6Acceptance and Commitment Therapy (ACT)
ACT is a mindfulness-based behavioral therapy that has been proven effective with a diverse range of clinical conditions; depression, anxiety, substance abuse, OCD, perfectionism, workplace stress, chronic pain, PTSD, and even schizophrenia (Harris, 2006).
The goal of ACT is psychological flexibility, which is the ability to contact the present moment more fully as a conscious human being and to either change behavior or persist, when doing so serves valued ends (Wilson & Murrell, 2005). ACT helps people engage in behavior that is consistent with their values in spite of the difficult thoughts, feelings, memories, sensations, and urges that show up.
There are over 600 randomized controlled trials (RCTs) demonstrating the effectiveness of ACT across a wide range of human conditions.
