Purpose: People experiencing acute or severe psychosis in the United States do not typically have access to alternatives to standard practice. To provide people with psychotic symptoms meaningful choices in treatment, alternative approaches should be evaluated for potential integration
into the mental health service system. The need-adapted and open-dialogue approaches are psychotherapeutically focused interventions for psychosis that were developed in Finland. If these treatments are found to be effective, they could potentially be used in the United States. Method: This
narrative review uses systematic and transparent methods to locate and synthesize findings from treatment, quasi-treatment, and pretreatment outcome studies of the need-adapted and open-dialogue approaches. Results: One hundred twelve potentially relevant studies were identified for this review
using electronic searches and reference harvesting. Of those, 7 met the review's inclusion criteria. These studies revealed that the open-dialogue and need-adapted treatments had outcomes that were equivalent or superior to those of standard care. Discussion: More research is needed on these
promising modalities before they are routinely incorporated into U.S. practice.
