The Russian Aphasia Test: The first comprehensive, quantitative, standardized, and computerized aphasia language battery in Russian.

The lack of standardized language assessment tools in Russian impedes clinical work, evidence-based practice, and research in Russian-speaking clinical populations. To address this gap in assessment of neurogenic language disorders, we developed and standardized a new comprehensive assessment instrument-the Russian Aphasia Test (RAT). The principal novelty of the RAT is that each subtest corresponds to a specific level of linguistic processing (phonological, lexical-semantic, syntactic, and discourse) in different domains: auditory comprehension, repetition, and oral production. In designing the test, we took into consideration various (psycho)linguistic factors known to influence language performance, as well as specific properties of Russian. The current paper describes the development of the RAT and reports its psychometric properties. A tablet-based version of the RAT was administered to 85 patients with different types and severity of aphasia and to 106 age-matched neurologically healthy controls. We established cutoff values for each subtest indicating deficit in a given task and cutoff values for aphasia based on the Receiver Operating Characteristic curve analysis of the composite score. The RAT showed very high sensitivity (> .93) and specificity (> .96), substantiating its validity for determining presence of aphasia. The test's high construct validity was evidenced by strong correlations between subtests measuring similar linguistic processes. The concurrent validity of the test was also strong as demonstrated by a high correlation with an existing aphasia battery. Overall high internal, inter-rater, and test-retest reliability were obtained. The RAT is the first comprehensive aphasia language battery in Russian with properly established psychometric properties. It is sensitive to a wide range of language deficits in aphasia and can reliably characterize individual profiles of language impairments. Notably, the RAT is the first comprehensive aphasia test in any language to be fully automatized for administration on a tablet, maximizing further standardization of presentation and scoring procedures.

Analysis of English free association network reveals mechanisms of efficient solution of Remote Association Tests.

We study correlations between the structure and properties of a free association network of the English language, and solutions of psycholinguistic Remote Association Tests (RATs). We show that average hardness of individual RATs is largely determined by relative positions of test words (stimuli and response) on the free association network. We argue that the solution of RATs can be interpreted as a first passage search problem on a network whose vertices are words and links are associations between words. We propose different heuristic search algorithms and demonstrate that in "easily-solving" RATs (those that are solved in 15 seconds by more than 64% subjects) the solution is governed by "strong" network links (i.e. strong associations) directly connecting stimuli and response, and thus the efficient strategy consist in activating such strong links. In turn, the most efficient mechanism of solving medium and hard RATs consists of preferentially following sequence of "moderately weak" associations.

Assessing language development in Arabic: The Arabic language: Evaluation of function (ALEF).

Arabic is characterized by extensive dialectal variation, diglossia, and substantial morphological complexity. Arabic lacks comprehensive diagnostic tools that would allow for a systematic evaluation of its development, critical for the early identification of language difficulties in the spoken and written domains. To address this gap, we have developed an assessment battery called Arabic Language: Evaluation of Function (ALEF), aimed at children aged 3 to 11 years. ALEF consists of 17 subtests indexing different language domains, modalities, and associated skills and representational systems. We administered the ALEF battery to native Gulf Arabic-speaking children (n = 467; ages 2.5 to 10.92; 55% boys; 20 children in each 6-month age band) in Saudi Arabia in two data collection waves. Analyses examining the psychometric properties of the instrument indicated that after the removal of misfitting items, the ALEF subtests had reliability coefficients in the range from 0.78 to 0.98, and resulting subtest scores displayed a consistent profile of positive intercorrelations and age effects. Taken together, the results indicate that the ALEF battery has good psychometric properties, and can be used for the purpose of evaluating early language development in Gulf Arabic speaking children, pending further refinement of the test structure, examination of gender-related differential item functioning, and norming.

Norm-Referenced Language Test Selection Practices for Elementary School Children With Suspected Developmental Language Disorder.

