Purpose The aim of this study was to examine the degree to which quantitative aspects of dosage (dose, dose frequency, and total intervention duration) have been examined in intervention studies for children with developmental language disorder (DLD). Additionally, to establish the optimal quantitative dosage characteristics for phonology, vocabulary, and morphosyntax outcomes. Method This registered review (PROSPERO ID CRD42017076663) adhered to PRISMA guidelines. Search terms were included in seven electronic databases. We included peer-reviewed quasi-experimental, randomized controlled trial or cohort analytical studies, published in any language between January 2006 and May 2020. Included articles reported on participants with DLD ( M = 3–18 years); oral language interventions with phonology, vocabulary, or morphosyntax outcomes; and experimental manipulation or statistical analysis of any quantitative aspect of dosage. Studies were appraised using the Cochrane risk-of-bias tool. Results Two hundred forty-four articles reported on oral language interventions with children with DLD in the domains of interest; 13 focused on experimentally/statistically manipulating quantitative aspects of dosage. No article reported phonological outcomes, three reported vocabulary, and eight reported morphosyntax. Dose frequency was the most common characteristic manipulated. Conclusions Research is in its infancy, and significant further research is required to inform speech-language pathologists in practice. Dosage characteristics are rarely adequately controlled for their individual effects to be identified. Findings to date suggest that there is a point in vocabulary and morphosyntax interventions after which there are diminishing returns from additional dosage. If dose is high (number of learning opportunities within a session), then the literature suggests that session frequency can be reduced. Frequent, short sessions (2/3 × per week, approximately 2 min) and less frequent, long sessions (1 × per week, approximately 20 min) have yielded the best outcomes when composite language measures have been used; however, replication and further research are required before clinicians can confidently integrate these findings into clinical practice.

Longitudinal Approach

AbstractIn order to better understand protective factors for internalizing problems, this longitudinal study examined positive emotions, emotion awareness and (non-)emotional communication skills in relation to somatic complaints and social anxiety in children with (N = 104) and without (N = 183) Developmental Language Disorder (DLD) using self-reported measures twice with a 9-month interval. Additionally, parents reported on their child’s communication problems and emotion communication at Time 1. Most importantly, since we found that increasing levels of emotion awareness related to decreases in social anxiety and somatic complaints in children with and without DLD, we conclude that children with DLD are likely to benefit from interventions aimed at improving their emotion awareness in addition to language interventions.

Purpose Developmental language disorder (DLD), defined by low language performance despite otherwise normal development, can negatively impact children's social and academic outcomes. This study is the 1st to examine DLD in Vietnamese. To lay the foundation, we identified cases of DLD in Vietnam and explored language-specific characteristics of the disorder. Method Teacher ratings of 1,250 kindergarteners living in Hanoi, Vietnam, were used to recruit children with and without risk for DLD. One hundred four children completed direct measures of vocabulary and language sampling, and their parents completed in-depth surveys. We examined convergence and divergence across tasks to identify measures that could serve as reliable indicators of risk. Then, we compared performance on direct language measures across ability levels. Results There were positive associations between teacher and parent report and between report and direct language measures. Three groups were identified based on convergence across measures: DLD, some risk for DLD, and no risk. The DLD group performed lowest on measures of receptive and expressive vocabulary, mean length of utterance, and grammaticality. Although children with DLD exhibited a greater number of errors, the types of errors found were similar across DLD and No Risk groups. Conclusions Similar to rates found globally, 7% of the kindergarten population in Vietnam exhibited risk for DLD. Results highlight the importance of parent and teacher report and the value of multiple measures to identify DLD. We discuss potential clinical markers for DLD in the Vietnamese language and outline future directions.

Purpose The goal was to determine whether interactive book reading outcomes for children with developmental language disorder (DLD) were affected by manipulation of dose (i.e., the number of exposures to the target word during a book reading session) and dose frequency (i.e., the number of repeated book reading sessions) and whether pretreatment factors predicted treatment response variation. Method Thirty-four kindergarten children with DLD (aged 5;0–6;2 [years;months]) were taught 1 set of words using the Dose 6 and Dose Frequency 6 format from a prior study ( Storkel, Voelmle, et al., 2017 ) and taught a different set of words using an alternative format, either Dose 4 × Dose Frequency 9 or Dose 9 × Dose Frequency 4, determined through random assignment. Word learning was tracked for each treatment via a definition task prior to, during, and after treatment. Results Results showed that children with DLD learned a significant number of words during treatment regardless of the dose and dose frequency format but that significant forgetting of newly learned words occurred in all formats once treatment was withdrawn. Individual differences in word learning were related to Clinical Evaluation of Language Fundamentals Core Language and Understanding Spoken Paragraphs scores. Conclusion When administered at an adequate intensity, variation in the dose and dose frequency of interactive book reading does not appear to influence word learning by children with DLD. Although interactive book reading continues to show promise as an effective word learning intervention for children with DLD, further development is needed to enhance the effectiveness of this treatment approach.

