Divided into two volumes, "Handbook of Special Education Research" provides a comprehensive overview of critical issues in special education research. This first volume addresses key topics in theory, methods, and development, exploring how these three domains interconnect to build effective special education research. Each chapter…

Home interviews conducted with 102 families of children with developmental delays assessed ecocultural family resources, values, goals, and proactive adaptive efforts. Factor analyses on the ecocultural measures revealed 12 salient factors. Some factors were unique and statistically independent of traditional home environment measures. Significant…

Rasch calibration procedures were applied to item-response data for the 1,262 infants and toddlers comprising the standardization sample for the Mental Scale of the Bayley Scales of Infant Development. Analyses tend to confirm the psychometric integrity of the instrument. (Author)

The concurrent validity of the Battelle Developmental Inventory was explored by correlating Battelle results with scores from the Bayley Scales in 30 infants with known or suspected disabilities. Both the pattern and strength of the obtained correlations support use of the Battelle to measure development in infants with handicaps. (Author/JDD)

Developmental Record protocols were obtained from archival files for 1,069 institutionalized mentally retarded adults and children. Analyses revealed high internal reliabilities, but questionable validity. The Developmental Record did not adequately discriminate the five areas of functioning it purportedly assesses (self-care, perceptual-motor,…

This study, involving 67 children (ages 2 to 60 months) with motor delays, found that the Battelle Developmental Inventory (BDI) possessed moderate to high levels of concurrent validity with appropriate subtests from the Vineland Adaptive Behavior Scales and the Bayley Scales of Infant Development. (Author/JDD)

This paper describes two measurement integrity analyses conducted using data on the Battelle Developmental Inventory, obtained from a sample of 78 children with severe disabilities. Procedures used to conduct internal reliability and construct validity analyses are discussed. Researchers are urged to evaluate a test's construct validity when their…

Two studies investigated the developmental trends and concurrent validity of the Language Proficiency Profile-2 (LPP-2), a measure of language and communication skills for deaf children. Results indicate that the LPP-2 has good utility not only as a measure of overall language development but also as a predictor of achievement for English language…

This study first found that an adaptation of the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children exhibited construct validity and test-retest reliability in assessing preschool children's sensitivity to age-related differences in peers' developmental abilities. Second, children with disabilities were viewed as less…

Evaluation of the Kent Scoring Adaptation, which determines developmental ages in several domains based on an infant's performance on the Bayley Scales of Infant Development, with 27 at-risk infants supported the concurrent validity of the cognitive, language, and, to a degree, social domains of the Kent procedure but not the fine and gross motor…

When administered to 34 infants with handicaps, Bayley Scale mental age scores were an average of 2.1 months higher than Estimated Developmental Ages (EDA's) calculated from the Uzgiris and Hunt Scales. The EDA's were significantly and positively related to Bayley mental age, and sensorimotor play emerged as the best single correlate. (Author/JDD)

Thirty children (under 24 months of age) referred to an early intervention program were administered 3 developmental assessments. Although the Griffiths' Mental Development Scales correlated well with the Bayley Scales of Infant Development and the Battelle Developmental Inventory, the Griffiths' age equivalents were considerably higher than the…

The Infant Monitoring Project is designed to identify infants in need of further evaluation, by having parents complete a set of questionnaires about their infant's development at four-six month intervals. Evaluation of the questionnaires has shown that they are low-cost and have substantial agreement with standardized assessments. (Author/JDD)

The Psychoeducational Profile was translated into Chinese, adapted, and administered to 23 autistic children and 40 children with normal development, ages 3-7, in Hong Kong. The scale was found to have criterion-related validity, discriminant validity, and properties of a developmental scale. (Author/JDD)

The accuracy of 3 developmental screening tests administered to 89 young children was compared. The Battelle Developmental Inventory Screening Test was more accurate than the Academic Scale of the Developmental Profile-II and the Denver-II, identifying correctly 72% of children with difficulties and 76% of children without diagnoses.
