Adapting the First Episode Psychosis Services Fidelity Scale in Asia: A Comprehensive Evaluation of Singapore's Early Psychosis Intervention Programme.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFidelity assessments are crucial for ensuring evidence-based delivery of first episode psychosis (FEP) services. The First Episode Psychosis Services Fidelity Scale (FEPS-FS) is a validated tool for evaluating FEP programmes, but its application in Asian contexts remains unexplored. This study applies and adapts the FEPS-FS to evaluate Singapore's Early Psychosis Intervention Programme (EPIP) in 2024, examining its contextual applicability within Singapore's healthcare framework.
methodsFidelity was assessed at EPIP through programme data analysis, health record reviews, and interviews with staff, patients, and families. Three evaluators scored 37 items on a five-point scale, with ratings determined by consensus. Two items were selectively added from an earlier FEPS-FS version to address local contexts. Items rated ≤ 3 indicated areas needing attention. The FRAME methodology documented adaptations for local challenges, particularly in weight management and substance use interventions.
resultsEPIP demonstrated high fidelity to evidence-based FEP practices, particularly in programme structure and clinical processes. Twenty items achieved maximum ratings, including team integration, family engagement, and clozapine adherence. Lower ratings (≤ 3) identified gaps in participant ratios, psychiatrist caseload, and medication practices. Five items, primarily related to psychological and occupational therapies and substance use interventions, were unscored due to documentation differences, highlighting the need for tailored adaptations.
conclusionThis study demonstrates EPIP's strong adherence to evidence-based practices while highlighting areas for improvement, particularly in resource allocation and documentation. The findings underscore the need for culturally sensitive adaptations of fidelity measures and innovative solutions to address challenges in early psychosis services within Asian healthcare systems. Future research should focus on developing structured documentation systems that balance standardisation with personalised care and explore strategies to enhance metabolic health interventions and substance use management in the local context.
