Complex survey data are collected by means other than simple random samples. This creates two analytical issues: nonindependence and unequal selection probability. Failing to address these issues results in underestimated standard errors and biased parameter estimates. Using data from the nationally representative Head Start Family and Child…

The purpose of this study was to determine (a) if the reading program adopted by Sally D. Meadows enhanced the achievement of students placed in the Early Intervention Program (EIP); (b) if the students' reading achievement scores increased more after the second year of implementation than they did after the first year of implementation; and (c)…

Second-generation early intervention research typically involves the specification of multivariate relations between interventions, outcomes, and other variables. Moderation and mediation involve variables or sets of variables that influence relations between interventions and outcomes. Following the framework of Baron and Kenny's (1986) seminal…

Assessment within the fields of early childhood education and early childhood intervention is guided by the "deductive-psychometric model", which is a framework for legitimizing constructs that arise from theories. An alternative approach, termed the "inductive-experimental model", places significantly more restrictions on what constitutes a…

Detecting early signs of autism is essential for timely diagnosis and initiation of effective interventions. Several research groups have initiated prospective studies of high-risk populations including infant siblings, to systematically collect data on early signs within a longitudinal design. Despite the potential advantages of prospective…

An evaluation tool, the Evaluation Center Cube (ECC), is presented as a vehicle for establishing an analytic framework and uniting evaluation strategies. The ECC was developed in response to the Kellogg Foundation's need to categorize community-initiated funding proposals. As a classification tool, it facilitates proposal analysis and is…

Describes Q methodology, a technique that can be used to gain important insights on individuals' judgments, attitudes, and points of view on topics or situations that involve early intervention effectiveness issues. Specific steps involved in Q methodology are illustrated in a description of an early intervention efficacy study. (Author/CR)

In early intervention, researchers often are interested in interpretation aids that can help determine the relative importance of variables when multiple regression models are used, and that facilitate deeper insight into prediction dynamics. Commonality analysis is one approach for helping researchers understand the contributions independent or…

With its roots in clinical and educational psychology, school psychology is an ever-changing field that encompasses a diversity of topics. "The Oxford Handbook of School Psychology" synthesizes the most vital and relevant literature in all of these areas, producing a state-of-the-art, authoritative resource for practitioners,…

This paper reviews analytic methods for estimating growth curves or developmental trajectories from longitudinal data. Traditional models for studying change are contrasted with a relatively new method, hierarchical linear models. Evidence is presented indicating that hierarchical linear models can overcome some of the methodological limitations…

Reviews three areas of limitations in the comparative evaluations of early intervention alternatives for disabled children presented in this volume: (1) inaccurate outcomes measures; (2) a misconception of parent training programs as representing true family involvement; (3) and the lack of control over the integrity of treatment given study…
