Classification Accuracy of Teacher Ratings When Screening Nonmainstream English-Speaking Kindergartners for Language Impairment in the Rural South

Adversity Exposure, Syntax, and Specific Language Impairment: An Exploratory Study

PURPOSE

Children exposed to adversity (e.g., chronic poverty, traumatic events, and maltreatment) are at increased risk for performing below age expectations on norm-referenced language assessments, but it is unknown whether the risk is higher for specific language impairment (SLI). This exploratory study investigated whether adversity exposure is associated with reduced grammar knowledge and SLI.

METHOD

The syntax subtest of the Diagnostic Evaluation of Language Variation-Norm-Referenced (DELV-NR) assessment was administered to 30 school-age children with known histories of adversity exposure. Their primary caregiver also completed a comprehensive adversity exposure measure, which captured adverse event type, frequency, chronicity, and severity. Analyses included t tests, correlations, Mann-Whitney U tests, and chi-square.

RESULTS

Overall, the sample performed below age expectations on the DELV-NR Syntax subtest, and a higher percentage of participants (20%) met diagnostic criteria for SLI than expected. The SLI and typical language (TL) groups did not significantly differ in adversity dosage, frequency, chronicity, or severity; however, participants in the SLI group were 1.46 times more likely to have experienced physical trauma than the participants in the TL group.

CONCLUSIONS

Children with known histories of adversity exposure presented with grammatical deficits and SLI more often than expected based on the DELV-NR normative sample; however, features of the adverse event did not associate with SLI status except for exposure to physical trauma (e.g., physical abuse and victimization). Future research is needed to investigate the prevalence and potential causal pathways of SLI in this population.

Comparison of the Diagnostic Evaluation of Language Variation-Screening Test Risk Subtest to Two Other Screeners for Low-Income Prekindergartners Who Speak African American English and Live in the Urban South

Purpose We compared the Risk subtest of the Diagnostic Evaluation of Language Variation-Screening Test (DELV-Screening Test Risk) with two other screeners when administered to low-income prekindergartners (pre-K) who spoke African American English (AAE) in the urban South. Method Participants were 73 children (six with a communication disorder and 67 without) enrolled in Head Start or a publicly funded pre-K in an urban Southern city. All children completed the DELV-Screening Test Risk, the Fluharty Preschool Speech and Language Screening Test-Second Edition (FLUHARTY-2), and the Washington and Craig Language Screener (WCLS). Test order was counterbalanced across participants. Results DELV-Screening Test Risk error scores were higher than those reported for its standardization sample, and scores on the other screeners were lower than their respective standardization/testing samples. The 52% fail rate of the DELV-Screening Test Risk did not differ significantly from the 48% rate of the WCLS. Fail rates of the FLUHARTY-2 ranged from 34% to 75%, depending on the quotient considered and whether scoring was modified for dialect. Although items and subtests assumed to measure similar constructs were correlated to each other, the three screeners led to inconsistent pass/fail outcomes for 44% of the children. Conclusions Like other screeners, the DELV-Screening Test Risk subtest may lead to high fail rates for low-income pre-K children who speak AAE in the urban South. Inconsistent outcomes across screeners underscore the critical need for more study and development of screeners within the field.

Turn the Page, Speech-Language Pathologists: Adequate, Authentic, and Accurate Representation as a Consideration in the Selection of Picture Books for Use in Treatment

Purpose This tutorial discusses what it means to be a culturally responsive speech-language pathologist (SLP) and then grounds this discussion in strategies that SLPs can engage in to diversify the books and other materials that they use in clinical practice. Method We motivate the tutorial by reviewing policy statements and theoretical information from allied literature. Then, we suggest some ways that SLPs can reflect on their practice to enact an antiracist/culturally responsive approach to treatment, taking the selection of children's literature up as a particular example. We identified strategies that have been suggested across a variety of fields and illustrate these strategies with examples. We both provide recommendations for how to select picture books and also suggest ways to implement these suggestions with accountability. Conclusions There is a need for SLPs to reflect on how to be culturally responsive in their practice and to review their materials selection practices with regard to how materials reflect the composition of their caseloads. As a predominantly White profession serving diverse caseloads, we have an ethical obligation to review our choice of materials and align them with culturally responsive practices.

Teacher Report of Students' Dialect Use and Language Ability

Purpose For many school-age children, teachers are the first professionals to refer for speech/language services. However, many speech-language pathologists note that students without language disorders who speak non-mainstream American English (NMAE) dialects are referred to speech/language evaluation. This research note presents results of a preliminary study exploring teachers' ability to report student dialect use and how teacher reports of language ability depend on their perception of the student's dialect use. Method Teachers completed a brief two-question survey about students' dialect use and a standardized questionnaire about students' language and literacy skills for 254 students (K‑second grades). A subset of 30 students completed a standardized screener of dialect use and language ability. Results Teachers reported that 12.2% of students spoke an NMAE dialect, whereas 77.2% did not. In sharp contrast, the Diagnostic Evaluation of Language Variation-Screening Test indicated that 63% of students spoke an NMAE dialect, and 37% spoke MAE, suggesting a discrepancy between teachers' perceptions of dialect use and children's dialect use. Written responses suggested teachers may confuse NMAE dialect use and bilingualism or speech/language difficulties. Interestingly, teachers reported lower language skills among students they believe speak an NMAE dialect (p = .021). Conclusions These results provide preliminary evidence that teachers may have difficulty determining student dialect use and may report lower language skills for students they believe speak an NMAE dialect. Interprofessional collaborations between teachers and speech-language pathologists may be able to reduce the likelihood of misdiagnosis of language disorders among students who speak NMAE dialects.

