Levels of evidence for the clinical efficacy and effectiveness of psychotherapies

Post by menojojo » Thu Apr 25, 2019 5:29 pm

I feel like I should be finding it easier to answer my own question but I'm feeling a little unsure about whether I'm looking for too much of a definitive answer.

Basically, I'm trying to find citable and succinct definitions for how government/professional bodies define and categorise the quality of the evidence (research studies) for the efficacy and/or effectiveness of psychotherapies.

To be a bit more specific, I found the Oxford Centre for Evidence-based Medicine – Levels of Evidence (https://www.cebm.net/2009/06/oxford-cen ... arch-2009/) which provides a chart outlining a hierarchy of evidence. The Australian National Health and Medical Research Council also have a levels of evidence similar to the Oxford one, see page six in this linked PDF https://www.mja.com.au/sites/default/fi ... 008-09.pdf

I have been reading through the NICE guidelines for certain psychological difficulties but feel that there isn't a definitive list of how certain types of studies are 'ranked' in terms of being the 'best' evidence for why certain psychotherapies are selected over others. For example this linked page outlines a lot of detail about how NICE guidance is developed https://www.nice.org.uk/process/pmg4/ch ... troduction, which is really great and thorough but I was trying to find a page where NICE have made a somewhat more succinct outline of their process of evaluating the evidence. Does such a page / outline exist for NICE?

Yes, NICE have a very structured methodology: https://www.nice.org.uk/process/pmg6/ch ... e-evidence
