Assessing students with dyslexia and other reading difficulties through multiple diagnostic assessments.

This article aims to assist practitioners in understanding dyslexia and other reading difficulties and assessing students' learning needs. We describe the essential components of language and literacy, universal screening, diagnostic assessments, curriculum-based measurement and eligibility determination. We then introduce four diagnostic assessments as examples, including norm-referenced assessments (i.e. the Comprehensive Test of Phonological Processing second edition and the Woodcock-Johnson IV Tests of Achievement) and criterion-referenced assessments (i.e. the Gallistel-Ellis Test of Coding Skills and the Dynamic Indicators of Basic Early Literacy Skills). Finally, We use a makeup case as a concrete example to illustrate how multiple diagnostic assessments are recorded and how the results can be used to inform intervention and eligibility for special education services.

Measuring the complex syntax of school-aged children in language sample analysis: A known-groups validation study.

BACKGROUND: Complex syntax is affected by developmental language disorder (DLD) during the school years. Targeting areas of syntactic difficulty for children with DLD may yield useful assessment techniques. AIMS: To determine whether wh-movement can be measured in language samples from typically developing mono- and bilingual school-aged children, and, if so, to provide preliminary evidence of validity by comparison with traditional measures of syntax in a cross-sectional, known-groups design. METHODS & PROCEDURES: Participants were 48 typically developing children recruited from the Canadian province of Nova Scotia in four groups: monolingual English and bilingual French-English children in early (7-8 years of age) and late (11-12 years of age) elementary school. Language samples were collected and analysed with mean use of wh-movement, mean length of utterance and clausal density. These measures were compared for effects of age, bilingual development and elicitation task. OUTCOMES & RESULTS: The results from all measures closely paralleled each other, providing preliminary evidence of validity. Wh-movement-based and traditional measures demonstrated similar age-related and discourse genre effects. Neither demonstrated an effect of mono- versus bilingual development. CONCLUSIONS & IMPLICATIONS: The results confirm research interest in syntactic movement as an area of language assessment. Further research is required to understand its application to clinical populations. What this paper adds What is already known on the subject Complex syntax is known to be an area of difficulty for children with DLD. Certain syntactic constructions appear to be particularly difficult for these children. Assessments targeting these areas of difficulty are emerging. What this paper adds to existing knowledge The paper compares traditional measures of syntax with measures based on wh-movement. It shows similar results for both types of measures, suggesting construct and convergent validity. Results suggest that syntactic movement is an age-appropriate area of assessment for elementary school-aged children's language. What are the potential or actual clinical implications of this work? Language sample assessment measures based on wh-movement appear promising. The impact of task effects of the discourse genre on assessing syntax must be carefully considered in research and clinical practice.

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.

Gaze and Motor Traces of Language Processing: Evidence from Autism Spectrum Disorders in Comparison to Typical Controls.

We investigated what strategies underlie figurative language processing in two groups of participants distinguished by the presence of a developmental deficit, highly-verbal participants with autism, and control participants without autism in two age ranges each. Individuals with autism spectrum disorder are characterised by impaired social interaction and communication. Even at the high end of the spectrum, where structural language is adequate, difficulties in comprehending non-literal aspects of language are widely attested. The exact causes of these problems are, however, still open to debate. In an interactive sentence-picture matching task participants selected the most suitable image representation of a non-literal figurative expression that matched the target meaning, while their eye-movements and hand movements were being tracked. Our results suggest that individuals with ASD have different processing patterns than typically developing peers when interpreting figurative language, even when they provide the correct answers. Both children with and without autism, and participants with autism display greater uncertainty and competition between alternatives when providing the answer, often reflected in also considering the literal interpretation of the expression against its target figurative meaning. We provide evidence that expression transparency and decomposability play a central role in figurative language processing across all groups.

The Factor Structure of the Boston Diagnostic Aphasia Examination, Third Edition.

