I'm in a CBT (one on one) program but the therapist borrows frequently from the DBT toolbox. I'm nearing the end of the 12wk course and I must say it has been very positive. I have developed a number of strategies that soothe and help me better manage my anxieties, low self esteem, and depression. I highly recommend it.

This is MY understanding of the difference between the two:
- CBT is more about challenging Negative Core Beliefs and developing coping skills to manage anxiety and depression
- DBT additionally teaches Mindfullness as a coping and management skill. It also challenges one's behavioural responses.
