CBT and BT: Some effect against chronic pain

Cognitive Behaviour Therapy (CBT) and Behaviour Therapy (BT) show some
effect in helping the disability associated with chronic pain, according
to a Cochrane Systematic Review. The researchers assessed the use of CBT
and BT on chronic pain, mood, and disability.

“For people with chronic pain, psychological therapies can reduce
depression and anxiety, disability, and in some cases pain, but guidance
is still required on the best type and duration of treatment,” says lead
researcher Christopher Eccleston, at the Centre for Pain Research at the
University of Bath.

Both CBT and BT try to manage pain by addressing the associated
psychological and practical processes. CBT involves the avoidance of
negative thoughts. BT helps patients to understand how they can change
their behaviour in order to reduce pain. Both approaches have been in
development for around 40 years and are sometimes recommended for
patients with long lasting, distressing pain that cannot be relieved by
conventional medicines.

In a systematic review, researchers considered the results of 40 trials
of CBT and BT, which included 4,781 patients in total. Patients
suffering from pain due to any cause, except headache, migraine, or
cancer, were included. Most studies were of CBT, which showed small
positive effects on pain, disability, and mood. There was less evidence
for BT, which the researchers say had no effect on disability or mood.

“Although there is overall promise for CBT in chronic pain, the term
covers a diverse range of treatment and assessment procedures. Right
now, we are not able to say which specific features of therapy may be
critical for improvement of a patient’s condition,” says Eccleston.

According to the researchers, simpler studies of CBT and BT that focus
on a purer form of treatment, rather than a variety of mixed methods,
would benefit the field.
