This article aims at problematizing the ways through which Psychology articulates with the collective health field. We have employed a genealogical strategy, using Foucauldian analysis tools, such as bio-power, truth, and subjectivity. This study is a reflection on modifications of psychological practices produced when the psychological fact is no longer an organism domain, becoming an effect of the subjects' life history. Such change concerns the approximation of psychological practices to the field of public health policies. This approximation is understood as a battlefield in which both individualizing logic and the logic of health militancy operate; the former is present when psychological practices fit public policies into a technical, tutelary, private rationality, and the latter is produced through conformity of psychological practices to both right and citizenship.
