Does CBT help MS symptoms?

There has been a lot of comment on CBT's efficacy for MS since my first post. I'm going to throw this in the mix now: CBT emphasizes collaboration and active participation (Beck, 1995) and I wonder how that works with people who suffer from depression. Having struggled with depression myself, I know that the last thing I wanted to do when depressed, was to engage in the world and collaborate or participate in anything. I was therefore somewhat surprised to find that CBT is popular and effective in treating depression, even to the point of being a viable alternative to antidepressant medications. According to a study done in 2010, CBT has an enduring effect, which protects against relapses and recurrence when treatment has been concluded. The study found also that CBT might work to produce changes in cognition, which in turn cause or mediate changes in depression (Driessen, Hollon 2010). So perhaps easing the depression associated with MS would allow us to view our MS symptoms in a different light? Just wondering...
