Feasibility and Effectiveness of the WHO Caregiver Skills Training Program in South Korea: Adaptation to an Online Video-Based Coaching Model.
Article in Journal of autism and developmental disorders, 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
objectivesParent-mediated interventions are a core component of services for children with autism and other neurodevelopmental conditions. This study evaluated the feasibility and preliminary effectiveness of the World Health Organization's Caregiver Skills Training (WHO CST) program in South Korea, including its adaptation to an online, video-based delivery model.
methodsA pre-pilot study was conducted between 2018 and 2020 with 50 caregiver-child dyads. During the COVID-19 pandemic, the program transitioned from in-person to synchronous online delivery. In the online format, caregivers practiced intervention strategies in naturalistic home settings and submitted video recordings of caregiver-child interactions. These recordings were reviewed by facilitators to provide individualized feedback during virtual home visits. The core content and structure of the CST program were maintained across delivery formats. Outcomes were assessed using measures of child functioning (WHODAS-C), caregiver knowledge and skills (CKST), and caregiver stress (PSS).
resultsSignificant improvements were observed following the intervention in child functioning, caregiver knowledge and skills, and caregiver stress (all p < .001). No significant differences were found between in-person and online delivery formats, although the online group demonstrated broader improvements across child functional domains. The online CST program implemented from 2020 to 2025 demonstrated strong feasibility, with high retention rates in both in-person (88%) and consistently high caregiver satisfaction (mean scores > 4.5 out of 5).
conclusionsThese findings suggest that WHO CST can be feasibly and effectively implemented in South Korea, and that online delivery incorporating video-based coaching represents a viable approach for expanding access to caregiver-mediated interventions.
