Too drained to help? How work overload fuels psychological strain and why proactive personality functions as a buffer.
Article in Frontiers in psychology, 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
By integrating the job demands-resources (JD-R) model with the proactivity literature, this study investigates the psychological mechanism and boundary condition that link work overload to helping behavior. We test our hypotheses using a four-wave, multi-source dataset from 366 employee-supervisor dyads in a manufacturing firm in China. The findings show that work overload is positively related to psychological strain, which in turn reduces helping behavior. Moreover, proactive personality functions as a critical personal resource; it buffers the detrimental effect of work overload on psychological strain, thereby weakening the indirect negative effect of work overload on helping behavior. These results contribute to the literature by uncovering the resource-depletion pathway between job demands and helping behavior, while highlighting proactive personality as an agentic, behavioral trait that drives employees to managing heavy workloads and sustain resource-sensitive helping behavior in demanding work environments.
