This network has established a cohort of self- and proxy-reported individuals and their family members with ASD in New Zealand. The aim of this manuscript is to present the New Zealand Minds for Minds Autism Spectrum Disorder Self-Reported Cohort, M4M cohort for short, and to provide preliminary insights into the trends of ASD in New Zealand through the analysis of diagnostic and sociodemographic information of 972 members (ages 2–83) of this cohort, the majority of which were carer-reported. Method The participants were recruited via an internet-based questionnaire, and social network analysis was used to visually analyse the mutual interactions of the cohort. Results We observed the well-reported gender bias and an ethnic structure that reflects New Zealand’s most recent census. Comorbidity patterns were consistent with epidemiological literature: anxiety disorders, depression and epilepsy were highly prevalent amongst individuals with ASD and their families. This is the first national large-scale ASD research cohort, which contains an ethnic composition unique to the country. It is anticipated that the multi-disciplinary research approach of this cohort will help inform health policies in New Zealand and contribute to the international effort to better understand ASD.

Self-efficacy and burnout in teachers of students with autism spectrum disorder / Emilie BOUJUT in Research in Autism Spectrum Disorders, 36 (April 2017)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 36 (April 2017) . - p.8-20 Titre : Self-efficacy and burnout in teachers of students with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Emilie BOUJUT, Auteur ; Maria POPA-ROCH, Auteur ; Emilie-Anne PALOMARES, Auteur ; Annika DEAN, Auteur ; Emilie CAPPE, Auteur Article en page(s) : p.8-20 Langues : Anglais (eng) Mots-clés : Self-efficacy  Burnout  Autism spectrum disorder  School inclusion  Mediation  Teachers Index. décimale : PER Périodiques Résumé : Inclusion in schools of students with autism spectrum disorder (ASD) is a source of stress for teachers and requires a certain amount of adaptation to deal with it. The effects of perceived self-efficacy on burnout in professionals have been substantiated but the indirect effects, mediated by transactional processes of stress and coping, have never been explored in this specific context. This study aims to test the mediating effect of perceived stress and coping strategies on the relationship between perceived self-efficacy and burnout. Method A sample of 203 teachers of students with ASD filled out four self-report questionnaires measuring perceived self-efficacy, perceived stress, coping strategies, and burnout. A multiple mediation analysis was carried out using the bootstrap procedure. Results After controlling for the direct effect of perceived self-efficacy on burnout, the indirect effects through transactional processes were significant. The lower the teachers’ feeling of self-efficacy, the more they implemented emotion-focused coping strategies, which predict higher burnout in all three of its dimensions. Moreover, the lower the teachers’ feeling of self-efficacy, the more they perceived the stressful situation in question as a threat or loss, perceptions that generate more emotional exhaustion. These results enable us to formulate some ideas for improving both the wellbeing of teachers working with students with ASD and the management of such students, and thus their learning abilities and wellbeing in school.

YODER, Auteur Article en page(s) : p.21-34 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Communication  Early childhood  Early intervention  Intentional communication  Pragmatic function Index. décimale : PER Périodiques Résumé : Theoretically, specific pragmatic functions of intentional communication are differentially associated with language use in children with autism spectrum disorder (ASD). The primary purpose of this meta-analysis was to compare the relation of declarative and imperative intentional communication acts (ICAs), respectively, with language skills. We also examined five possible moderators of the separate associations and the difference in associations: metric used to quantify ICAs, expressive versus receptive language, longitudinal or concurrent correlations, within-study interobserver reliability of rating pragmatic function of ICAs, and risk for correlated measurement error. Method Included studies provided at least 1 zero-order correlation (concurrent or longitudinal) of language measures with declarative or imperative ICAs. Participants were children with ASD (n = 727), aged 8 years and younger. Results Twenty-three studies were included. Declarative ICAs were significantly associated with language (weighted mean r = 0.42; 95% CI [0.34, 0.50]). Imperative ICAs were not significantly associated with language. Moderator effects were not detected. Conclusions The association of declarative ICAs and language has implications for early treatment of ASD-related language deficits. Failure to find a significant association of imperative ICAs and language could have been due to low statistical power and/or publication bias; more research on imperative ICAs is needed.

VAN DER VEGT, Auteur Article en page(s) : p.35-43 Langues : Anglais (eng) Mots-clés : ASD  Psychosexual development  Adolescence  Inappropriate sexual behaviour Index. décimale : PER Périodiques Résumé : Inappropriate sexual behaviour, sexual problems and sexual victimization in adolescents with autism spectrum disorders (ASD) is regularly reported in previous research, but little is known about factors associated with these problems, nor about factors associated with a healthy sexuality development in adolescents with ASD. Investigating the judgement of sexual behaviour can be a first step in acquiring insight into inappropriate sexual behaviour in adolescents with ASD. Methods We assessed how 94 cognitively-able adolescents with ASD and 94 typically developing (TD) adolescents judged the appropriateness of different illustrations of sexual situations and we investigated the differences between the two groups. Results The highest level of agreement between the judgements of adolescents with ASD and the judgements of an expert panel was found for severely inappropriate sexual behaviours (89.2%) and the lowest agreement was found for appropriate (31.7%) and slightly inappropriate sexual behaviours (26.1%). No significant differences were found between the judgements of the adolescents with ASD and the TD adolescents. Regarding the divergent judgements, adolescents with and without ASD were mostly more strict (i.e., more conservative) than the expert panel in their judgement of sexual situations. Finally, a small percentage of adolescents with and without ASD showed milder (i.e., less conservative) judgements of sexual situations portraying behaviour that was considered severely inappropriate by an expert panel. Conclusions Our findings showed that, overall, judgement of illustrations of sexual situations does not seem to be hampered in adolescents with ASD. More research is needed to clarify whether this also holds true for their judgements of – and actions in – more complex real life situations.