OBJECTIVE: The Boston Diagnostic Aphasia Examination (BDAE) is one of the most commonly used aphasia batteries. The newest edition has undergone significant revisions since its original publication in 1972, but existing evidence for its validity is lacking. We examined the construct validity of BDAE-3 and identified the factor structure of this battery. METHOD: A total of 355 people with aphasia of various types and severity completed neuropsychological evaluations to assess their patterns of language impairment. A principal component analysis with varimax rotation was conducted to examine the components of BDAE-3 subtests. RESULTS: Five components accounting for over 70% of the BDAE-3 total variance were found. The five language factors identified were auditory comprehension/ideomotor praxis, naming and reading, articulation-repetition, grammatical comprehension, and phonological processing. CONCLUSIONS: Our results show that the BDAE-3 demonstrates good construct validity, and certain language functions remain primary, distinct language domains (i.e., receptive vs. expressive language) across severities of aphasia. Overall, our findings inform clinical practice by outlining the inherent structure of language abilities in people with aphasia. Clinicians can utilize the findings to select core BDAE-3 tests that are most representative of their respective functions, thereby reducing the total testing time while preserving diagnostic sensitivity.

Validation of the Thai version of the short Boston Naming Test (T-BNT) in patients with Alzheimer's dementia and mild cognitive impairment: clinical and biomarker correlates.

OBJECTIVES: Impairments in the Boston Naming Test (BNT), which measures confrontational word retrieval, frequently accompanies Alzheimer's dementia (AD) and may predict a more rapid progression of illness. This study aims to validate the Thai version of the 15-item BNT (T-BNT) in participants with AD and amnestic mild cognitive impairment (aMCI) and to externally validate the T-BNT using clinical and biomarker measurements. METHODS: This cross-sectional study recruited patients with AD, diagnosed according to NINCDS-ADRDA criteria (n = 60), aMCI, diagnosed using the Petersen criteria (n = 60), and healthy controls (n = 62). We examined the internal consistency, concurrent and discriminant reliability of the T-BNT. We also assessed the Mini Mental State Examination (MMSE), the Verbal Fluency Test (VFT) and the Word List Memory (WLM) tests and measured apolipoprotein E polymorphism and serum levels of folic acid, high-density lipoprotein cholesterol (HDL) and triglycerides. RESULTS: This study validated a 10-item T-BNT (10T-BNT), which yielded good internal consistency (0.92), a one-factor unidimensional structure, and adequate concurrent and discriminant validity. Lower scores on the 10T-BNT highly significantly predict AD, but not aMCI, and are positively associated with VFT and WLM test scores. Furthermore, lowered 10T-BNT scores are significantly associated with the ApoE4 allele, lower folate levels and an increased triglyceride/HDL-cholesterol ratio. CONCLUSIONS: This study validated the 10T-BNT and the total score on this scale is strongly associated with AD, impairments in semantic and episodic memory and biomarkers, which are known to modify memory via different mechanisms.

Early lexicon and language skills at 42 months.

Previous studies have shown that early lexical development is associated with later language development. It is less clear which language domains early receptive/expressive lexicons are associated with. This study analyses these associations. The study also investigates whether children with slow/typical/fast developing early receptive/expressive lexical skills differed in their language skills at three and a half years (42 months) and the predictive value of early receptive/expressive lexical skills for later language skills. The participants of this longitudinal study were 68 healthy, monolingual Finnish-speaking children whose language development was measured using the Finnish, short-form-version of the Communicative Development Inventories at 12, 15, 18 and 24 months. At 42 months, language skills of the participants were assessed using tests measuring lexical, phonological, morphological and general receptive/expressive language skills. Early receptive lexicon was associated with later morphological skills from 15 months and onwards and with other language domains at 24 months. Early expressive lexicon was associated with later morphological skills at 15 months and onwards but with other language domains from 18 months. A trend was found that children with different early lexical growth rates differed in their language skills at 42 months. The best models for predicting later receptive/expressive language skills included variables from both early receptive and expressive lexicons. These models worked well to explain receptive/expressive language skills at 42 months (63/78% of the variance). This study provides novel information on the specific associations between receptive and expressive lexicon growth and later language skills. For clinicians, measuring both receptive and expressive lexicons provides the most representative information on children's language development.

Exploring the Relationship between Native Language Skills and Foreign Language Learning in Children with Developmental Language Disorders.

Learning English as a foreign language (FL) is mandatory for children with developmental language disorders (DLD) in elementary education in the Netherlands. Because of their difficulties in acquiring their first language, learning an FL at school can be challenging. To date, almost no literature on children with DLD and FL learning exists. The aim of this study is to investigate the relationship between language proficiency in Dutch of monolingual and multilingual children with DLD and learning English as an FL. A cross-sectional study was conducted in four special education schools for children with DLD. Thirty-five sixth graders (mean age 12;3 years) participated in this study. Twenty-two children were monolingual, and 13 children were multilingual. Correlation analyses between scores on standardised Dutch language tests and a standardised test for English proficiency were performed. Because the English proficiency test partly relies on reading skills, scores on a Dutch word decoding test were included in the analyses. Results show that the children with DLD performed poorly on the FL proficiency test when compared to typically developing children. Significant positive relationships were found between Dutch and English language skills of children with DLD, with no significant differences in FL proficiency between the monolingual and multilingual groups. Possibly, children with DLD cannot achieve acceptable proficiency levels of English as an FL, because of poor word decoding skills and impaired morphosyntactic skills in Dutch. Future research should focus on oral English proficiency of the children, because the English proficiency test only uses written and auditory presented tasks.

