The intense clinical and research interest in early psychosis in recent yea
rs has highlighted a range of ethical issues which need to be considered ca
refully. Our perspective is based on 16 years of clinical and research expe
rience with young people at this phase of illness as well as the research c
ontributions of many others. We discuss the ethical dilemmas in relation to
the three key foci, which make up the early psychosis paradigm. These are
the pre-psychotic or prodromal phase, the period of untreated psychosis and
the first psychotic episode and the critical period of recovery, which fol
lows this. Most attention is devoted to the pre-psychotic period, however e
thical considerations related to research in the other two clinical foci ar
e briefly covered as well. Our contention is that the ethical issues are es
sentially identical to those arising in early intervention research in main
stream medicine. This has been concealed by inconsistency and emotion, whic
h has great potential to confuse, politicize and derail rational debate. Th
e legacy of the isolation of psychiatry from medicine and consequent prejud
ice and stigma in the professional as well as the public mind seems to be f
uelling a tendency in some societies to view psychiatric research as qualit
atively different from other medical research. Sound clinical research data
should be allowed to illuminate the options for potential consumers across
all phases of illness. The alternative is research paralysis, which would
force clinical practice to expand blindly without an evidence base. (C) 200
