Functional Analytic Psychotherapy (FAP) has been making an important rise in Ibero-America in recent years. This paper presents a review of different contributions, problems and some proposals. Three principal topics are reviewed: (a) general characteristics and theoretical bases of FAP, (b) the uses of FAP and its relationship with other therapies, and (c) FAP's empirical research. A number of major papers were found on the first and second topic, but there were few articles related to the third theme. In general, authors in Ibero-America emphasize epistemological and conceptual aspects of FAP and its relationship with other interventions from Third Wave Behavior Therapies, especially Acceptance and Commitment Therapy (ACT). With regard to the third topic, FAP is an effective therapeutic perspective, but it is important to increase the research in this area. (Contains 1 footnote.)
