Emotional and Behavioral Adjustment in Typically Developing Siblings of Children with Autism Spectrum Disorders

Research findings describing the emotional and behavioral functioning of typically developing (TD) siblings of children with autism spectrum disorders (ASD) are contradictory. Methodological issues, such as small study sample sizes and reliance on parent report, may contribute to inconsistent findings. The purpose of this study was to use parent and teacher report to describe presence of internalizing and externalizing behaviors among a large sample (n = 486) of TD siblings of children with ASD. Results indicated that siblings did not exhibit a disproportionate prevalence of internalizing or externalizing symptoms in comparison to the standardization sample of the rating scale. The presence of a sibling with an ASD may not be considered a risk-factor for adjustment problems among TD siblings.     

Predicting Social Impairment and ASD Diagnosis in Younger Siblings of Children with Autism Spectrum Disorder

Later-born siblings of children with autism spectrum disorder (Sibs-ASD) are at elevated risk for social impairments. Two putative predictors of later social impairment—measures of responding to joint attention and weighted triadic communication—were examined in a sample of 43 Sibs-ASD who were followed from 15 to 34 months of age. Results revealed that initial level of responding to joint attention and growth rate of weighted triadic communication predicted the degree of social impairment at the final measurement period. Additionally, both predictors were associated with later ASD diagnosis. In contrast, unweighted triadic communication, age of entry into the study, and initial language level did not predict later social impairment. The importance of considering social outcome as a continuous variable in prospective studies of Sibs-ASD is discussed.     

Comparison Among Children with Children with Autism Spectrum Disorder, Nonverbal Learning Disorder and Typically Developing Children on Measures of Executive Functioning

It has been suggested that children with nonverbal learning disabilities (NLD) or Asperger’s Syndrome (AS) may show difficulties with executive functioning. There were 3 groups in this study who completed a neuropsychological battery of visual-spatial, executive functioning, and reasoning tasks; AS (n = 37), NLD (n = 31), and controls (n = 40). Results indicated that children in both clinical groups scored within average limits on measures of spatial reasoning and verbal ability. Fluid reasoning was also found to be within average ranges for all groups. The AS group experienced significant problems with cognitive flexibility compared to the other two groups. In contrast the NLD group showed fewer difficulties with cognitive flexibility but more problems with visual sequencing. These findings suggest that performance on executive function measures for children with AS or NLD is remarkably similar with subtle differences present.     

Autonomic Arousal to Direct Gaze Correlates with Social Impairments Among Children with ASD

The present study investigated whether autonomic arousal to direct gaze is related to social impairments among children with autism spectrum disorder (ASD). Arousal was measured through skin conductance responses (SCR) while the participants (15 children with ASD and 16 control children) viewed a live face of another person. Impairments in social skills was assessed with the Developmental, Dimensional and Diagnostic Interview. The level of arousal enhancement to direct gaze in comparison to arousal to faces with averted gaze or closed eyes was positively associated with impairments in social skills (use of language and other social communication skills and use of gesture and non-verbal play) among children with ASD. There was no similar association among children without ASD. The role of arousal-related factors in influencing eye contact behaviour in ASD is discussed.     

Co-segregation of Social Cognition, Executive Function and Local Processing Style in Children with ASD, their Siblings and Normal Controls

Cognitive research proposes that social cognition (SC), executive functions (EF) and local processing style (weak CC) may be fruitful areas for research into the familial-genetic underpinnings of Autism Spectrum Disorders (ASD). The performance of 140 children with ASD, 172 siblings and 127 controls on tasks measuring SC (face recognition, affective prosody, and facial emotion recognition), EF (inhibition, cognitive flexibility, and verbal working memory) and local processing style was assessed. Compelling evidence was found for the interrelatedness of SC and EF, but not local processing style, within individuals and within families, suggesting that these domains tend to co-segregate in ASD. Using the underlying shared variance of these constructs in genetic research may increase the power for detecting susceptibility genes for ASD.     

Feeding and Eating Behaviors in Children with Autism and Typically Developing Children

Mothers of children aged 2–12 years completed an exhaustive questionnaire assessing feeding and eating behaviors for both themselves and their children with autism, and typically developing siblings of children with Autism Spectrum Disorder (where available), or typically developing children with no sibling with a disability. Results indicate that children with autism were only marginally more likely to exhibit picky eating behavior (overall style) than their siblings or matched typically developing children. Rates of ritualistic feeding behaviors were equivalent in all groups of children although children with autism were more likely to be currently exhibiting problematic eating and feeding behaviors. The implications of these results for the treatment of feeding difficulties exhibited by children with autism will be discussed.

