It is important to establish a concrete period of time when evaluating a patient's previous depressive episode. What are the exceptions to this rule?

If there was an episode in the last year, the clinician should ask about it first, even if it was not the worst.
When there are several possible episodes to choose from, it is advisable to prioritize those that occurred during periods when the patient was not using substances/medications known to cause depression and was not suffering from a potentially etiological CMG.
If the patient reports more than one previous episode, the clinician should establish which episode was the worst, and subsequent questions should focus on the worst period of two weeks during that 'worst' episode.

b) II and III are correct.
