Fundamental frequency development in typically developing infants and infants with severe‐to‐profound hearing loss

Little research has been conducted on the development of suprasegmental characteristics of vocalizations in typically developing infants (TDI) and the role of audition in the development of these characteristics. The purpose of the present study was to examine the longitudinal development of fundamental frequency (F₀) in eight TDI and eight infants with severe‐to‐profound hearing loss matched for level of vocal development. Results revealed no significant changes in F₀ with advances in pre‐language vocal development for TDI. Infants with hearing loss, however, showed a statistically reliable higher variability of F₀ than TDI, when age was accounted for as a covariate. The results suggest development of F₀ may be strongly influenced by audition.     

Brief Report: Fathers’ and Mothers’ Ratings of Behavioral and Emotional Problems in Siblings of Children with Autism Spectrum Disorder

Debate is ongoing about whether typically developing siblings of children with autism spectrum disorder (ASD) are at greater risk of behavioral or emotional problems than siblings of children without ASD. Most data on behavior is provided by mothers, and we do not know whether fathers’ reports differ. The strengths and difficulties questionnaire (Goodman in J Child Psychol Psychiatry 38(5):581–586, 1997) was completed by 168 mothers and 130 fathers. Parents were more likely to rate siblings as having ‘abnormal’ behavior when compared to a normative population. We found moderate correlations between mother–father ratings. More research may be needed to understand any clinical benefits of gathering data about sibling adjustment from more than one parent in the family. Implications for clinical practice and future research are discussed.     

Stakeholders’ perspectives on social participation in preschool children with Autism Spectrum Disorder

Objective: To determine (a) the essential components of social participation for preschool children with Autism Spectrum Disorder (ASD) using stakeholders’ perspectives and (b) the facilitators and barriers experienced in promoting social participation. Methods: A mixed-methods, web-based survey utilizing the International Classification of Functioning, Disability and Health – Child and Youth version (ICF-CY) taxonomy was circulated across Canada through purposeful snowball sampling. Results: Frequency analysis of the combined responses of 74 stakeholders revealed the most essential components of social participation were: (a) behavior management, (b) social interactions, and (c) various types of play. Further, content analysis revealed that stakeholders used intrinsic motivation strategies and contingency management to facilitate social participation. Conclusion: Stakeholders reported that the purpose of social participation was to engage the child in fun, enjoyable social activities that developed relationships between the child and peers and created a sense of belonging in the community.     

How are parental reactions to children’s emotions linked with Theory of Mind in children with Autism Spectrum Disorder?

BackgroundBased on the model of ‘Parental Socialization of Emotions’ (Eisenberg, Cumberland, & Spinrad, 1998), these studies examined the profiles of parental reactions to their children’s emotions and the relation between these reactions and their ASD children’s ToM abilities. They could help identify protective versus risk factors in their ToM development.MethodThe participants in Study 1 included 29 mothers and 29 fathers of ASD children (26 boys and 3 girls). In Study 2, 39 mothers and 31 fathers and their ASD children participated. In both studies, mothers and fathers independently completed a questionnaire about their reactions to their children’s emotions. In Study 2 only, children’s ToM abilities were assessed by means of direct measures and a questionnaire completed by parents.ResultsThe results indicated that mothers displayed more encouragement and less minimizing responses to their ASD children’s negative emotions than fathers. For both maternal and paternal model analysed by stepwise regressions, the results highlighted specific links between each parent’s reactions and children’s ToM abilities that varied according to mental states. These findings suggested that parental reactions which help the children to understand how they can solve problems are protective factors, while parental reactions which deprive children of an opportunity to explore their feelings are risk factors.ConclusionThese studies provide new information about how parental reactions to children’s emotions could socialise ASD children’s ToM abilities better; this could be useful for adapting parental support programmes.     

Comparing Acquisition of AAC-Based Mands in Three Young Children with Autism Spectrum Disorder Using iPad® Applications with Different Display and Design Elements

Augmentative and alternative communication (AAC) applications may differ in their use of display and design elements. Using a multielement design, this study compared mand acquisition in three preschool-aged males with autism spectrum disorder, across three different displays in two iPad^® AAC applications. Displays included a Widgit symbol button (GoTalk), a photographical hotspot (Scene and Heard), and a Widgit symbol button along with a photograph (Scene and Heard). Applications had additional design differences. Two participants showed more rapid and consistent acquisition with the photographical hotspot than with the symbol button format, but did not master the combined format. The third participant mastered all three conditions at comparable rates. Results suggest that AAC display and design elements may influence mand acquisition.     

Grandparents’ Experience of Autism Spectrum Disorder: Identifying Primary Themes and Needs

Limited information is available regarding the first person perspective of grandparents of children with Autism Spectrum Disorders (ASD). In the present study, 1870 grandparents of a child with ASD participated in a nationwide, online, anonymous, 30-minute survey and responded to open-ended questions including their “greatest challenges and greatest joys” as the grandparent of a child on the autism spectrum. A grounded theory approach to qualitative analysis revealed four overarching categories: a Desire for Connection, Barriers to Care, Celebration of Progress, and Personal Reactions. Despite the presence of significant challenges grandparents often experienced positivity in their role, and engaged in radical acceptance of their grandchild as well as transformative insight and advocacy. Specific recommendations are offered to help address grandparents’ needs and capitalize upon their resilience.     

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.     

