2. Another of the therapies is dialectical-behavioral that has indicated effectiveness in treating many problems: anxiety, depression, bipolar disorder, ADHD or substance abuse.
3. Metacognitive therapy based on the fact that it is not the content of thoughts that perpetuates mental disorders, but the presence of what is called attentional cognitive syndrome.
4. Behavioral activation therapy is one of those that have shown greater efficacy in the treatment of depression.
