Purpose: Several studies have demonstrated that dynamic assessment can be a less biased, valid approach for the identification of language disorder among diverse school-age children. However, all prior studies have included a relatively small number of participants, which is generally not adequate for psychometric research. This is the first…

Purpose: Intentional communication acts, or purposefully directed vocalizations and gestures, are particularly difficult for infants at elevated likelihood for eventual diagnosis of autism. The ability to measure and track intentional communication in infancy thus has the potential to aid early identification and intervention efforts. This study…

Purpose: The aim of this study was to investigate the extent to which researchers in the field of developmental language disorder are utilizing validated methods to diagnose their research participants. Method: We examined 90 research articles published from 2015 to 2019 that included English-speaking participants from the United States who were…

Purpose: The purpose of this study was to extend the assessment of the psychometric properties of the Modified Barium Swallow Impairment Profile (MBSImP). Here, we re-examined structural validity and internal consistency using a large clinical-registry data set and formally examined rater reliability in a smaller data set. Method: This study…

Purpose: In this article, the authors report reliability and validity evidence for the Dynamic Evaluation of Motor Speech Skill (DEMSS), a new test that uses dynamic assessment to aid in the differential diagnosis of childhood apraxia of speech (CAS). Method: Participants were 81 children between 36 and 79 months of age who were referred to the…

Purpose: To date, there is no tool for assessing early pragmatic development of Polish-speaking children. This study aimed to adapt to Polish a standardized parent report measure, the Language Use Inventory (LUI; O'Neill, 2009, in order to enable cross-cultural comparisons and to use the LUI-Polish to screen for pragmatic development in children…

Purpose: To demonstrate the internal reliability and discriminative validity of the Language Use Inventory for Young Children (LUI; D. K. O'Neill, 2002), a newly developed parent-report measure designed to assess pragmatic language development in 18-47-month-olds. Method: To examine internal reliability, the LUI was completed by mail by 177…

Three studies with approximately 600 children were conducted to evaluate the validity and reliability of the three measures of the Communication and Symbolic Behavior Scales Developmental Profile. Findings support the use of the profile as a screening and evaluation tool for identifying children with developmental delays at 12 to 24 months of age.…

Voice range profiles (VRP) were analyzed according to 11 frequency, intensity, and morphological characteristics for 94 typical children and 136 children with vocal fold pathologies (ages 6-11). Normative data are presented showing marked differences between the groups. The use of the VRP Index for Children for screening is discussed. (Author/CR)

Two studies are reported demonstrating the reliability, validity, and clinical utility of the Language Development Survey (LDS) as a screening tool for the identification of expressive language delay in toddlers. The LDS test-retest reliability was .97. The LDS also correlated highly with other measures and the LDS identified at-risk group scored…

Two studies investigated a brief, processing-dependent, nonword repetition task, designed to minimize biases associated with traditional language tests. Results revealed that nonword repetition distinguished between school-age children independently identified as language impaired or normally developing, suggesting its potential usefulness as a…

Purpose: To evaluate the effectiveness of a screening instrument (the Swedish Communication Screening at 18 months of age; SCS18), derived from the Swedish MacArthur-Bates Communicative Development Inventory, in identification of 18-month-old children who will be severely language disabled by 3 years of age, the authors (a) analyzed which SCS18's…
