Development and Validation of a Self-Management Motivation Scale for Children with Chronic Diseases.
Article in Patient preference and adherence, 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
Background: Self-Determination Theory highlights the role of motivation in sustaining self-management behaviors among children with chronic diseases, but validated instruments for assessing this construct in pediatric populations are limited. This study developed and validated a self-management motivation scale for children aged 8-18 years with chronic diseases. Methods: Scale development proceeded in sequential phases. First, the initial item pool was developed by integrating evidence from relevant literature with findings from semi-structured interviews (n = 22). Second, items were refined through a two-round Delphi consultation with 20 experts to evaluate item importance and relevance, with expert authority and consensus assessed, followed by two rounds of cognitive interviews (n=13) and a pilot survey, yielding a 24-item preliminary scale. Third, item analysis was conducted in 143 children to remove poorly performing items. Finally, psychometric evaluation was performed in 386 children, including content validity, factor structure through EFA (n = 155) and CFA (n = 231), convergent and discriminant validity, internal consistency, split-half reliability, and test-retest reliability (n=30). Results: The final scale comprised 21 items across four dimensions: autonomous motivation, introjected regulation, external regulation, and amotivation. Content validity was strong (I-CVI=0.875-1.000; S-CVI/Ave=0.988). A four-factor structure emerged from the exploratory factor analysis, explaining 75.84% of the variance. Confirmatory factor analysis demonstrated a good model fit (χ Conclusion: The scale demonstrated satisfactory reliability and validity for assessing self-management motivation in children with chronic diseases. Further longitudinal and multicenter studies are needed to examine its predictive validity and intervention responsiveness.
