Right, what I meant to say was that to get trust, they have to believably and demonstrably commit and follow through with important changes. If it's at all in your power to make them know this (they seem to be resistant to information, although this could possibly signal a change, we aren't assuming anything), they must be brought to this realization. They cannot get trust merely by talking to us.
They must change, and change radically, or else there's no trust to be gotten. And I think this is what you're saying, too.
I'm not implying that you don't "get" this, just saying the obvious.
They should start with definition/name/cohort, adopting a biomedical view, and regular dialog with researchers and community. In this dialog, CDC most adopt the role of a learner (not their traditional role as teacher). Sorry for their government ego, but that's the honest truth. CDC knows next to nothing about this Disease or the people who live with it.
And, I know this isn't officially listed on the list of 9, but
it's closely related to definition and name: the ICD-10-CM. CDC is responsible for this and CDC must change it.
We don't want them getting any funding for research if it continues on current course, and we don't want them doing any physician education if they don't first make changes. We don't want them treating patients for stress-related fatigue or using a primary treatment strategy of CBT/GET and antidepressants. We would be better off without CDC involvement in any of those things if they don't first make believable radical changes.
