Smith, Jodie, Levickis, Penny, Eadie, Tricia, Bretherton, Lesley, Conway, Laura, and Goldfeld, Sharon
- Abstract
Background: Variations in parenting, more specifically less responsive and more directive parenting, contribute to language difficulties for children experiencing adversity. Further investigation of associations between specific responsive and directive behaviours and child language is required to understand how behaviours shape language over time within different populations. As language is dyadic, further exploration of how mother-child interactions moderate associations is also important. Aims: To investigate associations between specific responsive and directive maternal behaviours, the quality of mother-child interaction (fluency and connectedness) and child language in a cohort experiencing adversity. Methods & Procedures: Pregnant women experiencing adversity were recruited from maternity hospitals in Australia. At 12 months, videos of mother-infant free play were collected. Videos were coded for maternal behaviours and fluency and connectedness (n = 249). At 36 months, child language was measured using a standardized language test. Linear regression models were used to examine associations and the moderating role of fluency and connectedness was explored. Outcomes & Results: Responsive yes/no questions were positively associated with language scores. Unsuccessful redirectives were negatively associated with language scores. The moderation effect of fluency and connectedness was equivocal in the current data. Conclusions & Implications: Findings reproduce and extend previous research highlighting key features of mother-child interactions associated with child language trajectories. Findings also augment knowledge of risk and protective factors related to language for children experiencing adversity and highlight where targeted interventions might be successful.

- Abstract
Background: Parent-reported measures of early communication have limitations for use with infants experiencing adversity. Observational measures of early non-verbal and verbal communicative behaviours and mother-child turn-taking may provide a complementary method of capturing early communication skills for these children. Aims: To explore the predictive validity of verbal and non-verbal behaviours and mother-child conversational turn-taking (fluency and connectedness) at child age 12 months in relation to language measures at 24 and 36 months in a cohort of infants experiencing adversity. Methods & Procedures: Pregnant women experiencing adversity were recruited from maternity hospitals in Australia. At 12 months, 190 infants were videoed during mother-child free-play. Verbal and non-verbal communicative behaviours and fluency and connectedness were measured from the 12-month videos. Predictive validity of 12-month behaviours was calculated in relation to mean length of utterance and number of unique words at 24 months and Clinical Evaluation of Language Fundamentals Preschool--Second Edition (CELF-P2) Core Language scores at 36 months. Outcomes & Results: All 12-month behaviours had adequate specificity but poor sensitivity when compared with other predictive validity studies using published early language measures. However, in adjusted regression models, fluency and connectedness and verbal behaviours at 12 months predicted unique words at 24 months. Fluency and connectedness also predicted CELF-P2 scores at 36 months. Conclusions & Implications: Findings reconfirm the difficulty in early identification of children at risk of later language difficulties. All 12-month measures were more accurate at identifying those children who will have better language than those children who will not. As fluency and connectedness was the only measure to predict 24- and 36-month language in adjusted regression models, it may be an important factor to consider when measuring early language skills for infants experiencing adversity. Future research could combine observational measures of early communication and fluency and connectedness with other predictors of language to try to increase prediction accuracy.

Serry, Tanya A., Liamputtong, Pranee, Rose, Miranda L., and Bretherton, Lesley
- Abstract
We examined the lived experiences of twelve parents of low-progress readers. Parents were recruited from five state schools in Melbourne and each participated in individual interviews. Analyses revealed that most children received Reading Recovery which was the first and often only option. Parents were divided regarding satisfaction with their children's reading outcomes following this program. Sources of dissatisfaction included: a waiting list for commencement of intervention, the sudden cessation of Reading Recovery based on the 100-session limit, and Reading Recovery's theoretical orientation towards constructivist principles. Half the parents independently sought external reading intervention from conventional and non-conventional service providers. Moreover, many parents encountered a personal toll related to their children's reading difficulty. This study highlights the needs of parents who are important stakeholders in the management of low-progress readers. Our findings call for a more systematic, integrated and mindful approach between educators, policy makers and parents of low-progress readers.

12. Developing a Comprehensive Model of Risk and Protective Factors That Can Predict Spelling at Age Seven: Findings from a Community Sample of Victorian Children
- Author

Serry, Tanya Anne, Castles, Anne, Mensah, Fiona K., Bavin, Edith L., Eadie, Patricia, Pezic, Angela, Prior, Margot, Bretherton, Lesley, and Reilly, Sheena
- Abstract
The paper reports on a study designed to develop a risk model that can best predict single-word spelling in seven-year-old children when they were aged 4 and 5. Test measures, personal characteristics and environmental influences were all considered as variables from a community sample of 971 children. Strong concurrent correlations were found between single-word spelling and single-word reading while expressive language and, to a lesser extent, receptive language were less strongly correlated. Predictors of single-word spelling at ages 4 and 5 were dominated by child-related factors such as letter knowledge, a history of speech impairment and expressive language along with maternal word reading ability. Based on the strength of the predictive factors identified at both age 4 and 5, our results provide initial support for using a targeted model for screening pre-schoolers at risk of not mastering spelling in a timely manner.

