What is it?

Dialectical Behaviour Therapy (DBT) is a type of psychological treatment. DBT was originally developed to treat other psychological disorders but can also be used to treat depression. DBT is similar to cognitive behavioural therapy (see more on cognitive behaviour therapy) and also includes mindfulness strategies. DBT involves both individual sessions with a therapist and group therapy sessions.

How does it work?

DBT teaches people a number of skills to help cope with difficulties they face. These skills include mindfulness (being aware of situations or thoughts without judgement), impulse control, interpersonal skills, and how to manage emotions and cope with feeling distressed. Improving these skills allows people to better cope with everyday life events in an effective and positive way. 

Is it effective?

There is very little scientific evidence on DBT for the treatment of depression. More studies of better quality are needed.

Two small studies found that both adults and older adults who were treated with DBT and antidepressant medication showed more improvement in their depression symptoms compared to those who simply took antidepressant medication. In one study these positive effects lasted for six months after treatment.

There is no evidence of the effectiveness of DBT in adolescents and children.

Are there any disadvantages?

DBT may involve seeing a therapist weekly for several months which can be expensive. In Australia Medicare provides rebates for visits to trained therapists (see below).

Where do you get it?

DBT is generally provided by therapists such as clinical psychologists, psychologists or counsellors who have been specially trained to provide this therapy (see Psychologists and other therapists). In Australia, Medicare provides rebates for visits to some therapists under the Better Access to Mental Health Care scheme. DBT may also be covered by some private health insurance funds.


DBT is a promising alternative to other psychological therapies but more evidence is needed to be sure it works. It may be combined with antidepressant medication to treat depression.
