Associations between responsive parental behaviours in infancy and toddlerhood, and language outcomes at age 7 years in a population-based sample.

BACKGROUND: A wealth of evidence supports the important role high-quality parent-child interactions play in children's early language acquisition. However, the impact on later language outcomes remains unclear. AIMS: To examine the associations between responsive parental behaviours across the early years and child language outcomes at age 7 years with families from an Australian longitudinal cohort study (N = 1148, 50% female). METHODS & PROCEDURES: At child ages 12, 24 and 36 months, parents completed a self-report measure of responsive parental behaviours. Child language was directly assessed at age 7 using the Clinical Evaluation of Language Fundamentals, 4th edition (CELF-4), Australian Standardisation. Linear regression was used to examine associations between responsive parental behaviours from 12 to 36 months (consistently high, inconsistent and consistently low responsive parental behaviours at the three time points) and language scores at age 7 years. Adjusted models were run, including the following potential confounders: child sex; birth weight; birth order; maternal education; socio-economic disadvantage; non-English-speaking background; family history of speech-language problems; mother's vocabulary score; maternal mental health score; and mother's age at birth of child. A final adjusted model was run, including the potential confounder variables as well as adjusting for children's earlier language skills. OUTCOMES & RESULTS: Linear regression results showed children with parents who rated high on responsive parental behaviours at all three time points had higher mean language scores at age 7 than children whose parents reported low responsive parental behaviours across early childhood. This association attenuated after adjusting for earlier child language skills. CONCLUSIONS & IMPLICATIONS: Findings support the consistent use of responsive parental behaviours across the very early years of childhood to support long-term language outcomes. Findings also suggest that models of surveillance and support which monitor and assist families at multiple time-points over the early years are likely to be most effective for preventing ongoing language difficulties. WHAT THIS PAPER ADDS: What is already known on this subject There is extensive evidence consistently demonstrating the important contribution of aspects of parent-child interaction, specifically responsive parental behaviours, to children's language development. What this paper adds to the existing knowledge Understanding the cumulative benefit of responsive parent-child interactions across the very early years may help to inform preventive interventions and service delivery models for supporting young children's language development. This study demonstrates in a large, population-based cohort the contribution of consistency of responsive parental behaviours during infancy and toddlerhood to school-age language outcomes, accounting for other child, family and environmental factors. Capturing regular parent behaviours via self-report during the early years may be a more efficient and less costly method than parent-child interaction observations to monitor the home language-learning environment during routine developmental checks. What are the potential or actual clinical implications of this work? Findings support the need for surveillance of children and families in the early years, ensuring that intervention occurs when families need it most, that is, support is responsive to changing needs and that nuanced advice and support strategies are provided to activate positive developmental cascades. Capturing both parent behaviours and child language may assist clinicians to identify those families who may benefit from parent-child interaction intervention.

Effects of maternal depression on maternal responsiveness and infants' expressive language abilities.

High levels of maternal responsiveness are associated with healthy cognitive and emotional development in infants. However, depression and anxiety can negatively impact individual mothers' responsiveness levels and infants' expressive language abilities. Australian mother-infant dyads (N = 48) participated in a longitudinal study examining the effect of maternal responsiveness (when infants were 9- and 12-months), and maternal depression and anxiety symptoms on infant vocabulary size at 18-months. Global maternal responsiveness ratings were stronger predictors of infants' vocabulary size than levels of depression and anxiety symptoms. However, depression levels moderated the effect of maternal responsiveness on vocabulary size. These results highlight the importance of screening for maternal responsiveness-in addition to depression-to identify infants who may be at developmental risk. Also, mothers with elevated depression need support to first reduce their symptoms so that improvements in their responsiveness have the potential to be protective for their infant's language acquisition.

Parents' Perspectives of Family Engagement with Early Childhood Education and Care During the COVID-19 Pandemic.

