Assessment And Diagnosis

Background For many years research and practice have noted the impact of the heterogeneous nature of Developmental Language Disorder (also known as language impairment or specific language impairment) on diagnosis and assessment. Recent research suggests the disorder is not restricted to the language domain and against this background, the challenge for the practitioner is to provide accurate assessment and effective therapy. The speech and language therapist aims to support the child and their carers to achieve the best outcomes. However, little is known about the experiences of the speech and language therapist in the assessment process, in contrast to other childhood disorders, yet their expertise is central in the assessment and diagnosis of children with language disorder. Aims This study aimed to gain an in-depth understanding of the experiences of speech and language therapists involved in the assessment and diagnosis of children with Developmental Language Disorder including the linguistic and non-linguistic aspects of the disorder. Methods and procedures The qualitative study included three focus groups to provide a credible and rich description of the experiences of speech and language therapists involved in the assessment of Developmental Language Disorder. The speech and language therapists who participated in the study were recruited from different types of institution in three NHS trusts across the UK and all were directly involved in the assessment and diagnosis procedures. The lengths of speech and language therapist experience ranged from 2 years to 38 years. The data were analysed using inductive thematic analysis within a phenomenological approach. Outcomes and results The analysis of the data showed three main themes relating to the speech and language therapists’ experience in assessment and diagnosis of Developmental Language Disorder. These themes were the participants’ experiences of the barriers to early referral (subthemes – parents’ misunderstanding and misconceptions of Developmental Language Disorder, bilingualism can mask Developmental Language Disorder and public lack of knowledge of support services), factors in assessment (subthemes – individual nature of impairments, choosing appropriate assessments, key indicators and identifying non-language difficulties) and the concerns over continued future support (subthemes – disadvantages with academic curriculum, disadvantages for employment, impact of Developmental Language Disorder on general life chances). Conclusions and implications This study provides first-hand evidence from speech and language therapists in the assessment of children with Developmental Language Disorder, drawing together experiences from speech and language therapists from different regions. The implications are that support for early referral and improved assessment tools are needed together with greater public awareness of Developmental Language Disorder. The implications are discussed in relation to the provision of early and effective assessment and the use of current research in these procedures.

The Impact

Purpose Many children with developmental language disorder (DLD) have weaknesses in executive functioning (EF), specifically in tasks testing interference control and working memory. It is unknown how EF develops in children with DLD, if EF abilities are related to DLD severity and persistence, and if EF weaknesses expand to selective attention. This study aimed to address these gaps. Method Data from 78 children with DLD and 39 typically developing (TD) children were collected at three times with 1-year intervals. At Time 1, the children were 5 or 6 years old. Flanker, Dot Matrix, and Sky Search tasks tested interference control, visuospatial working memory, and selective attention, respectively. DLD severity was based on children's language ability. DLD persistence was based on stability of the DLD diagnosis. Results Performance on all tasks improved in both groups. TD children outperformed children with DLD on interference control. No differences were found for visuospatial working memory and selective attention. An interference control gap between the DLD and TD groups emerged between Time 1 and Time 2. Severity and persistence of DLD were related to interference control and working memory; the impact on working memory was stronger. Selective attention was unrelated to DLD severity and persistence. Conclusions Age and DLD severity and persistence determine whether or not children with DLD show EF weaknesses. Interference control is most clearly impaired in children with DLD who are 6 years and older. Visuospatial working memory is impaired in children with severe and persistent DLD. Selective attention is spared.

Purpose The purpose of this article is to situate the recent language disorder label debate within a school's perspective. As described in two recent The ASHA Leader articles, there is international momentum to change specific language impairment to developmental language disorder . Proponents of this change cite increased public awareness and research funding as part of the rationale. However, it is unclear whether this label debate is worthwhile or even practical for the school-based speech-language pathologist (SLP). A discussion of the benefits and challenges to a shift in language disorder labels is provided. Conclusions Although there are important arguments for consistency in labeling childhood language disorder, the reality of a label change in U.S. schools is hard to imagine. School-based services are driven by eligibility through the Individuals with Disabilities Education Act, which has its own set of labels. There are myriad reasons why advocating for the developmental language disorder label may not be the best use of SLPs' time, perhaps the most important of which is that school SLPs have other urgent priorities.

