A short form of the 60-item computer-based orthographic processing assessment (long-form COPA or COPA-LF) was developed. The COPA-LF consists of five skills, including rapid perception, access, differentiation, correction, and arrangement. Thirty items from the COPA-LF were selected for the short-form COPA (COPA-SF) based on cognitive diagnostic…

The Student Oral Language Observation Matrix (SOLOM) is an assessment of oral language skills. The aim of this study was to examine psychometric properties of the SOLOM for preschoolers through (a) use of internal consistency methods to assess the reliability of the scores from the SOLOM and (b) examination of criterion-related validity by…

Measuring individual differences in children's emerging language abilities is important to researchers and clinicians alike. The 2 most widely used methods for assessing children's vocabulary both have limitations: Experimenter-administered tests are time-consuming and expensive, and parent questionnaires have only been designed for children up to…

This study presents an independent replication and extension of psychometric evidence supporting the "Theory of Mind Inventory" ("ToMI"). Parents of 20 children with ASD (4; 1-6; 7 years; months) and 20 with typical development (3; 1-6; 5), rated their child's theory of mind abilities in everyday situations. Other parent report…

Universal screening of very early school-age children (age 4-7 years) is important for early identification of learning problems that may require enhanced learning opportunity. In this context, use of standardized instruments is critical to obtain valid, reliable, and comparable assessment outcomes. A wide variety of standardized instruments is…

Oral language skills are important to consider in school psychology practice, as they are directly tied to many areas of academic functioning. For example, research has demonstrated that oral language skills in early elementary school predict reading comprehension in later grades (Kendeou, van den Broek, White, & Lynch, 2009). With a…

Assessment of lexical/semantic knowledge is performed with a variety of tests varying in response requirements. The present study exemplifies the application of modern statistical approaches in the adaptation and assessment of the psychometric properties of the "Peabody Picture Vocabulary Test--Revised" (PPVT-R) Greek. Confirmatory…

The study investigated the concurrent validity of the Peabody Picture Vocabulary Test-Revised and Expressive One-Word Picture Vocabulary Test with the Wechsler Preschool and Primary Scale of Intelligence for 15 language delayed and 36 non-language delayed children (ages 45 to 76 months). (DB)

Three standardized language assessment measures (Peabody Picture Vocabulary Test-Revised, Test of Early Language Development, and the Preschool Language Scale) were individually administered to 25 nonreferred, White, middle-class preschoolers. Correlations among the three measures were statistically significant suggesting an interrelationship of…

Findings suggest that caution should be used in interpreting results of the Peabody Picture Vocabulary Test (PPVT) with preschool rural Black children. (Authors/CJ)

The results of the administration of the Preschool Language Scale to two succeeding classes of Head Start children (N 174) in a large, heterogeneous school district are reported. The scale is an individually administered instrument divided into receptive and expressive language areas. All children were administered the Preschool Language Scale,…

The Peabody Picture Vocabulary Test-Revised assesses standard American English receptive vocabulary in individuals, both handicapped and nonhandicapped, ages 2 to 40. This paper describes the test's administration, summation of data, standardization, reliability, and validity. (JDD)
