Susie2310, the main reason I ever engage you is out of curiosity and some desire that you would participate in good faith to possibly consider of other points of view.
I made a second, even more careful attempt to review your original post. [I see you are now bowing out, but here it is anyway]:
1. In the first quote, you specify that, for the patient, the relationship is based on trust between them and the physician. In your opinion, does bi-directional trust come into play here, or is it only about whether the patient can trust the physician?
2. In the first quote, you state [the practice] isn't the best way [for the physician/provider] to begin a relationship based on [trust--from the patient's perspective]. In the second quote you add that you believe it is unethical. In your opinion, are there any ethical means by which a provider may attempt to ascertain the likelihood that a given prospective patient will engage in the relationship in good faith?
3. In the first quote, you state [the practice] isn't the best way to begin [a relationship based on trust]. What is the best way?
4. I feel that "intention of gaining psychological information" is an inappropriately broad (and thus disingenuous) way to characterize the action.
5. I'm not clear how you are you linking [the practice described in the OP] with your assertion that "the legal system with regard to bringing a suit against a physician favors the physician not the patient"? Does the ease or difficulty of bringing a malpractice lawsuit have something to do with whether or not the OP-described practice is ethical or not? Or were those two portions of your original comments unrelated?
6. This is a concern, I agree. I guess I just put it into a different context for myself personally: There are health data-collection related issues that concern me infinitely more than the thought of an individual small-time physician/provider who basically just wants to try to guess whether or not s/he and I will be able to get along and have a productive physician-patient relationship (which is what I think most of such screening is really about).