Purpose The current “specific language impairment” and “developmental language disorder” discussion might lead to important changes in how we refer to children with language disorders of unknown origin. The field has seen other changes in terminology. This article reviews many of these changes. Method A literature review of previous clinical labels was conducted, and possible reasons for the changes in labels were identified. Results References to children with significant yet unexplained deficits in language ability have been part of the scientific literature since, at least, the early 1800s. Terms have changed from those with a neurological emphasis to those that do not imply a cause for the language disorder. Diagnostic criteria have become more explicit but have become, at certain points, too narrow to represent the wider range of children with language disorders of unknown origin. Conclusions The field was not well served by the many changes in terminology that have transpired in the past. A new label at this point must be accompanied by strong efforts to recruit its adoption by clinical speech-language pathologists and the general public.

Developmental Conditions

Language and communication deficits characterize both autism spectrum disorder and developmental language disorder, and the possibility of there being a common profile of these is a matter of tireless debate in the research community. This experimental study addresses the relation of these two developmental conditions in the critical topic of language. Α total of 103 children (79 males, 24 females) participated in the present study. Specifically, the study’s sample consisted of 40 children with autism, 28 children with developmental language disorder, and 35 typically developing children between 6 and 12 years old. All children completed language and cognitive measures. The results showed that there is a subgroup inside the autism group of children who demonstrate language difficulties similar to children with developmental language disorder. Specifically, two different subgroups were derived from the autism group; those with language impairment and those without. Both autism and language-impaired groups scored lower than typically developing children on all language measures indicating a common pathology in language ability. The results of this study shed light on the relation between the two disorders, supporting the assumption of a subgroup with language impairment inside the autism spectrum disorder population. The common picture presented by the two developmental conditions highlights the need for further research in the field.

Insight Into

This chapter provides an overview of the evidence on grammatical number processing taken from cognitive neuropsychology, including developmental delays and impairments of language (e.g. developmental language disorder, and Williams syndrome) and aphasia, an acquired language impairment after brain injury. These types of language impairment can give insight into the functional architecture of nominal number processing by looking at error patterns that arise in each of the aforementioned populations. By classifying observed responses in language production tasks into non-number and number errors, we are able to reveal underlying mechanisms of syntactic rules and their representations when they develop, but also learn about processes and representation of number when this information breaks down.

Evaluation And Assessment

Purpose Though we live in a digital era, libraries offer significant hours of in-person reference services, in combination with online reference services. Nevertheless, an increase in requests for in-person, individualized research consultations (IRCs) over the last few years has been observed. IRCs between librarians and students are common practice in academic institutions. While these sessions can be deemed useful for patrons, as they are tailored to their specific needs, however, they can also be time consuming for the librarians. Therefore, it is important to evaluate this service, and assess its impact in order to ensure that the users are getting the most out of their sessions. The purpose of this paper is to gather information on the evaluation and assessment tools that Canadian institutions are using to obtain feedback, measure their impact and improve their consultation services. Design/methodology/approach A bilingual (French and English) web-based questionnaire was issued, with a generic definition of IRCs provided. The questionnaire included general demographics and background information on IRC practices among Canadian academic librarians, followed by reflective questions on the assessment process of such practices. The questionnaire was sent to Canadian academic librarians via e-mail, using professional librarian associations’ listservs, and Twitter was used for dissemination as well. Findings Major findings of the survey concluded that the disciplines of health sciences and medicine, as well as the arts and humanities are the heaviest users of the IRC service model. On average, these sessions are one hour in length, provided by librarians who often require advanced preparation time to adequately help the user, with infrequent follow-up appointments. It was not surprising that a lack of assessment methods for IRCs was identified among Canadian academic libraries. Most libraries have either no assessment in place for IRCs, or they rely heavily on informal feedback from users, comments from faculty members and so on. A small portion of libraries use usage statistics to assess their IRCs service, but other means of assessment are practically non-existent. Research limitations/implications The survey conducted was only distributed to Canadian academic libraries. Institutions across the USA and other countries that also perform IRCs may have methods for evaluating and assessing these sessions which the authors did not gather; therefore, the evidence is biased. As well, each discipline approaches IRCs very differently; therefore, it is challenging to compare the evaluation and assessment methods between each discipline. Furthermore, the study’s population is unknown, as the authors did not know the exact number of librarians or library staff providing IRCs by appointment in academic Canadian institution. While the response rate was reasonably good, it is impossible to know if the sample is representative of the population. Also, it needs to be acknowledged that the study is exploratory in nature as this is the first study solely dedicated at examining academic librarians’ IRC practices. Further research is needed. As future research is needed to evaluate and assess IRCs with an evidence-based approach, the authors will be conducting a pre-test and post-test to assess the impact of IRC on students’ search techniques. Originality/value Evidence-based practice for IRCs is limited. Very few studies have been conducted examining the evaluation and assessment methods of these sessions; therefore, it was believed that a “lay of the land,” so to speak, was needed. The study is exploratory in nature, as this is the first study solely dedicated at examining the evaluation and assessment methods of academic librarians’ IRC practices.

