You want to screen a patient with a significant mood disturbance for a distortion of the experience of time. Which single opening question is most appropriate?
The phenomenon's own eliciting notes recommend exactly this kind of open question as the first step. Questions about the date, current location, or a backward-counting task instead test orientation and concentration, which are related but genuinely separate from the subjective, felt pace of time that this phenomenon concerns.
Key discriminating feature: This is elicited with an open question about the felt pace of time, kept distinct from orientation questions (date, place), which test a different thing entirely.
