Similar issue with the 'caregiver support' program ($2000 / month tax-free payments + health insurance coverage for stay-at-home spousal 'caregivers') for primary mental health disorders (PTSD, depression) in the VA system.
I can find no source in the respectable professional literature that it is standard of practice to recommend a monthly stipend (so that the spouse can stay home and 'care-give' to the patient suffering from depression or PTSD) as a 'treatment' or 'management' component for addressing these mental disorders.
Now, the VA is realizing that this was a bad idea (nobody is coming off of these programs) so they are--in certain geographical areas--'pulling people off' caregiver support programs, and there is the obvious public relations uproar (and newspaper articles).
They're also in a bind because the same rationale they used to place people onto the caregiver support program (to 'qualify' them for it)--namely, that they have a condition such as PTSD/depression as well as significant self-reported symptoms of same--well, guess what...they still report serious symptoms of PTSD/depression as well as functional impairment from said symptoms. This makes the 'decision' to pull them off the program appear (as it is) arbitrary at this point in time.
Whenever people ask me about it as a clinical psychologist I always reply that giving someone 2 grand tax free monthly payments is not a recognized 'treatment' or 'management' strategy (within my field) for addressing conditions such as depression or PTSD in adults.
