Can Autism Spectrum Disorders and Social Anxiety Disorders be Differentiated by the Social Responsiveness Scale in Children and Adolescents?

Autism spectrum disorder (ASD) as well as social phobia (SP), and selective mutism (SM) are characterised by impaired social interaction. We assessed the validity of the Social Responsiveness Scale (SRS) to differentiate between ASD, and SP/SM. Raw scores were compared in 6–18 year old individuals with ASD (N = 60), SP (N = 38), SM (N = 43), and typically developed (N = 42). Sensitivity and specificity were examined. The three disorders showed overlapping SRS scores. Especially in boys with SM (ROC–AUC = .81), presence of ASD was overestimated by the SRS. A combination of three disorder specific questionnaires resulted in marginally improved diagnostic accuracy. For the clinically very relevant differential diagnosis of SP/SM, SRS results must be interpreted with caution.     

Anxiety Disorders and Sensory Over-Responsivity in Children with Autism Spectrum Disorders: Is There a Causal Relationship?

Anxiety disorders and sensory over-responsivity (SOR) are common in children with autism spectrum disorders (ASD), and there is evidence for an association between these two conditions. Currently, it is unclear what causal mechanisms may exist between SOR and anxiety. We propose three possible theories to explain the association between anxiety and SOR: (a) SOR is caused by anxiety; (b) Anxiety is caused by SOR; or (c) SOR and anxiety are causally unrelated but are associated through a common risk factor or diagnostic overlap. In this paper, we examine support for each theory in the existing anxiety, autism, and neuroscience literature, and discuss how each theory informs choice of interventions and implications for future studies.     

Parents’ State and Trait Anxiety: Relationships with Anxiety Severity and Treatment Response in Adolescents with Autism Spectrum Disorders

Comorbid anxiety is common among children with Autism Spectrum Disorder (ASD), and parents of children with ASD are more likely to have anxiety disorders. This study investigated the relationship between parents’ state and trait anxiety and parent-reported internalizing and externalizing symptoms among adolescents (n = 30) with ASD, as well as the relationship of parents’ anxiety symptoms and adolescent treatment response in the context of a randomized controlled trial. Parental state anxiety correlated with severity of adolescent anxiety, and trait anxiety in parents correlated with parent-reported adolescent internalizing and externalizing symptoms. Also, parents of adolescent treatment responders experienced a decrease in their own trait anxiety. Findings highlight the importance of considering parental anxiety when targeting anxiety among youth with ASD.     

Does the Presence of Anxiety and ADHD Symptoms Add to Social Impairment in Children with Autism Spectrum Disorder?

Children with autism spectrum disorder (ASD) experience internalizing and externalizing problems at higher rates than typically developing children, which could worsen social impairment. The present study compared impairment scores (social responsiveness scale, 2nd edition; SRS-2 scores) in 57 children (3–17 years, 82.5% male) with ASD, either with or without heightened levels of anxiety or ADHD symptoms, all per parent report. Children with heightened anxiety problems showed higher scores on four SRS-2 subscales (Social Cognition, Social Communication, Social Motivation, and Restricted Interests and Repetitive Behavior). Children with heightened ADHD traits showed higher scores on two subscales (Social Communication and Social Awareness). These findings suggest similarities and differences in how social deficits in ASD may worsen with anxiety or ADHD symptoms.     

Are Generalized Anxiety and Depression Symptoms Associated with Social Competence in Children with and without Autism Spectrum Disorder?

Generalized anxiety and depression symptoms may be associated with poorer social outcomes among children with Autism Spectrum Disorder (ASD) without intellectual disability. The goal of this study was to examine whether generalized anxiety and depression symptoms were associated with social competence after accounting for IQ, age, and gender in typically developing children and in children with ASD. Results indicated that for the TD group, generalized anxiety and depression accounted for 38% of the variance in social competence and for children with ASD, they accounted for 29% of the variance in social competence. However, only depression accounted for a significant amount of the variance. The findings underscore the importance of assessing the social impact of internalizing symptoms in children with ASD.     

Does Nutritional Intake Differ Between Children with Autism Spectrum Disorders and Children with Typical Development?

Consumption of macro- and micronutrients and food group servings by children with autism spectrum disorders (ASDs; n = 46) and typical development (n = 31) were compared using 3-day diet records. Children with ASDs consumed significantly more vitamin B6 and E and non-dairy protein servings, less calcium, and fewer dairy servings (p < .05). The significantly lower dairy serving intake persisted after controlling for child age and sex and parental dietary restrictions, and excluding children on the gluten-free casein-free (GFCF) diet. Large proportions of children in both groups did not meet national recommendations for daily intake of fiber, calcium, iron, vitamin E, and vitamin D.     

Efficiency of Lexical Access in Children with Autism Spectrum Disorders: Does Modality Matter?