14. Stability of Language Performance at 4 and 5 Years: Measurement and Participant Variability
- Author

Eadie, Patricia, Nguyen, Cattram, Carlin, John, Bavin, Edith, Bretherton, Lesley, and Reilly, Sheena
- Abstract
Background: Language impairment (LI) in the preschool years is known to vary over time. Stability in the diagnosis of LI may be influenced by children's individual variability, the measurement error of commonly used assessment instruments and the cut-points used to define impairment. Aims: To investigate the agreement between two different age-based versions of a language assessment instrument and the stability of the classification of LI using the two measures over a 12-month period. Methods & Procedures: A total of 945 participants completed the Clinical Evaluation of Language Fundamentals (CELF-Preschool 2 or 4th Edn) at 4 and 5 years of age. Agreement and stability were analysed using Bland-Altman plots, correlation and odds ratios. Sensitivity and specificity were calculated for two thresholds of the CELF-P2 using the diagnostic category on the child's subsequent CELF-4. Outcomes & Results: For all CELF scores, mean differences for the cohort between 4 and 5 years were within 1.5 scale score units. In contrast, at the individual level variability was found across the range of scores and was of a greater magnitude than previously reported. Stability in LI classification was low, with 36% of 5-year-olds with LI (defined as a standard score below -1.25) classified as typical at 4 years, even though odds ratios calculated from classifications at the two time points suggested that 4-year-olds with LI had 23 times greater odds than their typical peers to receive a diagnosis of LI at 5 years. The CELF-P2 did not demonstrate adequate levels of diagnostic accuracy for LI at 5 years: sensitivity of 64% and specificity of 92.9%. Conclusions: Substantial variability across the entire range of possible CELF scores was observed in this community cohort between the ages of 4 and 5 years. The stability of LI classification was lower than that reported in previous research conducted primarily on smaller clinical cohorts. The current study's results suggest that the variability observed in developmental language pathways is the result of a combination of limitations in measurement instruments, individual children's abilities and the arbitrary nature of the boundaries defining LI.

15. Developing Relationships between Language and Behaviour in Preschool Children from the Early Language in Victoria Study: Implications for Intervention

Bretherton, Lesley, Prior, Margot, Bavin, Edith, Cini, Eileen, Eadie, Patricia, and Reilly, Sheena
- Abstract
Following a biopsychosocial model, the study investigated the role of child factors (gender, IQ), maternal factors (psychological distress, maternal education and vocabulary, maternal distress) and environmental factors (SES) in the relationship between language impairment and behaviour problems in preschool children. Participants were drawn from the Early Language in Victoria Study (ELVS) a prospective, longitudinal study examining the epidemiology and natural history of language impairment. The study reports on 1257 participants from the ELVS who completed questionnaires at 2 and 4 years and also completed face-to-face assessments at 4 years of age. Information was collected on child language, non-verbal cognition and social-emotional development; maternal vocabulary, maternal psychological distress and parent--child interaction; and SES. This study showed that language impairment is specifically associated with hyperactivity and peer problems but not anxiety and conduct problems at the preschool stage. Children with language impairment were at a higher risk for clinical levels of 'abnormal' behaviour which could lead to a psychiatric diagnosis than typically developing children. An examination of biopsychosocial variables associated with language and behaviour revealed that although language ability was a predictor of behaviour at both 2 years and 4 years of age, maternal distress was a stronger predictor of behaviour, with the association stronger for boys than for girls. Early intervention directed to children, especially boys, with language impairment deserves further attention, especially during the preschool period, in order to ameliorate the impact of language impairment on peer relationships and disruptive behaviour in later school years.