Verb Meaning

Purpose Verb learning is a critical but challenging part of language acquisition. Children with or at increased risk for developmental language disorder may particularly struggle with verb learning, and poor verb representations in turn may negatively impact children's language outcomes. Our goal is to examine literature on children's acquisition of verbs, identifying manipulable factors that may determine the ease or difficulty of acquiring a new verb meaning. Method In this narrative, nonsystematic review, we discuss findings about how verbs are learned and represented. Results Several aspects of the learning environment affect children's efforts to acquire verbs, including the linguistic context in which the verb is introduced, the timing of the linguistic label relative to the event it describes, the visual and linguistic variability, and the dose frequency. Conclusions We conclude that some learning situations are likely to be more helpful for children in the process of verb learning than others. We highlight some of the factors that contribute to good learning situations, and we discuss how these may differ depending on properties of the child and of the verb itself. Finally, we propose hypotheses for future translational and clinical research.

Tier 1

Children with Developmental Language Disorder (DLD) commonly present with oral language weaknesses which disrupt the development of literacy and impede related academic progress. While there is evidence to support the delivery of manualised Tier 2 interventions with this population, little is known about the effects of Tier 1 interventions. A retrospective cohort comparison was used to evaluate whether there was an observable effect of a manualised Tier 1 intervention compared to ‘business-as-usual’ on early literacy skills for children with DLD. Participants were 140 children attending a specialised education program with equivalent oral language skills and alphabetic knowledge at baseline. After 18 months formal literacy intervention, both groups were assessed on measures of early literacy skills. The differences between group means on all measures favoured the manualised intervention group, and they performed significantly better on a measure of nonword reading fluency. The findings indicate that a manualised Tier 1 intervention may be advantageous for children with DLD in developing proficiency in phonological recoding. This research contributes to the sparse evidence-base supporting the implementation of Tier 1 interventions for at risk populations, and findings warrant future research using experimental designs with tighter controls.

Dose Form

Purpose The aim of this study was to extract key learning from intervention studies in which qualitative aspects of dosage, dose form , have been examined for children with developmental language disorder (DLD)—in vocabulary, morphosyntax, and phonology domains. This research paper emerged from a pair of systematic reviews, aiming to synthesize available evidence regarding qualitative and quantitative aspects of dosage. While quantitative aspects had been experimentally manipulated, the available evidence for dose form (tasks or activities within which teaching episodes are delivered) was less definitive. Despite this, the review uncovered insights of value to DLD research. Method A preregistered systematic review (PROSPERO ID: CRD42017076663) adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was completed. Included papers were quasi-experimental, randomized controlled trial, or cohort analytic studies, published in any language between January 2006 and May 2019; oral language interventions with vocabulary, morphosyntax, or phonology outcomes; and participants with DLD ( M = 3–18 years). The intention was to include papers in which dose form was experimentally manipulated or statistically analyzed, while quantitative dosage aspects were controlled, such that definitive conclusions about optimal dose form could be drawn and gaps in the evidence identified. Results Two hundred and twenty-four papers met the above inclusion criteria; 27 focused on dose form . No study controlled for all quantitative aspects of dosage such that we could effectively address our original research questions. Despite this, key points of learning emerged with implications for future research. Conclusions There is tentative evidence of advantages for explicit over implicit instruction and of the benefits of variability in input, elicited production, and gestural and other visual supports. With careful design of dose form, there is potential to design more efficient interventions. Speech-language pathology research would benefit from an agreed taxonomy of dose form components and standardized reporting of intervention studies, to enable cross-study comparisons and a systematic accrual of knowledge to identify optimal dose form for clinical application.

