The World Psychiatric Association (WPA) Guideline on Schizophrenia Spectrum Disorders Management for Low- and Middle-Income Countries
Year: 2026
Type: article
Abstract: There is a pressing need to address the unique challenges of managing Schizophrenia Spectrum Disorders (SSD) in Low- and Middle-Income Countries (LMICs), where mental health resources are scarce and unevenly distributed. To develop this evidence-based guideline, we conducted a systematic review of the literature, followed by three rounds of Delphi surveys with experts from LMICs. The first two Delphi rounds identified and refined priority topics, while the third assessed their practical applicability in resource-limited contexts. The guideline emphasizes early intervention, continuity of care, and the integration of psychosocial interventions with pharmacological treatment, while explicitly tailoring recommendations to the realities of LMICs. Antipsychotic medications remain central, with second-generation agents recommended as first-line treatment for acute psychosis where available, but with recognition that first-generation agents are often the only accessible option. The guideline also discourages mega-dosing and unnecessary polypharmacy-common practices in some LMICs-in favor of rational monotherapy at the lowest effective dose. Psychosocial interventions are positioned as critical but are reframed for scalability: psychoeducation for patients and families, task-sharing to community health workers and trained lay providers, and reliance on peer support and faith-based networks where specialist services are lacking. The guideline stresses comprehensive care addressing physical, mental, and social needs, including vocational rehabilitation and housing support, while acknowledging barriers such as stigma, insecurity, and climate-related disruptions. Cultural adaptation is emphasized throughout, aligning interventions with local beliefs, social norms, and community structures to promote engagement, adherence, and sustainable outcomes.
