TLDR
In this paper, a method for combining results across independent-groups and repeated measures designs is described, and the conditions under which such an analysis is appropriate are discussed, and a meta-analysis procedure using design-specific estimates of sampling variance is described.Abstract:
When a meta-analysis on results from experimental studies is conducted, differences in the study design must be taken into consideration. A method for combining results across independent-groups and repeated measures designs is described, and the conditions under which such an analysis is appropriate are discussed. Combining results across designs requires that (a) all effect sizes be transformed into a common metric, (b) effect sizes from each design estimate the same treatment effect, and (c) meta-analysis procedures use design-specific estimates of sampling variance to reflect the precision of the effect size estimates.read more

Getting "game": pregaming changes during the first weeks of college
TL;DR: Pregaming rapidly escalates upon college entry and students who initiate in college may be at higher risk for alcohol-related problems, and campus prevention and intervention efforts should consider including pregaming in their prevention programming.

TL;DR: Empirical research highlights the positive effect of CR on patient HRQoL, and more RCTs and between-group studies employing pre-post designs should be conducted before clear conclusions can be drawn.

TL;DR: In this article, the authors present a model for estimating the effect size from a series of experiments using a fixed effect model and a general linear model, and combine these two models to estimate the effect magnitude.
