Abstract
Objective: The concept of duration of untreated psychosis or DUP has been a strong candidate for intervention as part of the early intervention paradigm. However, its importance has been questioned. This paper aims to present selected issues concerning attempts to reduce DUP and evaluate the impact of these attempts.
Method: Current research designs are critiqued and alternatives considered.
Results: Evidence suggests that it is difficult to design studies that are both ethical and potent enough to determine the contribution of treatment delay to outcome.
Conclusions: Further research is justified but this should not obstruct common-sense service reforms.
