Vocabulary Gains in Bilingual Narrative Intervention.

Purpose The purpose of the current study was to evaluate the effect of bilingual narrative intervention on vocabulary gains in Hebrew (school language) and English (home language) among English-Hebrew bilinguals, using a block design (one language at a time), and to determine whether there was cross-linguistic transfer to the language that was not receiving intervention. Method Sixteen English-Hebrew bilingual children participated in the study using an adaptation of the Puente de Cuentos intervention. Vocabulary was examined using a word definition task before the intervention, post English intervention, post Hebrew intervention, and 4 weeks after the interventions ended to examine maintenance of skills. Results Repeated-measures analyses of variance revealed that children made significant gains in vocabulary in the language of intervention as expected. In addition, children made cross-linguistic gains in Hebrew during the English intervention, but made no gains in English following Hebrew intervention. Conclusion These results underscore the need to provide language support in the home language to ensure growth and that intervention in the home language does not hinder growth in the school language.

Effects of a Family Literacy Program for Latino Parents: Evidence From a Single-Subject Design.

Purpose This study investigated the effects of a family literacy program on Latino parents' language practices at home and their children's oral language skills. The study examined the extent to which (a) the program called Family Reading Intervention for Language and Literacy in Spanish was effective at teaching low-income, low-education Latino parents 3 language strategies (i.e., comments, high-level questions, and recasts) for reading aloud and (b) parent implementation of the target strategies influenced children's language skills. Method Five Latino mothers and their Spanish-speaking preschool children participated in a multiple-baseline, single-subject design across participants. Program initiation was staggered across the mothers after obtaining a stable baseline. Data on parent and child outcomes were collected across 3 experimental conditions: baseline, intervention, and follow-up. This study employed visual data analysis (e.g., level, trend, variability) to examine the program effects on parent and child outcomes. Results The program had an important effect on parental use of comments and high-level questions, but less impact on recasts. In addition, the program had a notable effect on the children's use of different words and conversational turns, less effect on inferences, and no effect on the mean length of utterance in words. Conclusion Family Reading Intervention for Language and Literacy in Spanish is an effective program to extend and enrich the reading practices that low-income children from a culturally and linguistically diverse background experience at home. The results have implications for family literacy programs aimed at minority Spanish-speaking families.

Performance of Low-Income Dual Language Learners Attending English-Only Schools on the Clinical Evaluation of Language Fundamentals-Fourth Edition, Spanish.

Purpose: The aim of this study was to examine the performance of a group of Spanish-speaking, dual language learners (DLLs) who were attending English-only schools and came from low-income and low-parental education backgrounds on the Clinical Evaluation of Language Fundamentals-Fourth Edition, Spanish (CELF-4S; Semel, Wiig, & Secord, 2006). Method: Spanish-speaking DLLs (N = 656), ages 5;0 (years;months) to 7;11, were tested for language impairment (LI) using the core language score of the CELF-4S and the English Structured Photographic Expressive Language Test (Dawson, Stout, & Eyer, 2003). A subsample (n = 299) was additionally tested using a Spanish language sample analysis and a newly developed Spanish morphosyntactic measure, for identification of children with LI and to conduct a receiver operating characteristics curve analysis. Results: Over 50% of the sample scored more than 1 SD below the mean on the core language score. In our subsample, the sensitivity of the CELF-4S was 94%, and specificity was 65%, using a cutoff score of 85 as suggested in the manual. Using an empirically derived cutoff score of 78, the sensitivity was 86%, and the specificity was 80%. Conclusions: Results suggest that the CELF-4S overidentifies low-income Spanish-English DLLs attending English-only schools as presenting with LI. For this sample, 1 in every 3 Latino children from low socioeconomic status was incorrectly identified with LI. Clinicians should be cautious when using the CELF-4S to evaluate low-income Spanish-English DLLs and ensure that they have converging evidence before making diagnostic decisions.

Language Sample Analysis and Elicitation Technique Effects in Bilingual Children With and Without Language Impairment.

Purpose: This study examined whether the language sample elicitation technique (i.e., storytelling and story-retelling tasks with pictorial support) affects lexical diversity (D), grammaticality (grammatical errors per communication unit [GE/CU]), sentence length (mean length of utterance in words [MLUw]), and sentence complexity (subordination index [SI]), which are commonly used indices for diagnosing primary language impairment in Spanish-English-speaking children in the United States. Method: Twenty bilingual Spanish-English-speaking children with typical language development and 20 with primary language impairment participated in the study. Four analyses of variance were conducted to evaluate the effect of language elicitation technique and group on D, GE/CU, MLUw, and SI. Also, 2 discriminant analyses were conducted to assess which indices were more effective for story retelling and storytelling and their classification accuracy across elicitation techniques. Results: D, MLUw, and SI were influenced by the type of elicitation technique, but GE/CU was not. The classification accuracy of language sample analysis was greater in story retelling than in storytelling, with GE/CU and D being useful indicators of language abilities in story retelling and GE/CU and SI in storytelling. Conclusion: Two indices in language sample analysis may be sufficient for diagnosis in 4- to 5-year-old bilingual Spanish-English-speaking children.

