We conducted a multi-pronged investigation of different types of reporting bias in autism early childhood intervention research. First, we investigated the prevalence of reporting failures of completed trials registered on clinicaltrials.gov, and found that only 7% of registered trials were updated with results on the registration platform and…

Advocates of bimodal bilingual (Bi-Bi) early intervention argue that both visual and auditory communication systems reflect optimal family and educational interactions for teachers, families, and their young children with hearing loss. The primary objective of this commentary is to highlight semantic variations noted in theoretical, ideological,…

In 2003, I began a doctoral research case study of the role of collaborative early intervention teachers as change agents implementing differentiated instruction in an intermediate school setting. Previous studies had focused largely on change theory in general, change in schools, early intervention programs, collaboration, or differentiated…

As a result of the 1998 reauthorization of Head Start, the Department of Health and Human Services conducted a national evaluation of the Head Start program. The goal of Head Start is to improve the school readiness skills of low-income children in the United States. There is a substantial body of experimental and correlational research that has…

This article describes four single-subject research designs comparing two or more interventions with young disabled children--the multitreatment design, alternating treatments design, adapted alternating treatments design, and parallel treatments design. Problems in using these designs include multitreatment interference, nonreversibility of some…

Three criticisms of family-centered models of early intervention for individuals with disabilities are put forth: the definition of family is indeterminate; early interventionists bring their own conceptions of the meaning of family to their work; and empirical research about family processes and their relationship to individuals' development is…

This article describes the multielement design, often recommended in single-subject research, and discusses its advantages and disadvantages for research in early intervention with handicapped children. The article concludes that the multielement design has many advantages, though multiple treatment interference is an issue of concern. (JDD)

This essay on EC 606 264, which found that more intense early intervention programs for children with disabilities were not more effective, comments on the "political incorrectness" of the results, the possibility for misinterpretation of the results, and the need to reexamine beliefs about what contributes to effective intervention programs. (JDD)

Critiques research findings on the effectiveness of the Early Intervention Project (EIP) for children with autism. The review finds sufficient threats to the experimental validity of the EIP to prevent unqualified endorsement of it as a validated treatment for children with autism. The review found in particular there were threats to external…

Refutes Gilliam et al.'s critique regarding the Comprehensive Child Development Program (CCDP) evaluation, including issues related to randomization, dropout rates, timing of evaluation, and services for control families. Discusses the broader issues regarding the appropriate interpretation of results of large-scale randomized trials of complex…

Reading Recovery (RR), an early intervention for first graders at risk of literacy failure, was introduced in Maine in school year 1990-91 and has been growing ever since. The Maine Department of Education has been funding the training of RR teachers since the 1994-95 school year. Although there is general agreement that the RR program is…

This article comments on results of a study (EC 629 869) on the reliability of the Modified Checklist for Autism in Toddlers (M-CHAT), a early detection screening test. It discusses concerns relating to clinic vs. population samples, data analysis, use of a parent questionnaire only to identify autism, and the age of screening. (Contains…

This article responds to comments (EC 629 869-70) on a study on the reliability of the Modified Checklist for Autism in Toddlers (M-CHAT), a early detection screening test. It addresses concerns relating to clinic vs. population samples, data analysis, use of a parent questionnaire only to identify autism, and the age of screening. (Contains 6…

This article reviews elements of a well-designed treatment study and evaluates the state of knowledge about comprehensive treatment programs for children with autism. Several suggestions are made for improving future studies, including more rigorous designs, searching for active ingredients of treatment programs, and measuring change. (Contains…

Discusses issues and challenges inherent in early research in the field of intervention and prevention of conduct disorders, including recruiting and working with parents who are stressed by the effects of poverty; designing appropriate interventions for young children; and using outcomes measures that reflect developmental continuities, subject…
