Effects of uncertainty stress on attentional control in college students: mediating effect of problematic mobile phone use and moderating effect of expressive suppression.
Article in BMC psychology, 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
backgroundCollege students are susceptible to developing uncertainty stress. Uncertainty raises a range of issues that may affect attentional control. The aim of this study was to examine the pathways and moderators of the relationship between uncertainty stress and attentional control in college students.
methodsThis cross-sectional study recruited 408 college students by completing questionnaires on problematic mobile phone use, expression repression, uncertainty stress, and attentional control. Moderated mediated effects were examined using the PROCESS plug-in integrated into SPSS.
resultsThere was a significantly negative correlation found between uncertainty stress and attentional control. This link may have been mediated by problematic mobile phone use. The effects of uncertainty stress on problematic mobile phone use and attentional control were mitigated by expressive suppression. Specifically, the direct impairing effect of uncertainty stress on attentional control and the indirect impairing effect through problematic mobile phone use were stronger for college students with higher levels of expressive suppression.
conclusionThis study enriches our understanding of how uncertainty stress impairs attentional control. To support college students in maintaining attentional control, educators should provide particular attention to those with greater levels of uncertainty stress, particularly those with higher levels of problematic mobile phone use and expressive suppression.
