Purpose: This systematic review and multilevel meta-analysis examines the accuracy of sentence repetition (SR) tasks in distinguishing between typically developing (TD) children and children with developmental language disorder (DLD). It explores variation in the way that SR tasks are administered and/or evaluated and examines whether variability…

Manipulation checks are an essential component of quality experimental design in motor learning. Guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework, this methodological systematic review examined the utilization of manipulation checks in focus of attention research. Seventy-eight protocols from four…

Research on anxiety and motivation in second language (L2) learning is proliferating. However, these two individual differences are commonly measured by self-report questionnaires, the psychometric properties of which have been questioned. Building on previous works on study quality, this methodological synthesis systematically describes and…

While there has been a lot of debate over the impact of online and remote learning on mental health and well-being, there has been no systematic syntheses or reviews of the research on this particular issue. In this paper, we review the research on the relationship between mental health/well-being and online or remote learning. Our review shows…

Developmental assessment scales are important tools for determining developmental delays and planning preventive interventions. One broad assessment scale used to evaluate child development is the Battelle Developmental Inventories (BDIs). The BDI-2 has a standardized version in English with good psychometric properties and a translated version in…

Structural equation modeling (SEM) is one of the most popular multivariate statistical techniques in Turkish educational research. This study elaborates the SEM procedures employed by 75 educational research articles which were published from 2010 to 2015 in Turkey. After documenting and coding 75 academic papers, categorical frequencies and…

When classifying the evidence base of practices, special education scholars typically appraise study quality to identify and exclude from consideration in their reviews unacceptable-quality studies that are likely biased and might bias review findings if included. However, study quality appraisals used in the process of identifying evidence-based…

Replications and robustness checks are key elements of the scientific method and a staple in many disciplines. However, leading journals in developmental psychology rarely include explicit replications of prior research conducted by different investigators, and few require authors to establish in their articles or online appendices that their key…

Background: This report continues in the lineage of reviews of research in educational leadership and management by examining methodological approaches used by doctoral researchers in studying principal instructional leadership. Research Design: The article reviews the full set of 130 doctoral dissertations completed over the past three decades…

Literature shows that most researchers are unaware of some of the characteristics of reliability. This paper clarifies some misconceptions by describing the procedures, benefits, and limitations of reliability generalization while using it to illustrate the nature of score reliability. Reliability generalization (RG) is a meta-analytic method…

Direct support persons (DSPs) often face problems in observing and determining alertness in individuals with profound intellectual and multiple disabilities (PIMD). A literature study was carried out to gather information about the problems just described. A search of two electronic databases and the references found in relevant hits revealed 42…

An error in an essential equation within the article by Williams and Zimmerman is corrected, and the algebraic inequalities are translated into questions a researcher can ask about simple or residualized difference scores. Williams and Zimmerman acknowledge the error and note that main conclusions are not affected. (SLD)

Reviews research on two measures of transference: Q-sort questionnaire measures and psychotherapy process measures. Q-sort, although reliable, lacks validity information. Psychotherapy process measures have reliability and validity. Considerable comparability was found between process measures and operationalized propositions from Freud's…

A review of alternative methodologies and a conceptual framework for the study of reliability of criterion-referenced tests are presented. The possibility of aptitude-x-assessment interactions is considered and implications are discussed. (Author)

Reviewed 149 studies which measured counselor or therapist competencies and examined them for evidence of the reliability and validity associated with the assessment instruments. Only 43 percent of the measurements included reliability data computed at the time they were used, and only 12 percent were accompanied by evidence of their validity.…