The COVID-19 pandemic has created significant challenges for Early Childhood Education and Care (ECEC) services and families, impacting family access to services and their communication and engagement with educators. This study aimed to examine parents' perspectives of family engagement with ECEC services during the pandemic. Primary caregivers in Victoria at the time of recruitment (September-November 2020) were invited to participate. Of the 66 participants who completed an online survey, 25 also took part in semi-structured video call or phone interviews; qualitative findings from these interviews are reported in this paper. Four key themes were conceptualised using a reflexive thematic approach: (1) disruptions to ECEC access and attendance impacting on family routines and relationships, and child development; (2) barriers to family engagement; (3) ECEC educators' support of families and children during the pandemic; and (4) increased parental appreciation of the ECEC profession. Findings revealed that disruptions to ECEC access and routines during the pandemic adversely impacted family engagement, and child learning and social-emotional wellbeing for some families. These were aggravated by other stressors, including increased parental responsibilities in the home, financial and health concerns, and changed work conditions. Findings also demonstrated successful methods used by educators to maintain communication and connections with families. Importantly, parents expressed increasing appreciation of the profession and an increased awareness of the value of family involvement in children's learning. Learnings regarding strategies for effective and alternative ways of engaging families are discussed.

Developing Preschool Language Surveillance Models - Cumulative and Clustering Patterns of Early Life Factors in the Early Language in Victoria Study Cohort.

BACKGROUND: Screening and surveillance of development are integral to ensuring effective early identification and intervention strategies for children with vulnerabilities. However, not all developmental skills have reliable screening processes, such as early language ability. METHOD: We describe how a set of early life factors used in a large, prospective community cohort from Australia are associated with language abilities across the preschool years, and determine if either an accumulation of risk factors or a clustering of risk factors provide a feasible approach to surveillance of language development in preschool children. RESULTS: There were 1,208 children with a 7-year language outcome. The accumulation of early life factors increased the likelihood of children having low language skills at 7-years. Over a third of children with typical language skills (36.6%) had ≤ two risks and half of the children with low language (50%) had six or more risks. As the number of factors increases the risk of having low language at 7-years increases, for example, children with six or more risks had 17 times greater risk, compared to those with ≤ two risks. Data collected from 1,910 children at 8- to 12-months were used in the latent class modeling. Four profile classes (or groups) were identified. The largest group was developmentally enabled with a supportive home learning environment (56.2%, n = 1,073). The second group was vulnerable, both developmentally and in their home learning environment (31.2%, n = 596); the third group was socially disadvantaged with a vulnerable home learning environment (7.4%, n = 142); the final group featured maternal mental health problems and vulnerable child socio-emotional adjustment (5.2%, n = 99). Compared to developmentally enabled children, the risk of low language at 7-years was greater for children in the three other groups. CONCLUSION: The cumulative and cluster risk analyses demonstrate the potential to use developmental surveillance to identify children within the first years of life who are at risk of language difficulties. Importantly, parent-child interaction and the home learning environment emerged as a consistent cluster. We recommend they be adopted as the common focus for early intervention and universal language promotion programs.

Validation of a measure of parental responsiveness: Comparison of the brief Parental Responsiveness Rating Scale with a detailed measure of responsive parental behaviours.

Parental responsiveness is vital for child language development. Its accurate measurement in clinical settings could identify families who may benefit from preventative interventions; however, coding of responsiveness is time-consuming and expensive. This study investigates in a clinical context the validity of the Parental Responsiveness Rating Scale (PaRRiS): a time- and cost-effective global rating scale of parental responsiveness. Child health nurse (CHN) PaRRiS ratings are compared to a detailed coding of parental responsiveness. Thirty parent-child dyads completed an 8-min free-play session at their 27-month health review. CHNs rated the interaction live using PaRRiS. Videos of these interactions were then blindly coded using the more detailed coding system. PaRRiS ratings and detailed codings were compared using correlational analysis and the Bland-Altman method. PaRRiS and the detailed coding showed a moderate-strong correlation (rs (28) = 0.57, 95% CI [0.26, 0.77]) and high agreement (Bland-Altman). CHNs using PaRRiS can capture parental responsiveness as effectively as trained clinicians using detailed coding. This may allow (1) increased accuracy and efficiency in identifying toddlers at risk for long-term language difficulties; (2) more accurate allocation to speech and language therapy (SLT) services; (3) decreased burden on SLT resources by empowering CHNs to make more informed referral decisions.

