Small but important differences in effectiveness of various
psychological interventions for symptoms of psychosis emerged in a metanalysis,
“Psychological Interventions for Psychosis: A Meta-Analysis of Comparative
Outcome Studies,” in AJP in Advance (February 18, 2014).
Dutch researchers analyzed forty-eight outcome trials comparing psychological interventions for psychosis. The comparisons included 3,295 participants. Categorization of interventions resulted in six interventions being compared against other interventions pooled: Cognitive behavior therapy (CBT), supportive counselling, social skills training, psychoeducation, cognitive remediation and befriending. Separate sub-meta-analyses for positive, negative, or general symptoms were undertaken when there were sufficient studies assessing these outcomes.
