If the UCLA program is very cutting edge, you can even expect to find one or more of the "Alphabet Therapies" – EMDR, EFT, SE or PET, to name a few, along with the other tools. These are imagery-based, short-term methods that can be very helpful in alleviating some of your wife's symptoms.
The truth is, any sort of mind-body self-regulation tool – guided imagery, meditation, breathwork, self-hypnosis – is going to help your wife manage and contain her anxiety, and this will help her to modulate her OCD as well.
The best approach is multi-modal, using many of these methods, and attacking the condition from many angles. Unless something extraordinary happens, it's safe to say that you can expect to see some improvement in the near future, and it should continue to get better over time. It's possible your wife will be quite improved, and maybe even symptom free.
So good for both of you. Stay with it. We also have some guided imagery specifically designed for OCD, that's named, not surprisingly, Help for Obsessive Compulsive Disorder. She may want to add that to her toolkit.
Again, expect change to be incremental. She just needs to listen regularly – once or twice a day is fine – for a few weeks. It doesn't matter if she falls asleep while she's listening. It will still sink in.
Now, I'm not sure what brought you to the point of seeking help after all these years – something must have changed – but it makes me want to offer one warning: her improvement will create some major changes in your relationship if she's been suffering from this for 60 years.
You are to be commended for being such a supportive and involved spouse, but it's possible that some phases of her treatment might require you to step back and let her do some heavy lifting without your guidance. Your job will be to step back and adjust to the changes – a significant challenge in and of itself. Even if the changes are long hoped for, positive ones, they will still take some getting used to!
My best wishes to you both.
