This paper aims to analyze the influence of positivist paradigm in nursing. This thought tendency is described in terms of history and characteristics and nursing view under the reactive or particular - deterministic vision. Afterwards, it deepens over some positivism elements which are present in nursing area, such as: sanitary assistance, training nurses, and research care management. It is concluded that being able to visualize named areas under a holistic view, which is given by other paradigms as well as the observation of benefits comprehensively and transpersonal care by users, health team and society, a change in the value placed on nursing discipline can be reached. © 2013 Fundació Index.
