Does Mindfulness Mediate the Relationship Between Emotion Regulation and Pro-Environmental Behaviors Differently Based on Gender?

Objectives This study aimed to explore possible gender differences in the relationship between emotion dysregulation, mindfulness, and pro-environmental behaviors. Specifically, it aimed to investigate whether mindfulness mediated the association between emotion dysregulation and pro-environmental behaviors, and if there were any gender differences in this relationship. Method A sample of 1,406 employees (56.3% males, average age = 44.85) participated in the study. Participants completed the Pro-Environmental Behaviors Scale (PEBS), Difficulties in Emotion Regulation Scale- Short Form (DERS-SF), and Five Facet Mindfulness Questionnaire (FFMQ) to assess pro-environmental behaviors, emotion regulation, and mindfulness, respectively. Data were analyzed using ANOVA, Pearson's correlation analysis, and mediation analysis. Results Women exhibited higher scores on the PEBS total scale ( p < 0.001; 𝜂 2 = 0.02), higher scores on the Observe and Describe FFMQ subscales ( p < 0.001; 𝜂 2 = 0.01), and lower scores on the Non-react FFMQ subscale ( p < 0.001; 𝜂 2 = 0.01), compared to men. No gender differences were found on the DERS-SF total scale ( p > 0.05; 𝜂 2 = 0.00). Higher levels of emotion dysregulation were associated with lower pro-environmental behaviors ( r = - 0.12; p < 0.05). Mindfulness mediated the relationship between emotion dysregulation and pro-environmental behaviors, specifically through the ability to observe one's own emotions and external stimuli. Gender differences were found based on the Non-react facet of mindfulness, which is negatively associated with pro-environmental behaviors in men ( β = - 0.08; p < 0.05) and positively associated with them in women ( β = 0.09; p < 0.05). Conclusions The findings suggest that emotion dysregulation and mindfulness are associated with pro-environmental behaviors. The ability to observe one's own emotions and external stimuli plays a significant role in promoting sustainable behaviors, while the ability to perceive one's own emotions without feeling overwhelmed or compelled to react to them has different associations with pro-environmental behaviors in men and women. These results provide insights for the development of interventions targeting emotion regulation and mindfulness to encourage pro-environmental behaviors, specifically based on gender.
