Acceptance and Commitment Therapy (ACT) is a treatment package that combines several traditions such as early behaviourism, positive psychology and mindfulness. ACT is a trans-diagnostic model that has been successfully used to treat conditions such as depression, anxiety, PTSD, chronic pain, eating disorders and substance misuse just to name a few. ACT’s target is to promote psychological flexibility, that is, the ability to behave in a way that is consistent with one’s values even in the presence of aversive experiences (e.g. thoughts, feelings, physical pain). This is true as much for our clients as for the ACT practitioner. If you work in a context in which behaviour change is paramount, than this course will provide you with some very useful tools.
