IPSS—Conclusions

Symptoms of schizophrenia are found around the world in many cultures

Profiles of schizophrenics look similar in different cultures

Profiles of schizophrenia look different than affective disorder

It is possible to conduct a multinational study with many collaborators

Heterogeneity as to onset, course, and outcome

Considerable chronicity—long term course is mostly stable, not progressive

Outcome: 33%– 33%–33%??

Extended prodrome and insidious onset

More benign course in non-modern settings