Happy Talk: A pilot effectiveness study of a targeted-selective speech-language and communication intervention for children from areas of social disadvantage.

BACKGROUND: Despite the public health implications of language difficulties associated with social disadvantage, there is a dearth of effectiveness studies investigating the effects of targeted speech and language programmes in this area. AIMS: To determine the effects of a targeted selective community-based child language intervention programme (Happy Talk), which simultaneously engaged with parents and early childhood educators, in the Republic of Ireland. METHODS & PROCEDURES: A mixed methods methodology was applied with quantitative outcome and qualitative process data collected. Effectiveness was examined using a quasi-experimental single blind study design comparing Happy Talk with 'usual care' across four preschools. Qualitative process data were also gathered to examine the acceptability and feasibility of the Happy Talk approach in practice, and to identify factors to improve the probability of successful wider implementation. Child language (PLS-5) and quality-of-life measures were administered pre- and immediately post- the 11-week intervention. Responsiveness was assessed as the parental outcome, and the oral language environment of preschools was measured using the Communication Supporting Classroom Observation Tool (CSCOT). Retrospective acceptability was analysed with reference to the theoretical framework of acceptability (v 2). OUTCOMES & RESULTS: Pre-/post-expressive and composite language scores were collected for 58 children, and receptive scores for 54 children. Multiple linear regression revealed significant intervention effects for comprehension and total language with large and moderate effect sizes, respectively (0.60 and 0.46 SD). No significant effect was shown for parental responsiveness. No effects were found for the preschool environment or children's quality of life. Preschool staff deemed the programme to be an acceptable method of enhancing children's speech and language skills and rated the intervention positively. CONCLUSIONS & IMPLICATIONS: The Happy Talk pilot effectiveness trial shows that comprehension can be improved (with a large effect) in preschool children from areas of social disadvantage, following an 11-week intervention, in which parents and preschool staff are simultaneously engaged. The ecological validity of the programme, as well as feasibility and acceptability to staff, make it a suitable programme to be delivered at scale. WHAT THIS PAPER ADDS: What is already known on the subject Up to 50% of children from socially disadvantaged areas enter preschool with speech and language difficulties. The majority of intervention studies are (1) researcher led; (2) efficacy trials carried out in ideal conditions; and (3) focus on working with parents or early childhood educators rather than engaging with both groups simultaneously. Many studies omit child language outcomes, and those that include them tend to show relatively modest effects for expressive language and negligible effects for receptive language. What this paper adds to existing knowledge This pilot study shows that the Happy Talk programme, which is embedded in the community and which simultaneously engages with parents and early childhood educators, is highly effective in improving children's receptive language skills. These findings are particularly important in the context of (1) the study taking place in real world conditions; and (2) the programme being designed and refined by speech and language therapy services, rather than one which is researcher led. What are the potential or actual clinical implications of this work? Implementing an 11-week targeted selective community-based language intervention can result in a large positive effect on receptive language for children from areas of social disadvantage. The study findings highlight the importance of embedding intervention programmes in the community and of simultaneously engaging with parents and preschool staff.

Early Childhood Educators' Wellbeing During the COVID-19 Pandemic.

The importance of Early Childhood (EC) educators' wellbeing has been brought into sharp focus during the COVID-19 pandemic, as educators have navigated numerous additional stressors while providing education and care services for some children and ongoing support for many others learning at home. This study aimed to explore the impact of the pandemic on EC educators' wellbeing and educator-child relationships, as growing evidence shows the influence of these factors on children's developmental outcomes. In July 2020, members of a Research Network of EC Professionals-who previously identified educator wellbeing as a priority issue-were invited to participate in an online survey. The survey included two published, validated scales: the Early Childhood Professional Wellbeing scale (ECPW) and the Student-Teacher Relationship Scale (modified). Survey items about educators' experiences during the pandemic were also included. Two hundred and thirty-two EC educators from across Australia completed the survey, mostly from Victoria where lockdowns were most severe. Linear regression analysis demonstrated stronger professional wellbeing was associated with less conflict in educator-child relationships and lower risk of staff turnover. This was more likely to be experienced by senior or more experienced staff. Although a negative impact of COVID-19 was reported, ECPW scores were relatively high, and organizational structures supporting professional wellbeing were most strongly associated with lower risk of turnover (r = 0.63, p < 0.001). Findings highlight that supporting EC educators' wellbeing is essential for workforce retention, and for promoting quality educator-child relationships which are central to young children's learning and development.

