What is the most effective intervention for reducing/preventing psychotic symptoms and improving social functioning in people at risk of developing first episode psychosis
There is some very limited evidence, from one generally well
conducted systematic review, that cognitive behavioural therapy
(CBT), integrated psychotherapy, pharmacotherapy (olanzapine), and
dietary supplementation (omega 3 fatty acids) may be associated
with reduced rates of transition to psychosis. However, as noted by
the review authors, data were sparse and of limited quality; most
comparisons were reported by a single study and analyses frequently
included only those participants who completed the study.
Further research is needed to adequately assess the
effectiveness of interventions for the treatment of people at high
risk of psychosis.