17. Children with Specific Language Impairment and Resolved Late Talkers: Working Memory Profiles at 5 Years
- Author

Petruccelli, Nadia, Bavin, Edith L., and Bretherton, Lesley
- Abstract
Purpose: The evidence of a deficit in working memory in specific language impairment (SLI) is of sufficient magnitude to suggest a primary role in developmental language disorder. However, little research has investigated memory in late talkers who recover from their early delay. Drawing on a longitudinal, community sample, this study compared the memory profiles of 3 groups of 5-year-olds: children with SLI who had been identified as late talkers, resolved late talkers (RLTs), and children with typical language development (TLD). Method: Participants were 25 children with SLI, 45 RLTs, and 32 children with TLD. Subtests from the Working Memory Test Battery for Children and the Children's Memory Scale plus recalling sentences and nonword repetition tasks were administered to test the components of Baddeley's working memory model. Results: The SLI group showed significantly poorer performance than the RLT and TLD groups on measures of the phonological loop and episodic buffer. The RLT and TLD groups scored similarly on all memory measures. Conclusions: The results support previous findings that sentence recall and nonword repetition are markers of SLI. Although residual effects of late-talking status may emerge over time, RLTs do not necessarily show memory deficits at 5 years of age despite delayed early vocabulary development.

- Abstract
Background: Parent report instruments are frequently used for the identification of both "at-risk" children and to support the diagnosis of communication delay. Whilst the evidence is strong for the accuracy of parent report of vocabulary between 2 and 3 years, there are fewer studies that have considered the ability of parents to report on early communication behaviours in 12-month-old infants. Aims: To investigate the validity of the underlying structure of the Communication and Symbolic Behaviour Scales-Developmental Profile (CSBS-DP) for each of the direct observation and parent reports of communication behaviour in infants at 12 months of age. Methods & Procedures: Participants were 1725 infants, already participating in a longitudinal study of language development, whose parents completed the Infant-Toddler Checklist from the CSBS-DP. Seven hundred and twenty-eight (728) of these infants also completed the Behaviour Sample from the CSBS-DP. The structure of the CSBS-DP was examined using confirmatory factor analyses (CFA) of the Behaviour Sample and the Infant-Toddler Checklist. Correlations between the Infant-Toddler Checklist and the Behaviour Sample on the total, composite, and subscale scores were also calculated. Outcomes & Results: Confirmatory factor analysis of the CSBS-DP Behaviour Sample replicated previous work conducted during the development of the instrument, but on a larger and younger cohort of Australian infants. The data provided support for at least three factors, broadly representing Social, Speech, and Symbolic communication skills, with some evidence that the speech factor could be further split into sub-factors representing Sounds and Words. There was support for a three-factor structure for the Infant-Toddler Checklist. Moderate correlations were found between results from the Behaviour Sample and the Infant-Toddler Checklist. Conclusions & Implications: As measures of early communication skill for young infants, the CSBS-DP Behaviour Sample and the Infant-Toddler Checklist are valid clinical tools for measuring constructs broadly representing Social, Speech, and Symbolic communication skills. The Speech composite in particular emerged as a strong factor under the Behaviour Sample. (Contains 1 figure, 8 tables, and 2 notes.)

- Abstract
Investigated the relationship between auditory temporal processing of nonspeech sounds and phonological awareness ability in 8- to 12-year-olds with a reading disability, placed in groups based on performance on Tallal's tone-order judgment task. Found that a tone-order deficit did not relate to performance on order processing of speech sounds, to poorer phonological awareness, or to more severe reading difficulties. (Author/KB)

Background: Public health advocates have highlighted internalising problems as a leading cause of global burden of disease. Internalising problems (anxiety/depression) affect up to 20% of school‐age children and can impact peer relations, school engagement and later employment and mortality. This translational trial aimed to determine whether a selective/indicated parenting group programme to prevent internalising distress in shy/inhibited preschool children had sustained effects in middle childhood. Translational design aspects were a brief parent‐report screening tool for child inhibition offered universally across the population via preschools in the year before school, followed by an invitation to parents of all inhibited children to attend the parenting programme at venues in their local community. Methods: Design of the study was a randomised controlled trial. The setting was 307 preschool services across eight socioeconomically diverse government areas in Melbourne, Australia. Participants were 545 parents of inhibited four‐year‐old children of which 456 (84%) were retained during middle childhood (age of seven to 10 years). Early intervention was the Cool Little Kids parenting group programme, and control was 'usual care' access to available support services in the community. Primary outcomes were child anxiety and depression symptoms (parent and child report) and DSM‐IV anxiety disorders (assessor masked). Secondary outcomes were parenting practices and parent mental health. Results: There was no significant difference in anxiety disorders between the intervention and control group during the three annual follow‐ups of the cohort in middle childhood (2015 43% vs. 41%, 2016 40% vs. 36%, 2017 27% vs. 30%, respectively; p's >.05). There were also no significant differences in child anxiety or depression symptoms (by child or parent report), parenting practices or parent mental health, between the intervention and control group during middle childhood. However, a priori interaction tests suggested that for children with anxious parents, early intervention attenuated risk for middle childhood internalising problems. Conclusions: An issue for population translation is low levels of parent engagement in preventive interventions. Initial effects of the Cool Little Kids parenting group programme in reducing shy/inhibited preschool children's internalising distress at school entry dissipated over time, perhaps due to low engagement. Future translational research on early prevention of internalising problems could benefit from screening preschool children in the population at higher risk (combining temperamental inhibition and parent distress) and incorporating motivational techniques to facilitate family engagement.