Prevalence of language and pre-literacy difficulties in an Australian cohort of 5-year-old children experiencing adversity.

BACKGROUND: Early reading success is predicated on language and pre-literacy skills. Children who are behind their peers in language and pre-literacy development before formal schooling are less likely to be proficient beginner readers, and difficulties may persist throughout primary school and beyond. We know children experiencing adversity are at greater risk of early language and pre-literacy difficulties; we do not know the prevalence of these difficulties in an Australian adversity context. AIMS: To investigate the prevalence and co-occurrence of language and pre-literacy difficulties in a cohort of Australian 5-year-old children experiencing social adversity. METHODS & PROCEDURES: Data were drawn from a large Australian community-based trial of nurse home visiting (right@home), which aimed to support women experiencing social adversity from pregnancy until their child turned 2 years of age. Social adversity was determined by two of more risk factors: young pregnancy, not living with another adult, no support, poorer health, current smoker, long-term illness, anxious mood, not finishing high school, no household income and no previous employment. Children whose mothers were enrolled in the control group (receiving usual maternal and child healthcare) were included in the current study (n = 359). Language and pre-literacy skills were measured at age 5 using the Clinical Evaluation of Language Fundamental Preschool-Second Edition (CELF-P2) and the School Entry Alphabetic and Phonological Awareness Readiness Test (SEAPART). Language difficulties were defined as ≥ 1.25 standard deviations (SD) below the Australian normative mean on CELF-P2 Core Language scores. Pre-literacy difficulties were defined as children scoring in the Beginner (versus Developing or Competent) criterion-referenced level on the SEAPART First Sound Identification and/or Alphabet Letter Identification subtests. Co-occurrence of language and pre-literacy difficulties was also determined. OUTCOMES & RESULTS: At the 5-year follow-up, 201/359 (56%) children were assessed (mean age = 5.1 years, SD = 0.1). Mean Core Language score for this cohort (91.8, SD = 15.9) was 0.54 SD below the normative mean (100, SD = 15). The proportion of children presenting with language difficulties was 24.9%. Regarding pre-literacy skills, 43.8% of children were 'Beginner' for identifying first sounds and 58.6% for identifying alphabet letters/sounds. There was also considerable overlap whereby 76.7% of children with language difficulties also exhibited pre-literacy difficulties. CONCLUSIONS & IMPLICATIONS: This is the first empirical Australian-based study highlighting the high prevalence and co-occurrence of language and pre-literacy difficulties in preschool children experiencing social adversity. Clinicians should be aware of co-morbid language and pre-literacy difficulties in disadvantaged populations and consider both areas during assessment and intervention planning. What this paper adds What is already known on the subject The prevalence of language and literacy difficulties is substantially higher in cohorts experiencing social adversity when compared with more advantaged families. There is some evidence that adversity also contributes to pre-literacy difficulties, but less is known here. What this paper adds to existing knowledge This study presents new prevalence data showing high rates of language and pre-literacy difficulties for 5-year-old children experiencing adversity within an Australian context. It is the first to explore these skills in a large cohort of pre-schoolers recruited from community settings in Australia. What are the potential or actual clinical implications of this work? In this cohort experiencing adversity, most children who presented with language difficulties likewise exhibited pre-literacy difficulties. This concordance reflects how early oral language and pre-literacy skills develop together. Clinicians should assess both skills in preschool populations-especially those working with children experiencing adversity-to ensure all children have strong foundations to become proficient beginner readers.

