Results of the validated German Perceived Stress Questionnaire (PSQ) from a large German cohort of healthy adults and different disease groups compared to historical reference values.
Article in European archives of psychiatry and clinical neuroscience, 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
backgroundReference values of the validated German Perceived Stress Questionnaire (PSQ) were published in 2005 for healthy adults and individuals with different clinical conditions. We compared historical values with PSQ from the large German cohort participating in "Risk Factors for COVID-19 Vaccine Failure study (RisCoin).
methodsIn late 2021, we enrolled 4115 adults: hospital employees or patients with inflammatory bowel disease (IBD) or psychiatric disorders with ≥ 2 COVID-19 vaccinations. Participants completed extensive questionnaires including PSQ. Healthcare workers (HCW) were categorized as HCW-healthy or HCW-plus (any chronic medical condition). PSQ total and domain scores (worries, tension, joy, demands) were compared to reference values. Multivariable logistic regression identified factors associated with cohort-specific high scores (mean + 1SD).
resultsHCW-healthy (N = 1998, mean age ± SD: 38 ± 12 years) reached higher mean total PSQ scores than historical healthy individuals (36 ± 18 vs. 33 ± 17, respectively, p<0.001), but lower scores (40 ± 19, p < 0.001) than HCW-plus (N = 1717, 43 ± 13 years). Female HCW-healthy perceived higher stress than males, especially at younger age. Participants with IBD (N = 161, 45 ± 15 years) exhibited lower scores than historical IBD patients (38 ± 19 vs. 43 ± 17, p < 0.001); psychiatric patients (N = 100, 41 ± 15 years) showed the highest scores (60 ± 19). Among HCW, female gender, frequent consumption of ready-to-eat meals/foods, and living with children were associated with higher, whereas regular physical activity and healthy dietary habits with lower PSQ scores.
conclusionAssuming representativeness of our cohort, these PSQ data could serve as updated benchmark for future research.
