Executive functioning as a predictor of peer victimization in adolescents with and without an Autism Spectrum Disorder

The present study examined pragmatic language and executive functions (EF) as predictors of peer victimization in three groups: high-functioning adolescent boys with an Autism Spectrum Disorder (ASD) (n = 30); typically developing adolescent boys (n = 40); and adolescent boys (n = 22) without ASD with special education needs (SN). Controlling for age and bullying others, regression analyses revealed EF as measured by the Behavior Rating Inventory of Executive Functioning (Gioia et al., 2000) to be a significant predictor across all types of peer victimization (physical, social, and verbal) regardless of group membership. It is concluded that EF may play a pivotal role in explaining why some SN adolescents with and without ASD are at-risk for peer victimization.     

The experience of friendship,victimization and bullying in children with an autism spectrum disorder: Associations with child characteristics and school placement

Children with an autism spectrum disorder (ASD) may be vulnerable to social isolation and bullying. We measured the friendship, fighting/bullying and victimization experiences of 10–12-year-old children with an ASD (N = 100) using parent, teacher and child self-report. Parent and teacher reports were compared to an IQ-matched group of children with special educational needs (SEN) without ASD (N = 80) and UK population data. Parents and teachers reported a lower prevalence of friendships compared to population norms and to children with SEN without an ASD. Parents but not teachers reported higher levels of victimization than the SEN group. Half of the children with an ASD reported having friendships that involved mutuality. By teacher report children with an ASD who were less socially impaired in mainstream school experienced higher levels of victimization than more socially impaired children; whereas for more socially impaired children victimization did not vary by school placement. Strategies are required to support and improve the social interaction skills of children with an ASD, to enable them to develop and maintain meaningful peer friendships and avoid victimization.     

Psychiatric symptoms in children and adolescents with higher functioning autism spectrum disorders on the Development and Well-Being Assessment

The Development and Well-Being Assessment (DAWBA) parent interview was used to assess psychiatric symptoms in children and adolescents with higher functioning autism spectrum disorders (ASD) (n = 60; age range 6.5–16.7) and in typically developing (TD) children and adolescents (n = 60; age range 6.9–16.2). Psychiatric symptoms were reported in the ASD group (68%) significantly more compared to the TD group (12%). Specifically, emotional disorders, attention deficit hyperactivity disorder/hyperkinesis, and tic disorders were significantly more frequent in the ASD group compared to the TD group. Routine screening and early identification of these symptoms could have important implications for planning interventions and thus outcome in individuals with higher functioning ASD. The DAWBA would be a useful interview for this purpose, since it can also be easily and quickly administered in clinics not specialized in psychiatry.     

The link between emotion regulation,social functioning,and depression in boys with ASD

PurposeSymptoms of depression are common in children and adolescents with an autism spectrum disorder (ASD), but information about underlying developmental factors is limited. Depression is often linked to aspects of emotional functioning such as coping strategies, but in children with ASD difficulties with social interactions are also a likely contributor to depressive symptoms.MethodologyWe examined several aspects of emotional coping (approach, avoidant, maladaptive) and social functioning (victimization, negative friendship interactions) and their relation to depression symptoms in children with ASD (N = 63) and typically developing (TD) peers (N = 57). Children completed a battery of self-report questionnaires.ResultsLess approach and avoidant, but more maladaptive coping strategies, and poor social functioning were uniquely associated with more symptoms of depression in children with ASD. Only less approach and more maladaptive coping were uniquely associated with depression severity in TD boys.ConclusionsUnlike TD boys, boys with ASD who report using avoidant strategies to deal with stressful situations report fewer symptoms of depression, suggesting that this may be an adaptive emotion regulation strategy. However, understanding the role of over-arousal in this process, inferences about long-term effects of this strategy, its causality and direction of effects will require additional research.     

Effects of eye gaze directions of facial images on looking behaviour and autonomic responses in adolescents with autism spectrum disorders

It has been suggested that atypical eye contact of individuals with autism spectrum disorders (ASDs) arises from an unusually high level of autonomic activity elicited by another person's gaze. The present study investigated visual fixation duration and autonomic reactivity (heart rate, skin conductance response) simultaneously, while adolescents looked towards photographs of neutral faces, with either direct eye gaze, averted eye gaze or closed eyes. Both cognitively able adolescents with ASD (n = 31, mean age = 16 years, mean IQ = 104) and typically developing (TD) adolescents (n = 34, mean age = 16 years, mean IQ = 108) looked significantly longer towards the eye region of faces with direct eye gaze compared with faces with averted eye gaze or closed eyes. The adolescents with ASD did not show higher levels of autonomic activity than TD adolescents while they were instructed to look at the eye region. This suggests that looking at the eye region of static faces does not particularly trigger high autonomic arousal in adolescents with ASD.     

