Purpose: We investigated the effectiveness of a highly individualized morphosyntactic intervention using the SHAPE CODING™ system delivered at different dosages.

Method: Eight children with developmental language disorder aged 8;0-10;10 (years;months) received 10 hr of explicit individualized intervention for morphosyntax delivered in 30-min individual sessions once per week for 20 weeks. Following at least four baseline probe tests, two grammatical targets per session received explicit instruction until they reached criterion (90%), when the next target was introduced.

Objective: Investigating the impact of early childhood ventilation tube insertion (VTI) on long-term language outcomes.

Design: Longitudinal cohort study.

Setting: A total of 2900 pregnant women participated in the Raine Study between 1989 and 1991 in Western Australia, and 2868 children have been followed up.

Background: Developmental language disorder (DLD) is one of the most common neurodevelopmental conditions. Due to variable rates of language growth in children under 5 years, the early identification of children with DLD is challenging. Early indicators are often outlined by speech pathology regulatory bodies and other developmental services as evidence to empower caregivers in the early identification of DLD.

To explore the clinical potential of grammaticality judgement tasks, this study investigated whether a Grammaticality Judgment Task (GJT) of inflectional morphology could differentiate between a clinically selected sample of children with DLD and children in mainstream (i.e. regular education) schools.

Purpose: The aim of this research note is to encourage child language researchers and clinicians to give careful consideration to the use of domain-specific tests as a proxy for language; particularly in the context of large-scale studies and for the identification of language disorder in clinical practice.

Method: We report on data leveraged through the prospective Raine Study cohort. Participants included 1626 children aged 10 years ( = 104 with developmental language disorder [DLD] and  = 1522 without DLD).

Aim: This study sought to determine the prevalence of Developmental Language Disorder (DLD) in Australian school-aged children and associated potential risk factors for DLD at 10 years.

Methods: This study used a cross-sectional design to estimate the prevalence of DLD in Generation 2 of the prospective Raine Study. Participants included 1626 children aged 10 years with available language data.

Aims: This study compared two dose frequency conditions of an explicit intervention with 50 trials per session designed to improve past tense marking in early school-aged children with developmental language disorder (DLD). The influence of allomorphs on intervention effects was also examined.

Methods: Data from previously conducted intervention studies were combined and analysed.

Previous research has established that children with developmental language disorder (DLD) have difficulties producing inflectional morphology, in particular, finiteness marking. However, other categories of inflectional morphology, such as possessive nominal inflection remain relatively unexplored. Analyses of the characteristics for marking inflection, such as allomorphic categories, may increase our understanding of patterns within disordered grammar to inform the design of interventions and target selection.

Purpose The aim of the study was to evaluate the efficacy of a theoretically motivated explicit intervention approach to improve regular past tense marking for early school-age children with developmental language disorder (DLD). Method Twenty-one children with DLD (ages 5;9-6;9 [years;months]) were included in a crossover randomized controlled trial (intervention, = 10; waiting control, = 11). Intervention included once-weekly sessions over 10 weeks using the SHAPE CODING system, in combination with a systematic cueing hierarchy to teach past tense marking.

Purpose The aim of the study was to examine whether otitis media (OM) in early childhood has an impact on language development in later childhood. Methods We analyzed data from 1,344 second-generation (Generation 2) participants in the Raine Study, a longitudinal pregnancy cohort established in Perth, Western Australia, between 1989 and 1991. OM was assessed clinically at 6 years of age.

Purpose This study evaluated the efficacy of an explicit, combined metalinguistic training and grammar facilitation intervention aimed at improving regular past tense marking for nine children aged 5;10-6;8 (years;months) with developmental language disorder. Method This study used an ABA across-participant multiple-baseline single-case experimental design. Participants were seen one-on-one twice a week for 20- to 30-min sessions for 10 weeks and received explicit grammar intervention combining metalinguistic training using the SHAPE CODING system with grammar facilitation techniques (a systematic cueing hierarchy).

Unlabelled: Purpose of the article: To review the use of outcome measures, across the domains of activity, participation, and environment, within multidisciplinary early childhood intervention services.

Materials And Methods: A systematic literature search was undertaken that included four electronic databases: Medline, CINAHL, EMBASE, and the Cochrane Library and Cochrane Database of Systematic Review. Inclusion criteria were age 0-24 months, having or at risk of a developmental disability, in receipt of multidisciplinary early childhood intervention services, and included outcome measures across all domains of the International Classification of Functioning-Child & Youth (ICF-CY).

Purpose: The aim was to identify the views of Australian and New Zealand health professionals regarding the support needs of people with head and neck cancer (HNC) and their families and current gaps in service delivery.

Methods: A modified Delphi process assessed support needs of people with HNC following acute medical management. A systematic review of the literature was used to develop items relevant to seven key concepts underpinning the psychological experience of living with HNC.

There has been limited research to date into methods for increasing people's intentions to use omega-3 polyunsaturated fatty acids (n-3 PUFA), which have been linked with decreased risk of suffering from numerous major diseases. The present study employed a cross-sectional design with 380 university students, employees, and visitors to investigate the efficacy of the protection motivation (PM) theory and the ordered protection motivation (OPM) theory, to predict behavioral intention to consume omega-3 rich foods and dietary supplements. Analysis of model fit indicated that both the PM model and the OPM model adequately represented the structural relationships between the cognitive variables and intention to consume n-3 PUFA.
