Acceptance and Commitment Therapy (ACT) is an evidence-based psychological orientation whose effectiveness is proven by research in working with a variety of problems including anxiety, depression, schizophrenia, and drug use. ACT is grounded in a broader body of clinical science that points to the utility of mindfulness and values in positively influencing human well-being. ACT is a hybrid therapy, it combines various aspects of mindfulness, Gestalt therapy and humanistic-existential thought.

The paradox on which ACT is based goes as follows: radical acceptance of what cannot be changed gives us the power to recognize and change those things we are able to influence. The ACT approach thus involves accepting the necessary suffering so that we will be empowered to make more choices that will enable us to immerse in the process of living, that will allow us to embrace this life in a vital way, and that will enable us to live it in harmony with our deepest values.