Postural sway patterns in children with autism spectrum disorder compared with typically developing children

Postural control is a fundamental building block of each child's daily activities. The aim of this study was to compare patterns of postural sway in children with autism spectrum disorder (ASD) with typically developing children (TD). We recruited 21 schoolchildren diagnosed with ASD aged 9–14 and 30 TD pupils aged 8–15. Postural sway parameters in composite, anteroposterior and mediolateral axis were reported. Furthermore we examined the impact of age and characteristics of autism on postural sway. Children with ASD exhibited higher amount of sway in anteroposterior range (p < 0.001), mediolateral range (p = 0.002), root mean square (p = 0.001), mean velocity (p = 0.03), and sway area (p = 0.007) compared with their TD peers. Children with ASD showed higher instability in mediolateral than anteroposterior axis though TD children demonstrated higher sway scores in anteroposterior than mediolateral direction. The rate of autism symptom severity significantly affected the postural sway in children with ASD (p < 0.05). In conclusion, patterns of postural control seem to be different in children with ASD compared with TD counterparts. This could be partially due to clinical features were underlying in ASD.     

Results of an Italian school-based expressive writing intervention trial focused on peer problems

This study investigated the effectiveness of an expressive writing intervention in a sample of Italian early adolescents on internalizing and post-traumatic stress symptoms and coping strategies. Participants were 153 Italian adolescents (48% male), attending 7th grade (M = 12.24 yrs, SD = 0.47). Youth were randomly assigned either to write about personal emotional events related to problems they recently experienced with peers, or trivial topics. Data were collected before and 2 months following the intervention. Analyses revealed no overall intervention effects on symptoms. However, level of peer victimization moderated the effects of the intervention on coping strategies, such that victimized youth in the intervention showed increases in cognitive restructuring and avoidance coping, relative to other groups. Thus, expressive writing affected coping strategies but not internalizing problems in our early adolescent sample.     

The effect of peer- and sibling-assisted aquatic program on interaction behaviors and aquatic skills of children with autism spectrum disorders and their peers/siblings

The purpose of this study was to assess the effect of peer- and sibling-assisted learning on interaction behaviors and aquatic skills in children with autism spectrum disorders (ASD). Outcome measures were also examined in their typically developing (TD) peers/siblings. Twenty-one children with ASD and 21 TD children were assigned in three groups: peer-assisted (PG), sibling-assisted (SG), and control (CG). All participated in 16-week aquatic settings under three instructional conditions (teacher-directed, peer/sibling-assisted, and voluntary support). The main findings were that (a) PG and SG of children with ASD showed significantly more improvement on physical and social interactions with their TD peers/siblings during peer/sibling-assisted condition as compared to CG (p < 0.01), (b) PG and SG of children with ASD showed significantly more improvement on physical interactions with their TD peers/siblings (p < 0.01) and social interactions with their teachers and other children with ASD (p < 0.01) during voluntary support condition as compared to CG, and (c) all children with ASD and their TD peers/siblings significantly increased their aquatic skills after the program. The benefit for children with ASD as well as TD peers/siblings makes the use of TD peer/sibling assisted learning an even more desirable instructional strategy.     

Physical activity during the segmented school day in adolescents with and without autism spectrum disorders

The purpose of this study was to assess the intensity of physical activity (PA) that secondary school-aged students with autism spectrum disorders (ASD) and typically developing (TD) students exert during a school day, and to compare the percentages of students achieving the recommended guidelines between groups. The PA of 60 male students (ASD, n = 30; TD, n = 30) was recorded every 10 s for up to 5 school days by performing uniaxial accelerometry. The main results are listed as follows: (a) daily PA was significantly lower among the students with ASD than among the TD students; (b) students with ASD spent significantly lower proportion of their time in moderate PA than TD students did during physical education (PE), recess, and lunchtime; and (c) fewer students with ASD than TD students achieved the PA guidelines during the school day and PE time. Schools should increase PA opportunities across the school day.     

