ItemLanguage and social-emotional and behavioural wellbeing from 4 to 7 years: a community-based study(SPRINGER, 2018-07)Language disorder (LD) and social-emotional and behavioural (SEB) difficulties are common childhood problems that often co-occur. While there is clear evidence of these associations from clinical samples, less is known about community samples. This paper examines these associations in children aged 4-7 years from a community-based longitudinal study. 771 families provided questionnaire and assessment data at 4, 5 and 7 years. Parent-reported SEB difficulties were measured at each point (SDQ). Child language was directly assessed at 4 (CELF-P2), 5 and 7 years (CELF-4). Linear regression analysis was used to compare cross-sectional differences in mean SDQ scores between children with and without LD at each time point. Linear regression was then used to examine how patterns of language development (language disordered at three time points; never disordered; disordered at one or two time points, i.e. 'unstable' group) related to SEB difficulties at each age, adjusted for potential confounders, as in the previous analyses. Higher hyperactivity/inattention scores were associated with LD at each age. In fully adjusted models, there was little difference in mean emotional symptoms scores between children with and without LD. The 'never' LD group had lower mean SDQ scores at each time point than the 'unstable' group. Findings highlight that children with persistent LD from preschool to early primary school may be more likely to have concomitant SEB difficulties, particularly behavioural difficulties. Those with unstable LD may also have co-occurring SEB difficulties, showing a need for education and health professionals to monitor early language and SEB development.

ItemIntellectual development in autism spectrum disorders: new insights from longitudinal studies(FRONTIERS RESEARCH FOUNDATION, 2013-07-05)The presence/absence of Intellectual Disability (ID) is considered to be the most critical factor affecting outcomes in individuals with Autism Spectrum Disorders (ASD). However, the question of the specific nature of ID in ASD has received little attention, with the current view being that ID is a comorbid condition (i.e., one that is unrelated in etiology and causality from the ASD itself). Recent advances in developmental neuroscience, highlighting the importance of early exposure to social experiences for cognitive development, support an alternative view; that ID in ASD might emerge as a consequence of severe social-communication deficits on the experience-dependent mechanisms underlying neurocognitive development. We tested this prediction in two independent samples of young children with ASD (Ns = 23 and 60), finding that children with greater ASD severity at an initial assessment were more likely to present with poorer cognitive outcomes at a later assessment, irrespective of initial cognitive level. The results of this proof of principle study suggest that ASD symptom severity contributes to the extent to which the environmental input required to support "typical" brain development can be processed by the individual, so that the risk of developing ID increases as the number and severity of ASD social-communicative impairments increase.

ItemPredictors of outcomes in autism early intervention: why don't we know more?(FRONTIERS MEDIA SA, 2014)Response to early intervention programs in autism is variable. However, the factors associated with positive versus poor treatment outcomes remain unknown. Hence the issue of which intervention/s should be chosen for an individual child remains a common dilemma. We argue that lack of knowledge on "what works for whom and why" in autism reflects a number of issues in current approaches to outcomes research, and we provide recommendations to address these limitations. These include: a theory-driven selection of putative predictors; the inclusion of proximal measures that are directly relevant to the learning mechanisms demanded by the specific educational strategies; the consideration of family characteristics. Moreover, all data on associations between predictor and outcome variables should be reported in treatment studies.

Item"Are you available for the next 18 months?"-methods and aims of a longitudinal birth cohort study investigating a universal developmental surveillance program: the 'Watch Me Grow' study(BMC, 2014-09-22)BACKGROUND: Universal developmental surveillance programs aimed at early identification and targeted early intervention significantly improve short- and long-term outcomes in children at risk of developmental disorders. However, a significant challenge remains in providing sufficiently rigorous research and robust evidence to inform policy and service delivery. This paper describes the methods of the 'Watch Me Grow' study that aims to maximise accurate early detection of children with developmental disorders through a partnership formed between policy makers, service providers and researchers. METHODS/DESIGN: A mixed methods study design was developed consisting of: (1) a qualitative study of parents and health service providers to investigate barriers and enablers of developmental surveillance; (2) recruitment of a birth cohort and their longitudinal follow-up to 18 months of age to: a) assess risk factors for not accessing existing developmental surveillance programs and b) estimate the prevalence of children identified with developmental risk; (3) comparison of surveillance outcomes with a reference standard at 18 months of age to assess the diagnostic test accuracy of existing and alternative developmental surveillance tools; and (4) comparison of developmental surveillance models to inform policy recommendations. Data linkage will be used to determine the uptake and representativeness of the study participant group versus non-participants. DISCUSSION: The Watch Me Grow study is expected to provide a collaborative opportunity to enhance universal developmental surveillance for early accurate identification of developmental risk. This will also provide quality evidence about identification of developmental risk and access to services to be embedded in existing practice with linkages to policy development.