Background: The aim was to determine outcomes in the first year of school of a population‐delivered parenting program to prevent internalising problems in temperamentally inhibited preschool children and predictors of engagement in parenting groups. Method: Design: Randomised controlled trial. Setting: 307 preschool services across eight socio‐economically diverse government areas in Melbourne, Australia. Participants: 545 parents of inhibited 4‐year‐old children; 469 (86%) retained at two‐year follow‐up. Intervention: Cool Little Kids program. Primary outcomes were child internalising symptoms and anxiety disorders. Secondary outcomes were parenting, parent well‐being and engagement. Trial registration ISRCTN30996662 http://www.isrctn.com/ISRCTN30996662. Results: In the first year of school (M (SD) age 6.7 (0.4) years), child anxiety symptoms were reduced in the intervention versus control arm (PAS‐R M (SD): total 36.2 (17.2) versus 39.4 (18.5); adjusted difference −3.26, 95% CI −6.46 to −0.05, p =.047; specific fears 9.1 (6.2) versus 10.7 (6.8), adjusted difference −1.53; 95% CI −2.69 to −0.38, p =.009). However, there was little difference in broader child internalising (CMFWQ M (SD): 2.2 (0.5) versus 2.3 (0.6); adjusted difference −0.03, 95% CI −0.13 to 0.06, p =.489) or anxiety disorders (37.6% vs. 42.6%; adjusted OR 0.79, 95% CI 0.53 to 1.18, p =.242). Lower income, younger mothers, less educated and more culturally diverse fathers engaged less with the intervention. Continued skills practice was less frequent for parents of girls and in advantaged neighbourhoods. Conclusions: There were population effects of Cool Little Kids in the first year of school for anxiety symptoms but not disorders. Considering motivation techniques to engage subgroups of families would be helpful in translation research. [ABSTRACT FROM AUTHOR]

Purpose: Evidence suggests that children living in adversity are at greater risk of poorer language than their peers with the quality of parental interactions potentially mediating this association. Studies typically measure the mediatory impact of generic interaction styles making it difficult to discern which particular aspects of the interaction are facilitating language. This study aims to bridge this gap by identifying specific maternal behaviours associated with concurrent infant communication, in a cohort of 12-month old infants and their mothers experiencing adversity. Method: A total of 249 mother-infant free-play videos were collected from women experiencing adversity in Victoria and Tasmania, Australia. From those videos, specific maternal behaviours, infant communication acts and the interaction quality were coded. Result: Maternal verbal imitations uniquely predicted concurrent use of infant vocalisations, total words and unique words. Furthermore, the more fluent and connected the mother-infant dyad, the stronger the association between imitations and all three infant measures. Conclusion: Frequent use of maternal imitations, within highly connected mother-infant dyads, may help mediate the impact of adversity on early communication. This information is important for early years professionals working with at-risk populations in augmenting current knowledge of risk and protective factors related to early language.

Abstract: Background: Parent‐reported measures of early communication have limitations for use with infants experiencing adversity. Observational measures of early non‐verbal and verbal communicative behaviours and mother–child turn‐taking may provide a complementary method of capturing early communication skills for these children. Aims: To explore the predictive validity of verbal and non‐verbal behaviours and mother–child conversational turn‐taking (fluency and connectedness) at child age 12 months in relation to language measures at 24 and 36 months in a cohort of infants experiencing adversity. Methods & Procedures: Pregnant women experiencing adversity were recruited from maternity hospitals in Australia. At 12 months, 190 infants were videoed during mother–child free‐play. Verbal and non‐verbal communicative behaviours and fluency and connectedness were measured from the 12‐month videos. Predictive validity of 12‐month behaviours was calculated in relation to mean length of utterance and number of unique words at 24 months and Clinical Evaluation of Language Fundamentals Preschool—Second Edition (CELF‐P2) Core Language scores at 36 months. Outcomes & Results: All 12‐month behaviours had adequate specificity but poor sensitivity when compared with other predictive validity studies using published early language measures. However, in adjusted regression models, fluency and connectedness and verbal behaviours at 12 months predicted unique words at 24 months. Fluency and connectedness also predicted CELF‐P2 scores at 36 months. Conclusions & Implications: Findings reconfirm the difficulty in early identification of children at risk of later language difficulties. All 12‐month measures were more accurate at identifying those children who will have better language than those children who will not. As fluency and connectedness was the only measure to predict 24‐ and 36‐month language in adjusted regression models, it may be an important factor to consider when measuring early language skills for infants experiencing adversity. Future research could combine observational measures of early communication and fluency and connectedness with other predictors of language to try to increase prediction accuracy.

