This paper aims to discuss psychologists' technical-assistencial and political forms of participation facing Mental Health Policy. Its analysis plan was to take Piauí's reality to analyze the Brazilian picture. For that, it were outlined three stages: documentary research to identify the psychologists participation in local psychiatric reform process; semistructured interviews with psychologists (n = 33); monitoring, through participant observation and conversation circles, of contexts/sociopolitical reformists events occurred in the biennium 2009/2010. Results have shown that, despite social commitment speeches and engagement of the category in defense of psychiatric reform in national plan, these actions have little equivalence as transformation of practices and political-professional postures in everyday services. By being involved with the preservation of the classic modus operandi of being psychologist, is understood that psychologists participation gives little technicalassistencial and sociopolitical sustainability to the anti-asylums fight.
