Usefulness of the Brief Job Stress Questionnaire to identify employees at risk of depression in the Japanese Stress Check Program: a large-scale cross-sectional study.

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
Objectives: The Japanese National Stress Check Program recommends the Brief Job Stress Questionnaire (BJSQ) for annual psychosocial assessments in the workplace. We examined the performance of this instrument in screening depression. Methods: We conducted an online cross-sectional study involving 25,000 employees in October 2024. Participants completed the BJSQ and the nine-item Patient Health Questionnaire (PHQ-9). We conducted receiver operating characteristic curve analyses to estimate the screening performance of the BJSQ cutoff points recommended in the Stress Check Program manual. Results: The prevalence of workers with potential depression (PHQ-9 score ≥10) was 25.9%. The prevalence of "high-risk" employees defined using the BJSQ criteria recommended in the Program manual was 18.8%, with sensitivity of 50.9%, specificity of 92.4%, Youden index of 0.433, area under the curve of 0.716, positive predictive value of 70.0%, negative predictive value of 84.8%, and positive and negative likelihood ratios of 6.7 and 0.5, respectively. Conclusion: Identifying "high stress" employees as per the Stress Check Program manual recommendation is informative to screen employees with potential depression provided that appropriate follow-up is undertaken. When using this information, practitioners should consider its limitations as a screening tool.
