This was needed elsewhere, so a quick important distinction:
From Greek:
• psychosis: mind-condition
• in psychosis: temporarily disconnected from reality
• psychopathy: mind-suffering or - disease
• a psychopath: a person with a persistent antisocial personality disorder
they’re unrelated
In terms of technical usage, whatever your discipline says it means is correct.
In terms of common usage, I'm afraid that ship has sailed, and 'psychopathy' means "the state of being a psychopath" as often as it has the technical meaning. 1/2
