Evidence for this tapping therapy - EFT (Emotional freedom technique) I just heard or maybe I saw a clip on tv about this tapping technique. Something about tapping various points of the body for psychological treatment. 

What is this EFT all about? Is there any solid evidence for EFT? 


Discussed in this Skeptic thread too, sorry I didn't realise it was there - https://skeptics.stackexchange.com/questions/231/what-is-eft-emotional-freedom-technique-and-does-it-work
Emotional Freedom Technique (EFT) is part of the energy psychology movement which draws on various forms of alternative medicine to stimulate meridian points of the body (Gaudiano, 2000). At the moment it is considered pseudoscience because it has no effect beyond the placebo-effect in clinical psychology (Bakker, 2013).

This is an excerpt from a study by Waite &amp; Holder (2003) that assessed the effectiveness of EFT for anxiety:


  These results do not support the idea that the purported benefits of EFT are uniquely dependent on the "tapping of meridians." Rather, these results suggest that the reported effectiveness of EFT is attributable to characteristics it shares with more traditional therapies.


And here is the abstract from another article by Bakker (2013) on energy psychology, the "field" EFT falls in:


  Proponents of energy psychology techniques, such as Thought Field Therapy and Emotional Freedom Techniques, have sought “empirically supported therapy” status despite an unsupported and implausible theoretical basis and claims in response of representing a “pseudoscientific” movement. Two major reviews of the supportive evidence which has accumulated over the past 30 years have been published recently. This current status report describes the history, theory, techniques, claims, and implications of the energy psychology movement, examines support for its theoretical base, its current outcome study support, and offers conclusions and recommendations as to its research and clinical prospects. It is concluded that there is scant support for the radical theories underlying energy psychology techniques, and that empirical support for their efficacy is methodologically weak, and has not been able to demonstrate an effect beyond nonspecific or placebo effects, or the incorporation of known‐effective elements. The only dismantling studies to date have been disconfirmatory. Further research is highly unlikely to be scientifically productive, and scientist practitioners are advised to continue to adhere to well‐established cognitive and behavioural principles.


So, overall there is little scientific evidence for the underlying assumptions of EFT, hope this answers your question!
