Thank you for bringing up this great point - yes, agreed that patient-reported outcomes can be sometimes challenging even though this is the standard of "objective" measurement for mental healthcare! Part of our whole goal is to find additional objective measurements that don't need to rely solely on the patient's reporting. For example, how one uses their phone (have they left the house? are they socializing and in touch with others? etc.) could be telling. By combining different streams of information we can relieve patients, clinicians, researchers of just relying on the types of surveys you talk about to give a more objective view of the patient. We don't know of anyone else taking this comprehensive approach.
This is concerning for people suffering from disabilities and on long term medical leaves, and also where a private disability insurance provider (or even social security!) is paying the patient.
Most disability corps only care about maximizing revenue, and will look for any excuse (legal or not) to cut off a client. Often times they require full access to medical records, so what sort of information is in this records can be, for lack of a better term, life or death.
If a whether or not a patient left the house might be tracked and eventually accessed by an insurance agent, I would be extremely hesitant to use this product, and I know private disability insurance advisors that would be very afraid of this sort of thing, on behalf of their clients.
