Temperament in the First 2 Years of Life in Infants at High-Risk for Autism Spectrum Disorders / Sally M. CLIFFORD in Journal of Autism and Developmental Disorders, 43-3 (March 2013)
[article]
Titre : Temperament in the First 2 Years of Life in Infants at High-Risk for Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Sally M. CLIFFORD, Auteur ; Kristelle HUDRY, Auteur ; Mayada ELSABBAGH, Auteur ; Tony CHARMAN, Auteur ; Mark H. JOHNSON, Auteur Article en page(s) : p.673-686 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Broader autism phenotype High-risk siblings Temperament Index. décimale : PER Périodiques Résumé : The current study investigated early temperament in 54 infants at familial high-risk of ASD and 50 controls. Parental report of temperament was assessed around 7, 14 and 24 months of age and diagnostic assessment was conducted at 3 years. The high-risk group showed reduced Surgency at 7 and 14 months and reduced Effortful Control at 14 and 24 months, compared to controls. High-risk infants later diagnosed with ASD were distinguished from controls by a temperament profile marked by increased Perceptual Sensitivity from the first year of life, and increased Negative Affect and reduced Cuddliness in the second year of life. Temperament may be an important construct for understanding the early infant development of ASD.

Titre : The Modified-Classroom Observation Schedule to Measure Intentional Communication (M-COSMIC): Evaluation of reliability and validity Type de document : Texte imprimé et/ou numérique Auteurs : Sally M. CLIFFORD, Auteur ; Tony CHARMAN, Auteur ; Greg PASCO, Auteur ; Kristelle HUDRY, Auteur ; Laura BROWN, Auteur ; PACT CONSORTIUM, Auteur Année de publication : 2010 Article en page(s) : p.509-525 Langues : Anglais (eng) Mots-clés : Autism-spectrum-disorders Observation Ecological-validity Social-Communication School Measurement Index. décimale : PER Périodiques Résumé : The Modified-Classroom Observation Schedule to Measure Intentional Communication (M-COSMIC) was developed as an ecologically valid measure of social-communication behaviour, delineating forms, functions, and intended partners of children's spontaneous communication acts. Forty-one children with autism spectrum disorder (ASD) aged 48–73 months were filmed within small-group settings at school. Communication behaviours during a 5-min teacher-led activity and a 10-min free-play session were coded from videotape. Inter-rater reliability was high. Many M-COSMIC codes were significantly associated as predicted with Social and Communication domain scores on the Autism Diagnostic Observation Schedule (ADOS) and with scores on standardised language assessments. Agreement was more variable, however, at the level of individual M-COSMIC codes and ADOS items. Higher rates of responding, compliance behaviours and following pointing gestures and gaze occurred during the more structured teacher-led activity, compared to the free-play. Results demonstrate preliminary construct validity of the M-COSMIC, showing its potential to describe and evaluate spontaneous social-communication skills in young children with ASD for research and applied purposes.

[article]
Titre : The Role of Negative Affectivity in Concurrent Relations Between Caregiver Psychological Distress and Social-Emotional Difficulties in Infants With Early Signs of Autism Type de document : Texte imprimé et/ou numérique Auteurs : Lacey CHETCUTI, Auteur ; Mirko ULJAREVIC, Auteur ; Kandice J. VARCIN, Auteur ; Maryam BOUTRUS, Auteur ; Ming Wai WAN, Auteur ; Vicky SLONIMS, Auteur ; Jonathan GREEN, Auteur ; Leonie SEGAL, Auteur ; Teresa IACONO, Auteur ; Cheryl DISSANAYAKE, Auteur ; Andrew J. O. WHITEHOUSE, Auteur ; Kristelle HUDRY, Auteur Article en page(s) : p.1349-1357 Langues : Anglais (eng) Mots-clés : autism spectrum disorder caregivers infant social-emotional difficulties temperament Index. décimale : PER Périodiques Résumé : Recent evidence suggests the link between caregiver psychological distress and offspring social-emotional difficulties may be accounted for by offspring temperament characteristics. However, existing studies have only focused on neurotypical children; thus, the current study sought to provide an initial examination of this process among children with varying levels of early autism features. Participants included 103 infants aged 9-16?months (M = 12.39, SD = 1.97; 68% male) and their primary caregiver (96% mothers) referred to a larger study by community healthcare professionals. We utilized caregiver-reported measures of psychological distress (Depression Anxiety Stress Scales), infant temperament (Infant Behavior Questionnaire-Revised) and internalizing and externalizing symptoms (Infant-Toddler Social and Emotional Assessment) and administered the Autism Observation Schedule for Infants (AOSI) at an assessment visit to quantify autism features. Infant negative affectivity was found to mediate positive concurrent relations between caregiver psychological distress and infant internalizing and externalizing symptoms, irrespective of the infants' AOSI score. While preliminary and cross-sectional, these results replicate and extend previous findings suggesting that the pathway from caregiver psychological distress to negative affectivity to social-emotional difficulties might also be apparent among infants with varying levels of autism features. More rigorous tests of causal effects await future longitudinal investigation. LAY SUMMARY: Offspring of caregivers experiencing psychological distress (i.e., symptoms of depression, anxiety, and/or stress) may themselves be at increased risk of poor mental health outcomes. Several previous studies conducted with neurotypical children suggest that this link from caregiver-to-child may be facilitated by children's temperament qualities. This study was a preliminary cross-sectional exploration of these relationships in infants with features of autism. We found that infants' elevated negative emotions were involved in the relation between caregiver heightened psychological distress and children's mental health difficulties, consistent with neurotypical development.

