Transparency and replication are essential features of scientific inquiry, yet scientific communications of applied quantitative research are often lacking in much-needed procedural information. In an effort to promote researchers dissemination of their quantitative studies in a cohesive, detailed, and informative manner, the authors delineate…

This paper reacts to testimony on early childhood special education research before the President's Commission on Excellence in Special Education (EC 632 080). Noting the Commission's emphasis on accountability and results, it stresses the importance of being clear about desired outcomes, the need for sensitive and accurate ways of measuring…

This paper reacts to testimony on early childhood special education research before the President's Commission on Excellence in Special Education (EC 632 080). It notes the real technical and practical difficulties of developing valid assessments and research on the effectiveness of interventions. It urges greater attention to identifying…

This paper describes guidelines for reporting findings from studies using single subject methods, an approach from which early intervention has benefited substantially. Guidelines address: the foundations of the study, what was done to whom under what situations, what the data say, and what the findings mean. (Contains references.) (DB)

This response to an article evaluating Indiana's early intervention service delivery (EC 628 669) identifies implications of the study including: service intensity is relatively light; service location and context and the process of Individualized Family Service Plan formulation should be examined; implementation should be treated as an…

This paper addresses the conceptual issues of combining qualitative and quantitative methods in early intervention research by illustrating how two analytic approaches were used for different mixed-method purposes in the study of preschool inclusion. It describes practical strategies for conducting mixed-method data analysis in terms of data…

Ten French-speaking preschool children in Quebec with intellectual disabilities received either an intervention program based on the emergent literacy paradigm involving modeling, exploration, and interaction with an adult, or a comparison intervention. Pre- and post-test comparisons with a control group found the only item on which experimental…

This response to Rule et al. (EC 620 843) concerning translating research on naturalistic instruction into early-intervention practice with young children with disabilities raises concerns about treatment fidelity in such research studies, and notes the existence of pioneering models for studying treatment fidelity. (DB)

This response to Rule et al. (EC 620 843) concerning translating research on naturalistic instruction into early intervention practice with young children with disabilities questions whether the main features of naturalistic instruction are often fully implemented, and suggests that following the suggested guidelines might lead to actually…

Two experiments examined effects of play group composition (segregated or integrated), type of play materials, and group size (2 or 4 children) on language use of 24 preschool children with disabilities. Group composition and type of play materials had no significant effects. Group size had a significant multivariate effect on utterance rate and…

The Greenspan-Lieberman Observational System Revised was used to evaluate characteristics of dyadic interactions between 10 hearing mothers and hearing toddlers (HH), 10 deaf mothers and deaf toddlers (DD), and 10 hearing mothers and deaf toddlers (HD). Findings suggest that assessment instruments require some modifications and results must be…

Psychometric evaluation of the Preschool and Kindergarten Behavior Scales (PKBS) is reported. Factor analyses indicated the presence of a stable factor structure for both social skills and problem behaviors scales. Reliability studies indicated the PKBS has adequate-to-strong stability. Explorations of within-scale relationships yielded evidence…

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)

Eighty at-risk infants were administered the Mental and Motor Scales of the Bayley Scales of Infant Development at 6 and 12 months of age. Test-retest reliability scores of .71 on the Mental Scale and .69 on the Motor Scale were obtained. (Author/JDD)

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)
