This title is not properly put together. What should be the first part (30 min) is actually a 30 minute condensed version of the entire 3 part program. Parts 2 and 3 are each correct. To get the whole program you may need to purchase parts 1,2 & 3 separately.
That said, this is an interesting listen, though it does not provide much insight psychoses. Listeners might also be interested in the audible title 'The Center Cannot Hold' by Elyn Saks, which provides chilling insight into the nature and experience of psychosis in the words of one who has ample experience of it.
