Climate Change Distress (But Not Impairment) Mediates the Relationship Between Positive Traits and Pro-Environmental Behaviour

Personality traits are essential to understanding individual differences in values, attitudes, behaviours, and cognitive-emotional reactions to climate change (CC). Prosocial traits (empathy and altruism) and nature relatedness (NR), that is, the subjective sense of connection with the natural world, have been linked both to pro-environmental behaviours (PEB) and to CC-related psychological distress. As these reactions are increasingly common in the context of CC, it is crucial to distinguish their adaptive components from their maladaptive ones, namely, by identifying which psychological predictors most strongly promote PEB, in order to design targeted interventions and communication strategies that effectively foster sustainable action. This study examined whether CC-worry, CC-distress, and CC-impairment mediate the relationships between prosocial traits, NR, and PEB. A community sample of 577 adults (mean age = 32.62 ± 14.71 years; 64.6% women) completed self-report measures of the abovementioned study variables, and a multiple mediation model using structural equation modelling was tested. Prosocial traits and NR were positively associated with CC-related psychological distress and PEB, and CC-worry and CC-distress showed significant mediating roles, whereas CC-impairment did not. The model explained 40% of PEB’s variance. Overall, CC-worry and CC-distress appear to function as adaptive, motivational processes that link positive traits and nature connection to environmental action, while CC-impairment reflects a maladaptive, unconstructive response that may index the more pathological end of climate change-related psychological distress.