Cultural and Linguistic Practice with Children with Developmental Language Disorder: Findings from an International Practitioner Survey.

BACKGROUND: The cultural and language diversity across many European countries presents a range of challenges and opportunities for speech and language therapists and other practitioners working with children with developmental language disorders (DLD) and their families. OBJECTIVE: The aim of this study was to explore practitioners' perceptions of cultural and linguistic differences in response to children with DLD across different countries. METHODS: A survey was developed by practitioners and researchers working with children with DLD across Europe and beyond as part of the work of Cost Action IS1406. Data from 1,358 practitioners from 8 European countries - Ireland, UK, Bulgaria, Poland, Croatia, Spain, Norway and Sweden - and 2 neighbour countries - Turkey and Lebanon - were included in the present analyses, which address two groups of questions. The first focuses on practitioners' perceptions of the way that parents think about cultural differences and their relationship to language development in their children. The second concerns the extent to which practitioners consider themselves to have the skills to work with children from other cultures and using different languages. RESULTS/CONCLUSIONS: Most countries present a similar profile with intermediate results about their perception of cultural issues, but Lebanon and Turkey are the group with the most positive responses. In terms of bilingual issues most practitioners indicated that they only worked in their country's primary language. The only country where this was not the case was Lebanon. Professionals from Spain and Lebanon form a subgroup in terms of their confidence to work with different cultural/language groups. The paper highlights both the universal importance of cultural and linguistic competence in managing young children's needs and indicates that in most cases professionals do not think they have the necessary expertise to work with cultural and linguistic diversity.

Expectations and experiences of parents taking part in parent-child interaction programmes to promote child language: a qualitative interview study.

BACKGROUND: Parent-child interaction therapies are commonly used by speech and language therapists (SLTs) when providing services to young children with language learning difficulties. However, the way parents react to the demands of such interventions is clearly important, especially for those from socially disadvantaged backgrounds. Parents play a central role in the therapy process so to ensure parent engagement, and to maximize intervention effectiveness, parents' views must be considered. AIMS: To explore the expectations and experiences of parents from socially disadvantaged backgrounds who had taken part in a parent-child interaction programme aimed at promoting language development in 2-3 year olds with language difficulties. METHODS & PROCEDURES: The sample included parents who had a child aged 2-3 years and had attended a parent-child interaction programme to promote their child's language development. Parents were eligible to take part if they were living in the 30% most deprived areas in a city in the North of England that constituted the study site. Ten parents participated in a qualitative semi-structured face-to-face interview in the home. Framework analysis was used to analyse the interview transcripts. OUTCOMES & RESULTS: Parents' expectations before taking part in parent-child interaction interventions contribute to how they may engage throughout the intervention process. Barriers include parents' uncertainty about the nature of the intervention and differing attitudes regarding intervention approaches and strategies. Facilitators during the intervention process include gaining support from other parents, reassurance from the SLT regarding their child's language development, and their own ability to support their child's language learning, as well as increased confidence in how they support their child's development. CONCLUSIONS & IMPLICATIONS: Parents respond very differently to parent-child interaction intervention for children with language difficulties, depending on their expectations and attitudes towards intervention. Thus, it is critical that these different perspectives are understood by practitioners before intervention commences to ensure successful engagement. What this paper adds What is already known on this subject Parent-child interaction interventions are widely used to promote child language development. Parents play a central role in the therapy process of such interventions, so to maximize effectiveness, parents must be appropriately 'engaged' in that intervention. This involves attending, fully participating and having appropriate attitudinal and/or emotional involvement. The reciprocal nature of engagement means that parents are more likely to become engaged in intervention over time when they are supported by their SLT. What this paper adds to existing knowledge Parental expectations about the intervention process vary considerably and often need to be negotiated before the start of intervention. Reassurance and supporting positive attitudes to co-working with their SLT may be particularly important for families living with social disadvantage. Supporting parent engagement in parent-child interaction programmes can contribute to the parents' capability to continue implementing language-promoting strategies outside the intervention context and beyond the end of therapy. What are the potential or actual clinical implications of this work? Parents have different expectations regarding programme involvement. Therefore, having a two-way, open dialogue between parents and SLTs from the beginning is clearly important, not only as a way of sharing information but also to build on parents' understanding of what the intervention will involve and trust that the SLT will be able to deliver the intervention in collaboration with the parent. SLTs can enhance parent engagement by supporting parents to feel confident and providing reassurance in terms of their child's development and how they can support their child's language learning.

