Meta-analysis is a method of synthesis of quantitative data from multiple independent studies addressing a common research question. An important part of this method involves computing a combined effect size across all of the studies.
Metapsychology (Greek: meta 'beyond, transcending', and ψυχολογία 'psychology') [2] is that aspect of a psychological theory that discusses the terms that are essential to it, but leaves aside or transcends the phenomena that the theory deals with.
A recent meta-analysis found significant improvements for positive symptoms and delusions, as well as the acceptance of the training. [7] These findings have been replicated in 2018 [8] and 2019.

In 2018–2020, a research topic in the journal Frontiers in Psychology highlighted the growing experimental, clinical, and neuropsychological evidence base for MCT. [20] A recent network meta-analysis indicated that MCT (and cognitive processing therapy) might be superior to other psychological treatments for PTSD. [21]
Qualitative psychological research findings are not arrived at by statistical or other quantitative procedures. Quantitative psychological research findings result from mathematical modeling and statistical estimation or statistical inference. The two types of research differ in the methods employed, rather than the topics they focus on.
Later meta-research identified widespread difficulty in replicating results in many scientific fields, including psychology and medicine. This problem was termed " the replication crisis ". Metascience has grown as a reaction to the replication crisis and to concerns about waste in research.
Meta-analysis is a method used to combine the results of different trials in order to obtain a quantitative synthesis. The size of individual clinical trials is often too small to detect treatment effects reliably. Meta-analysis increases the power of statistical analyses by pooling the results of all available trials.
