Implications of the current analysis for future practice and research in the area of parent tutoring are discussed. In: Journal of Behavioral Education, Vol. Certain treatment characteristics appeared to moderate outcome. Do Functional Behavioral Assessments Improve Intervention Effectiveness for Students Diagnosed with ADHD A Single-Subject Meta-Analysis. Most studies involved reading and the use of primary grade students as subjects.
A mean weighted ES of +0.55 was obtained for trimmed group design studies and a median PND of 94 was obtained for the single subject studies. Effect size (ES) and PND were generally positive across both types of studies.
Comprehensive meta analysis single subject series#
Separate analyses were conducted for group design and single-subject design studies using standardized mean difference between experimental and control groups, and percentage of non-overlapping data (PND), respectively. Presentations William Shadish: Meta-Analysis of Single Subject Designs: An Overview Natasha Beretvas: Effect Sizes for Meta-Analysis of Single Subject Designs Eden Nagler: Analyzing Data from Small N Designs using Multilevel Models Single Subject Designs (SSDs) A time series of observations on one person. (Single-Case Meta-Analysis) Calculate effect size Combine p-values What follows will illustrate the functionality of the package with an example from ter Kuile et al. Thirty-two comparisons were found for 20 group design studies and 25 comparisons were found for 17 single subject design studies. single-subject designs were more prevalent than group designs. criterion-referenced or norm-referenced), and whether or not the study was published. The effectiveness of parent tutoring in 37 studies was examined across grade level, basic skill area (e.g., reading, math), training feature (e.g., treatment length, availability of consultation), treatment fidelity, type of assessment (i.e.
The current review extends this earlier work by conducting a meta-analysis of single subject design writing intervention studies. Statistical significance was set at a two-sided P <. We evaluated the pooled data for meta-analysis with a random-effects model.
Perin, 2007a) addressed this issue by identifying effective instructional writing practices. The test for subgroup difference in two-arm meta-analysis and the test for total between-groups heterogeneity in single-arm meta-analysis were performed to examine differences among subgroups. This article provides a synthesis of research in which parents provided academic instruction to their own children. A recent meta-analysis of true- and quasi-experimental writing intervention research (S.
