jones_supa writes "British Psychological Society's division of clinical psychology (DCP) will on Monday issue a statement declaring that, given the lack of evidence, it is time for a 'paradigm shift' in how the issues of mental health are understood. According to their claim, there is no scientific evidence that psychiatric diagnoses such as schizophrenia and bipolar disorder are valid or useful. The statement effectively casts doubt on psychiatry's predominantly biomedical model of mental distress – the idea that people are suffering from illnesses that are treatable by doctors using drugs. The DCP said its decision to speak out 'reflects fundamental concerns about the development, personal impact and core assumptions of the (diagnosis) systems', used by psychiatry. The provocative statement by the DCP has been timed to come out shortly before the release of DSM-5, the fifth edition of the American Psychiatry Association's Diagnostic and Statistical Manual of Mental Disorders. The manual has been attacked for expanding the range of mental health issues that are classified as disorders."