Purpose Standardized norm-referenced tests are an important aspect of language assessment for school-age children. This study explored the language test selection practices of school-based speech-language pathologists (SLPs) working with elementary school children suspected of having developmental language disorder. Specifically, we investigated which tests were most commonly selected as clinicians' first-choice and follow-up tests, which factors impacted their test selection decisions, and what sources of information they used to determine the psychometric quality of tests. Method School-based SLPs completed a web-based questionnaire regarding their use of norm-referenced language tests. A total of 370 elementary school SLPs completed the questionnaire. Results The vast majority of participants indicated that omnibus language tests are their first choice of test. For follow-up tests, participants selected semantics tests, especially single-word vocabulary tests, significantly more often than tests of pragmatics, processing skills, and morphology/syntax. Participants identified multiple factors as affecting test selection, including availability, familiarity, psychometric features, and others. Although more SLPs reported using data-based than subjective sources of information to judge the psychometric quality of tests, a substantial proportion reported that they relied on subjective sources. Conclusions Clinicians have a strong preference for using omnibus language tests. Follow-up test selection does not appear to align with the language difficulties most associated with developmental language disorder. The substantial use of subjective information about psychometric qualities of tests suggests that many SLPs may not attend to the technical meanings of terms such as validity, reliability, and diagnostic accuracy. These results indicate a need for improvement in evidence-based language assessment practices. Supplemental Material https://doi.org/10.23641/asha.13022471.

Development and evaluation of the Ingwavuma receptive vocabulary test: A tool for assessing receptive vocabulary in isiZulu-speaking preschool children.

BACKGROUND: This study used local resources- community members, photographer and speech therapists to develop a new test for screening receptive language skills and sought to determine its feasibility for use with a larger population in KwaZulu-Natal province, South Africa. OBJECTIVES: The aim of this study was to develop a one-word receptive vocabulary test appropriate for screening and diagnosis of isiZulu-speaking preschool-aged children. The objectives were (1) to determine sensitivity and specificity of the Ingwavuma Receptive Vocabulary Test (IRVT) and (2) to determine the relationship of IRVT scores with age, gender, time and the confounding variables of stunting and school. METHOD: The study was quantitative, cross-sectional and descriptive in nature. The IRVT was piloted before being administered to 51 children (4-6 years old). Statistical analysis of test item prevalence, correlations to confounding variables and validity measurements were conducted using Statistical Package for Social Scientists version 25 (SPSS 25). RESULTS: The IRVT was able to profile the receptive skills for the preschool children in Ingwavuma. The mean raw score for boys was 35, and 32 for girls. There was a significant Pearson correlation between test scores and age (0.028, p 0.05) with a high effect size (Cohen's d = 0. 949), gender (r = -0.032, p 0.05) with a medium effect size (Cohen's d = 0.521) and school (r = 0.033, p 0.05) with a small effect size (Cohen's d = 0.353). The sensitivity and specificity values were 66.7% and 33%, respectively. The test reliability (Cronbach's alpha) was 0.739, with a good test-retest reliability. CONCLUSION: The IRVT has potential as a screening test for isiZulu receptive vocabulary skills amongst preschool children. This study contributes to a development of clinical and research resources for assessing language abilities.

Taking Language Samples Home: Feasibility, Reliability, and Validity of Child Language Samples Conducted Remotely With Video Chat Versus In-Person.

Purpose There has been increased interest in using telepractice for involving more diverse children in research and clinical services, as well as when in-person assessment is challenging, such as during COVID-19. Little is known, however, about the feasibility, reliability, and validity of language samples when conducted via telepractice. Method Child language samples from parent-child play were recorded either in person in the laboratory or via video chat at home, using parents' preferred commercially available software on their own device. Samples were transcribed and analyzed using Systematic Analysis of Language Transcripts software. Analyses compared measures between-subjects for 46 dyads who completed video chat language samples versus 16 who completed in-person samples; within-subjects analyses were conducted for a subset of 13 dyads who completed both types. Groups did not differ significantly on child age, sex, or socioeconomic status. Results The number of usable samples and percent of utterances with intelligible audio signal did not differ significantly for in-person versus video chat language samples. Child speech and language characteristics (including mean length of utterance, type-token ratio, number of different words, grammatical errors/omissions, and child speech intelligibility) did not differ significantly between in-person and video chat methods. This was the case for between-group analyses and within-child comparisons. Furthermore, transcription reliability (conducted on a subset of samples) was high and did not differ between in-person and video chat methods. Conclusions This study demonstrates that child language samples collected via video chat are largely comparable to in-person samples in terms of key speech and language measures. Best practices for maximizing data quality for using video chat language samples are provided.

