Psychosocial Treatment for First-Episode Psychosis: A Research Update
Abstract
OBJECTIVE: This article reviews research on psychosocial treatment for first-episode psychosis. METHOD: PsycINFO and MEDLINE were systematically searched for studies that evaluated psychosocial interventions for first-episode psychosis. RESULTS: Comprehensive (i.e., multielement) treatment approaches show promise in reducing symptoms and hospital readmissions, as well as improving functional outcomes, although few rigorously controlled trials have been conducted. Individual cognitive behavior therapy has shown modest efficacy in reducing symptoms, assisting individuals in adjusting to their illness, and improving subjective quality of life, but it has shown minimal efficacy in reducing relapse. Some controlled research supports the benefits of family interventions, while less controlled research has evaluated group interventions. CONCLUSIONS: Adjunctive psychosocial interventions early in psychosis may be beneficial across a variety of domains and can assist with symptomatic and functional recovery. More randomized, controlled trials are needed to evaluate the effectiveness of these interventions, particularly for multielement, group, and family treatments.

“In addition, naturalistic studies of psychological treatments for a variety of nonpsychotic disorders have demonstrated that patients tend to show greater degrees of improvement with longer periods of treatment (100).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