A systematic review of sensory-based autism subtypes / Kelle K. DEBOTH in Research in Autism Spectrum Disorders, 36 (April 2017)

Sensory-based subtypes have been proposed as a means to better understand the unique sensory qualities in this clinical population. The purpose of this systematic review is to synthesize information about sensory-based subtypes that have been reported in the literature for children with autism. Methods PRISMA guidelines informed this review process. Included articles were published in the last 12 years, specific to children with autism between the ages of 2–18 years old. Of the 33 articles meeting eligibility for full-text review, 8 matched the final inclusion criteria. Results Findings indicate that sensory-based subtypes in children with autism were developed using primarily parent-report instruments that assess differences in sensory responsivity. Several different subtyping schemes were presented, suggesting between three to five subtypes as an appropriate fit to encompass the different patterns of sensory responsivity seen in children with autism. Several studies suggest that a subgroup of this population has typical sensory functioning, and a subgroup exists with significant, global sensory differences. Mixed results were found for those children who fall in between, who have specific versus global differences in responsivity (i.e., hyper- or hyporesponsivity or sensory seeking), or within specific sensory domains. The literature consists of a small number of descriptive studies with little consensus on subtypes. Initial findings indicate that service providers may be able to consider variable presentations of sensory processing differences in their approach to treatment and intervention planning, but further research is indicated.

We hypothesized that adolescents with ASD would show reduced ANS response to social threat. Methods Eighteen males with ASD and thirteen males with typical development (TD), ages 12 to 17, completed a social threat paradigm while wearing an impedance cardiography apparatus. We calculated pre-ejection period (PEP) and tested for between-group differences in PEP response to social threat. We also conducted correlation analyses between PEP change scores and clinical symptom scales. Results There was an effect of diagnosis on change in PEP from baseline to the onset of social threat (F = 7.60, p = 0.01), with greater changes in PEP in TD compared to ASD. PEP change score and the Social Communication Questionnaire (r = 0.634, p = 0.005) and the ADHD Problems Subscale of the Child Behavior Checklist (r = 0.568, p = 0.014) were correlated. These findings suggest reduced arousal in response to social threat in ASD, with preliminary evidence that reduced sympathetic activation is associated with increased social behavior symptoms.

A cluster analysis exploration of autism spectrum disorder subgroups in children without intellectual disability / Felicity KLOPPER in Research in Autism Spectrum Disorders, 36 (April 2017)

The presence of phenotypic subgroups continues to be questioned. This study investigated whether children with ASD without ID are differentiable into clinically meaningful subgroups. Method Data from the ‘gold standard’ ASD diagnostic instruments for 61 children (5–14 years) with ASD without ID were subjected to exploratory cluster analysis. Cognition, language, pragmatic communication, and behaviour were used to explore subgroups. Results Children with ASD without ID could be differentiated into Moderate and Severe Social Impairment subgroups when core ASD symptoms were more closely examined. The Moderate Social Impairment subgroup showed less severe social interaction and communication impairments but greater lifetime severity of restricted/repetitive behaviours. In contrast, the Severe Social Impairment subgroup, with poorer social interaction and communication skills, had lower lifetime severity of restricted/repetitive behaviours. This subgroup also had greater cognitive and language difficulties, and poorer adaptive functioning. Importantly, however, these neurocognitive and functional differences showed only small to moderate associations with the differentiated ASD clinical profiles. Conclusions Evidence of dissociated levels of severity across core ASD dimensions supports the idea that clinically meaningful subgroups within ASD without ID can be identified. The dissociated profiles of ASD features could represent different underlying neurobiological mechanisms for each subgroup. Identifying such subgroups in practice can improve the clinical utility of diagnostic labels in this population. Thus, both categorical and dimensional approaches may be useful in classifying ASD, with neither alone being adequate.

Interventions for toddlers with autism spectrum disorder: A meta-analysis of single-subject experimental studies / Ellen DEBODINANCE in Research in Autism Spectrum Disorders, 36 (April 2017)

Concurrently, intervention research for toddlers with ASD has increased since the past decade. Method In this study, we report on a five-level meta-analysis of 34 single-subject experimental studies, intended to offer a better insight into what types of interventions are effective for toddlers under the age of three with or at risk for ASD. Results The analysis revealed a significant positive overall effect size. We found that interventions at home were significantly more effective compared to those in other settings.

Concurrently, intervention research for toddlers with ASD has increased since the past decade. Method In this study, we report on a five-level meta-analysis of 34 single-subject experimental studies, intended to offer a better insight into what types of interventions are effective for toddlers under the age of three with or at risk for ASD. Results The analysis revealed a significant positive overall effect size. We found that interventions at home were significantly more effective compared to those in other settings. Other significant moderators regarding intervention characteristics were the agent of intervention and duration in weeks. No moderator effects of study and child characteristics were found. On average, interventions for toddlers with or at risk for ASD are successful.