Repetition Task

Purpose: Research on the typical and impaired grammatical acquisition of Arabic is limited. This study systematically examined the morphosyntactic abilities of Arabic-speaking children with and without developmental language disorder (DLD) using a novel sentence repetition task. The usefulness of the task as an indicator of DLD in Arabic was determined. Method: A LITMUS (Language Impairment Testing in Multilingual Settings) sentence repetition task was developed in Palestinian Arabic (LITMUS-SR-PA-72) and administered to 30 children with DLD ( M = 61.50 months, SD = 11.27) and 60 age-matched typically developing (TD) children ( M = 63.85 months, SD = 10.16). The task targeted grammatical structures known to be problematic for Arabic-speaking children with DLD (language specific) and children with DLD across languages (language independent). Responses were scored using binary, error, and structural scoring methods. Results: Children with DLD scored below TD children on the LITMUS-SR-PA-72, in general, and in the repetition of language-specific and language-independent structures. The frequency of morphosyntactic errors was higher in the DLD group relative to the TD group. Despite the large similarity of the type of morphosyntactic errors between the two groups, some atypical errors were exclusively produced by the DLD group. The three scoring methods showed good diagnostic power in the discrimination between children with DLD and children without DLD. Conclusions: Sentence repetition was an area of difficulty for Palestinian Arabic–speaking children with DLD. The DLD group demonstrated difficulties with language-specific and language-independent structures, particularly complex sentences with noncanonical word order. Most grammatical errors made by the DLD group resembled those of the TD group and were mostly omissions or substitutions of grammatical affixes or omissions of function words. SR appears to hold promise as a good indicator for the presence or absence of DLD in Arabic. Further validation of these findings using population-based studies is warranted.

Purpose We examined the English semantic performance of three hundred twenty-seven 7- to 10-year-old Spanish–English bilinguals with ( n = 66) and without ( n = 261) developmental language disorder (DLD) with varying levels of English experience to classify groups. Method English semantic performance on the Bilingual English–Spanish Assessment—Middle Extension Experimental Test Version (Peña et al., 2008) was evaluated by language experience, language ability, and task type. Items that best identified DLD for children with balanced and high English experience were selected. Separately, items that best identified children with high Spanish experience were selected. Results Typically developing bilingual children performed significantly higher than their peers with DLD across semantic tasks, with differences associated with task type. Classification accuracy was fair when item selection corresponded to balanced or high level of experience in English, but poor for children with high Spanish experience. Selecting items specifically for children with high Spanish experience improved classification accuracy. Conclusions Tailoring semantic items based on children's experience is a promising direction toward organizing items on a continuum of exposure. Here, classification effectively ruled in impairment. Future work to refine semantic items that more accurately represent the continuum of exposure may help rule out language impairment.

Purpose The CATALISE group (Bishop, Snowling, Thompson, Greenhalgh, & CATALISE Consortium, 2016; Bishop, Snowling, Thompson, Greenhalgh, & CATALISE-2 Consortium, 2017) recommended that the term developmental language disorder (DLD) be used to refer to neurodevelopmental language deficit. In this tutorial, we explain the appropriate application of the term and present advantages in adhering to the CATALISE recommendations. Conclusion Both specific language impairment and DLD refer to a neurodevelopmental condition that impairs spoken language, is long-standing and, is not associated with any known causal condition. The applications of the terms specific language impairment and DLD differ in breadth and the extent to which identification depends upon functional impact. Use of the term DLD would link advocacy efforts in the United States to those in other English-speaking countries. The criteria for identifying DLD presented in the CATALISE consensus offer opportunities for scientific progress while aligning well with practice in U.S. public schools.

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.