Objective: To determine whether a population-delivered parenting programme assists in preventing internalising problems at school entry for preschool children at-risk with temperamental inhibition. Methods: Design: a randomised controlled trial was used. Setting: the setting was 307 preschool services across eight socioeconomically diverse government areas in Melbourne, Australia. Participants: a total of 545 parents of inhibited 4-year-old children: 498 retained at 1-year follow up. Early intervention: Cool Little Kids parenting group programme was implemented. Primary outcomes: the primary outcomes were child DSM-IV anxiety disorders (assessor blind) and internalising problems. Secondary outcomes: the secondary outcomes were parenting practices and parent mental health. Results: At 1-year follow up (mean (standard deviation) age = 5.8 (0.4) years), there was little difference in anxiety disorders between the intervention and control arms (44.2% vs 50.2%; adjusted odds ratio = 0.86, 95% confidence interval = [0.60, 1.25], p = 0.427). Internalising problems were reduced in the intervention arm (Strengths and Difficulties Questionnaire: abnormal - 24.2% vs 33.0%; adjusted odds ratio = 0.56, 95% confidence interval = [0.35, 0.89], p = 0.014; symptoms - mean (standard deviation) = 2.5 (2.0) vs 2.9 (2.2); adjusted mean difference = -0.47, 95% confidence interval = [-0.81, -0.13], p = 0.006). Parents' participation in the intervention was modest (29.4% attended most groups, 20.5% used skills most of the time during the year). A priori interaction tests suggested that for children with anxious parents, the intervention reduced anxiety disorders and internalising symptoms after 1 year. Conclusion: Offering Cool Little Kids across the population for inhibited preschoolers does not impact population outcomes after 1 year. Effects may be emerging for inhibited children at highest risk with parent anxiety. Trial outcomes will continue into mid-childhood. [ABSTRACT FROM AUTHOR]

Variations in parenting have been suggested as contributing to a higher prevalence of language difficulties in children experiencing economic, environmental, and social adversity. Within these cohorts, the contribution of responsive and intrusive parenting to child language has been investigated; s pecific responsive and intrusive behaviors encapsulated within these parenting styles have yet to be fully examined. Additionally, the role of the mother-child dynamic in moderating mother-child associations has also not been explored. This study aimed to augment current research by identifying specific responsive and intrusive maternal behaviors associated with child language in a cohort experiencing adversity, as well as exploring the role of the fluency and connectedness of mother-child conversation in moderating associations ( n = 249). Specific behaviors and the fluency and connectedness of the mother-child interaction were coded from free-play videos at child age 12 months. Child language measures were derived from transcripts of free play at 24 months. Linear regression models were used to examine maternal-child associations. The moderating role of fluency and connectedness was then explored. Maternal imitations were positively associated with the child's total words; successful redirectives were negatively associated with the child's mean length of turn. Both associations were moderated by the fluency and connectedness of the interaction. [ABSTRACT FROM AUTHOR]

Purpose: To examine (1) the patterns of service use and costs associated with language impairment in a community cohort of children from ages 4–9 years and (2) the relationship between language impairment and health service utilisation. Method: Participants were children and caregivers of six local government areas in Melbourne participating in the community-based Early Language in Victoria Study (ELVS). Health service use was reported by parents. Costs were valued in Australian dollars in 2014, from the government and family perspectives. Depending on age, the Australian adapted Clinical Evaluation of Language Fundamentals – Pre-school, 2nd Edition (CELF-P2) or the CELF, 4th Edition (CELF4) was used to assess expressive and receptive language. Result: At 5, 7 and 9 years respectively 21%, 11% and 8% of families reported using services for speech and/or language concerns. The annual costs associated with using services averaged A$612 (A$255 to government, A$357 to family) at 5 years and A$992 (A$317 to government, A$675 to family) at 7 years. Children with persistent language impairment had significantly higher service costs than those with typical language. Conclusion: Language impairment in 4–9-year-old children is associated with higher use of services and costs to both families and government compared to typical language. [ABSTRACT FROM AUTHOR]

