Published by the American Psychiatric Association (APA), the DSM-5 is the current classification system of psychiatric illnesses. This handbook serves "as a template to estimate the incidence (new cases) and prevalence (existing cases) of mental disorders in the general population."
235 entries, organized alphabetically, which include a general conceptual and methodological overview, a section on relevant assessment devices, and covering issues pertaining to methodology (validity, reliability, item response theory) and modes of assessment (tests, instruments and equipment for measuring behavioral operations).
The majority of articles in the PsycINFO database come from scholarly peer-reviewed journals, but you should still critically assess your sources to ensure that they have been peer-reviewed.
