An editorial notes that although ω-3 PUFA treatment is attractive for prevention from a pathophysiologic perspective and because of its benign adverse effect profile, its preventive efficacy for psychosis had been demonstrated in only 1 single-site study (n= 81); the results of which have not been confirmed in this current study. Two additional multisite studies of ω-3 PUFAs are underway to further clarify its role in the prevention of psychosis.