Increased Sensory Processing Atypicalities in Parents of Multiplex ASD Families Versus Typically Developing and Simplex ASD Families

Recent studies have suggested that sensory processing atypicalities may share genetic influences with autism spectrum disorder (ASD). To further investigate this, the adolescent/adult sensory profile (AASP) questionnaire was distributed to 85 parents of typically developing children (P-TD), 121 parents from simplex ASD families (SPX), and 54 parents from multiplex ASD families (MPX). After controlling for gender and presence of mental disorders, results showed that MPX parents significantly differed from P-TD parents in all four subscales of the AASP. Differences between SPX and MPX parents reached significance in the Sensory Sensitivity subscale and also in subsequent modality-specific analyses in the auditory and visual domains. Our finding that parents with high genetic liability for ASD (i.e., MPX) had more sensory processing atypicalities than parents with low (i.e., SPX) or no (i.e., P-TD) ASD genetic liability suggests that sensory processing atypicalities may contribute to the genetic susceptibility for ASD.     

Early Word Reading of Preschoolers with ASD,Both With and Without Hyperlexia,Compared to Typically Developing Preschoolers

A portion of children with Autism Spectrum Disorder (ASD) exhibit a strength in early word reading referred to as hyperlexia (HPL), yet it remains unclear what mechanisms underlie this strength. Typically developing children (TD) acquire phonological awareness, alphabet knowledge and language skills as precursors to word reading. We compared these skills across English-speaking preschoolers with ASD, both with and without hyperlexia, and TD preschoolers. Findings indicated that the group with both ASD and HPL (ASD?+?HPL) exhibited advanced word reading and letter naming skills as compared to the other two groups, but did not demonstrate commensurate phonological awareness, letter-sound correspondence, or language skills. Findings support an alternative, non-phonological approach to early word reading in preschoolers with ASD and hyperlexia.

     

Dietary Patterns and Body Mass Index in Children with Autism and Typically Developing Children

To determine whether dietary patterns (juice and sweetened non-dairy beverages, fruits, vegetables, fruits and vegetables, snack foods, and kid's meals) and associations between dietary patterns and body mass index (BMI) differed between 53 children with autism spectrum disorders (ASD) and 58 typically developing children, ages 3-11, multivariate regression models including interaction terms were estimated. Children with ASD were found to consume significantly more daily servings of sweetened beverages (2.6 versus 1.7, p = 0.03) and snack foods (4.0 versus 3.0, p = 0.01) and significantly fewer daily servings of fruits and vegetables (3.1 versus 4.4, p = 0.006) than typically developing children. There was no evidence of statistical interaction between any of the dietary patterns and BMI z-score with autism status. Among all children, fruits and vegetables (p = 0.004) and fruits alone (p = 0.005) were positively associated with BMI z-score in our multivariate models. Children with ASD consume more energy-dense foods than typically developing children; however, in our sample, only fruits and vegetables were positively associated with BMI z-score.     

Priming the Meaning of Homographs in Typically Developing Children and Children with Autism

Two explanations for deficits underlying autism were tested: weak central coherence (WCC) and executive dysfunction. Consistent with WCC, Happé (British Journal of Developmental Psychology 15 (1997) 1) found that children with autism failed to use sentence context in pronouncing homographs. In an alternate approach, we investigated whether children with autism can use meanings of related word primes. We presented children with autism and controls with primes for homographs, semantically related, and unrelated targets. Children with autism used primes to correctly pronounce homographs upon first presentation but showed difficulty inhibiting prior responses upon later presentation of the homographs with different primes. Children with autism also showed semantic priming effects. We conclude that children with autism do not show an absolute deficit in ability to use contextual information.     

Friendship and Internalizing Symptoms Among Children and Adolescents with ASD

Anxiety and depression are common among children and adolescents with autism spectrum disorders (ASD), highlighting a need to identify factors that protect against these symptoms. Among typically developing children, friendships are protective, and lead to better emotional outcomes. The current study examined a large, well-characterized sample of children and adolescents with ASD to examine the relations among friendship, ASD symptom severity, and anxiety/depression. Rates of anxiety/depression were high in this sample. Greater ASD severity was associated with fewer symptoms of anxiety/depression, lower IQ, and poorer number and/or quality of reciprocal friendships. Surprisingly, children with no or very poor dyadic relationships experienced less anxiety than those with existing, but limited, friendships. Implications and directions for future research are discussed.     

