Calculating effect sizes for meta-analysis: The case of the single case∗
Open accessAbstract
This paper reviews methods for deriving measures of effect for interrupted time-series (single case) designs. Limitations of prior models are described. Modifications of a regression approach developed by Center, Skiba, and Casey (1985-86, Journal of Special Education, 19, 387-400) which can simultaneously account for treatment effects on level and slope while controlling for effects of trend are advocated and a step-by-step computational algorithm is provided. The primary modification entails computing the initial estimate of trend only on baseline data. Implementation of the method with various forms of single case designs is described.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
