Validity and reliability of the Chinese version of the Jenkins Sleep Scale among university students in China.
Article in PeerJ, 2025. 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 Chinese version of the Jenkins Sleep Scale (JSS-C) is widely used; however, it lacks formal validation, and its applicability to Chinese university students has not been examined. This study evaluated the validity and reliability of the JSS-C in this population, with a focus on gender differences. Methods: A cross-sectional study was conducted with 1,534 Chinese university students (29.6% male, 70.4% female; mean age = 19.83 ± 1.54 years) recruited through convenience sampling. Participants completed the JSS-C, which assesses sleep disturbances across four key domains. Confirmatory factor analysis was used to examine construct validity. Internal consistency (Cronbach's alpha) and composite reliability (CR) were calculated to assess reliability. Measurement invariance testing across gender groups was conducted to evaluate the scale's robustness. Results: Confirmatory factor analysis supported a strong one-factor structure for the JSS-C, with excellent model fit indices ( Conclusion: The JSS-C is a brief, valid, and reliable instrument for assessing sleep disturbances among Chinese university students. Its standardized scores support meaningful gender-based comparisons.