The provision of visual support to individuals with an autism spectrum disorder (ASD) is widely recommended. We explored one mechanism underlying the use of visual supports: efficiency of language processing. Two groups of children, one with and one without an ASD, participated. The groups had comparable oral and written language skills and nonverbal cognitive abilities. In two semantic priming experiments, prime modality and prime–target relatedness were manipulated. Response time and accuracy of lexical decisions on the spoken word targets were measured. In the first uni-modal experiment, both groups demonstrated significant priming effects. In the second experiment which was cross-modal, no effect for relatedness or group was found. This result is considered in the light of the attentional capacity required for access to the lexicon via written stimuli within the developing semantic system. These preliminary findings are also considered with respect to the use of visual support for children with ASD.     

Examining Autistic Traits in Children with ADHD: Does the Autism Spectrum Extend to ADHD?

We examined to what extent increased parent reports of autistic traits in some children with Attention Deficit Hyperactivity Disorder (ADHD) are the result of ADHD-related symptoms or qualitatively similar to the core characteristics of autism spectrum disorders (ASD). Results confirm the presence of a subgroup of children with ADHD and elevated ratings of core ASD traits (ADHD⁺) not accounted for by ADHD or behavioral symptoms. Further, analyses revealed greater oppositional behaviors, but not greater ADHD severity or anxiety, in the ADHD⁺ subgroup compared to those with ADHD only. These results highlight the importance of specifically examining autistic traits in children with ADHD for better characterization in studies of the underlying physiopathology and treatment.     

Learning Curve Analyses in Neurodevelopmental Disorders: Are Children with Autism Spectrum Disorder Truly Visual Learners?

Visual and auditory verbal learning using a selective reminding format was studied in a mixed clinical sample of children with autism spectrum disorder (ASD) (n = 42), attention-deficit hyperactivity disorder (n = 83), velocardiofacial syndrome (n = 17) and neurotypicals (n = 38) using the Test of Memory and Learning to (1) more thoroughly characterize and examine the integrity of learning and memory processes, (2) to better understand the mechanisms of learning impairment, and (3) to inform instructional practices in ASD. Contrary to expectations, children with ASD demonstrated a relative weakness in the rate of acquisition of visual in contrast to verbal learning compared to neurotypicals. They also showed a complex pattern of consolidation. Overall, between-group differences were more likely to emerge during the visual learning task, suggesting that it may be more sensitive for detecting neurodevelopmental differences. The heuristic value of assessing memory and learning across multiple trials and comparing performance during immediate and delayed recall is discussed.     

Caring for a Child with Autism Spectrum Disorder and Parents’ Quality of Life: Application of the CarerQol

This study describes the impact of caregiving on parents of children with autism spectrum disorders (ASDs). Secondly, we investigate construct validation of the care-related quality of life instrument (CarerQol) measuring impact of caregiving. Primary caregivers of children with ASDs were included. Many parents experienced considerable problems combining daily activities with care, had financial problems or suffered from depressive mood. Validity tests showed that a higher impact of caring on the CarerQol was positively associated with higher subjective burden and lower family quality of life. Most of the associations between CarerQol scores and background characteristics confirmed previous research. The CarerQol validly measures the impact of caregiving for children with ASDs on caregivers in our sample. The CarerQol may therefore be useful for including parent outcomes in research on ASDs.     

Does Quality of Life Differ for Children With Autism Spectrum Disorder and Intellectual Disability Compared to Peers Without Autism?

The main goal was to test if children with intellectual disability (ID) and autism spectrum disorder (ASD) show lower quality of life (QOL) in comparison to those with only ID. The KidsLife Scale was applied to 1060 children with ID, 25% of whom also had ASD, aged 4–21 years old. Those with ASD showed lower scores in several QOL domains but, when the effect of other variables was controlled, lower scores were only kept for interpersonal relationships, social inclusion, and physical wellbeing. Slightly higher scores were found for material wellbeing. ASD, Level of ID and support needs were the covariables with the greatest influence in most domains, while gender was only significant for social inclusion (girls scored lower than boys).     

Confirmatory Factor Analysis of the Child Behavior Checklist 1.5–5 in a Sample of Children with Autism Spectrum Disorders

Validity studies of measures for emotional and behavioral disorders (EBD) for use with preschool children with autism spectrum disorders (ASD) are lacking. The Child Behavior Checklist 1.5–5 (CBCL; Achenbach and Rescorla, Manual for the ASEBA Preschool Forms & Profiles. VT: University of Vermont, Research Center for Children, Youth, and Families, Burlington, 2000), a widely used measure for EBD, contains several norm-referenced scales derived through factor analysis of data from the general pediatric population. In this study, confirmatory factor analysis of archival data evaluated the adequacy of the CBCL factor model in a well characterized sample of preschoolers with ASD (N = 128). Psychometric results supported the model and suggested that practitioners can use the CBCL to assess for EBD in young children with ASD in conjunction with other clinical data. This will increase the likelihood of accurate identification and EBD-specific intervention.