Protocol for the Adaptation of a Direct Observational Measure of Parent-Child Interaction for Use With 7-8-Year-Old Children.

OBJECTIVE: Parenting sensitivity and mutual parent-child attunement are key features of environments that support children's learning and development. To-date, observational measures of these constructs have focused on children aged 2-6 years and are less relevant to the more sophisticated developmental skills of children aged 7-8 years, despite parenting being equally important at these ages. We undertook a rigorous process to adapt an existing observational measure for 7-8-year-old children and their parents. This paper aimed to: (i) describe a protocol for adapting an existing framework for rating parent-child interactions, (ii) determine variations in parents' sensitive responding and parent-child mutual attunement ('positive mutuality') by family demographics, and (iii) evaluate the psychometric properties of the newly developed measure (i.e., inter-rater reliability, construct validity). METHOD: Parent-child dyads completed one home visit, including a free-play observation and parent questionnaire. Dyads were provided with three toy sets: LEGO® Classic Box, Classic Jenga®, and animal cards. The Coding of Attachment-Related Parenting (CARP) was adapted for use with 7-8-year-old children, and rating procedures were streamlined for reliable use by non-clinician/student raters, producing the SCARP:7-8 Years. Trained staff rated video-recorded observations on 11 behaviors across two domains (five for parents' sensitive responding, six for parent-child positive mutuality). RESULTS: Data were available for 596 dyads. Consistently strong inter-rater agreement on the 11 observed behaviors was achieved across the 10-week rating period (average: 87.6%, range: 71.7% to 96.7%). Average ICCs were 0.77 for sensitive responding and 0.84 for positive mutuality. These domains were found to be related but distinct constructs (r = 0.49, p < 0.001). For both domains, average ratings were strongly associated with the main toy used during the observation (p < 0.001, highest: cards, lowest: LEGO®). Adjusted multivariate linear regression models (accounting for toy choice) revealed that less sensitive responding was associated with younger parent (p = 0.04), male parent (p = 0.03), non-English speaking background (p = 0.04), and greater neighborhood disadvantage (p = 0.02). Construct validity was demonstrated using six parent-reported psychosocial and parenting measures. CONCLUSION: The SCARP: 7-8 Years shows promise as a reliable and valid measure of parent-child interaction in the early school years. Toy selection for direct observation should be considered carefully in research and practice settings.

Training community health nurses to measure parent-child interaction: a mixed-methods study.

BACKGROUND: This study aims to determine whether the Parental Responsiveness Rating Scale (PaRRiS) completed at child age 24-30 months can be used by community child health nurses (CCHNs) to reliably measure the quality of parent-child interactions in practice. METHODS: A mixed-methods design was used involving CCHNs working in public health settings. Five CCHNs recruited from the North-East of England were trained to use PaRRiS. Thirty parent-child dyads attending their routine 24-30-month check were observed. Nurses rated parent-child dyads during 5 min of free-play using PaRRiS. The free-play sessions were video recorded and rated blind by the first author to the nurse observation. Semi-structured phone interviews were conducted with the five CCHNs once observations of parent-child interactions were complete. Interviews were audio-recorded, transcribed, anonymized and thematically analyzed. RESULTS: Two-thirds of participating parents were mothers. Half the families (15/30) were from the 10% most deprived areas based on the English Index of Multiple Deprivation. The average PaRRiS score was 3.03 [standard deviation (SD) = 0.8; all ratings were <5.0]. Reliability between the first author ('gold standard') and CCHNs was excellent [Intra-class correlation coefficient (ICC): 0.85; 95% confidence interval (CI): 0.67-0.93]. CCHNs found PaRRiS aligned well with current practice and was acceptable to parents. There was no evidence of a relationship between social disadvantage and PaRRiS scores. CONCLUSIONS: With further development and evaluation work, PaRRiS could potentially be incorporated into existing universal health services to provide child health nurses with an additional tool for identifying families most likely to be in need of parent-child interaction interventions.