A Sentence Repetition Task for Early Language Assessment in Spanish.

Sentence repetition tasks have been widely used in the last years as a diagnostic tool in developmental language disorders. However in Spanish there are few (if any) of these instruments, especially for younger children. In this context, we develop a new Sentence Repetition Task for assessing language (morphosyntactic) abilities of very young Spanish children. A list of 33 sentences of different length and complexity was created and included in the task. A total of 130 typical developing children from 2 to 4 years of age were engaged in a play situation and asked to repeat the sentences. Children's answers were scored for accuracy at sentence and word level and error analysis at the word level was undertaken. Besides a subsample of 92 children completed a non-word repetition task. First results show its adequacy to children from 2 to 4 years of age, its capacity to discriminate between different developmental levels, and its concurrent validity with the nonword repetition task.

Contextual influences on sentence repetition as a tool for the identification of language impairment in Grade 3 Sepedi-English bilinguals: A case against bilingual norms.

BACKGROUND: Specific language impairment (SLI) is difficult to identify because it is a subtle linguistic difficulty, and there are a few measures available to differentiate between typical and atypical language development in bilinguals. Sentence repetition (SR) has strong theoretical foundations and research evidence as a valid tool for the identification of SLI in bilinguals. OBJECTIVE: This study assessed the value of SR using peer group comparisons to identify Sepedi-English bilingual children at the risk of SLI. METHOD: One hundred and two Grade 3 learners in three different contexts of education were assessed on equivalent English and Sepedi SR measures. RESULTS: Eleven participants who scored between 1 and 2 standard deviations (SD) below the peer group means on both the English and Sepedi SR tests were identified with possible SLI. Learners in the English language of learning and teaching (LoLT) - Sepedi additional language (SAL) context obtained similar scores in both languages, a higher score in English than the English LoLT group and a higher score in Sepedi than the Sepedi LoLT - EAL group. The English LoLT group obtained a significantly higher score in English than in Sepedi and a significantly lower score than the other two groups in Sepedi. The Sepedi LoLT group obtained a significantly higher score in Sepedi than in English, their additional language, in which they obtained a significantly lower score than the other two groups. CONCLUSION: Sentence repetition tasks are valid screening tools to identify bilingual children with SLI by comparing them to peer groups. The SR tests were sensitive to language practices in different educational contexts. It was observed that a bilingual approach that uses both English and the home language as academic languages leads to better language outcomes.

Predicting Response to Vocabulary Intervention Using Dynamic Assessment.

Purpose The purpose of this study was to examine how well students' response to a morphological vocabulary intervention can be predicted before the start of the intervention from traditional static assessments and to determine whether a dynamic assessment with graduated prompts improves the prediction. Method A planned secondary analysis of a randomized trial of a morphological vocabulary intervention for fifth-grade students with limited vocabulary was conducted. Response to this intervention was examined for 111 participants based on their development in definitions of morphologically transparent words from pretest to posttest. Traditional static measures of vocabulary, knowledge of morphology, and morphological analysis as well as a dynamic assessment of morphological analysis were evaluated as predictors of students' response to intervention. Results The static pretest measures predicted more than half of the overall variance in students' response to intervention and provided a good classification of students with subsequent poor or good response to intervention. The single best static predictor was the static assessment of morphological analysis. Furthermore, the dynamic assessment added significantly to the prediction of the overall variance in students' response to intervention and to the correct early classification of students as poor or good responders. Conclusions The results suggest that an acceptable level of prediction of students' response to morphological vocabulary intervention can be obtained by means of a couple of static morphological measures. This study also provides evidence for the added predictive value of a dynamic assessment of morphological analysis.

Development and application of a Chinese Version of the Language Screening Test (CLAST) in post-stroke patients.

