Abstract
Early intervention programs for first-episode psychosis aim to intervene in the early stages of the disease. They are essential to prevent and delay the progression of the illness to a more advanced stage, but information about their characteristics is not systematized. The scoping review considered all studies of first-episode psychosis intervention programs, regardless of their context (hospital or community), and explored their characteristics. The scoping review was developed according to the Joanna Briggs Institute methodology and PRISMA-ScR guidelines. The PCC mnemonic (population, concept, and context) addressed research questions, the inclusion and exclusion criteria, and the search strategy. The scoping review sought to identify the literature that meets the predefined inclusion criteria. The research was conducted in the following databases: Web of Science Core Collection, MEDLINE, CINAHL Complete and PsycINFO, Scopus, Cochrane Library, and JBI Evidence Synthesis. The search for unpublished studies included OpenGrey (a European repository) and MedNar. It used sources in English, Portuguese, Spanish, and French. It included quantitative, qualitative, and multi-method/mixed methods studies. It also considered gray or unpublished literature. After removing duplicates, two independent reviewers extracted the relevant information after selecting the articles. If there were disagreements, a third reviewer was used. The researchers have developed a tool based on the JBI model that will allow them to extract the relevant information for the review. The results are presented schematically in narratives and tables. This scoping review maps first-episode psychosis intervention programs by identifying their characteristics, participants, and specific implementation contexts and allows researchers to create multicomponent programs tailored to different contexts.
