Abstract
Since its introduction in 1972 by Jon Kabat-Zinn, Mindfulness Based Interventions (MBIs) have progressively become part of medical and mental health protocols, and many levels of society. Barker [1] points out that MBIs have become a popular and paradigmatic alternative healing practice and one of the frequently used tools from the toolbox of contemporary Mind-Body or Integrative medicine. Two of the most popular approaches, Mindfulness Based Stress Reduction ([MBSR], [2]) and acceptance and commitment therapy ([ACT], [3]) are the topics informing this article. In particular, this question is being asked: What makes MBSR and ACT so effective?
