The overall mean effect size was dependent on the timing of cognitive assessment.
A significant mean effect size is found for total facial emotion perception (d = − 0.85).
The overall mean effect size of mentoring was significant, indicating that mentoring does improve career outcomes for individuals.
Overall, the analysis revealed a mean effect size of d = 0.30, indicating low to moderate intervention effects.
Patients with schizophrenia demonstrate impaired ability to perform corresponding control tasks, and the mean effect size is − 0.70.
A statistical meta-analysis integrates empirical studies, investigating the same outcome described as a mean effect size statistic.
Twenty-two experimetthemet the criteria for inclusion and demonstrated a moderate, negative mean effect size (g = −0.49, 95% CI −0.64 to −0.34, p < 0.001).
Results show that individuals with ASD spend less time attending to social stimuli than typically developing (TD) controls, with a mean effect size of 0.55.
Results showed that CRT produced an overall improvement on neurocognition (Mean effect size = 0.5), particularly in verbal and nonverbal memory, and executive function.
A random effects approach using inverse weights resulted in a mean effect size estimate of g = −0.33 (lower scores indicate less weight bias) for both attitudes and beliefs.
The individual effect sizes were then weighted, indicated by ES in this study, and an overall weighted mean effect size of the study pool was calculated.