- Abstract
CGG repeat expansion >200 within FMR1, termed full mutation (FM), has been associated with promoter methylation, consequent silencing of gene expression and fragile X syndrome (FXS)-a common cause of intellectual disability and co-morbid autism. Unmethylated premutation (55-199 repeats) and FM alleles have been associated with fragile X related tremor/ataxia syndrome (FXTAS), a late onset neurodegenerative disorder. Here we present a 33-year-old male with FXS, with white matter changes and progressive deterioration in gait with cerebellar signs consistent with probable FXTAS; there was no evidence of any other cerebellar pathology. We show that he has tissue mosaicism in blood, saliva, and buccal samples for the size and methylation of his expanded alleles and a de novo, unmethylated microdeletion. This microdeletion involves a ~80 bp sequence in the FMR1 promoter as well as complete loss of the CGGrepeat in a proportion of cells. Despite FMR1 mRNA levels in blood within the normal range, the methylation and CGG sizing results are consistent with the diagnosis of concurrent FXS and probable FXTAS. The demonstrated presence of unmethylated FM alleles would explain the manifestation of milder than expected cognitive and behavioral impairments and early onset of cerebellar ataxia. Our case suggests that individuals with FXS, who manifest symptoms of FXTAS, may benefit from more detailed laboratory testing. [ABSTRACT FROM AUTHOR]

Mosaicism for FMR1 premutation (PM: 55-199 CGG)/full mutation (FM: >200 CGG) alleles or the presence of unmethylated FM (UFM) have been associated with a less severe fragile X syndrome (FXS) phenotype and fragile X associated tremor/ataxia syndrome (FXTAS)--a late onset neurodegenerative disorder. We describe a 38 year old male carrying a 100% methylated FM detected with Southern blot (SB), which is consistent with complete silencing of FMR1 and a diagnosis of fragile X syndrome. However, his formal cognitive scores were not at the most severe end of the FXS phenotype and he displayed tremor and ataxic gait. With the association of UFM with FXTAS, we speculated that his ataxia might be related to an undetected proportion of UFM alleles. Such UFM alleles were confirmed by more sensitive PCR based methylation testing showing FM methylation between 60% and 70% in blood, buccal, and saliva samples and real-time PCR analysis showing incomplete silencing of FMR1. While he did not meet diagnostic criteria for FXTAS based on MRI findings, the underlying cause of his ataxia may be related to UFM alleles not detected by SB, and follow-up clinical and molecular assessment are justified if his symptoms worsen.

We examined the lived experiences of twelve parents of low-progress readers. Parents were recruited from five state schools in Melbourne and each participated in individual interviews. Analyses revealed that most children received Reading Recovery which was the first and often only option. Parents were divided regarding satisfaction with their children's reading outcomes following this program. Sources of dissatisfaction included: a waiting list for commencement of intervention, the sudden cessation of Reading Recovery based on the 100-session limit, and Reading Recovery's theoretical orientation towards constructivist principles. Half the parents independently sought external reading intervention from conventional and nonconventional service providers. Moreover, many parents encountered a personal toll related to their children's reading difficulty. This study highlights the needs of parents who are important stakeholders in the management of low-progress readers. Our findings call for a more systematic, integrated and mindful approach between educators, policy makers and parents of low-progress readers. [ABSTRACT FROM AUTHOR]

Background: Evidence is required as to when and where to focus resources to achieve the greatest gains for children’s language development. Key to these decisions is the understanding of individual differences in children’s language trajectories and the predictors of those differences. To determine optimal timing we must understand if and when children’s relative language abilities become fixed. To determine where to focus effort we must identify mutable factors, that is those with the potential to be changed through interventions, which are associated with significant differences in children’s language scores and rate of progress. Methods: Uniquely this study examined individual differences in language growth trajectories in a population sample of children between 4 and 7 years using the multilevel model for change. The influence of predictors, grouped with respect to their mutability and their proximity to the child (least-mutable, mutable-distal, mutable-proximal), were estimated. Results: A significant degree of variability in rate of progress between 4 and 7 years was evident, much of which was systematically associated with mutable-proximal factors, that is, those factors with evidence that they are modifiable through interventions with the child or family, such as shared book reading, TV viewing and number of books in the home. Mutable-distal factors, such as family income, family literacy and neighbourhood disadvantage, hypothesised to be modifiable through social policy, were important predictors of language abilities at 4 years. Conclusions: Potential levers for language interventions lie in the child’s home learning environment from birth to age 4. However, the role of a family’s material and cultural capital must not be ignored, nor should the potential for growth into the school years. Early Years services should acknowledge the effects of multiple, cascading and cumulative risks and seek to promote child language development through the aggregation of marginal gains in the pre-school years and beyond.

