Combining effect size estimates in meta-analysis with repeated measures and independent-groups designs.
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

Developmental effects influencing observational modelling: A meta-analysis
TL;DR: In this paper, a meta-analysis was conducted on the observational modelling literature to quantify overall between-participant treatment effects (δ u Bi) gained for child and adult populations.

Sequential Stereotype Priming: A Meta-Analysis.
TL;DR: A meta-analysis of stereotypes priming revealed that stereotype priming is significantly moderated by the presence of prime–response relations, participant task, stereotype dimension, target stimulus type, SOA, and prime repetition.

TL;DR: Six months of aerobic exercise in healthy, sedentary older adults was not associated with improvements in FA or MD measures of cerebral WM microstructure, as defined by increased fractional anisotropy and/or decreased mean diffusivity after the aerobic exercise intervention.

TL;DR: Brief admission does not seem to be more effective than treatment as usual in reducing the use of inpatient services in individuals who self-harm and are at risk of suicide.

Sleep-Disordered Breathing Impact on Efficacy of Prolonged Exposure Therapy for Posttraumatic Stress Disorder.
TL;DR: These observations supported the hypothesis that the efficacy of PE therapy is affected by sleep quality, and treatment algorithms may need to incorporate the presence or absence of sleep disorders as a factor in treatment choice.

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.