Development of a language screening instrument for Swedish 4-year-olds.

BACKGROUND: The Swedish Program for health surveillance of preschool children includes screening of language and communication abilities. One important language screening is carried out at age 4 years as part of a general screening conducted by health nurses at child health centres. The instruments presently in use for this screening mainly focus on expressive phonology. This may result in both over-referral of children with phonological difficulties and under-referral of children with language disorders (LDs), involving difficulties with vocabulary, grammar and/or language comprehension. Previous research has proposed non-word repetition as a clinical marker for LD. It has also been found that higher predictive power is achieved when non-word repetition is combined with the assessment of lexical/semantic skills. Taking these findings into account, the construction of a language screening instrument may yield more adequate referrals to speech-language therapists (SLTs). AIMS: To construct a new standardized language screening instrument for 4-year-olds and to test its properties. METHODS & PROCEDURES: An instrument was developed and revised after piloting. A population of 352 children was screened at the regular 4-year check-up by 11 health nurses. The final sample consisted of 328 children aged 46-53 months (23% multilingual). Children performing below a preliminary cut-off were referred to an SLT (n = 52). Five SLTs carried out an assessment on average within 5 weeks using a gold standard language test battery. Children who screened negatively were followed up with a parent questionnaire at age 5;6. OUTCOMES & RESULTS: Thirty-one true-positives and 11 false-positives were identified after SLT assessment. A further six children were identified as false-negatives (two through referral to an SLT and four through parent questionnaire at age 5;6). A receiver-operating characteristics curve with a C statistic of .94 was calculated. Based on optimal cut-off, the sensitivity of the screening instrument was found to be .84, and specificity was .96. Multilingual children performed similar to monolingual children; boys performed significantly lower than girls; and children with a family history of language-related problems performed lower than those without. Interrater reliability was high, as was Cronbach's alpha. CONCLUSIONS & IMPLICATIONS: The screening instrument seems sufficiently valid for its purpose to identify children who need further assessment by an SLT. A follow-up study including SLT assessment for all children to check for false-negatives would be interesting in future, as would studies comparing results from the 4-year screening with those from earlier screens.

Reliability and validity of the Korean-language version of the Communication Function Classification System in children with cerebral palsy.

PURPOSE: The Communication Function Classification System (CFCS) and Viking Speech Scale (VSS) are useful systems for describing the broad communication function and speech intelligibility, respectively, of children with cerebral palsy (CP). The aims of this study were to determine the reliability and validity of the Korean version of the CFCS and also to investigate the association between the CFCS and the VSS and other functional classifications for children with CP. MATERIALS AND METHODS: Participants were 50 children with CP (33 males, 17 females; mean age 7.2 years, range 4-16 years) recruited from a rehabilitation hospital. We analysed the interrater and intrarater reliabilities of the Korean version of the CFCS and VSS between parents, a physiatrist, and a speech-language pathologist (SLP). The social function domain of the Paediatric Evaluation of Disability Inventory was assessed to examine the concurrent validity of the CFCS and VSS. RESULTS: The intrarater reliabilities of the CFCS and VSS were excellent in a physiatrist (ƙ = 0.92, ƙ = 0.94, respectively) and an SLP (ƙ = 0.98, ƙ = 0.98) and very good in parents (ƙ = 0.87, ƙ = 0.89). The interrater reliability of the CFCS and VSS was very good between the physiatrist and SLP (ƙ = 0.87, ƙ = 0.89) and good between parents and the SLP (ƙ = 0.63, ƙ = 0.78) and between parents and the physiatrist (ƙ = 0.61, ƙ = 0.76). The CFCS and VSS were strongly related with the social function domain of Paediatric Evaluation of Disability Inventory. In addition, we found very strong associations between the VSS and CFCS. CONCLUSIONS: The Korean version of the CFCS is a valid and reliable tool to classify communication ability and is strongly associated with the VSS, a reliable tool to classify speech intelligibility.

