Deontology of psychology in Argentina appears when the profession consolidates institutionally and academically, a process that culminates in the enactment of professional laws. In this context, the professional associations of the different provinces enacted their ethic's codes, and in 1999 the National Ethics Code from the Federation of Psychologist of the Argentine Republic (Fe.P.R.A.) arises as an attempt to unify deontological criteria. After 14 years, a review of the code was carried out taking into consideration the advancement of the psychological science and profession in this country, in consonance with the laws of protection and promotion of rights, enacted in the last decade. Thus, this paper aims to describe the fundamentals of the code's revision and emphasise the main changes on it. [ABSTRACT FROM AUTHOR]