Anthropometric measures of Spanish children with autism spectrum disorder

We aimed to compare body mass index (BMI) and healthy eating index (HEI) in children with autism spectrum disorder (ASD, n = 105) and typically developing (TD, n = 495) children. They were aged 6–9 years, lived in Valencia (Spain) and came from similar cultural and socio-economic backgrounds. In this case–control study, the weight, height and BMI were measured for both groups. Three-day food records were used to assess dietary intake. Although the differences between children with ASD and TD children in raw BMI (p = 0.44), BMI z-score (p = 0.37), HEI (p = 0.43) and total energy intake (p = 0.86) were not significant, children with ASD and the boys subgroup were shorter (p = 0.01), but not the girls subgroup, compared to TD children of the same gender. Using the controls values as a reference, the BMI distribution in children with ASD became distorted, with values below the 5th percentile (11% vs. 4%, p = 0.03) and above the 95th percentile (8% vs. 5%, p = 0.04). The gender- and age-adjusted odds ratios for being underweight in the groups of all children and boys with ASD were 3.03 and 2.39, respectively, vs. TD children. Our data suggest that routine monitoring of children with ASD should include anthropometric measurements and assessment of their dietary habits.     

Physical activity and self-determined motivation of adolescents with and without autism spectrum disorders in inclusive physical education

The main purpose of this study was to compare the objectively measured physical activity (PA) and the motivation process between adolescents with (n = 25) and without (n = 75) autism spectrum disorders (ASD) in inclusive physical education (PE); and assess the associations of the PA levels to a sequence of motivational processes. Independent t-tests revealed significant PA and motivational process differences between adolescents with and without ASD. External regulation was positively correlated with the percentage of time that adolescents with ASD spent in moderate PA (r₂₅ = 0.58, p < .01) and moderate-to-vigorous PA (r₂₅ = 0.50, p < .05), and this extrinsic motive was associated with their needs of being attached or related in the class (r₂₅ = 0.53, p < .01). No significant associations of PA in PE on the motivational sequences of adolescents without ASD were observed. It is concluded that adolescents with ASD had less PA levels in PE and lower motives toward PE than adolescents without ASD, and external regulation was important in facilitating PA participation in adolescents with ASD.     

Empathic accuracy in adolescents with autism spectrum disorders and adolescents with attention-deficit/hyperactivity disorder

In research on theory of mind (ToM) in individuals with an autism spectrum disorder (ASD) mainly static mind-reading tasks were used. In this study both a static (Eyes Test) and a more naturalistic (empathic accuracy task) ToM measure were used to investigate the perspective taking abilities of adolescents with ASD (n = 13), adolescents with attention-deficit/hyperactivity disorder (ADHD; n = 13) and typically developing adolescents (n = 18). An innovative aspect concerns the standard stimulus tapes of the empathic accuracy task, which showed interactions between dyads of one adolescent with ADHD and one adolescent without ADHD. In this way, we were able to compare the ‘readability’ of the thoughts and feelings of adolescents with and without ADHD. The results clearly demonstrate the impairment in perspective taking abilities of adolescents with ASD, both on the static and naturalistic mind-reading task. Moreover, the empathic accuracy task seems to be a useful and promising method to assess ToM abilities in adolescents, with or without clinical problems. Finally, thoughts and feelings of target persons with ADHD seemed to be less easy to read than the thoughts and feelings of typically developing target persons.     

A comparison of tantrum behavior profiles in children with ASD,ADHD and comorbid ASD and ADHD

The present study was conducted to compare rates of tantrum behaviors in children with autism spectrum disorders (ASD) (n = 255), attention-deficit/hyperactivity disorder (ADHD) (n = 40) and children with comorbid ASD and ADHD (n = 47). Parents/guardians of children aged 3–16 years were surveyed about their children's behaviors using the Autism Spectrum Disorders-Comorbidity for Children (ASD-C-C). Children with ADHD alone differed from children with ASD alone and children with comorbid ASD and ADHD on rates of tantrum behaviors. Examination of individual tantrum behavior items indicated that children with comorbid ASD and ADHD have a more similar symptom presentation to children with ASD than children with ADHD. This study adds to the literature on the presentation of common co-occurring behaviors of ASD when there is comorbid ADHD. The implications of these findings may aid in the assessment and treatment of tantrum behaviors in children with comorbid ASD and ADHD.     

