Post grad Specialization

Is there any way I can specialize in two, vastly different areas of psychology? preferably without doing loads of extra years' training? I am very interested in neuropsychology and in developmental / youth psychotherapy. To get into youth psychotherapy, the Doctorate programs are specific to children and adolescents, so I don't know if it's possible to do a post-doc QiCN after that?

The doctorates in Clinical Psychology (i assume you mean this) are not specialised. They are designed to give you a grounding across the lifespan and cover both formal assessments (intellectual, cognitive/neuropsy), therapeutic work and research. You wont be specialist in any area after qualifying, so yes you will need many additional years of trg and perhaps quaifications before you start to become more specialised.
I would also not focus on specific areas until you have done the doctorate, as your interests will most likely change during trg. A side note a Clinical Psy is rarely ever employed in a pure psychotherapy role (therapy makes up 1/3rd of my role and this is fairly standard).

hiya, yes I know that most are not specialized, but if you do a master's and doctorate at the Anna Freud Centre with the NHS, it's a doctorate that's specifically in child and adolescent Psychotherapy as far as I can tell from the course info, and you get offered specialized roles directly afterwards. let me know if I've misunderstood it, thank you.

That is a very different stream to Clinical Psychology (its not at all like the DClinPsy), so if you went down this route it is unlikely you would be able to do Clinical Neurospsychology as these are two very different careers not just different specialisations (this qualifies you as Psychotherapist only not a Practitioner Psychologist). You would have to do another doctorate afterwards (DClinpsy), as this course wont provide you the foundational knowledge you need for Clinical Neuropsychology.

thank you for the information. how is this particular degree different from a doctorate in counselling psychology? or is it the same thing? Just unsure as it says that entry to a QiCN requires a doctorate in either clinical or counselling psychology.