Working with the parents and families of children with developmental language disorders: An international perspective.

BACKGROUND: The relationship between parental input and child language development has had a complex history. It has become clear that indirect parent training for the parents of children with delayed language development is an important feature of interventions offered by speech and language therapists in the anglophone countries. Yet we know less about how this type of approach is realised in other countries. METHODS: In this paper we report the results of a survey of practice undertaken as part of the work of COST Action IS1406, a European Union (EU) funded research network. The focus of this paper is specifically on parent-related questions and responses referring to children under the age of twelve. The survey was devised by members of the Action and circulated electronically during the summer of 2017. In all, 4024 practitioners responded from 60 countries, the majority of whom came from EU member countries. FINDINGS: Respondents to the survey indicated that indirect therapy is commonly carried out via the parent in the early years and via teachers later. A range of professional groups, in addition to speech and language therapists, is likely to adopt this approach; including teachers, pedagogues and psychologists. A variety of interventions is reported, some of which have a reasonable evidence-base underpinning them. It is interesting to see the widespread involvement of fathers and other family members in interventions. Finally, the fact that practitioner characteristics (age, experience, location of practice etc.) are not related to the use of indirect techniques points to the universal recognition of the value of these approaches. CONCLUSIONS: Despite the very different traditions in the practice of intervention across countries, there is clearly a widespread recognition of the importance of indirect approaches to intervention and specifically those focusing on parents. The mixture of family members being involved in interventions is a very promising indication of the role sharing commonly associated with the contemporary family. Yet the number of specific intervention approaches identified is relatively small given the number of respondents. There is a need for a better understanding of what exactly practitioners are doing when they involve parents in intervention or carry out parent-child interaction interventions and how well these interventions work in routine practice. This also has implications for the application of evidence-based practice and the precise nature of the interventions concerned (advice to parents, video interaction training etc.).

Associations between early maternal behaviours and child language at 36 months in a cohort experiencing adversity.

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.

A replicable, low-burden mechanism for observing, recording, and analysing mother-child interaction in population research.

BACKGROUND: There is growing evidence that specific styles of parent-child interaction benefit child development, particularly child language development. Direct observational techniques help clarify the behaviours and styles within parent-child interactions that may influence child language outcomes; however, these techniques tend to be labour-intensive and costly. We report on the development of a replicable, low-burden mechanism for observing and coding specific maternal linguistic behaviours in a population-based cohort of 2-year-olds. METHODS: The coding scheme was developed as part of a prospective, longitudinal study examining the associations between maternal responsive behaviours and child language outcomes in slow-to-talk toddlers. In the first phase of the study, three coding systems were tested by coding five sample parent-toddler interactions and then comparing them based on (a) the ease of method and thus likely intrarater and interrater reliability and (b) the number of data points. The second phase was to demonstrate how the chosen method could be used in practice with a large at-risk group of toddlers. RESULTS: Of the three coding systems explored, the Observer® XT software was selected for ease of use and because detailed coding of free-play videos could be achieved in close to real time. Intrarater and interrater reliability were established in 251 mother-child free-play videos, producing high intraclass correlation coefficients of 0.95 to 0.99 for the six behaviours. CONCLUSIONS: The study provides evidence that numerous parent-child interactions can be rigourously yet efficiently coded without substantial information loss. The observational mechanism in the current study has been fully developed and is shown to be feasible for research purposes focusing on parent-toddler interactions. However, further testing of the observational mechanism is required to examine whether the same results could be produced if coding was conducted "live" and for shorter duration thereby making it readily useable for clinicians.

Associations between maternal responsive linguistic input and child language performance at age 4 in a community-based sample of slow-to-talk toddlers.