Impaired theory of mind and symptoms of Autism Spectrum Disorder in children with Prader–Willi syndrome

In order to evaluate the social cognitive functioning in children with Prader–Willi syndrome (PWS), Theory of Mind (ToM) and symptoms of Autism Spectrum Disorder were evaluated. Sixty-six children with PWS aged 7–17 years were tested using the Theory of Mind test-R and the Diagnostic Interview for Social Communication disorders. We tested the correlation between Total ToM Standard Deviation Score (Total ToM SDS) and genetic subtype of paternal deletion or maternal uniparental disomy, and total IQ, verbal IQ and performal IQ. Prevalence and symptoms of Autism Spectrum Disorder were assessed. Median (interquartile range) of total ToM SDS of those aged 7–17 years was ?3.84 (?5.73, ?1.57). Their Total ToM SDS correlated with total IQ (β = 0.662, p < 0.001, adj.R² = 0.407), in particular with verbal IQ (β = 0.502, p = 0.001, adj.R² = 0.409), but not with performal IQ (β = 0.241, p > 0.05, adj.R² = 0.259). No difference in Total ToM SDS was found between children with deletion and maternal uniparental disomy (β = ?0.143, p > 0.05, adj.R² = ?0.016). Compared to the reference group of healthy children aged 7–12 years, children with PWS in the same age group had a median ToM developmental delay of 4 (3–5) years. One third of children with PWS scored positive for Autism Spectrum Disorder. Most prominent aberrations in Autism Spectrum Disorder were focused on maladaptive behavior. Our findings demonstrate a markedly reduced level of social cognitive functioning, which has consequences for the approach of children with PWS, i.e. adjustment to the child's level of social cognitive functioning.

Students’ and teachers’ perceptions of aggressive behaviour in adolescents with intellectual disability and typically developing adolescents

This study investigated aggressive behaviour in Serbian adolescents with intellectual disability (ID) compared to typically developing peers. The sample consisted of both male and female adolescents aged 12–18 years. One hundred of the adolescents had ID, and 348 adolescents did not have ID. The adolescents were asked to complete the Reactive-Proactive Aggression Questionnaire (RPQ), and their teachers provided ratings of aggression for the adolescents using the Children's Scale of Hostility and Aggression: Reactive-Proactive (C-SHARP). Results indicated that adolescents reported a higher prevalence of aggressive behaviour than their teachers. Reactive aggression was more prevalent than proactive aggression in both subsamples. In the subsample of adolescents with ID, there were no sex or age differences for aggression. However, in the normative subsample, boys and older adolescents scored significantly higher on aggression. According to adolescent self-reports the prevalence of aggression was higher in adolescents without ID, while teachers perceived aggressive behaviour to be more prevalent in adolescents with ID. Scientific and practical implications are discussed.     

Do Children with Autism Spectrum Disorder Share Fairly and Reciprocally?

This study investigated whether children with autism spectrum disorder (ASD) and typically developing children matched on receptive language share resources fairly and reciprocally. Children completed age-appropriate versions of the Ultimatum and Dictator Games with real stickers and an interactive partner. Both groups offered similar numbers of stickers (preferring equality over self-interest), offered more stickers in the Ultimatum Game, and verbally referenced ‘fairness’ at similar rates. However, children with ASD were significantly more likely to accept unfair offers and were significantly less likely to reciprocate the puppet’s offers. Failure to reciprocate fair sharing may significantly impact on social cohesion and children’s ability to build relationships. These important differences may be linked to broader deficits in social-cognitive development and potentially self-other understanding.     

Practitioner’s Guide to Assessment of Autism Spectrum Disorders in Infants and Toddlers

Recent advances in clinical research have made it possible to diagnosis autism spectrum disorders (ASD) as early as the second year of life. The diagnostic process early in development is often complex, and thus, familiarity with the most recent findings in clinical assessment instruments, early symptoms, and developmental trajectories of young children with autism is essential. This paper provides an empirically based practitioner's guide to issues and concerns related to early diagnosis of ASD in very young children, documentation of the course and patterns of ASD symptomatology in infants and toddlers, and current understanding in the field of diagnostic outcomes of children identified in the first and second year of life.     

Modification of the Children’s Sleep Habits Questionnaire for Children with Autism Spectrum Disorder

Sleep problems are common in children with autism spectrum disorder (ASD) and adversely impact daytime functioning. Although no questionnaires have been developed to assess sleep in children with ASD, the 33-item Children’s Sleep Habits Questionnaire (CSHQ) is widely used in this population. We examined the factor structure of the CSHQ in 2872 children (age 4–10 years) enrolled in the Autism Treatment Network. A four-factor solution (Sleep Initiation and Duration, Sleep Anxiety/Co-Sleeping, Night Waking/Parasomnias, and Daytime Alertness) with 5–6 items per factor explained 75% of the total variation. Ten items failed to load on any factor. This abbreviated 23-item four-factor version of this measure may be useful when assessing sleep in children with ASD.     

Documenting and Understanding Parent’s Intervention Choices for Their Child with Autism Spectrum Disorder

Understanding why parents choose some interventions but not others for their child with autism is important for a number of reasons. Estimating the proportion of evidence-based interventions engaged, identifying the agencies influencing parental decisions, and elucidating the barriers or reasons leading to intervention rejection or discontinuation can result in better service provision. New Zealand parents (n?=?570) of a child with autism reported what interventions were being engaged, and why some interventions were engaged but not others. Funding was a major determinant of intervention engagement, while medical professionals exerted the most influence. Sources of support were not related to intervention engagement, but parental perceptions of their child’s symptom severity were. Finally, non-engagement does not necessarily reflect parental opposition to an intervention, but rather the existence of barriers.     

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.
