PSYCTC was a name I chose back in the early 1990s aiming to cover Psychology, Psychotherapy, Psychiatry, Counselling and Therapeutic Communities. It led, for a short time to psyctc.sghms.ac.uk, long ago the roots of www.psyctc.org.  I am creating this community to provide a more formalised and guaranteed persistent repository than www.psyctc.org for projects falling under these broad headings but now mostly PBE and psychometric work.  Much of the philosophy of the work here is given in my book with Jo-anne Carlyle Evans, C., & Carlyle, J. (2021). Outcome measures and evaluation in counselling and psychotherapy (1st ed.). SAGE Publishing. https://ombook.psyctc.org/book/