Teachers’ Perceptions Regarding the Management of Children with Autism Spectrum Disorders

This study examines Greek teachers’ perceptions related to the nature and management of autistic children. To investigate these issues, a statistically reliable number of questionnaires (n = 228) was distributed to a diversified teacher population. The questionnaire responses were analyzed statistically to identify the explanatory power of critical independent variables. The research findings support that teachers’ specialized training and working experience are critical inputs to improve teachers’ perceptions and efficient serving of autistic children. A cumulative joint effect of teachers’ previous specialized education and working experience working with autistic children was also indicated. This could be supportive of teachers upgrading their active leading role in team working with specialized scientific staff, parents and institutions on autistic children.     

Pervasive Developmental Disorders and Autism Spectrum Disorders: Are These Disorders One and the Same?

The concept of pervasive developmental disorders (PDD) and autism spectrum disorders (ASD) closely resemble each other. Both ICD-10 and DSM-IV use the term PDD. The authors surveyed the perception of PDD/ASD and attitudes toward terminology. The subjects of this study were 205 medical/social-welfare professionals working in fields relating to developmental disorders. Questionnaires were mailed to site investigators at the collaborating institutes. With regard to what the scope of ASD and PDD encompasses, the answers were almost equally divided among three views: ASD and PDD are the same, PDD is wider in scope and ASD is wider. The terms PDD and autism were used in slightly different ways depended upon the situation. Our results demonstrate that the parameters of PDD and ASD are unclear and that the terms related to PDD/ASD are often used differently. Further studies are required to develop more clear and reliable diagnostic criteria for PDD.

Profiles and Correlates of Parent–Child Agreement on Social Anxiety Symptoms in Youth with Autism Spectrum Disorder

This study characterized patterns and correlates of parent–youth agreement on social anxiety in youth with and without autism spectrum disorder (ASD). Participants (279 verbally-fluent youth aged 8–16 years, N_ASD?=?144, N_TD?=?135) completed the SASC-R. Youth with ASD exhibited higher social anxiety across informants. While TD youth endorsed higher anxiety than did parents, self- and parent-reports did not differ in youth with ASD. For children with ASD, higher parent–youth agreement was associated with lower lifetime ASD symptoms and higher adaptive skills. For TD youth, agreement on high anxiety was associated with lowest adaptive skills. Demographic factors (age, verbal IQ, gender) did not relate to agreement for either group. In ASD, parent–child agreement on youth anxiety, either high or low, was associated with better outcomes.     

What Do Repetitive and Stereotyped Movements Mean for Infant Siblings of Children with Autism Spectrum Disorders?

Repetitive and stereotyped movements (RSMs) in infancy are associated with later diagnoses of autism spectrum disorder (ASD), yet this relationship has not been fully explored in high-risk populations. The current study investigated how RSMs involving object and body use are related to diagnostic outcomes in infant siblings of children with ASD (Sibs-ASD) and typically developing children (Sibs-TD). The rate and number of different types of RSMs were measured at an average of 15 months with follow-up diagnostic evaluations approximately 18 months later. While Sibs-ASD displayed higher rates of RSMs relative to Sibs-TD, rates did not differ according to diagnostic outcome in Sibs-ASD. However preliminary evidence suggests that qualitative differences in RSM type warrant further investigation as early diagnostic markers.     

Who Participates in Support Groups for Parents of Children with Autism Spectrum Disorders? The Role of Beliefs and Coping Style

One hundred forty-nine parents of children with autism spectrum disorders (ASD) completed online questionnaires measuring their beliefs about support groups and ASD, coping style, social support, mood, and use of support groups. Those currently using parent support groups (PSGs) reported using more adaptive coping strategies than both parents who had never used PSGs and parents who had used PSGs in the past. Past PSG users reported that they did not find the groups as beneficial as current users, and parents who had never participated in PSGs reported difficulties with the accessibility of PSGs. Based on the current results, interventions for parents of children with ASD that are focused on meeting the needs identified by participating parents may be most effective.     

Is Emotion Recognition Impaired in Individuals with Autism Spectrum Disorders?

Researchers have argued that individuals with autism spectrum disorders (ASDs) use an effortful “systematizing” process to recognize emotion expressions, whereas typically developing (TD) individuals use a more holistic process. If this is the case, individuals with ASDs should show slower and less efficient emotion recognition, particularly for socially complex emotions. We tested this account by assessing the speed and accuracy of emotion recognition while limiting exposure time and response window. Children and adolescents with ASDs showed quick and accurate recognition for most emotions, including pride, a socially complex emotion, and no differences emerged between ASD and TD groups. Furthermore, both groups trended toward higher accuracy when responding quickly, even though systematizing should promote a speed-accuracy trade-off for individuals with ASDs.