Increased clinical and neurocognitive impairment in children with autism spectrum disorders and comorbid bipolar disorder

Bipolar (BD) symptomatology is prevalent in children with autism spectrum disorders (ASD) and may lead to increased impairment. The current study compared clinical and neurocognitive impairment in children (7–13 years) diagnosed with ASD (n = 55), BD (n = 34), ASD + BD (n = 23), and a non-clinical control group (n = 27). Relative to the ASD group, the ASD + BD group reported elevated rates of aggression and delinquency, behavioral disorders, depression, obsessive-compulsive disorder, and suicidal ideation, and poorer performance on the Stroop Color-Word Test. Future research might address how best to improve diagnostic assessment and adapt treatment to meet the needs of this uniquely impaired population.     

Psychometric properties of the French Version of the Social Responsiveness Scale in autism spectrum disorder with or without attention deficit hyperactivity disorder

ObjectivesThe Social Responsiveness Scale (SRS) is an instrument that is commonly used to screen for Autism Spectrum Disorder (ASD). Attention Deficit Hyperactive Disorder (ADHD) frequently occurs with ASD and both disorders share some phenotypic similarities. In the present study, we aimed to determine the psychometric properties of the French version of the Social Responsiveness Scale (SRS) and its 5 subscales (social awareness, social cognition, social communication, social motivation, and autistic mannerisms) to discriminate between children with ADHD and those with ASD (differential diagnosis) and children with ADHD from those with a dual diagnosis of ADHD and ASD (comorbid diagnosis).MethodSRS total scores and the 5 subscores of the SRS were compared between 4 groups of children: ADHD (n = 32), ASD + ADHD (n = 30), ASD (n = 31) and typical neurodevelopment (TD; n = 30) children. The discriminant validity was estimated using the Area Under the ROC Curves (AUC).ResultsSRS Social cognition (AUC = 0.73) and Autistic mannerisms (AUC = 0.70) subscores were the most discriminating for differential diagnosis of ASD and ADHD. SRS total scores (AUC = 0.70), and Social communication (AUC = 0.66) and Autistic mannerisms (AUC = 0.75) subscores were the most discriminating for comorbid diagnosis of ASD among ADHD children.ConclusionThe SRS autistic mannerisms subscore was found to be clinically relevant for both differential diagnosis of ASD and ADHD and comorbid diagnoses of ASD among ADHD children but with a modest discriminant power.     

Inattention and hyperactivity in association with autism spectrum disorders in the CHARGE study

BackgroundAttention deficits in young children with autism spectrum disorder (ASD) are not well understood. This study sought to determine: 1) the prevalence of ADHD symptoms in young children with ASD, typical development (TD), and developmental delay (DD) and 2) the association between ADHD symptoms and cognitive and behavioral functioning in children with ASD.MethodADHD symptoms, defined according to Aberrant Behavior Checklist (ABC) hyperactivity subscale scores, were compared across children aged 2–5 from a large case-control study with ASD (n = 548), TD (n = 423), and DD (n = 180). Inattention and hyperactivity items within this subscale were also explored. Within the ASD group, linear and logistic regression were used to examine how ADHD symptoms were associated with cognition as assessed by the Mullen Scales of Early Learning and adaptive functioning as assessed by the Vineland Adaptive Behavior Scales.ResultsMean hyperactivity subscale scores were lowest in children with TD (mean = 3.19), higher in children with DD (12.3), and highest in children with ASD (18.2; between-group p < 0.001). Among children with ASD, significant associations were observed with higher ADHD symptoms and poorer adaptive and cognitive functioning (adjusted beta for hyperactivity score in association with: Vineland composite = −5.63, p = 0.0005; Mullen visual reception scale = −2.94, p = 0.02; for the highest vs. lowest quartile of hyperactivity score, odds of lowest quintile of these scores was approximately doubled). Exploratory analyses highlighted associations with inattention-related items specifically.ConclusionThese results suggest ADHD symptoms may play a key role in the functioning of young children with ASD.     

Do spoken nonword and sentence repetition tasks discriminate language impairment in children with an ASD?

