Although without a doubt discussed in professional circles for a long time before, the definition of mental disorder has been recently brought to the limelight by Trump narcissism debate:
“Everyone has a personality,” [Allen] Frances says. “It’s not wrong to have a personality; it’s not mentally ill to have a personality. It’s only a disorder when it causes extreme distress, suffering, and impairment.” [...]
Gartner — who has a PhD and treats patients in a private practice — wholeheartedly disagrees with Frances’s position. “The thing about people with personality disorders … they don’t have distress related to their disorder; they cause distress in other people,” he says. “They’re in complete denial about the nature of their illness or even having an illness.”
I'm not going to ask here what is your take on the controversy because that would be primarily opinion based. What I want to know is whether any surveys have been conducted of psychiatrists or psychologists on this issue, i.e. on where to draw the line with respect to harm/distress. Asking them this will not violate any ethics rules, I think. (I know where the DSM letter stands; for others' convenience here are links to DSM-IV's and DSM-5's version.)
