in the case of women and the elderly. Finally, the discrimination between autism and psychosis for children seems to remain an insoluble task even for the ADI-R/ADOS combination.

CONCLUSIONS

The problematics of differential diagnosis remain critical for clinical approaches to autism. Therefore, formalizations of the diagnostic procedures must be able to remain open-minded and accompanied by a creative clinical approach, especially in the case of complex situations that are not soluble by means of conventional diagnostic tools. One possibility may lie in the deepening of the phenomenological approach to autism as an attempt to model the subjective phenomena of autistic subjects and thus operationalize elements that serve the diagnostic process. In the same way, a psychodynamic epistemology could help clinicians to go beyond the consideration of observable behaviors and scores, introducing a psychoanalytic point of view that interfaces objective behaviors with the individual's dynamic intrapsychic functioning. This project could be articulated with projective methodologies - notably the Rorschach test - which respects the needs for standardization and quantification of conventionally used diagnostic tools.

Prevalence and comorbidity of autism spectrum disorder in Spain: study protocol for a systematic review and meta-analysis of observational studies

BACKGROUND

Autism spectrum disorder (ASD) is a complex developmental disorder characterised by impaired social interaction and communication, and restrictive and repetitive behaviour. Previous systematic reviews have traditionally assessed the prevalence of ASD on global or regional context, with very few meta-analyses at the country level. The objective of this study will be to systematically evaluate published and unpublished observational studies that present prevalence and comorbidity of ASD among children, adolescent and adult population in Spain.

METHODS/DESIGN

We designed and registered a study protocol for a systematic review and meta-analysis of descriptive epidemiology data. Observational studies (cohort, cross-sectional) reporting the prevalence of ASD and conducted in a wide range of people (e.g. general population, outpatient and/or school settings) will be included. The primary outcome will be the prevalence of ASD. Secondary outcomes will be the prevalence of any physical or mental comorbidity in association with ASD. No limitations will be imposed on publication status, study conduct period, and language of dissemination. Comprehensive literature searches will be conducted in seven electronic databases (from January 1980 onwards), including PubMed/MEDLINE, EMBASE, Scopus, Web of Science, PsycINFO, IME-Spanish Medical Index and IBECS-Spanish Bibliographic Index of Health Sciences. Grey literature will be identified through searching dissertation databases, Google Scholar and conference abstracts. Two team members will independently screen all citations, full-text articles, and abstract data. Potential conflicts will be resolved through discussion. The study methodological quality (or bias) will be appraised using an appropriate tool. If feasible, we will conduct random effects meta-analysis of observational data. Prevalence estimates will be stratified according to gender, age and geographical location. Additional analyses will be conducted to explore the potential sources of heterogeneity (e.g. methodological quality, sample size, diagnostic criteria).

DISCUSSION

This systematic review and meta-analysis of observational data will identify, evaluate and integrate the epidemiological knowledge underlying the prevalence of ASD in Spain. The results of this study will be of interest to multiple audiences including patients, their families, caregivers, healthcare professional, scientists and policy makers. Results will be published in a peer-reviewed journal. Implications for future epidemiological research will be discussed.

A 'choice', an 'addiction', a way 'out of the lost': exploring self-injury in autistic people without intellectual disability

Background

Non-suicidal self-injury (NSSI) describes a phenomenon where individuals inflict deliberate pain and tissue damage to their bodies. Self-injurious behaviour is especially prevalent across the autism spectrum, but little is understood about the features and functions of self-injury for autistic individuals without intellectual disability, or about the risk factors that might be valuable for clinical usage in this group.

Methods

One hundred and three autistic adults who responded to an online advertisement were classified as current, historic or non-self-harmers in accordance with responses to the Non-Suicidal Self-Injury Assessment Tool (NSSI-AT). Multinomial regression aimed to predict categorisation of participants in accordance with scores on tests of autistic traits, alexithymia, depression, anxiety, mentalising and sensory sensitivity. Linear regression examined relationships between these predictors and the range, frequency, lifetime occurrence and functional purposes of NSSI. Qualitative analysis explored the therapeutic interventions that participants had found helpful, and what they wished people understood about self-injury.

Results

Current, historic and non-self-harming participants did not differ in age, age at diagnosis, male-to-female ratio, level of employment or education (the majority qualified to at least degree level). The most common function of NSSI was the regulation of low-energy affective states (depression, dissociation), followed by the regulation of high-energy states such as anger and anxiety. Alexithymia significantly predicted the categorisation of participants as current, historic or non-self-harmers, and predicted use of NSSI for regulating high-energy states and communicating distress to others. Depression, anxiety and sensory-sensitivity also differentiated participant groups, and sensory differences also predicted the range of bodily areas targeted, lifetime incidence and frequency of NSSI. Sensory differences, difficulty expressing and identifying emotions also emerged as problematic in the qualitative analysis, where participants expressed the need for compassion, patience, non-judgement and the need to recognise diversity between self-harmers, with some participants perceiving NSSI as a practical, non-problematic coping strategy.

Conclusions

Alexithymia, depression, anxiety and sensory differences may place some autistic individuals at especial risk of self-injury. Investigating the involvement of these variables and their utility for identification and treatment is of high importance, and the voices of participants offer guidance to practitioners confronted with NSSI in their autistic clients.

Identifying Language for People on the Autism Spectrum: A Scoping Review

Person-first language is considered a central component to recovery oriented person-centred care; however, there is a growing adoption of identify-first language among autistic advocates. Mental health nurses require awareness of critical autism issues given the high prevalence of comorbid psychopathology. This scoping review of literature from 2010 to 2018 regarding identifying language for people on the autism spectrum identified a paucity of research that systematically explored and considered antagonisms, representation, and potential consequences of either of the current modes of identifying language becoming dominant. Mental health nurses should appreciate the complexity within identifying language and adopt context dependent language.

Psychiatric comorbidity in persons with high-functioning autism spectrum disorders: Findings from a tertiary care neuropsychiatric hospital

BACKGROUND

The literature on co-morbid psychiatric illnesses in adults with high-functioning autism (HFA) spectrum disorder is sparse.

PURPOSE

To examine the nature of psychiatric comorbidity and treatment response in adults with HFA spectrum disorder.

MATERIALS AND METHODS

Case records of subjects (age ≥17 years) who presented over a period of 16 years with primary psychiatric symptoms and further detected to have an HFA spectrum disorder, were analyzed. Autism spectrum disorders (ASD) along with near normal to normal verbal communication and general intelligence were considered as HFA spectrum disorders.

RESULTS

33 subjects met the study criteria. Nine subjects (27%) were diagnosed to have an underlying Asperger's syndrome and the rest 24 (73%) had pervasive developmental disorders unspecified (PDD NOS). None of the subjects were diagnosed to be suffering from ASD prior to the visit to our hospital. Mean age at the time of psychiatric consultation was 22.7 (s.d=4.8) years and mean age at the onset of psychiatric comorbidity was 16.48 (s.d=4.4) years. Nearly half of the sample had more than one type of psychiatric illness. Most common lifetime psychiatric diagnosis was obsessive-compulsive disorder (OCD) (n=16, 48.4%). Bipolar disorder (BD) was the second most common type of psychiatric manifestation (n=13, 39.3%) followed by psychotic spectrum disorders (n=9, 27.2%). Overall response to treatment was minimal.

CONCLUSIONS

Individuals with HFA spectrum disorders suffer from multiple psychiatric comorbidities. OCD is the most common type of psychiatric comorbidity followed by BD and psychotic spectrum disorders. Comorbid psychiatric illnesses in individuals with HFA show poor response to treatment.
