Hi Hawk,
Sorry for the late response - I haven't had comp access for a couple of days.
NLP is a useful tool in areas such as coaching, mentoring, work place management, personal development etc. but is not a tool that is used in the treatment of mental health.
As an indicator, it is not offered on the NHS anywhere.
Richard Bandler is not actually a clinical psychologist (in fact, I don't even think he is a psychologist) The difference between the two being about a further 6 years training and a doctorate!
A Psychologist cannot treat people for mental health issues however, they can perform reasearch task.
I have a couple of friends who are absolute Richard Bandler devotees and I can see that the motivational work and personal progression modules that he offers are very useful in their lives and have indeed helped them however, as a treatment for mental health then NLP should not be used.
Regards,
GS
