Validation of the Demand Control Support Questionnaire for European Portuguese.
Article in Portuguese journal of public health, 2023. 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: The Demand Control Support model is useful for studying work-related stress. The combination of high demand and a low level of control generates "job strain" ("job iso-strain" if poor support is added), with implications for the worker's health and well-being. The aims of this study were to adapt, examine the factor structure of, and determine the reliability of, the Demand Control Support Questionnaire (DCSQ) short version for European Portuguese (DCSQ-PT). Methods: The scale was translated into Portuguese following a rigorous process and then applied to 501 workers from various professional sectors. An online survey was used to collect sociodemographic, professional, and Demand Control Support data. Validation was based on reliability and validity tests. Results: The mean age of the sample was 41.8 ± 10.3 years, and 50.1% of the participants were female. The results reveal good reliability (Cronbach's alpha = 0.807) and validity. Confirmatory factor analyses demonstrated that a four-factor solution of the DCSQ-PT scale had a good fit to the data, as was the case for the original scale. The DCSQ-PT Conclusions: This validation allows an instrument to be obtained with 16 items for studying work-related stress in Portuguese workers.