Aphasia shows high incidence in stroke patients and seriously impairs language comprehension, verbal communication, and social activities. Therefore, screening aphasic patients during the acute phase of stroke is crucial for language recovery and rehabilitation. The present study developed a Chinese version of the Language Screening Test (CLAST) and validated it in post-stroke patients.The CLAST was adapted from the Language Screening Test developed by Constance et al to incorporate Chinese cultural and linguistic specificities, and administered to 207 acute stroke patients and 89 stabilized aphasic or non-aphasic patients. Based on the Western Aphasia Battery (WAB) test, its reliability and validity were assessed. A cut-off for the CLAST in Chinese patients was determined by ROC curve analysis.The CLAST comprised 5 subtests and 15 items, including 2 subscores, namely expression (8 points, assessing naming, repetition, and automatic speech) and receptive (7 points maximum, evaluating picture recognition, and verbal instructions) indexes. Analysis of the alternate-form reliability of the questionnaire showed a retest correlation coefficient of 0.945 (P < .001). Intraclass correlation coefficients of three rating teams were >0.98 (P < .001). Internal consistency analysis showed a Cronbach's alpha coefficient of 0.909 (P < .001). The non-aphasia group showed higher scores than the aphasia group (14.2 ±â€Š1.3 vs 10.6 ±â€Š3.8) (P < .01). The questionnaire showed good construct validity by factor analysis. ROC curve analysis showed high sensitivity and specificity for the CLAST, with a cut-off of 13.5.The CLAST is suitable for Chinese post-stroke patients during the acute phase, with high reliability, validity, sensitivity, and specificity.

Cross-validation of non-memory-based embedded performance validity tests for detecting invalid performance among patients with and without neurocognitive impairment.

INTRODUCTION: Embedded performance validity tests (PVTs) allow for continuous and economical validity assessment during neuropsychological evaluations; however, similar to their freestanding counterparts, a limitation of well-validated embedded PVTs is that the majority are memory-based. This study cross-validated several previously identified non-memory-based PVTs derived from language, processing speed, and executive functioning tests within a single mixed clinical neuropsychiatric sample with and without cognitive impairment. METHOD: This cross-sectional study included data from 124 clinical patients who underwent outpatient neuropsychological evaluation. Validity groups were determined by four independent criterion PVTs (failing ≤1 or ≥2), resulting in 98 valid (68% cognitively impaired) and 26 invalid performances. In total, 23 previously identified embedded PVTs derived from Verbal Fluency (VF), Trail Making Test (TMT), Stroop (SCWT), and Wisconsin Card Sorting Test (WCST) were examined. RESULTS: All VF, SCWT, and TMT PVTs, along with WCST Categories, significantly differed between validity groups (ηp2 =.05-.22) with areas under the curve (AUCs) of.65-.81 and 19-54% sensitivity (≥89% specificity) at optimal cut-scores. When subdivided by impairment status, all PVTs except for WCST Failures to Maintain Set were significant (AUCs =.75-94) with 33-85% sensitivity (≥90% specificity) in the cognitively unimpaired group. Among the cognitively impaired group, most VF, TMT, and SCWT PVTs remained significant, albeit with decreased accuracy (AUCs =.65-.76) and sensitivities (19-54%) at optimal cut-scores, whereas all WCST PVTs were nonsignificant. Across groups, SCWT embedded PVTs evidenced the strongest psychometric properties. CONCLUSION: VF, TMT, and SCWT embedded PVTs generally demonstrated moderate accuracy for identifying invalid neuropsychological performance. However, performance on these non-memory-based PVTs from processing speed and executive functioning tests are not immune to the effects of cognitive impairment, such that alternate cut-scores (with reduced sensitivity if adequate specificity is maintained) are indicated in cases where the clinical history is consistent with cognitive impairment. In contrast, WCST indices generally had poor accuracy.

Evaluating the Scope of Language Impairments in a Patient with Triple X Syndrome: A Brief Report.

The phenotype of triple X syndrome comprises a variety of physical, psychiatric, and cognitive features. Recent evidence suggests that patients are prone to severe language impairments. However, it remains unclear whether verbal impairments are pervasive at all levels of language, or whether one domain is relatively more spared than others. Here we document the language profile of one patient with triple X, using standardized language tests and reports. Results concur in showing that impairments are noticeable both in expressive and receptive language skills, and in vocabulary as well as in structural components of language. Although receptive ability in some tests appears relatively spared, even here A's performance is clearly below average. This single case study further underscores that language and communication at all levels can be severely compromised in patients with triple X. Practitioners should be aware of the limited language abilities that possibly exist in patients with triple X.