ItemFirst evidence of sensory atypicality in mothers of children with Autism Spectrum Disorder (ASD)(BMC, 2014-04-03)BACKGROUND: Atypical reactions to sensory stimuli show heritability in the general population and are a known risk factor for affective disorders. As sensory problems are highly prevalent in individuals with ASD and their siblings, and the occurrence of affective disorders is elevated in parents of children with ASD, investigating sensory symptoms in parents is important both from clinical and theoretical standpoints.Fifty mothers of children and adolescents with ASD completed the Adolescent and Adult Sensory Profile (AASP). The AASP is a norm-referenced questionnaire that provides scores for four types of responses to sensory stimuli (sensory quadrants): hypo-sensitivity, hyper-sensitivity, sensation seeking, and sensory avoiding. FINDINGS: Mothers' scores were compared with AASP norms. Ninety eight percent of mothers had sensory scores at least one standard deviation (SD) above the normative mean and 44% were two or more SDs above the mean for at least one sensory quadrant. CONCLUSIONS: This study provides the first evidence for sensory atypicality in parents of children with ASD. Further research is needed to elucidate the contribution of genetic and environmental influences on the expression of sensory problems in ASD.

Item"Tuning into Kids": Reducing Young Children's Behavior Problems Using an Emotion Coaching Parenting Program(SPRINGER, 2013-04)This study evaluated a 6-session group parenting program, Tuning into Kids (TIK), as treatment for young children (aged 4.0-5.11 years) with behavior problems. TIK targets parent emotion socialization (parent emotion awareness, regulation and emotion coaching skills). Fifty-four parents, recruited via a child behavior clinic, were randomized into intervention (TIK) or waitlist (clinical treatment as usual). Parents reported emotion awareness/regulation, emotion coaching, empathy and child behavior (pre-intervention, post-intervention, 6-month follow-up); teachers reported child behavior and observers rated parent-child emotion coaching and child emotion knowledge (pre-intervention, follow-up). Data were analyzed using growth curve modeling and ANCOVA. Parents in both conditions reported less emotional dismissiveness and reduced child behavior problems; in the intervention group, parents also reported greater empathy and had improved observed emotion coaching skills; their children had greater emotion knowledge and reduced teacher-reported behavior problems. TIK appears to be a promising addition to treatment for child behavior problems.

ItemConsequences of childhood reading difficulties and behaviour problems for educational achievement and employment in early adulthood(WILEY, 2017-06)BACKGROUND: Reading difficulties (RDs) and behaviour problems (BPs) are two common childhood problems that have a high degree of stability and often negatively affect well-being in both the short and longer terms. AIMS: The study aimed to shed light on the unique and joint consequences of these two childhood problems for educational and occupational outcomes in early adulthood. SAMPLE: Data were drawn from a life-course longitudinal study of psychosocial development, the Australian Temperament Project. METHODS: Parent and teacher reports and a standard reading test were used to define four groups of children at 7-8 years: RDs only; BPs only; both problems; and neither problem. These groups were followed forward to ascertain educational attainment and employment status at 19-20 and 23-24 years. RESULTS: Each childhood problem was a unique risk for poorer educational and occupational outcomes, with co-occurring problems significantly increasing the risk of poorer educational outcomes. Further analyses revealed that the effects of childhood BPs on occupational status were mediated by secondary school non-completion, but childhood RDs were not. CONCLUSIONS: The findings point to the importance of screening and early intervention to prevent or minimize the development of these two childhood problems, as well as continuing to support vulnerable children to increase their likelihood of secondary school completion.

ItemNo evidence for the Mozart effect in children(University of California Press, 2006)The Mozart effect refers to claims that listening to Mozart-like music results in a small, short-lived improvement in spatiotemporal performance. Based on predominantly adult research that has shown equivocal findings, there has been speculation that the Mozart effect may have pedagogical benefits for children. The present study aimed to examine the Mozart effect in children and to evaluate two alternative models proposed to account for the effect, namely the trion model and the arousal-mood model. One hundred and thirty-six Grade 5 students (mean age 10.7 years) were exposed to three experimental listening conditions: Mozart piano sonata K. 448, popular music, and silence. Each condition was followed by a spatiotemporal task, and mood and music questionnaires. The results showed no evidence of a Mozart effect. Speculation about applications of the Mozart effect in children needs to be suspended until an effect can be reliably reproduced.
