Exploring the Potential of a Scenario-Based Approach to Early Autism Spectrum Disorder Screening.
Article in Psychiatry investigation, 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
objectiveTo evaluate the feasibility and screening accuracy of a brief scenario-based, video-delivered tool for early identification of autism spectrum disorder (ASD) in young children.
methodsData were analyzed from 211 children aged 12-42 months (ASD [n=140], other developmental disorders [OD] [n=35], and typically developing [TD] [n=36]) who completed a 5-minute scenario-based ASD early screening tool eliciting eight target behaviors: initiation/response to joint attention, response to name, eye contact, social referencing, imitation, social smiling, and pointing. Behaviors were scored using two criteria (0-16 symptom score; number of activities with partial or complete non-response). Diagnostic classification (ASD, OD, and TD) followed best-estimate diagnoses integrating Korean Version of the Autism Diagnostic Observation Schedule, Korean Version of the Autism Diagnostic Interview-Revised, Behavior Development Screening for Toddlers, Social Responsiveness Scale 2nd edition, Social Communication Questionnaire, and Korean Version of the Vineland Adaptive Behavior Scales-Second Edition. Group differences and screening performance were examined with analysis of variance, chi-square tests, and receiver operating characteristic analyses.
resultsSignificant group differences emerged for response to name, eye contact, pointing, social referencing, social smiling, and initiation of joint attention, especially between ASD and non-ASD groups. Across scoring methods, children with ASD showed higher total scores and more non-responsive activities (all p<0.001). Area under the curve values were 0.703 for the total score and 0.676 and 0.700 for the two non-response indices, indicating good overall discrimination with relatively high sensitivity and modest specificity.
conclusionThis scenario-based ASD early screening tool shows promising feasibility and accuracy as a brief, standardized video screener for toddlers and preschoolers. With its accessibility and scalability, it has potential for widespread use in community and home settings, warranting further refinement to improve specificity and implementation in real-world practice.
