The impact of mortality salience and explicit self-esteem on plastic reduction intention: A moderated mediation model.
Article in PloS one, 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
Mortality salience (MS) and self-esteem affect attitudes and behavioral intentions in various contexts, including pro-environment behavioral intentions. This study aimed to explore how MS and explicit self-esteem impact on attitude towards plastic reduction for future generations (APRFG) and intention to reduce plastic use, by integrating the Theory of Planned Behavior (TPB) and Terror Management Theory (TMT). An experimental design was employed, with 357 participants aged 20 to 70 recruited via an online platform. The participants were randomly assigned to either an MS condition, or a control condition and then measured their explicit self-esteem by the Rosenberg Self-Esteem Scale. Subsequently, the experimental group was exposed to information on the fatal health risks associated with microplastics, while the control group was reminded of their own experiences of dental pain. After a few minutes, all participants were asked to complete a self-report questionnaire, including APRFG, subjective norm, perceived behavioral control, and intention to reduce plastic use. Data were analyzed using the PROCESS macro to examine mediation and moderation effects. Our findings showed that MS significantly enhanced APRFG, subjective norm, and perceived behavioral control, which in turn led to stronger intention to reduce plastic use. Among these three factors, the mediating effect of APRFG was the most pronounced, highlighting its central role in linking MS to plastic reduction intention. MS, when combined with explicit self-esteem, significantly influences APRFG and intention to reduce plastic use. The relationships between MS and APRFG/plastic reduction intention were particularly pronounced among the participants with lower explicit self-esteem. Policymakers can leverage these insights to craft marketing messages that enhance plastic-reduction efforts, taking into account individual differences in explicit self-esteem.
