Among UHR patients, persistence or recurrence of non-psychotic comorbid mental disorders, mostly affective disorders, is associated with 6-year poor functional outcomes.

In people at UHR for psychosis, lifetime cannabis use was common but not related to outcome. Among cannabis users, frequent use, early-onset use and continued use after clinical presentation were associated with transition to psychosis.

Some qualified support was found for the relevance of early maternal bonding to later difficulties processing emotions. The presence of greater alexithymia in females, and female science students in particular, was discussed in reference to similar observations elsewhere. There was also an understandable relationship between 'difficulty identifying feelings' (TAS) and both depersonalization/derealization and absorption (DES).