Titre : Treatment mechanism in the MRC preschool autism communication trial: implications for study design and parent-focussed therapy for children Type de document : Texte imprimé et/ou numérique Auteurs : Andrew PICKLES, Auteur ; Victoria HARRIS, Auteur ; Jonathan GREEN, Auteur ; Catherine ALDRED, Auteur ; Helen MCCONACHIE, Auteur ; Vicky SLONIMS, Auteur ; Ann LE COUTEUR, Auteur ; Kristelle HUDRY, Auteur ; Tony CHARMAN, Auteur ; THE PACT CONSORTIUM,, Auteur Article en page(s) : p.162-170 Langues : Anglais (eng) Mots-clés : Autism measurement error mediation parent–child interaction parent-focussed therapy Index. décimale : PER Périodiques Résumé : Background The PACT randomised-controlled trial evaluated a parent-mediated communication-focused treatment for children with autism, intended to reduce symptom severity as measured by a modified Autism Diagnostic Observation Schedule-Generic (ADOS-G) algorithm score. The therapy targeted parental behaviour, with no direct interaction between therapist and child. While nonsignificant group differences were found on ADOS-G score, significant group differences were found for both parent and child intermediate outcomes. This study aimed to better understand the mechanism by which the PACT treatment influenced changes in child behaviour though the targeted parent behaviour. Methods Mediation analysis was used to assess the direct and indirect effects of treatment via parent behaviour on child behaviour and via child behaviour on ADOS-G score. Alternative mediation was explored to study whether the treatment effect acted as hypothesised or via another plausible pathway. Mediation models typically assume no unobserved confounding between mediator and outcome and no measurement error in the mediator. We show how to better exploit the information often available within a trial to begin to address these issues, examining scope for instrumental variable and measurement error models. Results Estimates of mediation changed substantially when account was taken of the confounder effects of the baseline value of the mediator and of measurement error. Our best estimates that accounted for both suggested that the treatment effect on the ADOS-G score was very substantially mediated by parent synchrony and child initiations. Conclusions The results highlighted the value of repeated measurement of mediators during trials. The theoretical model underlying the PACT treatment was supported. However, the substantial fall-off in treatment effect highlighted both the need for additional data and for additional target behaviours for therapy.

GREEN, Auteur ; Patricia LEE, Auteur ; Emily MA, Auteur ; Helen SAID, Auteur ; Rena WANG, Auteur ; Sarah WOOD, Auteur ; Kristelle HUDRY, Auteur Article en page(s) : p.102227 Mots-clés : Autism Participatory research Migrants Parent experiences Early intervention Index. décimale : PER Périodiques Résumé : Background Parents should be central to early supports for their autistic children, with parent involvement in and satisfaction with supports influencing child outcomes. Migrant parents likely experience different barriers to navigating and participating in early supports for their autistic children, but we have limited data here. Methods Through a community-partnered participatory approach, we conducted semi-structured interviews with 19 migrant Chinese parents of autistic children about their experiences of the diagnosis and early intervention (EI) process. Interviews were conducted in home languages by other parents. We analysed data using reflexive thematic analysis. Results Parents described myriad obstacles to accessing early supports with many related to being a Chinese migrant in Australia. Parents reported difficulties accepting their children?s differences, faced language barriers, experienced stigmatisation/discrimination, and had limited knowledge of autism supports/systems. Funding issues, limited availability of supports and poorly coordinated services were additional challenges. Parents described having little choice and control over supports, often unable to access culturally-specific services. Nonetheless, parents explained how dedicated they were to their children and effectively utilised informal networks to better access supports for themselves and their children. Accessing EI gave parents hope, providing them with specific goals and strategies. Conclusion It is recommended that professionals clearly communicate with migrant parents about autism and available post-diagnostic autism services/supports, including how to access these. Connecting parents with informal, community-specific services should especially be considered for migrant families. We recommend other potentially useful adaptations to better support migrant Chinese parents in navigating early supports for their autistic children.
