CBT for Chronic Pain + Insomnia Needs More Research

CBT for Chronic Pain and Insomnia Needs More Research – by Angie Drakulich – April 2018

The Sleep/No Sleep Pain Cycle

Most are familiar with the vicious cycle of insomnia, depression, and increased pain.

Finding the right mix of CBT—including patient education, self-regulation, behavioral activation, and cognitive reframing—may help to break this circle.  

Patient education is often the first step.

It’s also important for patients to distinguish between curative CBT for insomnia, which may involve a time-in-bed restriction, relaxation training, and bed re-association, for example, and sleep hygiene, which is preventive and may include steps such as avoiding stimulants, keeping the room dark, and sticking to a schedule.  

The Eye-Opening Research

While cognitive behavioral therapy for pain has been well validated and effective in improving patient outcomes (see Williams AC, et al’s 2012 Cochrane Database review and Qaseem A, et al.’s 2016 Ann Int Med review), it has been harder to demonstrate benefit in pain severity, especially when insomnia is involved.

I’m confused:

The author says, “CBT for pain has been well validated and effective in improving patient outcomes…”, and then goes on to say, “it has been harder to demonstrate benefit in pain severity, especially when insomnia is involved.”

So which is it?

Four studies examining a variety of pain conditions, combined with insomnia, found that sleep consistently improved with CBT therapy among chronic pain patients.

Pain outcomes did not improve, however, in terms of pain severity scale or pain interference measure

Well, surprise, surprise, pain severity didn’t improve with CBT.

Chronic pain patients have always known that but too many studies were set up in a biased fashion that made it look like it did.

These results were disappointing given the close association between pain and sleep, said Dr. Barwick. Why was there no shift in pain if sleep improved, she asked? Potentially because these studies targeted sleep rather than pain.

Another set of researchers attempted to target pain in patients with a variety of chronic conditions where insomnia was also involved.

The CBT studies showed improved sleep outcomes (less wake time, etc) but, again, on average, no improved pain outcomes.

That’s certainly been the truth for me. No amount or type of psychotherapy helped my pain severity, though it did help me learn to live with it.

But, I have to point out that this was not directly from “therapy”, but from getting support, sympathy, understanding, and encouragement which enabled my own monumental, more-or-less successful, efforts.

Toward a Resolution

So what does all this mean? Clearly, chronic pain, biopsychosocial elements, comorbidities, and individuals make for complex relationships, explained Dr. Barwick.

I don’t understand why they are still doing pain studies on mice if pain is such a complex bio-psycho-social construct. This would seem to indicate that no animal studies of pain can be applied to humans.

  • Why does CBT for sleep and pain improve sleep but not pain?
  • Is there a unique chronic pain-insomnia phenotype?
  • Do altered cognitive and affective regulation, activity level, or autonomic dysregulation severity play a role?

In conclusion, Dr. Barwick said hybrid therapies seem feasible and effective for sleep but not for pain.

An integrated protocol may be the best option for now, especially if it involves refined components and tested protocols in larger populations with longer-term follow-up.

    Here, I’ve got the solution: take the researchers and give each one a broken toe. Then measure their sleep parameters with and without CBT. In the second arm of the study, (crossover design), give half of them a digital nerve block before bed so the pain is controlled (no drug effects). No relief for the other half, sorry. Measure sleep parameters. Big revelation I’m sure….

      Oh boy, if our imaginations ever became real, all those know-it-all docs, politicians, insurance execs, DEA agents, etc. would suddenly have incredibly unbearable pain problems from all the patients they stiffed on pain relief wishing them a taste of their pain.

    I agree with totally what you said about the psychology therapy aspect not reducing or alleviating pain in any way, but perhaps just helping manage it a little better, that’s been my experience also. An interesting article as this field definitely needs more research but, I feel, more ‘real world applicable’ studies. x

      Indeed, I could use more psychological help for dealing with my pain.

      Sadly, most psychologists don’t “get it” either. I went to one who insisted I was “creating my own pain so I’d feel justified in taking opioids”.

      Good grief, the crazy things the recovery industry tries to propose!