Implementing a Standardized Assessment Battery for Aphasia in Acute Care.

In this article, the implementation of a standardized assessment battery for the evaluation of language in an acute care setting is described. Following an institutional shift to adopt electronic medical records, researchers and clinicians worked together to develop a technology-assisted evaluation of aphasia that would be used to assess all patients admitted to our facility with stroke. The project goal was to devise a clinical process to improve aphasia diagnosis and evaluation while remaining feasible within constraints imposed by the acute care setting and the electronic medical record. Utilizing frameworks from implementation science, the four key phases were: (1) initial considerations of the host setting, (2) creation of a structure for implementation, (3) maintenance of this structure once implementation began, and (4) improvement for future applications. A pilot implementation demonstrated that establishing and executing a minimum standardized assessment for aphasia in acute care is feasible. Retrospective medical record review of 50 aphasia evaluations in the setting of first incidence of left hemisphere stroke affecting the middle cerebral artery (25 preimplementation and 25 postimplementation) revealed that information content of medical notes was more consistent and complete postimplementation than preimplementation. Clinical implications and future directions are discussed.

Gulf Arabic nouns and verbs: A standardized set of 319 object pictures and 141 action pictures, with predictors of naming latencies.

Standardized pictorial stimuli and predictors of successful picture naming are not readily available for Gulf Arabic. On the basis of data obtained from Qatari Arabic, a variety of Gulf Arabic, the present study provides norms for a set of 319 object pictures and a set of 141 action pictures. Norms were collected from healthy speakers, using a picture-naming paradigm and rating tasks. Norms for naming latencies, name agreement, visual complexity, image agreement, imageability, age of acquisition, and familiarity were established. Furthermore, the database includes other intrinsic factors, such as syllable length and phoneme length. It also includes orthographic frequency values (extracted from Aralex; Boudelaa & Marslen-Wilson, 2010). These factors were then examined for their impact on picture-naming latencies in object- and action-naming tasks. The analysis showed that the primary determinants of naming latencies in both nouns and verbs are (in descending order) image agreement, name agreement, familiarity, age of acquisition, and imageability. These results indicate no evidence that noun- and verb-naming processes in Gulf Arabic are influenced in different ways by these variables. This is the first database for Gulf Arabic, and therefore the norms collected from the present study will be of paramount importance for researchers and clinicians working with speakers of this variety of Arabic. Due to the similarity of the Arabic varieties spoken in the Gulf, these different varieties are grouped together under the label "Gulf Arabic" in the literature. The normative databases and the standardized pictures from this study can be downloaded from http://qufaculty.qu.edu.qa/tariq-khwaileh/download-center/ .

Boston Naming Test (BNT) original, Brazilian adapted version and short forms: normative data for illiterate and low-educated older adults.

BACKGROUND: The aims of this study were (1) to describe and compare the performance of illiterate and low-educated older adults, without evidence of cognitive impairment, on different versions of the Boston Naming Test (BNT) original, Brazilian adapted, abbreviated 30-item (even and odd) and 15-item from the CERAD (Consortium to Establish a Registry for Alzheimer's Disease) battery; (2) to compare performance on the original versus adapted versions of the BNT. METHODS: A total of 180 healthy older adults (60 years or older) were stratified according to educational level (0, 1-2, and 3-4 years), and age (60-69, 70-79, and ≥ 80 years). The protocol comprised the following instruments: Mini-Mental State Examination (MMSE), Brief Cognitive Screening Battery (BCSB), Functional Activities Questionnaire (FAQ), Geriatric Depression Scale (GDS), and the BNT. RESULTS: The illiterate participants had poorer performance than the educated participants. The performance of the two educated groups was similar on all versions of the BNT. A higher number of correct responses were observed on the adapted BNT than on the original BNT in all three education groups. CONCLUSIONS: The adapted BNT appears to be the most suitable for use in the low-educated Brazilian population. The present study provided normative data for low-educated elderly on several different versions of the BNT, which may be helpful in diagnosing naming deficits among elderly in these strata of the population.

Development and Standardization of a Test for Pragmatic Language Skills in Egyptian Arabic: The Egyptian Arabic Pragmatic Language Test (EAPLT).

