The “Basic Training in Acceptance and Commitment Therapy and its Application in a Busy Clinic” Two-day Workshop organised by the Institute of Mental Health of Castle Peak Hospital was successfully held on 12-13 October, 2017, with nearly 100 health care professionals participated. We were honoured to invite Dr. Robyn WALSER, world-renowned clinical psychologist from the United States to deliver the workshop and to introduce basic concepts of Acceptance and Commitment Therapy (ACT). Through mindfulness exercises, experiential learning and experience sharing of the speaker, participants had a better understanding towards the application of ACT.