The paper reports on a study designed to develop a risk model that can best predict single-word spelling in seven-year-old children when they were aged 4 and 5. Test measures, personal characteristics and environmental influences were all considered as variables from a community sample of 971 children. Strong concurrent correlations were found between single-word spelling and single-word reading while expressive language and, to a lesser extent, receptive language were less strongly correlated. Predictors of single-word spelling at ages 4 and 5 were dominated by child-related factors such as letter knowledge, a history of speech impairment and expressive language along with maternal word reading ability. Based on the strength of the predictive factors identified at both age 4 and 5, our results provide initial support for using a targeted model for screening pre-schoolers at risk of not mastering spelling in a timely manner.

Following a biopsychosocial model, the study investigated the role of child factors (gender, IQ), maternal factors (psychological distress, maternal education and vocabulary, maternal distress) and environmental factors (SES) in the relationship between language impairment and behaviour problems in preschool children. Participants were drawn from the Early Language in Victoria Study (ELVS) a prospective, longitudinal study examining the epidemiology and natural history of language impairment. The study reports on 1257 participants from the ELVS who completed questionnaires at 2 and 4 years and also completed face-to-face assessments at 4 years of age. Information was collected on child language, non-verbal cognition and social-emotional development; maternal vocabulary, maternal psychological distress and parent–child interaction; and SES. This study showed that language impairment is specifically associated with hyperactivity and peer problems but not anxiety and conduct problems at the preschool stage. Children with language impairment were at a higher risk for clinical levels of ‘abnormal’ behaviour which could lead to a psychiatric diagnosis than typically developing children. An examination of biopsychosocial variables associated with language and behaviour revealed that although language ability was a predictor of behaviour at both 2 years and 4 years of age, maternal distress was a stronger predictor of behaviour, with the association stronger for boys than for girls. Early intervention directed to children, especially boys, with language impairment deserves further attention, especially during the preschool period, in order to ameliorate the impact of language impairment on peer relationships and disruptive behaviour in later school years.

Background Language impairment (LI) in the preschool years is known to vary over time. Stability in the diagnosis of LI may be influenced by children's individual variability, the measurement error of commonly used assessment instruments and the cut-points used to define impairment. Aims To investigate the agreement between two different age-based versions of a language assessment instrument and the stability of the classification of LI using the two measures over a 12-month period. Methods & Procedures A total of 945 participants completed the Clinical Evaluation of Language Fundamentals (CELF-Preschool 2 or 4th Edn) at 4 and 5 years of age. Agreement and stability were analysed using Bland-Altman plots, correlation and odds ratios. Sensitivity and specificity were calculated for two thresholds of the CELF-P2 using the diagnostic category on the child's subsequent CELF-4. Outcomes & Results For all CELF scores, mean differences for the cohort between 4 and 5 years were within 1.5 scale score units. In contrast, at the individual level variability was found across the range of scores and was of a greater magnitude than previously reported. Stability in LI classification was low, with 36% of 5-year-olds with LI (defined as a standard score below -1.25) classified as typical at 4 years, even though odds ratios calculated from classifications at the two time points suggested that 4-year-olds with LI had 23 times greater odds than their typical peers to receive a diagnosis of LI at 5 years. The CELF-P2 did not demonstrate adequate levels of diagnostic accuracy for LI at 5 years: sensitivity of 64% and specificity of 92.9%. Conclusions Substantial variability across the entire range of possible CELF scores was observed in this community cohort between the ages of 4 and 5 years. The stability of LI classification was lower than that reported in previous research conducted primarily on smaller clinical cohorts. The current study's results suggest that the variability observed in developmental language pathways is the result of a combination of limitations in measurement instruments, individual children's abilities and the arbitrary nature of the boundaries defining LI.

Background Diagnostic criteria for attention deficit hyperactivity disorder (ADHD) suggest a range of difficulties in the pragmatic aspects of language, including excessive talking and interrupting others. Such difficulties have been periodically reported over several decades in studies on the language abilities of children with features of ADHD, yet a comprehensive review of the literature has been lacking. Aims This review aims to integrate evidence from several lines of research from 1979 to the present on pragmatic language difficulties in children with ADHD or symptoms of ADHD. Methods & Procedures A comprehensive search of empirical literature on pragmatic language in children with ADHD or symptoms of ADHD was conducted using PsycINFO and PubMed databases and through following up relevant references cited in articles. Literature was reviewed with respect to the nature and extent of pragmatic language difficulties in ADHD. Outcomes & Results Thirty studies met the review inclusion criteria, including recent questionnaire studies, observational studies of children's communication patterns, and studies of higher-level language comprehension and production. The studies indicate a consistent profile of pragmatic language impairments in children with features of ADHD, particularly in the areas of excessive talking, poor conversational turn-taking, and lack of coherence and organization in elicited speech. Conclusions & Implications Pragmatic language difficulties are common in children with features of ADHD. These difficulties are consistent with deficits in executive function that are thought to characterize ADHD, thus providing some support for the theory that executive function contributes to pragmatic language competency. As yet there is very little empirical evidence of specific relationships between particular aspects of pragmatic language and particular domains of executive function. Given the importance of pragmatic language competency for children's social and academic functioning, pragmatic language abilities should be considered during clinical assessment for ADHD and targeted for intervention.

