Implementing early intervention in psychosis in Indonesia: A scoping review

In order to prevent the immense burden and costs associated with psychotic disorders, (preventive) interventions in the early phase are considered a most promising strategy. Yet, their implementation faces particular challenges in low- and middle-income countries, where treatment gaps are greatest and resources are extremely limited. To exemplify these challenges, we conducted a scoping review of the relevant literature from Indonesia, a lower-middle-income Southeast-Asian country. We searched PubMed, CINAHL, Web of Science, PsycInfo, Garuda, and Repository UNAIR in titles and abstracts, using the following English search term and its equivalent in Bahasa Indonesia: (early OR risk OR prodromal) AND (psychosis OR schizophrenia OR psychotic) AND Indonesia. We included full papers on service delivery to first-episode psychosis (FEP) or clinical high-risk of psychosis (CHR), and on assessment of CHR in Indonesia. Seven papers, including one newspaper article, met our inclusion criteria. They showed a focus on economic, widely applicable risk assessments, mainly questionnaires or artificial intelligence-based algorithms, and brief interventions, particularly psychoeducation. Furthermore, our review exposed several areas that require further examination. In particular, Western diagnostic definitions of psychotic disorders and their early course need to be re-examined in the light of local health concepts and the role of the spiritual world. This re-examination is crucial for developing and prospectively validating culturally adapted definitions of CHR states and early intervention strategies for both CHR and FEP, with particular attention to the role of the (extended) family and spiritual, traditional healers, who are often the first point of contact.