Theory of Mind, Socio-Emotional Problem-Solving, Socio-Emotional Regulation in Children with Intellectual Disability and in Typically Developing Children

This study has examined the link between social information processing (SIP) and socio-emotional regulation (SER) in 45 children with intellectual disability (ID) and 45 typically developing (TD) children, matched on their developmental age. A Coding Grid of SER, focusing on Emotional Expression, Social Behaviour and Behaviours towards Social Rules displayed by children in three dyadic contexts (neutral, competitive or cooperative) was applied. Correlational analyses highlighted specific “bi-directional” links between some abilities in SIP and in SER, presenting between-groups partial similarities and dissimilarities that allowed discussing the developmental delay versus difference hypotheses in ID children. Cluster cases analyses identified subgroups with variable patterns of links. In both groups, the SIP and some categories of SER varied depending on developmental age.     

Parent-Reported Temperament Trajectories Among Infant Siblings of Children with Autism

Temperament atypicalities have been documented in infancy and early development in children who develop autism spectrum disorders (ASD). The current study investigates whether there are differences in developmental trajectories of temperament between infants and toddlers with and without ASD. Parents of infant siblings of children with autism completed the Carey Temperament Scales about their child at 6, 12, 18, 24, and 36 months of age. Temperament trajectories of children with ASD reflected increases over time in activity level, and decreasing adaptability and approach behaviors relative to high-risk typically developing (TD) children. This study is the first to compare temperament trajectories between high-risk TD infants and infants subsequently diagnosed with ASD in the developmental window when overt symptoms of ASD first emerge.     

Trait Emotional Intelligence and Problematic Social Media Use Among Adults: The Mediating Role of Social Media Use Motives

There are many contributing factors to problematic social media use including personality differences, psychosocial factors, and specific use motivations. The present study (N = 444 emerging adults, 75% women) investigated the direct and indirect relationships between trait emotional intelligence and problematic social media use via social media use motives by testing a complex mediation model. Path analyses suggested that trait emotional intelligence was directly and indirectly associated with problematic social media use via two social media use motives: (i) expressing or presenting a more popular self, and (ii) passing time. Results of the present study indicate that trait emotional intelligence may have a role in the motives for using social media as well as the development and maintenance of problematic social media use. Moreover, future studies should focus mediator risk factors between trait emotional intelligence and problematic social media use.

     

Objective Sleep Measurement in Typically and Atypically Developing Preschool Children with ADHD-Like Profiles

Objective This study investigated the association between preschool children’s sleep patterns measured by actigraphy and parent-reported hyperactivity symptoms. Many previous studies have reported sleep problems in children with attention deficit hyperactivity disorder (ADHD)-like symptoms. Methods This study examined a cross-sectional sample of 186 preschoolers age 2–5 years in three groups: children with autism, children with developmental delay without autism, and typically developing children recruited from the general population. One week of actigraphic sleep data plus a parent report of the presence or absence of a current sleep problem were collected. Parents completed the child behavior checklist; a subset of children in preschool had teachers who completed the caregiver-teacher report form. Sleep behavior was compared for those children with and without clinical levels of attention-deficit/hyperactivity symptoms (T scores ≥65). Results The prevalence of a parent-defined sleep problem across the entire sample was 36.1%. Thirty-four percent of the sample had a parent-reported ADHD composite in the clinical range. Those children with a clinical ADHD profile were more likely to be described by parents as having a sleep problem. However, no significant differences in actigraphic sleep patterns or night-to-night sleep-wake variability were found for children with an ADHD profile in the clinical range. Conclusions In this non-clinical sample of preschool age children, parental reports of clinical ADHD profiles were significantly associated with parental reports of sleep problems but not with actigraphically recorded sleep-wake data.     

Joint-Attention and the Social Phenotype of School-Aged Children with ASD

The validity of joint attention assessment in school-aged children with ASD is unclear (Lord, Jones, Journal of Child Psychology and Psychiatry 53(5):490–509, 2012). This study examined the feasibility and validity of a parent-report measure of joint attention related behaviors in verbal children and adolescents with ASD. Fifty-two children with ASD and 34 controls were assessed with the Childhood Joint Attention Rating Scale (C-JARS). The C-JARS exhibited internally consistency, α = 0.88, and one factor explained 49% of the scale variance. Factor scores correctly identified between 88 and 94% of the children with ASD and 62–82% of controls. These scores were correlated with the ADOS-2, but not other parent-report symptom measures. The C-JARS appears to assess a unique dimension of the social-phenotype of children with ASD.
