Dialectical Behavior Therapy (DBT)
is a form of cognitive behaviour therapy. It was the brainchild of Marsha M.
Linehan. Linehan’s experience of treating individuals with borderline
personality disorders formed the basis of her efforts to develop this
therapeutic approach.
It is important to understand the word dialectics to understand the core
essence of this therapeutic approach. Dialects refer to the essential idea
that each statement of a position (thesis) contains an opposing position with
its own self (antithesis).
In the DBT framework dialectics highlights two assumptions; a client is
functioning to the best of their abilities but also needs to change and the
root cause of all their issues may be external to them, but they have to take
the responsibility of resolving them.
Thus, this approach helps clients deal with their limitations and focus on
their potential for change.
The main components of DBT are:
-
Problem-Solving: Under this paradigm, DBT applies
behavioural principles and assessments based on cognitive behaviour
therapy. For example, cognitive restructuring focuses on dealing with
maladaptive thought patterns. After identifying problem behaviours, the
therapist and client collectively conduct an in-depth review of the issues
at hand and the situational factors surrounding them. This is followed by
a discussion of the application of alternative responses for improved
problem-solving.
-
Validation: Validation is the process of providing a
supportive base to the client’s thoughts and feelings by providing
feedback and reinforcement. This process is considered a helpful method of
bolstering self-validation and therapeutic alliance.
-
Skills Training: This mode of treatment is included in
DBT in order to assist clients in improving their capabilities to live
better lives. It includes the following:
-
Emotional regulation: Includes cognitive and behavioural
strategies for dealing with maladaptive emotional responses.
-
Distress tolerance: Aims at training clients in impulse
control and developing functional ways to deal with crisis situations.
-
Mindfulness skills: Includes attending to awareness of
surroundings, being non-judgemental in disposition, focusing on the
present context, etc. This training helps clients to develop effective
ways of living their lives.
-
Interpersonal effectiveness: Focuses on teaching
assertiveness skills. In addition, building interpersonal skills assist in
maintaining relationship priorities and demands along with strengthening
self-respect.
Core strategies applied in the DBT framework are as follows:
-
Behavioural Analysis: This is a joint effort between the
therapist and client to identify units of behaviour forming the basis of
problem behaviour. A chain analysis is conducted starting from the
antecedents, to the final consequences of the behaviour. The aim of this
analysis is to uncover maladaptive elements that result in emotional
dysregulation.
-
Solution Analysis: The results of the behavioural
analysis are further applied by attempting to identify the client’s goals,
needs and desires. The client is assisted in finding alternative solutions
to their problems.
-
Problem-Solving: Contingency procedures in DBT focus on
removing elements that reinforce non-constructive behaviour. For example,
acts of self-injury are often reinforced by the attention and care that
follow from the family. DBT sessions also help clients develop useful
behavioural skills that are then strengthened during sessions gradually.
Evidence Base
DBT as a therapeutic approach has been the most effective module applied to
the treatment of borderline personality disorder. DBT has also garnered strong
empirical support in reducing suicidal behaviour in clients with BPD and other
disorders.
In addition, self-injurious behaviours can also be addressed under DBT. DBT
has also been found useful in the management of eating disorders, substance
use and depression
