Portuguese version of Bern Illegitimates Task Scale: adaptation and evidence of validity.
Article in BMC psychology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundA new element for job stress called Illegitimate Tasks has been investigated in recent years, along with stress as an offense to self-theory. Illegitimate tasks are those that are either needless or unrelated to the employee's role and can be categorized as unreasonable tasks and unnecessary tasks.
methodsThis study aimed to adapt the Bern Illegitimate Tasks Scale to Portuguese and provide evidence of its validity, through a confirmatory factor analysis with a sample of 472 workers from different sectors.
resultsThe internal consistency, of the whole scale, measured by Cronbach's alpha, was 0.923 and 0.902 and 0.928 for the unnecessary tasks and, for unreasonable tasks subscales respectively. The confirmatory analysis supported a two-factor model and showed good to very good indexes of fit (CFI = 0.985; TLI = 0.997; SRMR = 0.035; RMSEA = 0.171). DISCUSSION: The Portuguese version of the Bern Illegitimate Tasks Scale presents very good psychometric properties for the intended measurement goals and can now be used in research with Portuguese speaking samples.