Loci of stuttering of English- and Korean-speaking children who stutter: Preliminary findings.

PURPOSE: The purpose of the study was to determine whether differences exist between young English- and Korean-speaking children who stutter (CWS) in the loci of stuttering. METHOD: Participants were 10 Korean-speaking and 11 English-speaking CWS between the ages of 3 and 7 years. Participants produced narratives while viewing various picture scenes and a wordless picture book. RESULTS: Findings indicated that Korean-speaking CWS stuttered more on content than function words whereas English-speaking CWS stuttered more on function than content words. Furthermore, both Korean- and English-speaking CWS tended to stutter more on utterance-initial words. These findings appear to be related to the differences in linguistic/syntactic structures between Korean and English. Specifically, in the Korean-speaking CWS's narratives, most utterance-initial words (73.60 %) were content words whereas in the English-speaking CWS's narratives, most utterance-initial words (83.57 %) were function words. CONCLUSION: These preliminary findings, although in need of replication with a larger sample size, seem to suggest that the word class (i.e., content/function words) contributions to stuttering loci are more language-specific whereas the word position (i.e., utterance-initial position) contributions to stuttering loci are more language-nonspecific. Given that the true characteristics of stuttering may be rather language-nonspecific than language-specific, further research may need to focus more on stuttering loci related to word position than word class.

Validation of the Manchester spoken language development scale (MSLDS).

Introduction: Standardized outcome measures are importantfor accurately monitoring the language development of pre-lingually deaf children receiving auditory implants. Current commonly used outcome measures are time-consuming,limiting the practicality of regular testing. To address these limitations, the Manchester Spoken Language Development Scale (MSLDS) was developed as a quick and easily applicable interim measurement. This is an 11-point scale designed to provide a streamlined overview of a child's expressive language development. This study describes the MSLDS, evaluates its ease of use and inter-rater reliability, and outlines its application in the paediatric auditory implant population. Methods: Sixteen speech therapists and teachers for the deaf reviewed videos of paediatric cochlear implant assessmentsand rehabilitation sessions at a UK auditory implant centre. Twenty-five videos from fourteen children were used in this validation study. Reviewers were asked to evaluate a child's language development using the MSLDS by assigning a score for each video and to evaluate the ease of use of the scale. Each video wasrated by three different reviewers. Results: MSLDS scores showed a high degree of consistency between raters for each child. 8/25 (32%) videos demonstrated perfect agreement on the MSLDS. In 15/25 (60%) videos, there was a one-point difference between MSLDS scores. The remaining 2/25 (8%) videos varied by 2 points. Statistical analysis demonstrated an intra-class correlation coefficient (ICC) of 0.987, indicating a high level of agreement between users of the scale. Qualitative feedback from the raters suggested further modifications which have been incorporated into the scale. Conclusion: The high inter-rater agreement reflects the potential for the MSLDS to be a reliable tool for monitoring language development in the paediatric auditory implant population.

How Much Time Do People With Aphasia Need to Respond During Picture Naming? Estimating Optimal Response Time Cutoffs Using a Multinomial Ex-Gaussian Approach.

Purpose Aphasia is a language disorder caused by acquired brain injury, which generally involves difficulty naming objects. Naming ability is assessed by measuring picture naming, and models of naming performance have mostly focused on accuracy and excluded valuable response time (RT) information. Previous approaches have therefore ignored the issue of processing efficiency, defined here in terms of optimal RT cutoff, that is, the shortest deadline at which individual people with aphasia produce their best possible naming accuracy performance. The goals of this study were therefore to (a) develop a novel model of aphasia picture naming that could accurately account for RT distributions across response types; (b) use this model to estimate the optimal RT cutoff for individual people with aphasia; and (c) explore the relationships between optimal RT cutoff, accuracy, naming ability, and aphasia severity. Method A total of 4,021 naming trials across 10 people with aphasia were scored for accuracy and RT onset. Data were fit using a novel ex-Gaussian multinomial RT model, which was then used to characterize individual optimal RT cutoffs. Results Overall, the model fitted the empirical data well and provided reliable individual estimates of optimal RT cutoff in picture naming. Optimal cutoffs ranged between approximately 5 and 10 s, which has important implications for assessment and treatment. There was no direct relationship between aphasia severity, naming RT, and optimal RT cutoff. Conclusion The multinomial ex-Gaussian modeling approach appears to be a promising and straightforward way to estimate optimal RT cutoffs in picture naming in aphasia. Limitations and future directions are discussed.