Evaluating the discriminant accuracy of a grammatical measure with Spanish-speaking children.

PURPOSE: The purpose of this study was to evaluate the discriminant accuracy of a grammatical measure for the identification of language impairment in Latino Spanish-speaking children. The authors hypothesized that if exposure to and use of English as a second language have an effect on the first language, bilingual children might exhibit lower rates of grammatical accuracy than their peers and be more likely to be misclassified. METHOD: Eighty children with typical language development and 80 with language impairment were sampled from 4 different geographical regions and compared using linear discriminant function analysis. RESULTS: Results indicated fair-to-good sensitivity from 4;0 to 5;1 years, good sensitivity from 5;2 to 5;11 years, and poor sensitivity above age 6 years. The discriminant functions derived from the exploratory studies were able to predict group membership in confirmatory analyses with fair-to-excellent sensitivity up to age 6 years. Children who were bilingual did not show lower scores and were not more likely to be misclassified compared with their Spanish-only peers. CONCLUSIONS: The measure seems to be appropriate for identifying language impairment in either Spanish-dominant or Spanish-only speakers between 4 and 6 years of age. However, for older children, supplemental testing is necessary.

Assessing Measurement Invariance for Spanish Sentence Repetition and Morphology Elicitation Tasks.

PURPOSE: The purpose of this study was to evaluate evidence supporting the construct validity of two grammatical tasks (sentence repetition, morphology elicitation) included in the Spanish Screener for Language Impairment in Children (Restrepo, Gorin, & Gray, 2013). We evaluated if the tasks measured the targeted grammatical skills in the same way across predominantly Spanish-speaking children with typical language development and those with primary language impairment. METHOD: A multiple-group, confirmatory factor analytic approach was applied to examine factorial invariance in a sample of 307 predominantly Spanish-speaking children (177 with typical language development; 130 with primary language impairment). The 2 newly developed grammatical tasks were modeled as measures in a unidimensional confirmatory factor analytic model along with 3 well-established grammatical measures from the Clinical Evaluation of Language Fundamentals-Fourth Edition, Spanish (Wiig, Semel, & Secord, 2006). RESULTS: Results suggest that both new tasks measured the construct of grammatical skills for both language-ability groups in an equivalent manner. CONCLUSIONS: There was no evidence of bias related to children's language status for the Spanish Screener for Language Impairment in Children Sentence Repetition or Morphology Elicitation tasks. Results provide support for the validity of the new tasks as measures of grammatical skills.

Language Ability Groups in Bilingual Children: A Latent Profile Analysis.

PURPOSE: Classifying children into two language ability groups, with and without language impairment, may underestimate the number of groups with distinct language ability patterns, or, alternatively, there may be only a single group characterized by a continuum of language performance. The purpose of the current study was to identify the number and characteristics of latent (unobservable) language ability groups in an unclassified sample of predominantly Spanish-speaking children. METHOD: An unclassified sample of 431 predominantly Spanish-speaking 5- to 7-year-olds learning English participated in the study. The groups were identified on the basis of (a) language sample analyses (semantic, grammatical, and sentence-length measures); (b) language processing tasks (phonological working memory and processing speed measures); and (c) nonverbal cognitive abilities assessed using a standardized measure. All tasks were administered in Spanish. Latent profile analysis was used to examine the number and nature of distinct language ability groups in the unclassified sample. RESULTS: Results indicated that a three-group model best represented the data, characterized by low grammaticality in one group, low phonological working memory in another group, and average skills in a third group. CONCLUSION: Classifying children into two groups, those with and without language impairment, may lead to misidentification of language impairment.

Statistical analyses of structural magnetic resonance imaging of the head of the caudate nucleus in Colombian children with attention-deficit hyperactivity disorder.

Magnetic resonance imaging (MRI) studies of the caudate nucleus have reported reversal asymmetry and alterations of its size, suggesting a striate cortical disorder related to attention-deficit hyperactivity disorder (ADHD). The objective was to evaluate whether alterations of the asymmetry and size of the caudate nucleus head exist in a sample of well-controlled 7- to 11-year-old Colombian children, with different types of ADHD. Two groups of cases-ADHD of the combined type and ADHD of the inattentive type-and one control group, were selected. Multiple methods for assessing ADHD (rating scales, psychologic.interview, neurologic history and examination, and neuropsychologic evaluation) were used to confirm the diagnoses. Participants with a history of language disorder, learning disabilities, depression, and other major neurologic and psychiatric conditions were excluded. Finally all groups had 15 children, matched by sex (7 male, 8 female), age, socioeconomic status, and grade. Height, weight, head circumference, and encephalic index were statistically controlled. Three T1-weighted volumetric (three-dimensional) MRI slides of the caudate nucleus head were obtained with a 1.5-Tesla Gyroscan apparatus. The control group had a significantly higher Wechsler Full-Scale IQ than the groups with ADHD of the combined type and ADHD of the inattentive type (P < .001). Volumes from the left caudate nucleus head were significantly larger than volumes from the right in all groups (P < .001). There were no group differences when volumes were compared between groups. All of the groups had left caudate nucleus head volumes significantly higher than right, although there were no between-group differences. The results in relation to previous studies are discussed.

