The discussion on the possible inclusion of Attenuated Psychosis Syndrome as an offcial diagnosis of the DSM-5 was permeated by different values, which underpinned the division between those who argued in favor and those who were against the creation of that new category. The prominence given to certain values generated divergent positions, but which were equally legitimate and well grounded, and which brought up signifcant questions regarding the potentially innovative scenario of contemporary preventive psychiatry. The ethical preoccupation with suffering, the risks associated with preventive actions and the importance of the role of values in the formulation of diagnostic categories and in psychiatric practice were some of the key issues raised by that debate. © 2009 Associação Universitária de Pesquisa em Psicopatologia Fundamental/University Association for Research in Fundamental Psychopathology.181139151American Psychiatry Association, DSM-5 Development, , http://www.dsm5.org/Pages/Default.aspx, Recuperado em 21 mar. 2013 deAmminger, G.P., Long-Chain ω-3 Fatty Acids for Indicated Prevention of Psychotic Disorders – A Randomized, Placebo-Controlled Trial (2010) Archives of General Psychiatry, 67 (2), p. 146Banzato, C., Reifcation (2015) The Encyclopedia of Clinical Psychology, pp. 1-4. , In R.L.
