Our referrals come from a range of people but for Adult Mental Health it is usually the GP who has referred.
I work in some other services (learning disability and criminal justice) and there referrals come from social work, support providers and also other members of our teams.
We have a treatment time target of 18 weeks but most people wait more than this. There are various initiatives aimed at reducing this down but most still wait between 6 months and a year.
The number of clinical psychologists being trained is increasing - there are around 70 trained per year now whereas in the 90s it was only 20. But, with all the pressures on waiting lists and targets to see people lots of people are leaving to work privately so we have loads of unfilled posts.
I am not sure about the numbers for increases in referrals but I can only imagine that they have increased. When I first started work in the late 90's waits were only around 3 months max so the fact that now they can be up to 2 years suggests a massive increase in referrals not matched by increased training. There are now more nurse CBT therapists but not that many given how many nurses there are, although again they are all having trouble recruiting as well.
I know some people who work in England and their services are privatised so that they are now employed by companies that have contracts with the NHS. If this were to happen I can see even more people leaving to work privately and so the vicious circle continues.