The development and validation of the Short Language Measure (SLaM): A brief measure of general language ability for children in their first year at school.

BACKGROUND: There is no sufficiently accurate short-language measure that could be used by speech-language pathologists, teachers or paraprofessionals to screen young school-aged children to identify those requiring in-depth language evaluations. This may be due to poor development of the available measures, which have omitted crucial test development steps. Applying more stringent development procedures could result in a measure with sufficient accuracy. AIMS: To create and validate a short-language measure that has acceptable accuracy, validity and reliability, and which can be used to identify children who require further assessment and/or referral to speech-language services. METHODS & PROCEDURES: The study consisted of two phases. In Phase 1 (measure creation), 56 children were assessed with 160 direction-following and sentence-recall test items and a reference measure, the Clinical Evaluation of Language Fundamentals-Fourth Edition (CELF-4). Items were then examined for their individual characteristics (validity, reliability, difficulty and discrimination) via item analysis and the highest quality items were selected to form the Short Language Measure (SLaM). In Phase 2 (measure validation), 126 children were assessed with the SLaM and the reference measure (CELF-4) to determine SLaM's accuracy, validity and reliability. OUTCOMES & RESULTS: A total of 40 test items were selected to form SLaM in Phase 1. Findings from Phase 2 indicated that SLaM had an accuracy of 94% (sensitivity = 94%, specificity = 93%), validity of 0.89 and reliability of 0.93. These values remained relatively consistent across both phases. CONCLUSIONS & IMPLICATIONS: The results indicated that SLaM has excellent psychometric properties. It can be used to identify children who need further evaluation by a speech-language pathologist. What this paper adds What is already known on this subject Prior research suggests that combining a direction-following and a sentence-recall task has sufficient discrimination accuracy and agreement with an omnibus language measure. Trialling a large set of direction-following and sentence-recall test items to select those with the highest individual characteristics could result in an effective short-language measure. What this paper adds to existing knowledge A short-language measure (SLaM) was created and validated on two independent samples of children. Items with the highest validities, reliabilities and discrimination capacities were selected to form SLaM. This procedure resulted in a measure with high validity and reliability that exceeded the criterion for adequate discrimination accuracy. What are the potential or actual clinical implications of this work? SLaM is an effective measure that can accurately identify children who require detailed evaluations by speech-language pathologists.

Examination of the reliability and validity of the NAB Naming Test in a diverse clinical sample.

Objective: The Boston Naming Test, Second Edition (BNT-2) and the Neuropsychological Assessment Battery (NAB) Naming Test are common measures to assess visual confrontation naming ability. The comparably newer NAB Naming Test is a potential alternative to the BNT-2, given the latter's history of criticism. A recent psychometric investigation of the NAB Naming Test demonstrated sufficient reliability and validity in a large clinical sample; however, their study was limited by a lack of ethnic, racial, and language diversity, all of which can impact scores on naming tests.Method: The present study examined convergent and discriminant validity and internal consistency of the NAB Naming Test in a diverse clinical sample comprised of 225 veterans (87.6% men, 51.1% White/Caucasian, 29.3% bilingual, 64.0% with cognitive impairment). All but three participants identified as White/Caucasian, Hispanic/Latino or Black/African American. These psychometric properties were examined for the overall sample and for monolingual (English) and bilingual (English/Spanish) participants separately.Results: As expected, the NAB Naming Test demonstrated sufficient internal consistency and a negatively skewed distribution for the overall sample and monolingual and bilingual participants. Evidence for adequate convergent and discriminative validity was also established for monolingual and bilingual participants separately.Conclusion: In a diverse clinical sample with differing levels of self-reported language status, the NAB Naming Test demonstrated adequate psychometric properties. Although it represents a viable option in neuropsychological practice, continued awareness of patient-specific factors that could impact performance is recommended.
