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

Behavioral Interventions Targeting Alcohol Use Among People Living with HIV/AIDS: A Systematic Review and Meta-Analysis.
Lori A. J. Scott-Sheldon,Lori A. J. Scott-Sheldon,Kate B. Carey,Blair T. Johnson,Michael P. Carey,Michael P. Carey +5 more
TL;DR: Results indicate that interventions reduced alcohol consumption, increased condom use, and improved medication adherence relative to controls, and show that behavioral interventions addressing alcohol use can successfully reduce alcohol consumption and also improve HIV-related outcomes among PLWHA.

From efficacy to effectiveness to broad implementation: Evolution of the Body Project.
Carolyn Black Becker,Eric Stice +1 more
TL;DR: The successful evolution of the BP from basic research to traversing the efficacy-to-effectiveness- to-dissemination/implementation continuum has yielded significant public health impact and is thus a fitting case for this special issue commemorating the 125th anniversary of the American Psychological Association.

Retest effects in cognitive ability tests: A meta-analysis
TL;DR: A comprehensive longitudinal multilevel meta-analysis revealed significant retest effects and no further score gains after the third test administration as mentioned in this paper, indicating that cognitive ability operation and content, equivalence of test forms, retest interval and participant age have a significant influence on the size of the retest effect.

A motivational hierarchy within: primacy of the individual self, relational self, or collective self?
Lowell Gaertner,Constantine Sedikides,Michelle A. Luke,Erin M. O'Mara,Jonatham Iuzzini,Lydia Eckstein Jackson,Huajian Cai,Quiping Wu +7 more
TL;DR: This article found a three-tiered hierarchy with the individual self at the top, followed by the relational self, and trailed at the bottom by the collective self in the human self.

Evidence for Cognitive Remediation Therapy in Young People with Anorexia Nervosa: Systematic Review and Meta-analysis of the Literature.
TL;DR: It is suggested that CRT has potential as a supplementary treatment for young people with anorexia nervosa, warranting further investigation using randomised treatment trials.

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.