OBJECTIVE: The aim of this study was to standardize an Egyptian Arabic Pragmatic Language Test (EAPLT) using linguistically and socially suitable questions and pictures in order to be able to address specific deficits in this language domain. PARTICIPANTS AND METHODS: Questions and pictures were designed for the EAPLT to assess 3 pragmatic language subsets: pragmatic skills, functions, and factors. Ten expert phoniatricians were asked to review the EAPLT and complete a questionnaire to assess the validity of the test items. The EAPLT was applied in 120 typically developing Arabic-speaking Egyptian children (64 females and 56 males) randomly selected by inclusion and exclusion criteria in the age range between 2 years, 1 month, 1 day and 9 years, 12 months, 31 days. Children's scores were used to calculate the means and standard deviations and the 5th and 95th percentiles to determine the age of the pragmatic skills acquisition. RESULTS: All experts have mostly agreed that the EAPLT gives a general idea about children's pragmatic language development. Test-retest reliability analysis proved the high reliability and internal consistency of the EAPLT subsets. A statistically significant correlation was found between the test subsets and age. CONCLUSION: The EAPLT is a valid and reliable Egyptian Arabic test that can be applied in order to detect a pragmatic language delay.

Development of Bengali Audio-Visual Test Battery for Assessment of Pragmatic Skills: Preliminary Normative Data Based on Educational Level.

Pragmatic competence may be disrupted due to psychological and neurological causes. For appropriate remedy and rehabilitation, a precise assessment of pragmatic skills is important. However, there is no test battery in the Bengali language, and consequently, there is no published data on pragmatic ability of Bengali speakers. Due to the vast diversity of the population, it becomes increasingly difficult to assess pragmatic ability of an individual without a proper knowledge of the normal variations. To address this problem we have developed a test battery in Bengali, and to begin with, we have administered it to one hundred and five (105) normal healthy persons having different levels of education. The four groups having 17 years and above, 15 to < 17 years, 12 to < 15 years and 10 to < 12 years of education yielded a normative score of 193, 189, 171 and 150, respectively. These normative scores will allow clinicians to make a proper assessment of patients suffering from pragmatic deficits and help avoid interpreting social differences as neurological deficits.

Accounting for ethnic-cultural and linguistic diversity in neuropsychological assessment of patients with drug-resistant epilepsy: A retrospective study.

Neuropsychological assessment is critical in both diagnosis and prognosis of patients with epilepsy. Beyond electrophysiological and anatomical alterations, other factors including different ethnic-cultural and linguistic backgrounds might affect neuropsychological performance. Only a few studies considered migration and acculturation effects and they typically concerned nonclinical samples. The current study aimed at investigating the influence of ethnic background and time spent in Italy on a full neuropsychological battery administered to both Italian and foreign-born patients and at providing a brief interview for obtaining relevant information on each patient's transcultural and language-related history. Clinical reports from 43 foreign-born patients with drug-resistant epilepsy were collected from the archives of Milan Niguarda Hospital. Epileptogenic zone, age, education, profession, illness duration, seizure frequency, handedness, and gender were considered in selecting 43 Italian controls. Ethnicity (Italian/foreign-born) and years spent in Italy were analyzed as main predictors on 21 neuropsychological scales by means of General(ized) Linear Models. An additional analysis studied two composite scores of overall verbal and nonverbal abilities. Ethnicity significantly affected the following: the verbal overall score, Verbal Fluency, Naming, Token-test, Digit Span, Attentional Matrices, Trail-Making-Test, Line-Orientation-Test, and Raven matrices; no effects were found on the nonverbal overall score, Word Pairs Learning, Episodic Memory, reading accuracy, visual span, Bells test, Rey Figure, and face memory and recognition. No significant effects of years spent in Italy emerged. While years spent in Italy does not predict neuropsychological performance, linguistic background had a strong impact on it. With respect to Italian-speaking patients, those who were foreign-born showed large task-related variability, with an especially low performance on language-related tests. Hence, language tests should not be considered as valid measures of neuropsychological impairment in this population, not even in foreign-born patients with good Italian fluency. Clinicians should consider such asymmetries in order to improve the accuracy of neuropsychological assessment of foreign-born patients.

Reliability of the Dutch-language version of the Communication Function Classification System and its association with language comprehension and method of communication.