BACKGROUND: In a community sample of slow-to-talk toddlers, we aimed to (a) quantify how well maternal responsive behaviors at age 2 years predict language ability at age 4 and (b) examine whether maternal responsive behaviors more accurately predict low language status at age 4 than does expressive vocabulary measured at age 2 years. DESIGN OR METHODS: Prospective community-based longitudinal study. At child age 18 months, 1,138 parents completed a 100-word expressive vocabulary checklist within a population survey; 251 (22.1%) children scored ≤20th percentile and were eligible for the current study. Potential predictors at 2 years were (a) responsive language behaviors derived from videotaped parent-child free-play samples and (b) late-talker status. Outcomes were (a) Clinical Evaluation of Language Fundamentals-Preschool Second Edition receptive and expressive language standard score at 4 years and (b) low language status (standard score > 1.25 standard deviations below the mean on expressive or receptive language). RESULTS: Two hundred eight (82.9% of 251) participants were retained to age 4. In adjusted linear regression analyses, maternal expansions predicted higher receptive (p < 0.001, partial R2  = 6.5%) and expressive (p < 0.001, partial R2  = 7.7%), whereas labels predicted lower receptive (p = 0.01, partial R2  = 2.8%) and expressive (p = 0.007, partial R2  = 3.5%) language scores at 4. The logistic regression model containing only responsive behaviors achieved "fair" predictive ability of low language status at age 4 (area under curve [AUC] = 0.79), slightly better than the model containing only late-talker status (AUC = 0.74). This improved to "good" predictive ability with inclusion of other known risk factors (AUC = 0.82). CONCLUSION: A combination of short measures of different dimensions, such as parent responsive behaviors, in addition to a child's earlier language skills increases the ability to predict language outcomes at age 4 to a precision that is approaching clinical value. Research to further enhance predictive values should be a priority, enabling health professionals to identify which slow-to-talk toddlers most likely will or will not experience later poorer language.

Predictive validity of verbal and non-verbal communication and mother-child turn-taking at 12 months on language outcomes at 24 and 36 months in a cohort of infants experiencing adversity: a preliminary study.

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.

EHLS at School: school-age follow-up of the Early Home Learning Study cluster randomized controlled trial.

BACKGROUND: Targeted interventions during early childhood can assist families in providing strong foundations that promote children's health and wellbeing across the life course. There is growing recognition that longer follow-up times are necessary to assess intervention outcomes, as effects may change as children develop. The Early Home Learning Study, or 'EHLS', comprised two cluster randomized controlled superiority trials of a brief parenting intervention, smalltalk, aimed at supporting parents to strengthen the early childhood home learning environment of infants (6-12 months) or toddlers (12-36 months). Results showed sustained improvements in parent-child interactions and the home environment at the 32 week follow-up for the toddler but not the infant trial. The current study will therefore follow up the EHLS toddler cohort to primary school age, with the aim of addressing a gap in literature concerning long-term effects of early childhood interventions focused on improving school readiness and later developmental outcomes. METHODS: 'EHLS at School' is a school-aged follow-up study of the toddler cluster randomized controlled trial (n = 1226). Data will be collected by parent-, child- and teacher-report questionnaires, recorded observations of parent-child interactions, and direct child assessment when children are aged 7.5 years old. Data linkage will provide additional data on child health and academic functioning at ages 5, 8 and 10 years. Child outcomes will be compared for families allocated to standard/usual care (control) versus those allocated to the smalltalk program (group program only or group program with additional home coaching). DISCUSSION: Findings from The Early Home Learning Study provided evidence of the benefits of the smalltalk intervention delivered via facilitated playgroups for parents of toddlers. The EHLS at School Study aims to examine the long-term outcomes of this initiative to determine whether improvements in the quality of the parent-child relationship persist over time and translate into benefits for children's social, academic and behavioral skills that last into the school years. TRIAL REGISTRATION: 8 September 2011; ACTRN12611000965909 (for the original EHLS).

Concurrent associations between maternal behaviours and infant communication within a cohort of women and their infants experiencing adversity.

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.
