Benefits and harms of copyright restrictions and conditions on burnout and other psychometric assessment scales.
Article in PloS one, 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
introductionCopyright conditions can hinder the scientific and usage impact of essential assessment tools in healthcare, organizational psychology, and other fields. The stories of the Maslach Burnout Inventory (MBI) and the Mini-Mental Status Examination (MMSE) are well-documented. Despite decades-old recommendations to blend copyright restrictions of intellectual property when used for commercial purposes with permissive but distinct copyright terms for non-commercial and scholarly use, few authors of assessment tools do so.
objectiveTo assess whether restrictive copyrights limit the long-term scientific impact of copyright holders (often medical schools/faculty), by inhibiting downstream use, research, and improvement of measurement tools by other researchers.
methodsWe compared MEDLINE citation trends of two restrictive surveys (requiring royalty payments, prohibiting item modifications) - the Maslach Burnout Inventory (MBI) and the Mini-Mental Status Examination (MMSE) - against four free-to-use and adapt surveys. Our outcome was the annual, theme-relevant citation ratio of each survey since publication. The ratio was the number of publications featuring the scale name in the title or abstract divided by total publications addressing the original theme (purpose) of the scale. We performed paired comparisons of the most recent slopes of the annual citation ratio, pairing each restrictive scale with a permissive scale, totaling eight comparisons.
resultsThe restrictive MBI and MMSE initially showed rising slopes of annual citation ratios, and a decline in later years with negative slopes. Further, the final slope segments for all four permissive surveys were positive, vs. negative for the restrictive surveys, the slope difference being statistically significant for six out of eight comparisons.
conclusionsRestrictive copyright conditions on assessment scales risk undermining their long-term scientific and functional relevance. Previously recommended blended copyright approaches can facilitate survey creators' revenues via commercial use royalties, while sustaining continued scholarly development and noncommercial usage to improve long-term relevance.
