A Fidelity Assessment of Early Psychosis Intervention Services in British Columbia, Canada.
Article in Early intervention in psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionEstablished standards and guidelines for early psychosis intervention (EPI) in British Columbia (BC) and across Canada define the intent and scope of individual EPI programs. EPI programs are a critical mental health service both in BC and internationally, providing a range of pharmacological, psychological, and social supports under one service. If EPI principles and practices are applied, positive outcomes are expected, including greater reduction of psychotic symptoms compared to standard treatment, improved treatment adherence, fewer recurrent episodes of psychosis, and greater client satisfaction. Low fidelity, or difficulty adhering to the principles associated with the EPI model, may jeopardize attaining these positive outcomes.
methodsEvaluation of program fidelity to established EPI practice standards and guidelines was conducted at 16 mental health service sites in BC that provide care to young adults with early psychosis. Fidelity assessment was performed via utilization of the EPI Fidelity Scale (EPI-FS).
resultsBased on the EPI-FS, two sites (12.5%) met criteria for high fidelity, nine (56.3%) attained moderate fidelity, three (18.8%) attained low fidelity, and two (12.5%) attained very low fidelity. Specialized EPI programs were linked to higher fidelity, while many generic mental health and substance use centres had difficulty following the EPI model. Identified weaknesses included provision of psychological therapy, family education, ongoing program evaluation, and supervision and mentorship for clinicians. Sites with sufficient resources and staff development opportunities had higher overall fidelity.
conclusionThese findings underscore the importance of equitable resource allocation and the need for specialized EPI services, especially in underserved areas in BC.
