ABSTRACT
ACT is based on the assumption that many forms of psychological distress and dysfunctional behaviour are underpinned by the same core processes (e.g. cognitive fusion and experiential avoidance). This theoretical assumption is supported by empirical demonstrations of ACT's ef®cacy across a wide range of human dif®culties. The broad applicability of the ACT model, along with its high level of technical ¯exibility, means that ACT can be applied in groups, and translated into brief training programmes for delivery outside of the traditional clinical arena (e.g. in occupational and educational settings; cf. Biglan, Hayes, & Pistorello, 2008).