The primary aim of this paper was to investigate heterogeneity in language abilities of children with a confirmed diagnosis of an ASD (N = 20) and children with typical development (TD; N = 15). Group comparisons revealed no differences between ASD and TD participants on standard clinical assessments of language ability, reading ability or nonverbal intelligence. However, a hierarchical cluster analysis based on spoken nonword repetition and sentence repetition identified two clusters within the combined group of ASD and TD participants. The first cluster (N = 6) presented with significantly poorer performances than the second cluster (N = 29) on both of the clustering variables in addition to single word and nonword reading. The significant differences between the two clusters occur within a context of Cluster 1 having language impairment and a tendency towards more severe autistic symptomatology. Differences between the oral language abilities of the first and second clusters are considered in light of diagnosis, attention and verbal short term memory skills and reading impairment.     

Why do young adolescents bully? Experience in Malaysian schools

IntroductionTo determine sociodemographic and psychological factors associated with bullying behavior among young adolescents in Malaysia.MethodsThis is a cross-sectional study of four hundred ten 12-year-old adolescents from seven randomly sampled schools in the Federal Territory of Kuala Lumpur, Malaysia. Sociodemographic features of the adolescents and their parents, bullying behavior (Malaysian Bullying Questionnaire), ADHD symptoms (Conners Rating Scales), and internalizing and externalizing behavior (Child Behaviour Checklist) were obtained from adolescents, parents and teachers, respectively.ResultsOnly male gender (OR = 7.071, p = 0.01*, CI = 1.642–30.446) was a significant sociodemographic factor among bullies. Predominantly hyperactive (OR = 2.285, p = 0.00*, CI = 1.507–3.467) and inattentive ADHD symptoms reported by teachers (OR = 1.829, p = 0.03*, CI = 1.060–3.154) and parents (OR = 1.709, p = 0.03*, CI = 1.046–2.793) were significant risk factors for bullying behavior while combined symptoms reported by young adolescents (OR = 0.729, p = 0.01*, CI = 0.580–0.915) and teachers (OR = 0.643, p = 0.02*, CI = 0.440–0.938) were protective against bullying behavior despite the influence of conduct behavior (OR = 3.160, p = 0.00*, CI = 1.600–6.241). Internalizing behavior, that is, withdrawn (OR = 0.653, p = 0.04*, CI = 0.436–0.977) and somatic complaints (OR = 0.619, p = 0.01*, CI = 0.430–0.889) significantly protect against bullying behavior.DiscussionsRecognizing factors associated with bullying behavior, in particular factors distinctive to the local population, facilitates in strategizing effective interventions for school bullying among young adolescents in Malaysian schools.     

Rates of psychotropic medication use in children with ASD compared to presence and severity of problem behaviors

There is a scarcity of research on the relationship between presence of problem behaviors and psychotropic medication use in children with autism spectrum disorder (ASD). Participants in the current study were children and adolescents ages 3–17 years who were sorted into four groups: ASD on psychotropic medication (N = 100), ASD not on psychotropic medication (N = 147), typically developing on medication (N = 48), and typically developing not on medication (N = 168). A one-way multivariate analysis of covariance (MANCOVA) was conducted to determine the relationship between medication use and rates of internalizing and externalizing behaviors. Post hoc analyses revealed that children with ASD on psychotropic medication evinced significantly more externalizing behaviors than children with ASD not on medication. However, the two groups did not significantly differ on rates of internalizing behaviors. These results suggest that psychotropic medications may often be prescribed to manage externalizing behaviors. Implications of these findings are discussed in relation to the existing literature.     

Role of parental occupation in autism spectrum disorder diagnosis and severity

Some have suggested that parents of children with autism spectrum disorder (ASD) may present with less recognizable autistic-like phenotypic characteristics, leading them to highly systemizing occupations. Using secondary analysis of data from two previous studies of children with ASD, we tested associations between parental occupations and ASD diagnosis and the association of parental occupational characteristics on ASD severity. We found that fathers in healthcare (P < 0.01) and finance (P = 0.03) were more likely to have children with ASD. Additionally, joint effects of parental technical occupations were associated with communication (P < 0.01) and social impairment (P = 0.04). These results support that a “broader phenotype” and possible assortative mating in adults with autistic-like characteristics might contribute to intergenerational transmission and having offspring with greater ASD severity.