Survey of assessment and intervention practices for students who speak African American English

Speech-Language Pathologists (SLPs) working with students from culturally and linguistically diverse backgrounds are encouraged to be "familiar with nondiscriminatory testing and dynamic assessment procedures" (ASHA, 2003). Little is known, however, about the extent to which SLPs implement these methods into their clinical practice. The current study explores the assessment and intervention practices used by SLPs in two states in the US for students who speak African American English (AAE), including the types and frequency of clinical practices. 247 SLPs completed an online survey regarding clinical practices for students who speak AAE as well as a questionnaire regarding their knowledge of the linguistic features of AAE. Half of SLPs reported using modified or alternative assessment practices the majority of the time or some of the time for students who speak AAE; however, SLPs reported using modified or alternative treatment practices less often. Modified scoring of standardized assessments and selecting different intervention strategies were the most commonly reported clinical practices. Knowledge of linguistic features of AAE was a significant predictor of the frequency with which SLPs report implementing modified or alternative assessment and intervention practices and SLPs with the highest levels of knowledge of AAE utilize different clinical practices than those with lower levels of knowledge of AAE. Additional information is needed about the most effective clinical practices for students who speak AAE and the barriers SLPs face to implementing nondiscriminatory clinical practices.

Specific Language Impairment in African American English and Southern White English: Measures of Tense and Agreement With Dialect-Informed Probes and Strategic Scoring

Purpose In African American English and Southern White English, we examined whether children with specific language impairment (SLI) overtly mark tense and agreement structures at lower percentages than typically developing (TD) controls, while also examining the effects of dialect, structure, and scoring approach. Method One hundred six kindergartners completed 4 dialect-informed probes targeting 8 tense and agreement structures. The 3 scoring approaches varied in the treatment of nonmainstream English forms and responses coded as Other (i.e., those not obligating the target structure). The unmodified approach counted as correct only mainstream overt forms out of all responses, the modified approach counted as correct all mainstream and nonmainstream overt forms and zero forms out of all responses, and the strategic approach counted as correct all mainstream and nonmainstream overt forms out of all responses except those coded as Other. Results With the probes combined and separated, the unmodified and strategic scoring approaches showed lower percentages of overt marking by the SLI groups than by the TD groups; this was not always the case for the modified scoring approach. With strategic scoring and dialect-specific cut scores, classification accuracy (SLI vs. TD) was highest for the 8 individual structures considered together, the past tense probe, and the past tense probe irregular items. Dialect and structure effects and dialect differences in classification accuracy also existed. Conclusions African American English- and Southern White English-speaking kindergartners with SLI overtly mark tense and agreement at lower percentages than same dialect-speaking TD controls. Strategic scoring of dialect-informed probes targeting tense and agreement should be pursued in research and clinical practice.

Perspectivas e práticas de apoio educativo aos alunos com transtornos da linguagem em Portugal

RESUMO Objetivo Contribuir para o conhecimento das perspectivas e práticas de apoio educativo aos alunos com transtornos da linguagem em contextos inclusivos em Portugal. Método Após revisão da bibliografia sobre o tema, foi elaborado um questionário, posteriormente aplicado a 123 professores do ensino regular. Para a análise dos dados recolhidos, foi realizada uma análise estatística descritiva e inferencial das variáveis dependentes, utilizando testes paramétricos. Resultados A análise descritiva revela que a maioria dos professores conhece o conceito de transtornos da linguagem e considera importante compreender o desenvolvimento da linguagem ao lidar com alunos com essa problemática. No entanto, mais da metade dos inquiridos acha que não possui formação nem informações suficientes acerca da aquisição e do desenvolvimento da linguagem e também não concorda que possua competências suficientes para contribuir para a identificação de alunos com transtornos da linguagem. Os resultados relativos à análise inferencial revelam diferenças estatisticamente significativas no que diz respeito ao gênero, ao tempo de serviço e ao distrito. Os resultados obtidos demonstram boas qualidades métricas no que se refere à consistência interna. Conclusão Os resultados evidenciam a necessidade de formação e informação dos professores acerca da aquisição e do desenvolvimento da linguagem e, mais especificamente, dos transtornos da linguagem. Demonstram também que os professores do ensino regular poder-se-ão deparar com dificuldades no apoio educativo aos alunos com transtornos da linguagem e, particularmente, em delinear estratégias adequadas às suas necessidades, nomeadamente na elaboração de programas educativos individualizados.

Prologue: Toward Accurate Identification of Developmental Language Disorder Within Linguistically Diverse Schools

Purpose

Although the 5 studies presented within this clinical forum include children who differ widely in locality, language learning profile, and age, all were motivated by a desire to improve the accuracy at which developmental language disorder is identified within linguistically diverse schools. The purpose of this prologue is to introduce the readers to a conceptual framework that unites the studies while also highlighting the approaches and methods each research team is pursuing to improve assessment outcomes within their respective linguistically diverse community.

Method

A disorder within diversity framework is presented to replace previous difference vs. disorder approaches. Then, the 5 studies within the forum are reviewed by clinical question, type of tool(s), and analytical approach.

Conclusion

Across studies of different linguistically diverse groups, research teams are seeking answers to similar questions about child language screening and diagnostic practices, using similar analytical approaches to answer their questions, and finding promising results with tools focused on morphosyntax. More studies that are modeled after or designed to extend those in this forum are needed to improve the accuracy at which developmental language disorder is identified.