- Abstract
This study examines potential predictors of 'precocious talking' (expressive language ⩾90th percentile) at one and two years of age, and of ' stability ' in precocious talking across both time periods, drawing on data from a prospective community cohort comprising over 1,800 children. Logistic regression was used to examine the relationship between precocious talking and the following potential predictors: gender, birth order, birth weight, non-English speaking background, socioeconomic status, maternal age, maternal mental health scores, and vocabulary and educational attainment of parents. The strongest predictors of precocity (being female and having a younger mother) warrant further exploration. Overall, however, it appears that precocity in early vocabulary development is not strongly influenced by the variables examined, which together explained just 2.6% and 1% of the variation at 1;0 and 2;0 respectively.

Background: Parent report instruments are frequently used for the identification of both 'at-risk' children and to support the diagnosis of communication delay. Whilst the evidence is strong for the accuracy of parent report of vocabulary between 2 and 3 years, there are fewer studies that have considered the ability of parents to report on early communication behaviours in 12-month-old infants. Aims: To investigate the validity of the underlying structure of the Communication and Symbolic Behaviour Scales-Developmental Profile (CSBS-DP) for each of the direct observation and parent reports of communication behaviour in infants at 12 months of age. Methods & Procedures: Participants were 1725 infants, already participating in a longitudinal study of language development, whose parents completed the Infant-Toddler Checklist from the CSBS-DP. Seven hundred and twenty-eight (728) of these infants also completed the Behaviour Sample from the CSBS-DP. The structure of the CSBS-DP was examined using confirmatory factor analyses (CFA) of the Behaviour Sample and the Infant-Toddler Checklist. Correlations between the Infant-Toddler Checklist and the Behaviour Sample on the total, composite, and subscale scores were also calculated. Outcomes & Results: Confirmatory factor analysis of the CSBS-DP Behaviour Sample replicated previous work conducted during the development of the instrument, but on a larger and younger cohort of Australian infants. The data provided support for at least three factors, broadly representing Social, Speech, and Symbolic communication skills, with some evidence that the speech factor could be further split into sub-factors representing Sounds and Words. There was support for a three-factor structure for the Infant-Toddler Checklist. Moderate correlations were found between results from the Behaviour Sample and the Infant-Toddler Checklist. Conclusions & Implications: As measures of early communication skill for young infants, the CSBS-DP Behaviour Sample and the Infant-Toddler Checklist are valid clinical tools for measuring constructs broadly representing Social, Speech, and Symbolic communication skills. The Speech composite in particular emerged as a strong factor under the Behaviour Sample. [ABSTRACT FROM AUTHOR]

- Abstract
The aim of this paper is to provide an overview of the methods and preliminary findings from the Early Language In Victoria Study (ELVS) a prospective, longitudinal study of child language impairment. Specifically, we provide a summary of early communication and vocabulary development and examine the contributions a range of risk factors and predictors make to these outcomes. The sample was a community-ascertained cohort of 1911 infants, recruited at 8 months and followed at ages 12 and 24 months. The main outcomes of interest were parent reported infant and toddler communication (Communication and Symbolic Behavior Scales, CSBS) and expressive vocabulary (MacArthur-Bates Communicative Development Inventories, CDI). Predictors included gender, preterm birth, birth weight, multiple birth, birth order, socioeconomic status, maternal mental health, maternal vocabulary and education, maternal age at birth of child, non-English-speaking background, and a family history of speech and/or language difficulties. Results demonstrated rapid development in communication skills measured by the three CSBS domains (social, speech and symbolic) and in vocabulary development (CDI). There was rapid growth in gesture use between 8 and 12 months and symbolic use of objects between 12 to 24 months. At approximately 24 months, 19.7% had delayed expressive vocabulary. Male gender and family history were associated with poorer outcomes on the CSBS and the CDI at 8, 12 and 24 months, although the regression models explained only a small amount of the variance in outcome. In summary we measured rapid growth in communication skills and vocabulary between 12 and 24 months, but the hypothesized early risk factors and predictors explained little of the variation in these outcomes. We conclude that the risk factors/predictors examined in this study therefore seem unlikely to be helpful in screening for early language delay. [ABSTRACT FROM AUTHOR]