Inferential Comprehension

Although children with developmental language disorder demonstrate poor inferential comprehension, few studies have evaluated the effect of interventions to improve inferencing. This study aimed to investigate the efficacy of a small-group intervention designed to improve oral inferential comprehension of narrative discourse. Thirty-seven 5- to 6-year-old children with developmental language disorder participated. The participants were randomly allocated to the oral inferential comprehension (IC) intervention or a control phonological awareness (PA) intervention. Small-group sessions took place twice a week over 8 weeks. Participants were assessed on narrative comprehension and phonological awareness skills pre- and post-intervention, and after a maintenance period of 8 weeks. Compared to the control PA group, the participants in the IC group demonstrated a significant increase in inferential comprehension scores from pre- to post-intervention, which was maintained over time. In addition, the IC group scored significantly higher than the PA group for inferential comprehension on a post-intervention generalization measure. There was no significant difference between the two groups for literal comprehension scores at any assessment point. The results demonstrate that the small-group intervention was effective at improving inferential comprehension of narratives in 5- to 6-year-old children with developmental language disorder. Additionally, generalized improvement was shown across the narrative context, and improvements were maintained two months following the intervention.

Purpose Relative lengths of the index (2D) and ring (4D) fingers in humans represent a retrospective biomarker of prenatal hormonal exposures. For this reason, the 2D:4D digit ratio can be used to investigate potential hormonal contributions to the etiology of neurodevelopmental disorders. This study tested potential group differences in 2D:4D digit ratios in a sample of boys with and without developmental language disorder (DLD) and examined the strength of associations between 2D:4D digit ratio and a battery of verbal and nonverbal measures. Method A group of 29 boys affected by DLD and a group of 76 boys with typical language abilities participated (age range = 5;6–11;0 years). Scanned images were used to measure finger lengths. Language measures included the core language subtests from the Clinical Evaluation of Language Fundamentals–Fourth Edition (Semel, Wiig, & Secord, 2003), a nonword repetition task, a sentence recall task, and the Test of Early Grammatical Impairment (Rice & Wexler, 2001). Results Significant group differences indicated lower 2D:4D digit ratios in the group with DLD. Modest associations were found between 2D:4D digit ratios and some Clinical Evaluation of Language Fundamentals–Fourth Edition subtests. Conclusions Prenatal hormone exposures may play a role in the etiology of some language symptoms.

The Developmental Language Disorder (DLD) is a delay in language skills that cannot be explained by sensory or cognitive difficulties. Currently, there are limited studies that analyze how socioeconomic, educational, and family variables influence reading skills of Spanish-speaking children with DLD at school. This study identifies how oral language performance and reading skills of children with DLD are linked to socioeconomic, educational, and family factors. Oral language, phonological awareness and reading abilities were assessed in a sample of 15 children diagnosed with DLD and their controls by age and gender. Children's parents answered a Likert scale questionnaire inquiring about some aspects related to the family's socioeconomic status, mothers' educational level, family support, academic average, and repetition of school years of the participants. The results indicate that children with DLD have a lower performance in phonological awareness tasks as well as in reading abilities. There is also a direct relationship between their performance in language and reading skills and variables as mother's educational level and family support. Likewise, children in the sample have a lower academic average as well as a higher school year repetition rate interfering in their academic life. Educational implications of these findings and a discussion on possible causality axes and protective factors that contributes to support this population are presented.

Purpose The aim of the current study was to investigate whether dual language experience modulates processing speed in typically developing (TD) children and in children with developmental language disorder (DLD). We also examined whether processing speed predicted vocabulary and sentence-level abilities in receptive and expressive modalities. Method We examined processing speed in monolingual and bilingual school-age children (ages 8–12 years) with and without DLD. TD children (35 monolinguals, 24 bilinguals) and children with DLD (17 monolinguals, 10 bilinguals) completed a visual choice reaction time task. The Clinical Evaluation of Language Fundamentals, the Peabody Picture Vocabulary Test, and the Expressive Vocabulary Test were used as language measures. Results The children with DLD exhibited slower response times relative to TD children. Response time was not modified by bilingual experience, neither in children with typical development nor children with DLD. Also, we found that faster processing speed was related to higher language abilities, but this relationship was not significant when socioeconomic status was controlled for. The magnitude of the association did not differ between the monolingual and bilingual groups across the language measures. Conclusions Slower processing speed is related to lower language abilities in children. Processing speed is minimally influenced by dual language experience, at least within this age range.
