What is ACT?
ACT (pronounced as one word) is an approach to psychological interventions defined in terms of certain theoretical processes and a philosophical framework, not a specific technology. In theoretical and process terms we can define ACT as a psychological intervention based on modern behavioural psychology, including Relational Frame Theory (RFT) that applies mindfulness and acceptance processes, and commitment and behaviour change processes, to the creation of psychological flexibility. Psychological flexibility means contacting the present moment fully as a conscious human being, and based on what the situation affords, changing or persisting in behaviour in the service of chosen values.
The general goal of ACT is to increase psychological flexibility. Psychological flexibility is established through six core ACT processes. Each of these areas are conceptualised as a positive psychological skill, not merely a method of avoiding psychopathology.