AIM: The aims of this study were to determine the intra- and interrater reliability of the Dutch-language version of the Communication Function Classification System (CFCS-NL) and to investigate the association between the CFCS level and (1) spoken language comprehension and (2) preferred method of communication in children with cerebral palsy (CP). METHOD: Participants were 93 children with CP (50 males, 43 females; mean age 7y, SD 2y 6mo, range 2y 9mo-12y 10mo; unilateral spastic [n=22], bilateral spastic [n=51], dyskinetic [n=15], ataxic [n=3], not specified [n=2]; Gross Motor Function Classification System level I [n=16], II [n=14], III, [n=7], IV [n=24], V [n=31], unknown [n=1]), recruited from rehabilitation centres throughout the Netherlands. Because some centres only contributed to part of the study, different numbers of participants are presented for different aspects of the study. Parents and speech and language therapists (SLTs) classified the communication level using the CFCS. Kappa was used to determine the intra- and interrater reliability. Spearman's correlation coefficient was used to determine the association between CFCS level and spoken language comprehension, and Fisher's exact test was used to examine the association between the CFCS level and method of communication. RESULTS: Interrater reliability of the CFCS-NL between parents and SLTs was fair (r=0.54), between SLTs good (r=0.78), and the intrarater (SLT) reliability very good (r=0.85). The association between the CFCS and spoken language comprehension was strong for SLTs (r=0.63) and moderate for parents (r=0.51). There was a statistically significant difference between the CFCS level and the preferred method of communication of the child (p<0.01). Also, CFCS level classification showed a statistically significant difference between parents and SLTs (p<0.01). INTERPRETATION: These data suggest that the CFCS-NL is a valid and reliable clinical tool to classify everyday communication in children with CP. Preferably, professionals should classify the child's CFCS level in collaboration with the parents to acquire the most comprehensive information about the everyday communication of the child in various situations both with familiar and with unfamiliar partners.

Reading Test-Sentence Comprehension: An Adapted Version of Lobrot's Lecture 3 Test for Brazilian Portuguese.

Our aim was to analyse the linguistic structure of the Lobrot's Lecture 3 (L3) reading test and to describe the procedure for its adaptation to a Brazilian cultural-linguistic context. The resulting adapted version is called the Reading Test-Sentence Comprehension [Teste de Leitura: Compreensão de Sentenças (TELCS)] and was developed using the European Portuguese adaptation of L3 as a reference. The present study was conducted in seven steps: (1) classification of the response alternatives of L3 test; (2) adaptation of the original sentences into Brazilian Portuguese; (3) back-translation; (4) adaptation of the distractors from TELCS; (5) configuration of TELCS; (6) pilot study; and (7) validation and standardization. In comparison with L3, TELCS included new linguistic and structural variables, such as frequency of occurrence of the distractors, gender neutrality and position of the target words. The instrument can be used for a collective screening or individual clinical administration purposes to evaluate the reading ability of second-to-fifth-grade and 7-to-11-year-old students.

Diagnosing bilectal children with SLI: Determination of identification accuracy.

Very little is known about diagnosing specific language impairment (SLI) in children who are exposed daily to a dialect (community language) and a standard variety (school instruction). The research reported here examines the specificity and sensitivity of language tests used so far to evaluate language performance in the context of diglossia (Cyprus). Sixteen children with SLI aged 5-9 years and 22 age-matched typically developing children were examined on a range of language tests modified to include dialectal differences. Properties of each test were evaluated through logistic regression analysis in order to identify children with SLI. The analysis revealed that many of the tests used are sufficiently accurate concerning sensitivity and specificity levels. Furthermore, a combination of tests is proposed as a good tool for diagnostic purposes. Speech and language therapists as well as researchers can now rely on an accurate diagnostic procedure within a practice-based evidence framework.

American Sign Language Comprehension Test: A Tool for Sign Language Researchers.

The American Sign Language Comprehension Test (ASL-CT) is a 30-item multiple-choice test that measures ASL receptive skills and is administered through a website. This article describes the development and psychometric properties of the test based on a sample of 80 college students including deaf native signers, hearing native signers, deaf non-native signers, and hearing ASL students. The results revealed that the ASL-CT has good internal reliability (α = 0.834). Discriminant validity was established by demonstrating that deaf native signers performed significantly better than deaf non-native signers and hearing native signers. Concurrent validity was established by demonstrating that test results positively correlated with another measure of ASL ability (r = .715) and that hearing ASL students' performance positively correlated with the level of ASL courses they were taking (r = .726). Researchers can use the ASL-CT to characterize an individual's ASL comprehension skills, to establish a minimal skill level as an inclusion criterion for a study, to group study participants by ASL skill (e.g., proficient vs. nonproficient), or to provide a measure of ASL skill as a dependent variable.
