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

Meta-analysis of patient education interventions to increase physical activity among chronically ill adults.
TL;DR: It is suggested that some patient education interventions to increase physical activity (PA) are effective, despite considerable heterogeneity in the magnitude of intervention effect.

Exercise Interventions for Cancer Survivors: A Meta-Analysis of Quality of Life Outcomes
TL;DR: Overall, exercise interventions increased QOL, but this tendency depended to some extent on exercise and patient features, and models revealed that interventions were particularly successful if they targeted more intense aerobic exercise and addressed women.

Attentional Bias for Positive Emotional Stimuli: A Meta-Analytic Investigation
TL;DR: A meta-analysis systematically compared attentional bias for positive compared with neutral visual stimuli across 243 studies that used different types of attentional paradigms and positive stimuli, suggesting that attentional biased for positive stimuli occurs rapidly and involuntarily.

Mindfulness Training Affects Attention—Or Is It Attentional Effort?
TL;DR: It is argued that MBSR may contribute uniquely to attentional improvements but that further research focusing on non-reaction-time-based measures and outcomes less confounded by test effort is needed.

The effectiveness of treatment for pediatric obsessive-compulsive disorder : A meta-analysis
TL;DR: Results showed that pharmacotherapy with serotonergic antidepressants and cognitive-behavioral therapy involving exposure and response prevention are each effective in reducing OCD symptoms.

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.