Development and validation of the Spanish-English Language Proficiency Scale (SELPS).

PURPOSE: This study examined the development and validation of a criterion-referenced Spanish-English Language Proficiency Scale (SELPS) that was designed to assess the oral language skills of sequential bilingual children ages 4-8. This article reports results for the English proficiency portion of the scale. METHOD: The SELPS assesses syntactic complexity, grammatical accuracy, verbal fluency, and lexical diversity based on 2 story retell tasks. In Study 1, 40 children were given 2 story retell tasks to evaluate the reliability of parallel forms. In Study 2, 76 children participated in the validation of the scale against language sample measures and teacher ratings of language proficiency. RESULTS: Study 1 indicated no significant differences between the SELPS scores on the 2 stories. Study 2 indicated that the SELPS scores correlated significantly with their counterpart language sample measures. Correlations between the SELPS and teacher ratings were moderate. CONCLUSIONS: The 2 story retells elicited comparable SELPS scores, providing a valuable tool for test-retest conditions in the assessment of language proficiency. Correlations between the SELPS scores and external variables indicated that these measures assessed the same language skills. Results provided empirical evidence regarding the validity of inferences about language proficiency based on the SELPS score.

Dynamic assessment of word learning skills: identifying language impairment in bilingual children.

PURPOSE: Bilingual children are often diagnosed with language impairment, although they may simply have fewer opportunities to learn English than English-speaking monolingual children. This study examined whether dynamic assessment (DA) of word learning skills is an effective method for identifying bilingual children with primary language impairment (PLI). METHOD: Fifteen 4- and 5-year-old predominantly Spanish-speaking children with typical language development (TLD) and 13 with PLI each participated in a 30- to 40-min session of DA of word learning skills following a pretest-teach-posttest design. RESULTS: Results indicated that TLD children made associations between the phonological and semantic representations of the new words faster than children with PLI did, showing greater modifiability. Further, a combination of word learning in the receptive modality and the Learning Strategies Checklist (Lidz, 1991; Peña, 1993) provided the best accuracy in identifying PLI in these children. CONCLUSION: Findings suggest that a brief DA is a promising method for accurately differentiating children with TLD from children with PLI.

Effects of a supplemental Spanish oral language program on sentence length, complexity, and grammaticality in Spanish-speaking children attending English-only preschools.

PURPOSE: The purpose of this study was to examine the effects of a supplemental Spanish language instruction program for children who spoke Spanish as their native language and were attending English-only preschool programs. Specifically, the study evaluated the program's effects on the children's Spanish sentence length in words, subordination index, and grammaticality of sentences. METHOD: Forty-five Spanish-speaking children attending English-only prekindergarten classrooms were selected for study. Of those, 15 children received 30 min of Spanish instruction 5 days a week for 16 weeks. The program targeted 5-10 vocabulary words a week, dialogic book reading, phonemic awareness, and letter knowledge. The remaining 30 children participated in regular preschool English instruction. Students were evaluated before intervention, immediately after intervention, and 4 months following intervention. RESULTS: Repeated measures analyses of variance indicated that the children who received the small-group supplemental Spanish language instruction made significant gains in their Spanish sentence length in words and subordination index when compared to those receiving regular English-only classroom instruction. There were no differences in the children's grammaticality of sentences. DISCUSSION AND CLINICAL IMPLICATIONS: The findings demonstrate that a daily short native language program has significant effects on sentence length in words and subordination index in English language learners who are attending English-only preschool programs.

Language Sample Analysis in Spanish-Speaking Children: Methodological Considerations.

The purposes of this article are (a) to discuss issues related to the selection and development of language assessment procedures for children who speak Spanish and English based on spontaneous language samples and (b) to show how available procedures can be applied to research and clinical aims with these children. Sociolinguistic influences in the language performance of Spanish-speaking children, including patterns of language shift, differences in the amount of exposure to each of a bilingual's languages, and contextual effects of different language-learning environments, are discussed. Methodological issues and effects of codeswitching and dialect are examined concerning use of the Developmental Assessment of Spanish Grammar (DASG), mean length of response in words (MLR-w), mean length of terminable unit (MLTU), and mean length of utterance in morphemes (MLU-m). Measures of Spanish grammar with diagnostic potential are proposed. Clinical suggestions for the language assessment of Spanish-speaking children with different levels of English proficiency and research implications are discussed.
