This is a good question and one that I get asked quite frequently. I always encourage people to, if at all possible, complete the GLAD or PEAK programs in their suggested formats. Their validated results are based on the programs being completed as designed. Of course, unique circumtances may exist for patients and it is better to engage in something, rather then not engage at all. As a therapist, I have certainly seen that having an opportunity to supervise patients repeatedly on the fine details of these exercises is much different then meeting a couple of times and leaving patients with their home work list to manage on their own. This has been an eye-opener for me, even after 29 years of practice.
