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

An experimental study of the effects of autonomy support on preschoolers' self-regulation
TL;DR: In this article, a short-term experimental investigation of parent autonomy support and its effect on 3-year-old children's self-regulation was conducted, where parents were randomly assigned to complete a challenging puzzle with their child in either a highly autonomy supportive or highly controlling manner.

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.
