Este artigo tem o objetivo de realizar uma revisão histórica e conceitual da terapia de aceitação e compromisso (ACT). Esta é uma terapia cognitivo-comportamental baseada (a) no contextualismo funcional, filosofia que visa à predição e influência do comportamento com precisão, escopo e profundidade; e (b) na teoria dos quadros relacionais, uma abordagem pós-skinneriana da linguagem e da cognição. A ACT propõe um modelo de mudança do comportamento denominado flexibilidade psicológica, que explica o funcionamento saudável e psicopatológico por meio da interação de processos psicológicos normais. As evidências de efetividade e processo sinalizam que a ACT é um sistema terapêutico promissor, diretamente orientado para a identificação de mecanismos de mudança do comportamento humano.

This article (written in Brazilian Portuguese) discusses mindfulness as a concept that originated in Oriental meditative practices, became part of behavioral medicine starting with the Kabat-Zinn's stress reduction program and then spread out to office based psychological treatments. Its conceptual vicissitudes throughout this journey are reviewed and discussed. Implicit traces of mindfulness (like emotional tolerance and decentering) are argued to have been present in the clinical practices of traditional behavioral and cognitive therapies since their beginnings. Some clinical implications are discussed.
